# Dxe 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. | |
