Cover letter [RFC 0/3] Add infrastructure for CRC support
This patchset add the necessary infrastructure required to enable to compute and add CRCs entries.
1. add functions to map buffers to kernel address space.
2. map/unmap buffers in the prepare/cleanup_fb hooks.
3. compute crc using crc32 on the visible portion of the buffer.
Note:
This patchset was built on top of the following patch:
subject: "drm/vkms: Add vblank events simulated by hrtimers"
Haneen Mohammed (3):
