Building a Linux GPU Driver for the M4 Mac Mini in One Month

In a blog post, Cody Hooper shares his experience in building a Linux GPU driver for the M4 Mac Mini, a project he accomplished in just one month. He used the open-source kernel driver framework, DRM, and the LLVM Clang compiler to create a driver that allows him to run Linux on the M4 Mac Mini with a fully functional GPU. The driver is based on the Intel i915 driver and uses the KMS (Kernel Mode Setting) API to interact with the GPU. Hooper's driver also includes support for the GPU's 4K display and power management features. He used the M4 Mac Mini's iMac Pro GPU and a Linux kernel version 5.17 to develop the driver.
