TUNED_PROFILES_CPU_PARTITIONING(7)

NAME
tuned-profiles-cpu-partitioning-powersave - Partition CPUs into isolated and housekeeping with C-States enabled

DESCRIPTION
The cpu-partitioning-powersave profile is similar to cpu-partitioning profile, but gives more flexibility on the C-States configuration.

CONFIGURATION
The cpu-partitioning-powersave profile is configured by editing the /etc/tuned/cpu-partitioning-powersave-variables.conf file. There are three configuration options:

isolated_cores=<CPU-LIST>
    List of CPUs to isolate. This option is mandatory. Any CPUs not in this list is automatically considered a housekeeping CPU.

no_balance_cores=<CPU-LIST>
    List of CPUs not be considered by the kernel when doing system wide process load-balancing. Usually, this list should be the same as isolated_cores=. This option is optional.

max_power_state=<MAX_CSTATE>
    Maximum c-state the cores are allowed to enter. Can be expressed as it's name (C1E) or minimum wake-up latency, in micro-seconds. This parameter is provided as-is to `force_latency`. Default is set to "cstate.name:C1|10" to behave as cpu-partitioning profile.

IMPORTANT NOTES

*   Same recommendations as tuned-profiles-cpu-partitioning (7) apply.
