Struct dpdk_unix::InterruptRequest

pub struct InterruptRequest(_);

Represents a logical hyper thread, which in Operating System terms is usually a logical CPU (core).

These usually map 1:1 with LogicalCores

Methods

impl InterruptRequest

pub fn read_interrupt_request_to_hyper_threads_affinity(     &self,     proc_path: &ProcPath ) -> Result<BTreeSet<HyperThread>, ListParseError>

Reads interrupt request (IRQ) affinity to hyper threads.

pub fn read_interrupt_request_to_hyper_threads_affinity_hint(     &self,     proc_path: &ProcPath ) -> Result<BTreeSet<HyperThread>, ListParseError>

This logic seems to exist in the Linux kernel to provide a place for the irqbalance daemon to store some configuration.

pub fn read_interrupt_request_node(     &self,     proc_path: &ProcPath ) -> Result<u8, Error>

?numa node? As always, the Linux documentation sucks.

pub fn read_default_interrupt_request_affinity_hyper_thread_mask(     proc_path: &ProcPath ) -> Result<u32, Error>

Default interrupt request affinity hyper thread mask.

pub fn force_all_interrupt_requests_to_just_these_hyper_threads(     hyper_threads: &BTreeSet<HyperThread>,     proc_path: &ProcPath ) -> Result<()>

We ignore failures as the /proc for interrupt requests is brittle.

pub fn interrupt_requests(proc_path: &ProcPath) -> Result<BTreeSet<Self>, Error>

Returns known interrupt requests (IRQs).
