These all remain +unchanged between paired calls of CGUIShader::OnEnabled and +CGUIShader::OnDisabled, so we scan the matrices in CGUIShader::OnEnabled to +see whether hardware clipping is possible. + +Then, in CGUIFontTTFBase::RenderCharacter, we don't apply software clipping +in such cases. However, because vertices arising from multiple +CGUIFontTTFBase::DrawTextInternal calls (each of which often uses a different +clip rectangle) get lumped into the same vector, which only at the end is +passed to OpenGL for rendering, we need to wait a few commits before we can +actually apply hardware clipping.

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 ++ * rounded down to a multiple of ++ * PAGE_CACHE_SIZE) ++ * ++ * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro", ++ * "removable", "luns", "nofua", "stall", and "cdrom" options are available; ++ * default values are used for everything else. ++ * ++ * The pathnames of the backing files and the ro settings are available in ++ * the attribute files "file", "nofua", and "ro" in the lun subdirectory of ++ * the gadget's sysfs directory. If the "removable" option is set, writing to ++ * these files will simulate ejecting/loading the medium (writing an empty ++ * line means eject) and adjusting a write-enable tab. Changes to the ro ++ * setting are not allowed when the medium is loaded or if CD-ROM emulation ++ * is being used. ++ * ++ * This gadget driver is heavily based on "Gadget Zero" by David Brownell. ++ * The driver's SCSI command interface was based on the "Information ++ * technology - Small Computer System Interface - 2" document from ++ * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at ++ * . The single exception ++ * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the ++ * "Universal Serial Bus Mass Storage Class UFI Command Specification" ++ * document, Revision 1.0, December 14, 1998, available at ++ * . ++ */ ++ ++ ++/* ++ * 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. ++ */ ++ ++ ++/* #define VERBOSE_DEBUG */ ++/* #define DUMP_MSGS */ ++ ++ ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++ ++#include ++#include ++ ++#include "gadget_chips.h" ++ ++ ++ ++/* ++ * Kbuild is not very cooperative with respect to linking separately ++ * compiled library objects into one module.

The observable ++ * modules do not need to know any information about it's observers or their ++ * interface, or their state or data. ++ * ++ * Any module can register to emit Notifications. It should publish a list of ++ * notifications that it can emit and their behavior, such as when they will get ++ * triggered, and what information will be provided to the observer.

The WUDEV ++ * driver uses only these functions. In order to port the WUDEV driver, only ++ * the functions in this library need to be re-implemented, with the same ++ * behavior as documented here. ++ * ++ * The Common library consists of higher level functions, which rely only on ++ * calling the functions from the DWC Portability library. These common ++ * routines are shared across modules. Some of the common libraries need to be ++ * used directly by the driver programmer when porting WUDEV. Such as the ++ * parameter and notification libraries. ++ * ++ * @section low Portability Library OS Wrapper Functions ++ * ++ * Any function starting with DWC and in all CAPS is a low-level OS-wrapper that ++ * needs to be implemented when porting, for example DWC_MUTEX_ALLOC(). All of ++ * these functions are included in the dwc_os.h file. ++ * ++ * There are many functions here covering a wide array of OS services. Please ++ * see dwc_os.h for details, and implementation notes for each function. ++ * ++ * @section common Common Library Functions ++ * ++ * Any function starting with dwc and in all lowercase is a common library ++ * routine. These functions have a portable implementation and do not need to ++ * be reimplemented when porting. The common routines can be used by any ++ * driver, and some must be used by the end user to control the drivers. For ++ * example, you must use the Parameter common library in order to set the ++ * parameters in the WUDEV module. ++ * ++ * The common libraries consist of the following: ++ * ++ * - Connection Contexts - Used internally and can be used by end-user. See dwc_cc.h ++ * - Parameters - Used internally and can be used by end-user. See dwc_params.h ++ * - Notifications - Used internally and can be used by end-user. See dwc_notifier.h ++ * - Lists - Used internally and can be used by end-user. See dwc_list.h ++ * - Memory Debugging - Used internally and can be used by end-user. See dwc_os.h ++ * - Modpow - Used internally only. See dwc_modpow.h ++ * - DH - Used internally only. See dwc_dh.h ++ * - Crypto - Used internally only. See dwc_crypto.h ++ * ++ * ++ * @section prereq Prerequistes For dwc_os.h ++ * @subsection types Data Types ++ * ++ * The dwc_os.h file assumes that several low-level data types are pre defined for the ++ * compilation environment. These data types are: ++ * ++ * - uint8_t - unsigned 8-bit data type ++ * - int8_t - signed 8-bit data type ++ * - uint16_t - unsigned 16-bit data type ++ * - int16_t - signed 16-bit data type ++ * - uint32_t - unsigned 32-bit data type ++ * - int32_t - signed 32-bit data type ++ * - uint64_t - unsigned 64-bit data type ++ * - int64_t - signed 64-bit data type ++ * ++ * Ensure that these are defined before using dwc_os.h. The easiest way to do ++ * that is to modify the top of the file to include the appropriate header. ++ * This is already done for the Linux environment. If the DWC_LINUX macro is ++ * defined, the correct header will be added. A standard header is ++ * also used for environments where standard C headers are available. ++ * ++ * @subsection stdarg Variable Arguments ++ * ++ * Variable arguments are provided by a standard C header . it is ++ * available in Both the Linux and ANSI C enviornment. An equivalent must be ++ * provided in your enviornment in order to use dwc_os.h with the debug and ++ * tracing message functionality. ++ * ++ * @subsection thread Threading ++ * ++ * WUDEV Core must be run on an operating system that provides for multiple ++ * threads/processes. Threading can be implemented in many ways, even in ++ * embedded systems without an operating system. At the bare minimum, the ++ * system should be able to start any number of processes at any time to handle ++ * special work. It need not be a pre-emptive system. Process context can ++ * change upon a call to a blocking function. The hardware interrupt context ++ * that calls the module's ISR() function must be differentiable from process ++ * context, even if your processes are impemented via a hardware interrupt. ++ * Further locking mechanism between process must exist (or be implemented), and ++ * process context must have a way to disable interrupts for a period of time to ++ * lock them out. If all of this exists, the functions in dwc_os.h related to ++ * threading should be able to be implemented with the defined behavior. ++ * ++ */ ++ ++#ifdef __cplusplus ++} ++#endif ++ ++#endif /* _DWC_OS_H_ */ +diff --git a/drivers/usb/host/dwc_common_port/usb.h b/drivers/usb/host/dwc_common_port/usb.h +new file mode 100644 +index 0000000..27bda82 +--- /dev/null ++++ b/drivers/usb/host/dwc_common_port/usb.h +@@ -0,0 +1,946 @@ ++/* ++ * Copyright (c) 1998 The NetBSD Foundation, Inc. ++ * All rights reserved. ++ * ++ * This code is derived from software contributed to The NetBSD Foundation ++ * by Lennart Augustsson (lennart@augustsson.net) at ++ * Carlstedt Research & Technology. ++ * ++ * Redistribution and use in source and binary forms, with or without ++ * modification, are permitted provided that the following conditions ++ * are met: ++ * 1.

By creating +special case functions for 16bpp and 32bpp, by far the most common pixel +formats used on modern systems, a significant speed-up is attained +which can be readily felt on ARM-based devices like the Raspberry Pi +and the Allwinner platform, but should help any platform using the +fb layer. + +The special case functions allow constant folding, eliminating a number +of instructions including divide operations, and allow the use of an +unrolled loop, eliminating instructions with a variable shift size, +reducing source memory access instructions, and eliminating excessive +branching. These unrolled loops also allow much better code optimization +by the C compiler. The code that selects which optimized variant is used +is also simplified, eliminating integer divide instructions. + +The speed-up, measured by timing 'cat file.txt' in the console, varies +between 40% and 70%, when testing on the Raspberry Pi and Allwinner +ARM-based platforms, depending on font size and the pixel depth, with +the greater benefit for 32bpp. + +Signed-off-by: Harm Hanemaaijer +--- + drivers/video/fbdev/core/cfbimgblt.c | 152 +++++++++++++++++++++++++++++++++-- + 1 file changed, 147 insertions(+), 5 deletions(-) + +diff --git a/drivers/video/fbdev/core/cfbimgblt.c b/drivers/video/fbdev/core/cfbimgblt.c +index a2bb276..436494f 100644 +--- a/drivers/video/fbdev/core/cfbimgblt.c ++++ b/drivers/video/fbdev/core/cfbimgblt.c +@@ -28,6 +28,11 @@ + * + * Also need to add code to deal with cards endians that are different than + * the native cpu endians.

23:42:01 +0100 +Subject: [PATCH 10/76] bcm2708 vchiq driver + +Signed-off-by: popcornmix + +vchiq: create_pagelist copes with vmalloc memory + +Signed-off-by: Daniel Stone + +vchiq: fix the shim message release + +Signed-off-by: Daniel Stone + +vchiq: export additional symbols + +Signed-off-by: Daniel Stone + +VCHIQ: Make service closure fully synchronous (drv) + +This is one half of a two-part patch, the other half of which is to +the vchiq_lib user library. With these patches, calls to +vchiq_close_service and vchiq_remove_service won't return until any +associated callbacks have been delivered to the callback thread. + +VCHIQ: Add per-service tracing + +The new service option VCHIQ_SERVICE_OPTION_TRACE is a boolean that +toggles tracing for the specified service. + +This commit also introduces vchi_service_set_option and the associated +option VCHI_SERVICE_OPTION_TRACE. + +vchiq: Make the synchronous-CLOSE logic more tolerant + +vchiq: Move logging control into debugfs + +vchiq: Take care of a corner case tickled by VCSM + +Closing a connection that isn't fully open requires care, since one +side does not know the other side's port number. Code was present to +handle the case where a CLOSE is sent immediately after an OPEN, i.e. +before the OPENACK has been received, but this was incorrectly being +used when an OPEN from a client using port 0 was rejected. + +(In the observed failure, the host was attempting to use the VCSM +service, which isn't present in the 'cutdown' firmware. The failure +was intermittent because sometimes the keepalive service would +grab port 0.) + +This case can be distinguished because the client's remoteport will +still be VCHIQ_PORT_FREE, and the srvstate will be OPENING. Either +condition is sufficient to differentiate it from the special case +described above. +--- + drivers/misc/Kconfig | 1 + + drivers/misc/Makefile | 1 + + drivers/misc/vc04_services/Kconfig | 9 + +

We therefore also reset the ++** resume state machine to VC_RESUME_IDLE in this state. ++** ++** VC_SUSPEND_SUSPENDED - Suspend has completed successfully. Also call ++** complete_all on the suspend completion to notify ++** anything waiting for suspend to happen. ++** ++** VC_SUSPEND_REJECTED - Videocore rejected suspend. Videocore will also ++** initiate resume, so no need to alter resume state. ++** We call complete_all on the suspend completion to notify ++** of suspend rejection. ++** ++** VC_SUSPEND_FAILED - We failed to initiate videocore suspend. We notify the ++** suspend completion and reset the resume state machine. ++** ++** VC_RESUME_IDLE - Initialise the resume completion at the same time. The ++** resume completion is in it's 'done' state whenever ++** videcore is running. Therfore, the VC_RESUME_IDLE state ++** implies that videocore is suspended. ++** Hence, any thread which needs to wait until videocore is ++** running can wait on this completion - it will only block ++** if videocore is suspended. ++** ++** VC_RESUME_RESUMED - Resume has completed successfully.

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: whitespace cleanup in dwc_otg_urb_enqueue + +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.

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.

External audio codecs can be +connected to the Raspberry Pi via P5 header. + +It relies on cyclic DMA engine support for BCM2708. + +Signed-off-by: Florian Meier + +ASoC: BCM2708: Add 24 bit support + +This adds 24 bit support to the I2S driver of the BCM2708. +Besides enabling the 24 bit flags, it includes two bug fixes: + +MMAP is not supported. Claiming this leads to strange issues +when the format of driver and file do not match. + +The datasheet states that the width extension bit should be set +for widths greater than 24, but greater or equal would be correct. +This follows from the definition of the width field. + +Signed-off-by: Florian Meier + +bcm2708-i2s: Update bclk_ratio to more correct values + +Move GPIO setup to hw_params. + +This is used to stop the I2S driver from breaking +the GPIO setup for other uses of the PCM interface + +Configure GPIOs for I2S based on revision/card settings + +With RPi model B+, assignment of the I2S GPIO pins has changed. +This patch uses the board revision to auto-detect the GPIOs used +for I2S. It also allows sound card drivers to set the GPIOs that +should be used. This is especially important with the Compute +Module. + +bcm2708-i2s: Avoid leak from iomap when accessing gpio + +bcm2708: Eliminate i2s debugfs directory error + +Qualify the two regmap ranges uses by bcm2708-i2s ('-i2s' and '-clk') +to avoid the name clash when registering debugfs entries. +--- + sound/soc/bcm/Kconfig | 11 + + sound/soc/bcm/Makefile | 4 + + sound/soc/bcm/bcm2708-i2s.c | 998 ++++++++++++++++++++++++++++++++++++++++++++ + sound/soc/bcm/bcm2708-i2s.h | 35 ++ + 4 files changed, 1048 insertions(+) + create mode 100644 sound/soc/bcm/bcm2708-i2s.c + create mode 100644 sound/soc/bcm/bcm2708-i2s.h + +diff --git a/sound/soc/bcm/Kconfig b/sound/soc/bcm/Kconfig +index 6a834e1..7e5b945 100644 +--- a/sound/soc/bcm/Kconfig ++++ b/sound/soc/bcm/Kconfig +@@ -7,3 +7,14 @@ config SND_BCM2835_SOC_I2S + Say Y or M if you want to add support for codecs attached to + the BCM2835 I2S interface.

At 192kHz only 128xfs is supported. The existing driver + selects 128xfs automatically for some lower samples rates.

It + should allow lower jitter and better signal quality. The behavior has to be + controlled by the sound card driver, because some sample frequency share the + same setting. e.g. 192kHz and 96kHz use 24.576MHz master clock.
