+Subject: [PATCH] x86/tdx: Add tdx_mcall_rtmr_extend() interface
+
+TDX Guest exposes 1 MRTD and 3 RTMR registers to record the build and
+boot measurements of the VM. It is similar to PCR registers in TPM
+space. This measurement data will be used to implement security
+features like attestation, trusted boot, etc.
+
+To facilitate RTMR register update, the TDX Module provides support for
+TDG.MR.RTMR.EXTEND TDCALL  which can be used to securely extend the
+RTMR registers.
+
+Add helper function to update RTMR registers. It will be used by the
+TDX guest driver in enabling RTMR support.
