Module ostd::arch::x86::qemu

source ·
Expand description

Provides the ability to exit QEMU and return a value as debug result.

Enums§

  • QemuExitCode
    The exit code of x86 QEMU isa debug device. In qemu-system-x86_64 the exit code will be (code << 1) | 1. So you could never let QEMU invoke exit(0). We also need to check if the exit code is returned by the kernel, so we couldn’t use 0 as exit_success because this may conflict with QEMU return value 1, which indicates that QEMU itself fails.

Functions§

  • exit_qemu
    Exits QEMU with the given exit code.
