Linux as Firmware

Tired of reinventing the wheel by implementing drivers for firmware again and again?
Not with LinuxBoot!

What?

LinuxBoot is a firmware for modern servers that replaces specific firmware functionality like the UEFI DXE phase with a Linux kernel and runtime.

Why?

Improves boot reliability by replacing lightly-tested firmware drivers with hardened Linux drivers.
Improves boot time by removing unnecessary code. Typically makes boot 20 times faster.
Allows customization of the initrd runtime to support site-specific needs (both device drivers as well as custom executables).
Proven approach for almost 20 years in military, consumer electronics, and supercomputing systems – wherever reliability and performance are paramount.

Getting Started

git clone https://github.com/linuxboot/linuxboot
cd linuxboot
make \
	     BOARD=qemu \
	     KERNEL=../path/to/bzImage \
	     INITRD=../path/to/initrd.cpio.xz \
	     config
make

The kernel must be built with CONFIG_EFI_BDS. Follow further instructions on our GitHub.

LinuxBoot Book

The official documentation for LinuxBoot is the LinuxBoot Book, where you can find information on how LinuxBoot works, how to build the various flavours (e.g. coreboot/LinuxBoot or UEFI PEI/LinuxBoot), the u-root ramfs builder, etc.

Fortnightly meeting

We meet every two weeks to discuss about the latest news, upcoming talks and events, and so on. The meeting is open and everyone is welcome!
