The cpu driver defaults to acpi-cpufreq, since this is a zen 1 cpu
amd-pstate is not supported, so there are 3 available freqs (cpupower frequency-info): P0= 2700MHz, P1= 1900MHz, P2= 1200MHz
plus the boost up to 2.9 GHz. The available idle states are: POLL, C1, C2 (cpupower idle-info)
here are the results:
power OFF – BMC ON
w/ mngmt eth + 1 intel i210 connected: 5.7W
w/o any eth connected: 4.9W
power ON
cpu governor: schedutil – no powertop
- idle: 20.5W
- stress -c2: 30.1W
- stress -c4: 36.7W
cpu governor: powersave – powertop --autotune
- idle: 20.2W
- stress -c2: 24.3W
- stress -c4: 25.4W
