Alex's amd-staging-drm-next tree <a href="https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next">https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next</a> Dave's drm-next-amd-dc-staging <a href="https://cgit.freedesktop.org/~airlied/linux/log/drivers/gpu/drm/amd/amdgpu?h=drm-next-amd-dc-staging">https://cgit.freedesktop.org/~airlied/linux/log/drivers/gpu/drm/amd/amdgpu?h=drm-next-amd-dc-staging</a> We believe this issue has been fixed but had trouble identifying the fix. We only had a Dell 5k display to test with. There's a chance this is monitor specific. Please build with CONFIG_DRM_AMD_DC_PRE_VEGA or pass the amdgpu.dc=1 module option and ensure dc is loaded by checking 'dmesg | grep Display'. You should get the following: [drm] Display Core initialized! If the issue still reproduces we might have to give this another try or see if we can find that HP z27q panel. Thanks for your help on this.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
