Subject: Configure MSI-X vectors to target different CPUs
Date: Thu, 21 Feb 2008 18:24:47 -0800 (PST)	[thread overview]
Message-ID: <852306.69189.qm@web53803.mail.re2.yahoo.com> (raw)

Hi,

In MSI-HOWTO, it's said:

"Using MSI enables the device functions to support two or more vectors, which can be configured to target different CPUs to increase scalability."

So how can I set up MSI-X vectors to target different CPUs? I want to allocate the same number of MSI-X vectors as CPUs, and equally distribute them to every CPU.

Is it automatically done by Linux when I call pci_enable_msix()? If yes, how? If not, what should I do? My guess is to set the affinity of the interrupts manually. Am I right?

Please CC'ed me (caiying@yahoo.com) answers/comments  in response to this posting. 

Thanks,
Ying
