+What:		/dev/fw[0-9]+
+Date:		May 2007
+KernelVersion:	2.6.22
+Contact:	linux1394-devel@lists.sourceforge.net
+Description:
+		The character device files /dev/fw* are the interface between
+		firewire-core and IEEE 1394 device drivers implemented in
+		userspace.  The ioctl(2)- and read(2)-based ABI is defined and
+		documented in <linux/firewire-cdev.h>.
+
+		This ABI offers most of the features which firewire-core also
+		exposes to kernelspace IEEE 1394 drivers.
+
+		Each /dev/fw* is associated with one IEEE 1394 node, which can
+		be remote or local nodes.  Operations on a /dev/fw* file have
+		different scope:
+		  - The 1394 node which is associated with the file:
+			  - Asynchronous request transmission
+			  - Get the Configuration ROM
+			  - Query node ID
+			  - Query maximum speed of the path between this node
+			    and local node
+		  - The 1394 bus (i.e. "card") to which the node is attached to:
+			  - Isochronous stream transmission and reception
+			  - Asynchronous stream transmission and reception
+			  - Asynchronous broadcast request transmission
+			  - PHY packet transmission and reception
+			  - Allocate, reallocate, deallocate isochronous
+			    resources (channels, bandwidth) at the bus's IRM
+			  - Query node IDs of local node, root node, IRM, bus
+			    manager
+			  - Query cycle time
+			  - Bus reset initiation, bus reset event reception
+		  - All 1394 buses:
+			  - Allocation of IEEE 1212 address ranges on the local
+			    link layers, reception of inbound requests to such
+			    an address range, asynchronous response transmission
+			    to inbound requests
+			  - Addition of descriptors or directories to the local
+			    nodes' Configuration ROM
+
+		Due to the different scope of operations and in order to let
+		userland implement different access permission models, some
+		operations are restricted to /dev/fw* files that are associated
+		with a local node:
+			  - Addition of descriptors or directories to the local
+			    nodes' Configuration ROM
+			  - PHY packet transmission and reception
+
+		A /dev/fw* file remains associated with one particular node
+		during its entire life time.  Bus topology changes, and hence
+		node ID changes, are tracked by firewire-core.  ABI users do not
+		need to be aware of topology.
+
+		The following file operations are supported:
+
+		open(2)
+		Currently the only useful flags are O_RDWR.
+
+		ioctl(2)
+		Initiate various actions.  Some take immediate effect, others
+		are performed asynchronously while or after the ioctl returns.
+		See the inline documentation in <linux/firewire-cdev.h> for
+		descriptions of all ioctls.
+
+		poll(2), select(2), epoll_wait(2) etc.
+		Watch for events to become available to be read.
+
+		read(2)
+		Receive various events.  There are solicited events like
+		outbound asynchronous transaction completion or isochronous
+		buffer completion, and unsolicited events such as bus resets,
+		request reception, or PHY packet reception.  Always use a read
+		buffer which is large enough to receive the largest event that
+		could ever arrive.  See <linux/firewire-cdev.h> for descriptions
+		of all event types and for which ioctls affect reception of
+		events.
+
+		mmap(2)
+		Allocate a DMA buffer for isochronous reception or transmission
+		and map it into the process address space.  The arguments should
+		be used as follows:  addr = NULL, length = the desired buffer
+		size, i.e. number of packets times size of largest packet,
+		prot = at least PROT_READ for reception and at least PROT_WRITE
+		for transmission, flags = MAP_SHARED, fd = the handle to the
+		/dev/fw*, offset = 0.
+
+		Isochronous reception works in packet-per-buffer fashion except
+		for multichannel reception which works in buffer-fill mode.
+
+		munmap(2)
+		Unmap the isochronous I/O buffer from the process address space.
+
+		close(2)
+		Besides stopping and freeing I/O contexts that were associated
+		with the file descriptor, back out any changes to the local
+		nodes' Configuration ROM.  Deallocate isochronous channels and
+		bandwidth at the IRM that were marked for kernel-assisted
+		re- and deallocation.

+Rationale
+=========
+
+How significant is the cache maintenance overhead?
+It depends. Fast eMMC and multiple cache levels with speculative cache
+pre-fetch makes the cache overhead relatively significant. If the DMA
+preparations for the next request are done in parallel with the current
+transfer, the DMA preparation overhead would not affect the MMC performance.
+The intention of non-blocking (asynchronous) MMC requests is to minimize the
+time between when an MMC request ends and another MMC request begins.
+Using mmc_wait_for_req(), the MMC controller is idle while dma_map_sg and
+dma_unmap_sg are processing. Using non-blocking MMC requests makes it
+possible to prepare the caches for next job in parallel with an active
+MMC request.
+
+MMC block driver
+================
+
+The mmc_blk_issue_rw_rq() in the MMC block driver is made non-blocking.
+The increase in throughput is proportional to the time it takes to
+prepare (major part of preparations are dma_map_sg() and dma_unmap_sg())
+a request and how fast the memory is. The faster the MMC/SD is the
+more significant the prepare request time becomes. Roughly the expected
+performance gain is 5% for large writes and 10% on large reads on a L2 cache
+platform. In power save mode, when clocks run on a lower frequency, the DMA
+preparation may cost even more. As long as these slower preparations are run
+in parallel with the transfer performance won't be affected.
+
+Details on measurements from IOZone and mmc_test
+================================================
+
+https://wiki.linaro.org/WorkingGroups/Kernel/Specs/StoragePerfMMC-async-req
+
+MMC core API extension
+======================
+
+There is one new public function mmc_start_req().
+It starts a new MMC command request for a host. The function isn't
+truly non-blocking. If there is an ongoing async request it waits
+for completion of that request and starts the new one and returns. It
+doesn't wait for the new request to complete. If there is no ongoing
+request it starts the new request and returns immediately.
+
+MMC host extensions
+===================
+
+There are two optional members in the mmc_host_ops -- pre_req() and
+post_req() -- that the host driver may implement in order to move work
+to before and after the actual mmc_host_ops.request() function is called.
+In the DMA case pre_req() may do dma_map_sg() and prepare the DMA
+descriptor, and post_req() runs the dma_unmap_sg().
+
+Optimize for the first request
+==============================
+
+The first request in a series of requests can't be prepared in parallel
+with the previous transfer, since there is no previous request.
+The argument is_first_req in pre_req() indicates that there is no previous
+request. The host driver may optimize for this scenario to minimize
+the performance loss. A way to optimize for this is to split the current
+request in two chunks, prepare the first chunk and start the request,
+and finally prepare the second chunk and start the transfer.
+
+Pseudocode to handle is_first_req scenario with minimal prepare overhead:
+
+if (is_first_req && req->size > threshold)
+   /* start MMC transfer for the complete transfer size */
+   mmc_start_command(MMC_CMD_TRANSFER_FULL_SIZE);
+
+   /*
+    * Begin to prepare DMA while cmd is being processed by MMC.
+    * The first chunk of the request should take the same time
+    * to prepare as the "MMC process command time".
+    * If prepare time exceeds MMC cmd time
+    * the transfer is delayed, guesstimate max 4k as first chunk size.
+    */
+    prepare_1st_chunk_for_dma(req);
+    /* flush pending desc to the DMAC (dmaengine.h) */
+    dma_issue_pending(req->dma_desc);
+
+    prepare_2nd_chunk_for_dma(req);
+    /*
+     * The second issue_pending should be called before MMC runs out
+     * of the first chunk. If the MMC runs out of the first data chunk
+     * before this call, the transfer is delayed.
+     */
+    dma_issue_pending(req->dma_desc);

+Netdev features mess and how to get out from it alive
+=====================================================
+
+Author:
+	Michał Mirosław <mirq-linux@rere.qmqm.pl>
+
+
+
+ Part I: Feature sets
+======================
+
+Long gone are the days when a network card would just take and give packets
+verbatim.  Today's devices add multiple features and bugs (read: offloads)
+that relieve an OS of various tasks like generating and checking checksums,
+splitting packets, classifying them.  Those capabilities and their state
+are commonly referred to as netdev features in Linux kernel world.
+
+There are currently three sets of features relevant to the driver, and
+one used internally by network core:
+
+ 1. netdev->hw_features set contains features whose state may possibly
+    be changed (enabled or disabled) for a particular device by user's
+    request.  This set should be initialized in ndo_init callback and not
+    changed later.
+
+ 2. netdev->features set contains features which are currently enabled
+    for a device.  This should be changed only by network core or in
+    error paths of ndo_set_features callback.
+
+ 3. netdev->vlan_features set contains features whose state is inherited
+    by child VLAN devices (limits netdev->features set).  This is currently
+    used for all VLAN devices whether tags are stripped or inserted in
+    hardware or software.
+
+ 4. netdev->wanted_features set contains feature set requested by user.
+    This set is filtered by ndo_fix_features callback whenever it or
+    some device-specific conditions change. This set is internal to
+    networking core and should not be referenced in drivers.
+
+
+
+ Part II: Controlling enabled features
+=======================================
+
+When current feature set (netdev->features) is to be changed, new set
+is calculated and filtered by calling ndo_fix_features callback
+and netdev_fix_features(). If the resulting set differs from current
+set, it is passed to ndo_set_features callback and (if the callback
+returns success) replaces value stored in netdev->features.
+NETDEV_FEAT_CHANGE notification is issued after that whenever current
+set might have changed.
+
+The following events trigger recalculation:
+ 1. device's registration, after ndo_init returned success
+ 2. user requested changes in features state
+ 3. netdev_update_features() is called
+
+ndo_*_features callbacks are called with rtnl_lock held. Missing callbacks
+are treated as always returning success.
+
+A driver that wants to trigger recalculation must do so by calling
+netdev_update_features() while holding rtnl_lock. This should not be done
+from ndo_*_features callbacks. netdev->features should not be modified by
+driver except by means of ndo_fix_features callback.
+
+
+
+ Part III: Implementation hints
+================================
+
+ * ndo_fix_features:
+
+All dependencies between features should be resolved here. The resulting
+set can be reduced further by networking core imposed limitations (as coded
+in netdev_fix_features()). For this reason it is safer to disable a feature
+when its dependencies are not met instead of forcing the dependency on.
+
+This callback should not modify hardware nor driver state (should be
+stateless).  It can be called multiple times between successive
+ndo_set_features calls.
+
+Callback must not alter features contained in NETIF_F_SOFT_FEATURES or
+NETIF_F_NEVER_CHANGE sets. The exception is NETIF_F_VLAN_CHALLENGED but
+care must be taken as the change won't affect already configured VLANs.
+
+ * ndo_set_features:
+
+Hardware should be reconfigured to match passed feature set. The set
+should not be altered unless some error condition happens that can't
+be reliably detected in ndo_fix_features. In this case, the callback
+should update netdev->features to match resulting hardware state.
+Errors returned are not (and cannot be) propagated anywhere except dmesg.
+(Note: successful return is zero, >0 means silent error.)
+
+
+
+ Part IV: Features
+===================
+
+For current list of features, see include/linux/netdev_features.h.
+This section describes semantics of some of them.
+
+ * Transmit checksumming
+
+For complete description, see comments near the top of include/linux/skbuff.h.
+
+Note: NETIF_F_HW_CSUM is a superset of NETIF_F_IP_CSUM + NETIF_F_IPV6_CSUM.
+It means that device can fill TCP/UDP-like checksum anywhere in the packets
+whatever headers there might be.
+
+ * Transmit TCP segmentation offload
+
+NETIF_F_TSO_ECN means that hardware can properly split packets with CWR bit
+set, be it TCPv4 (when NETIF_F_TSO is enabled) or TCPv6 (NETIF_F_TSO6).
+
+ * Transmit DMA from high memory
+
+On platforms where this is relevant, NETIF_F_HIGHDMA signals that
+ndo_start_xmit can handle skbs with frags in high memory.
+
+ * Transmit scatter-gather
+
+Those features say that ndo_start_xmit can handle fragmented skbs:
+NETIF_F_SG --- paged skbs (skb_shinfo()->frags), NETIF_F_FRAGLIST ---
+chained skbs (skb->next/prev list).
+
+ * Software features
+
+Features contained in NETIF_F_SOFT_FEATURES are features of networking
+stack. Driver should not change behaviour based on them.
+
+ * LLTX driver (deprecated for hardware drivers)
+
+NETIF_F_LLTX should be set in drivers that implement their own locking in
+transmit path or don't need locking at all (e.g. software tunnels).
+In ndo_start_xmit, it is recommended to use a try_lock and return
+NETDEV_TX_LOCKED when the spin lock fails.  The locking should also properly
+protect against other callbacks (the rules you need to find out).
+
+Don't use it for new drivers.
+
+ * netns-local device
+
+NETIF_F_NETNS_LOCAL is set for devices that are not allowed to move between
+network namespaces (e.g. loopback).
+
+Don't use it in drivers.
+
+ * VLAN challenged
+
+NETIF_F_VLAN_CHALLENGED should be set for devices which can't cope with VLAN
+headers. Some drivers set this because the cards can't handle the bigger MTU.
+[FIXME: Those cases could be fixed in VLAN code by allowing only reduced-MTU
+VLANs. This may be not useful, though.]

+Linux NFC subsystem
+===================
+
+The Near Field Communication (NFC) subsystem is required to standardize the
+NFC device drivers development and to create an unified userspace interface.
+
+This document covers the architecture overview, the device driver interface
+description and the userspace interface description.
+
+Architecture overview
+---------------------
+
+The NFC subsystem is responsible for:
+      - NFC adapters management;
+      - Polling for targets;
+      - Low-level data exchange;
+
+The subsystem is divided in some parts. The 'core' is responsible for
+providing the device driver interface. On the other side, it is also
+responsible for providing an interface to control operations and low-level
+data exchange.
+
+The control operations are available to userspace via generic netlink.
+
+The low-level data exchange interface is provided by the new socket family
+PF_NFC. The NFC_SOCKPROTO_RAW performs raw communication with NFC targets.
+
+
+             +--------------------------------------+

+                                    +-----------+
+
+Device Driver Interface
+-----------------------
+
+When registering on the NFC subsystem, the device driver must inform the core
+of the set of supported NFC protocols and the set of ops callbacks. The ops
+callbacks that must be implemented are the following:
+
+* start_poll - setup the device to poll for targets
+* stop_poll - stop on progress polling operation
+* activate_target - select and initialize one of the targets found
+* deactivate_target - deselect and deinitialize the selected target
+* data_exchange - send data and receive the response (transceive operation)
+
+Userspace interface
+--------------------
+
+The userspace interface is divided in control operations and low-level data
+exchange operation.
+
+CONTROL OPERATIONS:
+
+Generic netlink is used to implement the interface to the control operations.
+The operations are composed by commands and events, all listed below:
+
+* NFC_CMD_GET_DEVICE - get specific device info or dump the device list
+* NFC_CMD_START_POLL - setup a specific device to polling for targets
+* NFC_CMD_STOP_POLL - stop the polling operation in a specific device
+* NFC_CMD_GET_TARGET - dump the list of targets found by a specific device
+
+* NFC_EVENT_DEVICE_ADDED - reports an NFC device addition
+* NFC_EVENT_DEVICE_REMOVED - reports an NFC device removal
+* NFC_EVENT_TARGETS_FOUND - reports START_POLL results when 1 or more targets
+are found
+
+The user must call START_POLL to poll for NFC targets, passing the desired NFC
+protocols through NFC_ATTR_PROTOCOLS attribute. The device remains in polling
+state until it finds any target. However, the user can stop the polling
+operation by calling STOP_POLL command. In this case, it will be checked if
+the requester of STOP_POLL is the same of START_POLL.
+
+If the polling operation finds one or more targets, the event TARGETS_FOUND is
+sent (including the device id). The user must call GET_TARGET to get the list of
+all targets found by such device. Each reply message has target attributes with
+relevant information such as the supported NFC protocols.
+
+All polling operations requested through one netlink socket are stopped when
+it's closed.
+
+LOW-LEVEL DATA EXCHANGE:
+
+The userspace must use PF_NFC sockets to perform any data communication with
+targets. All NFC sockets use AF_NFC:
+
+struct sockaddr_nfc {
+       sa_family_t sa_family;
+       __u32 dev_idx;
+       __u32 target_idx;
+       __u32 nfc_protocol;
+};
+
+To establish a connection with one target, the user must create an
+NFC_SOCKPROTO_RAW socket and call the 'connect' syscall with the sockaddr_nfc
+struct correctly filled. All information comes from NFC_EVENT_TARGETS_FOUND
+netlink event. As a target can support more than one NFC protocol, the user
+must inform which protocol it wants to use.
+
+Internally, 'connect' will result in an activate_target call to the driver.
+When the socket is closed, the target is deactivated.
+
+The data format exchanged through the sockets is NFC protocol dependent. For
+instance, when communicating with MIFARE tags, the data exchanged are MIFARE
+commands and their responses.
+
+The first received package is the response to the first sent package and so
+on. In order to allow valid "empty" responses, every data received has a NULL
+header of 1 byte.

+Support for power domains is provided through the pm_domain field of struct
+device.  This field is a pointer to an object of type struct dev_pm_domain,
 defined in include/linux/pm.h, providing a set of power management callbacks
 analogous to the subsystem-level and device driver callbacks that are executed
-for the given device during all power transitions, in addition to the respective
-subsystem-level callbacks.  Specifically, the power domain "suspend" callbacks
-(i.e. ->runtime_suspend(), ->suspend(), ->freeze(), ->poweroff(), etc.) are
-executed after the analogous subsystem-level callbacks, while the power domain
-"resume" callbacks (i.e. ->runtime_resume(), ->resume(), ->thaw(), ->restore,

-returned by the "suspend" and "resume" power domain callbacks are ignored.
-
-Power domain ->runtime_idle() callback is executed before the subsystem-level
-->runtime_idle() callback and the result returned by it is not ignored.  Namely,
-if it returns error code, the subsystem-level ->runtime_idle() callback will not
-be called and the helper function rpm_idle() executing it will return error
-code.  This mechanism is intended to help platforms where saving device state
-is a time consuming operation and should only be carried out if all devices

-Namely, the power domain ->runtime_idle() callback may return error code until

-all devices in the power domain (it is recommended that the returned error code
-be -EBUSY in those cases), preventing the subsystem-level ->runtime_idle()

-System Devices
---------------
-System devices (sysdevs) follow a slightly different API, which can be found in
-
-	include/linux/sysdev.h
-	drivers/base/sys.c
-
-System devices will be suspended with interrupts disabled, and after all other
-devices have been suspended.  On resume, they will be resumed before any other
-devices, and also with interrupts disabled.  These things occur in special
-"sysdev_driver" phases, which affect only system devices.
-
-Thus, after the suspend_noirq (or freeze_noirq or poweroff_noirq) phase, when
-the non-boot CPUs are all offline and IRQs are disabled on the remaining online
-CPU, then a sysdev_driver.suspend phase is carried out, and the system enters a
-sleep state (or a system image is created).  During resume (or after the image
-has been created or loaded) a sysdev_driver.resume phase is carried out, IRQs
-are enabled on the only online CPU, the non-boot CPUs are enabled, and the
-resume_noirq (or thaw_noirq or restore_noirq) phase begins.
-
-Code to actually enter and exit the system-wide low power state sometimes
-involves hardware details that are only known to the boot firmware, and
-may leave a CPU running software (from SRAM or flash memory) that monitors
-the system and manages its wakeup sequence.
+for the given device during all power transitions, instead of the respective
+subsystem-level callbacks.  Specifically, if a device's pm_domain pointer is
+not NULL, the ->suspend() callback from the object pointed to by it will be
+executed instead of its subsystem's (e.g. bus type's) ->suspend() callback and
+anlogously for all of the remaining callbacks.  In other words, power management
+domain callbacks, if defined for the given device, always take precedence over
+the callbacks provided by the device's subsystem (e.g. bus type).

+	 * used, distinct from short branches.
+	 *
+	 * Current:
+	 *
+	 * For now, both branch types assemble to 2 words (short branches padded
+	 * with a NOP); this is less efficient, but assembly will always complete
+	 * after exactly 3 passes:
+	 *
+	 * First pass: No code buffer; Program is "faux-generated" -- no code
+	 * emitted but maximum size of output determined (and addrs[] filled
+	 * in).	 Also, we note whether we use M[], whether we use skb data, etc.
+	 * All generation choices assumed to be 'worst-case', e.g. branches all
+	 * far (2 instructions), return path code reduction not available, etc.
+	 *
+	 * Second pass: Code buffer allocated with size determined previously.
+	 * Prologue generated to support features we have seen used.  Exit paths
+	 * determined and addrs[] is filled in again, as code may be slightly
+	 * smaller as a result.
+	 *
+	 * Third pass: Code generated 'for real', and branch destinations
+	 * determined from now-accurate addrs[] map.
+	 *
+	 * Ideal:
+	 *
+	 * If we optimise this, near branches will be shorter.	On the
+	 * first assembly pass, we should err on the side of caution and
+	 * generate the biggest code.  On subsequent passes, branches will be
+	 * generated short or long and code size will reduce.  With smaller
+	 * code, more branches may fall into the short category, and code will
+	 * reduce more.
+	 *
+	 * Finally, if we see one pass generate code the same size as the
+	 * previous pass we have converged and should now generate code for
+	 * real.  Allocating at the end will also save the memory that would
+	 * otherwise be wasted by the (small) current code shrinkage.
+	 * Preferably, we should do a small number of passes (e.g. 5) and if we
+	 * haven't converged by then, get impatient and force code to generate
+	 * as-is, even if the odd branch would be left long.  The chances of a
+	 * long jump are tiny with all but the most enormous of BPF filter
+	 * inputs, so we should usually converge on the third pass.

- * Our hypercalls mechanism used to be based on direct software interrupts.
- * After Anthony's "Refactor hypercall infrastructure" kvm patch, we decided to

- *
- * KVM_HYPERCALL is actually a "vmcall" instruction, which generates an invalid
- * opcode fault (fault 6) on non-VT cpus, so the easiest solution seemed to be
- * an *emulation approach*: if the fault was really produced by an hypercall
- * (is_hypercall() does exactly this check), we can just call the corresponding
- * hypercall host implementation function.

- * So we implemented the *patching (or rewriting) approach*: every time we hit
- * the KVM_HYPERCALL opcode in Guest code, we patch it to the old "int 0x1f"
- * opcode, so next time the Guest calls this hypercall it will use the
- * faster trap mechanism.
- *
- * Matias even benchmarked it to convince you: this shows the average cycle

- * made 5 runs of the benchmark:

-/* Autogain + exposure algorithm for cameras with a coarse exposure control
-   (usually this means we can only control the clockdiv to change exposure)
-   As changing the clockdiv so that the fps drops from 30 to 15 fps for
-   example, will lead to a huge exposure change (it effectively doubles),
-   this algorithm normally tries to only adjust the gain (between 40 and
-   80 %) and if that does not help, only then changes exposure. This leads
-   to a much more stable image then using the knee algorithm which at
-   certain points of the knee graph will only try to adjust exposure,
-   which leads to oscilating as one exposure step is huge.
-
-   Note this assumes that the sd struct for the cam in question has
-   exp_too_high_cnt and exp_too_high_cnt int members for use by this function.
-
-   Returns 0 if no changes were made, 1 if the gain and or exposure settings

-/* Okay, this is some magic that I worked out and the reasoning behind it...
-
-   The biggest problem with any USB device is of course: "what to do
-   when the user unplugs the device while it is in use by an application?"
-   We have several options:
-   1) Curse them with the 7 plagues when they do (requires divine intervention)
-   2) Tell them not to (won't work: they'll do it anyway)
-   3) Oops the kernel (this will have a negative effect on a user's uptime)
-   4) Do something sensible.
-
-   Of course, we go for option 4.
-
-   It happens that this device will be linked to two times, once from
-   usb_device and once from the video_device in their respective 'private'
-   pointers. This is done when the device is probed() and all initialization
-   succeeded. The pwc_device struct links back to both structures.
-
-   When a device is unplugged while in use it will be removed from the
-   list of known USB devices; I also de-register it as a V4L device, but
-   unfortunately I can't free the memory since the struct is still in use
-   by the file descriptor. This free-ing is then deferend until the first
-   opportunity. Crude, but it works.
-
-   A small 'advantage' is that if a user unplugs the cam and plugs it back
-   in, it should get assigned the same video device minor, but unfortunately
-   it's non-trivial to re-link the cam back to the video device... (that
-   would surely be magic! :))

+ * Since the ilt for the function that is down is not valid, this will cause
+ * a translation error which is unrecoverable.
+ * The Workaround is intended to make sure that when this happens nothing fatal
+ * will occur. The workaround:
+ *	1.  First PF driver which loads on a path will:
+ *		a.  After taking the chip out of reset, by using pretend,
+ *		    it will write "0" to the following registers of
+ *		    the other vnics.

+ *		    REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);

+ *		    And for itself it will write '1' to
+ *		    PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
+ *		    dmae-operations (writing to pram for example.)
+ *		    note: can be done for only function 6,7 but cleaner this
+ *			  way.
+ *		b.  Write zero+valid to the entire ILT.
+ *		c.  Init the first_timers_ilt_entry, last_timers_ilt_entry of
+ *		    VNIC3 (of that port). The range allocated will be the
+ *		    entire ILT. This is needed to prevent  ILT range error.
+ *	2.  Any PF driver load flow:
+ *		a.  ILT update with the physical addresses of the allocated
+ *		    logical pages.
+ *		b.  Wait 20msec. - note that this timeout is needed to make
+ *		    sure there are no requests in one of the PXP internal
+ *		    queues with "old" ILT addresses.
+ *		c.  PF enable in the PGLC.
+ *		d.  Clear the was_error of the PF in the PGLC. (could have
+ *		    occured while driver was down)
+ *		e.  PF enable in the CFC (WEAK + STRONG)
+ *		f.  Timers scan enable
+ *	3.  PF driver unload flow:
+ *		a.  Clear the Timers scan_en.
+ *		b.  Polling for scan_on=0 for that PF.
+ *		c.  Clear the PF enable bit in the PXP.
+ *		d.  Clear the PF enable in the CFC (WEAK + STRONG)
+ *		e.  Write zero+valid to all ILT entries (The valid bit must
+ *		    stay set)
+ *		f.  If this is VNIC 3 of a port then also init
+ *		    first_timers_ilt_entry to zero and last_timers_ilt_entry
+ *		    to the last enrty in the ILT.
+ *
+ *	Notes:
+ *	Currently the PF error in the PGLC is non recoverable.
+ *	In the future the there will be a recovery routine for this error.
+ *	Currently attention is masked.
+ *	Having an MCP lock on the load/unload process does not guarantee that
+ *	there is no Timer disable during Func6/7 enable. This is because the
+ *	Timers scan is currently being cleared by the MCP on FLR.
+ *	Step 2.d can be done only for PF6/7 and the driver can also check if
+ *	there is error before clearing it. But the flow above is simpler and
+ *	more general.
+ *	All ILT entries are written by zero+valid and not just PF6/7
+ *	ILT entries since in the future the ILT entries allocation for
+ *	PF-s might be dynamic.

  * NAPI and NETPOLL support
  * (C) 2004 by Eric Lemoine (eric.lemoine@gmail.com)
  *
- * TODO:
- *  - Now that the driver was significantly simplified, I need to rework
- *    the locking. I'm sure we don't need _2_ spinlocks, and we probably
- *    can avoid taking most of them for so long period of time (and schedule
- *    instead). The main issues at this point are caused by the netdev layer
- *    though:
- *
- *    gem_change_mtu() and gem_set_multicast() are called with a read_lock()
- *    help by net/core/dev.c, thus they can't schedule. That means they can't
- *    call napi_disable() neither, thus force gem_poll() to keep a spinlock
- *    where it could have been dropped. change_mtu especially would love also to
- *    be able to msleep instead of horrid locked delays when resetting the HW,
- *    but that read_lock() makes it impossible, unless I defer it's action to
- *    the reset task, which means it'll be asynchronous (won't take effect until
- *    the system schedules a bit).
- *
- *    Also, it would probably be possible to also remove most of the long-life
- *    locking in open/resume code path (gem_reinit_chip) by beeing more careful
- *    about when we can start taking interrupts or get xmit() called...

+
+	  The "hide" parameter (only applicable if backend driver is compiled

+

+/******************************************************************************
+ * Xen selfballoon driver (and optional frontswap self-shrinking driver)
+ *
+ * Copyright (c) 2009-2011, Dan Magenheimer, Oracle Corp.
+ *
+ * This code complements the cleancache and frontswap patchsets to optimize
+ * support for Xen Transcendent Memory ("tmem").  The policy it implements
+ * is rudimentary and will likely improve over time, but it does work well
+ * enough today.
+ *
+ * Two functionalities are implemented here which both use "control theory"
+ * (feedback) to optimize memory utilization. In a virtualized environment
+ * such as Xen, RAM is often a scarce resource and we would like to ensure
+ * that each of a possibly large number of virtual machines is using RAM
+ * efficiently, i.e. using as little as possible when under light load
+ * and obtaining as much as possible when memory demands are high.
+ * Since RAM needs vary highly dynamically and sometimes dramatically,
+ * "hysteresis" is used, that is, memory target is determined not just
+ * on current data but also on past data stored in the system.
+ *
+ * "Selfballooning" creates memory pressure by managing the Xen balloon
+ * driver to decrease and increase available kernel memory, driven
+ * largely by the target value of "Committed_AS" (see /proc/meminfo).
+ * Since Committed_AS does not account for clean mapped pages (i.e. pages
+ * in RAM that are identical to pages on disk), selfballooning has the
+ * affect of pushing less frequently used clean pagecache pages out of
+ * kernel RAM and, presumably using cleancache, into Xen tmem where
+ * Xen can more efficiently optimize RAM utilization for such pages.
+ *
+ * When kernel memory demand unexpectedly increases faster than Xen, via
+ * the selfballoon driver, is able to (or chooses to) provide usable RAM,
+ * the kernel may invoke swapping.  In most cases, frontswap is able
+ * to absorb this swapping into Xen tmem.  However, due to the fact
+ * that the kernel swap subsystem assumes swapping occurs to a disk,
+ * swapped pages may sit on the disk for a very long time; even if
+ * the kernel knows the page will never be used again.  This is because
+ * the disk space costs very little and can be overwritten when
+ * necessary.  When such stale pages are in frontswap, however, they
+ * are taking up valuable real estate.  "Frontswap selfshrinking" works
+ * to resolve this:  When frontswap activity is otherwise stable
+ * and the guest kernel is not under memory pressure, the "frontswap
+ * selfshrinking" accounts for this by providing pressure to remove some
+ * pages from frontswap and return them to kernel memory.
+ *
+ * For both "selfballooning" and "frontswap-selfshrinking", a worker
+ * thread is used and sysfs tunables are provided to adjust the frequency
+ * and rate of adjustments to achieve the goal, as well as to disable one
+ * or both functions independently.
+ *
+ * While some argue that this functionality can and should be implemented
+ * in userspace, it has been observed that bad things happen (e.g. OOMs).
+ *
+ * System configuration note: Selfballooning should not be enabled on
+ * systems without a sufficiently large swap device configured; for best
+ * results, it is recommended that total swap be increased by the size
+ * of the guest memory.  Also, while technically not required to be
+ * configured, it is highly recommended that frontswap also be configured
+ * and enabled when selfballooning is running.  So, selfballooning
+ * is disabled by default if frontswap is not configured and can only
+ * be enabled with the "selfballooning" kernel boot option; similarly
+ * selfballooning is enabled by default if frontswap is configured and
+ * can be disabled with the "noselfballooning" kernel boot option.  Finally,
+ * when frontswap is configured, frontswap-selfshrinking can be disabled
+ * with the "noselfshrink" kernel boot option.
+ *
+ * Selfballooning is disallowed in domain0 and force-disabled.

+	 * we will use, so we need the truncate reservation to be seperate so it
+	 * doesn't end up using space reserved for updating the inode or
+	 * removing the orphan item.  We also need to be able to stop the
+	 * transaction and start a new one, which means we need to be able to
+	 * update the inode several times, and we have no idea of knowing how
+	 * many times that will be, so we can't just reserve 1 item for the
+	 * entirety of the opration, so that has to be done seperately as well.
+	 * Then there is the orphan item, which does indeed need to be held on
+	 * to for the whole operation, and we need nobody to touch this reserved
+	 * space except the orphan code.
+	 *
+	 * So that leaves us with
+	 *
+	 * 1) root->orphan_block_rsv - for the orphan deletion.

-	 * other half not, but this is possible in our 'failure mode emulation'
-	 * infrastructure at least.
-	 *
-	 * So what is the problem, why we need to drop those nodes? Whey can't
-	 * we just clean-up the second half of B by putting a padding node

-	 * only about the GC head, so we could do this trick only if the bud
-	 * belongs to the GC head, but it does not seem to be worth an
-	 * additional "if" statement.
-	 *
-	 * So, imagine the file-system is full, we run GC which is moving valid
-	 * nodes from LEB X to LEB Y (obviously, LEB Y is the current GC head
-	 * LEB). The @c->gc_lnum is -1, which means that GC will retain LEB X
-	 * and will try to continue. Imagine that LEB X is currently the
-	 * dirtiest LEB, and the amount of used space in LEB Y is exactly the
-	 * same as amount of free space in LEB X.
-	 *
-	 * And a power cut happens when nodes are moved from LEB X to LEB Y. We
-	 * are here trying to recover LEB Y which is the GC head LEB. We find
-	 * the min. I/O unit B as described above. Then we clean-up LEB Y by
-	 * padding min. I/O unit. And later 'ubifs_rcvry_gc_commit()' function
-	 * fails, because it cannot find a dirty LEB which could be GC'd into
-	 * LEB Y! Even LEB X does not match because the amount of valid nodes
-	 * there does not fit the free space in LEB Y any more! And this is
-	 * because of the padding node which we added to LEB Y. The
-	 * user-visible effect of this which I once observed and analysed is
-	 * that we cannot mount the file-system with -ENOSPC error.
-	 *
-	 * So obviously, to make sure that situation does not happen we should
