TD partitioning may require few changes to existing TDCALLs. These APIs are listed below,

  • Existing API Changes:
    • Add a return type indicating success and failure for tdvmcall_wrmsr, tdvmcall_rdmsr.
    • Extend TdInfo struct to add vcpu_index field.
      • TdInfo stores the result from the tdcall tdcall_get_td_info. vcpu_index is one of the values returned in R9 bit0 ~ 31. Save this returned vcpu_index in TdInfo.
