2007-10-08Fix: avoid oops on some SMP machinesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> This workaround fix a bug that happens on some SMP machines. On those machines, videobuf_iolock is called too soon, before file .mmap handler. This patch calls the scheduler before iolocking, allowing it to properly call the pending mmap. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-08remove videobuf_set_pci_opsMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Before the videobuf redesign, a procedure for re-using videobuf without PCI scatter/gather where provided by changing the pci-dependent operations by other operations. With the newer approach, those methods are obsolete and can safelly be removed. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-10-04cx23885: Update to new videobuf codeTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> cx23885 was still uses the old video-buf includes and code, which would only `work' if one happened to be compiling against a kernel that had the old headers. Even then, it wouldn't actually work, it would just compile without errors. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2007-10-04videobuf: Remove references to old Kconfig option nameTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> CONFIG_VIDEO_BUF_DVB became CONFIG_VIDEOBUF_DVB. But in these cases, it makes more sense to use CONFIG_VIDEO_SAA7134_DVB or CONFIG_VIDEO_CX88_DVB_MODULE depending on the driver. The reference in cx23885.h should just be removed, as the code there needs to be included if DVB is on or off. I do not think you can even compile the cx23885 driver without DVB. It's clearly just leftover from when the file was obvious copied from the cx88 driver (which is not mentioned in the copyright BTW). Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

The "resource" locking in vivi isn't needed since streamon/streamoff/read_stream do mutual exclusion using q->reading/q->streaming.

2007-08-27Fix vivi poll() methodMauro Carvalho Chehab
Due to the replace of videobuf_read_one to videobuf_read_stream, poll() method implementation is wrong. This fixes poll() implementation, making read of /dev/video? to work again.

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.

2007-08-23Replace video-buf to a more generic approachMauro Carvalho Chehab
video-buf currently does two different tasks: - Manages video buffers with a common code that allows implementing all the V4L2 different modes of buffering; - Controls memory allocations While the first task is generic, the second were written to support PCI DMA Scatter/Gather needs. The original approach can't even work for those video capture hardware that don't support scatter/gather. I did one approach to make it more generic. While the approach worked fine for vivi driver, it were not generic enough to handle USB needs. This patch creates two different modules, one containing the generic video buffer handling (videobuf-core) and another with PCI DMA S/G. After this patch, it would be simpler to write an USB video-buf and a non-SG DMA module.
