2010-05-20USB: isp1760: Soften DW3 X/transaction error bit handlingAnton Vorontsov1-4/+3
There were some reports[1] of isp1760 USB driver malfunctioning with high speed devices, noticed on Blackfin and PowerPC targets. These reports indicated that the original Philips 'pehcd'[2] driver worked fine. We've noticed the same issue with an ARM RealView platform. This happens under load (with only some mass storage devices, not all, just as in another report[3]): error bit is set in DW3 error bit is set in DW3 error bit is set in DW3 usb 1-1.2: device descriptor read/64, error -32 It appears that the 'pehcd' driver checks the X bit only if the transaction is halted (H bit), otherwise the error is so far insignificant. The ISP176x chips were modeled after EHCI, and EHCI spec says (thanks to Alan Stern for pointing out): "Transaction errors cause the status field to be updated to reflect the type of error, but the transaction continues to be retried until the Active bit is set to 0. When the error counter reaches 0, the Halt bit is set and the Active bit is cleared." So, just as the original Philips driver, isp1760 must report the error only if the transaction error and the halt bits are set.

2010-05-20USB: usbcore: Do not disable USB3 protocol ports in hub_activate()Andiry Xu1-2/+14
When USB3 protocol port detects an USB3.0 device attach, the port will automatically transition to the Enabled state upon the completion of successful link training. Do not disable USB3 protocol ports in hub_activate(), or USB3.0 device will fail to be recognized if xHCI bus power management is implemented.

2010-05-20USB: gadget: Allow function access to device ID data during bind()Robert Lukassen1-8/+8
This is a patch that makes sure that the device ID data (idVendor, idProduct and bcdDevice) are assigned to the descriptor in the cdev structure *before* the composite gadget starts binding. This allows the composite driver, and all the composite functions it uses, access to that data. In one of the composite functions we created, we needed to register an input device and wanted to use the idVendor, idProduct and bcdDevice codes to properly initialize the id field of the input device. We could not do that because the idVendor, idProduct and bcdDevice values were only set in the cdec structure *after* the composite->bind(cdev) call.

The FunctionFS gadget may provide the source/sink interface not as the first interface (with id == 0) but some different interface hence a code to find the interface number is required. (Note that you will still configure the gadget to report idProduct == 0xa4a4 (an "echo 0xa4a4 >/sys/module/g_ffs/parameters/usb_product" should suffice) or configure host to handle 0x0525:0xa4ac devices using the usbtest driver.)

2010-05-20USB: g_ffs: the FunctionFS gadget driverMichal Nazarewicz3-0/+465
The Function Filesystem (FunctioFS) lets one create USB composite functions in user space in the same way as GadgetFS lets one create USB gadgets in user space. This allows creation of composite gadgets such that some of the functions are implemented in kernel space (for instance Ethernet, serial or mass storage) and other are implemented in user space.

2010-05-20USB: f_fs: the FunctionFS driverMichal Nazarewicz2-0/+2640
The FunctionFS is a USB composite function that can be used with the composite framework to create an USB gadget. >From kernel point of view it is just a composite function with some unique behaviour. It may be added to an USB configuration only after the user space driver has registered by writing descriptors and strings (the user space program has to provide the same information that kernel level composite functions provide when they are added to the configuration). >From user space point of view it is a file system which when mounted provide an "ep0" file. User space driver need to write descriptors and strings to that file. It does not need to worry about endpoints, interfaces or strings numbers but simply provide descriptors such as if the function was the only one (endpoints and strings numbers starting from one and interface numbers starting from core). The FunctionFS changes numbers of those as needed also handling situation when numbers differ in different configurations. When descriptors and strings are written "ep#" files appear (one for each declared endpoint) which handle communication on a single endpoint. Again, FunctionFS takes care of the real numbers and changing of the configuration (which means that "ep1" file may be really mapped to (say) endpoint 3 (and when configuration changes to (say) endpoint 2)). "ep0" is used for receiving events and handling setup requests. When all files are closed the function disables itself.

2010-05-20wait_event_interruptible_locked() interfaceMichal Nazarewicz2-0/+150
New wait_event_interruptible{,_exclusive}_locked{,_irq} macros added. They work just like versions without _locked* suffix but require the wait queue's lock to be held. Also __wake_up_locked() is now exported as to pair it with the above macros. The use case of this new facility is when one uses wait queue's lock to protect a data structure. This may be advantageous if the structure needs to be protected by a spinlock anyway. In particular, with additional spinlock the following code has to be used to wait for a condition: spin_lock(&data.lock); ... for (ret = 0; !ret && !(condition); ) { spin_unlock(&data.lock); ret = wait_event_interruptible(data.wqh, (condition)); spin_lock(&data.lock); } ... spin_unlock(&data.lock); This looks bizarre plus wait_event_interruptible() locks the wait queue's lock anyway so there is a unlock+lock sequence where it could be avoided. To avoid those problems and benefit from wait queue's lock, a code similar to the following should be used: /* Waiting */ spin_lock(&data.wqh.lock); ... ret = wait_event_interruptible_locked(data.wqh, (condition)); ... spin_unlock(&data.wqh.lock); /* Waiting exclusively */ spin_lock(&data.whq.lock); ... ret = wait_event_interruptible_exclusive_locked(data.whq, (condition)); ... spin_unlock(&data.whq.lock); /* Waking up */ spin_lock(&data.wqh.lock); ... wake_up_locked(&data.wqh); ... spin_unlock(&data.wqh.lock); When spin_lock_irq() is used matching versions of macros need to be used (*_locked_irq()).

2010-05-20USB: serial: remove multi-urb write from generic driverJohan Hovold4-176/+48
Remove multi-urb write from the generic driver and simplify the prepare_write_buffer prototype: int (*prepare_write_buffer)(struct usb_serial_port *port, void *dest, size_t size); The default implementation simply fills dest with data from port write fifo but drivers can override it if they need to process the outgoing data (e.g. add headers). Turn ftdi_sio into a generic fifo-based driver, which lowers CPU usage significantly for small writes while retaining maximum throughput.

2010-05-20USB: serial: reimplement generic fifo-based writesJohan Hovold3-20/+84
Reimplement fifo-based writes in the generic driver using a multiple pre-allocated urb scheme. In contrast to multi-urb writes, no allocations (of urbs or buffers) are made during run-time and there is less pressure on the host stack queues as currently only two urbs are used (implementation is generic and can handle more than two urbs as well, though). Initial tests using ftdi_sio show that the implementation achieves the same (maximum) throughput at high baudrates as multi-urb writes. The CPU usage is much lower than for multi-urb writes for small write requests and only slightly higher for large (e.g. 2k) requests (due to extra copy via fifo?). Also outperforms multi-urb writes for small write requests on an embedded arm-9 system, where multi-urb writes are CPU-bound at high baudrates (perf reveals that a lot of time is spent in the host stack enqueue function -- could perhaps be a bug as well). Keeping the original write_urb, buffer and flag for now as there are other drivers depending on them.

Switch to the generic, multi-urb, write implementation.

This may be desirable for instance on an embedded system where optimal throughput at high baudrates may not be as important as other factors (e.g. no allocations during runtime and less pressure on host stack).
