2008-07-27saa7146: fix read from uninitialized memoryHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The offset field of the scatterlist entry *after* the last valid scatterlist entry was used instead of the first scatterlist entry (as was the intention of this code). This worked fine until the kzalloc of the sglist was replaced with kmalloc and sg_init_table only zeroed the exact needed length. Apparently kzalloc zeroes a bit more than is strictly necessary so the offset field was always 0 in the past. But now the offset field was suddenly random and this led to broken captures.

2008-07-26saa7146: fix VIDIOC_ENUM_FMTHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> VIDIOC_ENUM_FMT should keep the index and type fields. Instead, type was zeroed. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

From: Mauro Carvalho Chehab <mchehab@infradead.org> Due to the feedback I got, I've changed the -git patch. This needs to be reflected also at -hg tree. kernel-sync: Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-26From: Mauro Carvalho Chehab <mchehab@infradead.org>Mauro Carvalho Chehab
Move tuners to common/tuners There were several issues in the past, caused by the hybrid tuner design, since now, the same tuner can be used by drivers/media/dvb and drivers/media/video. This patch moves those common tuners into a common dir. It also moves saa7146 driver into drivers/media/video, where other hybrid drivers are placed. Kconfig items were rearranged, to split V4L/DVB core from their drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

Subject: Convert videobuf-dma-sg to generic DMA API Date: Tue, 19 Feb 2008 13:40:54 +0100 (CET) videobuf-dma-sg does not need to depend on PCI. Switch it to using generic DMA API, convert all affected drivers, relax Kconfig restriction, improve compile-time type checking, fix some Coding Style violations while at it.

2007-11-13V4L: videobuf-core locking fixes and commentsBrandon Philips
- Add comments to functions that require that caller hold q->lock - Add __videobuf_mmap_free that doesn't hold q->lock for use within videobuf - Add locking to videobuf_mmap_free - Fix linux/drivers/media/common/saa7146_video.c which was holding lock around videobuf_read_stop - Add locking to functions that operate on a queue - Add videobuf_stop to take care of stopping in both the read and stream case TODO: bttv still has an unsafe call to videobuf_queue_is_busy Signed-off-by: Brandon Philips <bphilips@suse.de>

2007-10-05 V4L: videobuf-core.c avoid NULL dereferences in videobuf-coreMauro Carvalho Chehab
From: Brandon Philips <bphilips@suse.de> The return value of videobuf_alloc() is unchecked but this function will return NULL on an error. Check for NULL and make videobuf_reqbufs() return the number of successfully allocated buffers. Also, fix saa7146_video.c and bttv-driver.c to use this returned buffer count. Tested against the vivi driver. Not tested against saa7146 or bt8xx devices. Signed-off-by: Brandon Philips <bphilips@suse.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-08-23Adapt drivers to use the newer videobuf modulesMauro Carvalho Chehab
PCI-dependent videobuf_foo methods were renamed as videobuf_pci_foo. Also, videobuf_dmabuf is now part of videobuf-dma-sg private struct. So, to access it, a subroutine call is needed. This patch renames all occurences of those function calls to be consistent with the video-buf split.

2007-02-19compat: Add -include linux/version.h to cflagsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Add -include linux/version.h to the cflags. Now code can have backward compatibility test without including compat.h first. Linux headers included from compat.h are removed, so that code will get the same headers when compiling in v4l-dvb as it does in the kernel. Many drivers have compat.h moved to the end of their include list, as this lets compat.h do things it can't do at the beginning. Such as test of something is defined to include compat code, or to put a wrapper around a function without changing the function's name. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

2006-03-10Make video_buf more genericMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Video_buf were concerned to allow PCI devices to be used as video capture devices. This patch extends video_buf features by virtualizing pci-dependent functions and allowing other type of devices to use it. It is still DMA centric, although it may be used also by devices that emulates scatter/gather behavior or a DMA device Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
