+ depends on PCI
+
+config PCI_MSI
+ bool "Message Signaled Interrupts (MSI and MSI-X)"
+ depends on PCI
+ select GENERIC_MSI_IRQ
+ 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_MSI_IRQ_DOMAIN

+
+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_REALLOC_ENABLE_AUTO
+ bool "Enable PCI resource re-allocation detection"
+ depends on PCI
+ help
+ Say Y here if you want the PCI core to detect if PCI resource
+ re-allocation needs to be enabled. You can always use pci=realloc=on
+ or pci=realloc=off to override it. Note this feature is a no-op
+ unless PCI_IOV support is also enabled; in that case it will
+ automatically re-allocate PCI resources if SR-IOV BARs have not
+ been allocated by the BIOS.
+
+ 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 XEN_PCIDEV_FRONTEND
+ tristate "Xen PCI Frontend"
+ depends on PCI && X86 && XEN
+ select PCI_XEN
+ select XEN_XENBUS_FRONTEND
+ default y
+ help
+ The PCI device frontend driver allows the kernel to import arbitrary
+ PCI devices from a PCI backend to support PCI driver domains.
+
+config HT_IRQ
+ bool "Interrupts on hypertransport devices"
+ default y
+ depends on PCI && X86_LOCAL_APIC
+ help
+ This allows native hypertransport devices to use interrupts.
+

+
+config PCI_ATS

+
+config PCI_IOV
+ bool "PCI IOV support"
+ depends on PCI
+ select PCI_ATS
+ 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_PRI
+ bool "PCI PRI support"
+ depends on PCI
+ select PCI_ATS
+ help
+ PRI is the PCI Page Request Interface. It allows PCI devices that are
+ behind an IOMMU to recover from page faults.
+
+ If unsure, say N.
+
+config PCI_PASID
+ bool "PCI PASID support"
+ depends on PCI
+ select PCI_ATS
+ help
+ Process Address Space Identifiers (PASIDs) can be used by PCI devices
+ to access more than one IO address space at the same time. To make
+ use of this feature an IOMMU is required which also supports PASIDs.
+ Select this option if you have such an IOMMU and want to compile the
+ driver for it into your kernel.
+
+ If unsure, say N.
