Struct TrapFrame

#[repr(C, packed(1))]
pub struct TrapFrame {
    pub r11: u64,
    pub r10: u64,
    pub r9: u64,
    pub r8: u64,
    pub rsi: u64,
    pub rdi: u64,
    pub rdx: u64,
    pub rcx: u64,
    pub rax: u64,
    pub err_code: u64,
}

TrapFrame is saved and restored by the interrupt handler assembly code upon interrupt entry and exit.

Fields

r11: u64

r10: u64

r9: u64

r8: u64

rsi: u64

rdi: u64

rdx: u64

rcx: u64

rax: u64

err_code: u64

for some exceptions, the CPU automatically pushes an error code (see docs/interrupt.txt) to the stack. For those who don’t have error code, we manually push a dummy value (0)
