| * [PATCH] PCI: reverse pci config space restore orderYu, Luming2006-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to Intel ICH spec, there are several rules that Base Address should be programmed before IOSE (PCICMD register ) enabled. For example ICH7: 12.1.3 SATA : the base address register for the bus master register should be programmed before this bit is set. 11.1.3: PCICMD (USB): The base address register for USB should be programmed before this bit is set. .... To make sure kernel code follow this rule , and prevent unnecessary confusion. I proposal this patch.

| * [PATCH] PCI: Error handling on PCI device resumeJean Delvare2006-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently don't handle errors properly when resuming a PCI device: * In pci_default_resume() we capture the error code returned by pci_enable_device() but don't pass it up to the caller. Introduced by commit 95a629657dbe28e44a312c47815b3dc3f1ce0970 * In pci_resume_device(), the errors possibly returned by the driver's .resume method or by the generic pci_default_resume() function are ignored.

* [PATCH] pci: correctly allocate return buffers for osc callsKristen Accardi2006-05-21
| | | | | | | | | | | | | | | | | | The OSC set and query functions do not allocate enough space for return values, and set the output buffer length to a false, too large value. This causes the acpi-ca code to assume that the output buffer is larger than it actually is, and overwrite memory when copying acpi return buffers into this caller provided buffer. In some cases this can cause kernel oops if the memory that is overwritten is a pointer. This patch will change these calls to use a dynamically allocated output buffer, thus allowing the acpi-ca code to decide how much space is needed.

* [PATCH] VIA quirk fixup, additional PCI IDsChris Wedgwood2006-05-15
| | | | | | | | | | | | | | | | | | An earlier commit (75cf7456dd87335f574dcd53c4ae616a2ad71a11) changed an overly-zealous PCI quirk to only poke those VIA devices that need it. However, some PCI devices were not included in what I hope is now the full list. Consequently we're failing to run the quirk on all machines which need it, causing IRQ routing failures. This should I hope correct this. Thanks to Masoud Sharbiani <masouds@masoud.ir> for pointing this out and testing the fix.

This is bad, since hot-capable slots can be added after boot to a purely virtual POWER partition. This is also bad because DLPAR I/O operations depend on the rpaphp module.

* [PATCH] acpiphp: add dock event handlingKristen Accardi2006-03-23
| | | | | | | | | | | | | | | | | | | | These patches add generic dock event handling to acpiphp. If there are pci devices that need to be inserted/removed after the dock event, the event notification will be handed down to the normal pci hotplug event handler in acpiphp so that new bridges/devices can be enumerated. Because some dock stations do not have pci bridges or pci devices that need to be inserted after a dock, acpiphp will remain loaded to handle dock events even if no hotpluggable pci slots are discovered. You probably need to have the pci=assign-busses kernel parameter enabled to use these patches, and you may not allow ibm_acpi to handle docking notifications and use this patch.

* [PATCH] PCI: PCI/Cardbus cards hidden, needs pci=assign-busses to fixBernhard Kaindl2006-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "In some cases, especially on modern laptops with a lot of PCI and cardbus bridges, we're unable to assign correct secondary/subordinate bus numbers to all cardbus bridges due to BIOS limitations unless we are using "pci=assign-busses" boot option." -- Ivan Kokshaysky (from a patch comment) Without it, Cardbus cards inserted are never seen by PCI because the parent PCI-PCI Bridge of the Cardbus bridge will not pass and translate Type 1 PCI configuration cycles correctly and the system will fail to find and initialise the PCI devices in the system. Reference: PCI-PCI Bridges: PCI Configuration Cycles and PCI Bus Numbering: http://www.science.unitn.it/~fiorella/guidelinux/tlk/node72.html The reason for this is that: ``All PCI busses located behind a PCI-PCI bridge must reside between the secondary bus number and the subordinate bus number (inclusive).'' "pci=assign-busses" makes pcibios_assign_all_busses return 1 and this turns on PCI renumbering during PCI probing. Alan suggested to use DMI automatically set assign-busses on problem systems. The only question for me was where to put it. I put it directly before scanning PCI bus into pcibios_scan_root() because it's called from legacy, acpi and numa and so it can be one place for all systems and configurations which may need it. AMD64 Laptops are also affected and fixed by assign-busses, and the code is also incuded from arch/x86_64/pci/ that place will also work for x86_64 kernels, I only ifdef'-ed the x86-only Laptop in this example. Affected and known or assumed to be fixed with it are (found by googling): * ASUS Z71V and L3s * Samsung X20 * Compaq R3140us and all Compaq R3000 series laptops with TI1620 Controller, also Compaq R4000 series (from a kernel.org bugreport) * HP zv5000z (AMD64 3700+, known that fixup_parent_subordinate_busnr fixes it) * HP zv5200z * IBM ThinkPad 240 * An IBM ThinkPad (1.8 GHz Pentium M) debugged by Pavel Machek gives the correspondig message which detects the possible problem. * MSI S260 / Medion SIM 2100 MD 95600 The patch also expands the "try pci=assign-busses" warning so testers will help us to update the DMI table.

* [PATCH] shpchp: Fix slot state handlingKenji Kaneshige2006-03-23
| | | | | | | | | | | | | | | | | | | | | | | | Current SHPCHP driver doesn't care about the confliction between hotplug operation via sysfs and hotplug operation via attention button. So if those ware conflicted, slot could be an unexpected state. This patch changes SHPCHP driver to handle slot state properly. With this patch, slot events are handled according to the current slot state as shown at the Table below. Table. Slot States and Event Handling ========================================================================= Slot State Event and Action ========================================================================= STATIC - Go to POWERON state if user initiates (Slot enabled, insertion request via sysfs Slot disabled) - Go to POWEROFF state if user initiates removal request via sysfs - Go to BLINKINGON state if user presses attention button when the slot is disabled - Go to BLINKINGOFF state if user presses attention button when the slot is enabled
* [PATCH] shpchp: event handling reworkKenji Kaneshige2006-03-23
| | | | | | | | | | | | | | The event handler of SHPCHP driver is unnecessarily very complex. In addition, current event handler can only a fixed number of events at the same time, and some of events would be lost if several number of events happened at the same time. This patch simplify the event handler by using 'work queue', and it also fix the above-mentioned issue.

Agreed, looks like an accident. The patch [1] originally came from Kip Walker (Broadcom back then) between 2.6.0-test3 and 2.6.0-test4. As I recall it was supposed to fix an issue with with PCI aborts being signalled by the PCI bridge of the Broadcom BCM1250 family of SOCs when probing behind pci_scan_bridge. It is undeseriable to disable PCI_BRIDGE_CTL_MASTER_ABORT in pci_{read,write)_config_* and the behaviour wasn't considered a bug in need of a workaround, so this was put in probe.c. I don't have an affected system at hand, so can't really test but I propose something like the below patch.

* [PATCH] shpchp - Fix incorrect return value of interrupt handlerKenji Kaneshige2006-03-23
| | | | | | | | | | | | | | | | | | Current SHPCHP driver has a bug in its interrupt handler which cause "IRQ #: nobody cared" oops. This problem can be reproduced easily by the following operation. # cd /sys/bus/pci/slots/<slot#> # while true; do echo 1 > attention ; done & The reason is that when command complete interrupt is raised, current SHPCHP driver's interrupt handler returns IRQ_NONE regardless of if the interrupt is handled or not.
