Linux as Firmware
Tired of reinventing the wheel by implementing drivers for firmware again and again? Not with LinuxBoot!
LinuxBoot is a firmware for modern servers that replaces specific firmware functionality like the UEFI DXE phase with a Linux kernel and runtime.
- 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.
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
