qemu-fw-cfg-rs
A Rust library for reading fw_cfg from QEMU.
Usage
Add the following to your Cargo.toml
:
[dependencies]
qemu-fw-cfg = "0.1"
To use qemu-fw-cfg
without alloc
, you can use this instead:
[dependencies]
qemu-fw-cfg = { version = "0.1", default-features = false }
Examples
use qemu_fw_cfg::FwCfg;
// Verify that we are inside QEMU.
if running_in_qemu() {
// Create a new `FwCfg` instance.
let fw_cfg = unsafe { FwCfg::new().unwrap() };
// Retrieve information of a file.
let file = fw_cfg.find_file("etc/igd-opregion").unwrap();
// Read data from the file.
let data = fw_cfg.read_file(&file);
}
Rust support
The minimum supported Rust version for qemu-fw-cfg
is 1.59.0.
However, testing for x86 currently requires Rust Nightly as it uses
Cargo’s build-std
.
