Struct rustsbi::HartMask

pub struct HartMask { /* fields omitted */ }

Hart mask structure reference

Implementations

impl HartMask

pub unsafe fn from_addr(
    vaddr: usize,
    base: usize,
    max_hart_id: usize
) -> HartMask

Construct a reference to hart mask from bit vector and starting hartid.

Parameters

• The vaddr is a scalar bit-vector containing hartids. Should return address from supervisor level.
• The base is the starting hartid from which bit-vector must be computed. If base equals usize::MAX, that means vaddr is ignored and all available harts must be considered.
• The max_hart_id should be returned by SBI implementation for maximum hart id this hart mask supports.

Unsafety

Caller must ensure all usize values in the bit vector is accessible.

pub fn has_bit(&self, hart_id: usize) -> bool

Check if the hart_id is included in this hart mask structure.
