# Dxe 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.
