+#  Base Timer Library which uses the Time Stamp Counter in the processor.\r
+#\r
+#  Note: There will be 1ms penalty to get TSC frequency every time\r
+#    by waiting for 3579 clocks of the ACPI timer, or 1ms.\r
+#\r
+#  A version of the Timer Library using the processor's TSC.\r
+#  The time stamp counter in newer processors may support an enhancement, referred to as invariant TSC.\r
+#  The invariant TSC runs at a constant rate in all ACPI P-, C-. and T-states.\r
+#  This is the architectural behavior moving forward.\r
+#  TSC reads are much more efficient and do not incur the overhead associated with a ring transition or\r
+#  access to a platform resource.\r
