12 bool "Message Signaled Interrupts (MSI and MSI-X)"
14 select GENERIC_MSI_IRQ
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.
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

37 This enables workarounds for various PCI chipset bugs/quirks.

45 Say Y here if you want the PCI core to produce a bunch of debug
46 messages to the system log. Select this if you are having a
47 problem with PCI support and want to see more of what is going on.

52 bool "Enable PCI resource re-allocation detection"
56 Say Y here if you want the PCI core to detect if PCI resource
57 re-allocation needs to be enabled. You can always use pci=realloc=on
58 or pci=realloc=off to override it. It will automatically
59 re-allocate PCI resources if SR-IOV BARs have not been allocated by

97 I/O Virtualization is a PCI feature supported by some devices

108 PRI is the PCI Page Request Interface. It allows PCI devices that are
109 behind an IOMMU to recover from page faults.
114 bool "PCI PASID support"
118 Process Address Space Identifiers (PASIDs) can be used by PCI devices
119 to access more than one IO address space at the same time. To make
120 use of this feature an IOMMU is required which also supports PASIDs.
121 Select this option if you have such an IOMMU and want to compile the
122 driver for it into your kernel.
