qemu_print

A Rust library to print strings to a console using QEMU's serial port support.

Usage

Add -serial stdio to the QEMU's command line parameters.

qemu-system-x86_64 -serial stdio /* other parameters... */

Invoke macros like as print! and println!.

use qemu_print::qemu_println;

qemu_println!("This string will be printed to the console.");

let x = 3;
qemu_println!("x = {}", x);

Features

This crate has two features:

  • nightly: This is enabled by default. The Nightly Rust must be enabled.
  • stable: Use this feature if you do not use the Nightly Rust. Add default-features = false, features = ["stable"] to Cargo.toml's dependency option. This feature uses cc crate as a build-time dependency. You need to install the compile-time requirements. This feature only supports targets which use System V AMD64 ABI.

Enable one of these features. If both, or none of them are specified, this crate will emit a compile error.
