zxfoundation.sched.nohz.core Module Reference

Data Structures
struct	zxfoundation::sched::nohz::nohz_ops
	Generic per-CPU hook pointers. More...

Enumerations
enum class	nohz_flag : u32 { tick_stopped = 1U << 0 , idle_prepared = 1U << 1 , nr_balance_pending = 1U << 2 }
	Flags written into run_queue::nohz_flags.

Typedefs
using	zxfoundation::sched::nohz::nohz_fn = auto (*)() noexcept -> void
	Default nohz management callbacks — installed during the scheduler init.

Functions
auto	zxfoundation::sched::nohz::balance_pending (u32 flags) noexcept -> bool
	Test whether the nohz-idle kick is pending on the current CPU.
auto	zxfoundation::sched::nohz::clear_balance (u32 &flags) noexcept -> void
	Clear the nohz-balance pending nohz_flag (committed by the balancer on the first pass of the softirq).
auto	zxfoundation::sched::nohz::do_enter_balance () noexcept -> void
auto	zxfoundation::sched::nohz::do_prepare_idle () noexcept -> void
auto	zxfoundation::sched::nohz::do_tick_start () noexcept -> void
auto	zxfoundation::sched::nohz::do_tick_stop () noexcept -> void
auto	zxfoundation::sched::nohz::idle_enter (u32 &flags, const nohz_ops &ops) noexcept -> void
	Enter nohz idle on the current CPU.
auto	zxfoundation::sched::nohz::idle_exit (u32 &flags, const nohz_ops &ops) noexcept -> void
	Exit nohz idle on the current CPU (called on any wakeup).

Variables
void *	context {nullptr}
	This CPU's remote context.
nohz_fn	enter_balance {nullptr}
	Called on wakeup before tick start.
nohz_fn	prepare_idle {nullptr}
	Call before tick stop.
nohz_fn	tick_start {nullptr}
	Actually re-add the periodic timer.
nohz_fn	tick_stop {nullptr}
	Actually issue the timer_cancel.
