Subject: skb processing in SMP kernel
Date: Wed, 14 Nov 2007 21:14:37 +0100 [thread overview]
Message-ID: <20071114211437.7f4c79d2@catlap> (raw)
Hi there,
I'm looking at file /usr/src/linux/net/core/dev.c
function "int netif_rx(struct sk_buff *skb)"
and following line:
queue = &__get_cpu_var(softnet_data);
Is it possible to put skb into the queue of another CPU then the one
servicing the interrupt? (Disclaimer: Yeah, I know it's probably not
the smartest thing to do because of locks and cache line bounces). How
could it be accomplished? Any lead, comment, link appreciated.
pozdrawiam
