[PATCH v2 0/5] Implement CRC and Add necessary infrastructure

[Haneen Mohammed]

This patchset implement CRC debugfs API and add the necessary
infrastructure required to enable to compute and add CRCs entries.

1. add functions to map/unmap 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 with
appropriate synchronization methods.

Haneen Mohammed (5):
  drm/vkms: Add functions to map/unmap GEM backing storage
  drm/vkms: map/unmap buffers in [prepare/cleanup]_fb hooks
  drm/vkms: Add atomic_helper_check_plane_state
  drm/vkms: subclass CRTC state
  drm/vkms: Implement CRC debugfs API
