Public bug reported: SRU Jusitification for Kernel
[Impact] The system with AMD W7500/W7600/W7700 graphics will randomly hang when entering suspend. The page fault would keep happening and the system can't handle other tasks. BUG: unable to handle page fault for address: 000000000a980148 [Fix] Backport the fix from upstream drm/amdgpu: skip to program GFXDEC registers for suspend abort · torvalds/linux@0326de4 · GitHub drm/amdgpu: Reset dGPU if suspend got aborted · torvalds/linux@8b2be55 · GitHub https://patchwork.freedesktop.org/patch/590570/ [patchwork.freedesktop.org] [Test Case] 1. Install AMD W7500/W7600/W7700 graphics 2. Install latest firmware with dcn_3_2_0_dmcub.bin for Navi31 and 32 and dcn_3_2_1_dmcub.bin for Navi33. 3. Running fwts s3 stress test to check if system hangs [Where problems could occur] Improve the error handling when suspend and add the fallback mechanism in MES engine. Only observed on particular AMD models. Need to test w/ more combinations ========================================================================================= SRU Jusitification for linux-firmware [Impact] The system will randomly hang due to page fault while suspending.
