+dm-switch
+=========
+
+The device-mapper switch target creates a device that supports an
+arbitrary mapping of fixed-size regions of I/O across a fixed set of
+paths. The path used for any specific region can be switched
+dynamically by sending the target a message.
+
+It maps I/O to underlying block devices efficiently when there is a large
+number of fixed-sized address regions but there is no simple pattern
+that would allow for a compact representation of the mapping such as
+dm-stripe.
+
+Background
+----------
+
+Dell EqualLogic and some other iSCSI storage arrays use a distributed
+frameless architecture. In this architecture, the storage group
+consists of a number of distinct storage arrays ("members") each having
+independent controllers, disk storage and network adapters. When a LUN
+is created it is spread across multiple members. The details of the
+spreading are hidden from initiators connected to this storage system.
+The storage group exposes a single target discovery portal, no matter
+how many members are being used. When iSCSI sessions are created, each
+session is connected to an eth port on a single member. Data to a LUN
+can be sent on any iSCSI session, and if the blocks being accessed are
+stored on another member the I/O will be forwarded as required. This
+forwarding is invisible to the initiator. The storage layout is also
+dynamic, and the blocks stored on disk may be moved from member to
+member as needed to balance the load.
+
+This architecture simplifies the management and configuration of both
+the storage group and initiators. In a multipathing configuration, it
+is possible to set up multiple iSCSI sessions to use multiple network
+interfaces on both the host and target to take advantage of the
+increased network bandwidth. An initiator could use a simple round
+robin algorithm to send I/O across all paths and let the storage array
+members forward it as necessary, but there is a performance advantage to
+sending data directly to the correct member.
+
+A device-mapper table already lets you map different regions of a
+device onto different targets. However in this architecture the LUN is
+spread with an address region size on the order of 10s of MBs, which
+means the resulting table could have more than a million entries and
+consume far too much memory.
+
+Using this device-mapper switch target we can now build a two-layer
+device hierarchy:
+
+ Upper Tier – Determine which array member the I/O should be sent to.
+ Lower Tier – Load balance amongst paths to a particular member.
+
+The lower tier consists of a single dm multipath device for each member.
+Each of these multipath devices contains the set of paths directly to
+the array member in one priority group, and leverages existing path
+selectors to load balance amongst these paths. We also build a
+non-preferred priority group containing paths to other array members for
+failover reasons.
+
+The upper tier consists of a single dm-switch device. This device uses
+a bitmap to look up the location of the I/O and choose the appropriate
+lower tier device to route the I/O. By using a bitmap we are able to
+use 4 bits for each address range in a 16 member group (which is very
+large for us). This is a much denser representation than the dm table
+b-tree can achieve.

+Construction Parameters
+=======================
+
+ <num_paths> <region_size> <num_optional_args> [<optional_args>...]
+ [<dev_path> <offset>]+
+
+<num_paths>
+ The number of paths across which to distribute the I/O.
+
+<region_size>
+ The number of 512-byte sectors in a region. Each region can be redirected
+ to any of the available paths.
+
+<num_optional_args>
+ The number of optional arguments. Currently, no optional arguments
+ are supported and so this must be zero.
+
+<dev_path>
+ The block device that represents a specific path to the device.
+
+<offset>
+ The offset of the start of data on the specific <dev_path> (in units
+ of 512-byte sectors). This number is added to the sector number when
+ forwarding the request to the specific path. Typically it is zero.

+* ARM System MMU Architecture Implementation
+
+ARM SoCs may contain an implementation of the ARM System Memory
+Management Unit Architecture, which can be used to provide 1 or 2 stages
+of address translation to bus masters external to the CPU.
+
+The SMMU may also raise interrupts in response to various fault
+conditions.
+
+** System MMU required properties:
+
+- compatible : Should be one of:
+
+ "arm,smmu-v1"
+ "arm,smmu-v2"
+ "arm,mmu-400"
+ "arm,mmu-500"
+
+ depending on the particular implementation and/or the
+ version of the architecture implemented.
+
+- reg : Base address and size of the SMMU.
+
+- #global-interrupts : The number of global interrupts exposed by the
+ device.
+
+- interrupts : Interrupt list, with the first #global-irqs entries
+ corresponding to the global interrupts and any
+ following entries corresponding to context interrupts,
+ specified in order of their indexing by the SMMU.
+
+ For SMMUv2 implementations, there must be exactly one
+ interrupt per context bank. In the case of a single,
+ combined interrupt, it must be listed multiple times.
+
+- mmu-masters : A list of phandles to device nodes representing bus
+ masters for which the SMMU can provide a translation
+ and their corresponding StreamIDs (see example below).
+ Each device node linked from this list must have a
+ "#stream-id-cells" property, indicating the number of
+ StreamIDs associated with it.
+
+** System MMU optional properties:
+
+- smmu-parent : When multiple SMMUs are chained together, this
+ property can be used to provide a phandle to the
+ parent SMMU (that is the next SMMU on the path going
+ from the mmu-masters towards memory) node for this
+ SMMU.
+
+Example:
+
+ smmu {

+ #global-interrupts = <2>;
+ interrupts = <0 32 4>,

+Marvell Orion/Discovery ethernet controller
+=============================================
+
+The Marvell Discovery ethernet controller can be found on Marvell Orion SoCs
+(Kirkwood, Dove, Orion5x, and Discovery Innovation) and as part of Marvell
+Discovery system controller chips (mv64[345]60).
+
+The Discovery ethernet controller is described with two levels of nodes. The
+first level describes the ethernet controller itself and the second level
+describes up to 3 ethernet port nodes within that controller. The reason for
+the multiple levels is that the port registers are interleaved within a single
+set of controller registers. Each port node describes port-specific properties.
+
+Note: The above separation is only true for Discovery system controllers.
+For Orion SoCs we stick to the separation, although there each controller has
+only one port associated. Multiple ports are implemented as multiple single-port
+controllers. As Kirkwood has some issues with proper initialization after reset,
+an extra compatible string is added for it.
+
+* Ethernet controller node
+
+Required controller properties:
+ - #address-cells: shall be 1.
+ - #size-cells: shall be 0.
+ - compatible: shall be one of "marvell,orion-eth", "marvell,kirkwood-eth".
+ - reg: address and length of the controller registers.
+
+Optional controller properties:
+ - clocks: phandle reference to the controller clock.
+ - marvell,tx-checksum-limit: max tx packet size for hardware checksum.
+
+* Ethernet port node
+
+Required port properties:
+ - device_type: shall be "network".
+ - compatible: shall be one of "marvell,orion-eth-port",
+ "marvell,kirkwood-eth-port".
+ - reg: port number relative to ethernet controller, shall be 0, 1, or 2.
+ - interrupts: port interrupt.
+ - local-mac-address: 6 bytes MAC address.
+
+Optional port properties:
+ - marvell,tx-queue-size: size of the transmit ring buffer.
+ - marvell,tx-sram-addr: address of transmit descriptor buffer located in SRAM.
+ - marvell,tx-sram-size: size of transmit descriptor buffer located in SRAM.
+ - marvell,rx-queue-size: size of the receive ring buffer.
+ - marvell,rx-sram-addr: address of receive descriptor buffer located in SRAM.
+ - marvell,rx-sram-size: size of receive descriptor buffer located in SRAM.
+
+and
+
+ - phy-handle: phandle reference to ethernet PHY.
+
+or
+
+ - speed: port speed if no PHY connected.
+ - duplex: port mode if no PHY connected.
+
+* Node example:
+
+mdio-bus {
+ ...
+ ethphy: ethernet-phy@8 {
+ device_type = "ethernet-phy";
+ ...
+ };
+};
+
+eth: ethernet-controller@72000 {

+ Linux Gamepad API
+----------------------------------------------------------------------------
+
+1. Intro
+~~~~~~~~
+Linux provides many different input drivers for gamepad hardware. To avoid
+having user-space deal with different button-mappings for each gamepad, this
+document defines how gamepads are supposed to report their data.
+
+2. Geometry
+~~~~~~~~~~~
+As "gamepad" we define devices which roughly look like this:
+
+ ____________________________ __
+ / [__ZL__] [__ZR__] \ |
+ / [__ TL __] [__ TR __] \ | Front Triggers
+ __/________________________________\__ __|

+ | / \ |
+ \_____/ \_____/
+
+ |________|______| |______|___________|
+ D-Pad Left Right Action Pad
+ Stick Stick
+
+ |_____________|
+ Menu Pad
+
+Most gamepads have the following features:
+ - Action-Pad
+ 4 buttons in diamonds-shape (on the right side). The buttons are
+ differently labeled on most devices so we define them as NORTH,
+ SOUTH, WEST and EAST.
+ - D-Pad (Direction-pad)
+ 4 buttons (on the left side) that point up, down, left and right.
+ - Menu-Pad
+ Different constellations, but most-times 2 buttons: SELECT - START
+ Furthermore, many gamepads have a fancy branded button that is used as
+ special system-button. It often looks different to the other buttons and
+ is used to pop up system-menus or system-settings.
+ - Analog-Sticks
+ Analog-sticks provide freely moveable sticks to control directions. Not
+ all devices have both or any, but they are present at most times.
+ Analog-sticks may also provide a digital button if you press them.
+ - Triggers
+ Triggers are located on the upper-side of the pad in vertical direction.
+ Not all devices provide them, but the upper buttons are normally named
+ Left- and Right-Triggers, the lower buttons Z-Left and Z-Right.
+ - Rumble
+ Many devices provide force-feedback features. But are mostly just
+ simple rumble motors.
+
+3. Detection
+~~~~~~~~~~~~
+All gamepads that follow the protocol described here map BTN_GAMEPAD. This is
+an alias for BTN_SOUTH/BTN_A. It can be used to identify a gamepad as such.
+However, not all gamepads provide all features, so you need to test for all
+features that you need, first. How each feature is mapped is described below.
+
+Legacy drivers often don't comply to these rules. As we cannot change them
+for backwards-compatibility reasons, you need to provide fixup mappings in
+user-space yourself. Some of them might also provide module-options that
+change the mappings so you can adivce users to set these.
+
+All new gamepads are supposed to comply with this mapping. Please report any
+bugs, if they don't.
+
+There are a lot of less-featured/less-powerful devices out there, which re-use
+the buttons from this protocol. However, they try to do this in a compatible
+fashion. For example, the "Nintendo Wii Nunchuk" provides two trigger buttons
+and one analog stick. It reports them as if it were a gamepad with only one
+analog stick and two trigger buttons on the right side.
+But that means, that if you only support "real" gamepads, you must test
+devices for _all_ reported events that you need. Otherwise, you will also get
+devices that report a small subset of the events.
+
+No other devices, that do not look/feel like a gamepad, shall report these
+events.
+
+4. Events
+~~~~~~~~~
+Gamepads report the following events:
+
+Action-Pad:
+ Every gamepad device has at least 2 action buttons. This means, that every
+ device reports BTN_SOUTH (which BTN_GAMEPAD is an alias for). Regardless
+ of the labels on the buttons, the codes are sent according to the
+ physical position of the buttons.
+ Please note that 2- and 3-button pads are fairly rare and old. You might
+ want to filter gamepads that do not report all four.
+ 2-Button Pad:
+ If only 2 action-buttons are present, they are reported as BTN_SOUTH and
+ BTN_EAST. For vertical layouts, the upper button is BTN_EAST. For
+ horizontal layouts, the button more on the right is BTN_EAST.
+ 3-Button Pad:
+ If only 3 action-buttons are present, they are reported as (from left
+ to right): BTN_WEST, BTN_SOUTH, BTN_EAST
+ If the buttons are aligned perfectly vertically, they are reported as
+ (from top down): BTN_WEST, BTN_SOUTH, BTN_EAST
+ 4-Button Pad:
+ If all 4 action-buttons are present, they can be aligned in two
+ different formations. If diamond-shaped, they are reported as BTN_NORTH,
+ BTN_WEST, BTN_SOUTH, BTN_EAST according to their physical location.
+ If rectangular-shaped, the upper-left button is BTN_NORTH, lower-left
+ is BTN_WEST, lower-right is BTN_SOUTH and upper-right is BTN_EAST.
+
+D-Pad:
+ Every gamepad provides a D-Pad with four directions: Up, Down, Left, Right
+ Some of these are available as digital buttons, some as analog buttons. Some
+ may even report both. The kernel does not convert between these so
+ applications should support both and choose what is more appropriate if
+ both are reported.
+ Digital buttons are reported as:
+ BTN_DPAD_*
+ Analog buttons are reported as:
+ ABS_HAT0X and ABS_HAT0Y
+
+Analog-Sticks:
+ The left analog-stick is reported as ABS_X, ABS_Y. The right analog stick is
+ reported as ABS_RX, ABS_RY. Zero, one or two sticks may be present.
+ If analog-sticks provide digital buttons, they are mapped accordingly as
+ BTN_THUMBL (first/left) and BTN_THUMBR (second/right).
+
+Triggers:
+ Trigger buttons can be available as digital or analog buttons or both. User-
+ space must correctly deal with any situation and choose the most appropriate
+ mode.
+ Upper trigger buttons are reported as BTN_TR or ABS_HAT1X (right) and BTN_TL
+ or ABS_HAT1Y (left). Lower trigger buttons are reported as BTN_TR2 or
+ ABS_HAT2X (right/ZR) and BTN_TL2 or ABS_HAT2Y (left/ZL).
+ If only one trigger-button combination is present (upper+lower), they are
+ reported as "right" triggers (BTN_TR/ABS_HAT1X).
+
+Menu-Pad:
+ Menu buttons are always digital and are mapped according to their location
+ instead of their labels. That is:
+ 1-button Pad: Mapped as BTN_START
+ 2-button Pad: Left button mapped as BTN_SELECT, right button mapped as
+ BTN_START
+ Many pads also have a third button which is branded or has a special symbol
+ and meaning. Such buttons are mapped as BTN_MODE. Examples are the Nintendo
+ "HOME" button, the XBox "X"-button or Sony "P" button.
+
+Rumble:
+ Rumble is adverticed as FF_RUMBLE.

-1.2 Install ifenslave Control Utility
+1.2 Bonding Control Utility
-------------------------------------
- The ifenslave user level control program is included in the
-kernel source tree, in the file Documentation/networking/ifenslave.c.
-It is generally recommended that you use the ifenslave that
-corresponds to the kernel that you are using (either from the same
-source tree or supplied with the distro), however, ifenslave
-executables from older kernels should function (but features newer
-than the ifenslave release are not supported). Running an ifenslave
-that is newer than the kernel is not supported, and may or may not
-work.
-
- To install ifenslave, do the following:
-
-# gcc -Wall -O -I/usr/src/linux/include ifenslave.c -o ifenslave
-# cp ifenslave /sbin/ifenslave
-
- If your kernel source is not in "/usr/src/linux," then replace
-"/usr/src/linux/include" in the above with the location of your kernel
-source include directory.
-
- You may wish to back up any existing /sbin/ifenslave, or, for
-testing or informal use, tag the ifenslave to the kernel version
-(e.g., name the ifenslave executable /sbin/ifenslave-2.6.10).
-
-IMPORTANT NOTE:
-
- If you omit the "-I" or specify an incorrect directory, you
-may end up with an ifenslave that is incompatible with the kernel
-you're trying to build it for. Some distros (e.g., Red Hat from 7.1
-onwards) do not have /usr/include/linux symbolically linked to the
-default kernel source include directory.
-
-SECOND IMPORTANT NOTE:
- If you plan to configure bonding using sysfs or using the
-/etc/network/interfaces file, you do not need to use ifenslave.
+ It is recommended to configure bonding via iproute2 (netlink)
+or sysfs, the old ifenslave control utility is obsolete.

- *
- * Changes :
- * - 2000/10/02 Willy Tarreau <willy at meta-x.org> :
- * - few fixes. Master's MAC address is now correctly taken from
- * the first device when not previously set ;
- * - detach support : call BOND_RELEASE to detach an enslaved interface.
- * - give a mini-howto from command-line help : # ifenslave -h
- *
- * - 2001/02/16 Chad N. Tindel <ctindel at ieee dot org> :
- * - Master is now brought down before setting the MAC address. In
- * the 2.4 kernel you can't change the MAC address while the device is
- * up because you get EBUSY.
- *
- * - 2001/09/13 Takao Indoh <indou dot takao at jp dot fujitsu dot com>
- * - Added the ability to change the active interface on a mode 1 bond
- * at runtime.
- *
- * - 2001/10/23 Chad N. Tindel <ctindel at ieee dot org> :
- * - No longer set the MAC address of the master. The bond device will
- * take care of this itself
- * - Try the SIOC*** versions of the bonding ioctls before using the
- * old versions
- * - 2002/02/18 Erik Habbinga <erik_habbinga @ hp dot com> :
- * - ifr2.ifr_flags was not initialized in the hwaddr_notset case,
- * SIOCGIFFLAGS now called before hwaddr_notset test
- *
- * - 2002/10/31 Tony Cureington <tony.cureington * hp_com> :
- * - If the master does not have a hardware address when the first slave
- * is enslaved, the master is assigned the hardware address of that
- * slave - there is a comment in bonding.c stating "ifenslave takes
- * care of this now." This corrects the problem of slaves having
- * different hardware addresses in active-backup mode when
- * multiple interfaces are specified on a single ifenslave command
- * (ifenslave bond0 eth0 eth1).
- *
- * - 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
- * Shmulik Hen <shmulik.hen at intel dot com>
- * - Moved setting the slave's mac address and openning it, from
- * the application to the driver. This enables support of modes
- * that need to use the unique mac address of each slave.
- * The driver also takes care of closing the slave and restoring its
- * original mac address upon release.
- * In addition, block possibility of enslaving before the master is up.
- * This prevents putting the system in an undefined state.
- *
- * - 2003/05/01 - Amir Noam <amir.noam at intel dot com>
- * - Added ABI version control to restore compatibility between
- * new/old ifenslave and new/old bonding.
- * - Prevent adding an adapter that is already a slave.
- * Fixes the problem of stalling the transmission and leaving
- * the slave in a down state.
- *
- * - 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Prevent enslaving if the bond device is down.
- * Fixes the problem of leaving the system in unstable state and
- * halting when trying to remove the module.
- * - Close socket on all abnormal exists.
- * - Add versioning scheme that follows that of the bonding driver.
- * current version is 1.0.0 as a base line.
- *
- * - 2003/05/22 - Jay Vosburgh <fubar at us dot ibm dot com>
- * - ifenslave -c was broken; it's now fixed
- * - Fixed problem with routes vanishing from master during enslave
- * processing.
- *
- * - 2003/05/27 - Amir Noam <amir.noam at intel dot com>
- * - Fix backward compatibility issues:
- * For drivers not using ABI versions, slave was set down while
- * it should be left up before enslaving.
- * Also, master was not set down and the default set_mac_address()
- * would fail and generate an error message in the system log.
- * - For opt_c: slave should not be set to the master's setting
- * while it is running. It was already set during enslave. To
- * simplify things, it is now handled separately.
- *
- * - 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Code cleanup and style changes
- * set version to 1.1.0

RPS might be beneficial if the rps_cpus for each queue are the ones that
share the same memory domain as the interrupting CPU for that queue.
+==== RPS Flow Limit
+
+RPS scales kernel receive processing across CPUs without introducing
+reordering. The trade-off to sending all packets from the same flow
+to the same CPU is CPU load imbalance if flows vary in packet rate.
+In the extreme case a single flow dominates traffic. Especially on
+common server workloads with many concurrent connections, such
+behavior indicates a problem such as a misconfiguration or spoofed
+source Denial of Service attack.
+
+Flow Limit is an optional RPS feature that prioritizes small flows
+during CPU contention by dropping packets from large flows slightly
+ahead of those from small flows. It is active only when an RPS or RFS
+destination CPU approaches saturation. Once a CPU's input packet
+queue exceeds half the maximum queue length (as set by sysctl
+net.core.netdev_max_backlog), the kernel starts a per-flow packet
+count over the last 256 packets. If a flow exceeds a set ratio (by
+default, half) of these packets when a new packet arrives, then the
+new packet is dropped. Packets from other flows are still only
+dropped once the input packet queue reaches netdev_max_backlog.
+No packets are dropped when the input packet queue length is below
+the threshold, so flow limit does not sever connections outright:
+even large flows maintain connectivity.
+
+== Interface
+
+Flow limit is compiled in by default (CONFIG_NET_FLOW_LIMIT), but not
+turned on. It is implemented for each CPU independently (to avoid lock
+and cache contention) and toggled per CPU by setting the relevant bit
+in sysctl net.core.flow_limit_cpu_bitmap. It exposes the same CPU
+bitmap interface as rps_cpus (see above) when called from procfs:
+
+ /proc/sys/net/core/flow_limit_cpu_bitmap
+
+Per-flow rate is calculated by hashing each packet into a hashtable
+bucket and incrementing a per-bucket counter. The hash function is
+the same that selects a CPU in RPS, but as the number of buckets can
+be much larger than the number of CPUs, flow limit has finer-grained
+identification of large flows and fewer false positives. The default
+table has 4096 buckets. This value can be modified through sysctl
+
+ net.core.flow_limit_table_len
+
+The value is only consulted when a new table is allocated. Modifying
+it does not update active tables.
+
+== Suggested Configuration
+
+Flow limit is useful on systems with many concurrent connections,
+where a single connection taking up 50% of a CPU indicates a problem.
+In such environments, enable the feature on all CPUs that handle
+network rx interrupts (as set in /proc/irq/N/smp_affinity).
+
+The feature depends on the input packet queue length to exceed
+the flow limit threshold (50%) + the flow history length (256).
+Setting net.core.netdev_max_backlog to either 1000 or 10000
+performed well in experiments.

+If CONFIG_SYSFS is enabled in your kernel configuration a simple sysfs
+interface is provided to use the PWMs from userspace. It is exposed at
+/sys/class/pwm/. Each probed PWM controller/chip will be exported as
+pwmchipN, where N is the base of the PWM chip. Inside the directory you

+
+export - Exports a PWM channel for use with sysfs (write-only).
+
+unexport - Unexports a PWM channel from sysfs (write-only).
+
+The PWM channels are numbered using a per-chip index from 0 to npwm-1.
+
+When a PWM channel is exported a pwmX directory will be created in the
+pwmchipN directory it is associated with, where X is the number of the
+channel that was exported. The following properties will then be available:
+
+period - The total period of the PWM signal (read/write).

+polarity - Changes the polarity of the PWM signal (read/write).
+ Writes to this property only work if the PWM chip supports changing
+ the polarity. The polarity can only be changed if the PWM is not
+ enabled. Value is the string "normal" or "inversed".

+Chapter 14.6: PACKAGE LEVEL THERMAL MANAGEMENT
+
+Description
+---------
+
+This driver register CPU digital temperature package level sensor as a thermal
+zone with maximum two user mode configurable trip points. Number of trip points
+depends on the capability of the package. Once the trip point is violated,
+user mode can receive notification via thermal notification mechanism and can
+take any action to control temperature.
+
+
+Threshold management
+--------------------
+Each package will register as a thermal zone under /sys/class/thermal.
+Example:
+/sys/class/thermal/thermal_zone1
+
+This contains two trip points:
+- trip_point_0_temp
+- trip_point_1_temp
+
+User can set any temperature between 0 to TJ-Max temperature. Temperature units
+are in milli-degree Celsius. Refer to "Documentation/thermal/sysfs-api.txt" for
+thermal sys-fs details.
+
+Any value other than 0 in these trip points, can trigger thermal notifications.
+Setting 0, stops sending thermal notifications.
+
+Thermal notifications: To get kobject-uevent notifications, set the thermal zone
+policy to "user_space". For example: echo -n "user_space" > policy

+V4L2 clocks
+-----------
+
+Many subdevices, like camera sensors, TV decoders and encoders, need a clock
+signal to be supplied by the system. Often this clock is supplied by the
+respective bridge device. The Linux kernel provides a Common Clock Framework for
+this purpose. However, it is not (yet) available on all architectures. Besides,
+the nature of the multi-functional (clock, data + synchronisation, I2C control)
+connection of subdevices to the system might impose special requirements on the
+clock API usage. E.g. V4L2 has to support clock provider driver unregistration
+while a subdevice driver is holding a reference to the clock. For these reasons
+a V4L2 clock helper API has been developed and is provided to bridge and
+subdevice drivers.
+
+The API consists of two parts: two functions to register and unregister a V4L2
+clock source: v4l2_clk_register() and v4l2_clk_unregister() and calls to control
+a clock object, similar to the respective generic clock API calls:
+v4l2_clk_get(), v4l2_clk_put(), v4l2_clk_enable(), v4l2_clk_disable(),
+v4l2_clk_get_rate(), and v4l2_clk_set_rate(). Clock suppliers have to provide
+clock operations that will be called when clock users invoke respective API
+methods.
+
+It is expected that once the CCF becomes available on all relevant
+architectures this API will be removed.

+Overview:
+
+Zswap is a lightweight compressed cache for swap pages. It takes pages that are
+in the process of being swapped out and attempts to compress them into a
+dynamically allocated RAM-based memory pool. zswap basically trades CPU cycles
+for potentially reduced swap I/O.  This trade-off can also result in a
+significant performance improvement if reads from the compressed cache are
+faster than reads from a swap device.
+
+NOTE: Zswap is a new feature as of v3.11 and interacts heavily with memory
+reclaim. This interaction has not be fully explored on the large set of
+potential configurations and workloads that exist. For this reason, zswap
+is a work in progress and should be considered experimental.
+
+Some potential benefits:
+* Desktop/laptop users with limited RAM capacities can mitigate the
+    performance impact of swapping.
+* Overcommitted guests that share a common I/O resource can
+    dramatically reduce their swap I/O pressure, avoiding heavy handed I/O
+ throttling by the hypervisor. This allows more work to get done with less
+ impact to the guest workload and guests sharing the I/O subsystem
+* Users with SSDs as swap devices can extend the life of the device by
+    drastically reducing life-shortening writes.
+
+Zswap evicts pages from compressed cache on an LRU basis to the backing swap
+device when the compressed pool reaches it size limit. This requirement had
+been identified in prior community discussions.
+
+To enabled zswap, the "enabled" attribute must be set to 1 at boot time. e.g.
+zswap.enabled=1
+
+Design:
+
+Zswap receives pages for compression through the Frontswap API and is able to
+evict pages from its own compressed pool on an LRU basis and write them back to
+the backing swap device in the case that the compressed pool is full.
+
+Zswap makes use of zbud for the managing the compressed memory pool. Each
+allocation in zbud is not directly accessible by address. Rather, a handle is
+return by the allocation routine and that handle must be mapped before being
+accessed. The compressed memory pool grows on demand and shrinks as compressed
+pages are freed. The pool is not preallocated.
+
+When a swap page is passed from frontswap to zswap, zswap maintains a mapping
+of the swap entry, a combination of the swap type and swap offset, to the zbud
+handle that references that compressed swap page. This mapping is achieved
+with a red-black tree per swap type. The swap offset is the search key for the
+tree nodes.
+
+During a page fault on a PTE that is a swap entry, frontswap calls the zswap
+load function to decompress the page into the page allocated by the page fault
+handler.
+
+Once there are no PTEs referencing a swap page stored in zswap (i.e. the count
+in the swap_map goes to 0) the swap code calls the zswap invalidate function,
+via frontswap, to free the compressed entry.
+
+Zswap seeks to be simple in its policies. Sysfs attributes allow for one user
+controlled policies:
+* max_pool_percent - The maximum percentage of memory that the compressed
+ pool can occupy.
+
+Zswap allows the compressor to be selected at kernel boot time by setting the
+“compressor†attribute. The default compressor is lzo. e.g.
+zswap.compressor=deflate
+
+A debugfs interface is provided for various statistic about pool size, number
+of pages stored, and various counters for the reasons pages are rejected.

- * Similar to the Alpha and MIPS ports, we need to keep track of the ref
- * and mod bits in software. We have a software "you can read
- * from this page" bit, and a hardware one which actually lets the
- * process read from the page. On the same token we have a software
- * writable bit and the real hardware one which actually lets the
- * process write to the page.
+ * Legend:
+ * PPN Physical Page Number
+ * ADW software: accessed (young) / dirty / writable
+ * RI ring (0=privileged, 1=user, 2 and 3 are unused)
+ * CA cache attribute: 00 bypass, 01 writeback, 10 writethrough
+ * (11 is invalid and used to mark pages that are not present)
+ * w page is writable (hw)
+ * x page is executable (hw)
+ * index swap offset / PAGE_SIZE (bit 11-31: 21 bits -> 8 GB)
+ * (note that the index is always non-zero)
+ * type swap type (5 bits -> 32 types)
+ * file offset 26-bit offset into the file, in increments of PAGE_SIZE
*
- * See further below for PTE layout for swapped-out pages.
+ * Notes:
+ * - (PROT_NONE) is a special case of 'present' but causes an exception for
+ * any access (read, write, and execute).
+ * - 'multihit-exception' has the highest priority of all MMU exceptions,
+ * so the ring must be set to 'RING_USER' even for 'non-present' pages.
+ * - on older hardware, the exectuable flag was not supported and
+ * used as a 'valid' flag, so it needs to be always set.
+ * - we need to keep track of certain flags in software (dirty and young)
+ * to do this, we use write exceptions and have a separate software w-flag.
+ * - attribute value 1101 (and 1111 on T1050 and earlier) is reserved

+ VBIOS will set up proper PWM frequency and ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1,as the result,
+ Changing BL using VBIOS function is functional in both driver and non-driver present environment;
+ and enabling VariBri under the driver environment from PP table is optional.
+
+ 2. SW uses other means to control BL (like DPCD),this non-zero frequency serves as a flag only indicating
+ that BL control from GPU is expected.
+ VBIOS will NOT set up PWM frequency but make ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1
+ Changing BL using VBIOS function could be functional in both driver and non-driver present environment,but
+ it's per platform
+ and enabling VariBri under the driver environment from PP table is optional.

+ * DMA engines. These engines are used for compute
+ * and gfx. There are two DMA engines (SDMA0, SDMA1)
+ * and each one supports 1 ring buffer used for gfx
+ * and 2 queues used for compute.
+ *
+ * The programming model is very similar to the CP
+ * (ring buffer, IBs, etc.), but sDMA has it's own
+ * packet format that is different from the PM4 format
+ * used by the CP. sDMA supports copying data, writing
+ * embedded data, solid fills, and a number of other
+ * things. It also has support for tiling/detiling of
+ * buffers.

+ * SoC, known as the "Security Processor" (SP) or "Wireless Trusted Module"
+ * (WTM). This firmware then reports its results via the WTM registers,
+ * which we read from the Application Processor (AP, i.e. main CPU) in this
+ * driver.
+ *
+ * On the hardware side we have a PS/2 mouse and an AT keyboard, the data

+ * Bootloader Messaging Interface (BMI)
+ *
+ * BMI is a very simple messaging interface used during initialization
+ * to read memory, write memory, execute code, and to define an
+ * application entry PC.
+ *
+ * It is used to download an application to QCA988x, to provide
+ * patches to code that is already resident on QCA988x, and generally
+ * to examine and modify state. The Host has an opportunity to use
+ * BMI only once during bootup. Once the Host issues a BMI_DONE
+ * command, this opportunity ends.
+ *
+ * The Host writes BMI requests to mailbox0, and reads BMI responses
+ * from mailbox0. BMI requests all begin with a command
+ * (see below for specific commands), and are followed by
+ * command-specific data.
+ *
+ * Flow control:
+ * The Host can only issue a command once the Target gives it a
+ * "BMI Command Credit", using AR8K Counter #4. As soon as the
+ * Target has completed a command, it issues another BMI Command
+ * Credit (so the Host can issue the next command).
+ *
+ * BMI handles all required Target-side cache flushing.

+ * A single CopyEngine (CE) comprises two "rings":
+ * a source ring
+ * a destination ring
+ *
+ * Each ring consists of a number of descriptors which specify
+ * an address, length, and meta-data.
+ *
+ * Typically, one side of the PCIe interconnect (Host or Target)
+ * controls one ring and the other side controls the other ring.
+ * The source side chooses when to initiate a transfer and it
+ * chooses what to send (buffer address, length). The destination
+ * side keeps a supply of "anonymous receive buffers" available and
+ * it handles incoming data as it arrives (when the destination
+ * recieves an interrupt).
+ *
+ * The sender may send a simple buffer (address/length) or it may
+ * send a small list of buffers. When a small list is sent, hardware
+ * "gathers" these and they end up in a single destination buffer
+ * with a single interrupt.
+ *
+ * There are several "contexts" managed by this layer -- more, it
+ * may seem -- than should be needed. These are provided mainly for
+ * maximum flexibility and especially to facilitate a simpler HIF
+ * implementation. There are per-CopyEngine recv, send, and watermark
+ * contexts. These are supplied by the caller when a recv, send,
+ * or watermark handler is established and they are echoed back to
+ * the caller when the respective callbacks are invoked. There is
+ * also a per-transfer context supplied by the caller when a buffer
+ * (or sendlist) is sent and when a buffer is enqueued for recv.
+ * These per-transfer contexts are echoed back to the caller when
+ * the buffer is sent/received.

+ * We could probably try using tim_bitmap from SWBA to tell

+ * problem here is calling mac80211 functions so many times
+ * could take too long and make us miss the time to submit

+ *
+ * It includes definitions of all the commands and events. Commands are
+ * messages from the host to the target. Events and Replies are messages
+ * from the target to the host.
+ *
+ * Ownership of correctness in regards to WMI commands belongs to the host
+ * driver and the target is not required to validate parameters for value,
+ * proper range, or any other checking.
+ *
+ * Guidelines for extending this interface are below.
+ *
+ * 1. Add new WMI commands ONLY within the specified range - 0x9000 - 0x9fff
+ *
+ * 2. Use ONLY u32 type for defining member variables within WMI
+ * command/event structures. Do not use u8, u16, bool or
+ * enum types within these structures.
+ *
+ * 3. DO NOT define bit fields within structures. Implement bit fields
+ * using masks if necessary. Do not use the programming language's bit
+ * field definition.
+ *
+ * 4. Define macros for encode/decode of u8, u16 fields within
+ * the u32 variables. Use these macros for set/get of these fields.
+ * Try to use this to optimize the structure without bloating it with
+ * u32 variables for every lower sized field.
+ *
+ * 5. Do not use PACK/UNPACK attributes for the structures as each member
+ * variable is already 4-byte aligned by virtue of being a u32
+ * type.
+ *
+ * 6. Comment each parameter part of the WMI command/event structure by
+ * using the 2 stars at the begining of C comment instead of one star to
+ * enable HTML document generation using Doxygen.

+# lpfc_max_luns: maximum allowed LUN ID. This is the highest LUN ID that
+# will be scanned by the SCSI midlayer when sequential scanning is
+# used; and is also the highest LUN ID allowed when the SCSI midlayer
+# parses REPORT_LUN responses. The lpfc driver has no LUN count or
+# LUN ID limit, but the SCSI midlayer requires this field for the uses
+# above. The lpfc driver limits the default value to 255 for two reasons.
+# As it bounds the sequential scan loop, scanning for thousands of luns
+# on a target can take minutes of wall clock time. Additionally,
+# there are FC targets, such as JBODs, that only recognize 8-bits of
+# LUN ID. When they receive a value greater than 8 bits, they chop off
+# the high order bits. In other words, they see LUN IDs 0, 256, 512,
+# and so on all as LUN ID 0. This causes the linux kernel, which sees
+# valid responses at each of the LUN IDs, to believe there are multiple
+# devices present, when in fact, there is only 1.
+# A customer that is aware of their target behaviors, and the results as
+# indicated above, is welcome to increase the lpfc_max_luns value.
+# As mentioned, this value is not used by the lpfc driver, only the

-NAME
- CsrTimeGet
-
-DESCRIPTION
- Returns the current system time in a low and a high part. The low part
- is expressed in microseconds. The high part is incremented when the low
- part wraps to provide an extended range.
-
- The caller may provide a NULL pointer as the high parameter.
- In this case the function just returns the low part and ignores the
- high parameter.
-
- Although the time is expressed in microseconds the actual resolution is
- platform dependent and can be less. It is recommended that the
- resolution is at least 10 milliseconds.
-
-PARAMETERS
- high - Pointer to variable that will receive the high part of the
- current system time. Passing NULL is valid.
-
-RETURNS
- Low part of current system time in microseconds.

-/*
- * - Function ----------------------------------------------------------------
- * card_hw_init()
- *
- * Perform the initialisation procedure described in the UniFi Host
- * Interface Protocol document (section 3.3.8) and read the run-time
- * configuration information from the UniFi. This is stuff like number
- * of bulk data slots etc.
- *
- * The card enumeration and SD initialisation has already been done by
- * the SDIO library, see card_sdio_init().
- *
- * The initialisation is done when firmware is ready, i.e. this may need
- * to be called after a f/w download operation.
- *
- * The initialisation procedure goes like this:
- * - Wait for UniFi to start-up by polling SHARED_MAILBOX1
- * - Find the symbol table and look up SLT_SDIO_SLOT_CONFIG
- * - Read the config structure
- * - Check the "SDIO initialised" flag, if not zero do a h/w reset and
- * start again
- * - Decide the number of bulk data slots to allocate, allocate them and
- * set "SDIO initialised" flag (and generate an interrupt) to say so.
- *
- * Arguments:
- * card Pointer to card struct
- *
- * Returns:
- * CSR_RESULT_SUCEESS on success,
- * a CSR error code on failure
- *
- * Notes:
- * All data in the f/w is stored in a little endian format, without any
- * padding bytes. Every read from this memory has to be transformed in
- * host (cpu specific) format, before it is stored in driver's parameters
- * or/and structures. Athough unifi_card_read16() and unifi_read32() do perform
- * the conversion internally, unifi_readn() does not.

- * slots that this queue can actually use (may be higher than reserved slots and is dependent on reserved slots

- * unreserved slots sufficient for this request. If available these slots are reserved for the queue.
- * If there are not enough unreserved slots, a fair share for each queue is calculated based on the total slots
- * and the number of active queues (any queue with existing reservation is considered active). Queues needing
- * less than their fair share are allowed to have the previously reserved slots. The remaining slots are
- * distributed evenly among queues that need more than the fair share

- * A better scheme would take current bandwidth per AC into consideration when reserving slots. An
- * implementation scheme could consider the relative time/service period for slots in an AC. If the firmware

- * - there are less than UNIFI_MAX_DATA_REFERENCES (2) bulk data
- * slots available.
- *
- * Arguments:

- * sigptr Pointer to the signal to write to UniFi.
- * siglen Number of bytes pointer to by sigptr.
- * bulkdata Array of pointers to an associated bulk data.

- *
- * Returns:

- * But to avoid this deadlock completely, after setting the flag we check that there is something left in the queue.
- * If there is, we know that bh thread has not emptied the queue yet.
- * Since bh thread checks to unpause the queue *after* taking packets from the queue, we know that it is still going to make at

- of the frame in question.
- If the cancellation fails, the Router will send, if required,
- CsrWifiRouterMaPacketCfm.
- If the cancellation succeeds, the Router will not send
- CsrWifiRouterMaPacketCfm.
-
- PARAMETERS
- queue - Message Source Task Queue (Cfm's will be sent to this Queue)
- interfaceTag - Interface Identifier; unique identifier of an interface
- hostTag - The hostTag for the frame, which should be cancelled.

-
- NAME
- CsrWifiSmeConnectReqSend
-
- DESCRIPTION
- The wireless manager application calls this primitive to start the
- process of joining an 802.11 wireless network or to start an ad hoc
- network.
- The structure pointed by connectionConfig contains parameters describing
- the network to join or, in case of an ad hoc network, to host or join.
- The SME will select a network, perform the IEEE 802.11 Join, Authenticate
- and Associate exchanges.
- The SME selects the networks from the current scan list that match both
- the SSID and BSSID, however either or both of these may be the wildcard
- value. Using this rule, the following operations are possible:
- * To connect to a network by name, specify the SSID and set the BSSID to
- 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. If there are two or more networks visible,
- the SME will select the one with the strongest signal.
- * To connect to a specific network, specify the BSSID. The SSID is
- optional, but if given it must match the SSID of the network. An empty
- SSID may be specified by setting the SSID length to zero. Please note
- that if the BSSID is specified (i.e. not equal to 0xFF 0xFF 0xFF 0xFF
- 0xFF 0xFF), the SME will not attempt to roam if signal conditions become
- poor, even if there is an alternative AP with an SSID that matches the
- current network SSID.
- * To connect to any network matching the other parameters (i.e. security,
- etc), set the SSID length to zero and set the BSSID to 0xFF 0xFF 0xFF
- 0xFF 0xFF 0xFF. In this case, the SME will order all available networks
- by their signal strengths and will iterate through this list until it
- successfully connects.
- NOTE: Specifying the BSSID will restrict the selection to one specific
- network. If SSID and BSSID are given, they must both match the network
- for it to be selected. To select a network based on the SSID only, the
- wireless manager application must set the BSSID to 0xFF 0xFF 0xFF 0xFF
- 0xFF 0xFF.
- The SME will try to connect to each network that matches the provided
- parameters, one by one, until it succeeds or has tried unsuccessfully
- with all the matching networks.
- If there is no network that matches the parameters and the request allows
- to host an ad hoc network, the SME will advertise a new ad hoc network
- instead.
- If the SME cannot connect, it will notify the failure in the confirm.
-
- PARAMETERS
- queue - Message Source Task Queue (Cfm's will be sent to this Queue)
- interfaceTag - Interface Identifier; unique identifier of an interface
- connectionConfig - Describes the candidate network to join or to host.

-
- DESCRIPTION
- The wireless manager application should call this primitive to enable or
- disable filtering of broadcast packets: uninteresting broadcast packets
- will be dropped by the Wi-Fi chip, instead of passing them up to the
- host.
- This has the advantage of saving power in the host application processor
- as it removes the need to process unwanted packets.
- All broadcast packets are filtered according to the filter and the filter
- mode provided, except ARP packets, which are filtered using
- arpFilterAddress.
- Filters are not cumulative: only the parameters specified in the most
- recent successful request are significant.
- For more information, see 'UniFi Firmware API Specification'.
-
- PARAMETERS
- queue - Message Source Task Queue (Cfm's will be sent to this Queue)
- interfaceTag - Interface Identifier; unique identifier of an interface
- filterLength - Length of the filter in bytes.
- filterLength=0 disables the filter previously set
- filter - Points to the first byte of the filter provided, if any.
- This shall include zero or more instance of the
- information elements of one of these types
- * Traffic Classification (TCLAS) elements
- * WMM-SA TCLAS elements
- mode - Specifies whether the filter selects or excludes packets
- matching the filter
- arpFilterAddress - IPv4 address to be used for filtering the ARP packets.
- * If the specified address is the IPv4 broadcast address
- (255.255.255.255), all ARP packets are reported to the
- host,
- * If the specified address is NOT the IPv4 broadcast
- address, only ARP packets with the specified address in

- NAME
- CsrWifiSmeRoamStartIndSend
-
- DESCRIPTION
- The SME will send this primitive to all the tasks that have registered to
- receive it whenever it begins an attempt to roam to an AP.
- If the wireless manager application connect request specified the SSID
- and the BSSID was set to the broadcast address (0xFF 0xFF 0xFF 0xFF 0xFF
- 0xFF), the SME monitors the signal quality and maintains a list of
- candidates to roam to. When the signal quality of the current connection
- falls below a threshold, and there is a candidate with better quality,
- the SME will attempt to the candidate AP.
- If the roaming procedure succeeds, the SME will also issue a Media
- Connect indication to inform the wireless manager application of the
- change.
- NOTE: to prevent the SME from initiating roaming the WMA must specify the
- BSSID in the connection request; this forces the SME to connect only to
- that AP.
- The wireless manager application can obtain statistics for roaming
- purposes using CSR_WIFI_SME_CONNECTION_QUALITY_IND and
- CSR_WIFI_SME_CONNECTION_STATS_GET_REQ.
- When the wireless manager application wishes to roam to another AP, it
- must issue a connection request specifying the BSSID of the desired AP.

- NAME
- CsrWifiSmeScanConfigSetReqSend
-
- DESCRIPTION
- This primitive sets the value of the ScanConfig parameter.
- The SME normally configures the firmware to perform autonomous scanning
- without involving the host.
- The firmware passes beacon / probe response or indicates loss of beacon
- on certain changes of state, for example:
- * A new AP is seen for the first time
- * An AP is no longer visible
- * The signal strength of an AP changes by more than a certain amount, as
- configured by the thresholds in the scanConfig parameter
- In addition to the autonomous scan, the wireless manager application may
- request a scan at any time using CSR_WIFI_SME_SCAN_FULL_REQ.

-
- NAME
- CsrWifiSmeScanFullReqSend
-
- DESCRIPTION
- The wireless manager application should call this primitive to request a
- full scan.
- Channels are scanned actively or passively according to the requirement
- set by regulatory domain.
- If the SME receives this primitive while a full scan is going on, the new
- request is buffered and it will be served after the current full scan is
- completed.
-
- PARAMETERS
- queue - Message Source Task Queue (Cfm's will be sent to this Queue)
- ssidCount - Number of SSIDs provided.
- If it is 0, the SME will attempt to detect any network
- ssid - Points to the first SSID provided, if any.
- bssid - BSS identifier.
- If it is equal to FF-FF-FF-FF-FF, the SME will listen for
- messages from any BSS.
- If it is different from FF-FF-FF-FF-FF and any SSID is
- provided, one SSID must match the network of the BSS.
- forceScan - Forces the scan even if the SME is in a state which would
- normally prevent it (e.g. autonomous scan is running).
- bssType - Type of BSS to scan for
- scanType - Type of scan to perform
- channelListCount - Number of channels provided.
- If it is 0, the SME will initiate a scan of all the
- supported channels that are permitted by the current
- regulatory domain.
- channelList - Points to the first channel , or NULL if channelListCount
- is zero.
- probeIeLength - Length of the information element in bytes to be sent
- with the probe message.
- probeIe - Points to the first byte of the information element to be
- sent with the probe message.

- The Wireless Manager calls this primitive to ask the SME to delete all

- Any time the Wireless Manager requests scan results, they are returned

- For some applications it may be desirable to clear this cache prior to
- requesting that a scan be performed; this will ensure that the cache then
- only contains the networks detected in the most recent scan.

-
- NAME
- CsrWifiSmeTspecReqSend
-
- DESCRIPTION
- The wireless manager application should call this primitive to use the
- TSPEC feature.
- The chip supports the use of TSPECs and TCLAS for the use of IEEE
- 802.11/WMM Quality of Service features.
- The API allows the wireless manager application to supply a correctly
- formatted TSPEC and TCLAS pair to the driver.
- After performing basic validation, the driver negotiates the installation
- of the TSPEC with the AP as defined by the 802.11 specification.
- The driver retains all TSPEC and TCLAS pairs until they are specifically
- removed.
- It is not compulsory for a TSPEC to have a TCLAS (NULL is used to
- indicate that no TCLAS is supplied), while a TCLASS always require a
- TSPEC.
- The format of the TSPEC element is specified in 'WMM (including WMM Power
- Save) Specification - Version 1.1' and 'ANSI/IEEE Std 802.11-REVmb/D3.0'.
- For more information, see 'UniFi Configuring WMM and WMM-PS'.
-
- PARAMETERS
- queue - Message Source Task Queue (Cfm's will be sent to this Queue)
- interfaceTag - Interface Identifier; unique identifier of an interface
- action - Specifies the action to be carried out on the list of TSPECs.
- CSR_WIFI_SME_LIST_ACTION_FLUSH is not applicable here.
- transactionId - Unique Transaction ID for the TSPEC, as assigned by the
- driver
- strict - If it set to false, allows the SME to perform automatic
- TSPEC negotiation
- ctrlMask - Additional TSPEC configuration for CCX.
- Set mask with values from CsrWifiSmeTspecCtrl.
- CURRENTLY NOT SUPPORTED
- tspecLength - Length of the TSPEC.
- tspec - Points to the first byte of the TSPEC
- tclasLength - Length of the TCLAS.
- If it is equal to 0, no TCLASS is provided for the TSPEC

-
- NAME
- CsrWifiSmeWifiFlightmodeReqSend
-
- DESCRIPTION
- The wireless manager application may call this primitive on boot-up of
- the platform to ensure that the chip is placed in a mode that prevents
- any emission of RF energy.
- This primitive is an alternative to CSR_WIFI_SME_WIFI_ON_REQ.
- As in CSR_WIFI_SME_WIFI_ON_REQ, it causes the download of the patch file
- (if any) and the programming of the initial MIB settings (if supplied by
- the WMA), but it also ensures that the chip is left in its lowest
- possible power-mode with the radio subsystems disabled.
- This feature is useful on platforms where power cannot be removed from
- the chip (leaving the chip not initialised will cause it to consume more
- power so calling this function ensures that the chip is initialised into
- a low power mode but without entering a state where it could emit any RF
- energy).
- NOTE: this primitive does not cause the Wi-Fi to change state: Wi-Fi
- stays conceptually off. Configuration primitives can be sent after
- CSR_WIFI_SME_WIFI_FLIGHTMODE_REQ and the configuration will be maintained.
- Requests that require the state of the Wi-Fi to be ON will return
- CSR_WIFI_SME_STATUS_WIFI_OFF in their confirms.
-
- PARAMETERS
- queue - Message Source Task Queue (Cfm's will be sent to this Queue)
- address - Optionally specifies a station MAC address.
- In normal use, the manager should set the address to 0xFF
- 0xFF 0xFF 0xFF 0xFF 0xFF, which will cause the chip to use
- the MAC address in the MIB.
- mibFilesCount - Number of provided data blocks with initial MIB values
- mibFiles - Points to the first data block with initial MIB values.
- These data blocks are typically the contents of the provided
- files ufmib.dat and localmib.dat, available from the host
- file system, if they exist.
- These files typically contain radio tuning and calibration
- values.
- More values can be created using the Host Tools.

-
- NAME
- CsrWifiSmeConnectReq
-
- DESCRIPTION
- The wireless manager application calls this primitive to start the
- process of joining an 802.11 wireless network or to start an ad hoc
- network.
- The structure pointed by connectionConfig contains parameters describing
- the network to join or, in case of an ad hoc network, to host or join.
- The SME will select a network, perform the IEEE 802.11 Join, Authenticate
- and Associate exchanges.
- The SME selects the networks from the current scan list that match both
- the SSID and BSSID, however either or both of these may be the wildcard
- value. Using this rule, the following operations are possible:
- * To connect to a network by name, specify the SSID and set the BSSID to
- 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. If there are two or more networks visible,
- the SME will select the one with the strongest signal.
- * To connect to a specific network, specify the BSSID. The SSID is
- optional, but if given it must match the SSID of the network. An empty
- SSID may be specified by setting the SSID length to zero. Please note
- that if the BSSID is specified (i.e. not equal to 0xFF 0xFF 0xFF 0xFF
- 0xFF 0xFF), the SME will not attempt to roam if signal conditions become
- poor, even if there is an alternative AP with an SSID that matches the
- current network SSID.
- * To connect to any network matching the other parameters (i.e. security,
- etc), set the SSID length to zero and set the BSSID to 0xFF 0xFF 0xFF
- 0xFF 0xFF 0xFF. In this case, the SME will order all available networks
- by their signal strengths and will iterate through this list until it
- successfully connects.
- NOTE: Specifying the BSSID will restrict the selection to one specific
- network. If SSID and BSSID are given, they must both match the network
- for it to be selected. To select a network based on the SSID only, the
- wireless manager application must set the BSSID to 0xFF 0xFF 0xFF 0xFF
- 0xFF 0xFF.
- The SME will try to connect to each network that matches the provided
- parameters, one by one, until it succeeds or has tried unsuccessfully
- with all the matching networks.
- If there is no network that matches the parameters and the request allows
- to host an ad hoc network, the SME will advertise a new ad hoc network
- instead.
- If the SME cannot connect, it will notify the failure in the confirm.

- The wireless manager application should call this primitive to use the

- 802.11/WMM Quality of Service features.
- The API allows the wireless manager application to supply a correctly

- After performing basic validation, the driver negotiates the installation
- of the TSPEC with the AP as defined by the 802.11 specification.
- The driver retains all TSPEC and TCLAS pairs until they are specifically
- removed.
- It is not compulsory for a TSPEC to have a TCLAS (NULL is used to
- indicate that no TCLAS is supplied), while a TCLASS always require a
- TSPEC.
- The format of the TSPEC element is specified in 'WMM (including WMM Power

-
- DESCRIPTION
- The wireless manager application may call this primitive on boot-up of
- the platform to ensure that the chip is placed in a mode that prevents
- any emission of RF energy.
- This primitive is an alternative to CSR_WIFI_SME_WIFI_ON_REQ.
- As in CSR_WIFI_SME_WIFI_ON_REQ, it causes the download of the patch file
- (if any) and the programming of the initial MIB settings (if supplied by
- the WMA), but it also ensures that the chip is left in its lowest
- possible power-mode with the radio subsystems disabled.
- This feature is useful on platforms where power cannot be removed from
- the chip (leaving the chip not initialised will cause it to consume more
- power so calling this function ensures that the chip is initialised into
- a low power mode but without entering a state where it could emit any RF
- energy).
- NOTE: this primitive does not cause the Wi-Fi to change state: Wi-Fi
- stays conceptually off. Configuration primitives can be sent after
- CSR_WIFI_SME_WIFI_FLIGHTMODE_REQ and the configuration will be maintained.
- Requests that require the state of the Wi-Fi to be ON will return
- CSR_WIFI_SME_STATUS_WIFI_OFF in their confirms.

- CsrWifiSmeRoamStartInd
-
- DESCRIPTION
- The SME will send this primitive to all the tasks that have registered to
- receive it whenever it begins an attempt to roam to an AP.
- If the wireless manager application connect request specified the SSID
- and the BSSID was set to the broadcast address (0xFF 0xFF 0xFF 0xFF 0xFF
- 0xFF), the SME monitors the signal quality and maintains a list of
- candidates to roam to. When the signal quality of the current connection
- falls below a threshold, and there is a candidate with better quality,
- the SME will attempt to the candidate AP.
- If the roaming procedure succeeds, the SME will also issue a Media
- Connect indication to inform the wireless manager application of the
- change.
- NOTE: to prevent the SME from initiating roaming the WMA must specify the
- BSSID in the connection request; this forces the SME to connect only to
- that AP.

- * Porting Notes:
- * Part of this file contains an example for how to glue the OS layer
- * with the HIP core lib, the SDIO glue layer, and the SME.
- *
- * When the unifi_sdio.ko modules loads, the linux kernel calls unifi_load().
- * unifi_load() calls uf_sdio_load() which is exported by the SDIO glue
- * layer. uf_sdio_load() registers this driver with the underlying SDIO driver.
- * When a card is detected, the SDIO glue layer calls register_unifi_sdio()
- * to pass the SDIO function context and ask the OS layer to initialise
- * the card. register_unifi_sdio() allocates all the private data of the OS
- * layer and calls uf_run_unifihelper() to start the SME. The SME calls
- * unifi_sys_wifi_on_req() which uses the HIP core lib to initialise the card.

- * When used with sdioemb, the udev scripts (at least on Ubuntu) don't
- * recognise a UniFi being added to the system. This is because sdioemb

- * to change this line:
- * SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
- * to these:
- * #SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
- * SUBSYSTEM=="net", GOTO="net_start"
- *
- * Then you can add a stanza to /etc/network/interfaces like this:
- * auto eth1
- * iface eth1 inet dhcp
- * wpa-conf /etc/wpa_supplicant.conf
- * This will then automatically associate when a car dis inserted.

- * and wireless extensions.
- * It is part of the porting exercise.

-/*
- * Porting Notes:
- * This file implements the data plane of the UniFi linux driver.
- *
- * All the Tx packets are passed to the HIP core lib, using the
- * unifi_send_signal() API. For EAPOL packets use the MLME-EAPOL.req
- * signal, for all other use the MLME-UNITDATA.req. The unifi_send_signal()
- * expects the wire-formatted (packed) signal. For convenience, in the OS
- * layer we only use the native (unpacked) signal structures. The HIP core lib
- * provides the write_pack() helper function to convert to the packed signal.
- * The packet is stored in the bulk data of the signal. We do not need to
- * allocate new memory to store the packet, because unifi_net_data_malloc()
- * is implemented to return a skb, which is the format of packet in Linux.
- * The HIP core lib frees the bulk data buffers, so we do not need to do
- * this in the OS layer.
- *
- * All the Rx packets are MLME-UNITDATA.ind signals, passed by the HIP core lib
- * in unifi_receive_event(). We do not need to allocate an skb and copy the
- * received packet because the HIP core lib has stored in memory allocated by
- * unifi_net_data_malloc(). Also, we can perform the 802.11 to Ethernet
- * translation in-place because we allocate the extra memory allocated in
- * unifi_net_data_malloc().
- *
- * If possible, the porting exercise should appropriately implement
- * unifi_net_data_malloc() and unifi_net_data_free() to save copies between
- * network and driver buffers.

- * This file also contains the implementation of the asynchronous
- * requests to the SME.
- *
- * Before calling an asynchronous SME function, we call sme_init_request()
- * which gets hold of the SME semaphore and updates the request status.
- * The semaphore makes sure that there is only one pending request to
- * the SME at a time.
- *
- * Now we are ready to call the SME function, but only if
- * sme_init_request() has returned 0.
- *
- * When the SME function returns, we need to wait
- * for the reply. This is done in sme_wait_for_reply().
- * If the request times-out, the request status is set to SME_REQUEST_TIMEDOUT
- * and the sme_wait_for_reply() returns.
- *
- * If the SME replies in time, we call sme_complete_request().
- * There we change the request status to SME_REQUEST_RECEIVED. This will
- * wake up the process waiting on sme_wait_for_reply().
- * It is important that we copy the reply data in priv->sme_reply
- * before calling sme_complete_request().
- *
- * Handling the wext requests, we need to block
- * until the SME sends the response to our request.
- * We use the sme_init_request() and sme_wait_for_reply()
- * to implement this behavior in the following functions:
- * sme_mgt_wifi_on()
- * sme_mgt_wifi_off()
- * sme_mgt_scan_full()

- * This function implements a blocking request-reply interface for WEXT.
- * To use it, a client specifies this function as the udi_event_callback
- * to ul_register_client(). The signal dispatcher in
- * unifi_receive_event() will call this function to deliver a signal.
- *
- * Arguments:
- * pcli Pointer to the client instance.
- * signal Pointer to the received signal.
- * signal_len Size of the signal structure in bytes.
- * bulkdata Pointer to structure containing any associated bulk data.
- * dir Direction of the signal. Zero means from host,
- * non-zero means to host.
- *
- * Returns:
- * None.

- * Claim/release SDIO
- *
- * For multifunction cards, we cannot grub the SDIO lock around the unifi_bh()
- * as this prevents other functions using SDIO.
- * Since some of CSR SDIO API is used regardless of trying to lock unifi_bh()
- * we have followed this scheme:
- * 1. If a function needs protection only when CSR_WIFI_SINGLE_FUNCTION is defined
- * then we call CsrSdioClaim/CsrSdioRelease().
- * 2. If a function needs protection only when CSR_WIFI_SINGLE_FUNCTION is not defined
- * then we call _sdio_claim_host/_sdio_claim_host(). Use of this should be restricted
- * to the SDIO glue layer only (e.g. sdio_mmc.c).
- * 3. If a function needs protection, regardless of the CSR_WIFI_SINGLE_FUNCTION
- * then we call directly the sdio_claim_host/sdio_release_host().
- * Use of this must be restricted to the SDIO glue layer only (e.g. sdio_mmc.c).
- *
- * Note: The _func and function pointers are _not_ the same.
- * The former is the (struct sdio_func*) context, which restricts the use to the SDIO glue layer.
- * The latter is the (CsrSdioFunction*) context, which allows calls from all layers.

+ * zbud.c
+ *
+ * Copyright (C) 2013, Seth Jennings, IBM
+ *
+ * Concepts based on zcache internal zbud allocator by Dan Magenheimer.
+ *
+ * zbud is an special purpose allocator for storing compressed pages. Contrary
+ * to what its name may suggest, zbud is not a buddy allocator, but rather an
+ * allocator that "buddies" two compressed pages together in a single memory
+ * page.
+ *
+ * While this design limits storage density, it has simple and deterministic
+ * reclaim properties that make it preferable to a higher density approach when
+ * reclaim will be used.
+ *
+ * zbud works by storing compressed pages, or "zpages", together in pairs in a
+ * single memory page called a "zbud page". The first buddy is "left
+ * justifed" at the beginning of the zbud page, and the last buddy is "right
+ * justified" at the end of the zbud page. The benefit is that if either
+ * buddy is freed, the freed buddy space, coalesced with whatever slack space
+ * that existed between the buddies, results in the largest possible free region
+ * within the zbud page.
+ *
+ * zbud also provides an attractive lower bound on density. The ratio of zpages
+ * to zbud pages can not be less than 1. This ensures that zbud can never "do
+ * harm" by using more pages to store zpages than the uncompressed zpages would
+ * have used on their own.
+ *
+ * zbud pages are divided into "chunks". The size of the chunks is fixed at
+ * compile time and determined by NCHUNKS_ORDER below. Dividing zbud pages
+ * into chunks allows organizing unbuddied zbud pages into a manageable number
+ * of unbuddied lists according to the number of free chunks available in the
+ * zbud page.
+ *
+ * The zbud API differs from that of conventional allocators in that the
+ * allocation function, zbud_alloc(), returns an opaque handle to the user,
+ * not a dereferenceable pointer. The user must map the handle using
+ * zbud_map() in order to get a usable pointer by which to access the
+ * allocation data and unmap the handle with zbud_unmap() when operations
+ * on the allocation data are complete.

- * If the weight and lmax (max_pkt_size) of the classes do not change,
- * then QFQ+ does meet the above contraint according to the current
- * values of its parameters. In fact, if the weight and lmax of the
- * classes do not change, then, from the theory, QFQ+ guarantees that
- * the slot index is never higher than
- * 2 + QFQ_MAX_AGG_CLASSES * ((1<<QFQ_MTU_SHIFT)/QFQ_MIN_LMAX) *
- * (QFQ_MAX_WEIGHT/QFQ_MAX_WSUM) = 2 + 8 * 128 * (1 / 64) = 18
+ * QFQ+ fully satisfies this bound to the slot index if the parameters
+ * of the classes are not changed dynamically, and if QFQ+ never
+ * happens to postpone the service of agg unjustly, i.e., it never
+ * happens that the aggregate becomes backlogged and eligible, or just
+ * eligible, while an aggregate with a higher approximated finish time
+ * is being served. In particular, in this case QFQ+ guarantees that
+ * the timestamps of agg are low enough that the slot index is never
+ * higher than 2. Unfortunately, QFQ+ cannot provide the same
+ * guarantee if it happens to unjustly postpone the service of agg, or
+ * if the parameters of some class are changed.
*
- * When the weight of a class is increased or the lmax of the class is
- * decreased, a new aggregate with smaller slot size than the original
- * parent aggregate of the class may happen to be activated. The
- * activation of this aggregate should be properly delayed to when the
- * service of the class has finished in the ideal system tracked by
- * QFQ+. If the activation of the aggregate is not delayed to this
- * reference time instant, then this aggregate may be unjustly served
- * before other aggregates waiting for service. This may cause the
- * above bound to the slot index to be violated for some of these
- * unlucky aggregates.
+ * As for the first event, i.e., an out-of-order service, the
+ * upper bound to the slot index guaranteed by QFQ+ grows to
+ * 2 +
+ * QFQ_MAX_AGG_CLASSES * ((1<<QFQ_MTU_SHIFT)/QFQ_MIN_LMAX) *
+ * (current_max_weight/current_wsum) <= 2 + 8 * 128 * 1.
+ *
+ * The following function deals with this problem by backward-shifting
+ * the timestamps of agg, if needed, so as to guarantee that the slot
+ * index is never higher than QFQ_MAX_SLOTS-2. This backward-shift may
+ * cause the service of other aggregates to be postponed, yet the
+ * worst-case guarantees of these aggregates are not violated. In
+ * fact, in case of no out-of-order service, the timestamps of agg
+ * would have been even lower than they are after the backward shift,
+ * because QFQ+ would have guaranteed a maximum value equal to 2 for
+ * the slot index, and 2 < QFQ_MAX_SLOTS-2. Hence the aggregates whose
+ * service is postponed because of the backward-shift would have
+ * however waited for the service of agg before being served.
+ *
+ * The other event that may cause the slot index to be higher than 2
+ * for agg is a recent change of the parameters of some class. If the
+ * weight of a class is increased or the lmax (max_pkt_size) of the
+ * class is decreased, then a new aggregate with smaller slot size
+ * than the original parent aggregate of the class may happen to be
+ * activated. The activation of this aggregate should be properly
+ * delayed to when the service of the class has finished in the ideal
+ * system tracked by QFQ+. If the activation of the aggregate is not
+ * delayed to this reference time instant, then this aggregate may be
+ * unjustly served before other aggregates waiting for service. This
+ * may cause the above bound to the slot index to be violated for some
+ * of these unlucky aggregates.
*
* Instead of delaying the activation of the new aggregate, which is
- * quite complex, the following inaccurate but simple solution is used:
- * if the slot index is higher than QFQ_MAX_SLOTS-2, then the
- * timestamps of the aggregate are shifted backward so as to let the
- * slot index become equal to QFQ_MAX_SLOTS-2.
+ * quite complex, the above-discussed capping of the slot index is
+ * used to handle also the consequences of a change of the parameters
+ * of a class.

its sibling is utilized.
Deepest package sleep states may in reality show up as machine/platform wide
sleep states and can only be entered if all cores are idle. Look up Intel
manuals (some are provided in the References section) for further details.
+The monitors are named after the CPU family where the sleep state capabilities
+got introduced and may not match exactly the CPU name of the platform.
