V4L/DVB: v4l videobuf: add videobuf_buffer *buf as argument to mmap_mapper

2010-05-19T15:57:54+00:00

mmap_mapper should operate on a buffer, not on a complete queue. So let
the videobuf-core find the correct buffer instead of duplicating that
code in each mmap_mapper implementation.

The dma-sg implementation has backwards compatibility code for handling
the V4L1_COMPAT layer. This code is now under the v4L1_COMPAT config option.

V4L/DVB: v4l videobuf: move video_copy_to_user and copy_stream to core

2010-05-19T15:57:53+00:00

The video_copy_to_user and copy_stream ops are almost identical for all
videobuf memtype variants. All that is needed is to use the new vaddr
op and these functions can be moved into the core, ensuring we have just
one single implementation instead of three.

V4L/DVB: v4l videobuf: rename videobuf_queue_to_vmalloc to videobuf_queue_to_vaddr

2010-05-19T15:57:52+00:00

Ths function returns the virtual kernel address of the buffer and has
nothing to do with allocation.

V4L/DVB: v4l videobuf: rename .vmalloc to .vaddr

2010-05-19T15:57:52+00:00

Rename the .vmalloc op in struct videobuf_qtype_ops to .vaddr. This op returns
the virtual kernel address of a buffer. vaddr is a lot less confusing than
vmalloc since this callback does do any allocations.

V4L/DVB: v4l videobuf: use struct videobuf_buffer * instead of void * for videobuf_alloc

2010-05-19T15:57:51+00:00

videobuf_alloc() returned a void *. Change to struct videobuf_buffer *
to get better type checking.

V4L/DVB: v4l videobuf: remove mmap_free callback

2010-05-19T15:57:50+00:00

Remove the mmap_free callback from struct videobuf_qtype_ops.

All implementations of this callback do the same trivial check: return
-EBUSY if any buffer is mmapped. That can also be tested in the
videobuf core.

2010-05-19T15:57:50+00:00

The mmap callback in struct videobuf_qtype_ops is never used.
Remove.

V4L/DVB (13377): make struct videobuf_queue_ops constant

2009-12-05T20:41:35+00:00

The videobuf_queue_ops function vector is not declared constant, but
there's no need for the videobuf layer to ever change it.  Make it const
so that videobuf users can make their operations const without warnings.
