| bool "Message Signaled Interrupts (MSI and MSI-X)" |
| depends on ARCH_SUPPORTS_MSI |
| 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 |

| Say Y here if you want the PCI core to produce a bunch of debug |

| bool "Interrupts on hypertransport devices" |
| depends on PCI && X86_LOCAL_APIC && X86_IO_APIC |
| This allows native hypertransport devices to use interrupts. |
