Matthew Wilcox 309e57df7b [PATCH] PCI: Provide a boot parameter to disable MSI 
Several drivers are starting to grow options to disable MSI.  However,
it's often a host chipset issue, not something which individual drivers
should handle.  So we add the pci=nomsi kernel parameter to allow the user
to disable MSI modes for systems we haven't added to the quirk list yet.

PCI configuration

config PCI_MSI bool "Message Signaled Interrupts (MSI and MSI-X)" depends on PCI depends on (X86_LOCAL_APIC && X86_IO_APIC) || IA64 help This allows device drivers to enable MSI (Message Signaled Interrupts). Message Signaled Interrupts enable a device to generate an interrupt using an inbound Memory Write on its PCI bus instead of asserting a device IRQ pin.

   Use of PCI MSI interrupts can be disabled at kernel boot time
   by using the 'pci=nomsi' option.  This disables MSI for the
   entire system.

   If you don't know what to do here, say N.

config PCI_DEBUG bool "PCI Debugging" depends on PCI && DEBUG_KERNEL help Say Y here if you want the PCI core to produce a bunch of debug messages to the system log. Select this if you are having a problem with PCI support and want to see more of what is going on.

  When in doubt, say N.
