2018-02-26drm/amdgpu: use the TTM dummy page instead of allocating oneChristian König1-1/+1
We have a global dummy page in TTM, use that one instead of allocating a new one. Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

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.

2017-03-29drm/amdgpu/ih: store the full context idAlex Deucher1-1/+1
The contextID field (formerly known as src_data) of the IH vector stores client specific information about an interrupt. It was expanded from 32 bits to 128 on newer asics. Expand the src_id field to handle this.
