Subject: [PATCH v7 05/16] drm/amdgpu: Handle IOMMU enabled case.
Date: Wed, 12 May 2021 10:26:37 -0400 [thread overview]
Message-ID: <20210512142648.666476-6-andrey.grodzovsky@amd.com> (raw)
In-Reply-To: <20210512142648.666476-1-andrey.grodzovsky@amd.com>
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.
