    Subject[RFC PATCH v2 04/69] KVM: TDX: Add TDX "architectural" error codes
    Date
    From: Sean Christopherson <sean.j.christopherson@intel.com>

    Add TDX completion status codes for SEAMCALL and TDG_VP_VMCALL.

    TDX-SEAM uses bits 31:0 to return more information, so these error codes
    for SEAMCALL will only exactly match RAX[63:32]. [1] Section 17.1 Interface
    Function Completion Status Codes
    Completion status codes for TDG.VP.VMCALL is defined in
    [2] Chapter 3 TDG.VP.VMCALL Interface.
