[PATCH v3 0/2] [media] videobuf2-dc: Add support for cacheable MMAP

Show all headers | View raw

Hi,

This series adds support for cacheable MMAP in DMA coherent allocator.

The first patch moves the vb2_dc_get_base_sgt() function above mmap
callbacks for calls introduced by the second patch. This avoids a
forward declaration.

Changes in v2:
- Put function move in a separate patch
- Added comments

Changes in v3:
- Remove redundant test on NO_KERNEL_MAPPING DMA attribute in mmap()
