| |
Hi,
I'm trying to compare the performance of some networking code (throughput and latency when receiving various volumes of UDP streams) between a preemptible and non-preemptible 2.6.24 kernel, and was wondering if it is possible to temporarily disable preemption on a running preemptible kernel. Is it just a matter of loading a module which calls preempt_enable() at load and preempt_disable() at unload - or is that too naive? Is there an existing way of doing this?
thanks,
Matthew.
