Title:
Turbo Core doesn't work on an AMD Phenom II X6 1045T
Status in The Linux Kernel:
Unknown
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
I'm using Ubuntu 12.10 (64 bit) and my AMD Phenom II X6 1045T doesn't
boost from 2.7 GHz to 3.2 GHz if a core is using 100% of cpu time.
sworddragon@ubuntu:~$ uname -a
Linux ubuntu 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
sworddragon@ubuntu:~$ dmesg | grep powernow
[ 1.204050] powernow-k8: Found 1 AMD Phenom(tm) II X6 1045T Processor (6 cpu cores) (version 2.20.00)
[ 1.204074] powernow-k8: Core Performance Boosting: on.
[ 1.204110] powernow-k8: 0 : pstate 0 (2700 MHz)
[ 1.204113] powernow-k8: 1 : pstate 1 (2000 MHz)
[ 1.204115] powernow-k8: 2 : pstate 2 (1400 MHz)
[ 1.204117] powernow-k8: 3 : pstate 3 (800 MHz)
sworddragon@ubuntu:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
2700000 2000000 1400000 800000
My BIOS is showing correctly 3.2 GHz as the maximum frequenzy and if I disable Cool' n' Quiet my frequenzy will be constantly 2705.104 MHz for all cores in /proc/cpuinfo without boosting to 3.2 GHz if a core is using 100% of cpu time.
