User:ZyMOS/Howto configure the linux kernel / drivers / pci


 * PCI configuration
 * PCI configuration


 * Option: PCI_MSI
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "Message Signaled Interrupts (MSI and MSI-X)"
 * depends on PCI
 * depends on (X86_LOCAL_APIC && X86_IO_APIC) || IA64
 * 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.


 * Option: PCI_LEGACY_PROC
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "Legacy /proc/pci interface"
 * depends on PCI
 * 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  for information on where to get the latest version.
 * When in doubt, say N.


 * Option: PCI_DEBUG
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "PCI Debugging"
 * depends on PCI && DEBUG_KERNEL
 * 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.
