Bug ID: 201991
Summary: amdgpu: clock management is disabled for the 4K
resolution with polaris 10
Product: Drivers
Version: 2.5
Kernel Version: 4.18.0,4.20.0-rc6, drm-next-4.21-wip
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: enhancement
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org

simple app for the amdgpu sys interface
When the Xfce desktop is visible at 4K and idling, the engine clock is fixed at
level 6: 1220MHz and you can not change that. The temperature is 38 C. When the
monitor is sleeping, then the engine clock is 300Mhz. The automatic power
management works with 2560x1600 and lower resolutions as espected. I tested
with my python app and I have latest drivers, including firmware files. My
monitor is ASUS VP28UQG and I use the display port.

You might consider if you are trying out radeon-profile.

That uses the same sysfs api and uses old qt or special modules (like
qtchartview) that are not compatible with latest qt packages. In other words
that app is broken on several distributions. When programming simple GUIs, use
python gtk that does not break so easily.

Adding amdgpu.ppfeaturemask=0xffffffff to the kernel command line makes the
powerplay feature to work normally at 4K.
uname -r
4.20.0-rc3+

the above kernel command line is still necessary in 2022 with mesa 22.
Why has this not been fixed in source to not need the clock/voltage adjustment
parameter for automatic clocks when using 4K monitor output?

The driver set minimum required clocks to meet the required bandwidth and
voltage for the attached displays. When you enable overclocking (via the bit
in ppfeaturemask), that gets partially disabled to allow the user to manually
adjust the clocks at their own risk.
