SEV-SNP vTOM guest on Hyper-V. A vTOM guest basically splits the address space in two parts: encrypted and unencrypted. The use case being running unmodified guests on the Hyper-V confidential computing hypervisor - Double-buffer messages between the guest and the hardware PSP device so that no partial buffers are copied back'n'forth and thus potential message integrity and leak attacks are possible - Name the return value the sev-guest driver returns when the hw PSP device hasn't been called, explicitly - Cleanups -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAmRGl8gACgkQEsHwGGHe VUoEDhAAiw4+2nZR7XUJ7pewlXG7AJJZsVIpzzcF6Gyymn0LFCyMnP7O3snmFqzz aik0q2LzWrmDQ3Nmmzul0wtdsuW7Nik6BP9oF3WnB911+gGbpXyNWZ8EhOPNzkUR 9D8Sp6f0xmqNE3YuzEpanufiDswgUxi++DRdmIRAs1TTh4bfUFWZcib1pdwoqSmR oS3UfVwVZ4Ee2Qm1f3n3XQ0FUpsjWeARPExUkLEvd8XeonTP+6aGAdggg9MnPcsl 3zpSmOpuZ6VQbDrHxo3BH9HFuIUOd6S9PO++b9F6WxNPGEMk7fHa7ahOA6HjhgVz 5Da3BN16OS9j64cZsYHMPsBcd+ja1YmvvZGypsY0d6X4d3M1zTPW+XeLbyb+VFBy SvA7z+JuxtLKVpju65sNiJWw8ZDTSu+eEYNDeeGLvAj3bxtclJjcPdMEPdzxmC5K eAhmRmiFuVM4nXMAR6cspVTsxvlTHFtd5gdm6RlRnvd7aV77Zl1CLzTy8IHTVpvI t7XTbtjEjYc0pI6cXXptHEOnBLjXUMPcqgGFgJYEauH6EvrxoWszUZD0tS3Hw80A K+Rwnc70ubq/PsgZcF4Ayer1j49z1NPfk5D4EA7/ChN6iNhQA8OqHT1UBrHAgqls 2UAwzE2sQZnjDvGZghlOtFIQUIhwue7m93DaRi19EOdKYxVjV6U= =ZAw9 -----END PGP SIGNATURE----- Merge tag 'x86_sev_for_v6.4_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 SEV updates from Borislav Petkov: - Add the necessary glue so that the kernel can run as a confidential SEV-SNP vTOM guest on Hyper-V.
