* V4L/DVB: uvc: Move constants and structures definitions to linux/usb/video.hLaurent Pinchart2010-08-021-0/+397
| | | | | | | | | | | The UVC host and gadget drivers both define constants and structures in private header files. Move all those definitions to linux/usb/video.h where they can be shared by the two drivers (and be available for userspace applications).

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.

| * USB: serial: remove multi-urb write from generic driverJohan Hovold2010-05-201-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * USB: serial: reimplement generic fifo-based writesJohan Hovold2010-05-201-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * USB: Support for allocating USB 3.0 streams.Sarah Sharp2010-05-201-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bulk endpoint streams were added in the USB 3.0 specification. Streams allow a device driver to overload a bulk endpoint so that multiple transfers can be queued at once. The device then decides which transfer it wants to work on first, and can queue part of a transfer before it switches to a new stream. All this switching is invisible to the device driver, which just gets a completion for the URB. Drivers that use streams must be able to handle URBs completing in a different order than they were submitted to the endpoint. This requires adding new API to set up xHCI data structures to support multiple queues ("stream rings") per endpoint. Drivers will allocate a number of stream IDs before enqueueing URBs to the bulk endpoints of the device, and free the stream IDs in their disconnect function. See Documentation/usb/bulk-streams.txt for details. The new mass storage device class, USB Attached SCSI Protocol (UASP), uses these streams API.

| * USB: serial: generalise write buffer preparationJohan Hovold2010-05-201-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generalise write buffer preparation. This allows for drivers to manipulate (e.g. add headers) to bulk out data before it is sent. This adds a new function pointer to usb_serial_driver: int (*prepare_write_buffer)(struct usb_serial_port *port, void **dest, size_t size, const void *src, size_t count); The function is generic and can be used with either kfifo-based or multi-urb writes: If *dest is NULL the implementation should allocate dest. If src is NULL the implementation should use the port write fifo. If not set, a generic implementation is used which simply uses memcpy or kfifo_out.

Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
