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 Use of PCI MSI interrupts can be disabled at kernel boot time 15 by using the 'pci=nomsi' option. This disables MSI for the 16 entire system. 17 18 If you don't know what to do here, say N. 19 20config PCI_DEBUG 21 bool "PCI Debugging" 22 depends on PCI && DEBUG_KERNEL 23 help 24 Say Y here if you want the PCI core to produce a bunch of debug 25 messages to the system log.
