[PATCH v2 15/22] target/arm/kvm-rme: Add measurement algorithm property

2024-04-19 Thread Jean-Philippe Brucker
This option selects which measurement algorithm to use for attestation. Supported values are SHA256 and SHA512. Default to SHA512 arbitrarily. SHA512 is generally faster on 64-bit architectures. On a few arm64 CPUs I tested SHA256 is much faster, but that's most likely because they only support ac
