[igt-dev] [PATCH i-g-t v2 00/12] Chamelium VC4 plane testing, with T-tiled mode

[Paul Kocialkowski]

This series introduces the required plumbing for allocating buffers in
the VC4 T-tiled mode and converting to that mode from XR24 linear
buffers.

With that in place, a new Chamelium test is introduced to perform some
testing of planes with randomized properties. It also tests the
VC4-specific VC4-specific T-tiled mode.

This series is based on Maxime Ripard's series:
  igt: chamelium: Test YUV buffers using the Chamelium

Changes since v1:
* Added collected Reviewed-by tags;
* Removed explicit size and constified tiling read order tables;
* Removed unnecessary MAP_FAILED addition in map_bo;
* Added pipe and output helpers to count and iterate planes of a given type;
* Moved CRC debug prints to the chamelium library;
* Fixed destination stride description for igt_fb_convert_with_stride;
* Split planes test into a few sub-routines;
* Removed explicit underrun detection since general error reporting is enough;
* Removed underrun detection bits due to ongoing Chamelium-specific issues;
* Deconfigured planes before removing their framebuffer, avoiding kmsg errors.
