Manual setting of pp_dpm_sclk resets after monitor off/on.=20

1.setting:
echo manual > /sys/class/drm/card0/device/power_dpm_force_performance_le=
vel
echo 2 > /sys/class/drm/card0/device/pp_dpm_sclk
echo 95 > /sys/class/drm/card0/device/hwmon/hwmon1/pwm1

2. checking:
cat /sys/class/drm/card0/device/pp_dpm_sclk=20
0: 300Mhz=20
1: 608Mhz=20
2: 910Mhz *
3: 1077Mhz=20
4: 1145Mhz=20
5: 1191Mhz=20
6: 1236Mhz=20
7: 1303Mhz=20

cat /sys/class/drm/card0/device/power_dpm_force_performance_level
manual

cat /sys/class/drm/card0/device/hwmon/hwmon1/pwm1
91

3. switching monitor off/on

4. checking again:
cat /sys/class/drm/card0/device/pp_dpm_sclk=20
0: 300Mhz=20
1: 608Mhz=20
2: 910Mhz=20
3: 1077Mhz=20
4: 1145Mhz=20
5: 1191Mhz=20
6: 1236Mhz=20
7: 1303Mhz *

cat /sys/class/drm/card0/device/power_dpm_force_performance_level
manual

cat /sys/class/drm/card0/device/hwmon/hwmon1/pwm1
91




The card is under opencl load (blender) but the problem exists regardless of
the load.
So, the dpm_performance_level still says manual but the clock is changed to
auto again.

GPU: rx480 (MSI) connected via DisplayPort (I didn't try HDMI)=20
OS: Slackware current
Affected kernels (that I've tried): 4.17.1, 4.17.2, 4.17.3, 4.18rc3,
4.18.0-rc1-custom-g6becad35ec8a-dirty

Kernels that work properly (the ones I've tried): 4.16.14, 4.16.15, 4.16.17.


It's my first bug report so I apologize in advance for any mistakes.
