A utility to identify a cpu and features present. It uses the CPUID instruction and on platforms that support it, feature MSRs

Rust build tools. How you get them depends on platform.

The build tools are provided in the distro simply run the following

sudo dnf install cargo rustfmt clippy

The build tools are provided in the distro simply run the following

sudo apt install cargo

See instructions here They will walk you through installing cargo and any prerequisites.

Simple

cargo build

Cargo will also run it. If you didn't build it, it will also do that.

cargo run -- --help

Cargo will place the executable depending on if it was built as a release or debug build.

./target/debug/cpuinfo --help ./target/release/cpuinfo --help

This is currently a todo item. Until we set it up, cargo clippy is used to lint the code.

Simple rustfmt

cargo fmt

Probably many things ... 2 that come to mind worth mentioning are:

1. CPU Features - The current list was added to make the framework ... work and we need more.
2. Documentation - cargo doc generating a reasonable set from what is there would be nice.

Ideally, this section will grow some github issues or something.

The locations of the manuals do change so, no links here as they maybe broken.

1. Intel - look for "Intel® 64 and IA-32 Architectures Software Developer’s Manual"

• "Volume 2" contains the CPUID instruction return information
• "Volume 3" contains the VMX Features
• "Volume 4" contains information on MSRs

2. AMD - "AMD64 Architecture Programmer’s Manual"

• "Volume 3" Appendix D Contains CPUID information
