            Bug ID: 211033
           Summary: [bisected][regression] amdgpu: *ERROR* Restoring old
                    state failed with -12
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.10.4
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: zaltys@inbox.ru
        Regression: No

I have AMD RX560 GPU which is connected to LG 27UD-88 display via ATEN CS782DP
displayPort KVM switch.

I can't reliably switch KVM port to the machine running Kernel 5.10.4 with
previously mentioned GPU. Screen is usually blank and display even goes to
standby after the first try, however sometimes (if I switch KVM ports quickly a
few times) it turns on, but with wrong resolution. dmesg complains with:

[drm:dm_restore_drm_connector_state] *ERROR* Restoring old state failed with
-12

for every failed port switch.

KVM switch is configured to "redetect display" - basically it emulates
replugging when port is switched. I have been using it for 4 years with the
same GPU and it worked correctly until Kernel 5.10.4

I did a bisect, and it showed the first bad commit was:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/gpu/drm/amd?h=linux-rolling-stable&id=ea64b21c6638d1ac3120fff89eb20c0e525a21d9

Reverting this commit fixed my issue (it works like pre 5.10.4)

Got same problem on:

Tested with 5.11.0-rc2 and 5600 XT, same issue.

"xset dpms force off" turns the display off and it won't come back,
with the same error in the syslog.

Jan  5 11:11:54 holly kernel: [drm:dm_restore_drm_connector_state
[amdgpu]] *ERROR* Restoring old state failed with -12

Can be worked around by

1) turning display power off completely
2) switching to console
3) turning display power on - linux console shows up
4) switching back to X

Got the same problem with 5.4.86 and AMD RX560.

Reverting the following commit fixed the issue:

Same problem on Arch (5.10.4), AMD RX580. In my case it works without issues if
I set the monitor to 120hz instead of 144hz in GNOME settings.

Can also be worked around by setting the monitor (monitor settings) to Display
Port version 1.1 and thus a lower refresh rate or by using HDMI instead of DP.

--- Comment #6 from Shlomo (shlomo@fastmail.com) ---
I think I have the same bug on Arch after upgrading linux from 5.10.3.arch1-1
to 5.10.4.arch2-1.

My graphics card is Gigabyte Radeon RX VEGA 56 GAMING OC 8G, connected to 6
monitors: 3 HDMI outputs + 3 DisplayPort outputs. (One of the DisplayPort
outputs is connected to a DisplayPort->HDMI converter). No KVM.
All monitors run at 59.95 or 60 Hz.

Sometimes when I try to wake up the monitors, the 3 monitors on the HDMI
outputs (or occasionally just 1 or 2 of them) don't turn back on. dmesg shows:

[   56.906065] [drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* Restoring
old state failed with -12
[   56.936004] [drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* Restoring
old state failed with -12
[   56.976021] [drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* Restoring
old state failed with -12
[   62.646390] [drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* Restoring
old state failed with -12
[   62.671813] [drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* Restoring
old state failed with -12
[   62.697193] [drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* Restoring
old state failed with -12

The DisplayPort outputs work fine.

Sometimes all monitors correctly turn on, but dmesg shows the following errors
which didn't appear before:

[  542.425462] [drm:dce110_enable_timing_synchronization [amdgpu]] *ERROR* GSL:
Timeout on reset trigger!
[  542.592191] [drm:dce110_enable_timing_synchronization [amdgpu]] *ERROR* GSL:

ea64b21c6638d1ac3120fff89eb20c0e525a21d9 "drm/amd/display: Fix memory leaks in
S3 resume" is the first bad commit.

A revert for ea64b21c6638d1ac3120fff89eb20c0e525a21d9 has been queued in
stable-queue, meaning it should show up in 5.10.6 and 5.4.88 if all goes well.

I can confirm this regression with 
AMD Radeon RX 5700 XT (NAVI10, DRM 3.40.0, 5.10.3, LLVM 11.0.0)
I have display only on one monitor of 2 connected with 5.10.4 and 5.10.5

--- Comment #11 from Andreas (icedragon.aw@web.de) ---
I'm sorry, but I can confirm the bug still also for 5.10.6! - it seems to be
more seldom, but existing.
(System: Kubuntu 20.10, Ryzon 7 PRO 4750G - using only integrated GPU)

Wrong channel above, but the trigger was the same - simply 1) switch monitor
off, 2) wakeup the system from standby/suspend and then 3) switch the monitor
on -> (blank screen - no signal).

I can confirm the same issue on 5.10.4 with a 2x 4K KVM setup on an AMD Radeon
Pro WX 5100 (Talos II POWER9 host).

--- Comment #17 from Jan Klos (honza.klos@gmail.com) ---
I don't think this is limited just to KVMs and such. On my Vega 64 +
5.11.3-arch1 (had the same problem with 5.11.2, 5.10 etc.), sometimes, when I
return to PC after a while and my 2 monitors are sleeping, only one monitor
wakes up, the other one remains in sleep mode. Dmesg shows this:

[bře 6 14:22] [drm] perform_link_training_with_retries: Link training attempt 1
of 4 failed
[bře 6 14:23] [drm] perform_link_training_with_retries: Link training attempt 2
of 4 failed
[  +0,473352] [drm] perform_link_training_with_retries: Link training attempt 3
of 4 failed
[  +0,437753] [drm] enabling link 0 failed: 15
[  +0,432276] [drm] perform_link_training_with_retries: Link training attempt 1
of 4 failed
[  +0,405827] [drm] perform_link_training_with_retries: Link training attempt 2
of 4 failed
[  +0,476172] [drm] perform_link_training_with_retries: Link training attempt 3
of 4 failed
[  +0,415466] [drm] enabling link 1 failed: 15

Switching to terminal and waiting a sec or two makes both monitors work,
switching back to X11 and everything is OK. It seems to me that there might be
some kind of bug where if the first link training attempt fails, the subsequent
ones ALWAYS fail as well, so there is actually only a single actual link
training attempt that has a chance to succeed.
