From 8483fdfea778aedded76c74659692dee3756b12b Mon Sep 17 00:00:00 2001 From: Kent Russell Date: Tue, 12 Oct 2021 16:49:24 -0400 Subject: [PATCH] drm/amdgpu: Warn when bad pages approaches 90% threshold dmesg doesn't warn when the number of bad pages approaches the threshold for page retirement. WARN when the number of bad pages is at 90% or greater for easier checks and planning, instead of waiting until the GPU is full of bad pages.
