drm/amdgpu: Handle IOMMU enabled case. 2021-05-20T03:50:27+00:00 Andrey Grodzovsky andrey.grodzovsky@amd.com 2021-05-17T14:38:51+00:00 d10d0daa207276aff3b740d1ea9b3f58a63256e7 Problem: Handle all DMA IOMMU group related dependencies before the group is removed. Those manifest themself in that when IOMMU enabled DMA map/unmap is dependent on the presence of IOMMU group the device belongs to but, this group is released once the device is removed from PCI topology.

Problem:
Handle all DMA IOMMU group related dependencies before the
group is removed. Those manifest themself in that when IOMMU
enabled DMA map/unmap is dependent on the presence of IOMMU
group the device belongs to but, this group is released once
the device is removed from PCI topology.

Fix:
Expedite all such unmap operations to pci remove driver callback.

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.
v8: Add deatiled explanation
