config ARCH_SUPPORTS_MSI
bool
default n
config PCI_MSI
bool "Message Signaled Interrupts (MSI and MSI-X)"
depends on PCI
depends on ARCH_SUPPORTS_MSI
help
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.
Use of PCI MSI interrupts can be disabled at kernel boot time
by using the 'pci=nomsi' option. This disables MSI for the
entire system.
If you don't know what to do here, say N.
config PCI_LEGACY
bool "Enable deprecated pci_find_* API"
depends on PCI
default y
help
Say Y here if you want to include support for the deprecated
pci_find_slot() and pci_find_device() APIs. Most drivers have
been converted over to using the proper hotplug APIs, so this
option serves to include/exclude only a few drivers that are
still using this API.
config PCI_DEBUG
bool "PCI Debugging"
depends on PCI && DEBUG_KERNEL
help
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.
config HT_IRQ
bool "Interrupts on hypertransport devices"
default y
depends on PCI && X86_LOCAL_APIC && X86_IO_APIC
help
This allows native hypertransport devices to use interrupts.
If unsure say Y.
