Glossary + + + 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 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. + + + Glossary + +*DWA* -- Device Wire Adapter + +USB host, wired for downstream devices, upstream connects wirelessly +with Wireless USB. + +*EVENT* -- Response to a command on the NEEP + +*HWA* -- Host Wire Adapter / USB dongle for UWB and Wireless USB + +*NEH* -- Notification/Event Handle + +Handle/file descriptor for receiving notifications or events.

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. diff --git a/Documentation/usb/wusb-cbaf b/Documentation/usb/wusb-cbaf new file mode 100644 index 000000000000..a385478ba12e --- /dev/null +++ b/Documentation/usb/wusb-cbaf @@ -0,0 +1,133 @@ +#! /bin/bash +# + +set -e + +progname=$(basename $0) +function help +{ + cat <<EOF +Usage: $progname COMMAND DEVICEs [ARGS] + +Command for manipulating the pairing/authentication credentials of a +Wireless USB device that supports wired-mode Cable-Based-Association. + +Works in conjunction with the wusb-cba.ko driver from http://linuxuwb.org. + + +DEVICE + + sysfs path to the device to authenticate; for example, both this + guys are the same: + + /sys/devices/pci0000:00/0000:00:1d.7/usb1/1-4/1-4.4/1-4.4:1.1 + /sys/bus/usb/drivers/wusb-cbaf/1-4.4:1.1 + +COMMAND/ARGS are + + start + + Start a WUSB host controller (by setting up a CHID) + + set-chid DEVICE HOST-CHID HOST-BANDGROUP HOST-NAME + + Sets host information in the device; after this you can call the + get-cdid to see how does this device report itself to us. + + get-cdid DEVICE + + Get the device ID associated to the HOST-CHDI we sent with + 'set-chid'.

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).

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.
