Struct Tiers 

Source 
pub struct Tiers {
    pub cpus: Vec<Cpu>,
    pub nr_capacity_tiers: u64,
    pub nr_place_tiers: u64,

}

Fields§

§cpus: Vec<Cpu>§nr_capacity_tiers: u64§nr_place_tiers: u64§asym_capacity: bool

Placement and balance follow capacity.

§sched_asym_capacity: bool

The kernel has an SD_ASYM_CPUCAPACITY domain.

§forced: bool

The hardware estimate was asked for, which makes placement follow capacity whether or not the kernel has such a domain.

§asym_packing: bool§mode: CapacityMode

Where the capacities came from: the kernel’s falls back to the hardware estimate when the kernel exports none.

§tolerance: u32

Largest capacity difference, in percent, within one tier.

Implementations§

Source§

impl Tiers

Source

pub fn new(mode: CapacityMode, tolerance_pct: Option<u32>) -> Result<Self>

Capacities and capacity tiers, from the topology before load.

Source

pub fn read_priorities( &mut self, object: &mut Object, disable: bool, ) -> Result<()>

Ask the kernel for each CPU’s packing priority, after load, and set the packing tiers: from the priorities if every CPU packs and they differ, otherwise from the capacity tiers if placement follows capacity, otherwise one tier.

Source

pub fn publish(&self, object: &Object) -> Result<()>

Hand the tiers to the BPF program, before it attaches.
