PCI: introduce pci_slot

2008-06-10T21:37:03Z

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.

PCI: fix rpadlpar pci hotplug driver sysfs usage

2008-05-30T16:50:46Z

When Greg "fixed" the sysfs usage of that driver a while back, he seem to have introduced a bug where the quotes are added around the name of our specific sysfs files, thus breaking the user space tool. This fixes it. Tested DLPAR operations on a POWER6 machine successfully. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Jesse Barnes

Kobject: convert drivers/* from kobject_unregister() to kobject_put()

2008-01-25T04:40:40Z

There is no need for kobject_unregister() anymore, thanks to Kay's kobject cleanup changes, so replace all instances of it with kobject_put(). Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman

kobject: clean up rpadlpar horrid sysfs abuse

2008-01-25T04:40:24Z

rpadlpar pci hotplug driver was doing some pretty bad stuff with the sysfs files. This cleans up the logic to be sane and gets rid of the gratuitous kset that is not needed for a simple directory like this. Note, this patch is not even build tested, let alone run-time tested. Someone with access to this hardware and can test would be greatly appreciated. Cc: Kay Sievers Cc: John Rose Cc: Badari Pulavarty Cc: Kamalesh Babulal Signed-off-by: Greg Kroah-Hartman

kset: convert pci hotplug to use kset_create_and_add

2008-01-25T04:40:14Z

This also renames pci_hotplug_slots_subsys to pcis_hotplug_slots_kset catch all current users with a build error instead of a build warning which can easily be missed. Cc: Kay Sievers Cc: Kristen Carlson Accardi Signed-off-by: Greg Kroah-Hartman

kobject: remove struct kobj_type from struct kset

2008-01-25T04:40:10Z

We don't need a "default" ktype for a kset. We should set this explicitly every time for each kset. This change is needed so that we can make ksets dynamic, and cleans up one of the odd, undocumented assumption that the kset/kobject/ktype model has. This patch is based on a lot of help from Kay Sievers. Nasty bug in the block code was found by Dave Young Cc: Kay Sievers Cc: Dave Young Signed-off-by: Greg Kroah-Hartman

Drivers: clean up direct setting of the name of a kset

2007-10-12T21:51:02Z

A kset should not have its name set directly, so dynamically set the name at runtime. This is needed to remove the static array in the kobject structure which will be changed in a future patch. Signed-off-by: Greg Kroah-Hartman

PCI Hotplug: move pci_hotplug.h to include/linux/

2006-10-18T18:36:12Z

This makes it possible to build pci hotplug drivers outside of the main kernel tree, and Sam keeps telling me to move local header files to their proper places... Signed-off-by: Greg Kroah-Hartman
