#  Pei Timer Library which uses the Time Stamp Counter in the processor.
#
#  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.
