PCI: Add support for PASID capability

2011-10-14T16:05:35Z

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

2011-10-14T16:05:34Z

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. Reviewed-by: Bjorn Helgaas Signed-off-by: Joerg Roedel Signed-off-by: Jesse Barnes

PCI: add latency tolerance reporting enable/disable support

2011-05-11T22:18:53Z

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. Signed-off-by: Jesse Barnes

PCI: add OBFF enable/disable support

2011-05-11T22:18:48Z

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

2011-05-11T22:18:40Z

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. Signed-off-by: Jesse Barnes

PCI/PCIe: Clear Root PME Status bits early during system resume

2010-12-23T20:54:03Z

I noticed that PCI Express PMEs don't work on my Toshiba Portege R500 after the system has been woken up from a sleep state by a PME (through Wake-on-LAN). After some investigation it turned out that the BIOS didn't clear the Root PME Status bit in the root port that received the wakeup PME and since the Requester ID was also set in the port's Root Status register, any subsequent PMEs didn't trigger interrupts. This problem can be avoided by clearing the Root PME Status bits in all PCI Express root ports during early resume. For this purpose, add an early resume routine to the PCIe port driver and make this driver be always registered, even if pci_ports_disable is set (in which case the driver's only function is to provide the early resume callback).
