[PATCH v13 01/12] drm/ttm/tests: Fix a warning in ttm_bo_unreserve_bulk

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



BOs in a bulk move have to share the same reservation object. That is
not the case in the ttm_bo_unreserve_bulk subtest. Update
ttm_bo_kunit_init() helper to accept dma_resv object so we can define
buffer objects that share the same resv. Update calls to that helper
accordingly.

Fixes: 995279d280d1 ("drm/ttm/tests: Add tests for ttm_bo functions")
