2008-04-24V4L/DVB (7541): em28xx: Some fixes to videobufAidan Thornton
It fixes a couple of minor bugs, comments out a bogus BUG_ON, sets fh->type correctly, uses dev->width and dev->height for now, and adds a missing spinlock init (nasty - caused a system lockup). It also adds some debug code which probably isn't all that useful. I haven't tested this version of the patch yet, though, so I'm not sure what you can expect if you try it.

2008-04-24V4L/DVB (7540): em28xx: convert to use videobuf-vmallocMauro Carvalho Chehab
The usage of videobuf-vmalloc allows to cleanup em28xx logic. Also, it reduced its size by about 5.42% on i386 arch (and about 7.5% on x86_64): 39113 4876 40 44029 abfd old/em28xx.ko 36731 4868 40 41639 a2a7 /home/v4l/master/v4l/em28xx.ko Also, the preliminary tests, made on a single core 1.5 MHz Centrino showed that CPU usage reduced from 42%-75% to 28%-33% (reports from "top") command. A test with time command presented an even better result: This is the performance tests I did, running code_example to get 1,000 frames @29.995 Hz (about 35 seconds of stream), tested on a i386 machine, running at 1,5GHz: The old driver: $ time -f "%E: %Us User time, %Ss Kernel time, %P CPU used" ./capture_example 0:34.21: 8.22s User time, 25.16s Kernel time, 97% CPU used The videobuf-based driver: $ time -f "%E: %Us User time, %Ss Kernel time, %P CPU used" ./capture_example 0:35.36: 0.01s User time, 0.05s Kernel time, 0% CPU used Conclusion: The time consumption to receive the stream where reduced from about 33.38 seconds to 0.05 seconds.

2008-04-24V4L/DVB (7538): Adds selectable adapter numbers as per module optionJanne Grunau
The adapter_nr module options can be used to allocate static adapter numbers on a driver level. It avoids problems with changing DVB apapter numbers after warm/cold boot or device unplugging and repluging. Each driver holds DVB_MAX_ADAPTER long array of the preferred order of adapter numbers. options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a reversed allocation of adapter numbers. With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If both are already in use it will allocate the lowest free adapter number.

empty queue Add a waitqueue to wait on when there are no buffers in the buffer queue. DQBUF waits on this queue without holding vb_lock to allow a QBUF to happen. Once a buffer has been queued we recheck that the queue is still streaming and wait on the new buffer's waitqueue while holding the vb_lock. The driver should come along in a timely manner and put the buffer into its next state finishing the DQBUF. By implementing this waitqueue it also brings the videobuf DQBUF up to spec and it now blocks on O_NONBLOCK even when no buffers have been queued via QBUF: "By default VIDIOC_DQBUF blocks when no buffer is in the outgoing queue." - V4L2 spec Signed-off-by: Brandon Philips <bphilips@suse.de> CC: Trent Piepho <xyzzy@speakeasy.org> CC: Carl Karsten <carl@personnelware.com> CC: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7492): vivi: Simplify the vivi driver and avoid deadlocksBrandon Philips
vivi previously had a very complex queuing system and held spinlocks while doing copy_to_user, kmalloc, etc. This caused the driver to easily deadlock when a multi-threaded application used it and revealed bugs in videobuf too. This replaces the copy_to_user with memcpy since we were never copying to user space addresses. And makes the kmalloc atomic.
