From c84d46707ebbfc303268e27d5aeb8bb4e6d5b1ff Mon Sep 17 00:00:00 2001 From: Guchun Chen Date: Wed, 22 Jul 2020 10:00:27 +0800 Subject: drm/amdgpu: validate bad page threshold in ras(v3) Bad page threshold value should be valid in the range between -1 and max records length of eeprom. It could determine when saved bad pages exceed threshold value, and proceed corresponding actions. v2: When using the default typical value, it should be min value between typical value and eeprom max records length. v3: drop the case of setting bad_page_cnt_threshold to be 0xFFFFFFFF, as it confuses user.
