Hi Christian and Amaranath,

Introduce tests for ttm_bo_validate()/ttm_bo_init_validate() that exercise
simple BO placement as well as eviction (including the case where the evict
domain also requires eviction to fit the incoming buffer). Prepare KUnit
helpers to handle such scenarios and add a mock VRAM manager. This series also
includes some updates to the helpers and more definitions used to define
"special" memory domains (e.g., one that can't allocate resources or is busy),
as well as drive-by fixes for the tests.
There are a couple of areas in which this test suite can be improved.
Suggestions for future work can be found in the TODO file.
Use kunit_tool script to manually run all the tests:
$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm/ttm/tests
I collected r-bs for all patches in the series, they apply cleanly on the top of drm-misc and drm-tip and all the tests pass[1]. Would it be possible to merge them?
In other news, we enabled TTM KUnit tests in CI for Xe driver, the results can be seen on patchwork. For example:
https://patchwork.freedesktop.org/series/134956/
(see CI.KUnit step)
All the best,
Karolina
