| 9 | This allows device drivers to enable MSI (Message Signaled | ||
| 10 | Interrupts). Message Signaled Interrupts enable a device to | ||
| 11 | generate an interrupt using an inbound Memory Write on its | ||
| 12 | PCI bus instead of asserting a device IRQ pin. | ||
| 13 | |||
| 14 | If you don't know what to do here, say N. | ||
| 15 | |||
| 16 | config PCI_LEGACY_PROC | ||
| 17 | bool "Legacy /proc/pci interface" | ||
| 18 | depends on PCI | ||
| 19 | ---help--- | ||
| 20 | This feature enables a procfs file -- /proc/pci -- that provides a | ||
| 21 | summary of PCI devices in the system. | ||
| 22 | |||
| 23 | This feature has been deprecated as of v2.5.53, in favor of using the | ||
| 24 | tool lspci(8). This feature may be removed at a future date. | ||
| 25 | |||
| 26 | lspci can provide the same data, as well as much more. lspci is a part of | ||
| 27 | the pci-utils package, which should be installed by your distribution. | ||
| 28 | See <file:Documentation/Changes> for information on where to get the latest | ||
| 29 | version. | ||
| 30 | |||
| 31 | When in doubt, say N. | ||
| 32 | |||
| 33 | config PCI_NAMES | ||
| 34 | bool "PCI device name database" | ||
| 35 | depends on PCI | ||
| 36 | ---help--- | ||
| 37 | By default, the kernel contains a database of all known PCI device | ||
| 38 | names to make the information in /proc/pci, /proc/ioports and | ||
| 39 | similar files comprehensible to the user. | ||
| 40 | |||
| 41 | This database increases size of the kernel image by about 80KB. This | ||
| 42 | memory is freed after the system boots up if CONFIG_HOTPLUG is not set. | ||
| 43 | |||
| 44 | Anyway, if you are building an installation floppy or kernel for an | ||
| 45 | embedded system where kernel image size really matters, you can disable | ||
| 46 | this feature and you'll get device ID numbers instead of names. | ||
| 47 | |||
| 48 | When in doubt, say Y. | ||
| 49 | |||
| 50 | config PCI_DEBUG | ||
| 51 | bool "PCI Debugging" | ||
| 52 | depends on PCI && DEBUG_KERNEL | ||
| 53 | help | ||
| 54 | Say Y here if you want the PCI core to produce a bunch of debug | ||
| 55 | messages to the system log. Select this if you are having a | ||
| 56 | problem with PCI support and want to see more of what is going on. | ||
| 57 | |||
