| |
Hi Prarit,
I noticed that commit dbcbfe6aa0d61ae5e13cab43b30802482007c199 ("cpufreq: hold policy->rwsem for duration of changing governors") will cause this problem:
root@nhm4 ~# echo performance > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor -bash: echo: write error: Invalid argument
root@nhm4 ~# cat /sys/devices/system/cpu/cpu3/cpufreq/scaling_available_governors conservative userspace powersave ondemand performance
Thanks, Fengguang
