2008-10-22PCI: SGI Hotplug: stop managing bss_hotplug_slot->nameAlex Chiang
We no longer need to manage our version of hotplug_slot->name since the PCI and hotplug core manage it on our behalf. Update the sn_hp_slot_private_alloc() interface to fill in the correct name for us, as that function already has all the parameters needed to determine the name.

2008-10-22PCI Hotplug core: add 'name' param pci_hp_register interfaceAlex Chiang
Update pci_hp_register() to take a const char *name parameter. The motivation for this is to clean up the individual hotplug drivers so that each one does not have to manage its own name. The PCI core should be the place where we manage the name. We update the interface and all callsites first, in a "no functional change" manner, and clean up the drivers later.

2008-10-11ACPI: Change acpi_evaluate_integer to support 64-bit on 32-bit kernelsMatthew Wilcox
As of version 2.0, ACPI can return 64-bit integers. The current acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms. Change the argument to take a pointer to an acpi_integer so we support 64-bit integers on all platforms. lenb: replaced use of "acpi_integer" with "unsigned long long" lenb: fixed bug in acpi_thermal_trips_update() Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2008-06-10PCI: ACPI PCI slot detection driverAlex Chiang
Detect all physical PCI slots as described by ACPI, and create entries in /sys/bus/pci/slots/. Not all physical slots are hotpluggable, and the acpiphp module does not detect them. Now we know the physical PCI geography of our system, without caring about hotplug.

2008-06-10PCI: introduce pci_slotAlex Chiang
Currently, /sys/bus/pci/slots/ only exposes hotplug attributes when a hotplug driver is loaded, but PCI slots have attributes such as address, speed, width, etc. that are not related to hotplug at all. Introduce pci_slot as the primary data structure and kobject model. Hotplug attributes described in hotplug_slot become a secondary structure associated with the pci_slot. This patch only creates the infrastructure that allows the separation of PCI slot attributes and hotplug attributes. In this patch, the PCI hotplug core remains the only user of this infrastructure, and thus, /sys/bus/pci/slots/ will still only become populated when a hotplug driver is loaded. A later patch in this series will add a second user of this new infrastructure and demonstrate splitting the task of exposing pci_slot attributes from hotplug_slot attributes. - Make pci_slot the primary sysfs entity. hotplug_slot becomes a subsidiary structure. o pci_create_slot() creates and registers a slot with the PCI core o pci_slot_add_hotplug() gives it hotplug capability - Change the prototype of pci_hp_register() to take the bus and slot number (on parent bus) as parameters. - Remove all the ->get_address methods since this functionality is now handled by pci_slot directly.

2007-02-02Altix: Add ACPI SSDT PCI device support (hotplug)John Keller
Support for dynamic loading and unloading of ACPI SSDT tables upon slot hotplugs and unplugs. On SN platforms, we now represent every populated root bus slot with a single ACPI SSDT table containing info for every device and PPB attached to the slot. These SSDTs are generated by the prom at initial boot and hotplug time. The info in these SSDT tables is used by the SN kernel IO "fixup" code (which is called at boot and hotplug time). On hotplugs (i.e. enable_slot()), if running with an ACPI capable prom, attempt to obtain a new ACPI SSDT table for the slot being hotplugged. If successful, add the table to the ACPI namespace (acpi_load_table()) and then walk the new devices and add them to the ACPI infrastructure (acpi_bus_add()). On hot unplugs (i.e. disable_slot()), if running with an ACPI capable prom, attempt to remove the SSDT table associated with the slot from the ACPI namespace (acpi_unload_table_id()) and infastructure (acpi_bus_trim()). From: John Keller <jpk@sgi.com> A bug was fixed where the sgi hotplug driver was removing the slot's SSDT table from the ACPI namespace a bit too early in disable_slot(). Also, we now call acpi_bus_start() subsequent to acpi_bus_add().
