The driver is complex for several reasons. Battery charging is manually monitored and controlled. When suspended, the device needs to periodically partially resume, check the charging status and then re-suspend. It does without bothering the higher linux layers as a full resume and re-suspend is unnecessary. The code is carefully written to avoid interrupts or calling code outside the module under these circumstances. It also vets the various wake up sources and monitors the device's power situation. Hooks to limit the backlight intensity and to notify the battery monitoring code of backlight events are connected/added as the backlight is one of the biggest users of power on the device.

This means that the port mutex cannot be held for writing while calling ib_unregister_mad_agent(), or else it will deadlock.

For example, the PCI header for the PathScale InfiniPath looks like: 04:01.0 InfiniBand: Unknown device 1fc1:000d (rev 02) Subsystem: Unknown device 1fc1:000d Flags: bus master, fast devsel, latency 0, IRQ 193 Memory at fea00000 (64-bit, non-prefetchable) [size=2M] Capabilities: [c0] HyperTransport: Slave or Primary Interface Capabilities: [f8] HyperTransport: Interrupt Discovery and Configuration There are _two_ HyperTransport capabilities, and the PathScale driver wants to look at both of them. The current pci_find_capability() API doesn't work for this, since it only allows us to get to the first capability of a given type.

We don't walk the acpi namespace anymore to build a list of bridges and devices. We go to ACPI only to run the _OSC or _OSHP methods to transition control of hotplug hardware from system BIOS to the hotplug driver, and to run the _HPP method to get hotplug device parameters like cache line size, latency timer and SERR/PERR enable from BIOS. Note that one of the side effects of this patch is that pciehp does not automatically enable the hot-added device or its DMA bus mastering capability now. It expects the device driver to do that. This may break some drivers and we will have to fix them as they are reported.

There's a lot of overlap in the information kept, and some of it is never used. This patch consolidates the state information to per-slot and eliminates unused data structures. The biggest change is to eliminate the pci_func structure and the code around managing its lists.

It now tries to invoke the ACPI _OSC method for a specific hotplug controller only, rather than walking the entire acpi namespace invoking all possible _OSC methods under all host bridges. This allows us to gain control of each hotplug controller individually, even if BIOS fails to give us control of some other hotplug controller in the system.

We first search the ACPI namespace corresponding to a specific hotplug controller looking for an _OSC or OSHP method. On failure, we successively move to the ACPI parent object, till we hit the highest level host bridge in the hierarchy. This allows for different types of BIOS's which place the _OSC/OSHP methods at various places in the acpi namespace, while still not encroaching on the namespace of some other root level host bridge. This patch also introduces a new load time option (pciehp_force) that allows us to bypass all _OSC/OSHP checking. Not supporting these methods seems to be be the most common ACPI firmware problem we've run into. This will still _not_ allow the pciehp driver to work correctly if the BIOS really doesn't support pciehp (i.e. if it doesn't generate a hotplug interrupt). Use this option with caution. Some BIOS's may deliberately not build any _OSC/OSHP methods to make sure it retains control the hotplug hardware. Using the pciehp_force parameter for such systems can lead to two separate entities trying to control the same hardware.

It requires that the device_driver.owner is set, what is not the case for many PCI drivers. This patch allows pci_register_driver to set automatically the device_driver.owner for any PCI driver.

Recently x86_64 moved to use physical mode addressing to support physflat mode. With this mode enabled noticed that my eth with MSI werent working. msi_address_init() was hardcoded to use logical mode for i386 and x86_64. So when we switch to use physical mode, things stopped working. Since anyway we dont use lowest priority delivery with MSI, its always directed to just a single CPU. Its safe and simpler to use physical mode always, even when we use logical delivery mode for IPI's or other ioapic RTE's.
