got some new HP DL380p G8 for Centos. What's the correct options to disable MSI for the onboard Broadcom NICs?

I tried disable_msi in modprobe.conf.local and it doesn't work.

Thanks Will

  • what version of centos? – Chopper3 Jun 12 '13 at 17:12
  • Have you read this; http://www.parisc-linux.org/~willy/MSI-HOWTO.txt - bear in mind you probably actually have MSI-X rather than plain MSI – Chopper3 Jun 12 '13 at 17:16
  • CentOS 6.4 Thanks for the URL – Billy K Jun 12 '13 at 18:52
  • I wonder if I have to do the same thing to tg3 as bnx2. "Configuring IRQ SMP affinity has no effect on some devices that use MSI with no MSI per-vector masking capability. Examples of such devices include Broadcom NetXtreme Ethernet devices that use the bnx2 driver." – Billy K Jun 12 '13 at 19:12
  • Don't know sorry, can't pretend that I'm not interested in why you want to do this by the way – Chopper3 Jun 12 '13 at 20:08
  • on some older cisco servers, we had bnx2 drivers on the onboard cards. Try to lower the number of interrupts we would deal with. Pin down eth0 and eth1 on cpu0 and cpu1, leaving other cores for Solarflare cards. found that tg3 is default to rss max to 5. Still don't know what's the right parameter, if there's one, to disable it. – Billy K Jul 07 '13 at 23:40
