Bug ID: 108940 Summary: drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link. c:1613 core_link_enable_stream+0xc14/0x1040QHD bug? Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: stfn+freedesktop@hijnn.net
Created attachment 142710 --> https://bugs.freedesktop.org/attachment.cgi?id=142710&action=edit 4.19 dmesg crash at boot
I recently switched from a dual monitor setup with 1 HDMI and 1 VGA monitor (connected through a powered HDMI -> VGA concerter) to a QHD 34" Acer ED347CKR monitor (https://www.acer.com/ac/en/US/content/model/UM.CE7AA.001) since Ryzen doesn't VGA (https://bugs.freedesktop.org/show_bug.cgi?id=105880).
It solved that crash, but it introduced a new crash.
4.18 amdgpu.dc_log=1 amdgpu.dc=0 pcie_aspm=off doesn't boot, display corruption. Colored line through boot text 4.19 amdgpu.dc_log=1 amdgpu.dc=0 pcie_aspm=off doesn't boot, display corruption. Colored line through boot text 4.18 amdgpu.dc_log=1 amdgpu.dc=1 crash at boot and systems hangs, see attachment 418_dmesg_boot_crash.log 4.19 amdgpu.dc_log=1 amdgpu.dc=1 crash at boot, system runs, see attachment 419_dmesg_boot_crash.log
All errors below are with 419 amdgpu.dc_log=1 amdgpu.dc=1.
I see a difference in crashes when I boot with my monitor on or off.
Monitor on at boot (419_dmesg_boot_crash.log):

Without pcie_aspm=off my console gets spammed infrequently with errors like:

The first time I saw those was with 4.16, but they don't occur every boot. I'm not sure if those were present <4.16. I'm aslo not sure if this is still present at 4.19. I'll soon find out since my system no longer boots with pci_aspm=off.
When running 4.19 I sometimes see
(EE) AMDGPU(0): drmmode_do_crtc_dpms cannot get last vblank counter
in xorg.log. See 419_Xorg.0.monitor_off_at_boot.log
I tried 4.20rc2 (I can't get newer RC's to build the Manjaro way) but it has identical errors as 4.19.
Also attached lspci -nnk | grep VGA -A 12.

--- Comment #5 from fin4478@hotmail.com --- Manjaro Linux is for Nvidia gpus. For Amd gpus, it has too old kernel and Mesa. Use Debian sid Xfce with a latest custom kernel from kernel.org or https://cgit.freedesktop.org/~agd5f/linux and the Oibaf ppa Mesa bionic version.

--- Comment #14 from H.Habighorst h.habighorst@protonmail.com --- Can confirm.
But I'm a bit worried - there is a part before the "core_link_enable_stream" that seems wrong to me in initializing the device, which seems to occure in all dmesg outputs.
I've attached line numbers via less -N - maybe it helps.
837 [ 8.686299] [drm] BIOS signature incorrect 0 0 838 [ 8.686326] ATOM BIOS: 113-RAVEN-110 839 [ 8.686357] [drm] vm size is 262144 GB, 4 levels, block size is 9-bit, fragment size is 9-bit ... 854 [ 8.688113] [drm] Found VCN firmware Version: 1.73 Family ID: 18 ... 857 [ 8.797714] [drm] DM_PPLIB: values for Invalid clock 858 [ 8.797715] [drm] DM_PPLIB: 0 in kHz 859 [ 8.797715] [drm] DM_PPLIB: 400000 in kHz 860 [ 8.797716] [drm] DM_PPLIB: 933000 in kHz 861 [ 8.797716] [drm] DM_PPLIB: 1067000 in kHz 862 [ 8.797809] WARNING: CPU: 6 PID: 725 at drivers/gpu/drm/amd/amdgpu/../display/dc/calcs/dcn_calcs.c:1380 dcn_bw_update_from_pplib+0x16b/0x280 [amdgpu]
This seems plain wrong to me - shouldn't it mention here the engine clock?
This WARNING stems from not getting the clock values right - seems intended.
The same warning occurs again, I wildly guess for the memory (?!).
Line 862-1017 - only afterwards the mentioned "core_link_enable_stream" bug occurs. It seems to me - as a total layman - that the initialization fails and afterwards bogus happens.

It still happens in latest GIT.

--- Comment #17 from Stefan stfn+freedesktop@hijnn.net --- Still present in 4.20.12, 5.0rc8 and amd-staging-drm-next-git-b8cd95e15410.
What is needed to resolve this? My system remains unstable with frequent/continues crashes. Hard reset is the only option.

Is there anything I can do to help get this bug resolved?
My system remains unstable, with hardware resets the only solution.
