--- Comment #36 from Shmerl <shtetldik@gmail.com> ---
OK, I recorded some data after different steps.
Sapphire Pulse RX 5700 XT, LG 27GL85-B (2560x1440, 144 Hz), DisplayPort 1.4
connection enabled in the monitor, DP 1.4 cable used.
1. After normal, boot:
auto
GFX Clocks and Power:
875 MHz (MCLK)
800 MHz (SCLK)
300 MHz (PSTATE_SCLK)
100 MHz (PSTATE_MCLK)
750 mV (VDDGFX)
30.0 W (average GPU)
no flickering.
2. Doing:
echo "high" > /sys/class/drm/card0/device/power_dpm_force_performance_level
GFX Clocks and Power:
875 MHz (MCLK)
2045 MHz (SCLK)
300 MHz (PSTATE_SCLK)
100 MHz (PSTATE_MCLK)
1200 mV (VDDGFX)
33.0 W (average GPU)
no flickering
3. Doing:
echo "low" > /sys/class/drm/card0/device/power_dpm_force_performance_level
GFX Clocks and Power:
875 MHz (MCLK)
300 MHz (SCLK)
300 MHz (PSTATE_SCLK)
100 MHz (PSTATE_MCLK)
750 mV (VDDGFX)
30.0 W (average GPU)
no flickering
4. Then, before suspending:
echo "auto" > /sys/class/drm/card0/device/power_dpm_force_performance_level
5. Suspend, and resume:
auto
GFX Clocks and Power:
100 MHz (MCLK)
800 MHz (SCLK)
300 MHz (PSTATE_SCLK)
100 MHz (PSTATE_MCLK)
750 mV (VDDGFX)
10.0 W (average GPU)
strong flickering
6. After that doing:
echo 'high' > power_dpm_force_performance_level
GFX Clocks and Power:
875 MHz (MCLK)
2045 MHz (SCLK)
300 MHz (PSTATE_SCLK)
100 MHz (PSTATE_MCLK)
1200 mV (VDDGFX)
33.0 W (average GPU)
no flickering
7. Doing:
echo 'low' > power_dpm_force_performance_level
GFX Clocks and Power:
100 MHz (MCLK)
300 MHz (SCLK)
300 MHz (PSTATE_SCLK)
100 MHz (PSTATE_MCLK)
750 mV (VDDGFX)
10.0 W (average GPU)
no flickering!
8. And then:
echo 'auto' > power_dpm_force_performance_level
GFX Clocks and Power:
100 MHz (MCLK)
800 MHz (SCLK)
300 MHz (PSTATE_SCLK)
100 MHz (PSTATE_MCLK)
750 mV (VDDGFX)
10.0 W (average GPU)
flickering again!
