That's just a leftover from old radeon days and was preventing CS and GART
bindings before the hardware was initialized. But nowdays that is
perfectly valid.

The only thing we need to warn about are GART binding before the table
is even allocated.

Don't flush gart changes after recovering each BO instead
do it after recovering all the BOs. Flishing gart also needed
for amdgpu_ttm_alloc_gart().

v4: use containerof to retrieve adev struct.
v3: rename amdgpu_gart_tlb_flush() -&gt; amdgpu_gart_invalidate_tlb().
v2: abstract out gart tlb flushing logic to amdgpu_gart.c

<title>drm/amdgpu: Handle IOMMU enabled case.</title>

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-&gt;ring)
to avoid freeing uniniitalized rings.
Call amdgpu_ih_ring_fini unconditionally.
v8: Add deatiled explanation
