Crate with an example of a kernel module in Rust
This repo is a Makefile with a Rust project that, using Kbuild, the kernel's build system, will generate
a kernel module file named parrot.ko.
The kernel module creates a char device that on every read() call, will return a new frame of an
ASCII art party parrot in your terminal, which ultimately makes an animation appear when used with cat.
I gave a more in depth explanation of the process for creating this kernel module at DevConf.cz 2020. Since then, I was contacted by the Rust for Linux effort. As a result of the great work they've done, I've migrated this kernel module over to use the Rust for Linux kernel API.
# Follow https://github.com/Rust-for-Linux/linux/blob/rust/Documentation/rust/quick-start.rst
# Build and load the kernel module
make
sudo insmod parrot.ko
# Party hard!
sudo cat /dev/parrot
The frames for the parrot are from parrot.live.
parrot.live appears to have taken them from terminal-parrot.
That project states that the frames came from jp2a.
