From: Luben Tuikov Date: Sat, 3 Jun 2023 04:08:04 +0000 (-0400) Subject: drm/amdgpu: Report ras_num_recs in debugfs X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=740f42a28f4cff9e009a17cc78666165ecca9293;p=linux.git drm/amdgpu: Report ras_num_recs in debugfs Report the number of records stored in the RAS EEPROM table in debugfs. This can be used by user-space to calculate the capacity of the RAS EEPROM table since "bad_page_cnt_threshold" is also reported in the same place in debugfs. See commit 7fb640714547 ("drm/amdgpu: Add bad_page_cnt_threshold to debugfs"). ras_num_recs can already be inferred by dumping the RAS EEPROM table, also in the same debugfs location, see commit reference c65b0805e77919 (drm/amdgpu: RAS EEPROM table is now in debugfs, 2021-04-08). This commit makes it an integer value easily shown in a single file.
