            Bug ID: 108322
           Summary: RX580 Display flickering after waking from suspend
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: bmilreu@gmail.com

GPU RX580 Nitro+ over DisplayPort to a single AOC 75hz monitor. Issue is on
last kernels 4.18 4.19 but not in 4.14.

Screen starts flickering until reboot if I sleep/wake or if I manually switch
the monitor off/on.

Tried to turn amdgpu.dc=0, screen then flickers everywhere anytime unless I
manually change frequency from 75hz to 60hz. That only solves it inside KDE
though.

Checking gpu related logs shows this error, but couldn't find anything else:
"Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff"

Compiled last AMD-drm-next kernel from git and problem's still here, even
worse, it's now flickering everywhere at 75hz.
Discovered from another bug report that forcing clocks to high "fixed" the
flickering, and it does indeed.
It also doesn't flicker if I force 60hz everywhere. It's worth mentioning its a
1080p Freesync 75hz DP1.2 monitor.

Created custom modes and forced it into xrandr. 75hz flickers, but 73hz is
working fine it seems. This is on last amd-drm-next-staging 

~ >>> gtf 1920 1080 73                                                          

  # 1920x1080 @ 73.00 Hz (GTF) hsync: 82.20 kHz; pclk: 214.37 MHz
  Modeline "1920x1080_73.00"  214.37  1920 2056 2264 2608  1080 1081 1084 1126 
-HSync +Vsync
~ >>> xrandr --newmode "1920x1080_73.00"  214.37  1920 2056 2264 2608  1080
1081 1084 1126  -HSync +Vsync                                                  
     [130]
~ >>> xrandr --addmode DisplayPort-0 "1920x1080_73.00"                          
~ >>> xrandr --output DisplayPort-0 --mode "1920x1080_73.00"                    

Will keep it like this for now and test it in games, but in kde plasma/chromium
73hz is smooth as silk it seems. Another thing I noticed is gtf generates
higher pixel clocks than the ones from my monitor (edid?). You can compare
above result with the attached xorg log.

This would be unrelated - those patches are still in review and not part of any
tree yet.

Luminance flickering is also a bit different from typical flickering. It is a
more subtle effect and doesn't have any sort of visual corruption associated
with it - lines, the screen displaying black, etc.
