linux-playground

This repository houses some patches to the Linux kernel that I've made just for fun (i.e. shouldn't ever and wouldn't ever be merged), alongside a build system to recompile the kernel as needed and aid with experimentation.

Included patches

• pipefs.patch: Allows pipefs (the filesystem used internally by the kernel for implementing pipes [and also some locking mechanism for processes(?)]) to be mounted in userspace.
• More to come?

Build targets

• all: build the rootfs image and the kernel image
• apply: applies the patches specified in P, e.g. make apply P=patches/pipefs.patch will apply pipefs.patch to the linux local source tree.
• run: runs qemu and tio (for the serial console interface)
• debug: runs gdb
• clean: remove build artifacts and temporary files
• sane: restore the terminal to a sane state (why not?)
