| Summary | RX580 Display flickering after waking from suspend |

| Hardware | x86-64 (AMD64) |

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 swit=
ch
the monitor off/on.
Tried to turn amdgpu.dc=3D0, 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&= quot; the flickering, and it does indeed. It also doesn't flicker if I force 60hz everywhere. It's worth mentioning i= ts 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=20

Will keep it like this for now and test it in games, but in kde plasma/chro=
mium
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.
(In reply to bmilreu from comment #10) > https://www.phoronix.com/scan.p= hp?page=3Dnews_item&px=3DAMD-V4-Adaptive-VRR- > FreeSync > Is this maybe related? 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.
Problem still present for me on kernels 4.18, 4.19, 4.20 and 4= .21-drm-next
4.20 released with this bug still, now starts flickering every= where since start like before. Please look at this
