- Packet schedulers need a monotonic clock that increments at a static
- rate. The kernel provides several suitable interfaces, each with
- different properties:
-
- - high resolution (us or better)
- - fast to read (minimal locking, no i/o access)
- - synchronized on all processors
- - handles cpu clock frequency changes
-
- but nothing provides all of the above.

- This is a cheap and high resolution clock source, but on some

- The useable cycle counters are:
-
- x86/x86_64 - Timestamp Counter
- alpha - Cycle Counter
