2021-05-19drm/amdgpu: Handle IOMMU enabled case.Andrey Grodzovsky1-1/+0
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.

2021-01-05drm/amdgpu: Add check to prevent IH overflowDefang Bo1-13/+23
Similar to commit <b82175750131>("drm/amdgpu: fix IH overflow on Vega10 v2"). When an ring buffer overflow happens the appropriate bit is set in the WPTR register which is also written back to memory. But clearing the bit in the WPTR doesn't trigger another memory writeback. So what can happen is that we end up processing the buffer overflow over and over again because the bit is never cleared. Resulting in a random system lockup because of an infinite loop in an interrupt handler.

2017-09-28drm/amdgpu: Handle GPUVM fault stormsFelix Kuehling1-2/+17
When many wavefronts cause VM faults at the same time, it can overwhelm the interrupt handler and cause IH ring overflows before the driver can notify or kill the faulting application. As a workaround I'm introducing limited per-VM fault credit. After that number of VM faults have occurred, further VM faults are filtered out at the prescreen stage of processing. This depends on the PASID in the interrupt packet, so it currently only works for KFD contexts.
