Struct context_switch::Context

#[repr(C, packed(1))]
pub struct Context { /* private fields */ }

The registers saved before a context switch and restored after a context switch for SSE-enabled Tasks.

Note: the order of the registers here MUST MATCH the order of registers popped in the [restore_registers_sse!] macro.

Implementations

impl ContextSSE

pub fn new(rip: usize) -> ContextSSE

Creates a new ContextSSE struct that will cause the SSE-enabled Task containing it to begin its execution at the given rip.

pub fn set_first_register(&mut self, value: usize)

Sets the value of the first regular (non-SSE) register to the given value.

This is useful for storing a value (e.g., task ID) in that register and then recovering it later with read_first_register().

On x86_64, this sets the r15 register.
