DetailsDescription:
The latest linux kernel on my system makes my AMD Radeon RX 5500XT 8GB (gigabyte) draw 5 times more power on my 75Hz 1080p monitor (LG 24MK430) via HDMI while idling. On 60Hz, it draws about 3 Watt, while on 75Hz draws about 15 Watt. I also installed the latest linux-lts 5.4.87-1 package to test and it works really well, drawing about 3 Watt on 75Hz, but because of how this kernel version works, my system takes way more time to boot if compared to 5.10.5 kernel. Also I installed Gnome and KDE Plasma desktop environments and, while idling, I got the same results (I'm using xfce4 for reference, with xfwm4). Additional info: * package version(s) Linux version 5.10.5.arch1-1 (linux-zen 5.10.5.arch1-1 also does the same) * config and/or log files etc. * link to upstream bug report, if any Steps to reproduce: Install arch linux with the latest kernel on a system with high refresh rate monitor and AMD NAVI GPU. The graphics card will heat doing nothing. |
This task depends upon

I tried all 5.10.X kernels and every single one makes my gpu heat doing nothing with an refresh rate above 60Hz.
