Message:

HostDrivers/Support: document caller assumptions for SUPR0GetVmxUsability().

File:

trunk/src/VBox/HostDrivers/Support/SUPDrv.cpp

-              r56270
+              r56493
+ *
  * @remarks Must be called with preemption disabled.
+ *          The caller is also expected to check that the CPU is an Intel (or
+ *          VIA) CPU -and- that it supports VT-x.  Otherwise, this function
+ *          might throw a #GP fault as it tries to read/write MSRs that may not
+ *          be present!
