The kmemcache is not the worst possible option but note that the objects you're allocating (with zeroing) are 512+ bytes. That's pretty large, when most packets will not have full 16 fragments. Ring buffer would allow to better match the allocation size to the packets. Not to mention that it can be done fully locklessly.I modified the implementation to use a circular ring buffer for TX and RX. It seems to be working in initial testing and now running perf tests. Just had one question on when to submit v6 ? Wait till dmaengine patches([01/10-[07/10] is part of net-next? Or can I send it now also.
Assuming Linus cuts final this Sunday - after Sept 10th. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
