2024-06-05i386/sev: Allow measured direct kernel boot on SNPDov Murik
In SNP, the hashes page designated with a specific metadata entry published in AmdSev OVMF. Therefore, if the user enabled kernel hashes (for measured direct boot), QEMU should prepare the content of hashes table, and during the processing of the metadata entry it copy the content into the designated page and encrypt it. Note that in SNP (unlike SEV and SEV-ES) the measurements is done in whole 4KB pages. Therefore QEMU zeros the whole page that includes the hashes table, and fills in the kernel hashes area in that page, and then encrypts the whole page. The rest of the page is reserved for SEV launch secrets which are not usable anyway on SNP. If the user disabled kernel hashes, QEMU pre-validates the kernel hashes page as a zero page.
