    Subject[PATCH 0/4]: Resolve MSI vs. INTX_DISABLE quirks.

    The forthcoming patches are also available from:

    and clean up the handling of the common quirk wherein setting
    INTX_DISABLE will mistakedly disable MSI generation for some

    For devices without that problem, we want to keep the pci_intx() calls
    in drivers/pci/msi.c because those help protect against devices
    with the opposite problem. Such devices always generate INTX
    interrupts even when MSI is enabled, unless INTX_DISABLE is set.

    Michael, please pay special attention to patch #3. I think I
    picked the correct PCI device IDs to match for the quirk
    (5714* and 5780*) but it's possible we might need more elaborate
    checks here. It at least worked properly for the chips in my
    Niagara system.

    In addition to the Tigon3 cases, I added quirk entries for the
    SB700/800 SATA chips and the IXP SB400 USB controllers.
