5 bool "Message Signaled Interrupts (MSI and MSI-X)"
7 depends on (X86_LOCAL_APIC && X86_IO_APIC) || IA64
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
19 If you don't know what to do here, say N.
23 depends on PCI && DEBUG_KERNEL
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.
