Fix system hang while entering suspend with AMD Navi3x graphics

[Chris Chiu]

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.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-oem-6.5/6.5.0-1023.24 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-oem-6.5' to 'verification-done-jammy-linux-oem-6.5'. If the problem still exists, change the tag 'verification-needed-jammy-linux-oem-6.5' to 'verification-failed-jammy-linux-oem-6.5'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
