Driver Core: add nodename callbacks

2009-06-16T04:30:25+00:00

This adds the nodename callback for struct class, struct device_type and
struct device, to allow drivers to send userspace hints on the device
name and subdirectory that should be used for it.

This removes the
	warning: format not a string literal and no format arguments
warnings in the driver core that gcc 4.3.3 complains about.

driver core: synchronize device shutdown

2009-06-16T04:30:24+00:00

A patch series to make .shutdown execute asynchronously.  Some drivers's
shutdown can take a lot of time.  The patches can help save some shutdown
time.  The patches use Arjan's async API.


This patch:

Driver Core: do not oops when driver_unregister() is called for unregistered drivers

2009-05-28T21:24:07+00:00

We also fix a problem with cleaning up properly when initializing
drivers and devices, so checks like this will work successfully.

Portions of the patch by Linus and Greg and Ingo.

driver: dont update dev_name via device_add path

2009-04-20T15:12:58+00:00

notice one system /proc/iomem some entries missed the name for pci_devices

it turns that dev->dev.kobj name is changed after device_add.

for pci code: via acpi_pci_root_driver.ops.add (aka acpi_pci_root_add)
==> pci_acpi_scan_root is used to scan pci bus/device, and at the same
time we read the resource for pci_dev in the pci_read_bases, we have
res->name = pci_name(pci_dev); pci_name is calling dev_name.

later via acpi_pci_root_driver.ops.start (aka acpi_pci_root_start) ==>
pci_bus_add_device to add all pci_dev in kobj tree.  pci_bus_add_device
will call device_add.

actually in device_add

        /* first, register with generic layer. */
        error = kobject_add(&dev->kobj, dev->kobj.parent, "%s", dev_name(dev));
        if (error)
                goto Error;

will get one new name for that kobj, old name is freed.

[Impact: fix corrupted names in /proc/iomem ]

driver core: prevent device_for_each_child from oopsing

2009-04-16T23:17:11+00:00

David Vrabel noticed that the wireless usb stack likes to call
device_for_each_chile() with an empty bus.  This used to work fine, but
now oopses.  This patch fixes the oops and makes the code behave like it
used to.

Driver core: Fix device_move() vs. dpm list ordering, v2

2009-03-24T23:38:26+00:00

dpm_list currently relies on the fact that child devices will
be registered after their parents to get a correct suspend
order. Using device_move() however destroys this assumption, as
an already registered device may be moved under a newly registered
one.

This patch adds a new argument to device_move(), allowing callers
to specify how dpm_list should be adapted.

Driver core: implement uevent suppress in kobject

2009-03-24T23:38:26+00:00

This patch implements uevent suppress in kobject and removes it
from struct device, based on the following ideas:

1,Uevent sending should be one attribute of kobject, so suppressing it
in kobject layer is more natural than in device layer. By this way,
we can do it for other objects embedded with kobject.

2,It may save several bytes for each instance of struct device.(On my
omap3(32bit ARM) based box, can save 8bytes per device object)

This patch also introduces dev_set|get_uevent_suppress() helpers to
set and query uevent_suppress attribute in case to help kobject
as private part of struct device in future.

driver core: move klist_children into private structure

2009-03-24T23:38:25+00:00

Nothing outside of the driver core should ever touch klist_children, or
knode_parent, so move them out of the public eye.

driver core: create a private portion of struct device

2009-03-24T23:38:25+00:00

This is to be used to move things out of struct device that no code
outside of the driver core should ever touch.
