            Bug ID: 108323
           Summary: RX580 starts doing a constant noise after setting fans
                    to a fixed value, then back to auto
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: bmilreu@gmail.com

I'm using the sysfs API with those steps:


To switch to manual fan control from automatic, run
# echo "1" > /sys/class/drm/card0/device/hwmon/hwmon0/pwm1_enable

Set up fan speed to e.g. 50% (100% are 255 PWM cycles, thus calculate desired
fan speed percentage by multiplying its value by 2.55):

# echo "128" > /sys/class/drm/card0/device/hwmon/hwmon0/pwm1
To reset to automatic fan control, run

# echo "2" > /sys/class/drm/card0/device/hwmon/hwmon0/pwm1_enable


My RX580 Nitro+ starts beeping a constant high pitched weird noise until I set
it back to a fixed value or until reboot. It doesn't happen if start on auto,
only after switching to a value then back to auto.

This is most likely the same issue I encountered some time ago with my RX 580,
which is also a Sapphire Nitro+ (Special Edition but that should not matter). I
opened a bug report on the kernel bugzilla back then[1].

Yes, seems like the same issue. It would be useful to know if someone with a
non-Sapphire RX580 has the same problem.

Bug also triggers using the new sysfs API's fan1_target+fan1_enable on latest
drm-next-4.21-wip

MSI RX 480 Gaming X is also affected.
