[PATCH v8 0/4] tests/kms_async_flips: Create subtest for overlay planes

[André Almeida]

This patchset creates a subtest for overlay planes. This is supported by amdgpu
and is merged in the kernel:

https://lore.kernel.org/lkml/173948734065.719858.7405160715916126757.b4-ty@linaro.org/

v8:
 - Make "Async page flip" name consistent in patch 1
 - Clarify documentation about asserting with a bad fd in igt_has_drm_cap()

v7:
 - igt_has_drm_cap() asserts only if it was a bad fd. The rest is up to the
 caller to assert or require.
 - we now have different errors for when the cap is not supported by the driver,
 and when the cap doesn't exist in the kernel

v6:
 - Added missing `test_init_ops()` for "overlay-atomic" test
 - Reworked `test_init_fbs()`: it destroys all buffers when the modifier
 changes, and recreate then if they are need for the next test. It also destroys
 overlay buffers if they are not needed anymore

v5:
 - Added a new patch "lib/ioctl_wrappers: let the caller handle capability check
   result" by Melissa Wen
 - This patch solved an issue that the test was exiting instead of skipping when
   the driver did not support ATOMIC_ASYNC_PAGE_FLIP
 - test_finish() is now called test_init_ops() and is called in the beginning of
   every test. This was done because some asserts prevented the test to reach
   the final of the run_test() function.
 - Fixed a typo to correctly set the overlay fb to the overlay plane
 - Added code to remove the overlay fb by the end of the test
 - Fixed a bug that test_init_fbs() was skipping the fb creation for overlay
   planes
 - Fixed require_overlay_flip_support() by changing the fb to be flipped with
   the async flip

v4:
 - Created a patch to check for DRM_CAP_ATOMIC_ASYNC_PAGE_FLIP, so drivers
 without support for it, skips instead of failing (Melissa)
 - Encapsulated all test paths options into a function to easy maintenance (Melissa)
 - Brought back test description for GitLab compilation

v3:
 - Fixed a bug that was mixing `alternate_sync_async = true` with the overlay path
 - Refactored how the test parameters are being set/unset (patch 1/2)
 - Fixed a bug where a primary buffer was being used with an overlay plane

v2: Add test description for GitLab compilation
