[PATCH v2 09/38] qemu_capabilities: Introduce QEMU_CAPS_DEVICE_UEFI_VARS
Posted by Andrea Bolognani via Devel 12 hours ago 
This capability indicates the availability of the uefi-vars
device.

The actual name of the QEMU device varies slightly depending on
the architecture: it's uefi-vars-x64 on x86_64, uefi-vars-sysbus
on other UEFI architectures (aarch64, riscv64, loongarch64).
