EnterMode: 4 bits represent VTL0 enter mode.
EnterModes: Controls how to enter VTL0.
hcl_cpu_context_aarch64
hcl_cpu_context_x64
hcl_hvcall
hcl_hvcall_setup
hcl_intr_offload_flags: Kernel IPI offloading flags

hcl_kick_cpus_flags
hcl_pfn_range_t
hcl_post_message_direct_t
hcl_run
hcl_set_poll_file
hcl_signal_event_direct_t
hcl_translate_address_info

snp_vp_context
tdx_l2_tsc_deadline_state: L2 TSC deadline state for current VP.
tdx_tdg_vp_enter_exit_info: The register values returned from a TDG.VP.ENTER call. These are readable via mmaping the mshv_vtl driver inside hcl_run, and returned on a run_vp ioctl exit. See the TDX ABI specification for output operands for TDG.VP.ENTER.
tdx_vp_context
tdx_vp_state: Additional VP state that is save/restored across TDG.VP.ENTER.
