- prompt "Packet scheduler clock source"
- default NET_SCH_CLK_GETTIMEOFDAY
- ---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.

-config NET_SCH_CLK_JIFFIES
- bool "Timer interrupt"
- ---help---
- Say Y here if you want to use the timer interrupt (jiffies) as clock
- source. This clock source is fast, synchronized on all processors and
- handles cpu clock frequency changes, but its resolution is too low
- for accurate shaping except at very low speed.
-
-config NET_SCH_CLK_GETTIMEOFDAY
- bool "gettimeofday"
- ---help---
- Say Y here if you want to use gettimeofday as clock source. This clock
- source has high resolution, is synchronized on all processors and
- handles cpu clock frequency changes, but it is slow.
-
- Choose this if you need a high resolution clock source but can't use
- the CPU's cycle counter.
-
-# don't allow on SMP x86 because they can have unsynchronized TSCs.
-# gettimeofday is a good alternative
-config NET_SCH_CLK_CPU
- bool "CPU cycle counter"
- depends on ((X86_TSC || X86_64) && !SMP) || ALPHA || SPARC64 || PPC64 || IA64
- ---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.
