Bug ID: 199979
Summary: amdgpu: changing pwm1_enable from 1 to 2 does not
resume automatic fan control
Product: Drivers
Version: 2.5
Kernel Version: 4.17.0
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: CWidmer@umbrox.de
Regression: No
When using the hardware monitoring interface to change pwm1_enable to 2
(automatic) from 1 (manual), the automatic fan control does not work as
expected. Instead, the pwm1 value keeps jumping around between at least two
values and a continuous, persisting, and unpleasantly high-pitched sound can be
heard from inside the computer case. The only way to stop those things is
writing some valid value to pwm1, which in turn also switches pwm1_enable back
to 1. If the system is booted without ever manually changing the pwm1_enable
value, which then defaults to 2, automatic fan control does work as intended.
I am using a custom RX 580 (Sapphire Nitro+ Radeon RX 580 8GD5 Special Edition)
on a Gentoo x86_64 system and was able to reproduce the issue with the 4.17.0
kernel with Gentoo patches, the Ubuntu kernel on the 18.04 image (should be a
4.15 one) and also with amd-staging-drm-next.

This issue is also present on my system with the same card (Sapphire Radeon
RX580 Nitro+ Special Edition) on a recent vanilla kernel (5.8.6).
"pwm1_enable" is 2 after a clean boot. Writing "2" to it again makes the fan
speed switch between 2 speeds rapidly causing a high pitched annoying noise.

Please report here if that's still an issue in 6.4.3.
