[openib-general] Re: [PATCH] IPoIB splitting CQ, increase both send/recv poll NUM_WC & interval

[Shirley Ma]

Leonid,

> Have you tried to use other SOFTIRQ instead of TASKLET_SOFTIRQ? 
I have looked at the interrupts.h below:

       HI_SOFTIRQ=0,
       TIMER_SOFTIRQ,
       NET_TX_SOFTIRQ,
       NET_RX_SOFTIRQ,
       BLOCK_SOFTIRQ,
       TASKLET_SOFTIRQ

I could't see any softirq we could use for IB completion polling to run 
simultanously on multiple cpus. 
We might need to use work_queues instead.

Can the driver be able to identify sendQ/recvQ completion interrupt? Can 
two tasklets (one for send, one for recv) to be implemented on your 
driver?

Thanks
