NVRAM Testing

Build Requirements

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

Adding Models

• run ./nvram.py dump in the parent directory. A new directory in format of VENDOR-FAMILY-MODEL is created
• enter the new directory
• Extract the varialbes using ../nvram.py extract
• Build some custom_*.builder.xml with the certs you want to include in the NVRAM
• 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

You can get an old DBX 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
