NVRAM Testing

Build Requirements

Fedora/CentOS:

sudo dnf install guestfs-tools make libvirt qemu-system-x86-core edk2-ovmf
sudo dnf install python3-lxml python3-requests
sudo dnf copr enable rhughes/fwupd
sudo dnf update fwupd

Adding Models

• run ./nvram.py add-current in the parent directory. A new directory in format of VENDOR-FAMILY-MODEL of the current machine is created with EFI variables containing PK, KEK and DB certificates and DB exclusion lists are created along with custom_VARS.builder.xml file. For the time being, an old DBX is added without the info gathered from the machine being used
• Adjust the custom_VARS.builder.xml as needed to include the suitable certificates
• Build a custom_VARS.fd by running ../nvram.py build custom_VARS.fd
• Run the emulator using ../nvram.py run
• Commit the raw only, for instance git add *.builder.xml PK* KEK* db*

DBX

An old DBX is included in the repo but you can get it as well from the LVFS using:

wget https://fwupd.org/downloads/093e6913dfecefbdaa9374a2e1caee7bf7e74c7eda847624e456e344884ba5f6-DBXUpdate-20241101-x64.cab

You'll probably also need to install gcab to unpack it:

gcab -x *DBXUpdate-20241101-x64.cab
