The LaunchDigest* routines assume that the VMM is EC2. This patch allows these routines to take the VMM type as a parameter instead, allowing measurement for QEMU. Signed-off-by: Jagannathan Raman <jag.raman@oracle.com> Reviewed-by: Ian Chin Wang <ian.chin.wang@oracle.com>
The launch digest should also include the vcpu_signature to match the hardware measurement. This patch adds a vcpu_type parameter to the LaunchDigest* routines, which is used to look up the CPU signature from the existing CpuSigs table. If vcpu_type is unspecified, it defaults to using a signature value of 0. Signed-off-by: Jagannathan Raman <jag.raman@oracle.com> Reviewed-by: Ian Chin Wang <ian.chin.wang@oracle.com>
OVMF hash formatting for JSON needs to be more consistent. The Marshaling routing adds a '0x' prefix, which the unmarshaling routine doesn't account for. This change discards the '0x' prefix when marshaling. Signed-off-by: Jagannathan Raman <jag.raman@oracle.com> Reviewed-by: Ian Chin Wang <ian.chin.wang@oracle.com>
CpuSigs is missing the signature for AMD Genoa processors; this patch adds it. Signed-off-by: Jagannathan Raman <jag.raman@oracle.com> Reviewed-by: Ian Chin Wang <ian.chin.wang@oracle.com>
