This patch adds support for DMABUF memory type in videobuf2. It calls relevant
APIs of dma_buf for v4l reqbuf / qbuf / dqbuf operations.
For this version, the support is for videobuf2 as a user of the shared buffer;
so the allocation of the buffer is done outside of V4L2. [A s
Hello everyone,
This patchset adds support for DMABUF [2] importing to V4L2 stack.
The support for DMABUF exporting was moved to separate patchset
due to dependency on patches for DMA mapping redesign by
Marek Szyprowski [4].
v6:
- fixed missing entry in v4l2_memory_names
- fixed a bug occuring af
From: Sumit Semwal
Adding DMABUF memory type causes videobuf to complain about not using it
in some switch cases. This patch removes these warnings.

vb2-dma-contig returns a vb2_dc_conf structure instance as the vb2
allocation context. That structure only stores a pointer to the physical
device. Remove it and use the device pointer directly as the allocation
context.

If it still happens with a 3.3 or 3.4 kernel, can you bisect?

I only see this with the LLVM compiler, the old one seems fine. There is a
texture flickering on some surfaces, but that affects both of them (I use the
level Q1DM6 for testing).
Yes, I use a
