* V4L/DVB (7594): em28xx: Fix KconfigMauro Carvalho Chehab2008-04-241-1/+2
| | | | | | Some devices have msp3400 audio decoder chip. Selects it, if em28xx. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (7593): em28xx: add a module to handle dvbMauro Carvalho Chehab2008-04-246-24/+218
| | | | | | | | | | | This patch adds em28xx-dvb. This driver is highly based on cx88-dvb and saa7134-dvb. This code currently loads and unloads successfully. However, some changes are needed to properly support the mpeg streams and to setup em28xx to work on DVB mode. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (7591): drivers/media/video: use time_before, time_before_eq, etcJulia Lawall2008-04-244-8/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values.

* V4L/DVB (7590): ir-common: Adds 3 missing IR keys for FlyVIdeo2000Ivan Bobyr2008-04-241-1/+5
| | | | | | | | | | | | | | | | | | | | | The patch extends the default keymap of FlyVIdeo2000 IR remote control so that this remote may also serve movie & music players in a better way. I bought a SAA7130 TV tuner with a remote control having 3 additional button as the default layout, exactly as: 1) labeled "<<<" : key code 0x19, may be used as "backward"in MPlayer,XMMS etc 2) labeled ">>>" : key code 0x1f, may be used as "forward"... 3) not labeled : key code 0x0a, may be used as "pause"... Once have added these code definitions to the kernel, me got all these operations available for viewing movies & listening music.

| | | | | | | | | | | | | | | | | | | | | | Observation one: ->write_proc and ->data assignments aren't needed. Removed. Observation two: codecs lists are unprotected. Patch doesn't fix this. Observation three: /proc/videocodecs printout is done to temporary _global_ buffer which is freed in between. Consequently, two users hitting this file can screwup each other. Steps to reproduce: modprobe videocodec while true; do cat /proc/videocodecs &>/dev/null; done & while true; do cat /proc/videocodecs &>/dev/null; done & The fix is switching to seq_files, this removes code, especially some line-length "logic".

| | | | | | | | | | | | | | | | | | | | | This patch fixes three related issues and a fourth trivial one: - Use buffers even if no-one's currently waiting for them (fixes underrun issues); - Don't return incomplete/mangled frames at the start of streaming and in the case of buffer underruns; - Fix an issue which could cause the driver to write to a buffer that's been freed after videobuf_queue_cancel is called (exposed by the previous two fixes - for some reason, ignoring buffers that weren't being waited on worked around the issue); - Fix a bug which could cause only one field to be filled in the first buffer (or first few buffers) after streaming is started.

* V4L/DVB (7553): videobuf-vmalloc: fix STREAMOFF/STREAMONMauro Carvalho Chehab2008-04-241-9/+27
| | | | | | | | | | | | | | There were a small bug on videobuf-vmalloc that were preventing STREAMOFF to work. The issue is that vmalloc'ed mmaped memory should only be freed after being sure that there aren't any mmap usage. Otherwise, the memory remap will stop working, and the userspace won't receive any frames. This bug were affecting some userspace applications, like tvtime. After this patch, tvtime started to work again with the drivers that use videobuf-vmalloc. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (7552): videbuf-vmalloc: Corrects mmap codeMauro Carvalho Chehab2008-04-242-72/+105
| | | | | | | | | | | | | | | | | | | | | | There were some bugs on videobuf-vmalloc. Basically, remap were called with a wrong parameter. Due to that, a later remap were needed, generating the need of some hacks on videobuf-vmalloc and videobuf-core. This patch fixes the remap and removes the hacks. TODO: - V4L2_MEMORY_USERPTR is not implemented yet. This method should be properly implemented, in order to work with a few userspace applications. - The driver also doesn't implement V4L2_MEMORY_OVERLAY. This method is used only by a few applications, and are becaming obsolete, due to the increment of cpu performance. So, most apps prefer to retrieve data to an internal buffer, doing some processing like de-interlacing. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

| | | | | | | | | | | | | | | - 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.

* V4L/DVB (7538): Adds selectable adapter numbers as per module optionJanne Grunau2008-04-2437-83/+242
| | | | | | | | | | | | | | | | | | | | 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.
