 15         help
 16            This allows device drivers to enable MSI (Message Signaled
 17            Interrupts).  Message Signaled Interrupts enable a device to
 18            generate an interrupt using an inbound Memory Write on its
 19            PCI bus instead of asserting a device IRQ pin.
 20 
 21            Use of PCI MSI interrupts can be disabled at kernel boot time
 22            by using the 'pci=nomsi' option.  This disables MSI for the
 23            entire system.
 24 
 25            If you don't know what to do here, say Y.

 36           Say Y here if you want the PCI core to produce a bunch of debug
 37           messages to the system log.  Select this if you are having a
 38           problem with PCI support and want to see more of what is going on.
 39 
 40           When in doubt, say N.

 45         help
 46           Say Y here if you want the PCI core to detect if PCI resource
 47           re-allocation needs to be enabled. You can always use pci=realloc=on
 48           or pci=realloc=off to override it.  Note this feature is a no-op
 49           unless PCI_IOV support is also enabled; in that case it will
 50           automatically re-allocate PCI resources if SR-IOV BARs have not
 51           been allocated by the BIOS.
 52 
 53           When in doubt, say N.

 71           The PCI device frontend driver allows the kernel to import arbitrary

 94           I/O Virtualization is a PCI feature supported by some devices
 95           which allows them to create virtual devices which share their
 96           physical resources.
 97 
 98           If unsure, say N.

105           PRI is the PCI Page Request Interface. It allows PCI devices that are
106           behind an IOMMU to recover from page faults.

115           Process Address Space Identifiers (PASIDs) can be used by PCI devices
116           to access more than one IO address space at the same time. To make
117           use of this feature an IOMMU is required which also supports PASIDs.
118           Select this option if you have such an IOMMU and want to compile the
119           driver for it into your kernel.
