Hi Sancome,
since many new cpus (N3700 Braswell for ex.) cannot be used at the maximum performances with acpi_freq,
can you compile intel_pstate module in the next release?
I would like to try if it will raise correctly.
thanks

Just execute the insmod.. command.
Then you can see with "dmesg" command if the module identifies you CPU.
the echo commands are necessary to change the CPU governor for each CPU (core) you have.
Hi Sancome,
thanks for the new version! XPEnoboot_DS3615xs_5.1-5022.3 works fine for AMD CPU:
[ 168.210238] powernow-k8: Found 1 AMD E-350 Processor (2 cpu cores) (version 2.20.00)
[ 168.210311] powernow-k8: 0 : pstate 0 (1600 MHz)
[ 168.210315] powernow-k8: 1 : pstate 1 (1280 MHz)
[ 168.210318] powernow-k8: 2 : pstate 2 (800 MHz)
I just needed to load the module and change the governor to ondemand:
insmod /lib/modules/powernow-k8.ko
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
grep "MHz" /proc/cpuinfo
cpu MHz : 800.000
cpu MHz : 800.000
Can you suggest where should I put them to load on boot? Some /etc/init/rc.* should be fine?
thanks
Hi Sancome,
would you add powernow-k8 module and cpufreq-utils or cpupower utilties in the next build?
It would be fine to limit CPU power when unused also on AMD cpu. In kernel 3.2 acpi-cpufreq module is not able to handle AMD cpu yet.
thanks
