Data Structures
struct	zxfoundation::sched::rt::bw::rt_bandwidth
	Per-CPU RT bandwidth accounting block. More...

Functions
auto	zxfoundation::sched::rt::bw::bw_charge (rt_bandwidth &bw, u64 consumed_ns) noexcept -> bool
	Assess the RT bandwidth for the current CPU.
auto	zxfoundation::sched::rt::bw::bw_init (rt_bandwidth &bw, u16 cpu) noexcept -> void
	Initialize one per-CPU RT bandwidth control block.
auto	zxfoundation::sched::rt::bw::bw_replenish (rt_bandwidth &bw) noexcept -> void
	Period replenishment: reset the per-CPU RT runtime counter.
