https://bugs.freedesktop.org/show_bug.cgi?id=110865 --- Comment #22 from Dieter Nützel --- Hello Alex and Martin, I've tried both on my Polaris 20, RX580 8 GB Sapphire Technology Limited Nitro+ Radeon RX 580 - v2 patched into amd-staging-drm-next (before inclusion of v3) - v3 with amd-staging-drm-next https://cgit.freedesktop.org/~agd5f/linux/commit/?h=amd-staging-drm-next=ca82748783d8189a54a85f2ea1c2710182ba6138 Both flicker with green/black (?) horizontally lines over both screens. Mostly during power level switch. For example during mouse movement/interaction (wheel) and mouse pointer traverse from konsole/etc. to desktop (KDE5 Plasma 5.xx, here). UVD load (mplayer etc.) is not enough to fix it. E.g. radv (vkcube) not. But other gfx load (vkmark/glmark2, etc.). When there is lower gfx demand during the above tests (glmark2 -b buffer) the flicker came up, again. Martin's observation [-] If i do "echo low > /sys/class/drm/card0/device/power_dpm_force_performance_level" the flickering stops. So the flickering is caused by the automatic powermanagement / reclocking. [-] Works here, too (tested with v3). But I never could go below ~32 W !!! Tested with both Nitro+ BIOS modes. The PSTATE_ wouldn't change on my card. They stay @ 600/1000 all the time!? GFX Clocks and Power: 300 MHz (MCLK) 300 MHz (SCLK) 600 MHz (PSTATE_SCLK) 1000 MHz (PSTATE_MCLK) 750 mV (VDDGFX) 32.76 W (average GPU) GPU Temperature: 31 C GPU Load: 0 % MEM Load: 3 % Any hints?

Since they likely don't align, especially if the monitors have different timing, we have to use a fixed mclk. The DC modesetting code can lock the timing of multiple monitors if they are using the exact same timing so that the blanking periods align, but I don't think the Linux power management code takes this into account at the moment. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

[Bug 110865] Rx480 consumes 20w more power in idle than under Windows
https://bugs.freedesktop.org/show_bug.cgi?id=110865 Bug ID: 110865 Summary: Rx480 consumes 20w more power in idle than under Windows Product: Mesa Version: 19.1 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: mw...@adiumentum.com QA Contact: dri-devel@lists.freedesktop.org Created attachment 144485 --> https://bugs.freedesktop.org/attachment.cgi?id=144485=edit logfiles as requested in the amd bugreport guide First I am not sure where to file that bug, so please be gentle with me, if I selected the wrong component. I noticed for a while higher temperatures of my Videocard when my pc was just idling with gnome. Then I dug deeper and found out that my "zero fan" videocard does not stop the fan when I run Linux. So I ran this line here: watch -n 0.5 cat /sys/kernel/debug/dri/0/amdgpu_pm_info and it showed me that the MCLK does not clock down to 300MHz as it does with Windows 10. GFX Clocks and Power: 2000 MHz (MCLK) 300 MHz (SCLK) 300 MHz (PSTATE_SCLK) 300 MHz (PSTATE_MCLK) 1000 mV (VDDGFX) 24.75 W (average GPU) GPU Temperature: 45 C GPU Load: 0 % I have a multimonitor setup with two 1920x1200 pixel screens. When I use Windows 10, the MCLK does not go beyond 300MHz when the desktop is idling. (measured with hwmonitor) When I power-off one screen under linux the (average GPU) goes down to 8-10W and the MCLK drops to 300MHz, so the card can clock down, but is somehow prohibited by the driver or configuration? I followed this bug report guide from amd: https://www.amd.com/en/support/kb/faq/amdgpu-installation#faq-Reporting-Bugs and attached several logfiles. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
