    Phoronix: Many AMD Radeon Graphics Driver Improvements Sent In For Linux 5.8

    As I noted earlier this month, AMD has been amassing many graphics driver improvements for Linux 5.8. On Friday marked their first pull request to DRM-Next of the Radeon graphics driver improvements for this next kernel cycle...

    Would love to see some improvement to the idle power so that my RX570 doesn't waste 29W while the monitors are off and everything is idle.

    I feel like I have to be doing it wrong, but can't get it to idle below 29W. With Gnome + Wayland running it's 35W.

      It's the same w/ my RX580. It has two settings (normal and mining or some bullshit like that), in the mining mode mode memory speed is set higher, rest lower. In the mining mode it uses 17W (similar to Win value in both modes), else 30W. If i change the GPU and memory speed either to either setting, idle power will stay the same according to the mode. So i don't know what else the firmware does. Performance stays the same by the way. No matter if mining or default jumper setting is used...

        Have you checked the clock speeds? My R9 390 keeps running at high clock speeds for some reason, even for simple desktop usage.

          It'd be nice to see Navi 20 squared away before launch similar to Intel product launches.

            The 29W are most likely caused by running the GDDR5 memory modules at the highest frequency and/or by running the shaders at a high frequency irrespective of GPU utilization.

            radeontop can be used to show the current memory and shader clocks. "radeontop -d -" can be used to print clocks when all displays are turned off.

              Will HDMI audio ever work under Wayland? It works with the old radeon driver, so it's obviously an amdgpu bug.

                I want HDMI 2.1 to be supported.
                I want Freesync over HDMI (VRR) to work too and also 4K at 120 Hz.
                If they release Navi 20 with an older version of HDMi than the 3 years old already 2.1, I will not buy any of their cards.
                I don't pay a lot of money for 4 years old technology.
                I want to see movies and play games in the best quality.
                It's enough that they release the software support very late and don't have a control panel, I will not take this kind of disadvantage on the hardware side too.

                    Same here
                    Mine is an MSI version which has also the Zero-RPM feature to stop the fans if they are needed.
                    But guess what, that feature only works on Windows, on Linux they run all the time, even if they are not needed, consuming more power of course and making more noise.
