On SEV-SNP, we accept the HOBs 0-0xA000 and 0x10_0000-0xC00_0000, which takes a couple seconds, which is non-negligible. For VMs that want to boot very fast and still have access to a lot of memory in the long run (e.g., a UEFI app as an enclave or sandbox), I admit it's not my favorite solution. That being said, supporting unaccepted memory in the guest means that the 4GB solution doesn't preclude an accept-on-demand solution in the future in the case that there is demand. -- -Dionna Glaze, PhD (she/her) -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
