/proc/irq/IRQ#/smp_affinity specifies which target CPUs are permitted
for a given IRQ source. It's a bitmask of allowed CPUs. It's not allowed
to turn off all CPUs, and if an IRQ controller does not support IRQ
affinity then the value will not change from the default 0xffffffff.

- a. Make updates appear atomic to readers. For example,
+ a. Use the RCU variants of the list and hlist update

pointer updates to properly aligned fields will appear
atomic, as will individual atomic primitives. Operations

+rule (c), you should ask the submitter to rediff, but this is a totally

+This is a summary of the most important conventions for use of fault
+codes in the I2C/SMBus stack.
+
+
+A "Fault" is not always an "Error"
+----------------------------------
+Not all fault reports imply errors; "page faults" should be a familiar
+example. Software often retries idempotent operations after transient
+faults. There may be fancier recovery schemes that are appropriate in
+some cases, such as re-initializing (and maybe resetting). After such
+recovery, triggered by a fault report, there is no error.
+
+In a similar way, sometimes a "fault" code just reports one defined
+result for an operation ... it doesn't indicate that anything is wrong
+at all, just that the outcome wasn't on the "golden path".
+
+In short, your I2C driver code may need to know these codes in order
+to respond correctly. Other code may need to rely on YOUR code reporting
+the right fault code, so that it can (in turn) behave correctly.
+
+
+I2C and SMBus fault codes
+-------------------------
+These are returned as negative numbers from most calls, with zero or
+some positive number indicating a non-fault return. The specific
+numbers associated with these symbols differ between architectures,
+though most Linux systems use <asm-generic/errno*.h> numbering.
+
+Note that the descriptions here are not exhaustive. There are other
+codes that may be returned, and other cases where these codes should
+be returned. However, drivers should not return other codes for these
+cases (unless the hardware doesn't provide unique fault reports).
+
+Also, codes returned by adapter probe methods follow rules which are
+specific to their host bus (such as PCI, or the platform bus).
+
+
+EAGAIN
+ Returned by I2C adapters when they lose arbitration in master
+ transmit mode: some other master was transmitting different
+ data at the same time.
+
+ Also returned when trying to invoke an I2C operation in an
+ atomic context, when some task is already using that I2C bus
+ to execute some other operation.
+
+EBADMSG
+ Returned by SMBus logic when an invalid Packet Error Code byte
+ is received. This code is a CRC covering all bytes in the
+ transaction, and is sent before the terminating STOP. This
+ fault is only reported on read transactions; the SMBus slave
+ may have a way to report PEC mismatches on writes from the
+ host. Note that even if PECs are in use, you should not rely
+ on these as the only way to detect incorrect data transfers.
+
+EBUSY
+ Returned by SMBus adapters when the bus was busy for longer
+ than allowed. This usually indicates some device (maybe the
+ SMBus adapter) needs some fault recovery (such as resetting),
+ or that the reset was attempted but failed.
+
+EINVAL
+ This rather vague error means an invalid parameter has been
+ detected before any I/O operation was started. Use a more
+ specific fault code when you can.
+
+ One example would be a driver trying an SMBus Block Write
+ with block size outside the range of 1-32 bytes.
+
+EIO
+ This rather vague error means something went wrong when
+ performing an I/O operation. Use a more specific fault
+ code when you can.
+
+ENODEV
+ Returned by driver probe() methods. This is a bit more
+ specific than ENXIO, implying the problem isn't with the
+ address, but with the device found there. Driver probes
+ may verify the device returns *correct* responses, and
+ return this as appropriate. (The driver core will warn
+ about probe faults other than ENXIO and ENODEV.)
+
+ENOMEM
+ Returned by any component that can't allocate memory when
+ it needs to do so.
+
+ENXIO
+ Returned by I2C adapters to indicate that the address phase
+ of a transfer didn't get an ACK. While it might just mean
+ an I2C device was temporarily not responding, usually it
+ means there's nothing listening at that address.
+
+ Returned by driver probe() methods to indicate that they
+ found no device to bind to. (ENODEV may also be used.)
+
+EOPNOTSUPP
+ Returned by an adapter when asked to perform an operation
+ that it doesn't, or can't, support.
+
+ For example, this would be returned when an adapter that
+ doesn't support SMBus block transfers is asked to execute
+ one. In that case, the driver making that request should
+ have verified that functionality was supported before it
+ made that block transfer request.
+
+ Similarly, if an I2C adapter can't execute all legal I2C
+ messages, it should return this when asked to perform a
+ transaction it can't. (These limitations can't be seen in
+ the adapter's functionality mask, since the assumption is
+ that if an adapter supports I2C it supports all of I2C.)
+
+EPROTO
+ Returned when slave does not conform to the relevant I2C
+ or SMBus (or chip-specific) protocol specifications. One
+ case is when the length of an SMBus block data response
+ (from the SMBus slave) is outside the range 1-32 bytes.
+
+ETIMEDOUT
+ This is returned by drivers when an operation took too much
+ time, and was aborted before it completed.
+
+ SMBus adapters may return it when an operation took more
+ time than allowed by the SMBus specification; for example,
+ when a slave stretches clocks too far. I2C has no such
+ timeouts, but it's normal for I2C adapters to impose some
+ arbitrary limits (much longer than SMBus!) too.

+Paravirt_ops on IA64
+====================
+ 21 May 2008, Isaku Yamahata <yamahata@valinux.co.jp>
+
+
+Introduction
+------------
+The aim of this documentation is to help with maintainability and/or to
+encourage people to use paravirt_ops/IA64.
+
+paravirt_ops (pv_ops in short) is a way for virtualization support of
+Linux kernel on x86. Several ways for virtualization support were
+proposed, paravirt_ops is the winner.
+On the other hand, now there are also several IA64 virtualization
+technologies like kvm/IA64, xen/IA64 and many other academic IA64
+hypervisors so that it is good to add generic virtualization
+infrastructure on Linux/IA64.
+
+
+What is paravirt_ops?
+---------------------
+It has been developed on x86 as virtualization support via API, not ABI.
+It allows each hypervisor to override operations which are important for
+hypervisors at API level. And it allows a single kernel binary to run on
+all supported execution environments including native machine.
+Essentially paravirt_ops is a set of function pointers which represent
+operations corresponding to low level sensitive instructions and high
+level functionalities in various area. But one significant difference
+from usual function pointer table is that it allows optimization with
+binary patch. It is because some of these operations are very
+performance sensitive and indirect call overhead is not negligible.
+With binary patch, indirect C function call can be transformed into
+direct C function call or in-place execution to eliminate the overhead.
+
+Thus, operations of paravirt_ops are classified into three categories.
+- simple indirect call
+ These operations correspond to high level functionality so that the
+ overhead of indirect call isn't very important.
+
+- indirect call which allows optimization with binary patch
+ Usually these operations correspond to low level instructions. They
+ are called frequently and performance critical. So the overhead is
+ very important.
+
+- a set of macros for hand written assembly code
+ Hand written assembly codes (.S files) also need paravirtualization
+ because they include sensitive instructions or some of code paths in
+ them are very performance critical.
+
+
+The relation to the IA64 machine vector
+---------------------------------------
+Linux/IA64 has the IA64 machine vector functionality which allows the
+kernel to switch implementations (e.g. initialization, ipi, dma api...)
+depending on executing platform.
+We can replace some implementations very easily defining a new machine
+vector. Thus another approach for virtualization support would be
+enhancing the machine vector functionality.
+But paravirt_ops approach was taken because
+- virtualization support needs wider support than machine vector does.
+ e.g. low level instruction paravirtualization. It must be
+ initialized very early before platform detection.
+
+- virtualization support needs more functionality like binary patch.
+ Probably the calling overhead might not be very large compared to the
+ emulation overhead of virtualization. However in the native case, the
+ overhead should be eliminated completely.
+ A single kernel binary should run on each environment including native,
+ and the overhead of paravirt_ops on native environment should be as
+ small as possible.
+
+- for full virtualization technology, e.g. KVM/IA64 or
+ Xen/IA64 HVM domain, the result would be
+ (the emulated platform machine vector. probably dig) + (pv_ops).
+ This means that the virtualization support layer should be under
+ the machine vector layer.
+
+Possibly it might be better to move some function pointers from
+paravirt_ops to machine vector. In fact, Xen domU case utilizes both
+pv_ops and machine vector.
+
+
+IA64 paravirt_ops
+-----------------
+In this section, the concrete paravirt_ops will be discussed.
+Because of the architecture difference between ia64 and x86, the
+resulting set of functions is very different from x86 pv_ops.
+
+- C function pointer tables
+They are not very performance critical so that simple C indirect
+function call is acceptable. The following structures are defined at
+this moment. For details see linux/include/asm-ia64/paravirt.h
+ - struct pv_info
+ This structure describes the execution environment.
+ - struct pv_init_ops
+ This structure describes the various initialization hooks.
+ - struct pv_iosapic_ops
+ This structure describes hooks to iosapic operations.
+ - struct pv_irq_ops
+ This structure describes hooks to irq related operations
+ - struct pv_time_op
+ This structure describes hooks to steal time accounting.
+
+- a set of indirect calls which need optimization
+Currently this class of functions correspond to a subset of IA64
+intrinsics. At this moment the optimization with binary patch isn't
+implemented yet.
+struct pv_cpu_op is defined. For details see
+linux/include/asm-ia64/paravirt_privop.h
+Mostly they correspond to ia64 intrinsics 1-to-1.
+Caveat: Now they are defined as C indirect function pointers, but in
+order to support binary patch optimization, they will be changed
+using GCC extended inline assembly code.
+
+- a set of macros for hand written assembly code (.S files)
+For maintenance purpose, the taken approach for .S files is single
+source code and compile multiple times with different macros definitions.
+Each pv_ops instance must define those macros to compile.
+The important thing here is that sensitive, but non-privileged
+instructions must be paravirtualized and that some privileged
+instructions also need paravirtualization for reasonable performance.
+Developers who modify .S files must be aware of that. At this moment
+an easy checker is implemented to detect paravirtualization breakage.
+But it doesn't cover all the cases.
+
+Sometimes this set of macros is called pv_cpu_asm_op. But there is no
+corresponding structure in the source code.
+Those macros mostly 1:1 correspond to a subset of privileged
+instructions. See linux/include/asm-ia64/native/inst.h.
+And some functions written in assembly also need to be overrided so
+that each pv_ops instance have to define some macros. Again see
+linux/include/asm-ia64/native/inst.h.
+
+
+Those structures must be initialized very early before start_kernel.
+Probably initialized in head.S using multi entry point or some other trick.
+For native case implementation see linux/arch/ia64/kernel/paravirt.c.

kernel-doc nano-HOWTO
=====================
+How to format kernel-doc comments
+---------------------------------
+
+In order to provide embedded, 'C' friendly, easy to maintain,
+but consistent and extractable documentation of the functions and
+data structures in the Linux kernel, the Linux kernel has adopted
+a consistent style for documenting functions and their parameters,
+and structures and their members.
+
+The format for this documentation is called the kernel-doc format.
+It is documented in this Documentation/kernel-doc-nano-HOWTO.txt file.
+
+This style embeds the documentation within the source files, using
+a few simple conventions. The scripts/kernel-doc perl script, some
+SGML templates in Documentation/DocBook, and other tools understand
+these conventions, and are used to extract this embedded documentation
+into various documents.
+
+In order to provide good documentation of kernel functions and data
+structures, please use the following conventions to format your
+kernel-doc comments in Linux kernel source.
+
+We definitely need kernel-doc formatted documentation for functions
+that are exported to loadable modules using EXPORT_SYMBOL.
+
+We also look to provide kernel-doc formatted documentation for
+functions externally visible to other kernel files (not marked
+"static").
+
+We also recommend providing kernel-doc formatted documentation
+for private (file "static") routines, for consistency of kernel
+source code layout. But this is lower priority and at the
+discretion of the MAINTAINER of that kernel source file.
+
+Data structures visible in kernel include files should also be
+documented using kernel-doc formatted comments.
+
+The opening comment mark "/**" is reserved for kernel-doc comments.
+Only comments so marked will be considered by the kernel-doc scripts,
+and any comment so marked must be in kernel-doc format. Do not use
+"/**" to be begin a comment block unless the comment block contains
+kernel-doc formatted comments. The closing comment marker for
+kernel-doc comments can be either "*/" or "**/".
+
+Kernel-doc comments should be placed just before the function
+or data structure being described.
+
+Example kernel-doc function comment:
+
+/**
+ * foobar() - short function description of foobar
+ * @arg1: Describe the first argument to foobar.
+ * @arg2: Describe the second argument to foobar.
+ * One can provide multiple line descriptions
+ * for arguments.
+ *
+ * A longer description, with more discussion of the function foobar()
+ * that might be useful to those using or modifying it. Begins with
+ * empty comment line, and may include additional embedded empty
+ * comment lines.
+ *
+ * The longer description can have multiple paragraphs.
+ **/
+
+The first line, with the short description, must be on a single line.
+
+The @argument descriptions must begin on the very next line following
+this opening short function description line, with no intervening
+empty comment lines.
+
+Example kernel-doc data structure comment.
+
+/**
+ * struct blah - the basic blah structure
+ * @mem1: describe the first member of struct blah
+ * @mem2: describe the second member of struct blah,
+ * perhaps with more lines and words.
+ *
+ * Longer description of this structure.
+ **/
+
+The kernel-doc function comments describe each parameter to the
+function, in order, with the @name lines.
+
+The kernel-doc data structure comments describe each structure member
+in the data structure, with the @name lines.
+
+The longer description formatting is "reflowed", losing your line
+breaks. So presenting carefully formatted lists within these
+descriptions won't work so well; derived documentation will lose
+the formatting.
+
+See the section below "How to add extractable documentation to your
+source files" for more details and notes on how to format kernel-doc
+comments.
+
+Components of the kernel-doc system
+-----------------------------------
+
Many places in the source tree have extractable documentation in the
form of block comments above functions. The components of this system
are:

+the Nouveau project as the first real user. Only x86 and x86_64 architectures
+are supported.
+
+Out-of-tree mmiotrace was originally modified for mainline inclusion and
+ftrace framework by Pekka Paalanen <pq@iki.fi>.
+
+
+Preparation
+-----------
+
+Mmiotrace feature is compiled in by the CONFIG_MMIOTRACE option. Tracing is
+disabled by default, so it is safe to have this set to yes. SMP systems are
+supported, but tracing is unreliable and may miss events if more than one CPU
+is on-line, therefore mmiotrace takes all but one CPU off-line during run-time
+activation. You can re-enable CPUs by hand, but you have been warned, there
+is no way to automatically detect if you are losing events due to CPUs racing.
+
+
+Usage Quick Reference
+---------------------
+
+$ mount -t debugfs debugfs /debug
+$ echo mmiotrace > /debug/tracing/current_tracer
+$ cat /debug/tracing/trace_pipe > mydump.txt &
+Start X or whatever.
+$ echo "X is up" > /debug/tracing/marker
+$ echo none > /debug/tracing/current_tracer
+Check for lost events.
+
+
+Usage
+-----
+
+Make sure debugfs is mounted to /debug. If not, (requires root privileges)
+$ mount -t debugfs debugfs /debug
+
+Check that the driver you are about to trace is not loaded.
+
+Activate mmiotrace (requires root privileges):
+$ echo mmiotrace > /debug/tracing/current_tracer
+
+Start storing the trace:
+$ cat /debug/tracing/trace_pipe > mydump.txt &
+The 'cat' process should stay running (sleeping) in the background.
+
+Load the driver you want to trace and use it. Mmiotrace will only catch MMIO
+accesses to areas that are ioremapped while mmiotrace is active.
+
+[Unimplemented feature:]
+During tracing you can place comments (markers) into the trace by
+$ echo "X is up" > /debug/tracing/marker
+This makes it easier to see which part of the (huge) trace corresponds to
+which action. It is recommended to place descriptive markers about what you
+do.
+
+Shut down mmiotrace (requires root privileges):
+$ echo none > /debug/tracing/current_tracer
+The 'cat' process exits. If it does not, kill it by issuing 'fg' command and
+pressing ctrl+c.
+
+Check that mmiotrace did not lose events due to a buffer filling up. Either
+$ grep -i lost mydump.txt
+which tells you exactly how many events were lost, or use
+$ dmesg
+to view your kernel log and look for "mmiotrace has lost events" warning. If
+events were lost, the trace is incomplete. You should enlarge the buffers and
+try again. Buffers are enlarged by first seeing how large the current buffers
+are:
+$ cat /debug/tracing/trace_entries
+gives you a number. Approximately double this number and write it back, for
+instance:
+$ echo 128000 > /debug/tracing/trace_entries
+Then start again from the top.
+
+If you are doing a trace for a driver project, e.g. Nouveau, you should also
+do the following before sending your results:
+$ lspci -vvv > lspci.txt
+$ dmesg > dmesg.txt
+$ tar zcf pciid-nick-mmiotrace.tar.gz mydump.txt lspci.txt dmesg.txt
+and then send the .tar.gz file. The trace compresses considerably. Replace
+"pciid" and "nick" with the PCI ID or model name of your piece of hardware
+under investigation and your nick name.
+
+
+How Mmiotrace Works
+-------------------
+
+Access to hardware IO-memory is gained by mapping addresses from PCI bus by
+calling one of the ioremap_*() functions. Mmiotrace is hooked into the
+__ioremap() function and gets called whenever a mapping is created. Mapping is
+an event that is recorded into the trace log. Note, that ISA range mappings
+are not caught, since the mapping always exists and is returned directly.
+
+MMIO accesses are recorded via page faults. Just before __ioremap() returns,
+the mapped pages are marked as not present. Any access to the pages causes a
+fault. The page fault handler calls mmiotrace to handle the fault. Mmiotrace
+marks the page present, sets TF flag to achieve single stepping and exits the
+fault handler. The instruction that faulted is executed and debug trap is
+entered. Here mmiotrace again marks the page as not present. The instruction
+is decoded to get the type of operation (read/write), data width and the value
+read or written. These are stored to the trace log.
+
+Setting the page present in the page fault handler has a race condition on SMP
+machines. During the single stepping other CPUs may run freely on that page
+and events can be missed without a notice. Re-enabling other CPUs during
+tracing is discouraged.
+
+
+Trace Log Format
+----------------
+
+The raw log is text and easily filtered with e.g. grep and awk. One record is
+one line in the log. A record starts with a keyword, followed by keyword
+dependant arguments. Arguments are separated by a space, or continue until the
+end of line. The format for version 20070824 is as follows:
+
+Explanation Keyword Space separated arguments
+---------------------------------------------------------------------------
+
+read event R width, timestamp, map id, physical, value, PC, PID
+write event W width, timestamp, map id, physical, value, PC, PID
+ioremap event MAP timestamp, map id, physical, virtual, length, PC, PID
+iounmap event UNMAP timestamp, map id, PC, PID
+marker MARK timestamp, text
+version VERSION the string "20070824"
+info for reader LSPCI one line from lspci -v
+PCI address map PCIDEV space separated /proc/bus/pci/devices data
+unk. opcode UNKNOWN timestamp, map id, physical, data, PC, PID
+
+Timestamp is in seconds with decimals. Physical is a PCI bus address, virtual
+is a kernel virtual address. Width is the data width in bytes and value is the
+data value. Map id is an arbitrary id number identifying the mapping that was
+used in an operation. PC is the program counter and PID is process id. PC is
+zero if it is not recorded. PID is always zero as tracing MMIO accesses
+originating in user space memory is not yet supported.
+
+For instance, the following awk filter will pass all 32-bit writes that target
+physical addresses in the range [0xfb73ce40, 0xfb800000[
+
+$ awk '/W 4 / { adr=strtonum($5); if (adr >= 0xfb73ce40 &&
+adr < 0xfb800000) print; }'
+
+
+Tools for Developers
+--------------------
+
+The user space tools include utilities for:
+- replacing numeric addresses and values with hardware register names
+- replaying MMIO logs, i.e., re-executing the recorded writes

+
+
+ Introduction
+
+UWB is a wide-band communication protocol that is to serve also as the
+low-level protocol for others (much like TCP sits on IP). Currently
+these others are Wireless USB and TCP/IP, but seems Bluetooth and
+Firewire/1394 are coming along.
+
+UWB uses a band from roughly 3 to 10 GHz, transmitting at a max of
+~-41dB (or 0.074 uW/MHz--geography specific data is still being
+negotiated w/ regulators, so watch for changes). That band is divided in
+a bunch of ~1.5 GHz wide channels (or band groups) composed of three
+subbands/subchannels (528 MHz each). Each channel is independent of each
+other, so you could consider them different "busses". Initially this
+driver considers them all a single one.
+
+Radio time is divided in 65536 us long /superframes/, each one divided
+in 256 256us long /MASs/ (Media Allocation Slots), which are the basic
+time/media allocation units for transferring data. At the beginning of
+each superframe there is a Beacon Period (BP), where every device
+transmit its beacon on a single MAS. The length of the BP depends on how
+many devices are present and the length of their beacons.
+
+Devices have a MAC (fixed, 48 bit address) and a device (changeable, 16
+bit address) and send periodic beacons to advertise themselves and pass
+info on what they are and do. They advertise their capabilities and a
+bunch of other stuff.
+
+The different logical parts of this driver are:
+
+ *
+
+ *UWB*: the Ultra-Wide-Band stack -- manages the radio and
+ associated spectrum to allow for devices sharing it. Allows to
+ control bandwidth assingment, beaconing, scanning, etc
+
+ *
+
+ *WUSB*: the layer that sits on top of UWB to provide Wireless USB.
+ The Wireless USB spec defines means to control a UWB radio and to
+ do the actual WUSB.
+
+
+ HWA: Host Wire adapters, your Wireless USB dongle
+
+WUSB also defines a device called a Host Wire Adaptor (HWA), which in
+mere terms is a USB dongle that enables your PC to have UWB and Wireless
+USB. The Wireless USB Host Controller in a HWA looks to the host like a
+[Wireless] USB controller connected via USB (!)
+
+The HWA itself is broken in two or three main interfaces:
+
+ *
+
+ *RC*: Radio control -- this implements an interface to the
+ Ultra-Wide-Band radio controller. The driver for this implements a
+ USB-based UWB Radio Controller to the UWB stack.
+
+ *
+
+ *HC*: the wireless USB host controller. It looks like a USB host
+ whose root port is the radio and the WUSB devices connect to it.
+ To the system it looks like a separate USB host. The driver (will)
+ implement a USB host controller (similar to UHCI, OHCI or EHCI)
+ for which the root hub is the radio...To reiterate: it is a USB
+ controller that is connected via USB instead of PCI.
+
+ *
+
+ *WINET*: some HW provide a WiNET interface (IP over UWB). This
+ package provides a driver for it (it looks like a network
+ interface, winetX). The driver detects when there is a link up for
+ their type and kick into gear.
+
+
+ DWA: Device Wired Adaptor, a Wireless USB hub for wired devices
+
+These are the complement to HWAs. They are a USB host for connecting
+wired devices, but it is connected to your PC connected via Wireless
+USB. To the system it looks like yet another USB host. To the untrained
+eye, it looks like a hub that connects upstream wirelessly.
+
+We still offer no support for this; however, it should share a lot of
+code with the HWA-RC driver; there is a bunch of factorization work that
+has been done to support that in upcoming releases.
+
+
+ WHCI: Wireless Host Controller Interface, the PCI WUSB host adapter
+
+This is your usual PCI device that implements WHCI. Similar in concept
+to EHCI, it allows your wireless USB devices (including DWAs) to connect
+to your host via a PCI interface. As in the case of the HWA, it has a
+Radio Control interface and the WUSB Host Controller interface per se.
+
+There is still no driver support for this, but will be in upcoming
+releases.
+
+
+ The UWB stack
+
+The main mission of the UWB stack is to keep a tally of which devices
+are in radio proximity to allow drivers to connect to them. As well, it
+provides an API for controlling the local radio controllers (RCs from
+now on), such as to start/stop beaconing, scan, allocate bandwidth, etc.
+
+
+ Devices and hosts: the basic structure
+
+The main building block here is the UWB device (struct uwb_dev). For
+each device that pops up in radio presence (ie: the UWB host receives a
+beacon from it) you get a struct uwb_dev that will show up in
+/sys/class/uwb and in /sys/bus/uwb/devices.
+
+For each RC that is detected, a new struct uwb_rc is created. In turn, a
+RC is also a device, so they also show in /sys/class/uwb and
+/sys/bus/uwb/devices, but at the same time, only radio controllers show
+up in /sys/class/uwb_rc.
+
+ *
+
+ [*] The reason for RCs being also devices is that not only we can
+ see them while enumerating the system device tree, but also on the
+ radio (their beacons and stuff), so the handling has to be
+ likewise to that of a device.
+
+Each RC driver is implemented by a separate driver that plugs into the
+interface that the UWB stack provides through a struct uwb_rc_ops. The
+spec creators have been nice enough to make the message format the same
+for HWA and WHCI RCs, so the driver is really a very thin transport that
+moves the requests from the UWB API to the device [/uwb_rc_ops->cmd()/]
+and sends the replies and notifications back to the API
+[/uwb_rc_neh_grok()/]. Notifications are handled to the UWB daemon, that
+is chartered, among other things, to keep the tab of how the UWB radio
+neighborhood looks, creating and destroying devices as they show up or
+dissapear.
+
+Command execution is very simple: a command block is sent and a event
+block or reply is expected back. For sending/receiving command/events, a
+handle called /neh/ (Notification/Event Handle) is opened with
+/uwb_rc_neh_open()/.
+
+The HWA-RC (USB dongle) driver (drivers/uwb/hwa-rc.c) does this job for
+the USB connected HWA. Eventually, drivers/whci-rc.c will do the same
+for the PCI connected WHCI controller.
+
+
+ Host Controller life cycle
+
+So let's say we connect a dongle to the system: it is detected and
+firmware uploaded if needed [for Intel's i1480
+/drivers/uwb/ptc/usb.c:ptc_usb_probe()/] and then it is reenumerated.
+Now we have a real HWA device connected and
+/drivers/uwb/hwa-rc.c:hwarc_probe()/ picks it up, that will set up the
+Wire-Adaptor environment and then suck it into the UWB stack's vision of
+the world [/drivers/uwb/lc-rc.c:uwb_rc_add()/].
+
+ *
+
+ [*] The stack should put a new RC to scan for devices
+ [/uwb_rc_scan()/] so it finds what's available around and tries to
+ connect to them, but this is policy stuff and should be driven
+ from user space. As of now, the operator is expected to do it
+ manually; see the release notes for documentation on the procedure.
+
+When a dongle is disconnected, /drivers/uwb/hwa-rc.c:hwarc_disconnect()/
+takes time of tearing everything down safely (or not...).
+
+
+ On the air: beacons and enumerating the radio neighborhood
+
+So assuming we have devices and we have agreed for a channel to connect
+on (let's say 9), we put the new RC to beacon:
+
+ *
+
+ $ echo 9 0 > /sys/class/uwb_rc/uwb0/beacon
+
+Now it is visible. If there were other devices in the same radio channel
+and beacon group (that's what the zero is for), the dongle's radio
+control interface will send beacon notifications on its
+notification/event endpoint (NEEP). The beacon notifications are part of
+the event stream that is funneled into the API with
+/drivers/uwb/neh.c:uwb_rc_neh_grok()/ and delivered to the UWBD, the UWB
+daemon through a notification list.
+
+UWBD wakes up and scans the event list; finds a beacon and adds it to
+the BEACON CACHE (/uwb_beca/). If he receives a number of beacons from
+the same device, he considers it to be 'onair' and creates a new device
+[/drivers/uwb/lc-dev.c:uwbd_dev_onair()/]. Similarly, when no beacons
+are received in some time, the device is considered gone and wiped out
+[uwbd calls periodically /uwb/beacon.c:uwb_beca_purge()/ that will purge
+the beacon cache of dead devices].
+
+
+ Device lists
+
+All UWB devices are kept in the list of the struct bus_type uwb_bus.
+
+
+ Bandwidth allocation
+
+The UWB stack maintains a local copy of DRP availability through
+processing of incoming *DRP Availability Change* notifications. This
+local copy is currently used to present the current bandwidth
+availability to the user through the sysfs file
+/sys/class/uwb_rc/uwbx/bw_avail. In the future the bandwidth
+availability information will be used by the bandwidth reservation
+routines.
+
+The bandwidth reservation routines are in progress and are thus not
+present in the current release. When completed they will enable a user
+to initiate DRP reservation requests through interaction with sysfs. DRP
+reservation requests from remote UWB devices will also be handled. The
+bandwidth management done by the UWB stack will include callbacks to the
+higher layers will enable the higher layers to use the reservations upon
+completion. [Note: The bandwidth reservation work is in progress and
+subject to change.]
+
+
+ Wireless USB Host Controller drivers
+
+*WARNING* This section needs a lot of work!
+
+As explained above, there are three different types of HCs in the WUSB
+world: HWA-HC, DWA-HC and WHCI-HC.
+
+HWA-HC and DWA-HC share that they are Wire-Adapters (USB or WUSB
+connected controllers), and their transfer management system is almost
+identical. So is their notification delivery system.
+
+HWA-HC and WHCI-HC share that they are both WUSB host controllers, so
+they have to deal with WUSB device life cycle and maintenance, wireless
+root-hub
+
+HWA exposes a Host Controller interface (HWA-HC 0xe0/02/02). This has
+three endpoints (Notifications, Data Transfer In and Data Transfer
+Out--known as NEP, DTI and DTO in the code).
+
+We reserve UWB bandwidth for our Wireless USB Cluster, create a Cluster
+ID and tell the HC to use all that. Then we start it. This means the HC
+starts sending MMCs.
+
+ *
+
+ The MMCs are blocks of data defined somewhere in the WUSB1.0 spec
+ that define a stream in the UWB channel time allocated for sending
+ WUSB IEs (host to device commands/notifications) and Device
+ Notifications (device initiated to host). Each host defines a
+ unique Wireless USB cluster through MMCs. Devices can connect to a
+ single cluster at the time. The IEs are Information Elements, and
+ among them are the bandwidth allocations that tell each device
+ when can they transmit or receive.
+
+Now it all depends on external stimuli.
+
+*New device connection*
+
+A new device pops up, it scans the radio looking for MMCs that give out
+the existence of Wireless USB channels. Once one (or more) are found,
+selects which one to connect to. Sends a /DN_Connect/ (device
+notification connect) during the DNTS (Device Notification Time
+Slot--announced in the MMCs
+
+HC picks the /DN_Connect/ out (nep module sends to notif.c for delivery
+into /devconnect/). This process starts the authentication process for
+the device. First we allocate a /fake port/ and assign an
+unauthenticated address (128 to 255--what we really do is
+0x80 | fake_port_idx). We fiddle with the fake port status and /khubd/
+sees a new connection, so he moves on to enable the fake port with a reset.
+
+So now we are in the reset path -- we know we have a non-yet enumerated
+device with an unauthorized address; we ask user space to authenticate
+(FIXME: not yet done, similar to bluetooth pairing), then we do the key
+exchange (FIXME: not yet done) and issue a /set address 0/ to bring the
+device to the default state. Device is authenticated.
+
+From here, the USB stack takes control through the usb_hcd ops. khubd
+has seen the port status changes, as we have been toggling them. It will
+start enumerating and doing transfers through usb_hcd->urb_enqueue() to
+read descriptors and move our data.
+
+*Device life cycle and keep alives*
+
+Everytime there is a succesful transfer to/from a device, we update a
+per-device activity timestamp. If not, every now and then we check and
+if the activity timestamp gets old, we ping the device by sending it a
+Keep Alive IE; it responds with a /DN_Alive/ pong during the DNTS (this
+arrives to us as a notification through
+devconnect.c:wusb_handle_dn_alive(). If a device times out, we
+disconnect it from the system (cleaning up internal information and
+toggling the bits in the fake hub port, which kicks khubd into removing
+the rest of the stuff).
+
+This is done through devconnect:__wusb_check_devs(), which will scan the
+device list looking for whom needs refreshing.
+
+If the device wants to disconnect, it will either die (ugly) or send a
+/DN_Disconnect/ that will prompt a disconnection from the system.
+
+*Sending and receiving data*
+
+Data is sent and received through /Remote Pipes/ (rpipes). An rpipe is
+/aimed/ at an endpoint in a WUSB device. This is the same for HWAs and
+DWAs.
+
+Each HC has a number of rpipes and buffers that can be assigned to them;
+when doing a data transfer (xfer), first the rpipe has to be aimed and
+prepared (buffers assigned), then we can start queueing requests for
+data in or out.
+
+Data buffers have to be segmented out before sending--so we send first a
+header (segment request) and then if there is any data, a data buffer
+immediately after to the DTI interface (yep, even the request). If our
+buffer is bigger than the max segment size, then we just do multiple
+requests.
+
+[This sucks, because doing USB scatter gatter in Linux is resource
+intensive, if any...not that the current approach is not. It just has to
+be cleaned up a lot :)].
+
+If reading, we don't send data buffers, just the segment headers saying
+we want to read segments.
+
+When the xfer is executed, we receive a notification that says data is
+ready in the DTI endpoint (handled through
+xfer.c:wa_handle_notif_xfer()). In there we read from the DTI endpoint a
+descriptor that gives us the status of the transfer, its identification
+(given when we issued it) and the segment number. If it was a data read,
+we issue another URB to read into the destination buffer the chunk of
+data coming out of the remote endpoint. Done, wait for the next guy. The
+callbacks for the URBs issued from here are the ones that will declare
+the xfer complete at some point and call it's callback.
+
+Seems simple, but the implementation is not trivial.
+
+ *
+
+ *WARNING* Old!!
+
+The main xfer descriptor, wa_xfer (equivalent to a URB) contains an
+array of segments, tallys on segments and buffers and callback
+information. Buried in there is a lot of URBs for executing the segments
+and buffer transfers.
+
+For OUT xfers, there is an array of segments, one URB for each, another
+one of buffer URB. When submitting, we submit URBs for segment request
+1, buffer 1, segment 2, buffer 2...etc. Then we wait on the DTI for xfer
+result data; when all the segments are complete, we call the callback to
+finalize the transfer.
+
+For IN xfers, we only issue URBs for the segments we want to read and
+then wait for the xfer result data.
+
+*URB mapping into xfers*
+
+This is done by hwahc_op_urb_[en|de]queue(). In enqueue() we aim an
+rpipe to the endpoint where we have to transmit, create a transfer
+context (wa_xfer) and submit it. When the xfer is done, our callback is
+called and we assign the status bits and release the xfer resources.
+
+In dequeue() we are basically cancelling/aborting the transfer. We issue
+a xfer abort request to the HC, cancell all the URBs we had submitted
+and not yet done and when all that is done, the xfer callback will be
+called--this will call the URB callback.

-
-This document and the new uhci sources can be found on
- http://hotswap.in.tum.de/usb
-
-1. General issues
-
-1.1 Why a new UHCI driver, we already have one?!?
-
-Correct, but its internal structure got more and more mixed up by the (still
-ongoing) efforts to get isochronous transfers (ISO) to work.
-Since there is an increasing need for reliable ISO-transfers (especially
-for USB-audio needed by TS and for a DAB-USB-Receiver build by GA and DF),
-this state was a bit unsatisfying in our opinion, so we've decided (based
-on knowledge and experiences with the old UHCI driver) to start
-from scratch with a new approach, much simpler but at the same time more
-powerful.
-It is inspired by the way Win98/Win2000 handles USB requests via URBs,
-but it's definitely 100% free of MS-code and doesn't crash while
-unplugging an used ISO-device like Win98 ;-)
-Some code for HW setup and root hub management was taken from the
-original UHCI driver, but heavily modified to fit into the new code.
-The invention of the basic concept, and major coding were completed in two
-days (and nights) on the 16th and 17th of October 1999, now known as the
-great USB-October-Revolution started by GA, DF, and TS ;-)
-
-Since the concept is in no way UHCI dependent, we hope that it will also be
-transferred to the OHCI-driver, so both drivers share a common API.
-
-1.2. Advantages and disadvantages
-
-+ All USB transfer types work now!
-+ Asynchronous operation
-+ Simple, but powerful interface (only two calls for start and cancel)
-+ Easy migration to the new API, simplified by a compatibility API
-+ Simple usage of ISO transfers
-+ Automatic linking of requests
-+ ISO transfers allow variable length for each frame and striping
-+ No CPU dependent and non-portable atomic memory access, no asm()-inlines
-+ Tested on x86 and Alpha
-
-- Rewriting for ISO transfers needed
-
-1.3. Is there some compatibility to the old API?
-
-Yes, but only for control, bulk and interrupt transfers. We've implemented
-some wrapper calls for these transfer types. The usbcore works fine with
-these wrappers. For ISO there's no compatibility, because the old ISO-API
-and its semantics were unnecessary complicated in our opinion.
-
-1.4. What's really working?
-
-As said above, CTRL and BULK already work fine even with the wrappers,
-so legacy code wouldn't notice the change.
-Regarding to Thomas, ISO transfers now run stable with USB audio.
-INT transfers (e.g. mouse driver) work fine, too.
-
-1.5. Are there any bugs?
-
-No ;-)
-Hm...
-Well, of course this implementation needs extensive testing on all available
-hardware, but we believe that any fixes shouldn't harm the overall concept.
-
-1.6. What should be done next?
-
-A large part of the request handling seems to be identical for UHCI and
-OHCI, so it would be a good idea to extract the common parts and have only
-the HW specific stuff in uhci.c. Furthermore, all other USB device drivers
-should need URBification, if they use isochronous or interrupt transfers.
-One thing missing in the current implementation (and the old UHCI driver)
-is fair queueing for BULK transfers. Since this would need (in principle)
-the alteration of already constructed TD chains (to switch from depth to
-breadth execution), another way has to be found. Maybe some simple
-heuristics work with the same effect.
-
----------------------------------------------------------------------------
-
-2. Internal structure and mechanisms
-
-To get quickly familiar with the internal structures, here's a short
-description how the new UHCI driver works. However, the ultimate source of
-truth is only uhci.c!
-
-2.1. Descriptor structure (QHs and TDs)
-
-During initialization, the following skeleton is allocated in init_skel:
-
- framespecific | common chain
-
-framelist[]
-[ 0 ]-----> TD --> TD -------\
-[ 1 ]-----> TD --> TD --------> TD ----> QH -------> QH -------> QH ---> NULL
- ... TD --> TD -------/
-[1023]-----> TD --> TD ------/
-
- ^^ ^^ ^^ ^^ ^^ ^^
- 1024 TDs for 7 TDs for 1 TD for Start of Start of End Chain
- ISO INT (2-128ms) 1ms-INT CTRL Chain BULK Chain
-
-For each CTRL or BULK transfer a new QH is allocated and the containing data
-transfers are appended as (vertical) TDs. After building the whole QH with its
-dangling TDs, the QH is inserted before the BULK Chain QH (for CTRL) or
-before the End Chain QH (for BULK). Since only the QH->next pointers are
-affected, no atomic memory operation is required. The three QHs in the
-common chain are never equipped with TDs!
-
-For ISO or INT, the TD for each frame is simply inserted into the appropriate
-ISO/INT-TD-chain for the desired frame. The 7 skeleton INT-TDs are scattered
-among the 1024 frames similar to the old UHCI driver.
-
-For CTRL/BULK/ISO, the last TD in the transfer has the IOC-bit set. For INT,
-every TD (there is only one...) has the IOC-bit set.
-
-Besides the data for the UHCI controller (2 or 4 32bit words), the descriptors
-are double-linked through the .vertical and .horizontal elements in the
-SW data of the descriptor (using the double-linked list structures and
-operations), but SW-linking occurs only in closed domains, i.e. for each of
-the 1024 ISO-chains and the 8 INT-chains there is a closed cycle. This
-simplifies all insertions and unlinking operations and avoids costly
-bus_to_virt()-calls.
-
-2.2. URB structure and linking to QH/TDs
-
-During assembly of the QH and TDs of the requested action, these descriptors
-are stored in urb->urb_list, so the allocated QH/TD descriptors are bound to
-this URB.
-If the assembly was successful and the descriptors were added to the HW chain,
-the corresponding URB is inserted into a global URB list for this controller.
-This list stores all pending URBs.
-
-2.3. Interrupt processing
-
-Since UHCI provides no means to directly detect completed transactions, the
-following is done in each UHCI interrupt (uhci_interrupt()):
-
-For each URB in the pending queue (process_urb()), the ACTIVE-flag of the
-associated TDs are processed (depending on the transfer type
-process_{transfer|interrupt|iso}()). If the TDs are not active anymore,
-they indicate the completion of the transaction and the status is calculated.
-Inactive QH/TDs are removed from the HW chain (since the host controller
-already removed the TDs from the QH, no atomic access is needed) and
-eventually the URB is marked as completed (OK or errors) and removed from the
-pending queue. Then the next linked URB is submitted. After (or immediately
-before) that, the completion handler is called.
-
-2.4. Unlinking URBs
-
-First, all QH/TDs stored in the URB are unlinked from the HW chain.
-To ensure that the host controller really left a vertical TD chain, we
-wait for one frame. After that, the TDs are physically destroyed.
-
-2.5. URB linking and the consequences
-
-Since URBs can be linked and the corresponding submit_urb is called in
-the UHCI-interrupt, all work associated with URB/QH/TD assembly has to be
-interrupt save. This forces kmalloc to use GFP_ATOMIC in the interrupt.

+pagemap, from the userspace perspective
+---------------------------------------
+
+pagemap is a new (as of 2.6.25) set of interfaces in the kernel that allow
+userspace programs to examine the page tables and related information by
+reading files in /proc.
+
+There are three components to pagemap:
+
+ * /proc/pid/pagemap. This file lets a userspace process find out which
+ physical frame each virtual page is mapped to. It contains one 64-bit
+ value for each virtual page, containing the following data (from
+ fs/proc/task_mmu.c, above pagemap_read):
+
+ * Bits 0-55 page frame number (PFN) if present
+ * Bits 0-4 swap type if swapped
+ * Bits 5-55 swap offset if swapped
+ * Bits 55-60 page shift (page size = 1<<page shift)
+ * Bit 61 reserved for future use
+ * Bit 62 page swapped
+ * Bit 63 page present
+
+ If the page is not present but in swap, then the PFN contains an
+ encoding of the swap file number and the page's offset into the
+ swap. Unmapped pages return a null PFN. This allows determining
+ precisely which pages are mapped (or in swap) and comparing mapped
+ pages between processes.
+
+ Efficient users of this interface will use /proc/pid/maps to
+ determine which areas of memory are actually mapped and llseek to
+ skip over unmapped regions.
+
+ * /proc/kpagecount. This file contains a 64-bit count of the number of
+ times each page is mapped, indexed by PFN.
+
+ * /proc/kpageflags. This file contains a 64-bit set of flags for each
+ page, indexed by PFN.
+
+ The flags are (from fs/proc/proc_misc, above kpageflags_read):
+
+ 0. LOCKED
+ 1. ERROR
+ 2. REFERENCED
+ 3. UPTODATE
+ 4. DIRTY
+ 5. LRU
+ 6. ACTIVE
+ 7. SLAB
+ 8. WRITEBACK
+ 9. RECLAIM
+ 10. BUDDY
+
+Using pagemap to do something useful:
+
+The general procedure for using pagemap to find out about a process' memory
+usage goes like this:
+
+ 1. Read /proc/pid/maps to determine which parts of the memory space are
+ mapped to what.
+ 2. Select the maps you are interested in -- all of them, or a particular
+ library, or the stack or the heap, etc.
+ 3. Open /proc/pid/pagemap and seek to the pages you would like to examine.
+ 4. Read a u64 for each page from pagemap.
+ 5. Open /proc/kpagecount and/or /proc/kpageflags. For each PFN you just
+ read, seek to that entry in the file, and read the data you want.
+
+For example, to find the "unique set size" (USS), which is the amount of
+memory that a process is using that is not shared with any other process,
+you can go through every map in the process, find the PFNs, look those up
+in kpagecount, and tally up the number of pages that are only referenced
+once.
+
+Other notes:
+
+Reading from any of the files will return -EINVAL if you are not starting
+the read on an 8-byte boundary (e.g., if you seeked an odd number of bytes
+into the file), or if the size of the read is not a multiple of 8 bytes.

- *
- * This version of the driver is somewhat selectable for the different

- * remainder is here.
- *
- * Buffer descriptors are kept in the CPM dual port RAM, and the frame
- * buffers are in the host memory.
- *
- * Right now, I am very watseful with the buffers. I allocate memory
- * pages and then divide them into 2K frame buffers. This way I know I
- * have buffers large enough to hold one frame within one buffer descriptor.
- * Once I get this working, I will use 64 or 128 byte CPM buffers, which
- * will be much more memory efficient and will easily handle lots of

- * Theory of Operation
- *
- * The MPC8260 CPM performs the Ethernet processing on an SCC. It can use
- * an aribtrary number of buffers on byte boundaries, but must have at
- * least two receive buffers to prevent constant overrun conditions.
- *
- * The buffer descriptors are allocated from the CPM dual port memory
- * with the data buffers allocated from host memory, just like all other
- * serial communication protocols. The host memory buffers are allocated
- * from the free page pool, and then divided into smaller receive and
- * transmit buffers. The size of the buffers should be a power of two,
- * since that nicely divides the page. This creates a ring buffer
- * structure similar to the LANCE and other controllers.
- *
- * Like the LANCE driver:
- * The driver runs as two independent, single-threaded flows of control. One
- * is the send-packet routine, which enforces single-threaded use by the
- * cep->tx_busy flag. The other thread is the interrupt handler, which is
- * single threaded by the hardware and other software.

- * Fast Ethernet Controller (FCC) driver for Motorola MPC8260.
- * Copyright (c) 2000 MontaVista Software, Inc. Dan Malek (dmalek@jlc.net)
- *
- * This version of the driver is a combination of the 8xx fec and
- * 8260 SCC Ethernet drivers. This version has some additional
- * configuration options, which should probably be moved out of
- * here. This driver currently works for the EST SBC8260,
- * SBS Diablo/BCM, Embedded Planet RPX6, TQM8260, and others.
- *
- * Right now, I am very watseful with the buffers. I allocate memory
- * pages and then divide them into 2K frame buffers. This way I know I
- * have buffers large enough to hold one frame within one buffer descriptor.
- * Once I get this working, I will use 64 or 128 byte CPM buffers, which
- * will be much more memory efficient and will easily handle lots of
- * small packets. Since this is a cache coherent processor and CPM,
- * I could also preallocate SKB's and use them directly on the interface.
- *
- * 2004-12 Leo Li (leoli@freescale.com)
- * - Rework the FCC clock configuration part, make it easier to configure.

- *
- * In addition to the individual control of the communication
- * channels, there are a few functions that globally affect the
- * communication processor.
- *
- * Buffer descriptors must be allocated from the dual ported memory
- * space. The allocator for that is here. When the communication
- * process is reset, we reclaim the memory available. There is
- * currently no deallocator for this memory.
- * The amount of space available is platform dependent. On the
- * MBX, the EPPC software loads additional microcode into the
- * communication processor, and uses some of the DP ram for this
- * purpose. Current, the first 512 bytes and the last 256 bytes of
- * memory are used. Right now I am conservative and only use the
- * memory that can never be used for microcode. If there are
- * applications that require more DP ram, we can expand the boundaries
- * but then we have to be careful of any downloaded microcode.

- * Ethernet driver for Motorola MPC8xx.
- * Copyright (c) 1997 Dan Malek (dmalek@jlc.net)
- *
- * I copied the basic skeleton from the lance driver, because I did not
- * know how to write the Linux driver, but I did know how the LANCE worked.
- *
- * This version of the driver is somewhat selectable for the different
- * processor/board combinations. It works for the boards I know about
- * now, and should be easily modified to include others. Some of the
- * configuration information is contained in <asm/cpm1.h> and the
- * remainder is here.
- *
- * Buffer descriptors are kept in the CPM dual port RAM, and the frame
- * buffers are in the host memory.
- *
- * Right now, I am very watseful with the buffers. I allocate memory
- * pages and then divide them into 2K frame buffers. This way I know I
- * have buffers large enough to hold one frame within one buffer descriptor.
- * Once I get this working, I will use 64 or 128 byte CPM buffers, which
- * will be much more memory efficient and will easily handle lots of
- * small packets.

- * Theory of Operation
- *
- * The MPC8xx CPM performs the Ethernet processing on SCC1. It can use
- * an aribtrary number of buffers on byte boundaries, but must have at
- * least two receive buffers to prevent constant overrun conditions.
- *
- * The buffer descriptors are allocated from the CPM dual port memory
- * with the data buffers allocated from host memory, just like all other
- * serial communication protocols. The host memory buffers are allocated
- * from the free page pool, and then divided into smaller receive and
- * transmit buffers. The size of the buffers should be a power of two,
- * since that nicely divides the page. This creates a ring buffer
- * structure similar to the LANCE and other controllers.
- *
- * Like the LANCE driver:
- * The driver runs as two independent, single-threaded flows of control. One
- * is the send-packet routine, which enforces single-threaded use by the
- * cep->tx_busy flag. The other thread is the interrupt handler, which is
- * single threaded by the hardware and other software.
- *
- * The send packet thread has partial control over the Tx ring and the
- * 'cep->tx_busy' flag. It sets the tx_busy flag whenever it's queuing a Tx
- * packet. If the next queue slot is empty, it clears the tx_busy flag when
- * finished otherwise it sets the 'lp->tx_full' flag.
- *
- * The MBX has a control register external to the MPC8xx that has some
- * control of the Ethernet interface. Information is in the manual for
- * your board.
- *
- * The RPX boards have an external control/status register. Consult the
- * programming documents for details unique to your board.
- *
- * For the TQM8xx(L) modules, there is no control register interface.
- * All functions are directly controlled using I/O pins. See <asm/cpm1.h>.

- * Fast Ethernet Controller (FEC) driver for Motorola MPC8xx.
- * Copyright (c) 1997 Dan Malek (dmalek@jlc.net)
- *
- * This version of the driver is specific to the FADS implementation,
- * since the board contains control registers external to the processor
- * for the control of the LevelOne LXT970 transceiver. The MPC860T manual
- * describes connections using the internal parallel port I/O, which
- * is basically all of Port D.
- *
- * Includes support for the following PHYs: QS6612, LXT970, LXT971/2.
- *
- * Right now, I am very wasteful with the buffers. I allocate memory
- * pages and then divide them into 2K frame buffers. This way I know I
- * have buffers large enough to hold one frame within one buffer descriptor.
- * Once I get this working, I will use 64 or 128 byte CPM buffers, which
- * will be much more memory efficient and will easily handle lots of
- * small packets.
- *
- * Much better multiple PHY support by Magnus Damm.
- * Copyright (c) 2000 Ericsson Radio Systems AB.
- *
- * Make use of MII for PHY control configurable.
- * Some fixes.
- * Copyright (c) 2000-2002 Wolfgang Denk, DENX Software Engineering.

-
- This option is only usefully if you have a processor that supports

-config TAU

- help
- G3 and G4 processors have an on-chip temperature sensor called the

- temperature within 2-4 degrees Celsius. This option shows the current
- on-die temperature in /proc/cpuinfo if the cpu supports it.
-
- Unfortunately, on some chip revisions, this sensor is very inaccurate
- and in some cases, does not work at all, so don't assume the cpu
- temp is actually what /proc/cpuinfo says it is.
-
-config TAU_INT
- bool "Interrupt driven TAU driver (DANGEROUS)"

- ---help---
- The TAU supports an interrupt driven mode which causes an interrupt
- whenever the temperature goes out of range. This is the fastest way
- to get notified the temp has exceeded a range. With this option off,
- a timer is used to re-check the temperature periodically.
-
- However, on some cpus it appears that the TAU interrupt hardware
- is buggy and can cause a situation which would lead unexplained hard
- lockups.
-
- Unless you are extending the TAU driver, or enjoy kernel/hardware
- debugging, leave this option off.
-
-config TAU_AVERAGE
- bool "Average high and low temp"

- ---help---
- The TAU hardware can compare the temperature to an upper and lower
- bound. The default behavior is to show both the upper and lower
- bound in /proc/cpuinfo. If the range is large, the temperature is
- either changing a lot, or the TAU hardware is broken (likely on some
- G4's). If the range is small (around 4 degrees), the temperature is
- relatively stable. If you say Y here, a single temperature value,
- halfway between the upper and lower bounds, will be reported in

- say Y here, the kernel will include code to emulate a floating-point
- unit, which will allow programs that use floating-point
- instructions to run.
-
- If you have an Apple machine or an IBM RS/6000 or pSeries machine,
- or any machine with a 6xx, 7xx or 7xxx series processor, say N

-config KEXEC
- bool "kexec system call (EXPERIMENTAL)"

- help
- kexec is a system call that implements the ability to shutdown your
- current kernel, and to start another kernel. It is like a reboot
- but it is independent of the system firmware. And like a reboot
- you can start any kernel with it, not just Linux.
-
- The name comes from the similarity to the exec system call.
-
- It is an ongoing process to be certain the hardware in a machine
- is properly shutdown, so do not be surprised if this code does not
- initially work for you. It may help to enable device hotplugging
- support. As of this writing the exact hardware interface is
- strongly in flux, so no good recommendation can be made.
-
- In the GameCube implementation, kexec allows you to load and
- run DOL files, including kernel and homebrew DOLs.

-# This is far from simple, but I couldn't think of a good name. This is
-# for making the 'zImage' or 'zImage.initrd' on a number of targets.
-#
-# Author: Tom Rini <trini@mvista.com>
-#
-# Notes:
-# (1) For machines that do not want to use the ELF image directly (including
-# stripping just the ELF header off), they must set the variables
-# zimage-$(CONFIG_MACHINE) and zimagerd-$(CONFIG_MACHINE) to the target
-# that produces the desired image and they must set end-$(CONFIG_MACHINE)
-# to what will be suffixed to the image filename.
-# (2) Regardless of (1), to have the resulting image be something other
-# than 'zImage.elf', set end-$(CONFIG_MACHINE) to be the suffix used for
-# the zImage, znetboot, and znetbootrd targets.
-# (3) For machine targets which use the mktree program, you can optionally
-# set entrypoint-$(CONFIG_MACHINE) to the location which the image should be
-# loaded at. The optimal setting for entrypoint-$(CONFIG_MACHINE) is the link
-# address.
-# (4) It is advisable to pass in the memory size using BI_MEMSIZE and
-# get_mem_size(), which is memory controller dependent. Add in the correct
-# XXX_memory.o file for this to work, as well as editing the
-# misc-$(CONFIG_MACHINE) variable.

- * When reading the configuration space, if something does not respond
- * the bus times out and we get a machine check interrupt. So, the
- * good ol' exception tables come to mind to trap it and return some
- * value.
- *
- * On an error we just return a -1, since that is what the caller wants
- * returned if nothing is present. I copied this from __get_user_asm,
- * with the only difference of returning -1 instead of EFAULT.
- * There is an associated hack in the machine check trap code.
- *
- * The QSPAN is also a big endian device, that is it makes the PCI
- * look big endian to us. This presents a problem for the Linux PCI
- * functions, which assume little endian. For example, we see the
- * first 32-bit word like this:
- * ------------------------
- * | Device ID | Vendor ID |
- * ------------------------
- * If we read/write as a double word, that's OK. But in our world,
- * when read as a word, device ID is at location 0, not location 2 as
- * the little endian PCI would believe. We have to switch bits in
- * the PCI addresses given to us to get the data to/from the correct
- * byte lanes.
- *
- * The QSPAN only supports 4 bits of "slot" in the dev_fn instead of 5.
- * It always forces the MS bit to zero. Therefore, dev_fn values
- * greater than 128 are returned as "no device found" errors.
- *
- * The QSPAN can only perform long word (32-bit) configuration cycles.
- * The "offset" must have the two LS bits set to zero. Read operations
- * require we read the entire word and then sort out what should be
- * returned. Write operations other than long word require that we
- * read the long word, update the proper word or byte, then write the
- * entire long word back.
- *
- * PCI Bridge hack. We assume (correctly) that bus 0 is the primary
- * PCI bus from the QSPAN. If we are called with a bus number other
- * than zero, we create a Type 1 configuration access that a downstream
- * PCI bridge will interpret.

-/* MPC8xx
- * This port was done on an MBX board with an 860. Right now I only
- * support an ELF compressed (zImage) boot from EPPC-Bug because the
- * code there loads up some registers before calling us:
- * r3: ptr to board info data
- * r4: initrd_start or if no initrd then 0
- * r5: initrd_end - unused if r4 is 0
- * r6: Start of command line string
- * r7: End of command line string
- *
- * I decided to use conditional compilation instead of checking PVR and
- * adding more processor specific branches around code I don't need.
- * Since this is an embedded processor, I also appreciate any memory
- * savings I can get.
- *
- * The MPC8xx does not have any BATs, but it supports large page sizes.
- * We first initialize the MMU to support 8M byte pages, then load one
- * entry into each of the instruction and data TLBs to map the first
- * 8M 1:1. I also mapped an additional I/O space 1:1 so we can get to
- * the "internal" processor registers before MMU_init is called.
- *
- * The TLB code currently contains a major hack. Since I use the condition
- * code register, I have to save and restore it. I am out of registers, so
- * I just store it in memory location 0 (the TLB handlers are not reentrant).
- * To avoid making any decisions, I need to use the "segment" valid bit
- * in the first level table, but that would require many changes to the
- * Linux page directory/table functions that I don't want to do right now.
- *
- * I used to use SPRG2 for a temporary register in the TLB handler, but it
- * has since been put to other uses. I now use a hack to save a register
- * and the CCR at memory location 0.....Someday I'll fix this.....

- *
- * Our solution:
- * (1) Allocate resources for all buses behind PCI-to-PCI bridges.
- * This gives us fixed barriers on where we can allocate.
- * (2) Allocate resources for all enabled devices. If there is
- * a collision, just mark the resource as unallocated. Also
- * disable expansion ROMs during this step.
- * (3) Try to allocate resources for disabled devices. If the
- * resources were assigned correctly, everything goes well,
- * if they weren't, they won't disturb allocation of other
- * resources.

- * Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
- *
- * Module name: remcom.c $
- * Revision: 1.34 $
- * Date: 91/03/09 12:29:49 $
- * Contributor: Lake Stevens Instrument Division$
- *
- * Description: low level support for gdb debugger. $
- *
- * Considerations: only works on target hardware $
- *
- * Written by: Glenn Engel $
- * ModuleState: Experimental $
- *
- * NOTES: See Below $
- *
- * Modified for SPARC by Stu Grossman, Cygnus Support.
- *
- * This code has been extensively tested on the Fujitsu SPARClite demo board.
- *
- * To enable debugger support, two things need to happen. One, a
- * call to set_debug_traps() is necessary in order to allow any breakpoints
- * or error conditions to be properly intercepted and reported to gdb.
- * Two, a breakpoint needs to be generated to begin communication. This
- * is most easily accomplished by a call to breakpoint(). Breakpoint()
- * simulates a breakpoint by executing a trap #1.
- *
- *************
- *
- * The following gdb commands are supported:
- *
- * command function Return value
- *
- * g return the value of the CPU registers hex data or ENN
- * G set the value of the CPU registers OK or ENN
- * qOffsets Get section offsets. Reply is Text=xxx;Data=yyy;Bss=zzz
- *
- * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
- * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
- *
- * c Resume at current address SNN ( signal NN)
- * cAA..AA Continue at address AA..AA SNN
- *
- * s Step one instruction SNN
- * sAA..AA Step one instruction from AA..AA SNN
- *
- * k kill
- *
- * ? What was the last sigval ? SNN (signal NN)
- *
- * bBB..BB Set baud rate to BB..BB OK or BNN, then sets
- * baud rate
- *
- * All commands and responses are sent with a packet which includes a
- * checksum. A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum> :: <two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.
- * '+' indicates a successful transfer. '-' indicates a failed transfer.
- *
- * Example:
- *
- * Host: Reply:
- * $m0,10#2a +$00010203040506070809101112131415#42

- * Common time routines among all ppc machines.

- * Written by Cort Dougan (cort@cs.nmt.edu) to merge
- * Paul Mackerras' version and mine for PReP and Pmac.
- * MPC8xx/MBX changes by Dan Malek (dmalek@jlc.net).
- *
- * First round of bugfixes by Gabriel Paubert (paubert@iram.es)
- * to make clock more stable (2.4.0-test5). The only thing
- * that this code assumes is that the timebases have been synchronized
- * by firmware on SMP and are never stopped (never do sleep
- * on SMP then, nap and doze are OK).
- *
- * TODO (not necessarily in this file):
- * - improve precision and reproducibility of timebase frequency
- * measurement at boot time.
- * - get rid of xtime_lock for gettimeofday (generic kernel problem
- * to be implemented on all architectures for SMP scalability and
- * eventually implementing gettimeofday without entering the kernel).
- * - put all time/clock related variables in a single structure
- * to minimize number of cache lines touched by gettimeofday()
- * - for astronomical applications: add a new function to get
- * non ambiguous timestamps even around leap seconds. This needs
- * a new timestamp format and a good name.
- *
- *
- * The following comment is partially obsolete (at least the long wait
- * is no more a valid reason):
- * Since the MPC8xx has a programmable interrupt timer, I decided to
- * use that rather than the decrementer. Two reasons: 1.) the clock
- * frequency is low, causing 2.) a long wait in the timer interrupt
- * while ((d = get_dec()) == dval)
- * loop. The MPC8xx can be driven from a variety of input clocks,
- * so a number of assumptions have been made here because the kernel
- * parameter HZ is a constant. We assume (correctly, today :-) that
- * the MPC8xx on the MBX board is driven from a 32.768 kHz crystal.
- * This is then divided by 4, providing a 8192 Hz clock into the PIT.
- * Since it is not possible to get a nice 100 Hz clock out of this, without
- * creating a software PLL, I have set HZ to 128. -- Dan
- *
- * 1997-09-10 Updated NTP code according to technical memorandum Jan '96

- * This file adds support for the Motorola SPS Sandpoint Test Platform.
- * These boards have a PPMC slot for the processor so any combination
- * of cpu and host bridge can be attached. This port is for an 8240 PPMC
- * module from Motorola SPS and other closely related cpu/host bridge
- * combinations (e.g., 750/755/7400 with MPC107 host bridge).
- * The sandpoint itself has a Windbond 83c553 (PCI-ISA bridge, 2 DMA ctlrs, 2
- * cascaded 8259 interrupt ctlrs, 8254 Timer/Counter, and an IDE ctlr), a
- * National 87308 (RTC, 2 UARTs, Keyboard & mouse ctlrs, and a floppy ctlr),
- * and 4 PCI slots (only 2 of which are usable; the other 2 are keyed for 3.3V
- * but are really 5V).
- *
- * The firmware on the sandpoint is called DINK (not my acronym :). This port
- * depends on DINK to do some basic initialization (e.g., initialize the memory
- * ctlr) and to ensure that the processor is using MAP B (CHRP map).
- *
- * The switch settings for the Sandpoint board MUST be as follows:
- * S3: down
- * S4: up
- * S5: up
- * S6: down
- *
- * 'down' is in the direction from the PCI slots towards the PPMC slot;
- * 'up' is in the direction from the PPMC slot towards the PCI slots.
- * Be careful, the way the sandpoint board is installed in XT chasses will
- * make the directions reversed.
- *
- * Since Motorola listened to our suggestions for improvement, we now have
- * the Sandpoint X3 board. All of the PCI slots are available, it uses
- * the serial interrupt interface (just a hardware thing we need to
- * configure properly).
- *
- * Use the default X3 switch settings. The interrupts are then:
- * EPIC Source
- * 0 SIOINT (8259, active low)
- * 1 PCI #1
- * 2 PCI #2
- * 3 PCI #3
- * 4 PCI #4
- * 7 Winbond INTC (IDE interrupt)
- * 8 Winbond INTD (IDE interrupt)
- *
- *
- * Motorola has finally released a version of DINK32 that correctly
- * (seemingly) initializes the memory controller correctly, regardless
- * of the amount of memory in the system. Once a method of determining
- * what version of DINK initializes the system for us, if applicable, is
- * found, we can hopefully stop hardcoding 32MB of RAM.

- * Workaround for device erratum PCI 9.

- * The erratum applies to all 8260 family Hip4 processors. It is scheduled

- * inbound write transaction and PCI outbound read transaction can result in a
- * bus deadlock. The suggested workaround is to use the IDMA controller to

- * OCP (On Chip Peripheral) is a software emulated "bus" with a
- * pseudo discovery method for dumb peripherals. Usually these type
- * of peripherals are found on embedded SoC (System On a Chip)
- * processors or highly integrated system controllers that have
- * a host bridge and many peripherals. Common examples where
- * this is already used include the PPC4xx, MPC52xx,
- * and MV64xxx parts.
- *
- * This subsystem creates a standard OCP bus type within the
- * device model. The devices on the OCP bus are seeded by an
- * an initial OCP device array created by the arch-specific
- * Device entries can be added/removed/modified through OCP
- * helper functions to accommodate system and board-specific
- * parameters commonly found in embedded systems. OCP also
- * provides a standard method for devices to describe extended
- * attributes about themselves to the system. A standard access
- * method allows OCP drivers to obtain the information, both
- * SoC-specific and system/board-specific, needed for operation.

- * of the transfers. Thus, enable_dma_interrupt()/disable_dma_interrupt() MUST
- * be called before calling alloc_dma_handle(). If the interrupt mode will never
- * change after powerup, then enable_dma_interrupt()/disable_dma_interrupt()
- * do not have to be called -- interrupts will be enabled or disabled based
- * on how the channel was configured after powerup by the hw_init_dma_channel()
- * function. Each sgl descriptor will be setup to interrupt if an error occurs;

- * This blows......
- * When reading the configuration space, if something does not respond
- * the bus times out and we get a machine check interrupt. So, the
- * good ol' exception tables come to mind to trap it and return some
- * value.
- *
- * On an error we just return a -1, since that is what the caller wants
- * returned if nothing is present. I copied this from __get_user_asm,
- * with the only difference of returning -1 instead of EFAULT.
- * There is an associated hack in the machine check trap code.
- *
- * The QSPAN is also a big endian device, that is it makes the PCI
- * look big endian to us. This presents a problem for the Linux PCI
- * functions, which assume little endian. For example, we see the
- * first 32-bit word like this:
- * ------------------------
- * | Device ID | Vendor ID |
- * ------------------------
- * If we read/write as a double word, that's OK. But in our world,
- * when read as a word, device ID is at location 0, not location 2 as
- * the little endian PCI would believe. We have to switch bits in
- * the PCI addresses given to us to get the data to/from the correct
- * byte lanes.
- *
- * The QSPAN only supports 4 bits of "slot" in the dev_fn instead of 5.
- * It always forces the MS bit to zero. Therefore, dev_fn values
- * greater than 128 are returned as "no device found" errors.
- *
- * The QSPAN can only perform long word (32-bit) configuration cycles.
- * The "offset" must have the two LS bits set to zero. Read operations
- * require we read the entire word and then sort out what should be
- * returned. Write operations other than long word require that we
- * read the long word, update the proper word or byte, then write the
- * entire long word back.
- *
- * PCI Bridge hack. We assume (correctly) that bus 0 is the primary
- * PCI bus from the QSPAN. If we are called with a bus number other
- * than zero, we create a Type 1 configuration access that a downstream
- * PCI bridge will interpret.

-/* ANSI and traditional C compatibility macros
-
- ANSI C is assumed if __STDC__ is #defined.
-
- Macro ANSI C definition Traditional C definition
- ----- ---- - ---------- ----------- - ----------
- PTR `void *' `char *'
- LONG_DOUBLE `long double' `double'
- VOLATILE `volatile' `'
- SIGNED `signed' `'
- PTRCONST `void *const' `char *'
- ANSI_PROTOTYPES 1 not defined
-
- CONST is also defined, but is obsolete. Just use const.
-
- DEFUN (name, arglist, args)
-
- Defines function NAME.
-
- ARGLIST lists the arguments, separated by commas and enclosed in
- parentheses. ARGLIST becomes the argument list in traditional C.
-
- ARGS list the arguments with their types. It becomes a prototype in
- ANSI C, and the type declarations in traditional C. Arguments should
- be separated with `AND'. For functions with a variable number of
- arguments, the last thing listed should be `DOTS'.
-
- DEFUN_VOID (name)
-
- Defines a function NAME, which takes no arguments.
-
- obsolete -- EXFUN (name, (prototype)) -- obsolete.
-
- Replaced by PARAMS. Do not use; will disappear someday soon.
- Was used in external function declarations.
- In ANSI C it is `NAME PROTOTYPE' (so PROTOTYPE should be enclosed in
- parentheses). In traditional C it is `NAME()'.
- For a function that takes no arguments, PROTOTYPE should be `(void)'.
-
- PARAMS ((args))
-
- We could use the EXFUN macro to handle prototype declarations, but
- the name is misleading and the result is ugly. So we just define a
- simple macro to handle the parameter lists, as in:
-
- static int foo PARAMS ((int, char));
-
- This produces: `static int foo();' or `static int foo (int, char);'
-
- EXFUN would have done it like this:
-
- static int EXFUN (foo, (int, char));
-
- but the function is not external...and it's hard to visually parse
- the function name out of the mess. EXFUN should be considered
- obsolete; new code should be written to use PARAMS.
-
- For example:
- extern int printf PARAMS ((CONST char *format DOTS));
- int DEFUN(fprintf, (stream, format),
- FILE *stream AND CONST char *format DOTS) { ... }
- void DEFUN_VOID(abort) { ... }

- 9-bit precision mode), and TelCom (now Microchip) TCN75.
-
- The DS75 and DS1775 in 10- to 12-bit precision modes will require

- precision anyhow.

+
+ - Dallas Semiconductor DS75 and DS1775
+ - Maxim MAX6625 and MAX6626
+ - Microchip MCP980x
+ - National Semiconductor LM75
+ - NXP's LM75A
+ - ST Microelectronics STDS75
+ - TelCom (now Microchip) TCN75
+ - Texas Instruments TMP100, TMP101, TMP75, TMP175, TMP275
+
+ This driver supports driver model based binding through board
+ specific I2C device tables.
+
+ It also supports the "legacy" style of driver binding. To use
+ that with some chips which don't replicate LM75 quirks exactly,
+ you may need the "force" module parameter.
This driver can also be built as a module. If so, the module
will be called lm75.

- This next batch of horrible preprocessor hackery is needed because the
- kernel's device_attribute mechanism fails to pass the actual
- attribute through to the show / store functions, which means we have no
- way to package up any attribute-specific parameters, like for example the
- control id. So we work around this brain-damage by encoding the control
- id into the show / store functions themselves and pick the function based
- on the control id we're setting up. These macros try to ease the pain.
- Yuck.

+ *
+ * Slots are uniquely identified by a @pci_bus, @slot_nr, @name tuple.
+ *
+ * Placeholder slots:
+ * In most cases, @pci_bus, @slot_nr will be sufficient to uniquely identify
+ * a slot. There is one notable exception - pSeries (rpaphp), where the
+ * @slot_nr cannot be determined until a device is actually inserted into
+ * the slot. In this scenario, the caller may pass -1 for @slot_nr.
+ *
+ * The following semantics are imposed when the caller passes @slot_nr ==
+ * -1. First, the check for existing %struct pci_slot is skipped, as the
+ * caller may know about several unpopulated slots on a given %struct
+ * pci_bus, and each slot would have a @slot_nr of -1. Uniqueness for
+ * these slots is then determined by the @name parameter. We expect
+ * kobject_init_and_add() to warn us if the caller attempts to create
+ * multiple slots with the same name. The other change in semantics is
+ * user-visible, which is the 'address' parameter presented in sysfs will
+ * consist solely of a dddd:bb tuple, where dddd is the PCI domain of the
+ * %struct pci_bus and bb is the bus number. In other words, the devfn of

+ * tcw and associated data. The data structures are contained inside a single
+ * contiguous buffer provided by the user.
+ *
+ * The itcw construction functions take care of overall data integrity:
+ * - reset unused fields to zero
+ * - fill in required pointers
+ * - ensure required alignment for data structures
+ * - prevent data structures to cross 4k-byte boundary where required
+ * - calculate tccb-related length fields
+ * - optionally provide ready-made interrogate tcw and associated structures
+ *
+ * Restrictions apply to the itcws created with these construction functions:
+ * - tida only supported for data address, not for tccb
+ * - only contiguous tidaw-lists (no ttic)
+ * - total number of bytes required per itcw may not exceed 4k bytes
+ * - either read or write operation (may not work with r=0 and w=0)
+ *
+ * Example:
+ * struct itcw *itcw;
+ * void *buffer;
+ * size_t size;
+ *
+ * size = itcw_calc_size(1, 2, 0);
+ * buffer = kmalloc(size, GFP_DMA);

+ * SOURCE/SINK FUNCTION ... a primary testing vehicle for USB peripheral
+ * controller drivers.
+ *
+ * This just sinks bulk packets OUT to the peripheral and sources them IN
+ * to the host, optionally with specific data patterns for integrity tests.
+ * As such it supports basic functionality and load tests.
+ *
+ * In terms of control messaging, this supports all the standard requests
+ * plus two that support control-OUT tests. If the optional "autoresume"
+ * mode is enabled, it provides good functional coverage for the "USBCV"
+ * test harness from USB-IF.
+ *
+ * Note that because this doesn't queue more than one request at a time,
+ * some other function must be used to test queueing logic. The network
+ * link (g_ether) is the best overall option for that, since its TX and RX
+ * queues are relatively independent, will receive a range of packet sizes,
+ * and can often be made to run out completely. Those issues are important
+ * when stress testing peripheral controller drivers.
+ *
+ *
+ * This is currently packaged as a configuration driver, which can't be
+ * combined with other functions to make composite devices. However, it
+ * can be combined with other independent configurations.

+ * This module encapsulates the TTY layer glue needed to provide basic
+ * "serial port" functionality through the USB gadget stack. Each such
+ * port is exposed through a /dev/ttyGS* node.
+ *
+ * After initialization (gserial_setup), these TTY port devices stay
+ * available until they are removed (gserial_cleanup). Each one may be
+ * connected to a USB function (gserial_connect), or disconnected (with
+ * gserial_disconnect) when the USB host issues a config change event.
+ * Data can only flow when the port is connected to the host.
+ *
+ * A given TTY port can be made available in multiple configurations.
+ * For example, each one might expose a ttyGS0 node which provides a
+ * login application. In one case that might use CDC ACM interface 0,
+ * while another configuration might use interface 3 for that. The
+ * work to handle that (including descriptor management) is not part
+ * of this module.
+ *
+ * Configurations may expose more than one TTY port. For example, if
+ * ttyGS0 provides login service, then ttyGS1 might provide dialer access
+ * for a telephone or fax link. And ttyGS2 might be something that just
+ * needs a simple byte stream interface for some messaging protocol that
+ * is managed in userspace ... OBEX, PTP, and MTP have been mentioned.

+ *
+ * Host Wire Adapter is the 'WUSB 1.0 standard' name for Wireless-USB
+ * Host Controller that is connected to your system via USB (a USB
+ * dongle that implements a USB host...). There is also a Device Wired
+ * Adaptor, DWA (Wireless USB hub) that uses the same mechanism for
+ * transferring data (it is after all a USB host connected via
+ * Wireless USB), we have a common layer called Wire Adapter Host
+ * Controller that does all the hard work. The WUSBHC (Wireless USB
+ * Host Controller) is the part common to WUSB Host Controllers, the
+ * HWA and the PCI-based one, that is implemented following the WHCI
+ * spec. All these layers are implemented in ../wusbcore.
+ *
+ * The main functions are hwahc_op_urb_{en,de}queue(), that pass the
+ * job of converting a URB to a Wire Adapter
+ *
+ * Entry points:
+ *
+ * hwahc_driver_*() Driver initialization, registration and
+ * teardown.
+ *
+ * hwahc_probe() New device came up, create an instance for
+ * it [from device enumeration].
+ *
+ * hwahc_disconnect() Remove device instance [from device
+ * enumeration].
+ *
+ * [__]hwahc_op_*() Host-Wire-Adaptor specific functions for

+ *
+ *
+ * WUSB devices have to be paired (authenticated in WUSB lingo) so
+ * that they can connect to the system.
+ *
+ * One way of pairing is using CBA-Cable Based Authentication, devices
+ * that can connect via wired or wireless USB. First time you plug
+ * them with a cable, pairing is done between host and device and
+ * subsequent times, you can connect wirelessly without having to
+ * pair. That's the idea.
+ *
+ * This driver does nothing Earth shattering. It just provides an
+ * interface to chat with the wire-connected device so we can get a
+ * CDID (device ID) that might have been previously associated to a
+ * CHID (host ID) and to set up a new <CHID,CDID,CK> triplet
+ * (connection context), with the CK being the secret, or connection
+ * key. This is the pairing data.
+ *
+ * When a device with the CBA capability connects, the probe routine
+ * just creates a bunch of sysfs files that a user space enumeration
+ * manager uses to allow it to connect wirelessly to the system or not.
+ *
+ * The process goes like this:
+ *
+ * 1. device plugs, cbaf is loaded, notifications happen
+ *
+ * 2. the connection manager sees a device with CBAF capability (the
+ * wusb_{host_info,cdid,cc} files are in /sys/device/blah/OURDEVICE).
+ *
+ * 3. CM (connection manager) writes the CHID (host ID) and a host
+ * name into the wusb_host_info file. This gets sent to the device.
+ *
+ * 4. CM cats the wusb_cdid file; this asks the device if it has any
+ * CDID associated to the CHDI we just wrote before. If it does, it
+ * is printed, along with the device 'friendly name' and the band
+ * groups the device supports.
+ *
+ * 5. CM looks up its database
+ *
+ * 5.1 If it has a matching CHID,CDID entry, the device has been
+ * authorized before (paired). Now we can optionally ask the user
+ * if he wants to allow the device to connect. Then we generate a
+ * new CDID and CK, send it to the device and update the database
+ * (writing to the wusb_cc file so they are uploaded to the device).
+ *
+ * 5.2 If the CDID is zero (or we didn't find a matching CDID in our
+ * database), we assume the device is not known. We ask the user
+ * if s/he wants to allow the device to be connected wirelessly
+ * to the system. If nope, nothing else is done (FIXME: maybe
+ * send a zero CDID to clean up our CHID?). If yes, we generate
+ * random CDID and CKs (and write them to the wusb_cc file so
+ * they are uploaded to the device).
+ *
+ * 6. device is unplugged
+ *
+ * When the device tries to connect wirelessly, it will present it's
+ * CDID to the WUSB host controller with ID CHID, which will query the
+ * database. If found, the host will (with a 4way handshake) challenge
+ * the device to demonstrate it has the CK secret key (from our
+ * database) without actually exchanging it. Once satisfied, crypto
+ * keys are derived from the CK, the device is connected and all
+ * communication is crypted.
+ *
+ *
+ * NOTES ABOUT THE IMPLEMENTATION
+ *
+ * The descriptors sent back and forth use this horrible format from
+ * hell on which each field is actually a field ID, field length and
+ * then the field itself. How stupid can that get, taking into account
+ * the structures are defined by the spec?? oh well.
+ *
+ *
+ * FIXME: we don't provide a way to tell the device the pairing failed
+ * (ie: send a CC_DATA_FAIL). Should add some day.

+ * CC-MAC function WUSB1.0[6.5]
+ *
+ * Take a data string and produce the encrypted CBC Counter-mode MIC
+ *
+ * Note the names for most function arguments are made to (more or
+ * less) match those used in the pseudo-function definition given in
+ * WUSB1.0[6.5].
+ *
+ * @tfm_cbc: CBC(AES) blkcipher handle (initialized)
+ *
+ * @tfm_aes: AES cipher handle (initialized)
+ *
+ * @mic: buffer for placing the computed MIC (Message Integrity
+ * Code). This is exactly 8 bytes, and we expect the buffer to
+ * be at least eight bytes in length.
+ *
+ * @key: 128 bit symmetric key
+ *
+ * @n: CCM nonce
+ *
+ * @a: ASCII string, 14 bytes long (I guess zero padded if needed;
+ * we use exactly 14 bytes).
+ *
+ * @b: data stream to be processed; cannot be a global or const local
+ * (will confuse the scatterlists)
+ *
+ * @blen: size of b...
+ *
+ * Still not very clear how this is done, but looks like this: we
+ * create block B0 (as WUSB1.0[6.5] says), then we AES-crypt it with
+ * @key. We bytewise xor B0 with B1 (1) and AES-crypt that. Then we
+ * take the payload and divide it in blocks (16 bytes), xor them with
+ * the previous crypto result (16 bytes) and crypt it, repeat the next
+ * block with the output of the previous one, rinse wash (I guess this
+ * is what AES CBC mode means...but I truly have no idea). So we use
+ * the CBC(AES) blkcipher, that does precisely that. The IV (Initial
+ * Vector) is 16 bytes and is set to zero, so
+ *
+ * See rfc3610. Linux crypto has a CBC implementation, but the
+ * documentation is scarce, to say the least, and the example code is
+ * so intricated that is difficult to understand how things work. Most
+ * of this is guess work -- bite me.
+ *
+ * (1) Created as 6.5 says, again, using as l(a) 'Blen + 14', and
+ * using the 14 bytes of @a to fill up
+ * b1.{mac_header,e0,security_reserved,padding}.
+ *
+ * NOTE: The definiton of l(a) in WUSB1.0[6.5] vs the definition of
+ * l(m) is orthogonal, they bear no relationship, so it is not
+ * in conflict with the parameter's relation that
+ * WUSB1.0[6.4.2]) defines.
+ *
+ * NOTE: WUSB1.0[A.1]: Host Nonce is missing a nibble? (1e); fixed in
+ * first errata released on 2005/07.
+ *
+ * NOTE: we need to clean IV to zero at each invocation to make sure
+ * we start with a fresh empty Initial Vector, so that the CBC
+ * works ok.
+ *
+ * NOTE: blen is not aligned to a block size, we'll pad zeros, that's
+ * what sg[4] is for. Maybe there is a smarter way to do this.

+ *
+ *
+ * WUSB1.0[7.1, 7.5.1, ]
+ *
+ * WUSB device connection is kind of messy. Some background:
+ *
+ * When a device wants to connect it scans the UWB radio channels
+ * looking for a WUSB Channel; a WUSB channel is defined by MMCs
+ * (Micro Managed Commands or something like that) [see
+ * Design-overview for more on this] .
+ *
+ * So, device scans the radio, finds MMCs and thus a host and checks
+ * when the next DNTS is. It sends a Device Notification Connect
+ * (DN_Connect); the host picks it up (through nep.c and notif.c, ends
+ * up in wusb_devconnect_ack(), which creates a wusb_dev structure in
+ * wusbhc->port[port_number].wusb_dev), assigns an unauth address
+ * to the device (this means from 0x80 to 0xfe) and sends, in the MMC
+ * a Connect Ack Information Element (ConnAck IE).
+ *
+ * So now the device now has a WUSB address. From now on, we use
+ * that to talk to it in the RPipes.
+ *
+ * ASSUMPTIONS:
+ *
+ * - We use the the as device address the port number where it is
+ * connected (port 0 doesn't exist). For unauth, it is 128 + that.
+ *
+ * ROADMAP:
+ *
+ * This file contains the logic for doing that--entry points:
+ *
+ * wusb_devconnect_ack() Ack a device until _acked() called.
+ * Called by notif.c:wusb_handle_dn_connect()
+ * when a DN_Connect is received.
+ *
+ * wusbhc_devconnect_auth() Called by rh.c:wusbhc_rh_port_reset() when
+ * doing the device connect sequence.
+ *
+ * wusb_devconnect_acked() Ack done, release resources.
+ *
+ * wusb_handle_dn_alive() Called by notif.c:wusb_handle_dn()
+ * for processing a DN_Alive pong from a device.
+ *
+ * wusb_handle_dn_disconnect()Called by notif.c:wusb_handle_dn() to
+ * process a disconenct request from a
+ * device.
+ *
+ * wusb_dev_reset() Called by rh.c:wusbhc_rh_port_reset() when
+ * resetting a device.
+ *
+ * __wusb_dev_disable() Called by rh.c:wusbhc_rh_clear_port_feat() when
+ * disabling a port.
+ *
+ * wusb_devconnect_create() Called when creating the host by
+ * lc.c:wusbhc_create().
+ *
+ * wusb_devconnect_destroy() Cleanup called removing the host. Called
+ * by lc.c:wusbhc_destroy().
+ *
+ * Each Wireless USB host maintains a list of DN_Connect requests
+ * (actually we maintain a list of pending Connect Acks, the
+ * wusbhc->ca_list).
+ *
+ * LIFE CYCLE OF port->wusb_dev
+ *
+ * Before the @wusbhc structure put()s the reference it owns for
+ * port->wusb_dev [and clean the wusb_dev pointer], it needs to
+ * lock @wusbhc->mutex.

+ * We fake a root hub that has fake ports (as many as simultaneous
+ * devices the Wireless USB Host Controller can deal with). For each
+ * port we keep an state in @wusbhc->port[index] identical to the one
+ * specified in the USB2.0[ch11] spec and some extra device
+ * information that complements the one in 'struct usb_device' (as
+ * this lacs a hcpriv pointer).
+ *
+ * Note this is common to WHCI and HWA host controllers.
+ *
+ * Through here we enable most of the state changes that the USB stack
+ * will use to connect or disconnect devices. We need to do some
+ * forced adaptation of Wireless USB device states vs. wired:
+ *
+ * USB: WUSB:
+ *
+ * Port Powered-off port slot n/a
+ * Powered-on port slot available
+ * Disconnected port slot available
+ * Connected port slot assigned device
+ * device sent DN_Connect
+ * device was authenticated
+ * Enabled device is authenticated, transitioned
+ * from unauth -> auth -> default address
+ * -> enabled
+ * Reset disconnect
+ * Disable disconnect
+ *
+ * This maps the standard USB port states with the WUSB device states
+ * so we can fake ports without having to modify the USB stack.
+ *

+ *
+ *
+ * This driver implements a USB Host Controller (struct usb_hcd) for a
+ * Wireless USB Host Controller based on the Wireless USB 1.0
+ * Host-Wire-Adapter specification (in layman terms, a USB-dongle that
+ * implements a Wireless USB host).
+ *
+ * Check out the Design-overview.txt file in the source documentation
+ * for other details on the implementation.
+ *
+ * Main blocks:
+ *
+ * driver glue with the driver API, workqueue daemon
+ *
+ * lc RC instance life cycle management (create, destroy...)
+ *
+ * hcd glue with the USB API Host Controller Interface API.
+ *
+ * nep Notification EndPoint managent: collect notifications
+ * and queue them with the workqueue daemon.
+ *
+ * Handle notifications as coming from the NEP. Sends them
+ * off others to their respective modules (eg: connect,
+ * disconnect and reset go to devconnect).
+ *
+ * rpipe Remote Pipe management; rpipe is what we use to write
+ * to an endpoint on a WUSB device that is connected to a
+ * HWA RC.
+ *
+ * xfer Transfer managment -- this is all the code that gets a
+ * buffer and pushes it to a device (or viceversa). *
+ *
+ * Some day a lot of this code will be shared between this driver and
+ * the drivers for DWA (xfer, rpipe).
+ *
+ * All starts at driver.c:hwahc_probe(), when one of this guys is
+ * connected. hwahc_disconnect() stops it.
+ *
+ * During operation, the main driver is devices connecting or
+ * disconnecting. They cause the HWA RC to send notifications into
+ * nep.c:hwahc_nep_cb() that will dispatch them to
+ * notif.c:wa_notif_dispatch(). From there they will fan to cause
+ * device connects, disconnects, etc.
+ *
+ * Note much of the activity is difficult to follow. For example a
+ * device connect goes to devconnect, which will cause the "fake" root
+ * hub port to show a connect and stop there. Then khubd will notice
+ * and call into the rh.c:hwahc_rc_port_reset() code to authenticate
+ * the device (and this might require user intervention) and enable
+ * the port.
+ *
+ * We also have a timer workqueue going from devconnect.c that
+ * schedules in hwahc_devconnect_create().
+ *
+ * The rest of the traffic is in the usual entry points of a USB HCD,
+ * which are hooked up in driver.c:hwahc_rc_driver, and defined in
+ * hcd.c.

+ * This part takes care of getting the notification from the hw
+ * only and dispatching through wusbwad into
+ * wa_notif_dispatch. Handling is done there.
+ *
+ * WA notifications are limited in size; most of them are three or
+ * four bytes long, and the longest is the HWA Device Notification,
+ * which would not exceed 38 bytes (DNs are limited in payload to 32
+ * bytes plus 3 bytes header (WUSB1.0[7.6p2]), plus 3 bytes HWA
+ * header (WUSB1.0[8.5.4.2]).
+ *
+ * It is not clear if more than one Device Notification can be packed
+ * in a HWA Notification, I assume no because of the wording in
+ * WUSB1.0[8.5.4.2]. In any case, the bigger any notification could
+ * get is 256 bytes (as the bLength field is a byte).
+ *
+ * So what we do is we have this buffer and read into it; when a
+ * notification arrives we schedule work to a specific, single thread
+ * workqueue (so notifications are serialized) and copy the
+ * notification data. After scheduling the work, we rearm the read from
+ * the notification endpoint.

+ * endpoint; when data is ready, this

+ * Targetted at different downstream endpoints
+ *
+ * Descriptor: use to config the remote pipe.
+ *
+ * The number of blocks could be dynamic (wBlocks in descriptor is
+ * 0)--need to schedule them then.
+ *
+ * Each bit in wa->rpipe_bm represents if an rpipe is being used or
+ * not. Rpipes are represented with a 'struct wa_rpipe' that is
+ * attached to the hcpriv member of a 'struct usb_host_endpoint'.
+ *
+ * When you need to xfer data to an endpoint, you get an rpipe for it
+ * with wa_ep_rpipe_get(), which gives you a reference to the rpipe
+ * and keeps a single one (the first one) with the endpoint. When you
+ * are done transferring, you drop that reference. At the end the
+ * rpipe is always allocated and bound to the endpoint. There it might
+ * be recycled when not used.
+ *
+ * Addresses:
+ *
+ * We use a 1:1 mapping mechanism between port address (0 based
+ * index, actually) and the address. The USB stack knows about this.
+ *
+ * USB Stack port number 4 (1 based)
+ * WUSB code port index 3 (0 based)
+ * USB Addresss 5 (2 based -- 0 is for default, 1 for root hub)
+ *
+ * Now, because we don't use the concept as default address exactly
+ * like the (wired) USB code does, we need to kind of skip it. So we
+ * never take addresses from the urb->pipe, but from the
+ * urb->dev->devnum, to make sure that we always have the right
+ * destination address.

+ * How transfers work: get a buffer, break it up in segments (segment
+ * size is a multiple of the maxpacket size). For each segment issue a
+ * segment request (struct wa_xfer_*), then send the data buffer if
+ * out or nothing if in (all over the DTO endpoint).
+ *
+ * For each submitted segment request, a notification will come over
+ * the NEP endpoint and a transfer result (struct xfer_result) will
+ * arrive in the DTI URB. Read it, get the xfer ID, see if there is
+ * data coming (inbound transfer), schedule a read and handle it.
+ *
+ * Sounds simple, it is a pain to implement.

+ * THIS CODE IS DISGUSTING
+ *
+ * Warned you are; it's my second try and still not happy with it.
+ *
+ * NOTES:
+ *
+ * - No iso
+ *
+ * - Supports DMA xfers, control, bulk and maybe interrupt
+ *
+ * - Does not recycle unused rpipes
+ *
+ * An rpipe is assigned to an endpoint the first time it is used,
+ * and then it's there, assigned, until the endpoint is disabled
+ * (destroyed [{h,d}wahc_op_ep_disable()]. The assignment of the
+ * rpipe to the endpoint is done under the wa->rpipe_sem semaphore
+ * (should be a mutex).
+ *
+ * Two methods it could be done:
+ *
+ * (a) set up a timer everytime an rpipe's use count drops to 1
+ * (which means unused) or when a transfer ends. Reset the
+ * timer when a xfer is queued. If the timer expires, release
+ * the rpipe [see rpipe_ep_disable()].
+ *
+ * (b) when looking for free rpipes to attach [rpipe_get_by_ep()],
+ * when none are found go over the list, check their endpoint
+ * and their activity record (if no last-xfer-done-ts in the
+ * last x seconds) take it
+ *
+ * However, due to the fact that we have a set of limited
+ * resources (max-segments-at-the-same-time per xfer,
+ * xfers-per-ripe, blocks-per-rpipe, rpipes-per-host), at the end
+ * we are going to have to rebuild all this based on an scheduler,
+ * to where we have a list of transactions to do and based on the
+ * availability of the different requried components (blocks,
+ * rpipes, segment slots, etc), we go scheduling them. Painful.

+ *
+ * - whci: WHCI, a PCI card with a wireless host controller
+ * (Wireless Host Controller Interface 1.0 specification).
+ *
+ * Check out the Design-overview.txt file in the source documentation
+ * for other details on the implementation.
+ *
+ * Main blocks:
+ *
+ * rh Root Hub emulation (part of the HCD glue)
+ *
+ * devconnect Handle all the issues related to device connection,
+ * authentication, disconnection, timeout, reseting,
+ * keepalives, etc.
+ *
+ * mmc MMC IE broadcasting handling
+ *
+ * A host controller driver just initializes its stuff and as part of
+ * that, creates a 'struct wusbhc' instance that handles all the
+ * common WUSB mechanisms. Links in the function ops that are specific
+ * to it and then registers the host controller. Ready to run.

+ * All fields that are common to all Wireless USB controller types
+ * (HWA and WHCI) are grouped here. Host Controller
+ * functions/operations that only deal with general Wireless USB HC
+ * issues use this data type to refer to the host.
+ *
+ * @usb_hcd Instantiation of a USB host controller
+ * (initialized by upper layer [HWA=HC or WHCI].
+ *
+ * @dev Device that implements this; initialized by the
+ * upper layer (HWA-HC, WHCI...); this device should
+ * have a refcount.
+ *
+ * @trust_timeout After this time without hearing for device
+ * activity, we consider the device gone and we have to
+ * re-authenticate.
+ *
+ * Can be accessed w/o locking--however, read to a
+ * local variable then use.
+ *
+ * @chid WUSB Cluster Host ID: this is supposed to be a
+ * unique value that doesn't change across reboots (so
+ * that your devices do not require re-association).
+ *
+ * Read/Write protected by @mutex
+ *
+ * @dev_info This array has ports_max elements. It is used to
+ * give the HC information about the WUSB devices (see
+ * 'struct wusb_dev_info').
+ *
+ * For HWA we need to allocate it in heap; for WHCI it
+ * needs to be permanently mapped, so we keep it for
+ * both and make it easy. Call wusbhc->dev_info_set()
+ * to update an entry.
+ *
+ * @ports_max Number of simultaneous device connections (fake
+ * ports) this HC will take. Read-only.
+ *
+ * @port Array of port status for each fake root port. Guaranteed to
+ * always be the same lenght during device existence
+ * [this allows for some unlocked but referenced reading].
+ *
+ * @mmcies_max Max number of Information Elements this HC can send
+ * in its MMC. Read-only.
+ *
+ * @mmcie_add HC specific operation (WHCI or HWA) for adding an
+ * MMCIE.
+ *
+ * @mmcie_rm HC specific operation (WHCI or HWA) for removing an
+ * MMCIE.
+ *
+ * @enc_types Array which describes the encryptions methods
+ * supported by the host as described in WUSB1.0 --
+ * one entry per supported method. As of WUSB1.0 there
+ * is only four methods, we make space for eight just in
+ * case they decide to add some more (and pray they do
+ * it in sequential order). if 'enc_types[enc_method]
+ * != 0', then it is supported by the host. enc_method
+ * is USB_ENC_TYPE*.
+ *
+ * @set_ptk: Set the PTK and enable encryption for a device. Or, if
+ * the supplied key is NULL, disable encryption for that
+ * device.
+ *
+ * @set_gtk: Set the GTK to be used for all future broadcast packets
+ * (i.e., MMCs). With some hardware, setting the GTK may start
+ * MMC transmission.
+ *
+ * NOTE:
+ *
+ * - If wusb_dev->usb_dev is not NULL, then usb_dev is valid
+ * (wusb_dev has a refcount on it). Likewise, if usb_dev->wusb_dev
+ * is not NULL, usb_dev->wusb_dev is valid (usb_dev keeps a
+ * refcount on it).
+ *
+ * Most of the times when you need to use it, it will be non-NULL,
+ * so there is no real need to check for it (wusb_dev will
+ * dissapear before usb_dev).
+ *
+ * - The following fields need to be filled out before calling
+ * wusbhc_create(): ports_max, mmcies_max, mmcie_{add,rm}.
+ *
+ * - there is no wusbhc_init() method, we do everything in
+ * wusbhc_create().
+ *
+ * - Creation is done in two phases, wusbhc_create() and
+ * wusbhc_create_b(); b are the parts that need to be called after
+ * calling usb_hcd_add(&wusbhc->usb_hcd).

+ help
+ UWB is a high-bandwidth, low-power, point-to-point radio
+ technology using a wide spectrum (3.1-10.6GHz). It is
+ optimized for in-room use (480Mbps at 2 meters, 110Mbps at
+ 10m). It serves as the transport layer for other protocols,
+ such as Wireless USB (WUSB), IP (WLP) and upcoming
+ Bluetooth and 1394
+
+ The topology is peer to peer; however, higher level
+ protocols (such as WUSB) might impose a master/slave
+ relationship.
+
+ Say Y here if your computer has UWB radio controllers (USB or PCI)
+ based. You will need to enable the radio controllers
+ below. It is ok to select all of them, no harm done.
+
+ For more help check the UWB and WUSB related files in
+ <file:Documentation/usb/>.
+
+ To compile the UWB stack as a module, choose M here.

+ * that the device expects. Only a few messages are affected:
+ * Affected events:
+ * UWB_RC_EVT_BEACON
+ * UWB_RC_EVT_BP_SLOT_CHANGE
+ * UWB_RC_EVT_DRP_AVAIL

+ * This driver is the firmware uploader for the Intel Wireless UWB
+ * Link 1480 device (both in the USB and PCI incarnations).
+ *
+ * The process is quite simple: we stop the device, write the firmware
+ * to its memory and then restart it. Wait for the device to let us
+ * know it is done booting firmware. Ready.
+ *
+ * We might have to upload before or after a phy firmware (which might
+ * be done in two methods, using a normal firmware image or through
+ * the MPI port).
+ *
+ * Because USB and PCI use common methods, we just make ops out of the
+ * common operations (read, write, wait_init_done and cmd) and
+ * implement them in usb.c and pci.c.
+ *
+ * The flow is (some parts omitted):
+ *
+ * i1480_{usb,pci}_probe() On enumerate/discovery
+ * i1480_fw_upload()
+ * i1480_pre_fw_upload()

+ * i1480_mpi_write()
+ * i1480->cmd() [i1480_{usb,pci}_cmd()]
+ * i1480_check_info()
+ *
+ * Once the probe function enumerates the device and uploads the
+ * firmware, we just exit with -ENODEV, as we don't really want to
+ * attach to the device.

+ * i1480u's RX handling is simple. i1480u will send the received
+ * network packets broken up in fragments; 1 to N fragments make a
+ * packet, we assemble them together and deliver the packet with netif_rx().
+ *
+ * Beacuse each USB transfer is a *single* fragment (except when the
+ * transfer contains a first fragment), each URB called thus
+ * back contains one or two fragments. So we queue N URBs, each with its own
+ * fragment buffer. When a URB is done, we process it (adding to the
+ * current skb from the fragment buffer until complete). Once
+ * processed, we requeue the URB. There is always a bunch of URBs
+ * ready to take data, so the intergap should be minimal.
+ *
+ * An URB's transfer buffer is the data field of a socket buffer. This
+ * reduces copying as data can be passed directly to network layer. If a
+ * complete packet or 1st fragment is received the URB's transfer buffer is
+ * taken away from it and used to send data to the network layer. In this
+ * case a new transfer buffer is allocated to the URB before being requeued.
+ * If a "NEXT" or "LAST" fragment is received, the fragment contents is
+ * appended to the RX packet under construction and the transfer buffer
+ * is reused. To be able to use this buffer to assemble complete packets
+ * we set each buffer's size to that of the MAX ethernet packet that can
+ * be received. There is thus room for improvement in memory usage.
+ *
+ * When the max tx fragment size increases, we should be able to read
+ * data into the skbs directly with very simple code.

+ * Looks like a transfer can contain more than one fragment (07/18/06)

+ *
+ * - We always read the full USB-transfer, no partials.
+ *
+ * - Each transfer is read directly into a skb. This skb will be used to
+ * send data to the upper layers if it is the first fragment or a complete
+ * packet. In the other cases the data will be copied from the skb to
+ * another skb that is being prepared for the upper layers from a prev
+ * first fragment.
+ *
+ * It is simply too much of a pain. Gosh, there should be a unified
+ * SG infrastructure for *everything* [so that I could declare a SG
+ * buffer, pass it to USB for receiving, append some space to it if
+ * I wish, receive more until I have the whole chunk, adapt
+ * pointers on each fragment to remove hardware headers and then

+ *
+ *
+ * The RC interface of the Host Wire Adapter (USB dongle) or WHCI PCI
+ * card delivers a stream of notifications and events to the
+ * notification end event endpoint or area. This code takes care of
+ * getting a buffer with that data, breaking it up in separate
+ * notifications and events and then deliver those.
+ *
+ * Events are answers to commands and they carry a context ID that
+ * associates them to the command. Notifications are that,
+ * notifications, they come out of the blue and have a context ID of
+ * zero. Think of the context ID kind of like a handler. The
+ * uwb_rc_neh_* code deals with managing context IDs.
+ *
+ * This is why you require a handle to operate on a UWB host. When you
+ * open a handle a context ID is assigned to you.
+ *
+ * So, as it is done is:
+ *
+ * 1. Add an event handler [uwb_rc_neh_add()] (assigns a ctx id)
+ * 2. Issue command [rc->cmd(rc, ...)]
+ * 3. Arm the timeout timer [uwb_rc_neh_arm()]
+ * 4, Release the reference to the neh [uwb_rc_neh_put()]
+ * 5. Wait for the callback
+ * 6. Command result (RCEB) is passed to the callback
+ *
+ * If (2) fails, you should remove the handle [uwb_rc_neh_rm()]
+ * instead of arming the timer.
+ *
+ * Handles are for using in *serialized* code, single thread.
+ *
+ * When the notification/event comes, the IRQ handler/endpoint
+ * callback passes the data read to uwb_rc_neh_grok() which will break
+ * it up in a discrete series of events, look up who is listening for
+ * them and execute the pertinent callbacks.
+ *
+ * If the reader detects an error while reading the data stream, call
+ * uwb_rc_neh_error().
+ *
+ * CONSTRAINTS/ASSUMPTIONS:
+ *
+ * - Most notifications/events are small (less thank .5k), copying
+ * around is ok.
+ *
+ * - Notifications/events are ALWAYS smaller than PAGE_SIZE
+ *
+ * - Notifications/events always come in a single piece (ie: a buffer
+ * will always contain entire notifications/events).
+ *
+ * - we cannot know in advance how long each event is (because they
+ * lack a length field in their header--smart move by the standards
+ * body, btw). So we need a facility to get the event size given the
+ * header. This is what the EST code does (notif/Event Size
+ * Tables), check nest.c--as well, you can associate the size to
+ * the handle [w/ neh->extra_size()].
+ *
+ * - Most notifications/events are fixed size; only a few are variable
+ * size (NEST takes care of that).
+ *
+ * - Listeners of events expect them, so they usually provide a
+ * buffer, as they know the size. Listeners to notifications don't,
+ * so we allocate their buffers dynamically.

+ *
+ * This daemon takes care of maintaing information that describes the
+ * UWB neighborhood that the radios in this machine can see. It also
+ * keeps a tab of which devices are visible, makes sure each HC sits
+ * on a different channel to avoid interfering, etc.
+ *
+ * Different drivers (radio controller, device, any API in general)
+ * communicate with this daemon through an event queue. Daemon wakes
+ * up, takes a list of events and handles them one by one; handling
+ * function is extracted from a table based on the event's type and
+ * subtype. Events are freed only if the handling function says so.
+ *
+ * . Lock protecting the event list has to be an spinlock and locked
+ * with IRQSAVE because it might be called from an interrupt
+ * context (ie: when events arrive and the notification drops
+ * down from the ISR).
+ *
+ * . UWB radio controller drivers queue events to the daemon using
+ * uwbd_event_queue(). They just get the event, chew it to make it
+ * look like UWBD likes it and pass it in a buffer allocated with
+ * uwb_event_alloc().
+ *
+ * EVENTS
+ *
+ * Events have a type, a subtype, a lenght, some other stuff and the
+ * data blob, which depends on the event. The header is 'struct
+ * uwb_event'; for payloads, see 'struct uwbd_evt_*'.
+ *
+ * EVENT HANDLER TABLES
+ *
+ * To find a handling function for an event, the type is used to index
+ * a subtype-table in the type-table. The subtype-table is indexed
+ * with the subtype to get the function that handles the event. Start
+ * with the main type-table 'uwbd_evt_type_handler'.
+ *
+ * DEVICES
+ *
+ * Devices are created when a bunch of beacons have been received and
+ * it is stablished that the device has stable radio presence. CREATED
+ * only, not configured. Devices are ONLY configured when an
+ * Application-Specific IE Probe is receieved, in which the device
+ * declares which Protocol ID it groks. Then the device is CONFIGURED
+ * (and the driver->probe() stuff of the device model is invoked).
+ *
+ * Devices are considered disconnected when a certain number of
+ * beacons are not received in an amount of time.
+ *
+ * Handler functions are called normally uwbd_evt_handle_*().

+ * We need to be able to map ethernet addresses to device addresses
+ * and back because there is not explicit relationship between the eth
+ * addresses used in the ETH frames and the device addresses (no, it
+ * would not have been simpler to force as ETH address the MBOA MAC
+ * address...no, not at all :).
+ *
+ * A device has one MBOA MAC address and one device address. It is possible
+ * for a device to have more than one virtual MAC address (although a
+ * virtual address can be the same as the MBOA MAC address). The device
+ * address is guaranteed to be unique among the devices in the extended
+ * beacon group (see ECMA 17.1.1). We thus use the device address as index
+ * to this cache. We do allow searching based on virtual address as this
+ * is how Ethernet frames will be addressed.
+ *
+ * We need to support virtual EUI-48. Although, right now the virtual
+ * EUI-48 will always be the same as the MAC SAP address. The EDA cache
+ * entry thus contains a MAC SAP address as well as the virtual address
+ * (used to map the network stack address to a neighbor). When we move
+ * to support more than one virtual MAC on a host then this organization
+ * will have to change. Perhaps a neighbor has a list of WSSs, each with a
+ * tag and virtual EUI-48.
+ *
+ * On data transmission
+ * it is used to determine if the neighbor is connected and what WSS it
+ * belongs to. With this we know what tag to add to the WLP frame. Storing
+ * the WSS in the EDA cache may be overkill because we only support one
+ * WSS. Hopefully we will support more than one WSS at some point.
+ * On data reception it is used to determine the WSS based on
+ * the tag and address of the transmitting neighbor.

+ *
+ * The network stack (WLP client) is attempting to transmit a frame. We can
+ * only transmit data if a local WSS is at least active (connection will be
+ * done here if this is a broadcast frame and neighbor also has the WSS
+ * active).
+ *
+ * The frame can be either broadcast or unicast. Broadcast in a WSS is
+ * supported via multicast, but we don't support multicast yet (until
+ * devices start to support MAB IEs). If a broadcast frame needs to be
+ * transmitted it is treated as a unicast frame to each neighbor. In this
+ * case the WLP takes over transmission of the skb and returns 1
+ * to the caller to indicate so. Also, in this case, if a neighbor has the
+ * same WSS activated but is not connected then the WSS connection will be
+ * done at this time. The neighbor's virtual address will be learned at
+ * this time.
+ *
+ * The destination address in a unicast frame is the virtual address of the
+ * neighbor. This address only becomes known when a WSS connection is
+ * established. We thus rely on a broadcast frame to trigger the setup of
+ * WSS connections to all neighbors before we are able to send unicast
+ * frames to them. This seems reasonable as IP would usually use ARP first
+ * before any unicast frames are sent.
+ *
+ * If we are already connected to the neighbor (neighbor's virtual address
+ * is known) we just prepare the WLP header and the caller will continue to
+ * send the frame.
+ *
+ * A failure in this function usually indicates something that cannot be
+ * fixed automatically. So, if this function fails (@return < 0) the calling
+ * function should not retry to send the frame as it will very likely keep
+ * failing.

DFS support added (Microsoft Distributed File System client support needed
for referrals which enable a hierarchical name space among servers).
+Disable temporary caching of mode bits to servers which do not support
+storing of mode (e.g. Windows servers, when client mounts without cifsacl
+mount option) and add new "dynperm" mount option to enable temporary caching
+of mode (enable old behavior). Fix hang on mount caused when server crashes

* to the rest of the driver stack (such as a driver that's ON gating off
* clocks which are not in active use).
*
+ * The externally visible transitions are handled with the help of the following
+ * callbacks included in this structure:
+ *
+ * @prepare: Prepare the device for the upcoming transition, but do NOT change
+ * its hardware state. Prevent new children of the device from being
+ * registered after @prepare() returns (the driver's subsystem and
+ * generally the rest of the kernel is supposed to prevent new calls to the
+ * probe method from being made too once @prepare() has succeeded). If
+ * @prepare() detects a situation it cannot handle (e.g. registration of a
+ * child already in progress), it may return -EAGAIN, so that the PM core
+ * can execute it once again (e.g. after the new child has been registered)
+ * to recover from the race condition. This method is executed for all
+ * kinds of suspend transitions and is followed by one of the suspend
+ * callbacks: @suspend(), @freeze(), or @poweroff().
+ * The PM core executes @prepare() for all devices before starting to
+ * execute suspend callbacks for any of them, so drivers may assume all of
+ * the other devices to be present and functional while @prepare() is being
+ * executed. In particular, it is safe to make GFP_KERNEL memory
+ * allocations from within @prepare(). However, drivers may NOT assume
+ * anything about the availability of the user space at that time and it
+ * is not correct to request firmware from within @prepare() (it's too
+ * late to do that). [To work around this limitation, drivers may
+ * register suspend and hibernation notifiers that are executed before the
+ * freezing of tasks.]
+ *
+ * @complete: Undo the changes made by @prepare(). This method is executed for
+ * all kinds of resume transitions, following one of the resume callbacks:
+ * @resume(), @thaw(), @restore(). Also called if the state transition
+ * fails before the driver's suspend callback (@suspend(), @freeze(),
+ * @poweroff()) can be executed (e.g. if the suspend callback fails for one
+ * of the other devices that the PM core has unsuccessfully attempted to
+ * suspend earlier).
+ * The PM core executes @complete() after it has executed the appropriate
+ * resume callback for all devices.
+ *
+ * @suspend: Executed before putting the system into a sleep state in which the
+ * contents of main memory are preserved. Quiesce the device, put it into
+ * a low power state appropriate for the upcoming system state (such as
+ * PCI_D3hot), and enable wakeup events as appropriate.
+ *
+ * @resume: Executed after waking the system up from a sleep state in which the
+ * contents of main memory were preserved. Put the device into the
+ * appropriate state, according to the information saved in memory by the
+ * preceding @suspend(). The driver starts working again, responding to
+ * hardware events and software requests. The hardware may have gone
+ * through a power-off reset, or it may have maintained state from the
+ * previous suspend() which the driver may rely on while resuming. On most
+ * platforms, there are no restrictions on availability of resources like
+ * clocks during @resume().
+ *

+ * struct usb_function - describes one function of a configuration
+ * @name: For diagnostics, identifies the function.
+ * @strings: tables of strings, keyed by identifiers assigned during bind()
+ * and by language IDs provided in control requests
+ * @descriptors: Table of full (or low) speed descriptors, using interface and
+ * string identifiers assigned during @bind(). If this pointer is null,
+ * the function will not be available at full speed (or at low speed).
+ * @hs_descriptors: Table of high speed descriptors, using interface and
+ * string identifiers assigned during @bind(). If this pointer is null,
+ * the function will not be available at high speed.
+ * @config: assigned when @usb_add_function() is called; this is the
+ * configuration with which this function is associated.
+ * @bind: Before the gadget can register, all of its functions bind() to the
+ * available resources including string and interface identifiers used
+ * in interface or class descriptors; endpoints; I/O buffers; and so on.
+ * @unbind: Reverses @bind; called as a side effect of unregistering the
+ * driver which added this function.
+ * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
+ * initialize usb_ep.driver data at this time (when it is used).
+ * Note that setting an interface to its current altsetting resets
+ * interface state, and that all interfaces have a disabled state.
+ * @get_alt: Returns the active altsetting. If this is not provided,
+ * then only altsetting zero is supported.
+ * @disable: (REQUIRED) Indicates the function should be disabled. Reasons
+ * include host resetting or reconfiguring the gadget, and disconnection.
+ * @setup: Used for interface-specific control requests.
+ * @suspend: Notifies functions when the host stops sending USB traffic.
+ * @resume: Notifies functions when the host restarts USB traffic.
+ *
+ * A single USB function uses one or more interfaces, and should in most
+ * cases support operation at both full and high speeds. Each function is
+ * associated by @usb_add_function() with a one configuration; that function
+ * causes @bind() to be called so resources can be allocated as part of
+ * setting up a gadget driver. Those resources include endpoints, which
+ * should be allocated using @usb_ep_autoconfig().
+ *
+ * To support dual speed operation, a function driver provides descriptors
+ * for both high and full speed operation. Except in rare cases that don't
+ * involve bulk endpoints, each speed needs different endpoint descriptors.
+ *
+ * Function drivers choose their own strategies for managing instance data.
+ * The simplest strategy just declares it "static', which means the function
+ * can only be activated once. If the function needs to be exposed in more
+ * than one configuration at a given speed, it needs to support multiple
+ * usb_function structures (one for each configuration).
+ *
+ * A more complex strategy might encapsulate a @usb_function structure inside
+ * a driver-specific instance structure to allows multiple activations. An
+ * example of multiple activations might be a CDC ACM function that supports
+ * two or more distinct instances within the same configuration, providing
+ * several independent logical data links to a USB host.

+ * device infrastructure or directed at a specific interface.
+ * @bConfigurationValue: Copied into configuration descriptor.
+ * @iConfiguration: Copied into configuration descriptor.
+ * @bmAttributes: Copied into configuration descriptor.

+ * Configurations are building blocks for gadget drivers structured around

+ * The lifecycle of a usb_configuration includes allocation, initialization
+ * of the fields described above, and calling @usb_add_config() to set up
+ * internal data and bind it to a specific device. The configuration's
+ * @bind() method is then used to initialize all the functions and then
+ * call @usb_add_function() for them.
+ *
+ * Those functions would normally be independant of each other, but that's
+ * not mandatory. CDC WMC devices are an example where functions often
+ * depend on other functions, with some functions subsidiary to others.
+ * Such interdependency may be managed in any way, so long as all of the

+ * UMC (UWB Multi-interface Controller) capabilities (e.g., radio
+ * controller, host controller) are presented as devices on the "umc"
+ * bus.
+ *
+ * The radio controller is not strictly a UMC capability but it's
+ * useful to present it as such.
+ *
+ * References:
+ *
+ * [WHCI] Wireless Host Controller Interface Specification for
+ * Certified Wireless Universal Serial Bus, revision 0.95.
+ *
+ * How this works is kind of convoluted but simple. The whci.ko driver
+ * loads when WHCI devices are detected. These WHCI devices expose
+ * many devices in the same PCI function (they couldn't have reused
+ * functions, no), so for each PCI function that exposes these many
+ * devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
+ * with umc_device_create() and adds it to the bus with
+ * umc_device_register().
+ *
+ * umc_device_register() calls device_register() which will push the
+ * bus management code to load your UMC driver's somehting_probe()
+ * that you have registered for that capability code.
+ *
+ * Now when the WHCI device is removed, whci_remove() will go over
+ * each umc_dev assigned to each of the PCI function's capabilities
+ * and through whci_del_cap() call umc_device_unregister() each
+ * created umc_dev. Of course, if you are bound to the device, your
+ * driver's something_remove() will be called.

+ * in that class). Therefore a typical application without affinity
+ * restrictions can find a suitable CPU with O(1) complexity (e.g. two bit
+ * searches). For tasks with affinity restrictions, the algorithm has a
+ * worst case complexity of O(min(102, nr_domcpus)), though the scenario that
