cpu_tuner

A graphical Linux application for overclocking Intel CPUs.

Preparation

Enable the msr kernel module

You can either do modprobe msr or if you want it permanently enabled you can create the file /etc/modules-load.d/msr.conf containing the word msr on the first line and then reboot.

This is needed because only code running at Ring 0 protection level (the kernel space) can modify the model-specific registers. No userspace program can have access to these register without passing through the kernel.

Install msr-tools

pacman -S msr-tools if you are on Arch Linux. This installs the rdmsr and wrmsr binaries used to communicate with the kernel module.

Compilation

1. Run flutter build linux (with --debug for debug mode).
2. Run cargo build (with --release for release mode) inside cpu_tuner_rs/ to build the shared library.
3. Copy the shared library from cpu_tuner_rs/target/[debug|release]/libcpu_tuner.so to build/linux/[debug|release]/bundle/.
4. Run the executable as root.

Optionally, strip all the shared libraries inside the bundle to greatly reduce their size. I don't know why neither Flutter nor Rust strip the binaries when compiling in release mode.
