Subject: [PATCH v6 06/16] drm/amdgpu: Handle IOMMU enabled case.
Date: Mon, 10 May 2021 12:36:15 -0400	[thread overview]
Message-ID: <20210510163625.407105-7-andrey.grodzovsky@amd.com> (raw)
In-Reply-To: <20210510163625.407105-1-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
