Re-exports§

DYNAMIC_THRESHOLD_INIT_VALUE 🔒: Initial value for the dynamic threshold (in BPF units).
DYNAMIC_THRESHOLD_RATE_HIGH 🔒: Target event rate (per second) above which we consider migrations/sticky dispatches too high.
DYNAMIC_THRESHOLD_RATE_LOW 🔒: Target event rate (per second) below which we consider migrations/sticky dispatches too low.
DYNAMIC_THRESHOLD_SCALE_MAX 🔒: Maximum scale factor when far from target (fast convergence when initial threshold is way off).
DYNAMIC_THRESHOLD_SCALE_MIN 🔒: Minimum scale factor when just outside the target band (slow convergence near optimal).
DYNAMIC_THRESHOLD_SLOPE_HIGH 🔒: Slope for “too high” case: scale grows with (rate/HIGH - 1) so we step much harder when rate is many times over target.
DYNAMIC_THRESHOLD_SLOPE_LOW 🔒: Slope for “too low” case: scale grows with deficit so we step harder when rate is near zero.
PERF_MAP_STRIDE 🔒: Must match lib/pmu.bpf.c SCX_PMU_STRIDE for perf_events map key layout.
SCHEDULER_NAME 🔒

adjust_dynamic_threshold 🔒
dynamic_threshold_scale 🔒
get_primary_cpus 🔒
main 🔒
parse_cpu_list
parse_hex 🔒: Parse hexadecimal value from command line (requires “0x” prefix, e.g., “0x2”)
setup_perf_events 🔒: Setup performance counter events for a specific CPU and counter index. counter_idx 0 = migration event (-e), 1 = sticky event (-y).
