AMD SEV-SNP: Support for attestating initrd

[I. Its]

Hi all,

we are currently working with SEV-SNP to include initrd in attestation report. However, the function sev_add_kernel_loader_hashes() in /qemu/target/i386/sev.c returns false when SEV-SNP is enabled:

if (sev_snp_enabled()) {
  return false;
}

Could someone elaborate on this topic and provide steps to support this kind of attestation? Any hint is also very appreciated.
