10 This allows device drivers to enable MSI (Message Signaled
11 Interrupts). Message Signaled Interrupts enable a device to
12 generate an interrupt using an inbound Memory Write on its
13 PCI bus instead of asserting a device IRQ pin.
15 Use of PCI MSI interrupts can be disabled at kernel boot time
16 by using the 'pci=nomsi' option. This disables MSI for the
17 entire system.
19 If you don't know what to do here, say N.
21 config PCI_DEBUG
22 bool "PCI Debugging"
23 depends on PCI && DEBUG_KERNEL
24 help
25 Say Y here if you want the PCI core to produce a bunch of debug
26 messages to the system log. Select this if you are having a
27 problem with PCI support and want to see more of what is going on.
29 When in doubt, say N.
