Hello, At first congrats for submitting the pull request. I hope the dc code is accepted and included in the 4.15 kernel. Me and some other users of my kernel builds (https://github.com/M-Bab/l inux-kernel-amdgpu-binaries) found further regressions in builds based on amd-staging-4.12 and amd-staging-drm-next. I can confirm these regressions affecting my PC with R9 380 GPU, running on Xubuntu 17.04 with mesa 17.2 stable: amd-staging-4.12: When the GPU needs to wake up there is a significant chance that the display freezes (black screen, login screen or crazy pattern). Can't tell if the whole system is frozen as well. This can happen either after wake-up from standby or after resuming from lockscreen (where the GPU seams to be shut off as well). amd-staging-drm-next: Considering it is the latest codebase the performance is a bit underwhelming: It starts with trace messages in dmesg during boot (attached). Later on running anything graphical results in full-screen flicker and flickering black lines. Are these issues known already? I can try to git bisect any of them if you are interested. How should dc-kernel users proceed? Is the amd-staging-drm-next the recommended branch until the dc-code is merged?
