Fix up conflicts in drivers/pci/msi.c and include/linux/pci_regs.h due
to the same patches being applied in other branches.

PCI: Fix PCI_EXP_TYPE_RC_EC value

2012-01-06T20:10:32+00:00

Spec shows this as 1010b = 0xa

PCI: Fix PRI and PASID consistency

2012-01-06T20:10:26+00:00

These are extended capabilities, rename and move to proper
group for consistency.

PCI: More PRI/PASID cleanup

2011-12-05T18:22:15+00:00

More consistency cleanups.  Drop the _OFF, separate and indent
CTRL/CAP/STATUS bit definitions.  This helped find the previous
mis-use of bit 0 in the PASID capability register.

PCI: Add support for PASID capability

2011-10-14T16:05:35+00:00

Devices supporting Process Address Space Identifiers
(PASIDs) can use an IOMMU to access multiple IO address
spaces at the same time. A PCIe device indicates support for
this feature by implementing the PASID capability. This
patch adds support for the capability to the Linux kernel.

PCI: Add implementation for PRI capability

2011-10-14T16:05:34+00:00

Implement the necessary functions to handle PRI capabilities
on PCIe devices. With PRI devices behind an IOMMU can signal
page fault conditions to software and recover from such
faults.

PCI: add latency tolerance reporting enable/disable support

2011-05-11T22:18:53+00:00

Latency tolerance reporting allows devices to send messages to the root
complex indicating their latency tolerance for snooped & unsnooped
memory transactions.  Add support for enabling & disabling this
feature, along with a routine to set the max latencies a device should
send upstream.

PCI: add OBFF enable/disable support

2011-05-11T22:18:48+00:00

OBFF (optimized buffer flush/fill), where supported, can help improve
energy efficiency by giving devices information about when interrupts
and other activity will have a reduced power impact.  It requires
support from both the device and system (i.e. not only does the device
need to respond to OBFF messages, but the platform must be capable of
generating and routing them to the end point).

PCI: add ID-based ordering enable/disable support

2011-05-11T22:18:40+00:00

Add support to allow drivers to enable/disable ID-based ordering.  Where
supported, ID-based ordering can significantly improve the latency of
individual requests by preventing them from queueing up behind unrelated
traffic.
