Struct HypCam 

pub struct HypCam { /* private fields */ }

A PCI configuration access mechanism using hypercalls implemented by the x86-64 pKVM hypervisor.

Implementations

impl HypCam

pub fn new(phys_base: PhysAddr, cam: Cam) -> Self

Creates a new HypCam for the PCI root complex at the given physical base address.

pub fn is_pkvm() -> bool

Returns whether we are running under pKVM by checking the CPU ID signature.

Trait Implementations

impl ConfigurationAccess for HypCam

fn read_word(&self, device_function: DeviceFunction, register_offset: u8) -> u32

Reads 4 bytes from the configuration space.

fn write_word( &mut self, device_function: DeviceFunction, register_offset: u8, data: u32, )

Writes 4 bytes to the configuration space.

unsafe fn unsafe_clone(&self) -> Self

Makes a clone of the ConfigurationAccess, accessing the same PCI bus.
