Low-latency / scheduling latency in 2.5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello

I've searched to no avail the internet to clarify one question:
my current understanding is, that was used to be the low-latency patch
by Andrew Morton is now included (a modified version thereof) in 2.5, as
well as the preemptible kernel patch by Robert Love (credits to Ingo
Molnar and others are due too)? The preemptibility is enabled by a
configuration option, but what about the low- (scheduler-) latency? Is it
just always on, or are they enabled / disabled together or what?

Thanks
Guennadi
