Fields

exit_dump_len: u32

Exit debug dump buffer length. 0 indicates default.

slice_us: u64

Maximum scheduling slice duration in microseconds.

slice_us_lag: u64

Maximum time slice lag in microseconds.

A positive value can help to enhance the responsiveness of interactive tasks, but it can also make performance more “spikey”.

cpu_busy_thresh: u64

CPU busy threshold.

Specifies the CPU utilization percentage (0-100%) at which the scheduler considers the system to be busy.

polling_ms: u64

Polling time (ms) to refresh the CPU utilization.

This interval determines how often the scheduler refreshes the CPU utilization that is compared with the CPU busy threshold (option -c) to decide if the system is busy or not.

Value is clamped to the range [10 .. 1000].

0 = disabled.

primary_domain: Option<String>

Specifies a list of CPUs to prioritize.

Accepts a comma-separated list of CPUs or ranges (i.e., 0-3,12-15) or the following special keywords:

“turbo” = automatically detect and prioritize the CPUs with the highest max frequency, “performance” = automatically detect and prioritize the fastest CPUs, “powersave” = automatically detect and prioritize the slowest CPUs, “all” = all CPUs assigned to the primary domain.

By default “all” CPUs are used.

preferred_idle_scan: bool

Enable preferred idle CPU scanning.

With this option enabled, the scheduler will prioritize assigning tasks to higher-ranked cores before considering lower-ranked ones.

stats: Option<f64>

Enable stats monitoring with the specified interval.

monitor: Option<f64>

Run in stats monitoring mode with the specified interval. Scheduler is not launched.

verbose: bool

Enable verbose output, including libbpf details.

version: bool

Print scheduler version and exit.

help_stats: bool

Show descriptions for statistics.

libbpf: LibbpfOpts
