- 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 Y.
- 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 PCI_STUB
- tristate "PCI Stub driver"
- depends on PCI
- help
- Say Y or M here if you want be able to reserve a PCI device
- when it is going to be assigned to a guest operating system.
- 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.
- config PCI_IOV
- bool "PCI IOV support"
- depends on PCI
- help
- I/O Virtualization is a PCI feature supported by some devices
- which allows them to create virtual devices which share their
- physical resources.
- If unsure, say N.
- config PCI_IOAPIC
- bool
- depends on PCI
- depends on ACPI
- depends on HOTPLUG
- default y
