Greg Kroah-Hartman has noted that the Linux Foundation has joined the UEFI.org group. With his new UEFI dealings, he's decided to better document the steps needed to build and boot a self-signed Linux kernel that will work on UEFI SecureBoot enabled systems.
Building a proper kernel with UEFI support requires a few kernel configuration options to be enabled and for a simple setup a boot loader isn't even needed but the kernel can be booted as an EFI binary from a UEFI BIOS. There's also other processes involved with generating and managing your own keys.
