drm/amdgpu: Handle IOMMU enabled case.

2021-05-20T03:50:27+00:00

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 Signed-off-by: Andrey Grodzovsky Reviewed-by: Felix Kuehling Link: https://patchwork.freedesktop.org/patch/msgid/20210517143851.475058-1-andrey.grodzovsky@amd.com

drm/amdgpu: Split amdgpu_device_fini into early and late

2021-05-20T03:45:49+00:00

Some of the stuff in amdgpu_device_fini such as HW interrupts disable and pending fences finilization must be done right away on pci_remove while most of the stuff which relates to finilizing and releasing driver data structures can be kept until drm_driver.release hook is called, i.e. when the last device reference is dropped. v4: Change functions prefix early->hw and late->sw Signed-off-by: Andrey Grodzovsky Acked-by: Christian König Reviewed-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20210512142648.666476-3-andrey.grodzovsky@amd.com
