- 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.
