It will be used by userspace to decrypt and mount encrypted drives. So add SVKL table signature and add it to known signatures array support SVKL. You can find details about the SVKL table in TDX specfication titled "Guest-Host-Communication Interface (GHCI) for Intel Trust Domain Extensions (Intel® TDX)", sec 4.4 and in ACPI specification r6.4, sec 5.2.6. https://software.intel.com/content/dam/develop/external/us/en/documents/intel-tdx-guest-hypervisor-communication-interface.pdf Cc: Robert Moore Cc: Erik Kaneda Cc: Rafael J.
