V4L/DVB (6601): V4L: videobuf-core locking fixes and comments

2007-12-11T20:08:08+00:00

- 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

V4L/DVB (6495): saa7146: saa7146_wait_for_debi_done fixes

2007-11-04T23:41:23+00:00

Two fixes for the 'saa7146_wait_for_debi_done' code:
(a) Timeout did not work when the routine was called with
    interrupts disabled.
(b) Reduce PCI I/O load caused by saa7146_wait_for_debi_done.
    Seems to be very important on fast machines!

Based on code posted by Hartmut Birr @vdr-portal.

SG: Change sg_set_page() to take length and offset argument

2007-10-24T09:20:47+00:00

Most drivers need to set length and offset as well, so may as well fold
those three lines into one.

Add sg_assign_page() for those two locations that only needed to set
the page, where the offset/length is set outside of the function context.

Convert files to UTF-8 and some cleanups

2007-10-19T21:21:04+00:00

* Convert files to UTF-8.

  * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

  * Correct town names (Goettingen -> Göttingen)

  * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

V4L/DVB (6305): V4L: videobuf-core.c avoid NULL dereferences in videobuf-core

2007-10-10T03:03:20+00:00

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.

V4L/DVB (6252): Adapt drivers to use the newer videobuf modules

2007-10-10T01:14:55+00:00

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.
