Struct HypercallAbi

pub struct HypercallAbi {
    pub(crate) hypercall_id: usize,
    pub(crate) args: Vec<usize>,
    pub(crate) res: Vec<usize>,
}

Architecture-agnostic wrapper for any hypercall ABI between CrosVM and the guest.

Fields

hypercall_id: usize

args: Vec<usize>

res: Vec<usize>

Implementations

impl HypercallAbi

pub fn new(hypercall_id: usize, args: &[usize], default_res: &[usize]) -> Self

Creates a new HypercallAbi instance, with the default error result.

pub fn hypercall_id(&self) -> usize

Returns the hypercall unique identifier, for routing.

pub fn get_argument(&self, n: usize) -> Option<&usize>

Returns the n-th guest-provided architecture-specific arguments.

pub fn get_results(&self) -> &[usize]

Returns the architecture-specific results for the guest, if set.

pub fn set_results(&mut self, res: &[usize])

Sets the architecture-specific results for the guest.
