So, does it make sense to control RX smp affinity from /proc/irq/*/smp_affinity on multiqueue adapters with RSS support? thanks, Sebastien ________________________________ De : Jesper Dangaard Brouer <hawk@...u.dk> À : Robert Olsson <robert@...ur.slu.se> Cc : David Miller <davem@...emloft.net>; netdev@...r.kernel.org; Robert.Olsson@...a.slu.se Envoyé le : Mardi, 25 Novembre 2008, 16h58mn 06s Objet : Re: [PATCH] Naming interrupt vectors/niu On Tue, 25 Nov 2008, Robert Olsson wrote: > A patch to put names on the niu interrupt vectors according the syntax below. > This is needed to assign correct affinity. > > > So on a multiqueue card with 2 RX queues and 2 TX queues we'd > > have names like: > > > > eth0-rx-0 > > eth0-rx-1 > > eth0-tx-0 > > eth0-tx-1 > > > Signed-off-by: Robert Olsson <robert.olsson@....uu.se> Tested-by: Jesper Dangaard Brouer <jdb@...x.dk> I have tested the patch and it also works on the Quad 1G SUN NIC. I really like the idea behind the patch, as it makes it a lot easier to get the smp affinity right... Hilsen Jesper Brouer -- ------------------------------------------------------------------- MSc.
