drm/xe/kunit: Fix forcewake assertion in mocs test

2025-11-18T18:04:48+00:00

The MOCS kunit test calls KUNIT_ASSERT_TRUE_MSG() with a condition of 'true;' this prevents the assertion from ever failing. Replace KUNIT_ASSERT_TRUE_MSG with KUNIT_FAIL_AND_ABORT to get the intended failure behavior in cases where forcewake was not acquired successfully.

drm/xe/kunit: Fix kerneldoc for parameterized tests

2025-10-16T05:48:43+00:00

Kunit's generate_params() was recently updated to take an additional test context parameter. Xe's IP and platform parameter generators were updated accordingly at the same time, but the new parameter was not added to the functions' kerneldoc, resulting in the following warnings: Warning: drivers/gpu/drm/xe/tests/xe_pci.c:78 function parameter 'test' not described in 'xe_pci_fake_data_gen_params' Warning: drivers/gpu/drm/xe/tests/xe_pci.c:254 function parameter 'test' not described in 'xe_pci_graphics_ip_gen_param' Warning: drivers/gpu/drm/xe/tests/xe_pci.c:278 function parameter 'test' not described in 'xe_pci_media_ip_gen_param' Warning: drivers/gpu/drm/xe/tests/xe_pci.c:302 function parameter 'test' not described in 'xe_pci_id_gen_param' Warning: drivers/gpu/drm/xe/tests/xe_pci.c:390 function parameter 'test' not described in 'xe_pci_live_device_gen_param' 5 warnings as errors Document the new parameter to eliminate the warnings and make CI happy.

These methods present limitations when dealing with dynamically generated parameter arrays, or in scenarios where populating parameters sequentially via generate_params() is inefficient or overly complex.

drm/xe/tests: Add pre-GMDID IP descriptors to param generators

Recently introduced kunit parameter generators were based on the existing arrays which have only GDMID-based IPs and didn't take into account IP definitions from pre-GMDID era.
