 ## @file
 #  Pei Timer Library which uses the Time Stamp Counter in the processor.
 #
 #  Note: This library is a sample implementation that depends on chipset ACPI timer.
 #    It may not work on new generation chipset. PcAtChipsetPkg AcpiTimerLib is
 #    the generic timer library that can replace this one.
 #
 #  A version of the Timer Library using the processor's TSC.
 #  The time stamp counter in newer processors may support an enhancement, referred to as invariant TSC.
 #  The invariant TSC runs at a constant rate in all ACPI P-, C-. and T-states.
 #  This is the architectural behavior moving forward.
 #  TSC reads are much more efficient and do not incur the overhead associated with a ring transition or
 #  access to a platform resource.
