* [PATCH] PCI: Change MSI to use physical delivery mode alwaysAshok Raj2005-11-10
| | | | | | | | | | | | | | | | | MSI hardcoded delivery mode to use logical delivery mode. 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.

* [PATCH] PCI: automatically set device_driver.ownerLaurent riffard2005-11-10
| | | | | | | | | | | | | | | | | | | | | | | A nice feature of sysfs is that it can create the symlink from the driver to the module that is contained in it.

* [PATCH] pciehp: clean-up how we request control of hotplug hardwarerajesh.shah@intel.com2005-11-10
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch further tweaks how we request control of hotplug controller hardware from BIOS. 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.

* [PATCH] pciehp: request control of each hotplug controller individuallyrajesh.shah@intel.com2005-11-10
| | | | | | | | | | | | | This patch tweaks the way pciehp requests control of the hotplug hardware from BIOS. 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.

* [PATCH] pciehp: reduce dependence on ACPIrajesh.shah@intel.com2005-11-10
| | | | | | | | | | | | | | | | | | | Reduce the PCI Express hotplug driver's dependence on ACPI. 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. Signed-off-by: Rajesh Shah <rajesh.shah@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] PCI: add pci_find_next_capability()Roland Dreier2005-11-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices have more than one capability of the same type. 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. The patch below introduces a new pci_find_next_capability(), which can be used in a loop like for (pos = pci_find_capability(pdev, <ID>); pos; pos = pci_find_next_capability(pdev, pos, <ID>)) { /* ... */ } Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] fix missing includesTim Schmielau2005-10-30
| | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

* [PATCH] PCI: Block config access during BISTBrian King2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some PCI adapters (eg. ipr scsi adapters) have an exposure today in that they issue BIST to the adapter to reset the card. If, during the time it takes to complete BIST, userspace attempts to access PCI config space, the host bus bridge will master abort the access since the ipr adapter does not respond on the PCI bus for a brief period of time when running BIST. On PPC64 hardware, this master abort results in the host PCI bridge isolating that PCI device from the rest of the system, making the device unusable until Linux is rebooted. This patch is an attempt to close that exposure by introducing some blocking code in the PCI code. When blocked, writes will be humored and reads will return the cached value. Ben Herrenschmidt has also mentioned that he plans to use this in PPC power management.

* [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King2005-10-28
| | | | | | | | | | | | | | | | In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

* PCI: be more verbose about resource quirksLinus Torvalds2005-10-25
| | | | | | | | | | When reserving an PCI quirk, note that in the kernel bootup messages. Also, parse the strange PIIX4 device resources - they should get their own PCI resource quirks, but for now just print out what it finds to verify that the code does the right thing.
