Struct dpdk_unix::SysPath

pub struct SysPath(_);

Represents /sys.

Methods

impl SysPath

pub fn is_a_numa_machine(&self) -> bool

Is this a NUMA-based machine?

pub fn is_a_numa_node(&self, numa_node: u8) -> bool

Is this a NUMA node (assuming we're on a NUMA-based machine)?

Note that this might be a fake NUMA node, ie one lacking any hyper threads.

pub fn hyper_thread_path(     &self,     hyper_thread: HyperThread,     file_name: &str ) -> PathBuf

A hyper thread file.

pub fn numa_node_path(&self, numa_node: u8, file_name: &str) -> PathBuf

A NUMA node file.

pub fn pci_device_path(     &self,     pci_device: (u32, u8, u8, u8),     file_name: &str ) -> PathBuf

A PCI device file.

pub fn hyper_threads_path(&self, file_name: &str) -> PathBuf

A path about all hyper threads.

pub fn numa_nodes_path(&self, file_name: &str) -> PathBuf

A path about all NUMA nodes.

pub fn pci_devices_path(&self, file_name: &str) -> PathBuf

A path about all PCI devices.

pub fn rescan_all_pci_buses_and_devices(&self) -> Result<()>

Rescans all PCI buses and devices.

Errors are swallowed.
