+ * old userspace intel graphics drivers needed an interface to map memory into
+ * the GTT. And the drm provides a default interface for graphic devices sitting
+ * on an agp port. So it made sense to fake the GTT support as an agp port to
+ * avoid having to create a new api.
+ *
+ * With gem this does not make much sense anymore, just needlessly complicates
+ * the code. But as long as the old graphics stack is still support, it's stuck
+ * here.

+/*
+ * Software methods, why they are needed, and how they all work:
+ *
+ * NV04 and NV05 keep most of the state in PGRAPH context itself, but some
+ * 2d engine settings are kept inside the grobjs themselves. The grobjs are
+ * 3 words long on both. grobj format on NV04 is:
+ *
+ * word 0:
+ * - bits 0-7: class
+ * - bit 12: color key active
+ * - bit 13: clip rect active
+ * - bit 14: if set, destination surface is swizzled and taken from buffer 5
+ * [set by NV04_SWIZZLED_SURFACE], otherwise it's linear and taken
+ * from buffer 0 [set by NV04_CONTEXT_SURFACES_2D or
+ * NV03_CONTEXT_SURFACE_DST].
+ * - bits 15-17: 2d operation [aka patch config]
+ * - bit 24: patch valid [enables rendering using this object]
+ * - bit 25: surf3d valid [for tex_tri and multitex_tri only]
+ * word 1:
+ * - bits 0-1: mono format
+ * - bits 8-13: color format
+ * - bits 16-31: DMA_NOTIFY instance
+ * word 2:
+ * - bits 0-15: DMA_A instance
+ * - bits 16-31: DMA_B instance
+ *
+ * On NV05 it's:
+ *
+ * word 0:
+ * - bits 0-7: class
+ * - bit 12: color key active
+ * - bit 13: clip rect active
+ * - bit 14: if set, destination surface is swizzled and taken from buffer 5
+ * [set by NV04_SWIZZLED_SURFACE], otherwise it's linear and taken
+ * from buffer 0 [set by NV04_CONTEXT_SURFACES_2D or
+ * NV03_CONTEXT_SURFACE_DST].
+ * - bits 15-17: 2d operation [aka patch config]
+ * - bits 20-22: dither mode
+ * - bit 24: patch valid [enables rendering using this object]
+ * - bit 25: surface_dst/surface_color/surf2d/surf3d valid
+ * - bit 26: surface_src/surface_zeta valid
+ * - bit 27: pattern valid
+ * - bit 28: rop valid
+ * - bit 29: beta1 valid
+ * - bit 30: beta4 valid
+ * word 1:
+ * - bits 0-1: mono format
+ * - bits 8-13: color format
+ * - bits 16-31: DMA_NOTIFY instance
+ * word 2:
+ * - bits 0-15: DMA_A instance
+ * - bits 16-31: DMA_B instance
+ *
+ * NV05 will set/unset the relevant valid bits when you poke the relevant
+ * object-binding methods with object of the proper type, or with the NULL
+ * type. It'll only allow rendering using the grobj if all needed objects
+ * are bound. The needed set of objects depends on selected operation: for
+ * example rop object is needed by ROP_AND, but not by SRCCOPY_AND.
+ *
+ * NV04 doesn't have these methods implemented at all, and doesn't have the
+ * relevant bits in grobj. Instead, it'll allow rendering whenever bit 24
+ * is set. So we have to emulate them in software, internally keeping the
+ * same bits as NV05 does. Since grobjs are aligned to 16 bytes on nv04,
+ * but the last word isn't actually used for anything, we abuse it for this
+ * purpose.
+ *
+ * Actually, NV05 can optionally check bit 24 too, but we disable this since
+ * there's no use for it.
+ *
+ * For unknown reasons, NV04 implements surf3d binding in hardware as an
+ * exception. Also for unknown reasons, NV04 doesn't implement the clipping
+ * methods on the surf3d object, so we have to emulate them too.

+ * A virtual v4l2-mem2mem example device.
+ *
+ * This is a virtual device driver for testing mem-to-mem videobuf framework.
+ * It simulates a device that uses memory buffers for both source and
+ * destination, processes the data and issues an "irq" (simulated by a timer).
+ * The device is capable of multi-instance, multi-buffer-per-transaction
+ * operation (via the mem2mem framework).

+ This is VMware physical memory management driver which acts

- max6875.c - driver for MAX6874/MAX6875
-
- Copyright (C) 2005 Ben Gardner <bgardner@wabtec.com>
-
- Based on eeprom.c
-
- The MAX6875 has a bank of registers and two banks of EEPROM.
- Address ranges are defined as follows:
- * 0x0000 - 0x0046 = configuration registers
- * 0x8000 - 0x8046 = configuration EEPROM
- * 0x8100 - 0x82FF = user EEPROM
-
- This driver makes the user EEPROM available for read.
-
- The registers & config EEPROM should be accessed via i2c-dev.
-
- The MAX6875 ignores the lowest address bit, so each chip responds to
- two addresses - 0x50/0x51 and 0x52/0x53.
-
- Note that the MAX6875 uses i2c_smbus_write_byte_data() to set the read
- address, so this driver is destructive if loaded for the wrong EEPROM chip.
-
- This program is free software; you can redistribute it and/or modify

-/* This driver handles only L2TP data frames; control frames are handled by a
- * userspace application.
- *
- * To send data in an L2TP session, userspace opens a PPPoL2TP socket and
- * attaches it to a bound UDP socket with local tunnel_id / session_id and
- * peer tunnel_id / session_id set. Data can then be sent or received using
- * regular socket sendmsg() / recvmsg() calls. Kernel parameters of the socket
- * can be read or modified using ioctl() or [gs]etsockopt() calls.
- *
- * When a PPPoL2TP socket is connected with local and peer session_id values
- * zero, the socket is treated as a special tunnel management socket.
- *
- * Here's example userspace code to create a socket for sending/receiving data
- * over an L2TP session:-
- *
- * struct sockaddr_pppol2tp sax;
- * int fd;
- * int session_fd;
- *
- * fd = socket(AF_PPPOX, SOCK_DGRAM, PX_PROTO_OL2TP);
- *
- * sax.sa_family = AF_PPPOX;
- * sax.sa_protocol = PX_PROTO_OL2TP;
- * sax.pppol2tp.fd = tunnel_fd; // bound UDP socket
- * sax.pppol2tp.addr.sin_addr.s_addr = addr->sin_addr.s_addr;
- * sax.pppol2tp.addr.sin_port = addr->sin_port;
- * sax.pppol2tp.addr.sin_family = AF_INET;
- * sax.pppol2tp.s_tunnel = tunnel_id;
- * sax.pppol2tp.s_session = session_id;
- * sax.pppol2tp.d_tunnel = peer_tunnel_id;
- * sax.pppol2tp.d_session = peer_session_id;
- *
- * session_fd = connect(fd, (struct sockaddr *)&sax, sizeof(sax));
- *
- * A pppd plugin that allows PPP traffic to be carried over L2TP using
- * this driver is available from the OpenL2TP project at
- * http://openl2tp.sourceforge.net.

+ * Adaptive Noise Immunity (ANI) controls five noise immunity parameters
+ * depending on the amount of interference in the environment, increasing

+ *
+ * The parameters are:
+ * - "noise immunity"
+ * - "spur immunity"
+ * - "firstep level"
+ * - "OFDM weak signal detection"
+ * - "CCK weak signal detection"
+ *
+ * Basically we look at the amount of ODFM and CCK timing errors we get and then
+ * raise or lower immunity accordingly by setting one or more of these
+ * parameters.
+ * Newer chipsets have PHY error counters in hardware which will generate a MIB
+ * interrupt when they overflow. Older hardware has too enable PHY error frames
+ * by setting a RX flag and then count every single PHY error. When a specified
+ * threshold of errors has been reached we will raise immunity.
+ * Also we regularly check the amount of errors and lower or raise immunity as
+ * necessary.

- tristate "Aironet Arlan 655 & IC2200 DS support"
- depends on ISA && !64BIT && WLAN
- select WIRELESS_EXT
- ---help---
- Aironet makes Arlan, a class of wireless LAN adapters. These use the
- www.Telxon.com chip, which is also used on several similar cards.
- This driver is tested on the 655 and IC2200 series cards. Look at
- <http://www.ylenurme.ee/~elmer/655/> for the latest information.
-
- The driver is built as two modules, arlan and arlan-proc. The latter
- is the /proc interface and is not needed most of time.
-
- On some computers the card ends up in non-valid state after some
- time. Use a ping-reset script to clear it.

BATMAN-ADV
----------
-Batman-advanced is a new approach to wireless networking which does no longer
-operate on the IP basis. Unlike B.A.T.M.A.N, which exchanges information
-using UDP packets and sets routing tables, batman-advanced operates on ISO/OSI
-Layer 2 only and uses and routes (or better: bridges) Ethernet Frames. It
-emulates a virtual network switch of all nodes participating. Therefore all
-nodes appear to be link local, thus all higher operating protocols won't be
-affected by any changes within the network. You can run almost any protocol
-above B.A.T.M.A.N. Advanced, prominent examples are: IPv4, IPv6, DHCP, IPX.

-USAGE
------
+CONFIGURATION
+-------------
-insmod the batman-adv.ko in your kernel:
+Load the batman-adv module into your kernel:
# insmod batman-adv.ko
-the module is now waiting for activation. You must add some interfaces
-on which batman can operate. Each interface must be added separately:
+The module is now waiting for activation. You must add some in-
+terfaces on which batman can operate. After loading the module
+batman advanced will scan your systems interfaces to search for
+compatible interfaces. Once found, it will create subfolders in
+the /sys directories of each supported interface, e.g.
+
+# ls /sys/class/net/eth0/batman_adv/
+# iface_status mesh_iface
+
+If an interface does not have the "batman_adv" subfolder it prob-
+ably is not supported. Not supported interfaces are: loopback,
+non-ethernet and batman's own interfaces.
+
+Note: After the module was loaded it will continuously watch for
+new interfaces to verify the compatibility. There is no need to
+reload the module if you plug your USB wifi adapter into your ma-
+chine after batman advanced was initially loaded.
+
+To activate a given interface simply write "bat0" into its
+"mesh_iface" file inside the batman_adv subfolder:
+
+# echo bat0 > /sys/class/net/eth0/batman_adv/mesh_iface
+
+Repeat this step for all interfaces you wish to add. Now batman
+starts using/broadcasting on this/these interface(s).
-# echo wlan0 > /proc/net/batman-adv/interfaces
+By reading the "iface_status" file you can check its status:
-( # echo wlan1 > /proc/net/batman-adv/interfaces )
-( # echo eth0 > /proc/net/batman-adv/interfaces )
-( ... )
+# cat /sys/class/net/eth0/batman_adv/iface_status
+# active
-Now batman starts broadcasting on this interface.
-You can now view the table of originators (mesh participants) with:
+To deactivate an interface you have to write "none" into its
+"mesh_iface" file:
-# cat /proc/net/batman-adv/originators
+# echo none > /sys/class/net/eth0/batman_adv/mesh_iface
-The module will create a new interface "bat0", which can be used as a
-regular interface:
-# ifconfig bat0 inet 192.168.0.1 up
-# ping 192.168.0.2
-...
+All mesh wide settings can be found in batman's own interface
+folder:
-If you want topology visualization, your meshnode must be configured
-as VIS-server:
+# ls /sys/class/net/bat0/mesh/
+# aggregate_ogm originators transtable_global vis_mode
+# orig_interval transtable_local vis_data
-# echo "server" > /proc/net/batman-adv/vis
-Each node is either configured as "server" or as "client" (default:
-"client"). Clients send their topology data to the server next to them,
-and server synchronize with other servers. If there is no server
-configured (default) within the mesh, no topology information will be
-transmitted. With these "synchronizing servers", there can be 1 or
-more vis servers sharing the same (or at least very similar) data.
+Some of the files contain all sort of status information regard-
+ing the mesh network. For example, you can view the table of
+originators (mesh participants) with:
-When configured as server, you can get a topology snapshot of your mesh:
+# cat /sys/class/net/bat0/mesh/originators
-# cat /proc/net/batman-adv/vis
+Other files allow to change batman's behaviour to better fit your
+requirements. For instance, you can check the current originator
+interval (value in milliseconds which determines how often batman
+sends its broadcast packets):
-The output is in a generic raw format. Use the batctl tool (See below)
-to convert this to other formats more suitable for graphing, eg
-graphviz dot, or JSON data-interchange format.
+# cat /sys/class/net/bat0/mesh/orig_interval
+# status: 1000
+
+and also change its value:
+
+# echo 3000 > /sys/class/net/bat0/mesh/orig_interval
In very mobile scenarios, you might want to adjust the originator
-interval to a lower value. This will make the mesh more responsive to
-topology changes, but will also increase the overhead. Please make sure
-that all nodes in your mesh use the same interval. The default value
-is 1000 ms (1 second).
+interval to a lower value. This will make the mesh more respon-
+sive to topology changes, but will also increase the overhead.
+
+
+USAGE
+-----
+
+To make use of your newly created mesh, batman advanced provides
+a new interface "bat0" which you should use from this point on.
+All interfaces added to batman advanced are not relevant any
+longer because batman handles them for you. Basically, one "hands
+over" the data by using the batman interface and batman will make
+sure it reaches its destination.
-# echo 1000 > /proc/net/batman-adv/orig_interval
+The "bat0" interface can be used like any other regular inter-
+face. It needs an IP address which can be either statically con-
+figured or dynamically (by using DHCP or similar services):
-To deactivate batman, do:
+# NodeA: ifconfig bat0 192.168.0.1
+# NodeB: ifconfig bat0 192.168.0.2
+# NodeB: ping 192.168.0.1
+
+Note: In order to avoid problems remove all IP addresses previ-
+ously assigned to interfaces now used by batman advanced, e.g.
+
+# ifconfig eth0 0.0.0.0
+
+
+VISUALIZATION
+-------------
+
+If you want topology visualization, at least one mesh node must
+be configured as VIS-server:
+
+# echo "server" > /sys/class/net/bat0/mesh/vis_mode
+
+Each node is either configured as "server" or as "client" (de-
+fault: "client"). Clients send their topology data to the server
+next to them, and server synchronize with other servers. If there
+is no server configured (default) within the mesh, no topology
+information will be transmitted. With these "synchronizing
+servers", there can be 1 or more vis servers sharing the same (or
+at least very similar) data.
+
+When configured as server, you can get a topology snapshot of
+your mesh:
+
+# cat /sys/class/net/bat0/mesh/vis_data
+
+This raw output is intended to be easily parsable and convertable
+with other tools. Have a look at the batctl README if you want a
+vis output in dot or json format for instance and how those out-
+puts could then be visualised in an image.
+
+The raw format consists of comma separated values per entry where
+each entry is giving information about a certain source inter-
+face. Each entry can/has to have the following values:
+-> "mac" - mac address of an originator's source interface
+ (each line begins with it)
+-> "TQ mac value" - src mac's link quality towards mac address
+ of a neighbor originator's interface which
+ is being used for routing
+-> "HNA mac" - HNA announced by source mac
+-> "PRIMARY" - this is a primary interface
+-> "SEC mac" - secondary mac address of source
+ (requires preceding PRIMARY)
+
+The TQ value has a range from 4 to 255 with 255 being the best.
+The HNA entries are showing which hosts are connected to the mesh
+via bat0 or being bridged into the mesh network. The PRIMARY/SEC
+values are only applied on primary interfaces
-# echo "" > /proc/net/batman-adv/interfaces

+ * How to be a proc read function

+ *
+ * Assume that the buffer is "count" bytes in size.
+ *
+ * If you know you have supplied all the data you
+ * have, set *peof.
+ *
+ * You have three ways to return data:
+ * 0) Leave *start = NULL. (This is the default.)
+ * Put the data of the requested offset at that
+ * offset within the buffer. Return the number (n)
+ * of bytes there are from the beginning of the
+ * buffer up to the last byte of data. If the
+ * number of supplied bytes (= n - offset) is
+ * greater than zero and you didn't signal eof
+ * and the reader is prepared to take more data
+ * you will be called again with the requested
+ * offset advanced by the number of bytes
+ * absorbed. This interface is useful for files
+ * no larger than the buffer.
+ * 1) Set *start = an unsigned long value less than
+ * the buffer address but greater than zero.
+ * Put the data of the requested offset at the
+ * beginning of the buffer. Return the number of
+ * bytes of data placed there. If this number is
+ * greater than zero and you didn't signal eof
+ * and the reader is prepared to take more data
+ * you will be called again with the requested
+ * offset advanced by *start. This interface is
+ * useful when you have a large file consisting
+ * of a series of blocks which you want to count
+ * and return as wholes.
+ * (Hack by Paul.Russell@rustcorp.com.au)
+ * 2) Set *start = an address within the buffer.
+ * Put the data of the requested offset at *start.
+ * Return the number of bytes of data placed there.
+ * If this number is greater than zero and you
+ * didn't signal eof and the reader is prepared to
+ * take more data you will be called again with the
+ * requested offset advanced by the number of bytes

+Description:
+ Some devices have internal clocks. This parameter sets the

+Contact: linux-iio@vger.kernel.org
+Description:
+ Event generated when accel_x0 passes a threshold in correction direction
+ (or stays beyond one). If direction isn't specified, either triggers it.
+ Note driver will assume last p events requested are enabled where p is
+ however many it supports. So if you want to be sure you have
+ set what you think you have, check the contents of these. Drivers
+ may have to buffer any parameters so that they are consistent when a
+ given event type is enabled a future point (and not those for whatever
+ alarm was previously enabled).

+ depends on RAR_REGISTER
+ ---help---
+ This driver provides a memory management interface to
+ restricted access regions (RAR) available on the Intel
+ Moorestown platform.
+
+ Once locked down, restricted access regions are only
+ accessible by specific hardware on the platform. The x86
+ CPU is typically not one of those platforms. As such this
+ driver does not access RAR, and only provides a buffer
+ allocation/bookkeeping mechanism.
+
+ If unsure, say N.

+RAR Handler (memrar) Driver TODO Items
+======================================
+
+Maintainer: Ossama Othman <ossama.othman@intel.com>
+
+memrar.h
+--------
+1. This header exposes the driver's user space and kernel space
+ interfaces. It should be moved to <linux/rar/memrar.h>, or
+ something along those lines, when this memrar driver is moved out
+ of `staging'.
+ a. It would be ideal if staging/rar_register/rar_register.h was
+ moved to the same directory.
+
+memrar_allocator.[ch]
+---------------------
+1. Address potential fragmentation issues with the memrar_allocator.
+
+2. Hide struct memrar_allocator details/fields. They need not be
+ exposed to the user.
+ a. Forward declare struct memrar_allocator.
+ b. Move all three struct definitions to `memrar_allocator.c'
+ source file.
+ c. Add a memrar_allocator_largest_free_area() function, or
+ something like that to get access to the value of the struct
+ memrar_allocator "largest_free_area" field. This allows the
+ struct memrar_allocator fields to be completely hidden from
+ the user. The memrar_handler code really only needs this for
+ statistic gathering on-demand.
+ d. Do the same for the "capacity" field as the
+ "largest_free_area" field.
+
+3. Move memrar_allocator.* to kernel `lib' directory since it is HW
+ neutral.
+ a. Alternatively, use lib/genalloc.c instead.
+ b. A kernel port of Doug Lea's malloc() implementation may also
+ be an option.
+
+memrar_handler.c
+----------------
+1. Split user space interface (ioctl code) from core/kernel code,
+ e.g.:
+ memrar_handler.c -> memrar_core.c, memrar_user.c

+Description: The Intel Moorestown Restricted Access Region (RAR)
+ Handler driver exposes an ioctl() based interface that
+ allows a user to reserve and release blocks of RAR
+ memory.
+
+ Note: A sysfs based one was not appropriate for the
+ RAR handler's usage model.
+
+ =========================================================
+ ioctl() Requests
+ =========================================================
+ RAR_HANDLER_RESERVE
+ -------------------
+ Description: Reserve RAR block.
+ Type: struct RAR_block_info
+ Direction: in/out
+ Errors: EINVAL (invalid RAR type or size)
+ ENOMEM (not enough RAR memory)
+
+ RAR_HANDLER_STAT
+ ----------------
+ Description: Get RAR statistics.
+ Type: struct RAR_stat
+ Direction: in/out
+ Errors: EINVAL (invalid RAR type)
+
+ RAR_HANDLER_RELEASE
+ -------------------
+ Description: Release previously reserved RAR block.
+ Type: 32 bit unsigned integer
+ (e.g. uint32_t), i.e the RAR "handle".
+ Direction: in
+ Errors: EINVAL (invalid RAR handle)
+
+
+ =========================================================
+ ioctl() Request Parameter Types
+ =========================================================
+ The structures referred to above are defined as
+ follows:
+
+ /**
+ * struct RAR_block_info - user space struct that
+ * describes RAR buffer
+ * @type: Type of RAR memory (e.g.,
+ * RAR_TYPE_VIDEO or RAR_TYPE_AUDIO) [in]
+ * @size: Requested size of a block in bytes to
+ * be reserved in RAR. [in]
+ * @handle: Handle that can be used to refer to
+ * reserved block. [out]
+ *
+ * This is the basic structure exposed to the user
+ * space that describes a given RAR buffer. It used
+ * as the parameter for the RAR_HANDLER_RESERVE ioctl.
+ * The buffer's underlying bus address is not exposed
+ * to the user. User space code refers to the buffer
+ * entirely by "handle".
+ */
+ struct RAR_block_info {
+ __u32 type;
+ __u32 size;
+ __u32 handle;
+ };
+
+ /**
+ * struct RAR_stat - RAR statistics structure
+ * @type: Type of RAR memory (e.g.,
+ * RAR_TYPE_VIDEO or
+ * RAR_TYPE_AUDIO) [in]
+ * @capacity: Total size of RAR memory
+ * region. [out]
+ * @largest_block_size: Size of the largest reservable
+ * block. [out]
+ *
+ * This structure is used for RAR_HANDLER_STAT ioctl.
+ */
+ struct RAR_stat {
+ __u32 type;
+ __u32 capacity;
+ __u32 largest_block_size;
+ };
+
+ Lastly, the RAR_HANDLER_RELEASE ioctl expects a
+ "handle" to the RAR block of memory. It is a 32 bit
+ unsigned integer.

- *
- * Filename: netwave_cs.c
- * Version: 0.4.1
- * Description: Netwave AirSurfer Wireless LAN PC Card driver
- * Status: Experimental.
- * Authors: John Markus Bjørndalen <johnm@cs.uit.no>
- * Dag Brattli <dagb@cs.uit.no>
- * David Hinds <dahinds@users.sourceforge.net>
- * Created at: A long time ago!
- * Modified at: Mon Nov 10 11:54:37 1997
- * Modified by: Dag Brattli <dagb@cs.uit.no>
- *
- * Copyright (c) 1997 University of Tromsø, Norway
- *
- * Revision History:
- *
- * 08-Nov-97 15:14:47 John Markus Bjørndalen <johnm@cs.uit.no>
- * - Fixed some bugs in netwave_rx and cleaned it up a bit.
- * (One of the bugs would have destroyed packets when receiving
- * multiple packets per interrupt).
- * - Cleaned up parts of newave_hw_xmit.
- * - A few general cleanups.
- * 24-Oct-97 13:17:36 Dag Brattli <dagb@cs.uit.no>
- * - Fixed netwave_rx receive function (got updated docs)
- * Others:
- * - Changed name from xircnw to netwave, take a look at
- * http://www.netwave-wireless.com
- * - Some reorganizing of the code
- * - Removed possible race condition between interrupt handler and transmit
- * function
- * - Started to add wireless extensions, but still needs some coding
- * - Added watchdog for better handling of transmission timeouts
- * (hopefully this works better)

-TODO:
- - Rx block size is limited to < 2048, hardware bug?
- - Group size is limited to < page size, kernel alloc/mmap API issues
- - test whether Tx is transmitting data from provided buffers
- - handle device unplug case
- - handle temperature above threshold
- - use bus address instead of physical address for DMA
- - support for snapshot mode
- - audit userspace interfaces
- - get reserved major/minor if needed

- Say Y if you have a Metricom radio and intend to use Starmode Radio
- IP. STRIP is a radio protocol developed for the MosquitoNet project
- to send Internet traffic using Metricom radios. Metricom radios are
- small, battery powered, 100kbit/sec packet radio transceivers, about
- the size and weight of a cellular telephone. (You may also have heard
- them called "Metricom modems" but we avoid the term "modem" because
- it misleads many people into thinking that you can plug a Metricom
- modem into a phone line and use it as a modem.)
-
- You can use STRIP on any Linux machine with a serial port, although
- it is obviously most useful for people with laptop computers. If you
- think you might get a Metricom radio in the future, there is no harm
- in saying Y to STRIP now, except that it makes the kernel a bit
- bigger.
-
- To compile this as a module, choose M here: the module will be
- called strip.

- * Note: manual_dev_addr hack
- *
- * It is not possible to change the hardware address of a Metricom radio,
- * or to send packets with a user-specified hardware source address, thus
- * trying to manually set a hardware source address is a questionable
- * thing to do. However, if the user *does* manually set the hardware
- * source address of a STRIP interface, then the kernel will believe it,
- * and use it in certain places. For example, the hardware address listed
- * by ifconfig will be the manual address, not the true one.
- * (Both addresses are listed in /proc/net/strip.)
- * Also, ARP packets will be sent out giving the user-specified address as
- * the source address, not the real address. This is dangerous, because
- * it means you won't receive any replies -- the ARP replies will go to
- * the specified address, which will be some other radio. The case where
- * this is useful is when that other radio is also connected to the same
- * machine. This allows you to connect a pair of radios to one machine,
- * and to use one exclusively for inbound traffic, and the other
- * exclusively for outbound traffic. Pretty neat, huh?
- *
- * Here's the full procedure to set this up:
- *
- * 1. "slattach" two interfaces, e.g. st0 for outgoing packets,
- * and st1 for incoming packets
- *
- * 2. "ifconfig" st0 (outbound radio) to have the hardware address
- * which is the real hardware address of st1 (inbound radio).
- * Now when it sends out packets, it will masquerade as st1, and
- * replies will be sent to that radio, which is exactly what we want.
- *
- * 3. Set the route table entry ("route add default ..." or
- * "route add -net ...", as appropriate) to send packets via the st0
- * interface (outbound radio). Do not add any route which sends packets
- * out via the st1 interface -- that radio is for inbound traffic only.
- *
- * 4. "ifconfig" st1 (inbound radio) to have hardware address zero.
- * This tells the STRIP driver to "shut down" that interface and not
- * send any packets through it. In particular, it stops sending the
- * periodic gratuitous ARP packets that a STRIP interface normally sends.
- * Also, when packets arrive on that interface, it will search the
- * interface list to see if there is another interface who's manual
- * hardware address matches its own real address (i.e. st0 in this
- * example) and if so it will transfer ownership of the skbuff to
- * that interface, so that it looks to the kernel as if the packet
- * arrived on that interface. This is necessary because when the
- * kernel sends an ARP packet on st0, it expects to get a reply on
- * st0, and if it sees the reply come from st1 then it will ignore
- * it (to be accurate, it puts the entry in the ARP table, but
- * labelled in such a way that st0 can't use it).
- *
- * Thanks to Petros Maniatis for coming up with the idea of splitting
- * inbound and outbound traffic between two interfaces, which turned
- * out to be really easy to implement, even if it is a bit of a hack.
- *
- * Having set a manual address on an interface, you can restore it
- * to automatic operation (where the address is automatically kept
- * consistent with the real address of the radio) by setting a manual
- * address of all ones, e.g. "ifconfig st0 hw strip FFFFFFFFFFFF"
- * This 'turns off' manual override mode for the device address.
- *
- * Note: The IEEE 802 headers reported in tcpdump will show the *real*
- * radio addresses the packets were sent and received from, so that you
- * can see what is really going on with packets, and which interfaces
- * they are really going through.

+TODO:
+
+1. A per-device/tty port context required to support multiple devices
+on same platform.
+
+2. REMOVE the sysfs entry PID passing mechanism, since there should
+be a better way to request user-space to install line discipline.
+
+3. Re-view/Re-work on the locking.
+
+4. Re-structure to make the ldisc driver more generic for chipsets which mux
+multiple connectivity (BT, FM, GPS) upon 1 TTY port.
+
+5. Step up and maintain this driver to ensure that it continues
+to work. Having the hardware for this is pretty much a
+requirement. If this does not happen, the will be removed in
+the 2.6.35 kernel release.
+
+Please send patches to Greg Kroah-Hartman <greg@kroah.com>.

+Todo:
+ - Fix the loss of some blocks when receiving the video URB's
+ - Add a lock at tm6000_read_write_usb() to prevent two simultaneous access to the
+ URB control transfers
+ - Properly add the locks at tm6000-video
+ - Add audio support
+ - Add vbi support
+ - Add IR support
+ - Do several cleanups
+ - I think that frame1/frame0 are inverted. This causes a funny effect at the image.
+ the fix is trivial, but require some tests
+ - My tm6010 devices sometimes insist on stop working. I need to turn them off, removing
+ from my machine and wait for a while for it to work again. I'm starting to think that
+ it is an overheat issue - is there a workaround that we could do?
+ - Sometimes, tm6010 doesn't read eeprom at the proper time (hardware bug). So, the device
+ got miss-detected as a "generic" tm6000. This can be really bad if the tuner is the
+ Low Power one, as it may result on loading the high power firmware, that could damage
+ the device. Maybe we may read eeprom to double check, when the device is marked as "generic"
+ - Coding Style fixes
+ - sparse cleanups
+
+Please send patches to linux-media@vger.kernel.org

- The Lucent WaveLAN (formerly NCR and AT&T; or DEC RoamAbout DS) is
- a Radio LAN (wireless Ethernet-like Local Area Network) using the
- radio frequencies 900 MHz and 2.4 GHz.
-
- If you want to use an ISA WaveLAN card under Linux, say Y and read
- the Ethernet-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>. Some more specific
- information is contained in
- <file:Documentation/networking/wavelan.txt> and in the source code
- <file:drivers/net/wireless/wavelan.p.h>.
-
- You will also need the wireless tools package available from
- <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
- Please read the man pages contained therein.
-
- To compile this driver as a module, choose M here: the module will be
- called wavelan.

-/*
- * This driver provides a Linux interface to the WaveLAN ISA hardware.
- * The WaveLAN is a product of Lucent (http://www.wavelan.com/).
- * This division was formerly part of NCR and then AT&T.
- * WaveLANs are also distributed by DEC (RoamAbout DS) and Digital Ocean.
- *
- * To learn how to use this driver, read the NET3 HOWTO.
- * If you want to exploit the many other functionalities, read the comments
- * in the code.
- *
- * This driver is the result of the effort of many people (see below).
- */
-
-/* ------------------------ SPECIFIC NOTES ------------------------ */
-/*
- * Web page
- * --------
- * I try to maintain a web page with the Wireless LAN Howto at :
- * http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
- *
- * SMP
- * ---
- * We now are SMP compliant (I eventually fixed the remaining bugs).
- * The driver has been tested on a dual P6-150 and survived my usual
- * set of torture tests.
- * Anyway, I spent enough time chasing interrupt re-entrancy during
- * errors or reconfigure, and I designed the locked/unlocked sections
- * of the driver with great care, and with the recent addition of
- * the spinlock (thanks to the new API), we should be quite close to
- * the truth.
- * The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
- * but better safe than sorry (especially at 2 Mb/s ;-).
- *
- * I have also looked into disabling only our interrupt on the card
- * (via HACR) instead of all interrupts in the processor (via cli),
- * so that other driver are not impacted, and it look like it's
- * possible, but it's very tricky to do right (full of races). As
- * the gain would be mostly for SMP systems, it can wait...
- *
- * Debugging and options
- * ---------------------
- * You will find below a set of '#define" allowing a very fine control
- * on the driver behaviour and the debug messages printed.
- * The main options are :
- * o SET_PSA_CRC, to have your card correctly recognised by
- * an access point and the Point-to-Point diagnostic tool.
- * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
- * (otherwise we always start afresh with some defaults)
- *
- * wavelan.o is too darned big
- * ---------------------------
- * That's true! There is a very simple way to reduce the driver
- * object by 33%! Comment out the following line:
- * #include <linux/wireless.h>
- * Other compile options can also reduce the size of it...
- *
- * MAC address and hardware detection:
- * -----------------------------------
- * The detection code for the WaveLAN checks that the first three
- * octets of the MAC address fit the company code. This type of
- * detection works well for AT&T cards (because the AT&T code is
- * hardcoded in wavelan.h), but of course will fail for other
- * manufacturers.
- *
- * If you are sure that your card is derived from the WaveLAN,
- * here is the way to configure it:
- * 1) Get your MAC address
- * a) With your card utilities (wfreqsel, instconf, etc.)
- * b) With the driver:
- * o compile the kernel with DEBUG_CONFIG_INFO enabled
- * o Boot and look the card messages
- * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
- * 3) Compile and verify
- * 4) Send me the MAC code. I will include it in the next version.
- *

-
-/* --------------------- WIRELESS EXTENSIONS --------------------- */
-/*
- * This driver is the first to support "wireless extensions".
- * This set of extensions provides a standard way to control the wireless
- * characteristics of the hardware. Applications such as mobile IP may
- * take advantage of it.
- *
- * It might be a good idea as well to fetch the wireless tools to
- * configure the device and play a bit.

-/* --------------------------- HISTORY --------------------------- */
-/*
- * This is based on information in the drivers' headers. It may not be
- * accurate, and I guarantee only my best effort.
- *
- * The history of the WaveLAN drivers is as complicated as the history of
- * the WaveLAN itself (NCR -> AT&T -> Lucent).
- *
- * It all started with Anders Klemets <klemets@paul.rutgers.edu>
- * writing a WaveLAN ISA driver for the Mach microkernel. Girish
- * Welling <welling@paul.rutgers.edu> had also worked on it.
- * Keith Moore modified this for the PCMCIA hardware.
- *
- * Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI
- * and added specific PCMCIA support (there is currently no equivalent
- * of the PCMCIA package under BSD).
- *
- * Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD.
- *
- * Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux.
- *
- * Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver
- * (with help of the BSDI PCMCIA driver) for PCMCIA.
- * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work.
- * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
- * 2.00 cards correctly (2.4 GHz with frequency selection).
- * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
- * PCMCIA package (and bug corrections).
- *
- * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
- * patches to the PCMCIA driver. Later, I added code in the ISA driver
- * for Wireless Extensions and full support of frequency selection
- * cards. Then, I did the same to the PCMCIA driver, and did some
- * reorganisation. Finally, I came back to the ISA driver to
- * upgrade it at the same level as the PCMCIA one and reorganise
- * the code.
- * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
- * much needed information on the WaveLAN hardware.

-/* ------------------------- IMPROVEMENTS ------------------------- */
-/*
- * I proudly present:
- *
- * Changes made in first pre-release:
- * ----------------------------------
- * - reorganisation of the code, function name change
- * - creation of private header (wavelan.p.h)
- * - reorganised debug messages
- * - more comments, history, etc.
- * - mmc_init: configure the PSA if not done
- * - mmc_init: correct default value of level threshold for PCMCIA
- * - mmc_init: 2.00 detection better code for 2.00 initialization
- * - better info at startup
- * - IRQ setting (note: this setting is permanent)
- * - watchdog: change strategy (and solve module removal problems)
- * - add wireless extensions (ioctl and get_wireless_stats)
- * get/set nwid/frequency on fly, info for /proc/net/wireless
- * - more wireless extensions: SETSPY and GETSPY
- * - make wireless extensions optional
- * - private ioctl to set/get quality and level threshold, histogram
- * - remove /proc/net/wavelan
- * - suppress useless stuff from lp (net_local)
- * - kernel 2.1 support (copy_to/from_user instead of memcpy_to/fromfs)
- * - add message level (debug stuff in /var/adm/debug and errors not
- * displayed at console and still in /var/adm/messages)
- * - multi device support
- * - start fixing the probe (init code)
- * - more inlines
- * - man page
- * - many other minor details and cleanups
- *
- * Changes made in second pre-release:
- * -----------------------------------
- * - clean up init code (probe and module init)
- * - better multiple device support (module)
- * - name assignment (module)
- *
- * Changes made in third pre-release:
- * ----------------------------------
- * - be more conservative on timers
- * - preliminary support for multicast (I still lack some details)
- *
- * Changes made in fourth pre-release:
- * -----------------------------------
- * - multicast (revisited and finished)
- * - avoid reset in set_multicast_list (a really big hack)
- * if somebody could apply this code for other i82586 based drivers
- * - share onboard memory 75% RU and 25% CU (instead of 50/50)
- *
- * Changes made for release in 2.1.15:
- * -----------------------------------
- * - change the detection code for multi manufacturer code support
- *
- * Changes made for release in 2.1.17:
- * -----------------------------------
- * - update to wireless extensions changes
- * - silly bug in card initial configuration (psa_conf_status)
- *
- * Changes made for release in 2.1.27 & 2.0.30:
- * --------------------------------------------
- * - small bug in debug code (probably not the last one...)
- * - remove extern keyword for wavelan_probe()
- * - level threshold is now a standard wireless extension (version 4 !)
- * - modules parameters types (new module interface)
- *
- * Changes made for release in 2.1.36:
- * -----------------------------------
- * - byte count stats (courtesy of David Hinds)

- * - encryption setting from Brent Elphick (thanks a lot!)
- * - 'ioaddr' to 'u_long' for the Alpha (thanks to Stanislav Sinyagin)
- *
- * Other changes (not by me) :
- * -------------------------
- * - Spelling and gramar "rectification".
- *
- * Changes made for release in 2.0.37 & 2.2.2 :
- * ------------------------------------------
- * - Correct status in /proc/net/wireless
- * - Set PSA CRC to make PtP diagnostic tool happy (Bob Gray)
- * - Module init code don't fail if we found at least one card in
- * the address list (Karlis Peisenieks)
- * - Missing parenthesis (Christopher Peterson)
- * - Correct i82586 configuration parameters
- * - Encryption initialisation bug (Robert McCormack)
- * - New mac addresses detected in the probe
- * - Increase watchdog for busy environments
- *
- * Changes made for release in 2.0.38 & 2.2.7 :
- * ------------------------------------------
- * - Correct the reception logic to better report errors and avoid
- * sending bogus packet up the stack
- * - Delay RU config to avoid corrupting first received packet
- * - Change config completion code (to actually check something)
- * - Avoid reading out of bound in skbuf to transmit
- * - Rectify a lot of (useless) debugging code
- * - Change the way to `#ifdef SET_PSA_CRC'
- *
- * Changes made for release in 2.2.11 & 2.3.13 :
- * -------------------------------------------
- * - Change e-mail and web page addresses
- * - Watchdog timer is now correctly expressed in HZ, not in jiffies
- * - Add channel number to the list of frequencies in range
- * - Add the (short) list of bit-rates in range
- * - Developp a new sensitivity... (sens.value & sens.fixed)
- *
- * Changes made for release in 2.2.14 & 2.3.23 :
- * -------------------------------------------
- * - Fix check for root permission (break instead of exit)
- * - New nwid & encoding setting (Wireless Extension 9)
- *
- * Changes made for release in 2.3.49 :
- * ----------------------------------
- * - Indentation reformating (Alan)
- * - Update to new network API (softnet - 2.3.43) :
- * o replace dev->tbusy (Alan)
- * o replace dev->tstart (Alan)
- * o remove dev->interrupt (Alan)
- * o add SMP locking via spinlock in splxx (me)
- * o add spinlock in interrupt handler (me)
- * o use kernel watchdog instead of ours (me)
- * o increase watchdog timeout (kernel is more sensitive) (me)
- * o verify that all the changes make sense and work (me)
- * - Fixup a potential gotcha when reconfiguring and thighten a bit
- * the interactions with Tx queue.
- *
- * Changes made for release in 2.4.0 :
- * ---------------------------------
- * - Fix spinlock stupid bugs that I left in. The driver is now SMP
- * compliant and doesn't lockup at startup.
- *
- * Changes made for release in 2.5.2 :
- * ---------------------------------
- * - Use new driver API for Wireless Extensions :
- * o got rid of wavelan_ioctl()
- * o use a bunch of iw_handler instead
- *
- * Changes made for release in 2.5.35 :
- * ----------------------------------
- * - Set dev->trans_start to avoid filling the logs
- * - Handle better spurious/bogus interrupt
- * - Avoid deadlocks in mmc_out()/mmc_in()
- *
- * Wishes & dreams:
- * ----------------
- * - roaming (see Pcmcia driver)

-/*
- * This driver provide a Linux interface to the Wavelan Pcmcia hardware
- * The Wavelan is a product of Lucent (http://www.wavelan.com/).
- * This division was formerly part of NCR and then AT&T.
- * Wavelan are also distributed by DEC (RoamAbout DS)...
- *
- * To know how to use this driver, read the PCMCIA HOWTO.
- * If you want to exploit the many other fonctionalities, look comments
- * in the code...
- *
- * This driver is the result of the effort of many peoples (see below).
- */
-
-/* ------------------------ SPECIFIC NOTES ------------------------ */
-/*
- * Web page
- * --------
- * I try to maintain a web page with the Wireless LAN Howto at :
- * http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
- *
- * SMP
- * ---
- * We now are SMP compliant (I eventually fixed the remaining bugs).
- * The driver has been tested on a dual P6-150 and survived my usual
- * set of torture tests.
- * Anyway, I spent enough time chasing interrupt re-entrancy during
- * errors or reconfigure, and I designed the locked/unlocked sections
- * of the driver with great care, and with the recent addition of
- * the spinlock (thanks to the new API), we should be quite close to
- * the truth.
- * The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
- * but better safe than sorry (especially at 2 Mb/s ;-).
- *
- * I have also looked into disabling only our interrupt on the card
- * (via HACR) instead of all interrupts in the processor (via cli),
- * so that other driver are not impacted, and it look like it's
- * possible, but it's very tricky to do right (full of races). As
- * the gain would be mostly for SMP systems, it can wait...
- *
- * Debugging and options
- * ---------------------
- * You will find below a set of '#define" allowing a very fine control
- * on the driver behaviour and the debug messages printed.
- * The main options are :
- * o WAVELAN_ROAMING, for the experimental roaming support.
- * o SET_PSA_CRC, to have your card correctly recognised by
- * an access point and the Point-to-Point diagnostic tool.
- * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
- * (otherwise we always start afresh with some defaults)
- *
- * wavelan_cs.o is darn too big
- * -------------------------
- * That's true ! There is a very simple way to reduce the driver
- * object by 33% (yes !). Comment out the following line :
- * #include <linux/wireless.h>
- * Other compile options can also reduce the size of it...
- *
- * MAC address and hardware detection :
- * ----------------------------------
- * The detection code of the wavelan chech that the first 3
- * octets of the MAC address fit the company code. This type of
- * detection work well for AT&T cards (because the AT&T code is
- * hardcoded in wavelan_cs.h), but of course will fail for other
- * manufacturer.
- *
- * If you are sure that your card is derived from the wavelan,
- * here is the way to configure it :
- * 1) Get your MAC address
- * a) With your card utilities (wfreqsel, instconf, ...)
- * b) With the driver :
- * o compile the kernel with DEBUG_CONFIG_INFO enabled
- * o Boot and look the card messages
- * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan_cs.h)
- * 3) Compile & verify
- * 4) Send me the MAC code - I will include it in the next version...
- *
- */
-
-/* --------------------- WIRELESS EXTENSIONS --------------------- */
-/*
- * This driver is the first one to support "wireless extensions".
- * This set of extensions provide you some way to control the wireless
- * caracteristics of the hardware in a standard way and support for
- * applications for taking advantage of it (like Mobile IP).
- *
- * It might be a good idea as well to fetch the wireless tools to
- * configure the device and play a bit.

-/* --------------------------- HISTORY --------------------------- */
-/*
- * The history of the Wavelan drivers is as complicated as history of
- * the Wavelan itself (NCR -> AT&T -> Lucent).
- *
- * All started with Anders Klemets <klemets@paul.rutgers.edu>,
- * writing a Wavelan ISA driver for the MACH microkernel. Girish
- * Welling <welling@paul.rutgers.edu> had also worked on it.
- * Keith Moore modify this for the Pcmcia hardware.
- *
- * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
- * and add specific Pcmcia support (there is currently no equivalent
- * of the PCMCIA package under BSD...).
- *
- * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to FreeBSD.
- *
- * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
- *
- * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
- * (with help of the BSDI PCMCIA driver) for PCMCIA.
- * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
- * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
- * correctly 2.00 cards (2.4 GHz with frequency selection).
- * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
- * Pcmcia package (+ bug corrections).
- *
- * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
- * patchs to the Pcmcia driver. After, I added code in the ISA driver
- * for Wireless Extensions and full support of frequency selection
- * cards. Now, I'm doing the same to the Pcmcia driver + some
- * reorganisation.
- * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
- * much needed informations on the Wavelan hardware.

+/* ------------------------------------------------------------------------
+ * Video buffers queue management.
+ *
+ * Video queues is initialized by uvc_queue_init(). The function performs
+ * basic initialization of the uvc_video_queue struct and never fails.
+ *
+ * Video buffer allocation and freeing are performed by uvc_alloc_buffers and
+ * uvc_free_buffers respectively. The former acquires the video queue lock,
+ * while the later must be called with the lock held (so that allocation can
+ * free previously allocated buffers). Trying to free buffers that are mapped
+ * to user space will return -EBUSY.
+ *
+ * Video buffers are managed using two queues. However, unlike most USB video
+ * drivers that use an in queue and an out queue, we use a main queue to hold
+ * all queued buffers (both 'empty' and 'done' buffers), and an irq queue to
+ * hold empty buffers. This design (copied from video-buf) minimizes locking
+ * in interrupt, as only one queue is shared between interrupt and user
+ * contexts.
+ *
+ * Use cases
+ * ---------
+ *
+ * Unless stated otherwise, all operations that modify the irq buffers queue
+ * are protected by the irq spinlock.
+ *
+ * 1. The user queues the buffers, starts streaming and dequeues a buffer.
+ *
+ * The buffers are added to the main and irq queues. Both operations are
+ * protected by the queue lock, and the later is protected by the irq
+ * spinlock as well.
+ *
+ * The completion handler fetches a buffer from the irq queue and fills it
+ * with video data. If no buffer is available (irq queue empty), the handler
+ * returns immediately.
+ *
+ * When the buffer is full, the completion handler removes it from the irq
+ * queue, marks it as ready (UVC_BUF_STATE_DONE) and wakes its wait queue.
+ * At that point, any process waiting on the buffer will be woken up. If a
+ * process tries to dequeue a buffer after it has been marked ready, the
+ * dequeing will succeed immediately.
+ *
+ * 2. Buffers are queued, user is waiting on a buffer and the device gets
+ * disconnected.
+ *
+ * When the device is disconnected, the kernel calls the completion handler
+ * with an appropriate status code. The handler marks all buffers in the
+ * irq queue as being erroneous (UVC_BUF_STATE_ERROR) and wakes them up so
+ * that any process waiting on a buffer gets woken up.
+ *
+ * Waking up up the first buffer on the irq list is not enough, as the
+ * process waiting on the buffer might restart the dequeue operation
+ * immediately.

+ * - V4L2 buffer queueing: the driver will start streaming if video is not
+ * currently streaming.
+ *
+ * Race conditions between those 3 events might lead to deadlocks or other
+ * nasty side effects.
+ *
+ * The "video currently streaming" condition can't be detected by the irqqueue
+ * being empty, as a request can still be in flight. A separate "queue paused"
+ * flag is thus needed.
+ *
+ * The paused flag will be set when we try to retrieve the irqqueue head if the
+ * queue is empty, and cleared when we queue a buffer.
+ *
+ * The USB request completion handler will get the buffer at the irqqueue head
+ * under protection of the queue spinlock. If the queue is empty, the streaming
+ * paused flag will be set. Right after releasing the spinlock a userspace
+ * application can queue a buffer. The flag will then cleared, and the ioctl

+ * The number of stream contexts in the stream context array may be bigger than

+ * stream context array entries must be a power of two.
+ *
+ * We need a radix tree for mapping physical addresses of TRBs to which stream

+ * us which stream ring the TRB came from. We could store the stream ID in an
+ * event data TRB, but that doesn't help us for the cancellation case, since the
+ * endpoint may stop before it reaches that event data TRB.
+ *
+ * The radix tree maps the upper portion of the TRB DMA address to a ring
+ * segment that has the same upper portion of DMA addresses. For example, say I
+ * have segments of size 1KB, that are always 64-byte aligned. A segment may
+ * start at 0x10c91000 and end at 0x10c913f0. If I use the upper 10 bits, the
+ * key to the stream ID is 0x43244. I can use the DMA address of the TRB to
+ * pass the radix tree a key to get the right stream ID:
+ *
+ * 0x10c90fff >> 10 = 0x43243
+ * 0x10c912c0 >> 10 = 0x43244

+ *
+ * Obviously, only those TRBs with DMA addresses that are within the segment
+ * will make the radix tree return the stream ID for that ring.
+ *
+ * Caveats for the radix tree:
+ *
+ * The radix tree uses an unsigned long as a key pair. On 32-bit systems, an
+ * unsigned long will be 32-bits; on a 64-bit system an unsigned long will be
+ * 64-bits. Since we only request 32-bit DMA addresses, we can use that as the
+ * key on 32-bit or 64-bit systems (it would also be fine if we asked for 64-bit
+ * PCI DMA addresses on a 64-bit system). There might be a problem on 32-bit
+ * extended systems (where the DMA address can be bigger than 32-bits),
+ * if we allow the PCI dma mask to be bigger than 32-bits. So don't do that.

- * Since we can't queue our bulk write urbs (don't know why - it just
- * doesn't work), we can send down only one write urb at a time. The simplistic
- * approach taken by the generic usbserial driver will work, but it's not good
- * for performance. Therefore, we buffer upto URBDATA_QUEUE_MAX bytes of write
- * requests coming from the line discipline. This is done by chaining them
- * in lists of struct ipaq_packet, each packet holding a maximum of
- * PACKET_SIZE bytes.
- *
- * ipaq_write() can be called from bottom half context; hence we can't
- * allocate memory for packets there. So we initialize a pool of packets at
- * the first open and maintain a freelist.
- *
- * The value of PACKET_SIZE was empirically determined by
- * checking the maximum write sizes sent down by the ppp ldisc.
- * URBDATA_QUEUE_MAX is set to 64K, which is the maximum TCP window size.
