This needs corresponding KVM patch for TDX [1]. The patch [1] requires more patches to be function. So this patch series is RFC. For those who want to try github repo is available at [2]. Patch series is organized as follows. 1- 5 code refactoring and simple hooks that will be used later 6- 9 introduce kvm type and tdx type. disallow non-usable operations 10-15 wire up necessary TDX kvm ioctl to initialize TD guest 16-24 load TDVF and setup necessary info for TDVF 25-26 prohibit unsupported operations related to SMM 28-29 force x2apic and disable PIC 30-31 allows user to specify sha384 value for TD guest 32-33 add qmp operation to query KVM capability and TD info 34 make reboot action shutdown 35-43 suppress level-trigger/SMI/INIT/SIPI 44 suppress S3/S4 TODO: - gdb support - sanity check of CPUID Changes from v1: - suppress level trigger/SMI/INIT/SIPI related to IOAPIC. - add VM attribute sha384 to TD measurement. - guest TSC Hz specification.
