- Aborting buffer_filled if no-one's waiting on the waitqueue probably isn't what we want, since just because no-one's waiting for it now doesn't mean they wouldn't dequeue it in time. (vivi gets away with this, possibly because it can fill each buffer much faster.) - The first BUG_ON(lencopy <= 0); really isn't worth causing a kernel panic over, especially since there are some reasons why it could trigger in normal use. - The top and botom frames are actually the wrong way around.

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. Signed-off-by:

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.

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. Signed-off-by:

If frontend is not attached, both cx88-dvb and saa7134-dvb don't register DVB. However, dvb unregister were inconditionally called. Due to that, an OOPS is generated. Signed-off-by: -

Added the last remaining out-of-tree kernel driver from the ivtv project. The saa717x is used in several Japanese cards and a Russian card. The driver is not complete in that only NTSC is supported and no PAL/SECAM. Hopefully this will be added in the future. Signed-off-by:

Quoting the commit introducing reinitialise_demod (3984 / by adq): "These cards [KNC1 DVBT and DVBC] need special handling for CI - reinitialising the frontend device when the CI module is reset." Apparently my 1894:0010 also needs that fix, because once you initialise CI/CAM you lose lock. Signed-off-by:

The current ci implementation doesn't accept 0xff when reading data bytes (address == 0), thus breaks cams which report a buffer size of 0x--ff like my orion one. Remove the 0xff check altogether, because validation is really the job of a higher layer. Signed-off-by:
