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

+                address of the currently active slave.  The MAC

+DM9000 Network driver
+=====================
+
+Copyright 2008 Simtec Electronics,
+          Ben Dooks <ben@simtec.co.uk> <ben-linux@fluff.org>
+
+
+Introduction
+------------
+
+This file describes how to use the DM9000 platform-device based network driver
+that is contained in the files drivers/net/dm9000.c and drivers/net/dm9000.h.
+
+The driver supports three DM9000 variants, the DM9000E which is the first chip
+supported as well as the newer DM9000A and DM9000B devices. It is currently
+maintained and tested by Ben Dooks, who should be CC: to any patches for this
+driver.
+
+
+Defining the platform device
+----------------------------
+
+The minimum set of resources attached to the platform device are as follows:
+
+    1) The physical address of the address register
+    2) The physical address of the data register
+    3) The IRQ line the device's interrupt pin is connected to.
+
+These resources should be specified in that order, as the ordering of the
+two address regions is important (the driver expects these to be address
+and then data).
+
+An example from arch/arm/mach-s3c2410/mach-bast.c is:
+
+static struct resource bast_dm9k_resource[] = {
+        [0] = {
+                .start = S3C2410_CS5 + BAST_PA_DM9000,
+                .end   = S3C2410_CS5 + BAST_PA_DM9000 + 3,
+                .flags = IORESOURCE_MEM,
+        },
+        [1] = {
+                .start = S3C2410_CS5 + BAST_PA_DM9000 + 0x40,
+                .end   = S3C2410_CS5 + BAST_PA_DM9000 + 0x40 + 0x3f,
+                .flags = IORESOURCE_MEM,
+        },
+        [2] = {
+                .start = IRQ_DM9000,
+                .end   = IRQ_DM9000,
+                .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,
+        }
+};
+
+static struct platform_device bast_device_dm9k = {
+        .name           = "dm9000",
+        .id             = 0,
+        .num_resources  = ARRAY_SIZE(bast_dm9k_resource),
+        .resource       = bast_dm9k_resource,
+};
+
+Note the setting of the IRQ trigger flag in bast_dm9k_resource[2].flags,
+as this will generate a warning if it is not present. The trigger from
+the flags field will be passed to request_irq() when registering the IRQ
+handler to ensure that the IRQ is setup correctly.
+
+This shows a typical platform device, without the optional configuration
+platform data supplied. The next example uses the same resources, but adds
+the optional platform data to pass extra configuration data:
+
+static struct dm9000_plat_data bast_dm9k_platdata = {
+        .flags          = DM9000_PLATF_16BITONLY,
+};
+
+static struct platform_device bast_device_dm9k = {
+        .name           = "dm9000",
+        .id             = 0,
+        .num_resources  = ARRAY_SIZE(bast_dm9k_resource),
+        .resource       = bast_dm9k_resource,
+        .dev            = {
+                .platform_data = &bast_dm9k_platdata,
+        }
+};
+
+The platform data is defined in include/linux/dm9000.h and described below.
+
+
+Platform data
+-------------
+
+Extra platform data for the DM9000 can describe the IO bus width to the
+device, whether or not an external PHY is attached to the device and
+the availability of an external configuration EEPROM.
+
+The flags for the platform data .flags field are as follows:
+
+DM9000_PLATF_8BITONLY
+
+        The IO should be done with 8bit operations.
+
+DM9000_PLATF_16BITONLY
+
+        The IO should be done with 16bit operations.
+
+DM9000_PLATF_32BITONLY
+
+        The IO should be done with 32bit operations.
+
+DM9000_PLATF_EXT_PHY
+
+        The chip is connected to an external PHY.
+
+DM9000_PLATF_NO_EEPROM
+
+        This can be used to signify that the board does not have an
+        EEPROM, or that the EEPROM should be hidden from the user.
+
+DM9000_PLATF_SIMPLE_PHY
+
+        Switch to using the simpler PHY polling method which does not
+        try and read the MII PHY state regularly. This is only available
+        when using the internal PHY. See the section on link state polling
+        for more information.
+
+        The config symbol DM9000_FORCE_SIMPLE_PHY_POLL, Kconfig entry
+        "Force simple NSR based PHY polling" allows this flag to be
+        forced on at build time.
+
+
+PHY Link state polling
+----------------------
+
+The driver keeps track of the link state and informs the network core
+about link (carrier) availablilty. This is managed by several methods
+depending on the version of the chip and on which PHY is being used.
+
+For the internal PHY, the original (and currently default) method is
+to read the MII state, either when the status changes if we have the
+necessary interrupt support in the chip or every two seconds via a
+periodic timer.
+
+To reduce the overhead for the internal PHY, there is now the option
+of using the DM9000_FORCE_SIMPLE_PHY_POLL config, or DM9000_PLATF_SIMPLE_PHY
+platform data option to read the summary information without the
+expensive MII accesses. This method is faster, but does not print
+as much information.
+
+When using an external PHY, the driver currently has to poll the MII
+link status as there is no method for getting an interrupt on link change.
+
+
+DM9000A / DM9000B
+-----------------
+
+These chips are functionally similar to the DM9000E and are supported easily
+by the same driver. The features are:
+
+   1) Interrupt on internal PHY state change. This means that the periodic
+      polling of the PHY status may be disabled on these devices when using
+      the internal PHY.
+
+   2) TCP/UDP checksum offloading, which the driver does not currently support.
+
+
+ethtool
+-------
+
+The driver supports the ethtool interface for access to the driver
+state information, the PHY state and the EEPROM.

 In This Release
 ===============
 
-This file describes the Linux* Base Driver for the Intel(R) PRO/10GbE Family 
-of Adapters, version 1.0.x.  
+This file describes the ixgb Linux Base Driver for the 10 Gigabit Intel(R)
+Network Connection.  This driver includes support for Itanium(R)2-based
+systems.
+
+For questions related to hardware requirements, refer to the documentation
+supplied with your 10 Gigabit adapter.  All hardware requirements listed apply
+to use with Linux.
+
+The following features are available in this kernel:
+ - Native VLANs
+ - Channel Bonding (teaming)
+ - SNMP
+
+Channel Bonding documentation can be found in the Linux kernel source:
+/Documentation/networking/bonding.txt
+
+The driver information previously displayed in the /proc filesystem is not
+supported in this release.  Alternatively, you can use ethtool (version 1.6
+or later), lspci, and ifconfig to obtain the same information.
+
+Instructions on updating ethtool can be found in the section "Additional
+Configurations" later in this document.
 
-For questions related to hardware requirements, refer to the documentation 
-supplied with your Intel PRO/10GbE adapter. All hardware requirements listed 
-apply to use with Linux.
 
 Identifying Your Adapter
 ========================
 
-To verify your Intel adapter is supported, find the board ID number on the 
-adapter. Look for a label that has a barcode and a number in the format  
-A12345-001. 
+The following Intel network adapters are compatible with the drivers in this
+release:

 Resolving Slow UDP Traffic
 --------------------------

+the network stack buffers as large as they need to be to support high UDP
+transfer rates.  One way to alleviate this problem is to allow more memory to

 can be increased significantly more if necessary for your application.
 
+
+Additional Configurations
+=========================
+
+  Configuring the Driver on Different Distributions
+  -------------------------------------------------
+  Configuring a network driver to load properly when the system is started is
+  distribution dependent. Typically, the configuration process involves adding
+  an alias line to /etc/modprobe.conf as well as editing other system startup
+  scripts and/or configuration files.  Many popular Linux distributions ship
+  with tools to make these changes for you.  To learn the proper way to
+  configure a network device for your system, refer to your distribution
+  documentation.  If during this process you are asked for the driver or module
+  name, the name for the Linux Base Driver for the Intel 10GbE Family of
+  Adapters is ixgb.
+
+  Viewing Link Messages
+  ---------------------
+  Link messages will not be displayed to the console if the distribution is
+  restricting system messages. In order to see network driver link messages on
+  your console, set dmesg to eight by entering the following:
+
+       dmesg -n 8
+
+  NOTE: This setting is not saved across reboots.
+
+
+  Jumbo Frames
+  ------------
+  The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
+  enabled by changing the MTU to a value larger than the default of 1500.
+  The maximum value for the MTU is 16114.  Use the ifconfig command to
+  increase the MTU size.  For example:
+
+        ifconfig ethx mtu 9000 up
+
+  The maximum MTU setting for Jumbo Frames is 16114.  This value coincides
+  with the maximum Jumbo Frames size of 16128.
+
+
+  Ethtool
+  -------
+  The driver utilizes the ethtool interface for driver configuration and
+  diagnostics, as well as displaying statistical information.  Ethtool
+  version 1.6 or later is required for this functionality.
+
+  The latest release of ethtool can be found from
+  http://sourceforge.net/projects/gkernel
+
+  NOTE: Ethtool 1.6 only supports a limited set of ethtool options. Support
+        for a more complete ethtool feature set can be enabled by upgrading
+        to the latest version.
+
+
+  NAPI
+  ----
+
+  NAPI (Rx polling mode) is supported in the ixgb driver.  NAPI is enabled
+  or disabled based on the configuration of the kernel.  see CONFIG_IXGB_NAPI
+
+  See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.
+
+
+Known Issues/Troubleshooting
+============================
+
+  NOTE: After installing the driver, if your Intel Network Connection is not
+  working, verify in the "In This Release" section of the readme that you have
+  installed the correct driver.
+
+  Intel(R) PRO/10GbE CX4 Server Adapter Cable Interoperability Issue with
+  Fujitsu XENPAK Module in SmartBits Chassis
+  ---------------------------------------------------------------------
+  Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
+  Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
+  chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
+  The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
+  Server adapter or the SmartBits. If this situation occurs using a different
+  cable assembly may resolve the issue.
+
+  CX4 Server Adapter Cable Interoperability Issues with HP Procurve 3400cl
+  Switch Port
+  ------------------------------------------------------------------------
+  Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
+  adapter is connected to an HP Procurve 3400cl switch port using short cables
+  (1 m or shorter). If this situation occurs, using a longer cable may resolve
+  the issue.
+
+  Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
+  Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
+  errors may be received either by the CX4 Server adapter or at the switch. If
+  this situation occurs, using a different cable assembly may resolve the issue.
+
+
+  Jumbo Frames System Requirement
+  -------------------------------
+  Memory allocation failures have been observed on Linux systems with 64 MB
+  of RAM or less that are running Jumbo Frames.  If you are using Jumbo
+  Frames, your system may require more than the advertised minimum
+  requirement of 64 MB of system memory.
+
+
+  Performance Degradation with Jumbo Frames
+  -----------------------------------------
+  Degradation in throughput performance may be observed in some Jumbo frames
+  environments.  If this is observed, increasing the application's socket buffer
+  size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
+  See the specific application manual and /usr/src/linux*/Documentation/
+  networking/ip-sysctl.txt for more details.
+
+
+  Allocating Rx Buffers when Using Jumbo Frames
+  ---------------------------------------------
+  Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
+  the available memory is heavily fragmented. This issue may be seen with PCI-X
+  adapters or with packet split disabled. This can be reduced or eliminated
+  by changing the amount of available memory for receive buffer allocation, by
+  increasing /proc/sys/vm/min_free_kbytes.
+
+
+  Multiple Interfaces on Same Ethernet Broadcast Network
+  ------------------------------------------------------
+  Due to the default ARP behavior on Linux, it is not possible to have
+  one system on two IP networks in the same Ethernet broadcast domain
+  (non-partitioned switch) behave as expected.  All Ethernet interfaces
+  will respond to IP traffic for any IP address assigned to the system.
+  This results in unbalanced receive traffic.
+
+  If you have multiple interfaces in a server, do either of the following:
+
+  - Turn on ARP filtering by entering:
+      echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+
+  - Install the interfaces in separate broadcast domains - either in
+    different switches or in a switch partitioned to VLANs.
+
+
+  UDP Stress Test Dropped Packet Issue
+  --------------------------------------
+  Under small packets UDP stress test with 10GbE driver, the Linux system
+  may drop UDP packets due to the fullness of socket buffers. You may want
+  to change the driver's Flow Control variables to the minimum value for
+  controlling packet reception.
+
+

+Introduction
+
+mac80211_hwsim is a Linux kernel module that can be used to simulate
+arbitrary number of IEEE 802.11 radios for mac80211. It can be used to
+test most of the mac80211 functionality and user space tools (e.g.,
+hostapd and wpa_supplicant) in a way that matches very closely with
+the normal case of using real WLAN hardware. From the mac80211 view
+point, mac80211_hwsim is yet another hardware driver, i.e., no changes
+to mac80211 are needed to use this testing tool.
+
+The main goal for mac80211_hwsim is to make it easier for developers
+to test their code and work with new features to mac80211, hostapd,
+and wpa_supplicant. The simulated radios do not have the limitations
+of real hardware, so it is easy to generate an arbitrary test setup
+and always reproduce the same setup for future tests. In addition,
+since all radio operation is simulated, any channel can be used in
+tests regardless of regulatory rules.
+
+mac80211_hwsim kernel module has a parameter 'radios' that can be used
+to select how many radios are simulated (default 2). This allows
+configuration of both very simply setups (e.g., just a single access
+point and a station) or large scale tests (multiple access points with
+hundreds of stations).
+
+mac80211_hwsim works by tracking the current channel of each virtual
+radio and copying all transmitted frames to all other radios that are
+currently enabled and on the same channel as the transmitting
+radio. Software encryption in mac80211 is used so that the frames are
+actually encrypted over the virtual air interface to allow more
+complete testing of encryption.
+
+A global monitoring netdev, hwsim#, is created independent of
+mac80211. This interface can be used to monitor all transmitted frames
+regardless of channel.
+
+
+Simple example
+
+This example shows how to use mac80211_hwsim to simulate two radios:
+one to act as an access point and the other as a station that
+associates with the AP. hostapd and wpa_supplicant are used to take
+care of WPA2-PSK authentication. In addition, hostapd is also
+processing access point side of association.
+
+Please note that the current Linux kernel does not enable AP mode, so a
+simple patch is needed to enable AP mode selection:

 Intro: Kernel support for multiqueue devices
 ---------------------------------------------------------
 
-Kernel support for multiqueue devices is only an API that is presented to the
-netdevice layer for base drivers to implement.  This feature is part of the
-core networking stack, and all network devices will be running on the
-multiqueue-aware stack.  If a base driver only has one queue, then these
-changes are transparent to that driver.
-
+Kernel support for multiqueue devices is always present.

 device is still operational.  netdev->queue_lock is still used when the device
 comes online or when it's completely shut down (unregister_netdev(), etc.).
 
-Finally, the base driver should indicate that it is a multiqueue device.  The
-feature flag NETIF_F_MULTI_QUEUE should be added to the netdev->features
-bitmap on device initialization.  Below is an example from e1000:
-

-                netdev->features |= NETIF_F_MULTI_QUEUE;
-#endif
-
-
-Section 2: Qdisc support for multiqueue devices
------------------------------------------------
-
-Currently two qdiscs support multiqueue devices.  A new round-robin qdisc,
-sch_rr, and sch_prio. The qdisc is responsible for classifying the skb's to
-bands and queues, and will store the queue mapping into skb->queue_mapping.
-Use this field in the base driver to determine which queue to send the skb
-to.
-
-sch_rr has been added for hardware that doesn't want scheduling policies from
-software, so it's a straight round-robin qdisc.  It uses the same syntax and
-classification priomap that sch_prio uses, so it should be intuitive to
-configure for people who've used sch_prio.
-
-In order to utilitize the multiqueue features of the qdiscs, the network
-device layer needs to enable multiple queue support.  This can be done by
-selecting NETDEVICES_MULTIQUEUE under Drivers.
-
-The PRIO qdisc naturally plugs into a multiqueue device.  If
-NETDEVICES_MULTIQUEUE is selected, then on qdisc load, the number of
-bands requested is compared to the number of queues on the hardware.  If they
-are equal, it sets a one-to-one mapping up between the queues and bands.  If
-they're not equal, it will not load the qdisc.  This is the same behavior
-for RR.  Once the association is made, any skb that is classified will have
-skb->queue_mapping set, which will allow the driver to properly queue skb's
-to multiple queues.
-
-
-Section 3: Brief howto using PRIO and RR for multiqueue devices
----------------------------------------------------------------
-
-The userspace command 'tc,' part of the iproute2 package, is used to configure
-qdiscs.  To add the PRIO qdisc to your network device, assuming the device is
-called eth0, run the following command:
-
-# tc qdisc add dev eth0 root handle 1: prio bands 4 multiqueue
-
-This will create 4 bands, 0 being highest priority, and associate those bands
-to the queues on your NIC.  Assuming eth0 has 4 Tx queues, the band mapping
-would look like:
-
-band 0 => queue 0
-band 1 => queue 1
-band 2 => queue 2
-band 3 => queue 3
-
-Traffic will begin flowing through each queue if your TOS values are assigning
-traffic across the various bands.  For example, ssh traffic will always try to
-go out band 0 based on TOS -> Linux priority conversion (realtime traffic),
-so it will be sent out queue 0.  ICMP traffic (pings) fall into the "normal"
-traffic classification, which is band 1.  Therefore pings will be send out
-queue 1 on the NIC.
-
-Note the use of the multiqueue keyword.  This is only in versions of iproute2
-that support multiqueue networking devices; if this is omitted when loading
-a qdisc onto a multiqueue device, the qdisc will load and operate the same
-if it were loaded onto a single-queue device (i.e. - sends all traffic to
-queue 0).
-
-Another alternative to multiqueue band allocation can be done by using the
-multiqueue option and specify 0 bands.  If this is the case, the qdisc will
-allocate the number of bands to equal the number of queues that the device
-reports, and bring the qdisc online.
-
-The behavior of tc filters remains the same, where it will override TOS priority
-classification.

+
+The rfkill switch subsystem exists to add a generic interface to circuitry that
+can enable or disable the signal output of a wireless *transmitter* of any
+type.  By far, the most common use is to disable radio-frequency transmitters.
 
-This is done by providing the user 3 possibilities:
- 1 - The rfkill system handles all events; userspace is not aware of events.
- 2 - The rfkill system handles all events; userspace is informed about the events.
- 3 - The rfkill system does not handle events; userspace handles all events.
+Note that disabling the signal output means that the the transmitter is to be
+made to not emit any energy when "blocked".  rfkill is not about blocking data
+transmissions, it is about blocking energy emission.

+attached to the system.
+
+The buttons to enable and disable the wireless transmitters are important in
 situations where the user is for example using his laptop on a location where
-wireless radios _must_ be disabled (e.g. airplanes).

+
+Because of this requirement, userspace support for the keys should not be made
+mandatory.  Because userspace might want to perform some additional smarter
+tasks when the key is pressed, rfkill provides userspace the possibility to
+take over the task to handle the key events.
+
+===============================================================================
+2: Implementation details
+
+The rfkill subsystem is composed of various components: the rfkill class, the
+rfkill-input module (an input layer handler), and some specific input layer
+events.
+
+The rfkill class provides kernel drivers with an interface that allows them to
+know when they should enable or disable a wireless network device transmitter.
+This is enabled by the CONFIG_RFKILL Kconfig option.
+
+The rfkill class support makes sure userspace will be notified of all state
+changes on rfkill devices through uevents.  It provides a notification chain
+for interested parties in the kernel to also get notified of rfkill state
+changes in other drivers.  It creates several sysfs entries which can be used
+by userspace.  See section "Userspace support".
+
+The rfkill-input module provides the kernel with the ability to implement a
+basic response when the user presses a key or button (or toggles a switch)
+related to rfkill functionality.  It is an in-kernel implementation of default
+policy of reacting to rfkill-related input events and neither mandatory nor
+required for wireless drivers to operate.  It is enabled by the
+CONFIG_RFKILL_INPUT Kconfig option.
+
+rfkill-input is a rfkill-related events input layer handler.  This handler will
+listen to all rfkill key events and will change the rfkill state of the
+wireless devices accordingly.  With this option enabled userspace could either
+do nothing or simply perform monitoring tasks.
+
+The rfkill-input module also provides EPO (emergency power-off) functionality
+for all wireless transmitters.  This function cannot be overridden, and it is
+always active.  rfkill EPO is related to *_RFKILL_ALL input layer events.
+
+
+Important terms for the rfkill subsystem:
+
+In order to avoid confusion, we avoid the term "switch" in rfkill when it is
+referring to an electronic control circuit that enables or disables a
+transmitter.  We reserve it for the physical device a human manipulates
+(which is an input device, by the way):
+
+rfkill switch:
+
+        A physical device a human manipulates.  Its state can be perceived by
+        the kernel either directly (through a GPIO pin, ACPI GPE) or by its
+        effect on a rfkill line of a wireless device.
+
+rfkill controller:
+
+        A hardware circuit that controls the state of a rfkill line, which a
+        kernel driver can interact with *to modify* that state (i.e. it has
+        either write-only or read/write access).
+
+rfkill line:
+
+        An input channel (hardware or software) of a wireless device, which
+        causes a wireless transmitter to stop emitting energy (BLOCK) when it
+        is active.  Point of view is extremely important here: rfkill lines are
+        always seen from the PoV of a wireless device (and its driver).
+
+soft rfkill line/software rfkill line:
+
+        A rfkill line the wireless device driver can directly change the state
+        of.  Related to rfkill_state RFKILL_STATE_SOFT_BLOCKED.
+
+hard rfkill line/hardware rfkill line:
+
+        A rfkill line that works fully in hardware or firmware, and that cannot
+        be overridden by the kernel driver.  The hardware device or the
+        firmware just exports its status to the driver, but it is read-only.
+        Related to rfkill_state RFKILL_STATE_HARD_BLOCKED.
+
+The enum rfkill_state describes the rfkill state of a transmitter:
+
+When a rfkill line or rfkill controller is in the RFKILL_STATE_UNBLOCKED state,
+the wireless transmitter (radio TX circuit for example) is *enabled*.  When the
+it is in the RFKILL_STATE_SOFT_BLOCKED or RFKILL_STATE_HARD_BLOCKED, the
+wireless transmitter is to be *blocked* from operating.
+
+RFKILL_STATE_SOFT_BLOCKED indicates that a call to toggle_radio() can change
+that state.  RFKILL_STATE_HARD_BLOCKED indicates that a call to toggle_radio()
+will not be able to change the state and will return with a suitable error if
+attempts are made to set the state to RFKILL_STATE_UNBLOCKED.
+
+RFKILL_STATE_HARD_BLOCKED is used by drivers to signal that the device is
+locked in the BLOCKED state by a hardwire rfkill line (typically an input pin
+that, when active, forces the transmitter to be disabled) which the driver
+CANNOT override.
+
+Full rfkill functionality requires two different subsystems to cooperate: the
+input layer and the rfkill class.  The input layer issues *commands* to the
+entire system requesting that devices registered to the rfkill class change
+state.  The way this interaction happens is not complex, but it is not obvious
+either:
+
+Kernel Input layer:
+
+        * Generates KEY_WWAN, KEY_WLAN, KEY_BLUETOOTH, SW_RFKILL_ALL, and
+          other such events when the user presses certain keys, buttons, or
+          toggles certain physical switches.
+
+        THE INPUT LAYER IS NEVER USED TO PROPAGATE STATUS, NOTIFICATIONS OR THE
+        KIND OF STUFF AN ON-SCREEN-DISPLAY APPLICATION WOULD REPORT.  It is
+        used to issue *commands* for the system to change behaviour, and these
+        commands may or may not be carried out by some kernel driver or
+        userspace application.  It follows that doing user feedback based only
+        on input events is broken, as there is no guarantee that an input event
+        will be acted upon.
+
+        Most wireless communication device drivers implementing rfkill
+        functionality MUST NOT generate these events, and have no reason to
+        register themselves with the input layer.  Doing otherwise is a common
+        misconception.  There is an API to propagate rfkill status change
+        information, and it is NOT the input layer.
+
+rfkill class:
+
+        * Calls a hook in a driver to effectively change the wireless
+          transmitter state;
+        * Keeps track of the wireless transmitter state (with help from
+          the driver);
+        * Generates userspace notifications (uevents) and a call to a
+          notification chain (kernel) when there is a wireless transmitter
+          state change;
+        * Connects a wireless communications driver with the common rfkill
+          control system, which, for example, allows actions such as
+          "switch all bluetooth devices offline" to be carried out by
+          userspace or by rfkill-input.
+
+        THE RFKILL CLASS NEVER ISSUES INPUT EVENTS.  THE RFKILL CLASS DOES
+        NOT LISTEN TO INPUT EVENTS.  NO DRIVER USING THE RFKILL CLASS SHALL
+        EVER LISTEN TO, OR ACT ON RFKILL INPUT EVENTS.  Doing otherwise is
+        a layering violation.
+
+        Most wireless data communication drivers in the kernel have just to
+        implement the rfkill class API to work properly.  Interfacing to the
+        input layer is not often required (and is very often a *bug*) on
+        wireless drivers.
+
+        Platform drivers often have to attach to the input layer to *issue*
+        (but never to listen to) rfkill events for rfkill switches, and also to
+        the rfkill class to export a control interface for the platform rfkill
+        controllers to the rfkill subsystem.  This does NOT mean the rfkill
+        switch is attached to a rfkill class (doing so is almost always wrong).
+        It just means the same kernel module is the driver for different
+        devices (rfkill switches and rfkill controllers).
+
+
+Userspace input handlers (uevents) or kernel input handlers (rfkill-input):

+        * In the rare platforms where this is required, synthesizes an input
+          event to command all *OTHER* rfkill devices to also change their

+
+
+===============================================================================
+3: Kernel driver guidelines
+
+Remember: point-of-view is everything for a driver that connects to the rfkill
+subsystem.  All the details below must be measured/perceived from the point of
+view of the specific driver being modified.
+
+The first thing one needs to know is whether his driver should be talking to
+the rfkill class or to the input layer.  In rare cases (platform drivers), it
+could happen that you need to do both, as platform drivers often handle a
+variety of devices in the same driver.
+
+Do not mistake input devices for rfkill controllers.  The only type of "rfkill
+switch" device that is to be registered with the rfkill class are those
+directly controlling the circuits that cause a wireless transmitter to stop
+working (or the software equivalent of them), i.e. what we call a rfkill
+controller.  Every other kind of "rfkill switch" is just an input device and
+MUST NOT be registered with the rfkill class.
+
+A driver should register a device with the rfkill class when ALL of the
+following conditions are met (they define a rfkill controller):
+
+1. The device is/controls a data communications wireless transmitter;
+
+2. The kernel can interact with the hardware/firmware to CHANGE the wireless
+   transmitter state (block/unblock TX operation);
+
+3. The transmitter can be made to not emit any energy when "blocked":
+   rfkill is not about blocking data transmissions, it is about blocking
+   energy emission;
+
+A driver should register a device with the input subsystem to issue
+rfkill-related events (KEY_WLAN, KEY_BLUETOOTH, KEY_WWAN, KEY_WIMAX,
+SW_RFKILL_ALL, etc) when ALL of the folowing conditions are met:
+
+1. It is directly related to some physical device the user interacts with, to
+   command the O.S./firmware/hardware to enable/disable a data communications
+   wireless transmitter.
+
+   Examples of the physical device are: buttons, keys and switches the user
+   will press/touch/slide/switch to enable or disable the wireless
+   communication device.
+
+2. It is NOT slaved to another device, i.e. there is no other device that
+   issues rfkill-related input events in preference to this one.
 
-The system inside the kernel has been split into 2 separate sections:
-        1 - RFKILL
-        2 - RFKILL_INPUT
+   Please refer to the corner cases and examples section for more details.
 
-The first option enables rfkill support and will make sure userspace will
-be notified of any events through the input device. It also creates several
-sysfs entries which can be used by userspace. See section "Userspace support".
+When in doubt, do not issue input events.  For drivers that should generate
+input events in some platforms, but not in others (e.g. b43), the best solution
+is to NEVER generate input events in the first place.  That work should be
+deferred to a platform-specific kernel module (which will know when to generate
+events through the rfkill notifier chain) or to userspace.  This avoids the
+usual maintenance problems with DMI whitelisting.
 
-The second option provides an rfkill input handler. This handler will
-listen to all rfkill key events and will toggle the radio accordingly.
-With this option enabled userspace could either do nothing or simply
-perform monitoring tasks.
 
+Corner cases and examples:
 ====================================
-2: Driver support
 
-To build a driver with rfkill subsystem support, the driver should
-depend on the Kconfig symbol RFKILL; it should _not_ depend on
-RKFILL_INPUT.
+1. If the device is an input device that, because of hardware or firmware,
+causes wireless transmitters to be blocked regardless of the kernel's will, it
+is still just an input device, and NOT to be registered with the rfkill class.
 
-Unless key events trigger an interrupt to which the driver listens, polling
-will be required to determine the key state changes. For this the input
-layer providers the input-polldev handler.
+2. If the wireless transmitter switch control is read-only, it is an input
+device and not to be registered with the rfkill class (and maybe not to be made
+an input layer event source either, see below).
 
-A driver should implement a few steps to correctly make use of the
-rfkill subsystem. First for non-polling drivers:
+3. If there is some other device driver *closer* to the actual hardware the
+user interacted with (the button/switch/key) to issue an input event, THAT is
+the device driver that should be issuing input events.
 
-        - rfkill_allocate()
-        - input_allocate_device()
-        - rfkill_register()
-        - input_register_device()
+E.g:
+  [RFKILL slider switch] -- [GPIO hardware] -- [WLAN card rf-kill input]
+                           (platform driver)    (wireless card driver)
+
+The user is closer to the RFKILL slide switch plaform driver, so the driver
+which must issue input events is the platform driver looking at the GPIO
+hardware, and NEVER the wireless card driver (which is just a slave).  It is
+very likely that there are other leaves than just the WLAN card rf-kill input
+(e.g. a bluetooth card, etc)...
+
+On the other hand, some embedded devices do this:
+
+  [RFKILL slider switch] -- [WLAN card rf-kill input]
+                             (wireless card driver)
+
+In this situation, the wireless card driver *could* register itself as an input
+device and issue rf-kill related input events... but in order to AVOID the need
+for DMI whitelisting, the wireless card driver does NOT do it.  Userspace (HAL)
+or a platform driver (that exists only on these embedded devices) will do the
+dirty job of issuing the input events.
+
+
+COMMON MISTAKES in kernel drivers, related to rfkill:
+====================================
+
+1. NEVER confuse input device keys and buttons with input device switches.
+
+  1a. Switches are always set or reset.  They report the current state
+      (on position or off position).
+
+  1b. Keys and buttons are either in the pressed or not-pressed state, and
+      that's it.  A "button" that latches down when you press it, and
+      unlatches when you press it again is in fact a switch as far as input
+      devices go.
+
+Add the SW_* events you need for switches, do NOT try to emulate a button using
+KEY_* events just because there is no such SW_* event yet.  Do NOT try to use,
+for example, KEY_BLUETOOTH when you should be using SW_BLUETOOTH instead.
+
+2. Input device switches (sources of EV_SW events) DO store their current state
+(so you *must* initialize it by issuing a gratuitous input layer event on
+driver start-up and also when resuming from sleep), and that state CAN be
+queried from userspace through IOCTLs.  There is no sysfs interface for this,
+but that doesn't mean you should break things trying to hook it to the rfkill
+class to get a sysfs interface :-)
+
+3. Do not issue *_RFKILL_ALL events by default, unless you are sure it is the
+correct event for your switch/button.  These events are emergency power-off
+events when they are trying to turn the transmitters off.  An example of an
+input device which SHOULD generate *_RFKILL_ALL events is the wireless-kill
+switch in a laptop which is NOT a hotkey, but a real switch that kills radios
+in hardware, even if the O.S. has gone to lunch.  An example of an input device
+which SHOULD NOT generate *_RFKILL_ALL events by default, is any sort of hot
+key that does nothing by itself, as well as any hot key that is type-specific
+(e.g. the one for WLAN).
+
+
+3.1 Guidelines for wireless device drivers
+------------------------------------------
+
+1. Each independent transmitter in a wireless device (usually there is only one
+transmitter per device) should have a SINGLE rfkill class attached to it.
+
+2. If the device does not have any sort of hardware assistance to allow the
+driver to rfkill the device, the driver should emulate it by taking all actions
+required to silence the transmitter.
+
+3. If it is impossible to silence the transmitter (i.e. it still emits energy,
+even if it is just in brief pulses, when there is no data to transmit and there
+is no hardware support to turn it off) do NOT lie to the users.  Do not attach
+it to a rfkill class.  The rfkill subsystem does not deal with data
+transmission, it deals with energy emission.  If the transmitter is emitting
+energy, it is not blocked in rfkill terms.
+
+4. It doesn't matter if the device has multiple rfkill input lines affecting
+the same transmitter, their combined state is to be exported as a single state
+per transmitter (see rule 1).
+
+This rule exists because users of the rfkill subsystem expect to get (and set,
+when possible) the overall transmitter rfkill state, not of a particular rfkill
+line.
+
+Example of a WLAN wireless driver connected to the rfkill subsystem:
+--------------------------------------------------------------------
+
+A certain WLAN card has one input pin that causes it to block the transmitter
+and makes the status of that input pin available (only for reading!) to the
+kernel driver.  This is a hard rfkill input line (it cannot be overridden by
+the kernel driver).
+
+The card also has one PCI register that, if manipulated by the driver, causes
+it to block the transmitter.  This is a soft rfkill input line.
+
+It has also a thermal protection circuitry that shuts down its transmitter if
+the card overheats, and makes the status of that protection available (only for
+reading!) to the kernel driver.  This is also a hard rfkill input line.
+
+If either one of these rfkill lines are active, the transmitter is blocked by
+the hardware and forced offline.
+
+The driver should allocate and attach to its struct device *ONE* instance of
+the rfkill class (there is only one transmitter).
+
+It can implement the get_state() hook, and return RFKILL_STATE_HARD_BLOCKED if
+either one of its two hard rfkill input lines are active.  If the two hard
+rfkill lines are inactive, it must return RFKILL_STATE_SOFT_BLOCKED if its soft
+rfkill input line is active.  Only if none of the rfkill input lines are
+active, will it return RFKILL_STATE_UNBLOCKED.
 
-For polling drivers:
+If it doesn't implement the get_state() hook, it must make sure that its calls
+to rfkill_force_state() are enough to keep the status always up-to-date, and it
+must do a rfkill_force_state() on resume from sleep.
 
+Every time the driver gets a notification from the card that one of its rfkill
+lines changed state (polling might be needed on badly designed cards that don't
+generate interrupts for such events), it recomputes the rfkill state as per
+above, and calls rfkill_force_state() to update it.
+
+The driver should implement the toggle_radio() hook, that:
+
+1. Returns an error if one of the hardware rfkill lines are active, and the
+caller asked for RFKILL_STATE_UNBLOCKED.
+
+2. Activates the soft rfkill line if the caller asked for state
+RFKILL_STATE_SOFT_BLOCKED.  It should do this even if one of the hard rfkill
+lines are active, effectively double-blocking the transmitter.
+
+3. Deactivates the soft rfkill line if none of the hardware rfkill lines are
+active and the caller asked for RFKILL_STATE_UNBLOCKED.
+
+===============================================================================
+4: Kernel API
+
+To build a driver with rfkill subsystem support, the driver should depend on
+(or select) the Kconfig symbol RFKILL; it should _not_ depend on RKFILL_INPUT.
+
+The hardware the driver talks to may be write-only (where the current state
+of the hardware is unknown), or read-write (where the hardware can be queried
+about its current state).
+
+The rfkill class will call the get_state hook of a device every time it needs
+to know the *real* current state of the hardware.  This can happen often.
+
+Some hardware provides events when its status changes.  In these cases, it is
+best for the driver to not provide a get_state hook, and instead register the
+rfkill class *already* with the correct status, and keep it updated using
+rfkill_force_state() when it gets an event from the hardware.
+
+There is no provision for a statically-allocated rfkill struct.  You must
+use rfkill_allocate() to allocate one.
+
+You should:
         - rfkill_allocate()
-        - input_allocate_polled_device()
+        - modify rfkill fields (flags, name)
+        - modify state to the current hardware state (THIS IS THE ONLY TIME
+          YOU CAN ACCESS state DIRECTLY)
         - rfkill_register()
-        - input_register_polled_device()
 
-When a key event has been detected, the correct event should be
-sent over the input device which has been registered by the driver.
+The only way to set a device to the RFKILL_STATE_HARD_BLOCKED state is through
+a suitable return of get_state() or through rfkill_force_state().
 
-====================================
-3: Userspace support
+When a device is in the RFKILL_STATE_HARD_BLOCKED state, the only way to switch
+it to a different state is through a suitable return of get_state() or through
+rfkill_force_state().
+
+If toggle_radio() is called to set a device to state RFKILL_STATE_SOFT_BLOCKED
+when that device is already at the RFKILL_STATE_HARD_BLOCKED state, it should
+not return an error.  Instead, it should try to double-block the transmitter,
+so that its state will change from RFKILL_STATE_HARD_BLOCKED to
+RFKILL_STATE_SOFT_BLOCKED should the hardware blocking cease.
 
-For each key an input device will be created which will send out the correct
-key event when the rfkill key has been pressed.
+Please refer to the source for more documentation.
+
+===============================================================================
+5: Userspace support
+
+rfkill devices issue uevents (with an action of "change"), with the following
+environment variables set:
+
+RFKILL_NAME
+RFKILL_STATE
+RFKILL_TYPE
+
+The ABI for these variables is defined by the sysfs attributes.  It is best
+to take a quick look at the source to make sure of the possible values.
+
+It is expected that HAL will trap those, and bridge them to DBUS, etc.  These
+events CAN and SHOULD be used to give feedback to the user about the rfkill
+status of the system.
+
+Input devices may issue events that are related to rfkill.  These are the
+various KEY_* events and SW_* events supported by rfkill-input.c.
+
+******IMPORTANT******
+When rfkill-input is ACTIVE, userspace is NOT TO CHANGE THE STATE OF AN RFKILL
+SWITCH IN RESPONSE TO AN INPUT EVENT also handled by rfkill-input, unless it
+has set to true the user_claim attribute for that particular switch.  This rule
+is *absolute*; do NOT violate it.
+******IMPORTANT******
+
+Userspace must not assume it is the only source of control for rfkill switches.
+Their state CAN and WILL change due to firmware actions, direct user actions,
+and the rfkill-input EPO override for *_RFKILL_ALL.
+
+When rfkill-input is not active, userspace must initiate a rfkill status
+change by writing to the "state" attribute in order for anything to happen.
+
+Take particular care to implement EV_SW SW_RFKILL_ALL properly.  When that
+switch is set to OFF, *every* rfkill device *MUST* be immediately put into the
+RFKILL_STATE_SOFT_BLOCKED state, no questions asked.
 
 The following sysfs entries will be created:
 
         name: Name assigned by driver to this key (interface or driver name).
         type: Name of the key type ("wlan", "bluetooth", etc).
-        state: Current state of the key. 1: On, 0: Off.
+        state: Current state of the transmitter
+                0: RFKILL_STATE_SOFT_BLOCKED
+                        transmitter is forced off, but one can override it
+                        by a write to the state attribute;
+                1: RFKILL_STATE_UNBLOCKED
+                        transmiter is NOT forced off, and may operate if
+                        all other conditions for such operation are met
+                        (such as interface is up and configured, etc);
+                2: RFKILL_STATE_HARD_BLOCKED
+                        transmitter is forced off by something outside of
+                        the driver's control.  One cannot set a device to
+                        this state through writes to the state attribute;
         claim: 1: Userspace handles events, 0: Kernel handles events
 
 Both the "state" and "claim" entries are also writable. For the "state" entry
-this means that when 1 or 0 is written all radios, not yet in the requested
-state, will be will be toggled accordingly.
+this means that when 1 or 0 is written, the device rfkill state (if not yet in

 set to 0, userspace should make sure that it listens for the input events or

+SW_RFKILL_ALL), you will need to use an IOCTL.  That information is not
+available through sysfs in a generic way at this time, and it is not available
+through the rfkill class AT ALL.

-
-1. General issues
-
-1.1 Why a new UHCI driver, we already have one?!?
-
-Correct, but its internal structure got more and more mixed up by the (still
-ongoing) efforts to get isochronous transfers (ISO) to work.
-Since there is an increasing need for reliable ISO-transfers (especially 
-for USB-audio needed by TS and for a DAB-USB-Receiver build by GA and DF), 
-this state was a bit unsatisfying in our opinion, so we've decided (based
-on knowledge and experiences with the old UHCI driver) to start 
-from scratch with a new approach, much simpler but at the same time more 
-powerful.
-It is inspired by the way Win98/Win2000 handles USB requests via URBs,
-but it's definitely 100% free of MS-code and doesn't crash while 
-unplugging an used ISO-device like Win98 ;-)
-Some code for HW setup and root hub management was taken from the 
-original UHCI driver, but heavily modified to fit into the new code.
-The invention of the basic concept, and major coding were completed in two 
-days (and nights) on the 16th and 17th of October 1999, now known as the
-great USB-October-Revolution started by GA, DF, and TS ;-)
-
-Since the concept is in no way UHCI dependent, we hope that it will also be 
-transferred to the OHCI-driver, so both drivers share a common API.
-
-1.2. Advantages and disadvantages
-
-+ All USB transfer types work now!
-+ Asynchronous operation
-+ Simple, but powerful interface (only two calls for start and cancel)
-+ Easy migration to the new API, simplified by a compatibility API
-+ Simple usage of ISO transfers
-+ Automatic linking of requests
-+ ISO transfers allow variable length for each frame and striping
-+ No CPU dependent and non-portable atomic memory access, no asm()-inlines

-- 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.
