2025-04-12drm/amdgpu: Direct ret in ras_reset_err_cnt on VFEllen Pan1-0/+3
With adding sriov_vf check, we directly return EOPNOTSUPP in ras_reset_error_count as we should not do anything on VF to reset RAS error count. This also fixes the issue that loading guest driver causes register violations.

When ACA is enabled, an unusable aca_sysfs is created rather than amdgpu_ras_sysfs_create() Likewise, VFs depend on host support to query CPERs, rather than ACA component.

2024-12-10drm/amdgpu: Prefer RAS recovery for scheduler hangLijo Lazar1-2/+53
Before scheduling a recovery due to scheduler/job hang, check if a RAS error is detected. If so, choose RAS recovery to handle the situation. A scheduler/job hang could be the side effect of a RAS error. In such cases, it is required to go through the RAS error recovery process. A RAS error recovery process in certains cases also could avoid a full device device reset. An error state is maintained in RAS context to detect the block affected. Fatal Error state uses unused block id. Set the block id when error is detected. If the interrupt handler detected a poison error, it's not required to look for a fatal error. Skip fatal error checking in such cases. Signed-off-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

The VF FB access may abruptly end due to a fatal error, therefore the VF must cache and sanitize the input. The Host allows 15 Telemetry messages every 60 seconds, afterwhich the host will ignore any more in-coming telemetry messages.

2024-07-10drm/amdgpu: timely save bad pages to eeprom after gpu ras reset is completedYiPeng Chai1-1/+5
The problem case is as follows: 1. GPU A triggers a gpu ras reset, and GPU A drives GPU B to also perform a gpu ras reset. 2. After gpu B ras reset started, gpu B queried a DE data. Since the DE data was queried in the ras reset thread instead of the page retirement thread, bad page retirement work would not be triggered. Then even if all gpu resets are completed, the bad pages will be cached in RAM until GPU B's bad page retirement work is triggered again and then saved to eeprom.
