I haven't looked at all the new clock/timer code, is there any
utility in having support for more than one clock source?
There is if the main clocksource has some issues where it can't be used.
You mean, having more than one clocksource is *useful* in this case?
On x86 there are lots of different issues with the clocks, so they have
to get switches once in a while. For instance, if the TSC changes
frequencies then it can't be used, or if the TSC stops in different
power states , it can't be used..
Yeah, and there's the rating systems for both clock sources/events.
Anything like that on PowerPC?
Well, the decrementer frequency may change, at least in theory (if the bus
clock changes).
