Fix some issues regarding retry fault handling,
such as enabling the retry fault interrupt (necessary
for retry faults to work) and similar.
Improve retry faults on Navi 3 dGPUs by enabling
the filter CAM, which can filter the repeated page
fault interrupts that happen when retry faults are
enabled, making the handling more efficient.
With this series, the kernel is able to mitigate
most page faults on Navi 3 without causing a hang
and without a need to reset the GPU, when the
amdgpu.noretry=0 module parameter is set.
Changes in v2:
* Reordered patches in the series to put bug fixes first
* Enable retry fault interrupt in init_system_aperture_regs()
instead of in set_fault_enable_default()
* Added a patch to respect the noretry flag on GFX12.1 too
Timur Kristóf (7):
drm/amdgpu: Use gmc->noretry instead of amdgpu_noretry directly
drm/amdgpu/gfxhub: Program CRASH_ON_*_FAULT bits to 0 as needed
drm/amdgpu/gmc: Don't compare page fault timestamps with other
interrupts
drm/amdgpu/ih: Add retry_cam_ack IH function pointer
drm/amdgpu/gfxhub: Enable retry fault interrupts when needed
drm/amdgpu/gfxhub: Respect noretry flag for retry faults on GFX12.1
drm/amdgpu: Enable retry CAM on Navi 3 dGPUs
