zxfoundation.sched.cpupri.core Module Reference

Functions
auto	zxfoundation::sched::cpupri::find_fitness (u8 pri_threshold, const ::lib::cpumask &affinity) noexcept -> u16
	Find the CPU with the lowest RT priority at or below a threshold, restricted by an affinity mask.
auto	zxfoundation::sched::cpupri::init () noexcept -> void
	Initialize the cpupri index.
consteval auto	zxfoundation::sched::cpupri::nr_priorities () noexcept -> u32
	Count of supported priority buckets.
auto	zxfoundation::sched::cpupri::pri_set (u16 cpu, u8 old_pri, u8 new_pri) noexcept -> void
	Update the index for an RT enqueue/dequeue on a CPU.
auto	zxfoundation::sched::cpupri::pri_top (u16 cpu) noexcept -> u8
	Read the cached top RT priority of a CPU.

Variables
constexpr u8	zxfoundation::sched::cpupri::CPUPRI_INVALID = 0xFFU
	Sentinel priority used for "no RT work" buckets.
constexpr u32	zxfoundation::sched::cpupri::CPUPRI_NR_PRIORITIES = 128U
	Highest RT priority supported by the index.
