Struct Arm64RegisterIo 

pub struct Arm64RegisterIo<T> { /* private fields */ }

An implementation of HypercallIo on top of Arm64RegisterState.

Implementations

impl<T: Arm64RegisterState> Arm64RegisterIo<T>

pub fn new(t: T, pre_advanced: bool, smccc: bool) -> Self

Returns a new instance.

If pre_advanced, the PC has already been advanced (which the ARM processor does automatically when the HVC instruction is executed).

If smccc, this is the SMCCC calling convention (hvc #0). Otherwise, it is the Hyper-V calling convention (hvc #1).

Trait Implementations

impl<T> AsHandler<T> for Arm64RegisterIo<&mut T>

fn as_handler(&mut self) -> &mut T

Gets the inner handler.

impl<T> AsHandler<T> for Arm64RegisterIo<T>

fn as_handler(&mut self) -> &mut T

Gets the inner handler.

impl<T: Arm64RegisterState> HypercallIo for Arm64RegisterIo<T>

fn advance_ip(&mut self)

Advances the instruction pointer for a completed hypercall.

fn retry(&mut self, control: u64)

Retains the instruction pointer at the hypercall point so that the hypercall will be retried.

fn control(&mut self) -> u64

The hypercall input value.

fn input_gpa(&mut self) -> u64

The guest address of the hypercall input.

fn output_gpa(&mut self) -> u64

The guest address of the hypercall output.

fn fast_register_pair_count(&mut self) -> usize

Returns the maximum number of fast register pairs.

fn extended_fast_hypercalls_ok(&mut self) -> bool

Returns whether extended fast hypercall input/output is allowed.

fn fast_input( &mut self, buf: &mut [[u64; 2]], output_register_pairs: usize, ) -> usize

Fills the buffer with fast input parameters. Given an output size in register pairs, returns the index of the first output register pair.

fn fast_output(&mut self, starting_pair_index: usize, buf: &[[u64; 2]])

Writes fast output registers from the buffer.

fn vtl_input(&mut self) -> u64

The VTL switch hypercall input parameter.

fn set_result(&mut self, n: u64)

Sets the hypercall result.

fn fast_regs(&mut self, starting_pair_index: usize, buf: &mut [[u64; 2]])

Reads fast input/output registers into a buffer, given the starting pair index.
