   2 #  Pei Timer Library which uses the Time Stamp Counter in the processor.
   3 #
   4 #  A version of the Timer Library using the processor's TSC.
   5 #  The time stamp counter in newer processors may support an enhancement, referred to as invariant TSC.
   6 #  The invariant TSC runs at a constant rate in all ACPI P-, C-. and T-states.
   7 #  This is the architectural behavior moving forward.
   8 #  TSC reads are much more efficient and do not incur the overhead associated with a ring transition or
   9 #  access to a platform resource.
