Bug description:
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.
[Fix]
Add release FW binary from AMD to linux-firmware
dcn_3_2_0_dmcub.bin for Navi31 and 32:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/amdgpu/dcn_3_2_0_dmcub.bin?id=eb06e8bbe56cea19b8c2a23c154e2dcefd79fa47
[git.kernel.org]
dcn_3_2_1_dmcub.bin for Navi33:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/amdgpu/dcn_3_2_1_dmcub.bin?id=8b8ac15f9bce35d555b8253156053a7e2b661f6a
[git.kernel.org]
[Test Case]
1. Install AMD W7500/W7600/W7700 graphics
2. Test with latest linux kernel and linux-firmware
3. Running fwts s3 stress test to check if system hangs
[Where problems could occur]
The dcn_3_2_0_dmcub only for Navi31 and dcn_3_2_1_dmcub only for Navi33. The
impact are restricted to particular series.
