include/media/media-entity.h: replace kernel.h with the necessary inclusions

2021-11-09T18:02:49+00:00

When kernel.h is used in the headers it adds a lot into dependency hell,
especially when there are circular dependencies are involved.

Replace kernel.h inclusion with the list of what is really being used.

media: v4l2-dev.h: move open brace after struct video_device

2021-10-05T07:37:21+00:00

The open brace should be after a struct of define, that's good
for searching.

media: videobuf2: add queue memory coherency parameter

2021-09-30T08:07:57+00:00

Preparations for future V4L2_MEMORY_FLAG_NON_COHERENT support.

Extend the vb2_core_reqbufs() parameters list to accept requests'
->flags, which will be used for memory coherency configuration.

An attempt to allocate a buffer with coherency requirements
that do not match the queue's consistency model will fail.

media: videobuf2: inverse buffer cache_hints flags

2021-09-30T08:07:56+00:00

It would be less error prone if the default cache hints value
(we kzalloc() structs, so it's zeroed out by default) would be
to "always sync/flush" caches. Inverse and rename cache hints
flags.

media: videobuf2: rework vb2_mem_ops API

2021-09-30T08:07:56+00:00

With the new DMA API we need an extension of the videobuf2 API.
Previously, videobuf2 core would set the non-coherent DMA bit
in the vb2_queue dma_attr field (if user-space would pass a
corresponding memory hint); the vb2 core then would pass the
vb2_queue dma_attrs to the vb2 allocators. The vb2 allocator
would use the queue's dma_attr and the DMA API would allocate
either coherent or non-coherent memory.

But we cannot do this anymore, since there is no corresponding DMA
attr flag and, hence, there is no way for the allocator to become
aware of what type of allocation user-space has requested. So we
need to pass more context from videobuf2 core to the allocators.

Fix this by changing the call_ptr_memop() macro to pass the
vb2 pointer to the corresponding op callbacks.

2021-09-30T08:07:35+00:00

Rename V4L2 async notifier functions, replacing "notifier" with "nf" and
removing "_subdev" at the end of the function names adding subdevs as you
can only add subdevs to a notifier. Also wrap and otherwise clean up long
lines.
