[PATCH 0/2] Improved support for AMD SEV firmware loading

2022-01-13 Thread Daniel P . Berrangé
The AMD SEV build of EDK2 only emits a single file, intended to be mapped readonly. There is explicitly no separate writable VARS store for persisting non-volatile firmware variables. This can be used with QEMU's traditional pflash configuration mechanism by only populating pflash0, leaving pflash
