+	  Select this to enable generic cpuidle driver for ARM64.
+	  It provides a generic idle driver whose idle states are configured
+	  at run-time through DT nodes. The CPUidle suspend backend is
+	  initialized by calling the CPU operations init idle hook
+	  provided by architecture code.

+/**
+ * DOC: Logical Rings, Logical Ring Contexts and Execlists
+ *
+ * Motivation:
+ * GEN8 brings an expansion of the HW contexts: "Logical Ring Contexts".
+ * These expanded contexts enable a number of new abilities, especially
+ * "Execlists" (also implemented in this file).
+ *
+ * One of the main differences with the legacy HW contexts is that logical
+ * ring contexts incorporate many more things to the context's state, like
+ * PDPs or ringbuffer control registers:
+ *
+ * The reason why PDPs are included in the context is straightforward: as
+ * PPGTTs (per-process GTTs) are actually per-context, having the PDPs
+ * contained there mean you don't need to do a ppgtt->switch_mm yourself,
+ * instead, the GPU will do it for you on the context switch.
+ *
+ * But, what about the ringbuffer control registers (head, tail, etc..)?
+ * shouldn't we just need a set of those per engine command streamer? This is
+ * where the name "Logical Rings" starts to make sense: by virtualizing the
+ * rings, the engine cs shifts to a new "ring buffer" with every context
+ * switch. When you want to submit a workload to the GPU you: A) choose your
+ * context, B) find its appropriate virtualized ring, C) write commands to it
+ * and then, finally, D) tell the GPU to switch to that context.
+ *
+ * Instead of the legacy MI_SET_CONTEXT, the way you tell the GPU to switch
+ * to a contexts is via a context execution list, ergo "Execlists".
+ *
+ * LRC implementation:
+ * Regarding the creation of contexts, we have:
+ *
+ * - One global default context.
+ * - One local default context for each opened fd.
+ * - One local extra context for each context create ioctl call.
+ *
+ * Now that ringbuffers belong per-context (and not per-engine, like before)
+ * and that contexts are uniquely tied to a given engine (and not reusable,
+ * like before) we need:
+ *
+ * - One ringbuffer per-engine inside each context.
+ * - One backing object per-engine inside each context.
+ *
+ * The global default context starts its life with these new objects fully
+ * allocated and populated. The local default context for each opened fd is
+ * more complex, because we don't know at creation time which engine is going
+ * to use them. To handle this, we have implemented a deferred creation of LR
+ * contexts:
+ *
+ * The local context starts its life as a hollow or blank holder, that only
+ * gets populated for a given engine once we receive an execbuffer. If later
+ * on we receive another execbuffer ioctl for the same context but a different
+ * engine, we allocate/populate a new ringbuffer and context backing object and
+ * so on.
+ *
+ * Finally, regarding local contexts created using the ioctl call: as they are
+ * only allowed with the render ring, we can allocate & populate them right
+ * away (no need to defer anything, at least for now).
+ *
+ * Execlists implementation:
+ * Execlists are the new method by which, on gen8+ hardware, workloads are
+ * submitted for execution (as opposed to the legacy, ringbuffer-based, method).
+ * This method works as follows:
+ *
+ * When a request is committed, its commands (the BB start and any leading or
+ * trailing commands, like the seqno breadcrumbs) are placed in the ringbuffer
+ * for the appropriate context. The tail pointer in the hardware context is not
+ * updated at this time, but instead, kept by the driver in the ringbuffer
+ * structure. A structure representing this request is added to a request queue
+ * for the appropriate engine: this structure contains a copy of the context's
+ * tail after the request was written to the ring buffer and a pointer to the
+ * context itself.
+ *
+ * If the engine's request queue was empty before the request was added, the
+ * queue is processed immediately. Otherwise the queue will be processed during
+ * a context switch interrupt. In any case, elements on the queue will get sent
+ * (in pairs) to the GPU's ExecLists Submit Port (ELSP, for short) with a
+ * globally unique 20-bits submission ID.
+ *
+ * When execution of a request completes, the GPU updates the context status
+ * buffer with a context complete event and generates a context switch interrupt.
+ * During the interrupt handling, the driver examines the events in the buffer:
+ * for each context complete event, if the announced ID matches that on the head
+ * of the request queue, then that request is retired and removed from the queue.
+ *
+ * After processing, if any requests were retired and the queue is not empty
+ * then a new execution list can be submitted. The two requests at the front of
+ * the queue are next to be submitted but since a context may not occur twice in
+ * an execution list, if subsequent requests have the same ID as the first then
+ * the two requests must be combined. This is done simply by discarding requests
+ * at the head of the queue until either only one requests is left (in which case
+ * we use a NULL second context) or the first two requests have unique IDs.
+ *
+ * By always executing the first two requests in the queue the driver ensures
+ * that the GPU is kept as busy as possible. In the case where a single context
+ * completes but a second context is still executing, the request for this second
+ * context will be at the head of the queue when we remove the first one. This
+ * request will then be resubmitted along with a new request for a different context,
+ * which will cause the hardware to continue executing the second request and queue
+ * the new request (the GPU detects the condition of a context getting preempted
+ * with the same context and optimizes the context switch flow by not doing
+ * preemption, but just sampling the new tail pointer).

-
-   When we submit operations to the GPU we pass a release reference to the GPU
-   with them, the release reference is then added to the release ring when
-   the GPU is finished with that particular operation and has removed it from
-   its tree.
-
-   So we have can have multiple outstanding non linear fences per object.
-
-   From a TTM POV we only care if the object has any outstanding releases on
-   it.
-
-   we wait until all outstanding releases are processeed.
-
-   sync object is just a list of release ids that represent that fence on
-   that buffer.
-
-   we just add new releases onto the sync object attached to the object.
-
-   This currently uses a radix tree to store the list of release ids.
-
-   For some reason every so often qxl hw fails to release, things go wrong.

+ * The risc program for each buffer works as follows: it starts with a simple

+ * buffer follows and at the end we have a JUMP back to the start + 12 (skipping
+ * the initial JUMP).
+ *
+ * This is the risc program of the first buffer to be queued if the active list
+ * is empty and it just keeps DMAing this buffer without generating any
+ * interrupts.
+ *
+ * If a new buffer is added then the initial JUMP in the code for that buffer
+ * will generate an interrupt which signals that the previous buffer has been
+ * DMAed successfully and that it can be returned to userspace.
+ *
+ * It also sets the final jump of the previous buffer to the start of the new
+ * buffer, thus chaining the new buffer into the DMA chain. This is a single
+ * atomic u32 write, so there is no race condition.
+ *
+ * The end-result of all this that you only get an interrupt when a buffer
+ * is ready, so the control flow is very easy.

+	  Enables a virtual video driver. This driver emulates a webcam,
+	  TV, S-Video and HDMI capture hardware, including VBI support for
+	  the SDTV inputs. Also video output, VBI output, radio receivers,
+	  transmitters and software defined radio capture is emulated.
+
+	  It is highly configurable and is ideal for testing applications.
+	  Error injection is supported to test rare errors that are hard
+	  to reproduce in real hardware.
+
+	  Say Y here if you want to test video apps or debug V4L devices.
+	  When in doubt, say N.

+ * video output buffer that is and which part of the video capture buffer
+ * so we can scale the video straight from the output buffer to the capture
+ * buffer without any intermediate steps.
+ *
+ * If we need to deal with an output overlay, then there is no choice and
+ * that intermediate step still has to be taken. For the output overlay
+ * support we calculate the intersection of the framebuffer and the overlay
+ * window (which may be partially or wholly outside of the framebuffer
+ * itself) and the intersection of that with loop_vid_copy (i.e. the part of
+ * the actual looped video that will be overlaid). The result is calculated
+ * both in framebuffer coordinates (loop_fb_copy) and compose_out coordinates
+ * (loop_vid_overlay). Finally calculate the part of the capture buffer that

+ * Closed: This state represents a mailbox that is in a standby state
+ *	   with interrupts disabled.  In this state the mailbox should not
+ *	   read the mailbox or write any data.  The only means of exiting
+ *	   this state is for the system to make the connect() call for the
+ *	   mailbox, it will then transition to the connect state.
+ * Connect: In this state the mailbox is seeking a connection.  It will
+ *	    post a connect message with no specified destination and will
+ *	    wait for a reply from the other side of the mailbox.  This state
+ *	    is exited when either a connect with the local mailbox as the

+ * The layout above describes the format for the header used in the PF/VF
+ * mailbox.  The header is broken out into the following fields:
+ * Type: There are 4 supported message types
+ *		0x8: Data header - used to transport message data
+ *		0xC: Connect header - used to establish connection
+ *		0xD: Disconnect header - used to tear down a connection
+ *		0xE: Error header - used to address message exceptions
+ * Tail: Tail index for local FIFO
+ *		Tail index actually consists of two parts.  The MSB of
+ *		the head is a loop tracker, it is 0 on an even numbered
+ *		loop through the FIFO, and 1 on the odd numbered loops.
+ *		To get the actual mailbox offset based on the tail it
+ *		is necessary to add bit 3 to bit 0 and clear bit 3.  This
+ *		gives us a valid range of 0x1 - 0xE.
+ * Head: Head index for remote FIFO
+ *		Head index follows the same format as the tail index.
+ * Rsvd0: Reserved 0 portion of the mailbox header
+ * CRC: Running CRC for all data since connect plus current message header
+ * Size: Maximum message size - Applies only to connect headers
+ *		The maximum message size is provided during connect to avoid
+ *		jamming the mailbox with messages that do not fit.
+ * Err_no: Error number - Applies only to error headers
+ *		The error number provides a indication of the type of error
+ *		experienced.

- * This API allows the Host to access Target registers directly
- * and relatively efficiently over PCIe.
- * This allows the Host to avoid extra overhead associated with
- * sending a message to firmware and waiting for a response message
- * from firmware, as is done on other interconnects.
- *
- * Yet there is some complexity with direct accesses because the
- * Target's power state is not known a priori. The Host must issue
- * special PCIe reads/writes in order to explicitly wake the Target
- * and to verify that it is awake and will remain awake.
- *
- * Usage:
+/* Target exposes its registers for direct access. However before host can
+ * access them it needs to make sure the target is awake (ath10k_pci_wake,
+ * ath10k_pci_wake_wait, ath10k_pci_is_awake). Once target is awake it won't go
+ * to sleep unless host tells it to (ath10k_pci_sleep).
  *
- *   Use ath10k_pci_read32 and ath10k_pci_write32 to access Target space.
- *   These calls must be bracketed by ath10k_pci_wake and
- *   ath10k_pci_sleep.  A single BEGIN/END pair is adequate for
- *   multiple READ/WRITE operations.
+ * If host tries to access target registers without waking it up it can
+ * scribble over host memory.
  *
- *   Use ath10k_pci_wake to put the Target in a state in
- *   which it is legal for the Host to directly access it. This
- *   may involve waking the Target from a low power state, which
- *   may take up to 2Ms!
- *
- *   Use ath10k_pci_sleep to tell the Target that as far as
- *   this code path is concerned, it no longer needs to remain
- *   directly accessible.  BEGIN/END is under a reference counter;
- *   multiple code paths may issue BEGIN/END on a single targid.
+ * If target is asleep waking it up may take up to even 2ms.

+ * ----------------------------------------
+ * - Description
+ * ----------------------------------------
+ *
+ * This driver is to be used with an external PowerPath Controller (LTC2952).
+ * Its function is to determine when a external shut down is triggered
+ * and react by properly shutting down the system.
+ *
+ * This driver expects a device tree with a ltc2952 entry for pin mapping.
+ *
+ * ----------------------------------------
+ * - GPIO
+ * ----------------------------------------
+ *
+ * The following GPIOs are used:
+ * - trigger (input)
+ *     A level change indicates the shut-down trigger. If it's state reverts
+ *     within the time-out defined by trigger_delay, the shut down is not
+ *     executed.
+ *
+ * - watchdog (output)
+ *     Once a shut down is triggered, the driver will toggle this signal,
+ *     with an internal (wde_interval) to stall the hardware shut down.
+ *
+ * - kill (output)
+ *     The last action during shut down is triggering this signalling, such
+ *     that the PowerPath Control will power down the hardware.
+ *
+ * ----------------------------------------
+ * - Interrupts
+ * ----------------------------------------
+ *
+ * The driver requires a non-shared, edge-triggered interrupt on the trigger
+ * GPIO.

-Devices: [Amplicon] PCI224 (amplc_pci224 or pci224),
-  PCI234 (amplc_pci224 or pci234)
-Updated: Wed, 22 Oct 2008 12:25:08 +0100
-Status: works, but see caveats
-
-Supports:
-
-  - ao_insn read/write
-  - ao_do_cmd mode with the following sources:
-
-    - start_src         TRIG_INT        TRIG_EXT
-    - scan_begin_src    TRIG_TIMER      TRIG_EXT
-    - convert_src       TRIG_NOW
-    - scan_end_src      TRIG_COUNT
-    - stop_src          TRIG_COUNT      TRIG_EXT        TRIG_NONE
-
-    The channel list must contain at least one channel with no repeated
-    channels.  The scan end count must equal the number of channels in
-    the channel list.
-
-    There is only one external trigger source so only one of start_src,
-    scan_begin_src or stop_src may use TRIG_EXT.
-
-Configuration options - PCI224:
-  [0] - PCI bus of device (optional).
-  [1] - PCI slot of device (optional).
-          If bus/slot is not specified, the first available PCI device
-          will be used.
-  [2] - Select available ranges according to jumper LK1.  All channels
-        are set to the same range:
-        0=Jumper position 1-2 (factory default), 4 software-selectable
-          internal voltage references, giving 4 bipolar and 4 unipolar
-          ranges:
-            [-10V,+10V], [-5V,+5V], [-2.5V,+2.5V], [-1.25V,+1.25V],
-            [0,+10V], [0,+5V], [0,+2.5V], [0,1.25V].
-        1=Jumper position 2-3, 1 external voltage reference, giving
-          1 bipolar and 1 unipolar range:
-            [-Vext,+Vext], [0,+Vext].
-
-Configuration options - PCI234:
-  [0] - PCI bus of device (optional).
-  [1] - PCI slot of device (optional).
-          If bus/slot is not specified, the first available PCI device
-          will be used.
-  [2] - Select internal or external voltage reference according to
-        jumper LK1.  This affects all channels:
-        0=Jumper position 1-2 (factory default), Vref=5V internal.
-        1=Jumper position 2-3, Vref=Vext external.
-  [3] - Select channel 0 range according to jumper LK2:
-        0=Jumper position 2-3 (factory default), range [-2*Vref,+2*Vref]
-          (10V bipolar when options[2]=0).
-        1=Jumper position 1-2, range [-Vref,+Vref]
-          (5V bipolar when options[2]=0).
-  [4] - Select channel 1 range according to jumper LK3: cf. options[3].
-  [5] - Select channel 2 range according to jumper LK4: cf. options[3].
-  [6] - Select channel 3 range according to jumper LK5: cf. options[3].
-
-Passing a zero for an option is the same as leaving it unspecified.
-
-Caveats:
-
-  1) All channels on the PCI224 share the same range.  Any change to the
-     range as a result of insn_write or a streaming command will affect
-     the output voltages of all channels, including those not specified
-     by the instruction or command.
-
-  2) For the analog output command,  the first scan may be triggered
-     falsely at the start of acquisition.  This occurs when the DAC scan
-     trigger source is switched from 'none' to 'timer' (scan_begin_src =
-     TRIG_TIMER) or 'external' (scan_begin_src == TRIG_EXT) at the start
-     of acquisition and the trigger source is at logic level 1 at the
-     time of the switch.  This is very likely for TRIG_TIMER.  For
-     TRIG_EXT, it depends on the state of the external line and whether
-     the CR_INVERT flag has been set.  The remaining scans are triggered
-     correctly.

+ *
+ * Output range selection - PCI234:
+ *
+ *   Output ranges on PCI234 are hardware-selectable according to jumper
+ *   LK1 which affects all channels, and jumpers LK2, LK3, LK4 and LK5
+ *   which affect channels 0, 1, 2 and 3 individually.  LK1 chooses between
+ *   an internal 5V reference and an external voltage reference (Vext).
+ *   LK2/3/4/5 choose (per channel) to double the reference or not according
+ *   to the following table:
+ *
+ *     LK1 position   LK2/3/4/5 pos  Comedi range
+ *     -------------  -------------  --------------
+ *     2-3 (factory)  1-2 (factory)  0: [-10V,+10V]

- * The previous block comment is used to automatically generate
- * documentation in Comedi and Comedilib.  The fields:
- *
- *  Driver: the name of the driver
- *  Description: a short phrase describing the driver.  Don't list boards.
- *  Devices: a full list of the boards that attempt to be supported by
- *    the driver.  Format is "(manufacturer) board name [comedi name]",
- *    where comedi_name is the name that is used to configure the board.
- *    See the comment near board_name: in the struct comedi_driver structure
- *    below.  If (manufacturer) or [comedi name] is missing, the previous
- *    value is used.
- *  Author: you
- *  Updated: date when the _documentation_ was last updated.  Use 'date -R'
- *    to get a value for this.
- *  Status: a one-word description of the status.  Valid values are:
- *    works - driver works correctly on most boards supported, and
- *      passes comedi_test.
- *    unknown - unknown.  Usually put there by ds.
- *    experimental - may not work in any particular release.  Author
- *      probably wants assistance testing it.
- *    bitrotten - driver has not been update in a long time, probably
- *      doesn't work, and probably is missing support for significant
- *      Comedi interface features.
- *    untested - author probably wrote it "blind", and is believed to
- *      work, but no confirmation.
- *
- * These headers should be followed by a blank line, and any comments
- * you wish to say about the driver.  The comment area is the place
- * to put any known bugs, limitations, unsupported features, supported
- * command triggers, whether or not commands are supported on particular
- * subdevices, etc.
- *
- * Somewhere in the comment should be information about configuration
- * options that are used with comedi_config.

-* change name of board_t to dgnc_board
-* split two assignments into the two assignments on two lines;
-  don't use two equals signs

 * remove unecessary error messages. Example kzalloc() has its

-This is a driver for the ET1310 network device.
-
-Based on the driver found at https://sourceforge.net/projects/et131x/
-
-Cleaned up immensely by Olaf Hartman and Christoph Hellwig <hch@infradead.org>
-
-Note, the powermanagement options were removed from the vendor provided
-driver as they did not build properly at the time.
-
-TODO:
-	- Look at reducing the number of spinlocks
-	- Simplify code in nic_rx_pkts(), when determining multicast_pkts_rcvd
-	- Implement NAPI support
-	- In et131x_tx(), don't return NETDEV_TX_BUSY, just drop the packet with kfree_skb().
-	- Reduce the number of split lines by careful consideration of variable names etc.
-
-Please send patches to:
-	Greg Kroah-Hartman <gregkh@linuxfoundation.org>
-	Mark Einon <mark.einon@gmail.com>

+Lustre Parallel Filesystem Client
+=================================
+
+The Lustre file system is an open-source, parallel file system
+that supports many requirements of leadership class HPC simulation
+environments.
+Born from from a research project at Carnegie Mellon University,
+the Lustre file system is a widely-used option in HPC.
+The Lustre file system provides a POSIX compliant file system interface,
+can scale to thousands of clients, petabytes of storage and
+hundreds of gigabytes per second of I/O bandwidth.
+
+Unlike shared disk storage cluster filesystems (e.g. OCFS2, GFS, GPFS),
+Lustre has independent Metadata and Data servers that clients can access
+in parallel to maximize performance.
+
+In order to use Lustre client you will need to download lustre client
+tools from
+https://downloads.hpdd.intel.com/public/lustre/latest-feature-release/
+the package name is lustre-client.
+
+You will need to install and configure your Lustre servers separately.
+
+Mount Syntax
+============
+After you installed the lustre-client tools including mount.lustre binary
+you can mount your Lustre filesystem with:
+
+mount -t lustre mgs:/fsname mnt
+
+where mgs is the host name or ip address of your Lustre MGS(management service)
+fsname is the name of the filesystem you would like to mount.
+
+
+Mount Options
+=============
+
+  noflock
+	Disable posix file locking (Applications trying to use
+	the functionality will get ENOSYS)
+
+  localflock
+	Enable local flock support, using only client-local flock
+	(faster, for applications that require flock but do not run
+	 on multiple nodes).
+
+  flock
+	Enable cluster-global posix file locking coherent across all
+	client nodes.
+
+  user_xattr, nouser_xattr
+	Support "user." extended attributes (or not)
+
+  user_fid2path, nouser_fid2path
+	Enable FID to path translation by regular users (or not)
+
+  checksum, nochecksum
+	Verify data consistency on the wire and in memory as it passes
+	between the layers (or not).
+
+  lruresize, nolruresize
+	Allow lock LRU to be controlled by memory pressure on the server
+	(or only 100 (default, controlled by lru_size proc parameter) locks
+	 per CPU per server on this client).
+
+  lazystatfs, nolazystatfs
+	Do not block in statfs() if some of the servers are down.
+
+  32bitapi
+	Shrink inode numbers to fit into 32 bits. This is necessary
+	if you plan to reexport Lustre filesystem from this client via
+	NFSv4.
+
+  verbose, noverbose
+	Enable mount/umount console messages (or not)
+
+More Information
+================
+You can get more information at
+OpenSFS website: http://lustre.opensfs.org/about/
+Intel HPDD wiki: https://wiki.hpdd.intel.com
+
+Out of tree Lustre client and server code is available at:

- *
- * The binary heap is a scalable data structure created using a binary tree. It
- * is capable of maintaining large sets of elements sorted usually by one or
- * more element properties, but really based on anything that can be used as a
- * binary predicate in order to determine the relevant ordering of any two nodes
- * that belong to the set. There is no search operation, rather the intention is
- * for the element of the lowest priority which will always be at the root of
- * the tree (as this is an implementation of a min-heap) to be removed by users
- * for consumption.
- *
- * Users of the heap should embed a \e cfs_binheap_node_t object instance on
- * every object of the set that they wish the binary heap instance to handle,
- * and (at a minimum) provide a cfs_binheap_ops_t::hop_compare() implementation
- * which is used by the heap as the binary predicate during its internal sorting
- * operations.
- *
- * The current implementation enforces no locking scheme, and so assumes the
- * user caters for locking between calls to insert, delete and lookup
- * operations. Since the only consumer for the data structure at this point
- * are NRS policies, and these operate on a per-CPT basis, binary heap instances
- * are tied to a specific CPT.

-
-Some code refactoring is still needed.
-
-TODO:
-
-> +++ b/drivers/bluetooth/hci_h4p.h
-
-can we please get the naming straight. File names do not start with
-hci_ anymore. We moved away from it since that term is too generic.
-
-> +struct hci_h4p_info {
-
-Can we please get rid of the hci_ prefix for everything. Copying from
-drivers that are over 10 years old is not a good idea. Please look at
-recent ones.
-
-> +     struct timer_list lazy_release;
-
-Timer? Not delayed work?
-

-
-These are a lot of public functions. Are they all really needed or can
-the code be done smart.
-
-> +static ssize_t hci_h4p_store_bdaddr(struct device *dev,

-> +{
-> +     struct hci_h4p_info *info = dev_get_drvdata(dev);
-
-Since none of these devices can function without having a valid
-address, the way this should work is that we should not register the
-HCI device when probing the platform device.
-    
-The HCI device should be registered once a valid address has been
-written into the sysfs file. I do not want to play the tricks with
-bringing up the device without a valid address.
-
-> +     hdev->close = hci_h4p_hci_close;
-> +     hdev->flush = hci_h4p_hci_flush;
-> +     hdev->send = hci_h4p_hci_send_frame;
-    
-It needs to use hdev->setup to load the firmware. I assume the
-firmware only needs to be loaded once. That is exactly what
-hdev->setup does. It gets executed once.
-    
-> +     set_bit(HCI_QUIRK_RESET_ON_CLOSE, &hdev->quirks);
-
-Is this quirk really needed? Normally only Bluetooth 1.1 and early

-> +     int not_valid;
-
-Has this actually been confirmed that we can just randomly set an
-address out of the Nokia range. I do not think so. This is a pretty
-bad idea.
-
-I have no interest in merging a driver with such a hack.
-

-
-Anybody every heard of memcmp or bacmp and BDADDR_ANY?
-

-
-And why does every single chip firmware does this differently. Seriously, this is a mess.
-

-> +             break;
-...
-> +}
-
-We have proper HCI sync command handling in recent kernels. I really
-do not know why this is hand coded these days. Check how the Intel
-firmware loading inside btusb.c does it.

-> +{ 
-> +     return __raw_readb(info->uart_base + (offset << 2));

-
-Inline in a *.c file for a non-static function. Makes no sense to me.

-TODO:
-- convert any remaining unusual variable types
-- find codes that can use %pM and %Nph formatting
-- checkpatch.pl fixes - most of the remaining ones are lines too long. Many
-  of them will require refactoring
-- merge Realtek's bugfixes and new features into the driver
-- Convert the versions of rtlwifi and btcoexist in drivers/net/wireless/rtlwifi/...
-  to work with the RTL8192EE
-- move this driver to drivers/net/wireless/rtlwifi
-
-Please send any patches to Greg Kroah-Hartman <gregkh@linux.com>,

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year  name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-Installation Instructions
-*************************
-
-Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
-2006, 2007 Free Software Foundation, Inc.
-
-This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package.  The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.
-
-     Running `configure' might take a while.  While running, it prints
-     some messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-  6. Often, you can also type `make uninstall' to remove the installed
-     files again.
-
-Compilers and Options
-=====================
-
-Some systems require unusual options for compilation or linking that the
-`configure' script does not know about.  Run `./configure --help' for
-details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-Installation Names
-==================
-
-By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc.  You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-There may be some features `configure' cannot figure out automatically,
-but needs to determine by the type of machine the package will run on.
-Usually, assuming the package is built to be run on the _same_
-architectures, `configure' can figure that out, but if it prints a
-message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-If you want to set default values for `configure' scripts to share, you
-can create a site shell script called `config.site' that gives default
-values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug.  Until the bug is fixed you can use this workaround:
-
-     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-`configure' recognizes the following options to control how it operates.
-
-`--help'
-`-h'
-     Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

----------------------------
-	SERVER SIDE
----------------------------
-Physically attach your USB devices to this host.
-
-    trois:# insmod path/to/usbip-core.ko
-    trois:# insmod path/to/usbip-host.ko
-    trois:# usbipd -D
-
-In another terminal, let's look up what USB devices are physically
-attached to this host.
-
-    trois:# usbip list -l
-    Local USB devices
-    =================
-     - busid 1-1 (05a9:a511)
-	     1-1:1.0 -> ov511
-
-     - busid 3-2 (0711:0902)
-	     3-2:1.0 -> none
-
-     - busid 3-3.1 (08bb:2702)
-	     3-3.1:1.0 -> snd-usb-audio
-	     3-3.1:1.1 -> snd-usb-audio
-
-     - busid 3-3.2 (04bb:0206)
-	     3-3.2:1.0 -> usb-storage
-
-     - busid 3-3 (0409:0058)
-	     3-3:1.0 -> hub
-
-     - busid 4-1 (046d:08b2)
-	     4-1:1.0 -> none
-	     4-1:1.1 -> none
-	     4-1:1.2 -> none
-
-     - busid 5-2 (058f:9254)
-	     5-2:1.0 -> hub
-
-A USB storage device of busid 3-3.2 is now bound to the usb-storage
-driver. To export this device, we first mark the device as
-"exportable"; the device is bound to the usbip-host driver. Please
-remember you can not export a USB hub.
-
-Mark the device of busid 3-3.2 as exportable:
-
-    trois:# usbip --debug bind --busid 3-3.2
-    ...
-    usbip debug: usbip_bind.c:162:[unbind_other] 3-3.2:1.0 -> usb-storage
-    ...
-    bind device on busid 3-3.2: complete
-
-    trois:# usbip list -l
-    Local USB devices
-    =================
-    ...
-
-     - busid 3-3.2 (04bb:0206)
-	     3-3.2:1.0 -> usbip-host
-    ...
-
----------------------------
-	CLIENT SIDE
----------------------------
-First, let's list available remote devices that are marked as
-exportable on the host.

-
-[Checklist]
-    - See 'Debug Tips' on the project wiki.
-	- http://usbip.wiki.sourceforge.net/how-to-debug-usbip
-    - usbip-host.ko must be bound to the target device.
-	- See /proc/bus/usb/devices and find "Driver=..." lines of the device.
-    - Shutdown firewall.
-	- usbip now uses TCP port 3240.
-    - Disable SELinux.
-    - Check the kernel and daemon messages.

-INTRODUCTION
-============
-
-Background
-----------
-
-An FPGA (Field Programmable Gate Array) is a piece of logic hardware, which
-can be programmed to become virtually anything that is usually found as a
-dedicated chipset: For instance, a display adapter, network interface card,
-or even a processor with its peripherals. FPGAs are the LEGO of hardware:
-Based upon certain building blocks, you make your own toys the way you like
-them. It's usually pointless to reimplement something that is already
-available on the market as a chipset, so FPGAs are mostly used when some
-special functionality is needed, and the production volume is relatively low
-(hence not justifying the development of an ASIC).
-
-The challenge with FPGAs is that everything is implemented at a very low
-level, even lower than assembly language. In order to allow FPGA designers to
-focus on their specific project, and not reinvent the wheel over and over
-again, pre-designed building blocks, IP cores, are often used. These are the
-FPGA parallels of library functions. IP cores may implement certain
-mathematical functions, a functional unit (e.g. a USB interface), an entire
-processor (e.g. ARM) or anything that might come handy. Think of them as a
-building block, with electrical wires dangling on the sides for connection to
-other blocks.
-
-One of the daunting tasks in FPGA design is communicating with a fullblown
-operating system (actually, with the processor running it): Implementing the
-low-level bus protocol and the somewhat higher-level interface with the host
-(registers, interrupts, DMA etc.) is a project in itself. When the FPGA's
-function is a well-known one (e.g. a video adapter card, or a NIC), it can
-make sense to design the FPGA's interface logic specifically for the project.
-A special driver is then written to present the FPGA as a well-known interface
-to the kernel and/or user space. In that case, there is no reason to treat the
-FPGA differently than any device on the bus.
-
-It's however common that the desired data communication doesn't fit any well-
-known peripheral function. Also, the effort of designing an elegant
-abstraction for the data exchange is often considered too big. In those cases,
-a quicker and possibly less elegant solution is sought: The driver is
-effectively written as a user space program, leaving the kernel space part
-with just elementary data transport. This still requires designing some
-interface logic for the FPGA, and write a simple ad-hoc driver for the kernel.
-
-Xillybus Overview
------------------
-
-Xillybus is an IP core and a Linux driver. Together, they form a kit for
-elementary data transport between an FPGA and the host, providing pipe-like
-data streams with a straightforward user interface. It's intended as a low-
-effort solution for mixed FPGA-host projects, for which it makes sense to
-have the project-specific part of the driver running in a user-space program.
-
-Since the communication requirements may vary significantly from one FPGA
-project to another (the number of data pipes needed in each direction and
-their attributes), there isn't one specific chunk of logic being the Xillybus
-IP core. Rather, the IP core is configured and built based upon a
-specification given by its end user.
-
-Xillybus presents independent data streams, which resemble pipes or TCP/IP
-communication to the user. At the host side, a character device file is used
-just like any pipe file. On the FPGA side, hardware FIFOs are used to stream
-the data. This is contrary to a common method of communicating through fixed-
-sized buffers (even though such buffers are used by Xillybus under the hood).
-There may be more than a hundred of these streams on a single IP core, but
-also no more than one, depending on the configuration.
-
-In order to ease the deployment of the Xillybus IP core, it contains a simple
-data structure which completely defines the core's configuration. The Linux
-driver fetches this data structure during its initialization process, and sets
-up the DMA buffers and character devices accordingly. As a result, a single
-driver is used to work out of the box with any Xillybus IP core.
-
-The data structure just mentioned should not be confused with PCI's
-configuration space or the Flattened Device Tree.
-
-USAGE
-=====
-
-User interface
---------------
-
-On the host, all interface with Xillybus is done through /dev/xillybus_*
-device files, which are generated automatically as the drivers loads. The
-names of these files depend on the IP core that is loaded in the FPGA (see
-Probing below). To communicate with the FPGA, open the device file that
-corresponds to the hardware FIFO you want to send data or receive data from,
-and use plain write() or read() calls, just like with a regular pipe. In
-particular, it makes perfect sense to go:
-
-$ cat mydata > /dev/xillybus_thisfifo
-
-$ cat /dev/xillybus_thatfifo > hisdata
-
-possibly pressing CTRL-C as some stage, even though the xillybus_* pipes have
-the capability to send an EOF (but may not use it).
-
-The driver and hardware are designed to behave sensibly as pipes, including:
-
-* Supporting non-blocking I/O (by setting O_NONBLOCK on open() ).
-
-* Supporting poll() and select().
-
-* Being bandwidth efficient under load (using DMA) but also handle small
-  pieces of data sent across (like TCP/IP) by autoflushing.
-
-A device file can be read only, write only or bidirectional. Bidirectional
-device files are treated like two independent pipes (except for sharing a
-"channel" structure in the implementation code).
-
-Synchronization
----------------
-
-Xillybus pipes are configured (on the IP core) to be either synchronous or
-asynchronous. For a synchronous pipe, write() returns successfully only after
-some data has been submitted and acknowledged by the FPGA. This slows down
-bulk data transfers, and is nearly impossible for use with streams that
-require data at a constant rate: There is no data transmitted to the FPGA
-between write() calls, in particular when the process loses the CPU.
-
-When a pipe is configured asynchronous, write() returns if there was enough
-room in the buffers to store any of the data in the buffers.
-
-For FPGA to host pipes, asynchronous pipes allow data transfer from the FPGA
-as soon as the respective device file is opened, regardless of if the data
-has been requested by a read() call. On synchronous pipes, only the amount
-of data requested by a read() call is transmitted.
-
-In summary, for synchronous pipes, data between the host and FPGA is
-transmitted only to satisfy the read() or write() call currently handled
-by the driver, and those calls wait for the transmission to complete before
-returning.
-
-Note that the synchronization attribute has nothing to do with the possibility
-that read() or write() completes less bytes than requested. There is a
-separate configuration flag ("allowpartial") that determines whether such a
-partial completion is allowed.
-
-Seekable pipes
---------------
-
-A synchronous pipe can be configured to have the stream's position exposed
-to the user logic at the FPGA. Such a pipe is also seekable on the host API.
-With this feature, a memory or register interface can be attached on the
-FPGA side to the seekable stream. Reading or writing to a certain address in
-the attached memory is done by seeking to the desired address, and calling
-read() or write() as required.
-
-
-INTERNALS
-=========
-
-Source code organization
-------------------------
-
-The Xillybus driver consists of a core module, xillybus_core.c, and modules
-that depend on the specific bus interface (xillybus_of.c and xillybus_pcie.c).
-
-The bus specific modules are those probed when a suitable device is found by
-the kernel. Since the DMA mapping and synchronization functions, which are bus
-dependent by their nature, are used by the core module, a
-xilly_endpoint_hardware structure is passed to the core module on
-initialization. This structure is populated with pointers to wrapper functions
-which execute the DMA-related operations on the bus.
-
-Pipe attributes
----------------
-
-Each pipe has a number of attributes which are set when the FPGA component
-(IP core) is built. They are fetched from the IDT (the data structure which
-defines the core's configuration, see Probing below) by xilly_setupchannels()
-in xillybus_core.c as follows:
-
-* is_writebuf: The pipe's direction. A non-zero value means it's an FPGA to
-  host pipe (the FPGA "writes").
-
-* channelnum: The pipe's identification number in communication between the
-  host and FPGA.
-
-* format: The underlying data width. See Data Granularity below.
-
-* allowpartial: A non-zero value means that a read() or write() (whichever
-  applies) may return with less than the requested number of bytes. The common
-  choice is a non-zero value, to match standard UNIX behavior.
-
-* synchronous: A non-zero value means that the pipe is synchronous. See
-  Syncronization above.
-
-* bufsize: Each DMA buffer's size. Always a power of two.
-
-* bufnum: The number of buffers allocated for this pipe. Always a power of two.
-
-* exclusive_open: A non-zero value forces exclusive opening of the associated
-  device file. If the device file is bidirectional, and already opened only in
-  one direction, the opposite direction may be opened once.
-
-* seekable: A non-zero value indicates that the pipe is seekable. See
-  Seekable pipes above.
-
-* supports_nonempty: A non-zero value (which is typical) indicates that the
-  hardware will send the messages that are necessary to support select() and
-  poll() for this pipe.
-
-Host never reads from the FPGA
-------------------------------
-
-Even though PCI Express is hotpluggable in general, a typical motherboard
-doesn't expect a card to go away all of the sudden. But since the PCIe card
-is based upon reprogrammable logic, a sudden disappearance from the bus is
-quite likely as a result of an accidental reprogramming of the FPGA while the
-host is up. In practice, nothing happens immediately in such a situation. But
-if the host attempts to read from an address that is mapped to the PCI Express
-device, that leads to an immediate freeze of the system on some motherboards,
-even though the PCIe standard requires a graceful recovery.
-
-In order to avoid these freezes, the Xillybus driver refrains completely from
-reading from the device's register space. All communication from the FPGA to
-the host is done through DMA. In particular, the Interrupt Service Routine
-doesn't follow the common practice of checking a status register when it's
-invoked. Rather, the FPGA prepares a small buffer which contains short
-messages, which inform the host what the interrupt was about.
-
-This mechanism is used on non-PCIe buses as well for the sake of uniformity.
-
-
-Channels, pipes, and the message channel
-----------------------------------------
-
-Each of the (possibly bidirectional) pipes presented to the user is allocated
-a data channel between the FPGA and the host. The distinction between channels
-and pipes is necessary only because of channel 0, which is used for interrupt-
-related messages from the FPGA, and has no pipe attached to it.
-
-Data streaming
---------------
-
-Even though a non-segmented data stream is presented to the user at both
-sides, the implementation relies on a set of DMA buffers which is allocated
-for each channel. For the sake of illustration, let's take the FPGA to host
-direction: As data streams into the respective channel's interface in the
-FPGA, the Xillybus IP core writes it to one of the DMA buffers. When the
-buffer is full, the FPGA informs the host about that (appending a
-XILLYMSG_OPCODE_RELEASEBUF message channel 0 and sending an interrupt if
-necessary). The host responds by making the data available for reading through
-the character device. When all data has been read, the host writes on the
-the FPGA's buffer control register, allowing the buffer's overwriting. Flow
-control mechanisms exist on both sides to prevent underflows and overflows.
-
-This is not good enough for creating a TCP/IP-like stream: If the data flow
-stops momentarily before a DMA buffer is filled, the intuitive expectation is
-that the partial data in buffer will arrive anyhow, despite the buffer not
-being completed. This is implemented by adding a field in the
-XILLYMSG_OPCODE_RELEASEBUF message, through which the FPGA informs not just
-which buffer is submitted, but how much data it contains.
-
-But the FPGA will submit a partially filled buffer only if directed to do so
-by the host. This situation occurs when the read() method has been blocking
-for XILLY_RX_TIMEOUT jiffies (currently 10 ms), after which the host commands
-the FPGA to submit a DMA buffer as soon as it can. This timeout mechanism
-balances between bus bandwidth efficiency (preventing a lot of partially
-filled buffers being sent) and a latency held fairly low for tails of data.
-
-A similar setting is used in the host to FPGA direction. The handling of
-partial DMA buffers is somewhat different, though. The user can tell the
-driver to submit all data it has in the buffers to the FPGA, by issuing a
-write() with the byte count set to zero. This is similar to a flush request,
-but it doesn't block. There is also an autoflushing mechanism, which triggers
-an equivalent flush roughly XILLY_RX_TIMEOUT jiffies after the last write().
-This allows the user to be oblivious about the underlying buffering mechanism
-and yet enjoy a stream-like interface.
-
-Note that the issue of partial buffer flushing is irrelevant for pipes having
-the "synchronous" attribute nonzero, since synchronous pipes don't allow data
-to lay around in the DMA buffers between read() and write() anyhow.
-
-Data granularity
-----------------
-
-The data arrives or is sent at the FPGA as 8, 16 or 32 bit wide words, as
-configured by the "format" attribute. Whenever possible, the driver attempts
-to hide this when the pipe is accessed differently from its natural alignment.
-For example, reading single bytes from a pipe with 32 bit granularity works
-with no issues. Writing single bytes to pipes with 16 or 32 bit granularity
-will also work, but the driver can't send partially completed words to the
-FPGA, so the transmission of up to one word may be held until it's fully
-occupied with user data.
-
-This somewhat complicates the handling of host to FPGA streams, because
-when a buffer is flushed, it may contain up to 3 bytes don't form a word in
-the FPGA, and hence can't be sent. To prevent loss of data, these leftover
-bytes need to be moved to the next buffer. The parts in xillybus_core.c
-that mention "leftovers" in some way are related to this complication.
-
-Probing
--------
-
-As mentioned earlier, the number of pipes that are created when the driver
-loads and their attributes depend on the Xillybus IP core in the FPGA. During
-the driver's initialization, a blob containing configuration info, the
-Interface Description Table (IDT), is sent from the FPGA to the host. The
-bootstrap process is done in three phases:
-
-1. Acquire the length of the IDT, so a buffer can be allocated for it. This
-   is done by sending a quiesce command to the device, since the acknowledge
-   for this command contains the IDT's buffer length.
-
-2. Acquire the IDT itself.
-
-3. Create the interfaces according to the IDT.
-
-Buffer allocation
------------------
-
-In order to simplify the logic that prevents illegal boundary crossings of
-PCIe packets, the following rule applies: If a buffer is smaller than 4kB,
-it must not cross a 4kB boundary. Otherwise, it must be 4kB aligned. The
-xilly_setupchannels() functions allocates these buffers by requesting whole
-pages from the kernel, and diving them into DMA buffers as necessary. Since
-all buffers' sizes are powers of two, it's possible to pack any set of such
-buffers, with a maximal waste of one page of memory.
-
-All buffers are allocated when the driver is loaded. This is necessary,
-since large continuous physical memory segments are sometimes requested,
-which are more likely to be available when the system is freshly booted.
-
-The allocation of buffer memory takes place in the same order they appear in
-the IDT. The driver relies on a rule that the pipes are sorted with decreasing
-buffer size in the IDT. If a requested buffer is larger or equal to a page,
-the necessary number of pages is requested from the kernel, and these are
-used for this buffer. If the requested buffer is smaller than a page, one
-single page is requested from the kernel, and that page is partially used.
-Or, if there already is a partially used page at hand, the buffer is packed
-into that page. It can be shown that all pages requested from the kernel
-(except possibly for the last) are 100% utilized this way.
-
-The "nonempty" message (supporting poll)
----------------------------------------
-
-In order to support the "poll" method (and hence select() ), there is a small
-catch regarding the FPGA to host direction: The FPGA may have filled a DMA
-buffer with some data, but not submitted that buffer. If the host waited for
-the buffer's submission by the FPGA, there would be a possibility that the
-FPGA side has sent data, but a select() call would still block, because the
-host has not received any notification about this. This is solved with
-XILLYMSG_OPCODE_NONEMPTY messages sent by the FPGA when a channel goes from
-completely empty to containing some data.
-
-These messages are used only to support poll() and select(). The IP core can
-be configured not to send them for a slight reduction of bandwidth.
