Struct NativeCpu 

pub struct NativeCpu { /* private fields */ }

Native CPU state arena and guest memory owner.

v86’s scalar CPU state uses the first 4 KiB of the arena. The guest RAM is allocated by the core memory module and addressed with 32-bit guest physical addresses, matching the original emulator model.

Implementations

impl NativeCpu

pub fn new(ram_bytes: u32, vga_bytes: u32) -> Self

pub fn ram_bytes(&self) -> u32

pub fn vga_bytes(&self) -> u32

pub fn step(&mut self, max_instructions: u32) -> u32

pub fn read_memory(&self, address: u32, output: &mut [u8]) -> bool

pub fn write_memory(&mut self, address: u32, input: &[u8]) -> bool

pub fn instruction_pointer(&self) -> u32

pub fn halted(&self) -> bool

pub fn state_arena(&self) -> &[u8; 4096]

pub fn vga_text_snapshot(&self) -> Option<(u32, u32, Vec<u8>)>

Return the restored SVGA framebuffer as packed RGB bytes. The native runtime keeps the framebuffer in the same guest-visible backing store used by v86’s LFB mapping.

pub fn vga_framebuffer_rgb(&self) -> Option<(u32, u32, Vec<u8>)>

pub fn set_9p_root(&mut self, path: impl AsRef<Path>) -> Result<(), String>

impl NativeCpu

pub fn restore_v86_state( &mut self, state: &Value, buffers: &[Vec<u8>], ) -> Result<(), String>

Restore the CPU scalar state and packed RAM representation from the decoded v86 state object. Device arrays are intentionally left to the outer native device graph, but CPU execution can continue after this method completes.
