PCI: cpqphp: stop managing hotplug_slot->name

2008-12-05T18:55:17+00:00

commit 30ac7acd05d1449ac784de144c4b5237be25b0b4 upstream.

We no longer need to manage our version of hotplug_slot->name
since the PCI and hotplug core manage it on our behalf.

Now, we simply advise the PCI core of the name that we would
like, and let the core take care of the rest.

PCI Hotplug core: add 'name' param pci_hp_register interface

2008-12-05T18:55:16+00:00

commit 1359f2701b96abd9bb69c1273fb995a093b6409a upstream.

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.

PCI hotplug: cpqphp: fix kernel NULL pointer dereference

2008-10-25T21:32:42+00:00

commit d2174c3c07adad88dd9ba37a731e0b00b746822a upstream

The following patch fixes the regression in 2.6.27 that causes kernel
NULL pointer dereference at cpqphp driver probe time.  This patch should
be backported to the .27 stable series.

Seems to have been introduced by
f46753c5e354b857b20ab8e0fe7b2579831dc369.

The root cause of this problem seems that cpqphp driver calls
pci_hp_register() wrongly. In current implementation, cpqphp driver
passes 'ctrl->pci_dev->subordinate' as a second parameter for
pci_hp_register(). But because hotplug slots and it's hotplug controller
(exists as a pci funcion) are on the same bus, it should be
'ctrl->pci_dev->bus' instead.

PCI: introduce pci_slot

2008-06-10T21:37:03+00:00

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.

cpqphp: Use PCI_CLASS_REVISION instead of PCI_REVISION_ID for read

2007-10-12T22:03:16+00:00

While PCI_CLASS_REVISION and PCI_REVISION_ID are identical, the
code here discards the revision content and is only interested in
the class number.

PCI: Change all drivers to use pci_device->revision

2007-07-11T23:02:10+00:00

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

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

2006-10-18T18:36:12+00:00

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...
