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

| config PCI_LEGACY_PROC |
| bool "Legacy /proc/pci interface" |
| depends on PCI |
| ---help--- |
| This feature enables a procfs file -- /proc/pci -- that provides a |
| summary of PCI devices in the system. |
| |
| This feature has been deprecated as of v2.5.53, in favor of using the |
| tool lspci(8). This feature may be removed at a future date. |
| |
| lspci can provide the same data, as well as much more. lspci is a part of |
| the pci-utils package, which should be installed by your distribution. |
| See <file:Documentation/Changes> for information on where to get the latest |
| version. |
| |
| When in doubt, 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. |
