# PCI configuration

config ARCH_SUPPORTS_MSI
        bool
        default n

config PCI_MSI
        bool "Message Signaled Interrupts (MSI and MSI-X)"
        depends on PCI
        depends on ARCH_SUPPORTS_MSI
        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_LEGACY
        bool "Enable deprecated pci_find_* API"
        depends on PCI
        default y
        help
          Say Y here if you want to include support for the deprecated
          pci_find_slot() and pci_find_device() APIs.  Most drivers have
          been converted over to using the proper hotplug APIs, so this
          option serves to include/exclude only a few drivers that are
          still using this API.

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.

config HT_IRQ
        bool "Interrupts on hypertransport devices"
        default y
        depends on PCI && X86_LOCAL_APIC && X86_IO_APIC
        help
           This allows native hypertransport devices to use interrupts.

           If unsure say Y.
