* [PATCH] PowerPC/PCI Hotplug build breakLinas Vepstas2006-02-01
| | | | | | | | | | | | | | Build break: Building PCI hotplug on PowerPC results in a build break, due to failure to export symbols. Reported today by Dave Jones <davej@redhat.com>: drivers/pci/hotplug/rpaphp.ko needs unknown symbol pcibios_add_pci_devices This patch fixes same problem in drivers/pci tree Previous patch fixes the break in the arch/powerpc tree.

* [PATCH] powerpc/PCI hotplug: shuffle error checking to better location.linas@austin.ibm.com2006-01-31
| | | | | | | | | | | Error checking is scattered through various layers of the dlpar code, leading to a somewhat opaque code structure. This patch consolidates error checking in one routine, simplifying the code a tad. There's also some whitespace cleanup here too.

* [PATCH] PCI Hotplug: shpchp: AMD POGO errata fixKeck, David2006-01-31
| | | | | | | | | | | | | This patch fixes the AMD POGO errata on the hotplug controller where the platform will lock up or reboot if PERR/SERR generation is enabled and a slot is sent an enable command. This fix disables PERR/SERR generation before a slot is sent the enable command by first saving related registers, turning off SERR/PERR generation, enabling the slot, then restoring the registers.

* [PATCH] PCI Hotplug: PCI panic on dlpar add (add pci slot to running partition)linas2006-01-31
| | | | | | | | | | | | | | | | Removing and then adding a PCI slot to a running partition results in a kernel panic. The current code attempts to add iospace for an entire root bus, which is inappropriate, and silently fails. When a pci device tries to use the iospace, a page fault is taken, as the iospace had not been mapped, and of course the page fault cannot be resolved. This only occurs for PCI adapters using pio, which may be why it hadn't been seen earlier (this seems to have been broken for a while). This patch has survived testing of dozens of slot add and removes.

* [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.

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.

| | | | | | | | | | | | | | | | | | | 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>
