2012-11-30s390/pci: PCI hotplug support via SCLPJan Glauber
Add SCLP PCI configure/deconfigure and implement a PCI hotplug controller (s390_pci_hpc). The hotplug controller creates a slot for every PCI function in stand-by or configured state. The PCI functions are named after the PCI function ID (fid). By writing to the power attribute in /sys/bus/pci/slots/<fid>/power the PCI function is moved to stand-by or configured state. If moved to the configured state the device is automatically scanned by the s390 PCI layer.

2012-09-24PCI: acpiphp: Handle PCIe ports without native hotplug capabilityJiang Liu
Commit 0d52f54e2ef64c189dedc332e680b2eb4a34590a (PCI / ACPI: Make acpiphp ignore root bridges using PCIe native hotplug) added code that made the acpiphp driver completely ignore PCIe root complexes for which the kernel had been granted control of the native PCIe hotplug feature by the BIOS through _OSC. Later commit 619a5182d1f38a3d629ee48e04fa182ef9170052 "PCI hotplug: Always allow acpiphp to handle non-PCIe bridges" relaxed the constraints to allow acpiphp driver handle non-PCIe bridges under such a complex. The constraint needs to be relaxed further to allow acpiphp driver to handle PCIe ports without native PCIe hotplug capability. Some MR-IOV switch chipsets, such PLX8696, support multiple virtual PCIe switches and may migrate downstream ports among virtual switches. To migrate a downstream port from the source virtual switch to the target, the port needs to be hot-removed from the source and hot-added into the target. The pciehp driver can't be used here because there are no slots within the virtual PCIe switch. So acpiphp driver is used to support downstream port migration. A typical configuration is as below: [Root without native PCIe HP] [Upstream port of vswitch without native PCIe HP] [Downstream port of vswitch with native PCIe HP] [PCIe endpoint] Here acpiphp driver will be used to handle root ports and upstream port in the virtual switch, and pciehp driver will be used to handle downstream ports in the virtual switch.

2012-09-24PCI/ACPI: Pass acpi_pci_root to acpi_pci_drivers' add/remove interfaceTaku Izumi
This patch changes .add/.remove interfaces of acpi_pci_driver. In the current implementation acpi_handle is passed as a parameter of .add/.remove interface. However, the acpi_pci_root structure contains more useful information than just the acpi_handle. This enables us to avoid some useless lookups in each acpi_pci_driver. Note: This changes interfaces used by acpi_pci_register_driver(), an exported symbol. This patch updates all the in-kernel users, but any out-of-kernel acpi_pci_register_driver() users will need updates.

2012-09-18powerpc/eeh: Remove EEH PE for normal PCI hotplugGavin Shan
Function eeh_rmv_from_parent_pe() could be called by the path of either normal PCI hotplug, or EEH recovery. For the former case, we need purge the corresponding PE on removal of the associated PE bus. The patch tries to cover that by passing more information to function pcibios_remove_pci_devices() so that we know if the corresponding PE needs to be purged or be marked as "invalid".

Previously, the driver ignored resume unless the pciehp_force module_param was specified.

Typically, the return value desired for the failure of a function with an integer return value is a negative integer. In these cases, the return value is sometimes a negative integer and sometimes 0, due to a subsequent initialization of the return variable within the loop.

2012-06-13PCI: acpiphp: remove all functions in slot, even without ACPI _EJxAmos Kong
When we add a device with acpiphp, we enumerate all functions in the slot with pci_scan_slot(), regardless of whether they have associated ACPI methods such as _EJ0. When removing the device, we previously removed only the functions with those ACPI methods. This patch makes the remove symmetric with the add: we remove all functions in the slot, whether they have associated ACPI methods or not. With qemu-kvm and SeaBIOS, we can build a multi-function device where only function 0 has _EJ0 and _ADR (see bugzilla below). Removing and re-adding that slot (including all functions of the device) works correctly with Windows guests. This patch makes it also work in Linux guests.
