Anyone ever got the turbo speed to be triggered? I've done various tests to trigger it on PVE, no luck so far with turbostat and just watching /proc/cpuinfo. Also got a Windows guest running, it seems to cap at 2.69Ghz.
current CPU frequency: 2.70 GHz (asserted by call to hardware)
boost state support:
Supported: yes
Active: yes
Boost States: 3
Total States: 8
Pstate-Pb0: 3600MHz (boost state)
Pstate-Pb1: 3200MHz (boost state)
Pstate-Pb2: 3000MHz (boost state)
Pstate-P0: 2700MHz
Pstate-P1: 2500MHz
Pstate-P2: 2200MHz
Pstate-P3: 1800MHz
Pstate-P4: 1400MHz
So i'm eager to see Pstate-Pb{0,1,2} states
EDIT1: i'm getting terrible performance with Geekbench & CPUMark in my Win10 guest. Using VirtIO drivers for storage, network and memory (balloon). QEMU Standard PC (i440FX + PIIX, 1996) - Geekbench Browser
Anyone tested performance on their Windows KVM guest? The perf of T730 is on the level T620 Plus
EDIT2: i see the same level of performance on the PVE host itself: HP HP t730 Thin Client - Geekbench Browser. So it seems not to be related to Windows being virtualized at least. It's PVE + AMD, not doing the frequency scaling right way. I have some other Intel PVE hosts using pstate and they seem to be doing well.
EDIT3: Just found this interesting entry in proc which isn't to be seen on my other PVE hosts with Intel CPU:
root@pve3:~# cat /sys/devices/system/cpu/cpufreq/policy0/bios_limit
2700000
EDIT3: just installed CentOS 7 on another M.2 SATA i had laying and the result is what it should be with PVE as well:HP HP t730 Thin Client - Geekbench Browser
SO it all points to PVE kernel!
