Ask from kernel about supported modes for each plane and try setting
them on display and verify functionality with crc.

DRM_FORMAT_ARGB8888 and DRM_FORMAT_ABGR8888 skip crc testing on
primary and overlay planes because they produce incorrect crcs from
hardware. DRM_FORMAT_ARGB8888 is tested on cursor plane.

v3: address review comments from Mika Kahola.
Stop crc at end of test before freeing it. Use libdrm instead
of mixing ioctl and libdrm.

v2: Address review comments from Mika Kahola.
Keep crc running for all tests while on same pipe, set tile height
to 16 and read only one crc per test.

I didn't go adding igt_exit() at the end of the test because I use igt_main
which will do igt_exit() for me.

Ask from kernel about supported modes for each plane and try setting
them on display and verify functionality with crc.

DRM_FORMAT_ARGB8888 and DRM_FORMAT_ABGR8888 skip crc testing on
primary and overlay planes because they produce incorrect crcs from
hardware. DRM_FORMAT_ARGB8888 is tested on cursor plane.

v2: Added support for planar formats.

v3: Address review comments from Mika Kahola.
Keep crc running for all tests while on same pipe, set tile height
to 16 and read only one crc per test.

* [igt-dev] [PATCH i-g-t] tests/kms_available_modes_crc: Test all modes on all planes
@ 2018-03-16 13:39 Juha-Pekka Heikkila

From: Juha-Pekka Heikkila @ 2018-03-16 13:39 UTC (permalink / raw)
  To: igt-dev

Ask from kernel about supported modes for each plane and try setting
them on display and verify functionality with crc.

DRM_FORMAT_ARGB8888 and DRM_FORMAT_ABGR8888 skip crc testing on
primary and overlay planes because they produce incorrect crcs from
hardware. DRM_FORMAT_ARGB8888 is tested on cursor plane.

* [igt-dev] [PATCH i-g-t] tests/kms_available_modes_crc: Test all modes on all planes

Ask from kernel about supported modes for each plane and try setting
them on display and verify functionality with crc.

DRM_FORMAT_ARGB8888 and DRM_FORMAT_ABGR8888 skip crc testing on
primary and overlay planes because they produce incorrect crcs from
hardware. DRM_FORMAT_ARGB8888 is tested on cursor plane.

There is preparation for planar formats but I didn't see stable
implementation yet so it has holes.

This is tested on HSW and SKL. There are pieces to support NV12 but it was
not succesfully tested anywhere, probably need work still.
