[PATCH v7 05/16] drm/amdgpu: Handle IOMMU enabled case.
Andrey Grodzovsky
andrey.grodzovsky at amd.com
Wed May 12 14:26:37 UTC 2021
Handle all DMA IOMMU gropup related dependencies before the
group is removed.
v5: Drop IOMMU notifier and switch to lockless call to ttm_tt_unpopulate
v6: Drop the BO unamp list
v7:
Drop amdgpu_gart_fini
In amdgpu_ih_ring_fini do uncinditional check (!ih->ring)
to avoid freeing uniniitalized rings.
Call amdgpu_ih_ring_fini unconditionally.
