p9cpu is an implementation of the Plan 9 cpu command for Linux, similar to u-root/cpu. Check the CPU chapter of the LinuxBoot book for more details. Compared with the original Plan 9 cpu and the Go version u-root/cpu, p9cpu is written in Rust and based on tokio. It uses gRPC for the underlying transport.
