.TH TUNED_PROFILES_CPU_PARTITIONING "7" "22 Nov 2022" "TuneD"
|
||||
.SH NAME
|
||||
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,
|
||||
but gives more flexibility on the C-States configuration.
|
||||
|
||||
.SH CONFIGURATION
|
||||
The cpu-partitioning-powersave profile is configured by editing the
|
||||
.I /etc/tuned/cpu-partitioning-powersave-variables.conf
|
||||
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.
|
||||
|
||||
|
||||
.SH IMPORTANT NOTES
|
||||
|
||||
.IP *
|
||||
Same recommendations as tuned\-profiles\-cpu\-partitioning (7) apply.
