- Unless QEMU is configured with
--disable-blobs,make installwill install UEFI platform firmware binaries, and matching variable store templates, at$prefix/share/qemu/edk2-*.fd.- These files are built from the edk2 project's ArmVirtPkg and OvmfPkg firmware platforms, and the edk2 project's OpenSSL submodule.
- They are documented (and exposed to virt management applications) through JSON files in
$prefix/share/qemu/firmware/. - The schema definition for the JSON descriptors is located at
docs/interop/firmware.jsonin the QEMU source tree.
