2 | # Timer Library which uses the Time Stamp Counter in the processor.\r |
3 | #\r |
4 | # A version of the Timer Library using the processor's TSC.\r |
5 | # The time stamp counter in newer processors may support an enhancement, referred to as invariant TSC.\r |
6 | # The invariant TSC runs at a constant rate in all ACPI P-, C-. and T-states.\r |
7 | # This is the architectural behavior moving forward.\r |
8 | # TSC reads are much more efficient and do not incur the overhead associated with a ring transition or\r |
9 | # access to a platform resource.\r |
