The initial work to convert the bttv driver to V4L2 "Partial conversion from V4L1 to V4L2" (e84619b1 ), missed the line which set the appropriate overlay crop structure in the newly allocated bttv_buffer. This then causes a divide error in the bttv_calc_geo function. Signed-off-by:

It currently isn't possible to open the frontend device of cx88-mpeg devices (DVB or Blackbird) multiple times concurrently. (for instance, to attach a signal monitoring tool while reading a stream, or to send a frequency change ioctl) This patch fixes that condition. Signed-off-by:

This patch combines all the finished discussions and its resulting patches from the mailing list. The version 1.0.6 is mainly influenced by Oliver Neukum. He found a lot of small issues, that are fixed with this patch now. For me the most interesting thing is, that it's now safer to use it on other architectures. The history for version 1.0.6 is: - fixed coverity checker warnings in *_usb_driver_disconnect - probe()/open() race by correct ordering in probe() - DMA coherency rules by separate allocation of all buffers - use of endianness macros - abuse of spinlock, replaced by mutex - racy handling of timer in disconnect, replaced by delayed_work - racy interruptible_sleep_on(), replaced with wait_event_interruptible() - handle signals in read() The driver is tested with all Debian/testing radio programs and rdsd. The patch is tested against checkpatch.pl v1.12. Signed-off-by:

em28xx driver is capable of handling more than one usb device. However, isoc transfers require a large amount of data to be transfered. Before this patch, just one em28xx board were enough to allocate more than 50% URBs: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc=480/800 us (60%), #Int= 0, #Iso= 2 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 So, only one board could use an USB host at the same time. After the patch, it is possible to use more than one em28xx at the same time, on the same usb host, if the image size is slower or equal to 345600, since those images will require about 30% of the URBs: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc=232/800 us (29%), #Int= 0, #Iso= 2 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 So, in thesis, after the patch, it would be possible to use up to 3 boards by each usb host, if the devices are generating small images.
