2023-06-09drm/amdgpu: Add query_ras_error_count for mmhub v1_8Hawking Zhang1-0/+23
Add query_ras_error_count callback for mmhub v1_8. It will be used to query and log mmhub error count and memory block. Signed-off-by: Hawking Zhang <[email protected]> Reviewed-by: Tao Zhou <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2023-03-13drm/amdgpu: Move mmhub ras block init to ras sw_initHawking Zhang1-0/+2
Initialize mmhub ras block only when mmhub ip block supports ras features. Driver queries ras capabilities after early_init, ras block init needs to be moved to sw_init.

2022-01-14drm/amdgpu: Modify mmhub block to fit for the unified ras block data and opsyipechai1-10/+4
1.Modify mmhub block to fit for the unified ras block data and ops. 2.Change amdgpu_mmhub_ras_funcs to amdgpu_mmhub_ras, and the corresponding variable name remove _funcs suffix. 3.Remove the const flag of mmhub ras variable so that mmhub ras block can be able to be inserted into amdgpu device ras block link list. 4.Invoke amdgpu_ras_register_ras_block function to register mmhub ras block into amdgpu device ras block link list. 5.Remove the redundant code about mmhub in amdgpu_ras.c after using the unified ras block. 5.Remove the redundant code about mmhub in amdgpu_ras.c after using the unified ras block. 6.Fill unified ras block .name .block .ras_late_init and .ras_fini for all of mmhub versions. If .ras_late_init and .ras_fini had been defined by the selected mmhub version, the defined functions will take effect; if not defined, default fill them with amdgpu_mmhub_ras_late_init and amdgpu_mmhub_ras_fini.

2020-09-22drm/amdgpu: update athub interrupt harvesting handleStanley.Yang1-0/+1
GCEA/MMHUB EA error should not result to DF freeze, this is fixed in next generation, but for some reasons the GCEA/MMHUB EA error will result to DF freeze in previous generation, diver should avoid to indicate GCEA/MMHUB EA error as hw fatal error in kernel message by read GCEA/MMHUB err status registers. Changed from V1: make query_ras_error_status function more general make read mmhub er status register more friendly Changed from V2: move ras error status query function into do_recovery workqueue Changed from V3: remove useless code from V2, print GCEA error status instance number Signed-off-by: Stanley.Yang <[email protected]> Reviewed-by: Hawking Zhang <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
