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 <andrey.grodzovsky@amd.com> --- drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 4 ++-- drivers/gpu/drm/amd/amdgpu/amdgpu_gart.c | 14 +------------- drivers/gpu/drm/amd/amdgpu/amdgpu_gart.h | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_ih.c | 6 ++++-- drivers/gpu/drm/amd/amdgpu/amdgpu_irq.c | 5 +++++ drivers/gpu/drm/amd/amdgpu/cik_ih.c | 1 - drivers/gpu/drm/amd/amdgpu/cz_ih.c | 1 - drivers/gpu/drm/amd/amdgpu/gmc_v10_0.c | 1 - drivers/gpu/drm/amd/amdgpu/gmc_v6_0.c | 1 - drivers/gpu/drm/amd/amdgpu/gmc_v7_0.c | 1 - drivers/gpu/drm/amd/amdgpu/gmc_v8_0.c | 1 - drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c | 1 - drivers/gpu/drm/amd/amdgpu/iceland_ih.c | 1 - drivers/gpu/drm/amd/amdgpu/navi10_ih.c | 4 ---- drivers/gpu/drm/amd/amdgpu/si_ih.c | 1 - drivers/gpu/drm/amd/amdgpu/tonga_ih.c | 1 - drivers/gpu/drm/amd/amdgpu/vega10_ih.c | 4 ---- drivers/gpu/drm/amd/amdgpu/vega20_ih.c | 4 ---- 18 files changed, 13 insertions(+), 40 deletions(-)
