Struct VmState 

pub struct VmState {
    pub regs: [u64; 13],
    pub program_counter: u64,
    pub mapped_heap_pages: RangeSet,
    pub resident_pages: RangeSet,

    pub audio: Option<AudioMode>,
    /* private fields */
}

Inner VM state.

Fields

regs: [u64; 13]

Registers.

program_counter: u64

Program counter.

mapped_heap_pages: RangeSet

Mapped heap memory pages’ indices.

These pages were allocated by the guest but not necessarily read from/written to.

Note that it’s possible to include only a subset of the pages if you’re sure that they will not be touched again during the program run. Howeve,r if such a page is touched the engine will panic.

resident_pages: RangeSet

All memory pages that were read from/written to by the guest but haven’t been unmapped yet.

Note that it’s possible to include only a subset of the pages if you’re sure that they will not be touched again during the program run. However, if such a page is touched the engine will silently initialize it from the default: from zeroes for stack/heap and from the program’s RW data section for RW data. The program might continue without an error after that, but the output will most likely be incorrect.

kernel: KernelState

The state of the Linux kernel syscall layer.

video: Option<VideoMode>

Video output mode.

audio: Option<AudioMode>

Audio output mode.
