acpiphp is writing hot plug parameters to the PCI host bridge PCI config space. This patch removes the incorrect operation.

On systems where the optional _PS3 ACPI object is not implemented acpiphp fails to power off the slot. This is happening because the current code does not attempt to remove power using the _EJ0 ACPI object. This patch restores the _EJ0 evaluation attempt which was apparently inadvertently removed from the power-off sequence when the _EJ0 evaluation code was relocated from power_off_slot() to acpiphp_eject_slot().

Contrary to PCI bridge hot-add, we need to follow the sequence below for PCI bridge hot-removal.

Dock bridges generally do not implement _SUN, yet show up as ejectable slots. If you have more than one ejectable slot that does not implement SUN, with the current code you will get duplicate slot numbers.

o hotplug slots add When the hot-added PCI device is p2p bridge, acpiphp calls find_p2p_bridge() to add hotplug slots. o hotplug slots remove When the hot-removing PCI device is p2p bridge, acpiphp calls cleanup_p2p_bridge() to remove hotplug slots. o notify handler exchange When the p2p bridge is added, acpiphp changes the notify hanlder. If no bridge device is inserted into the hotpluggable PCI slot, acpiphp installs the notify handler for function. After the p2p bridge hot-add, acpiphp has to install the notify handler for bridge. Because, the role of the handlers are not same. The hot-remove case is ditto. Signed-off-by: NMUNEDA Takahiro <muneda.takahiro@jp.fujitsu.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

shpchprm_acpi.c and pciehprm_acpi.c are nearly identical. In addition, there are functions in both these files that are also in acpiphp_glue.c. This patch will remove duplicate functions from shpchp, pciehp, and acpiphp and move this functionality to pci_hotplug, as it is not hardware specific. Get rid of shpchprm* and pciehprm* files since they are no longer needed. shpchprm_nonacpi.c and pciehprm_nonacpi.c are identical, as well as shpchprm_legacy.c and can be replaced with a macro.

Current ACPIPHP driver scans only slots under the top level PCI-to-PCI bridge. So hotplug PCI slots under the nested PCI-to-PCI bridge would not be detected. For example, if the system has the ACPI namespace like below, hotplug slots woule not be detected. Device (PCI0) { /* Root bridge */ Name (_HID, "PNP0A03") Device (P2PA) { /* PCI-to-PCI bridge */ Name (_ADR, ...) Device (P2PB) { /* PCI-to-PCI bridge */ Name (_ADR, ...) Device (S0F0) { /* hotplug slot */ Name (_ADR, ...) Name (_SUN, ...) Method (_EJ0, ...) { ... } } ... Device (S0F7) { /* hotplug slot */ Name (_ADR, ...) Name (_SUN, ...) Method (_EJ0, ...) { ... } } Device (S1F0) { /* hotplug slot */ Name (_ADR, ...) Name (_SUN, ...) Method (_EJ0, ...) { ... } } ... } } } This patch fixes this issue.

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. This patch incorporates feedback provided by many. Signed-off-by: NKristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>
