drm/amdgpu: Fix error handling in amdgpu_ras_add_bad_pages

2025-01-06T19:44:28Z

It ensures that appropriate error codes are returned when an error condition is detected Fixes the below; drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c:2849 amdgpu_ras_add_bad_pages() warn: missing error code here? 'amdgpu_umc_pages_in_a_row()' failed. drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c:2884 amdgpu_ras_add_bad_pages() warn: missing error code here? 'amdgpu_ras_mca2pa()' failed. v2: s/-EIO/-EINVAL, retained the use of -EINVAL from amdgpu_umc_pages_in_a_row & and amdgpu_ras_mca2pa_by_idx, when the RAS context is not initialized or the convert_ras_err_addr function is unavailable. (Thomas) V3: Returning 0 as the absence of eh_data is acceptable.

drm/amdgpu: correct the calculation of RAS bad page

2024-12-10T15:26:51Z

After the introduction of NPS RAS, one bad page record on eeprom may be related to 1 or 16 bad pages, so the bad page record and bad page are two different concepts, define a new variable to store bad page number. Signed-off-by: Tao Zhou Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: parse legacy RAS bad page mixed with new data in various NPS modes

2024-12-10T15:26:48Z

All legacy RAS bad pages are generated in NPS1 mode, but new bad page can be generated in any NPS mode, so we can't use retired_page stored on eeprom directly in non-nps1 mode even for legacy data. We need to take different actions for different data, new data can be identified from old data by UMC_CHANNEL_IDX_V2 flag.
