+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add a duplicate irq range with an offset on the hwirq's so the
+driver can detect that enable_fiq() is used.
+Tested with downstream dwc_otg USB controller driver.

+Subject: [PATCH 010/454] irq_bcm2836: Send event when onlining sleeping cores
+
+In order to reduce power consumption and bus traffic, it is sensible
+for secondary cores to enter a low-power idle state when waiting to
+be started. The wfe instruction causes a core to wait until an event
+or interrupt arrives before continuing to the next instruction.
+The sev instruction sends a wakeup event to the other cores, so call
+it from bcm2836_smp_boot_secondary, the function that wakes up the
+waiting cores during booting.
+
+It is harmless to use this patch without the corresponding change
+adding wfe to the ARMv7/ARMv8-32 stubs, but if the stubs are updated
+and this patch is not applied then the other cores will sleep forever.
+

+Subject: [PATCH 012/454] spi-bcm2835: Support pin groups other than 7-11
+
+The spi-bcm2835 driver automatically uses GPIO chip-selects due to
+some unreliability of the native ones. In doing so it chooses the
+same pins as the native chip-selects would use, but the existing
+code always uses pins 7 and 8, wherever the SPI function is mapped.
+
+Search the pinctrl group assigned to the driver for pins that
+correspond to native chip-selects, and use those for GPIO chip-
+selects.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The Raspberry Pi firmware looks at the RSTS register to know which
+partition to boot from. The reboot syscall command
+LINUX_REBOOT_CMD_RESTART2 supports passing in a string argument.
+
+Add support for passing in a partition number 0..63 to boot from.
+Partition 63 is a special partiton indicating halt.
+If the partition doesn't exist, the firmware falls back to partition 0.

+The claim-clocks property can be used to prevent PLLs and dividers

+Subject: [PATCH 028/454] clk-bcm2835: Read max core clock from firmware
+
+The VPU is responsible for managing the core clock, usually under
+direction from the bcm2835-cpufreq driver but not via the clk-bcm2835
+driver. Since the core frequency can change without warning, it is
+safer to report the maximum clock rate to users of the core clock -
+I2C, SPI and the mini UART - to err on the safe side when calculating
+clock divisors.
+
+If the DT node for the clock driver includes a reference to the
+firmware node, use the firmware API to query the maximum core clock
+instead of reading the divider registers.
+
+Prior to this patch, a "100KHz" I2C bus was sometimes clocked at about
+160KHz. In particular, switching to the 4.9 kernel was likely to break
+SenseHAT usage on a Pi3.

+Subject: [PATCH 031/454] Update vfpmodule.c
+
+Christopher Alexander Tobias Schulze - May 2, 2015, 11:57 a.m.
+This patch fixes a problem with VFP state save and restore related
+to exception handling (panic with message "BUG: unsupported FP
+instruction in kernel mode") present on VFP11 floating point units
+(as used with ARM1176JZF-S CPUs, e.g. on first generation Raspberry
+Pi boards). This patch was developed and discussed on
+
+ https://github.com/raspberrypi/linux/issues/859
+
+A precondition to see the crashes is that floating point exception
+traps are enabled. In this case, the VFP11 might determine that a FPU
+operation needs to trap at a point in time when it is not possible to
+signal this to the ARM11 core any more. The VFP11 will then set the
+FPEXC.EX bit and store the trapped opcode in FPINST. (In some cases,
+a second opcode might have been accepted by the VFP11 before the
+exception was detected and could be reported to the ARM11 - in this
+case, the VFP11 also sets FPEXC.FP2V and stores the second opcode in
+FPINST2.)
+
+If FPEXC.EX is set, the VFP11 will "bounce" the next FPU opcode issued
+by the ARM11 CPU, which will be seen by the ARM11 as an undefined opcode
+trap. The VFP support code examines the FPEXC.EX and FPEXC.FP2V bits
+to decide what actions to take, i.e., whether to emulate the opcodes
+found in FPINST and FPINST2, and whether to retry the bounced instruction.
+
+If a user space application has left the VFP11 in this "pending trap"
+state, the next FPU opcode issued to the VFP11 might actually be the
+VSTMIA operation vfp_save_state() uses to store the FPU registers
+to memory (in our test cases, when building the signal stack frame).
+In this case, the kernel crashes as described above.
+
+This patch fixes the problem by making sure that vfp_save_state() is
+always entered with FPEXC.EX cleared. (The current value of FPEXC has
+already been saved, so this does not corrupt the context. Clearing
+FPEXC.EX has no effects on FPINST or FPINST2. Also note that many
+callers already modify FPEXC by setting FPEXC.EN before invoking
+vfp_save_state().)
+
+This patch also addresses a second problem related to FPEXC.EX: After
+returning from signal handling, the kernel reloads the VFP context
+from the user mode stack. However, the current code explicitly clears
+both FPEXC.EX and FPEXC.FP2V during reload. As VFP11 requires these
+bits to be preserved, this patch disables clearing them for VFP
+implementations belonging to architecture 1. There should be no
+negative side effects: the user can set both bits by executing FPU
+opcodes anyway, and while user code may now place arbitrary values
+into FPINST and FPINST2 (e.g., non-VFP ARM opcodes) the VFP support
+code knows which instructions can be emulated, and rejects other
+opcodes with "unhandled bounce" messages, so there should be no
+security impact from allowing reloading FPEXC.EX and FPEXC.FP2V.

+
+Add FIQ patch to dwc_otg driver. Enable with dwc_otg.fiq_fix_enable=1. Should give about 10% more ARM performance.
+Thanks to Gordon and Costas
+
+Avoid dynamic memory allocation for channel lock in USB driver. Thanks ddv2005.
+
+Add NAK holdoff scheme. Enabled by default, disable with dwc_otg.nak_holdoff_enable=0. Thanks gsh
+
+Make sure we wait for the reset to finish
+
+dwc_otg: fix bug in dwc_otg_hcd.c resulting in silent kernel
+ memory corruption, escalating to OOPS under high USB load.
+
+dwc_otg: Fix unsafe access of QTD during URB enqueue
+
+In dwc_otg_hcd_urb_enqueue during qtd creation, it was possible that the
+transaction could complete almost immediately after the qtd was assigned
+to a host channel during URB enqueue, which meant the qtd pointer was no
+longer valid having been completed and removed. Usually, this resulted in
+an OOPS during URB submission. By predetermining whether transactions
+need to be queued or not, this unsafe pointer access is avoided.
+
+This bug was only evident on the Pi model A where a device was attached
+that had no periodic endpoints (e.g. USB pendrive or some wlan devices).
+
+dwc_otg: Fix incorrect URB allocation error handling
+
+If the memory allocation for a dwc_otg_urb failed, the kernel would OOPS
+because for some reason a member of the *unallocated* struct was set to
+zero. Error handling changed to fail correctly.
+
+dwc_otg: fix potential use-after-free case in interrupt handler
+
+If a transaction had previously aborted, certain interrupts are
+enabled to track error counts and reset where necessary. On IN
+endpoints the host generates an ACK interrupt near-simultaneously
+with completion of transfer. In the case where this transfer had
+previously had an error, this results in a use-after-free on
+the QTD memory space with a 1-byte length being overwritten to
+0x00.
+
+dwc_otg: add handling of SPLIT transaction data toggle errors
+
+Previously a data toggle error on packets from a USB1.1 device behind
+a TT would result in the Pi locking up as the driver never handled
+the associated interrupt. Patch adds basic retry mechanism and
+interrupt acknowledgement to cater for either a chance toggle error or
+for devices that have a broken initial toggle state (FT8U232/FT232BM).
+
+dwc_otg: implement tasklet for returning URBs to usbcore hcd layer
+
+The dwc_otg driver interrupt handler for transfer completion will spend
+a very long time with interrupts disabled when a URB is completed -
+this is because usb_hcd_giveback_urb is called from within the handler
+which for a USB device driver with complicated processing (e.g. webcam)
+will take an exorbitant amount of time to complete. This results in
+missed completion interrupts for other USB packets which lead to them
+being dropped due to microframe overruns.
+
+This patch splits returning the URB to the usb hcd layer into a
+high-priority tasklet. This will have most benefit for isochronous IN
+transfers but will also have incidental benefit where multiple periodic
+devices are active at once.
+
+dwc_otg: fix NAK holdoff and allow on split transactions only
+
+This corrects a bug where if a single active non-periodic endpoint
+had at least one transaction in its qh, on frnum == MAX_FRNUM the qh
+would get skipped and never get queued again. This would result in
+a silent device until error detection (automatic or otherwise) would
+either reset the device or flush and requeue the URBs.
+
+Additionally the NAK holdoff was enabled for all transactions - this
+would potentially stall a HS endpoint for 1ms if a previous error state
+enabled this interrupt and the next response was a NAK. Fix so that
+only split transactions get held off.
+
+dwc_otg: Call usb_hcd_unlink_urb_from_ep with lock held in completion handler
+
+usb_hcd_unlink_urb_from_ep must be called with the HCD lock held. Calling it
+asynchronously in the tasklet was not safe (regression in
+c4564d4a1a0a9b10d4419e48239f5d99e88d2667).
+
+This change unlinks it from the endpoint prior to queueing it for handling in
+the tasklet, and also adds a check to ensure the urb is OK to be unlinked
+before doing so.
+
+NULL pointer dereference kernel oopses had been observed in usb_hcd_giveback_urb
+when a USB device was unplugged/replugged during data transfer. This effect
+was reproduced using automated USB port power control, hundreds of replug
+events were performed during active transfers to confirm that the problem was
+eliminated.
+
+USB fix using a FIQ to implement split transactions
+
+This commit adds a FIQ implementaion that schedules
+the split transactions using a FIQ so we don't get
+held off by the interrupt latency of Linux
+
+dwc_otg: fix device attributes and avoid kernel warnings on boot
+
+dcw_otg: avoid logging function that can cause panics
+
+See: https://github.com/raspberrypi/firmware/issues/21
+Thanks to cleverca22 for fix
+
+dwc_otg: mask correct interrupts after transaction error recovery
+
+The dwc_otg driver will unmask certain interrupts on a transaction
+that previously halted in the error state in order to reset the
+QTD error count. The various fine-grained interrupt handlers do not
+consider that other interrupts besides themselves were unmasked.
+
+By disabling the two other interrupts only ever enabled in DMA mode
+for this purpose, we can avoid unnecessary function calls in the
+IRQ handler. This will also prevent an unneccesary FIQ interrupt
+from being generated if the FIQ is enabled.
+
+dwc_otg: fiq: prevent FIQ thrash and incorrect state passing to IRQ
+
+In the case of a transaction to a device that had previously aborted
+due to an error, several interrupts are enabled to reset the error
+count when a device responds. This has the side-effect of making the
+FIQ thrash because the hardware will generate multiple instances of
+a NAK on an IN bulk/interrupt endpoint and multiple instances of ACK
+on an OUT bulk/interrupt endpoint. Make the FIQ mask and clear the
+associated interrupts.
+
+Additionally, on non-split transactions make sure that only unmasked
+interrupts are cleared. This caused a hard-to-trigger but serious
+race condition when you had the combination of an endpoint awaiting
+error recovery and a transaction completed on an endpoint - due to
+the sequencing and timing of interrupts generated by the dwc_otg core,
+it was possible to confuse the IRQ handler.
+
+Fix function tracing

+dwc_otg: prevent OOPSes during device disconnects
+
+The dwc_otg_urb_enqueue function is thread-unsafe. In particular the
+access of urb->hcpriv, usb_hcd_link_urb_to_ep, dwc_otg_urb->qtd and
+friends does not occur within a critical section and so if a device
+was unplugged during activity there was a high chance that the
+usbcore hub_thread would try to disable the endpoint with partially-
+formed entries in the URB queue. This would result in BUG() or null
+pointer dereferences.
+
+Fix so that access of urb->hcpriv, enqueuing to the hardware and
+adding to usbcore endpoint URB lists is contained within a single
+critical section.
+
+dwc_otg: prevent BUG() in TT allocation if hub address is > 16
+
+A fixed-size array is used to track TT allocation. This was
+previously set to 16 which caused a crash because
+dwc_otg_hcd_allocate_port would read past the end of the array.
+
+This was hit if a hub was plugged in which enumerated as addr > 16,
+due to previous device resets or unplugs.
+
+Also add #ifdef FIQ_DEBUG around hcd->hub_port_alloc[], which grows
+to a large size if 128 hub addresses are supported. This field is
+for debug only for tracking which frame an allocate happened in.
+
+dwc_otg: make channel halts with unknown state less damaging
+
+If the IRQ received a channel halt interrupt through the FIQ
+with no other bits set, the IRQ would not release the host
+channel and never complete the URB.
+
+Add catchall handling to treat as a transaction error and retry.
+
+dwc_otg: fiq_split: use TTs with more granularity
+
+This fixes certain issues with split transaction scheduling.
+
+- Isochronous multi-packet OUT transactions now hog the TT until
+ they are completed - this prevents hubs aborting transactions
+ if they get a periodic start-split out-of-order
+- Don't perform TT allocation on non-periodic endpoints - this
+ allows simultaneous use of the TT's bulk/control and periodic
+ transaction buffers
+
+This commit will mainly affect USB audio playback.
+
+dwc_otg: fix potential sleep while atomic during urb enqueue
+
+Fixes a regression introduced with eb1b482a. Kmalloc called from
+dwc_otg_hcd_qtd_add / dwc_otg_hcd_qtd_create did not always have
+the GPF_ATOMIC flag set. Force this flag when inside the larger
+critical section.
+
+dwc_otg: make fiq_split_enable imply fiq_fix_enable
+
+Failing to set up the FIQ correctly would result in
+"IRQ 32: nobody cared" errors in dmesg.
+
+dwc_otg: prevent crashes on host port disconnects
+
+Fix several issues resulting in crashes or inconsistent state
+if a Model A root port was disconnected.
+
+- Clean up queue heads properly in kill_urbs_in_qh_list by
+ removing the empty QHs from the schedule lists
+- Set the halt status properly to prevent IRQ handlers from
+ using freed memory
+- Add fiq_split related cleanup for saved registers
+- Make microframe scheduling reclaim host channels if
+ active during a disconnect
+- Abort URBs with -ESHUTDOWN status response, informing
+ device drivers so they respond in a more correct fashion
+ and don't try to resubmit URBs
+- Prevent IRQ handlers from attempting to handle channel
+ interrupts if the associated URB was dequeued (and the
+ driver state was cleared)
+
+dwc_otg: prevent leaking URBs during enqueue
+
+A dwc_otg_urb would get leaked if the HCD enqueue function
+failed for any reason. Free the URB at the appropriate points.
+
+dwc_otg: Enable NAK holdoff for control split transactions
+
+Certain low-speed devices take a very long time to complete a
+data or status stage of a control transaction, producing NAK
+responses until they complete internal processing - the USB2.0
+spec limit is up to 500mS. This causes the same type of interrupt
+storm as seen with USB-serial dongles prior to c8edb238.
+
+In certain circumstances, usually while booting, this interrupt
+storm could cause SD card timeouts.
+
+dwc_otg: Fix for occasional lockup on boot when doing a USB reset
+
+dwc_otg: Don't issue traffic to LS devices in FS mode
+
+Issuing low-speed packets when the root port is in full-speed mode
+causes the root port to stop responding. Explicitly fail when
+enqueuing URBs to a LS endpoint on a FS bus.
+
+Fix ARM architecture issue with local_irq_restore()
+
+If local_fiq_enable() is called before a local_irq_restore(flags) where
+the flags variable has the F bit set, the FIQ will be erroneously disabled.
+
+Fixup arch_local_irq_restore to avoid trampling the F bit in CPSR.
+
+Also fix some of the hacks previously implemented for previous dwc_otg
+incarnations.
+
+dwc_otg: fiq_fsm: Base commit for driver rewrite
+
+This commit removes the previous FIQ fixes entirely and adds fiq_fsm.
+
+This rewrite features much more complete support for split transactions
+and takes into account several OTG hardware bugs. High-speed
+isochronous transactions are also capable of being performed by fiq_fsm.
+
+All driver options have been removed and replaced with:
+ - dwc_otg.fiq_enable (bool)
+ - dwc_otg.fiq_fsm_enable (bool)
+ - dwc_otg.fiq_fsm_mask (bitmask)
+ - dwc_otg.nak_holdoff (unsigned int)
+
+Defaults are specified such that fiq_fsm behaves similarly to the
+previously implemented FIQ fixes.
+
+fiq_fsm: Push error recovery into the FIQ when fiq_fsm is used
+
+If the transfer associated with a QTD failed due to a bus error, the HCD
+would retry the transfer up to 3 times (implementing the USB2.0
+three-strikes retry in software).
+
+Due to the masking mechanism used by fiq_fsm, it is only possible to pass
+a single interrupt through to the HCD per-transfer.
+
+In this instance host channels would fall off the radar because the error
+reset would function, but the subsequent channel halt would be lost.
+
+Push the error count reset into the FIQ handler.
+
+fiq_fsm: Implement timeout mechanism
+
+For full-speed endpoints with a large packet size, interrupt latency
+runs the risk of the FIQ starting a transaction too late in a full-speed
+frame. If the device is still transmitting data when EOF2 for the
+downstream frame occurs, the hub will disable the port. This change is
+not reflected in the hub status endpoint and the device becomes
+unresponsive.
+
+Prevent high-bandwidth transactions from being started too late in a
+frame. The mechanism is not guaranteed: a combination of bit stuffing
+and hub latency may still result in a device overrunning.
+
+fiq_fsm: fix bounce buffer utilisation for Isochronous OUT
+
+Multi-packet isochronous OUT transactions were subject to a few bounday
+bugs. Fix them.
+
+Audio playback is now much more robust: however, an issue stands with
+devices that have adaptive sinks - ALSA plays samples too fast.
+
+dwc_otg: Return full-speed frame numbers in HS mode
+
+The frame counter increments on every *microframe* in high-speed mode.
+Most device drivers expect this number to be in full-speed frames - this
+caused considerable confusion to e.g. snd_usb_audio which uses the
+frame counter to estimate the number of samples played.
+
+fiq_fsm: save PID on completion of interrupt OUT transfers
+
+Also add edge case handling for interrupt transports.
+
+Note that for periodic split IN, data toggles are unimplemented in the
+OTG host hardware - it unconditionally accepts any PID.
+
+fiq_fsm: add missing case for fiq_fsm_tt_in_use()
+
+Certain combinations of bitrate and endpoint activity could
+result in a periodic transaction erroneously getting started
+while the previous Isochronous OUT was still active.
+
+fiq_fsm: clear hcintmsk for aborted transactions
+
+Prevents the FIQ from erroneously handling interrupts
+on a timed out channel.
+
+fiq_fsm: enable by default
+
+fiq_fsm: fix dequeues for non-periodic split transactions
+
+If a dequeue happened between the SSPLIT and CSPLIT phases of the
+transaction, the HCD would never receive an interrupt.
+
+fiq_fsm: Disable by default
+
+fiq_fsm: Handle HC babble errors
+
+The HCTSIZ transfer size field raises a babble interrupt if
+the counter wraps. Handle the resulting interrupt in this case.
+
+dwc_otg: fix interrupt registration for fiq_enable=0
+
+Additionally make the module parameter conditional for wherever
+hcd->fiq_state is touched.
+
+fiq_fsm: Enable by default
+
+dwc_otg: Fix various issues with root port and transaction errors
+
+Process the host port interrupts correctly (and don't trample them).
+Root port hotplug now functional again.
+
+Fix a few thinkos with the transaction error passthrough for fiq_fsm.
+
+fiq_fsm: Implement hack for Split Interrupt transactions
+
+Hubs aren't too picky about which endpoint we send Control type split
+transactions to. By treating Interrupt transfers as Control, it is
+possible to use the non-periodic queue in the OTG core as well as the
+non-periodic FIFOs in the hub itself. This massively reduces the
+microframe exclusivity/contention that periodic split transactions
+otherwise have to enforce.
+
+It goes without saying that this is a fairly egregious USB specification
+violation, but it works.
+
+Original idea by Hans Petter Selasky @ FreeBSD.org.
+
+dwc_otg: FIQ support on SMP. Set up FIQ stack and handler on Core 0 only.
+
+dwc_otg: introduce fiq_fsm_spin(un|)lock()
+
+SMP safety for the FIQ relies on register read-modify write cycles being
+completed in the correct order. Several places in the DWC code modify
+registers also touched by the FIQ. Protect these by a bare-bones lock
+mechanism.
+
+This also makes it possible to run the FIQ and IRQ handlers on different
+cores.
+
+fiq_fsm: fix build on bcm2708 and bcm2709 platforms
+
+dwc_otg: put some barriers back where they should be for UP
+
+bcm2709/dwc_otg: Setup FIQ on core 1 if >1 core active
+
+dwc_otg: fixup read-modify-write in critical paths
+
+Be more careful about read-modify-write on registers that the FIQ
+also touches.
+
+Guard fiq_fsm_spin_lock with fiq_enable check
+
+fiq_fsm: Falling out of the state machine isn't fatal
+
+This edge case can be hit if the port is disabled while the FIQ is
+in the middle of a transaction. Make the effects less severe.
+
+Also get rid of the useless return value.
+
+squash: dwc_otg: Allow to build without SMP
+
+usb: core: make overcurrent messages more prominent
+
+Hub overcurrent messages are more serious than "debug". Increase loglevel.
+
+usb: dwc_otg: Don't use dma_to_virt()
+
+Commit 6ce0d20 changes dma_to_virt() which breaks this driver.
+Open code the old dma_to_virt() implementation to work around this.
+
+Limit the use of __bus_to_virt() to cases where transfer_buffer_length
+is set and transfer_buffer is not set. This is done to increase the
+chance that this driver will also work on ARCH_BCM2835.
+
+transfer_buffer should not be NULL if the length is set, but the
+comment in the code indicates that there are situations where this
+might happen. drivers/usb/isp1760/isp1760-hcd.c also has a similar
+comment pointing to a possible: 'usb storage / SCSI bug'.

+dwc_otg: fix summarize urb->actual_length for isochronous transfers
+
+Kernel does not copy input data of ISO transfers to userspace
+if actual_length is set only in ISO transfers and not summarized
+in urb->actual_length. Fixes raspberrypi/linux#903
+
+fiq_fsm: Use correct states when starting isoc OUT transfers
+
+In fiq_fsm_start_next_periodic() if an isochronous OUT transfer
+was selected, no regard was given as to whether this was a single-packet
+transfer or a multi-packet staged transfer.
+
+For single-packet transfers, this had the effect of repeatedly sending
+OUT packets with bogus data and lengths.
+
+Eventually if the channel was repeatedly enabled enough times, this
+would lock up the OTG core and no further bus transfers would happen.
+
+Set the FSM state up properly if we select a single-packet transfer.
+
+Fixes https://github.com/raspberrypi/linux/issues/1842
+
+dwc_otg: make nak_holdoff work as intended with empty queues
+
+If URBs reading from non-periodic split endpoints were dequeued and
+the last transfer from the endpoint was a NAK handshake, the resulting
+qh->nak_frame value was stale which would result in unnecessarily long
+polling intervals for the first subsequent transfer with a fresh URB.
+
+Fixup qh->nak_frame in dwc_otg_hcd_urb_dequeue and also guard against
+a case where a single URB is submitted to the endpoint, a NAK was
+received on the transfer immediately prior to receiving data and the
+device subsequently resubmits another URB past the qh->nak_frame interval.
+
+Fixes https://github.com/raspberrypi/linux/issues/1709
+
+dwc_otg: fix split transaction data toggle handling around dequeues
+
+See https://github.com/raspberrypi/linux/issues/1709
+
+Fix several issues regarding endpoint state when URBs are dequeued
+- If the HCD is disconnected, flush FIQ-enabled channels properly
+- Save the data toggle state for bulk endpoints if the last transfer
+ from an endpoint where URBs were dequeued returned a data packet
+- Reset hc->start_pkt_count properly in assign_and_init_hc()
+
+dwc_otg: fix several potential crash sources
+
+On root port disconnect events, the host driver state is cleared and
+in-progress host channels are forcibly stopped. This doesn't play
+well with the FIQ running in the background, so:
+- Guard the disconnect callback with both the host spinlock and FIQ
+ spinlock
+- Move qtd dereference in dwc_otg_handle_hc_fsm() after the early-out
+ so we don't dereference a qtd that has gone away
+- Turn catch-all BUG()s in dwc_otg_handle_hc_fsm() into warnings.
+
+dwc_otg: delete hcd->channel_lock
+
+The lock serves no purpose as it is only held while the HCD spinlock
+is already being held.
+
+dwc_otg: remove unnecessary dma-mode channel halts on disconnect interrupt
+
+Host channels are already halted in kill_urbs_in_qh_list() with the
+subsequent interrupt processing behaving as if the URB was dequeued
+via HCD callback.
+
+There's no need to clobber the host channel registers a second time
+as this exposes races between the driver and host channel resulting
+in hcd->free_hc_list becoming corrupted.
+

+

+
+dwc_otg: make periodic scheduling behave properly for FS buses
+
+If the root port is in full-speed mode, transfer times at 12mbit/s
+would be calculated but matched against high-speed quotas.
+
+Reinitialise hcd->frame_usecs[i] on each port enable event so that
+full-speed bandwidth can be tracked sensibly.
+
+Also, don't bother using the FIQ for transfers when in full-speed
+mode - at the slower bus speed, interrupt frequency is reduced by
+an order of magnitude.

+dwc_otg: fiq_fsm: Make isochronous compatibility checks work properly

+Get rid of the spammy printk and local pointer mangling.
+Also, there is a nominal benefit for using fiq_fsm for isochronous
+transfers in FS mode (~1.1k IRQs per second vs 2.1k IRQs per second)
+so remove the root port speed check.
+
+dwc_otg: add module parameter int_ep_interval_min
+
+Add a module parameter (defaulting to ignored) that clamps the polling rate
+of high-speed Interrupt endpoints to a minimum microframe interval.
+
+The parameter is modifiable at runtime as it is used when activating new
+endpoints (such as on device connect).
+
+dwc_otg: fiq_fsm: Add non-periodic TT exclusivity constraints
+
+Certain hub types do not discriminate between pipe direction (IN or OUT)
+when considering non-periodic transfers. Therefore these hubs get confused
+if multiple transfers are issued in different directions with the same
+device address and endpoint number.
+
+Constrain queuing non-periodic split transactions so they are performed
+serially in such cases.

++ * The File-backed Storage Gadget acts as a USB Mass Storage device,
++ * appearing to the host as a disk drive or as a CD-ROM drive. In addition
++ * to providing an example of a genuinely useful gadget driver for a USB
++ * device, it also illustrates a technique of double-buffering for increased
++ * throughput. Last but not least, it gives an easy way to probe the
++ * behavior of the Mass Storage drivers in a USB host.
++ *
++ * Backing storage is provided by a regular file or a block device, specified
++ * by the "file" module parameter. Access can be limited to read-only by
++ * setting the optional "ro" module parameter. (For CD-ROM emulation,
++ * access is always read-only.) The gadget will indicate that it has
++ * removable media if the optional "removable" module parameter is set.
++ *
++ * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
++ * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
++ * by the optional "transport" module parameter. It also supports the
++ * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
++ * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
++ * the optional "protocol" module parameter. In addition, the default
++ * Vendor ID, Product ID, release number and serial number can be overridden.
++ *
++ * There is support for multiple logical units (LUNs), each of which has
++ * its own backing file. The number of LUNs can be set using the optional
++ * "luns" module parameter (anywhere from 1 to 8), and the corresponding
++ * files are specified using comma-separated lists for "file" and "ro".
++ * The default number of LUNs is taken from the number of "file" elements;
++ * it is 1 if "file" is not given. If "removable" is not set then a backing
++ * file must be specified for each LUN. If it is set, then an unspecified
++ * or empty backing filename means the LUN's medium is not loaded. Ideally
++ * each LUN would be settable independently as a disk drive or a CD-ROM
++ * drive, but currently all LUNs have to be the same type. The CD-ROM
++ * emulation includes a single data track and no audio tracks; hence there
++ * need be only one backing file per LUN.
++ *
++ * Requirements are modest; only a bulk-in and a bulk-out endpoint are
++ * needed (an interrupt-out endpoint is also needed for CBI). The memory
++ * requirement amounts to two 16K buffers, size configurable by a parameter.
++ * Support is included for both full-speed and high-speed operation.
++ *
++ * Note that the driver is slightly non-portable in that it assumes a
++ * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
++ * interrupt-in endpoints. With most device controllers this isn't an
++ * issue, but there may be some with hardware restrictions that prevent
++ * a buffer from being used by more than one endpoint.
++ *
++ * Module options:
++ *
++ * file=filename[,filename...]
++ * Required if "removable" is not set, names of
++ * the files or block devices used for
++ * backing storage
++ * serial=HHHH... Required serial number (string of hex chars)
++ * ro=b[,b...] Default false, booleans for read-only access
++ * removable Default false, boolean for removable media
++ * luns=N Default N = number of filenames, number of
++ * LUNs to support
++ * nofua=b[,b...] Default false, booleans for ignore FUA flag
++ * in SCSI WRITE(10,12) commands
++ * stall Default determined according to the type of
++ * USB device controller (usually true),
++ * boolean to permit the driver to halt
++ * bulk endpoints
++ * cdrom Default false, boolean for whether to emulate
++ * a CD-ROM drive
++ * transport=XXX Default BBB, transport name (CB, CBI, or BBB)
++ * protocol=YYY Default SCSI, protocol name (RBC, 8020 or
++ * ATAPI, QIC, UFI, 8070, or SCSI;
++ * also 1 - 6)
++ * vendor=0xVVVV Default 0x0525 (NetChip), USB Vendor ID
++ * product=0xPPPP Default 0xa4a5 (FSG), USB Product ID
++ * release=0xRRRR Override the USB release number (bcdDevice)
++ * buflen=N Default N=16384, buffer size used (will be

++
++
++/*
++ * Driver Design
++ *
++ * The FSG driver is fairly straightforward. There is a main kernel
++ * thread that handles most of the work. Interrupt routines field
++ * callbacks from the controller driver: bulk- and interrupt-request
++ * completion notifications, endpoint-0 events, and disconnect events.
++ * Completion events are passed to the main thread by wakeup calls. Many
++ * ep0 requests are handled at interrupt time, but SetInterface,
++ * SetConfiguration, and device reset requests are forwarded to the
++ * thread in the form of "exceptions" using SIGUSR1 signals (since they
++ * should interrupt any ongoing file I/O operations).
++ *
++ * The thread's main routine implements the standard command/data/status
++ * parts of a SCSI interaction. It and its subroutines are full of tests
++ * for pending signals/exceptions -- all this polling is necessary since
++ * the kernel has no setjmp/longjmp equivalents. (Maybe this is an
++ * indication that the driver really wants to be running in userspace.)
++ * An important point is that so long as the thread is alive it keeps an
++ * open reference to the backing file. This will prevent unmounting
++ * the backing file's underlying filesystem and could cause problems
++ * during system shutdown, for example. To prevent such problems, the
++ * thread catches INT, TERM, and KILL signals and converts them into
++ * an EXIT exception.
++ *
++ * In normal operation the main thread is started during the gadget's
++ * fsg_bind() callback and stopped during fsg_unbind(). But it can also
++ * exit when it receives a signal, and there's no point leaving the
++ * gadget running when the thread is dead. So just before the thread
++ * exits, it deregisters the gadget driver. This makes things a little
++ * tricky: The driver is deregistered at two places, and the exiting
++ * thread can indirectly call fsg_unbind() which in turn can tell the
++ * thread to exit. The first problem is resolved through the use of the
++ * REGISTERED atomic bitflag; the driver will only be deregistered once.
++ * The second problem is resolved by having fsg_unbind() check
++ * fsg->state; it won't try to stop the thread if the state is already
++ * FSG_STATE_TERMINATED.
++ *
++ * To provide maximum throughput, the driver uses a circular pipeline of
++ * buffer heads (struct fsg_buffhd). In principle the pipeline can be
++ * arbitrarily long; in practice the benefits don't justify having more
++ * than 2 stages (i.e., double buffering). But it helps to think of the
++ * pipeline as being a long one. Each buffer head contains a bulk-in and
++ * a bulk-out request pointer (since the buffer can be used for both
++ * output and input -- directions always are given from the host's
++ * point of view) as well as a pointer to the buffer and various state
++ * variables.
++ *
++ * Use of the pipeline follows a simple protocol. There is a variable
++ * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
++ * At any time that buffer head may still be in use from an earlier
++ * request, so each buffer head has a state variable indicating whether
++ * it is EMPTY, FULL, or BUSY. Typical use involves waiting for the
++ * buffer head to be EMPTY, filling the buffer either by file I/O or by
++ * USB I/O (during which the buffer head is BUSY), and marking the buffer
++ * head FULL when the I/O is complete. Then the buffer will be emptied
++ * (again possibly by USB I/O, during which it is marked BUSY) and
++ * finally marked EMPTY again (possibly by a completion routine).
++ *
++ * A module parameter tells the driver to avoid stalling the bulk
++ * endpoints wherever the transport specification allows. This is
++ * necessary for some UDCs like the SuperH, which cannot reliably clear a
++ * halt on a bulk endpoint. However, under certain circumstances the
++ * Bulk-only specification requires a stall. In such cases the driver
++ * will halt the endpoint and set a flag indicating that it should clear
++ * the halt in software during the next device reset. Hopefully this
++ * will permit everything to work correctly. Furthermore, although the
++ * specification allows the bulk-out endpoint to halt when the host sends
++ * too much data, implementing this would cause an unavoidable race.
++ * The driver will always use the "no-stall" approach for OUT transfers.
++ *
++ * One subtle point concerns sending status-stage responses for ep0
++ * requests. Some of these requests, such as device reset, can involve
++ * interrupting an ongoing file I/O operation, which might take an
++ * arbitrarily long time. During that delay the host might give up on
++ * the original ep0 request and issue a new one. When that happens the
++ * driver should not notify the host about completion of the original
++ * request, as the host will no longer be waiting for it. So the driver
++ * assigns to each ep0 request a unique tag, and it keeps track of the
++ * tag value of the request associated with a long-running exception
++ * (device-reset, interface-change, or configuration-change). When the
++ * exception handler is finished, the status-stage response is submitted
++ * only if the current ep0 request tag is equal to the exception request
++ * tag. Thus only the most recently received ep0 request will get a
++ * status-stage response.
++ *
++ * Warning: This driver source file is too long. It ought to be split up
++ * into a header file plus about 3 separate .c files, to handle the details
++ * of the Gadget, USB Mass Storage, and SCSI protocols.
