    Phoronix: Linux 4.15 Is Set To Sail Today With AMDGPU DC, Zen Temperature Monitoring, RISC-V

    After going through nine weekly release candidates, the Linux 4.15 kernel is set to be released today as the first major stable update of 2018...

    I wish there was a way to just enable the HDMI audio support but not anything else in AMDGPU DC. I still get terrible graphical performance even with 4.15-rc9 and amdgpu.dc=1 on my RX460. Did they even test it on polaris?

      Did you experience poor preformance prior to 4.15-rc9 or did it get worse?

        Same from 4.15-rc1 to 4.15-rc9, all practically equally bad performance. I'm hoping 4.16-rc1 will show improvement.

          My RX 480 has no discernible degradation with it enabled. RC8 on Debian. Using Mesa 17.2.5 to keep AMDGPU PRO OpenCL for Blender working. Steady 75fps with Unigine Heaven 1920x1080 with Quality Ultra, Tessellation Normal, .

            I've been using DC for ages and switched to rc9 yesterday. I haven't noticed any performance issues on my RX 480.

              Does for any of you RX 4xx owners resume from S3 work with amdgpu?
              I still have to use a kernel from October 2017, because all of the newer ones crash when trying trying to resume from S3 with amdgpu loaded.

                What distribution are you using?

                    Mainline kernels do have partially implemented amdgpu driver. Use AMD 4.17-wip kernel and Oibaf ppa Mesa. How to, see: https://www.youtube.com/watch?v=G3AxgH2bbsE
