- ---help---
- 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.

- Say Y here if you want to use the timer interrupt (jiffies) as clock

- ---help---
- Say Y here if you want to use the CPU's cycle counter as clock source.
- This is a cheap and high resolution clock source, but on some
- architectures it is not synchronized on all processors and doesn't
- handle cpu clock frequency changes.
-
- The useable cycle counters are:
-
- x86/x86_64 - Timestamp Counter
- alpha - Cycle Counter
- sparc64 - %ticks register
- ppc64 - Time base
- ia64 - Interval Time Counter
-
- Choose this if your CPU's cycle counter is working properly.
