  13            This allows device drivers to enable MSI (Message Signaled
  14            Interrupts).  Message Signaled Interrupts enable a device to
  15            generate an interrupt using an inbound Memory Write on its
  16            PCI bus instead of asserting a device IRQ pin.
  17
  18            Use of PCI MSI interrupts can be disabled at kernel boot time
  19            by using the 'pci=nomsi' option.  This disables MSI for the
  20            entire system.

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

  26         depends on PCI && DEBUG_KERNEL
  27         help
  28           Say Y here if you want the PCI core to produce a bunch of debug
  29           messages to the system log.  Select this if you are having a
  30           problem with PCI support and want to see more of what is going on.
  31
  32           When in doubt, say N.
  33
  34 config HT_IRQ
  35         bool "Interrupts on hypertransport devices"
  36         default y
  37         depends on PCI && X86_LOCAL_APIC && X86_IO_APIC
  38         help
  39            This allows native hypertransport devices to use interrupts.
  40
  41            If unsure say Y.
