| |
The forthcoming patches are also available from:
kernel.org:/pub/scm/linux/kernel/git/davem/msiquirk-2.6.git
and clean up the handling of the common quirk wherein setting INTX_DISABLE will mistakedly disable MSI generation for some devices.
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.
