drm/amdgpu: Handle GPUVM fault storms

2017-09-28T20:03:30Z

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. Signed-off-by: Felix Kuehling Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Track pending retry faults in IH and VM (v2)

2017-09-26T18:53:20Z

IH tracks pending retry faults in a hash table for fast lookup in interrupt context. Each VM has a short FIFO of pending VM faults for processing in a bottom half. The IH prescreening stage adds retry faults and filters out repeated retry interrupts to minimize the impact of interrupt storms. It's the VM's responsibility remove pending faults once they are handled. For now this is only done when the VM is destroyed. v2: - Made the hash table smaller and the FIFO longer. I never want the FIFO to fill up, because that would make prescreen take longer. 128 pending page faults should be enough to keep migrations busy.

drm/amdgpu: Add PASID management

2017-09-26T17:07:02Z

Allows assigning a PASID to a VM for identifying VMs involved in page faults. The global PASID manager is also exported in the KFD interface so that AMDGPU and KFD can share the PASID space. PASIDs of different sizes can be requested. On APUs, the PASID size is deterined by the capabilities of the IOMMU. So KFD must be able to allocate PASIDs in a smaller range.
