This repository contains the source used for the fwupd project to generate a UEFI binary for installing updates using the UpdateCapsule runtime service.
It was originally imported from the combined fwupd project, and is now maintained separately to allow fwupd userspace releases and fwupd-efi UEFI executable releases to follow a different candence.
This UEFI executable is compatible will all fwupd releases from 1_1_X and newer. In these fwupd sustaining releases, the EFI source continues to be distributed, but a new fwupd meson build option -Defi_binary=false is introduced which will allow disabling the compilation of built-in fwupd EFI binary.
The fwupd EFI source has been removed from the releases and is now distributed by this repository.
Hand-building fwupd will perform a subproject checkout of fwupd-efi and build the binary at the same time.
All packagers should generate separate source packages for fwupd and fwupd-efi. In the fwupd package, the subproject behavior should be explicitly disabled using -Defi_binary=false.
fwupd-efi uses the meson system to build EFI executables. Install gnu-efi and then follow these instructions to build and install locally:
meson build
ninja -C build
ninja -C build installThe packager should also specify the SBAT metadata required for the secure boot revocation support. See the specification for more information.
Typically, this will be set as part of the packager build script, e.g.
-Defi_sbat_distro_id="fedora" \
-Defi_sbat_distro_summary="The Fedora Project" \
-Defi_sbat_distro_pkgname="%{name}" \
-Defi_sbat_distro_version="%{version}" \
-Defi_sbat_distro_url="https://src.fedoraproject.org/rpms/%{name}" \
