| d50f6f8b | 2 | # Pei Timer Library which uses the Time Stamp Counter in the processor.\r |

4 | # Note: This library is a sample implementation that depends on chipset ACPI timer. \r |
| 5 | # It may not work on new generation chipset. PcAtChipsetPkg AcpiTimerLib is \r | |
| 6 | # the generic timer library that can replace this one. \r | |
| 7 | #\r | |
| c06ad33e | 8 | # A version of the Timer Library using the processor's TSC.\r |
| 9 | # The time stamp counter in newer processors may support an enhancement, referred to as invariant TSC.\r | |
| 10 | # The invariant TSC runs at a constant rate in all ACPI P-, C-. and T-states.\r | |
| 11 | # This is the architectural behavior moving forward.\r | |
| 12 | # TSC reads are much more efficient and do not incur the overhead associated with a ring transition or\r | |
| 13 | # access to a platform resource.\r | |
