Please attach your full dmesg outputs. Can you bisect? Created attachment 298009 [details]

(In reply to Alex Deucher from comment #2) > Please attach your full dmesg outputs. Can you bisect? Done. Unfortunately no: I’ve never done so before, so while I expect to be technically able to do it, I guess it will take some time for me to setup (I have never compiled a kernel myself either), and time is something I definitively lack of currently (several deadlines to meet each week until the end of August). Since I can live with a 5.12 kernel (or even 5.10 LTS), I’m fine with it having to wait until I have time to setup bisecting if need be though. So while I still don’t have time to setup bisecting, I’m now affected even on LTS kernel. Also, I’ve been in touch with other users having a similar laptop (the XPS version instead of the Precision, but still KabyLake-G), and they don’t seem affected. Thus I’m not sure anymore this is a kernel issue (and whether BOCO vs ATPX is relevant). Where should I seek for guidance in understanding why my dGPU stays stuck in D0 instead of going into D3? Is this or https://gitlab.freedesktop.org/drm/amd and appropriate place? Closing this old bug, this seems gone now on newer kernels. |
Created attachment 298003 [details] amdgpu dmesg output on 5.12 After upgrading to kernel 5.13.4 (from 5.12.15, on Arch Linux), I’ve realized my AMD dGPU was not powering off anymore resulting in increased power consumption, heat and noise (because of the fan trying to dissipate the heat). I’ve compared kernel dmesg on both kernels, and I’ve found related differences: @@ -1,4 +1,6 @@ [drm] amdgpu kernel modesetting enabled. +amdgpu: CRAT table not found +amdgpu: Virtual CRAT table created for CPU amdgpu: Topology: Add CPU node fb0: switching to amdgpudrmfb from EFI VGA amdgpu 0000:01:00.0: enabling device (0006 -> 0007) @@ -14,7 +16,10 @@ amdgpu 0000:01:00.0: amdgpu: GART: 256M 0x000000FF00000000 - 0x000000FF0FFFFFFF [drm] amdgpu: 4096M of VRAM memory ready [drm] amdgpu: 4096M of GTT memory ready. amdgpu: hwmgr_sw_init smu backed is vegam_smu +kfd kfd: amdgpu: Allocated 3969056 bytes on gart +amdgpu: Virtual CRAT table created for GPU amdgpu: Topology: Add dGPU node [0x694f:0x1002] +kfd kfd: amdgpu: added device 1002:694f amdgpu 0000:01:00.0: amdgpu: SE 4, SH per SE 1, CU per SH 6, active_cu_number 20 -amdgpu 0000:01:00.0: amdgpu: Using ATPX for runtime pm -[drm] Initialized amdgpu 3.40.0 20150101 for 0000:01:00.0 on minor 1 +amdgpu 0000:01:00.0: amdgpu: Using BOCO for runtime pm +[drm] Initialized amdgpu 3.41.0 20150101 for 0000:01:00.0 on minor 1 I’ve attached both excerpt matching the diff above.
