no freeze - dmesg with governor=powersave (3.19.0-rc2-ickle1+)
Hello Ben,
Here the result of my test with governor=powersave.
first I set the governor to powersave and checked it after reboot:
for g in /sys/devices/system/cpu/cpu[0-9]/cpufreq/scaling_governor; do echo
$g=$(cat $g); done
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor=powersave
/sys/devices/system/cpu/cpu1/cpufreq/scaling_governor=powersave
/sys/devices/system/cpu/cpu2/cpufreq/scaling_governor=powersave
/sys/devices/system/cpu/cpu3/cpufreq/scaling_governor=powersave
Booted Kernel regular (without i915.enable_rc6=0 and without
intel_pstate=disable)
Kernel build from ickle git: 3.19.0-rc2-ickle1+ #1 SMP Tue Jan 6 00:57:18 CET
2015 x86_64 x86_64 x86_64 GNU/Linux
I had run some files over a time of almost 2 hour now without a freeze. In the
attached logfile there is just one Kernel trace (perhaps interesting for
Ickle), but it seems to have no impact during the test. The CPU was during the
run mostly like:
cat /proc/cpuinfo | grep "cpu MHz"
cpu MHz : 499.741
cpu MHz : 499.741
cpu MHz : 499.741
cpu MHz : 499.741
Well I will do another test now with the "regular" Kernel 3.17.7 and
governor=powersave just to see if it freeze or also run more "stable".</pre>
