What has been done here is incorrect. The old "ondemand" script was modified so that if the intel_pstate driver was being used, and therefore "ondemand" did not exist, it would fall through to setting the "powersave" governor (refer to bug #1314643). Note that "powersave" with the intel_pstate CPU frequency scaling driver is NOT the same as "powersave" with the acpi-cpufreq CPU frequency scaling driver.
The preferred governor with the intel_pstate driver is powersave. I'm saying that this: # more modern processors that support intel_pstate behave worse with # ondemand/powersave and should use performance if [ `cat /sys/devices/system/cpu/cpu$FIRSTCPU/cpufreq/scaling_driver` = intel_pstate ]; then echo 'CPU supports intel_pstate, keeping "performance"' exit 0 fi is incorrect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1579278 Title: Keep powersave CPU frequency scaling governor for CPUs that support intel_pstate To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1579278/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
