-tuned\-profiles\-cpu\-partitioning\-powersave - Partition CPUs into isolated and housekeeping with C-States enabled
-
-.SH DESCRIPTION
-The cpu\-partitioning\-powersave profile is similar to cpu\-partitioning profile,

-
-.SH CONFIGURATION
-The cpu-partitioning-powersave profile is configured by editing the

-file. There are three configuration options:
-
-.TP
-.B 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.
-.TP
-.B 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.
-.TP
-.B 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.
