* drm/amdgpu: Add check to prevent IH overflowDefang Bo2021-01-051-13/+24
| | | | | | | | | | | | | | | 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.

* drm/amdgpu: Handle GPUVM fault stormsFelix Kuehling2017-09-281-2/+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.
