Fields

slice_us: u64

Maximum scheduling slice duration in microseconds.

dsq_topology: DsqTopology

Topology level of the user-created DSQs.

ordering: QueueOrdering

Ordering algorithm for the queue key of vtime-ordered DSQs.

idle_policy: IdlePolicy

Wakeup idle-CPU selection policy.

no_wake_sync: bool

Disable synchronous-wakeup bias during idle CPU selection.

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:

“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.

enable_preemption: bool

Enable preempting the running task when an eligible sleeper wakes up on its CPU.

perf_config: PerfEventSpec

Hardware/software perf event to monitor for the event-heavy migration hint (0x0 = disabled). Accepts hex (0xN) or a symbolic name (e.g. cache-misses, LLC-load-misses, page-faults, branch-misses).

perf_threshold: u64

Threshold (events accumulated over a slice) above which a task is classified as event-heavy and biased toward migrating to an idle CPU. The behavior is gated on –perf-config.

perf_sticky: PerfEventSpec

Sticky perf event (0x0 = disabled). When a task exceeds –perf-sticky-threshold for this event, keep it on its previous CPU. Accepts hex (0xN) or a symbolic name.

perf_sticky_threshold: u64

Sticky perf threshold; a task is kept on its previous CPU when its count for the –perf-sticky event exceeds this. The behavior is gated on –perf-sticky.

exit_dump_len: u32

Exit debug dump buffer length. 0 indicates default.

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.

debug: bool

Enable BPF debugging via /sys/kernel/tracing/trace_pipe.

verbose: bool

Enable verbose output, including libbpf details.

version: bool

Print scheduler version and exit.

help_stats: bool

Show descriptions for statistics.

libbpf: LibbpfOpts
