+; SKD022: VM Entry That Clears TraceEn May Generate a FUP.
+;
+; If VM entry clears Intel(R) PT (Intel Processor Trace)
+; IA32_RTIT_CTL.TraceEn (MSR 570H, bit 0) while PacketEn is 1 then a
+; FUP (Flow Update Packet) will precede the TIP.PGD (Target IP Packet,
+; Packet Generation Disable). VM entry can clear TraceEn if the
+; VM-entry MSR-load area includes an entry for the IA32_RTIT_CTL MSR.
