https://bugs.freedesktop.org/show_bug.cgi?id=108379
Bug ID: 108379
Summary: high idle power consumption
Product: DRI
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: grmat@sub.red
system:
- Polaris10 (Ellesmere)
- Linux 4.18.14
- WQHD (2560*1440 pixels) monitor with 144 Hz (DisplayPort)
expected behaviour:
GPU power states should be lowered to the minimum states while idling to save
power, heat and noise.
actual behaviour:
- DC on (default):
GPU stuck at highest SCLK DPM state, power consumption as per amdgpu_pm_info
is ~24 Watts
- amdgpu.dc=0:
MCLK stuck at high DPM state, power consumption as per amdgpu_pm_info is ~26
Watts
- Windows:
correct (lowest) SCLK/MCLK DPM states, measured power consumption is ~16
Watts lower compared to Linux
Note: https://bugzilla.kernel.org/show_bug.cgi?id=201275 fixed a regression
causing *additional* power draw (SCLK and MCLK both at max, power consumption
at ~38 Watts while idling).
I can't tell if it's a regression as I've just recently got the GPU. Randomly
tested kernels from within 4.17 to 4.18.14 all suffer from this issue.

Please attach your xorg log (if using X) and dmesg output.

The SCLK is still fixed at max clock with WQHD, 144 Hz. Is Polaris considered
legacy already?

I have RX470 and high idle power consumption has been present since hdmi/dp
audio has been in kernel. Power consumption meter readings are ~20w higher with
audio enabled. I am using Gentoo and compiling kernel without hdmi/dp audio
support normalizes consumption.
