[CLASS DEVICE]: add attribute_group creation

2006-05-07T00:55:11+00:00

Extend the support of attribute groups in class_device's to allow
groups to be created as part of the registration process. This allows
network device's to avoid race between registration and creating
groups.

Note that unlike attributes that are a property of the class object,
the groups are a property of the class_device object. This is done
because there are different types of network devices (wireless for
example).

[PATCH] driver core: fix unnecessary NULL check in drivers/base/class.c

2006-04-14T18:41:24+00:00

This patch tries to fix an issue in drivers/base/class.c, please
review and apply if correct.

Patch Description:
  "parent_class" is checked for NULL already, so removed the unnecessary
  check.

[PATCH] driver core: replace "hotplug" by "uevent"

2006-01-05T00:18:08+00:00

Leave the overloaded "hotplug" word to susbsystems which are handling
real devices. The driver core does not "plug" anything, it just exports
the state to userspace and generates events.

[PATCH] fix missing includes

2005-10-31T01:37:32+00:00

I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

[PATCH] Driver Core: add the ability for class_device structures to be nested

2005-10-28T16:52:51+00:00

This patch allows struct class_device to be nested, so that another
struct class_device can be the parent of a new one, instead of only
having the struct class be the parent.  This will allow us to
(hopefully) fix up the input and video class subsystem mess.

But please people, don't go crazy and start making huge trees of class
devices, you should only need 2 levels deep to get everything to work
(remember to use a class_interface to get notification of a new class
device being added to the system.)

Oh, this also allows us to have the possibility of potentially, someday,
moving /sys/block into /sys/class.  The main hindrance is that pesky
/dev numberspace issue...

[PATCH] add sysfs attr to re-emit device hotplug event

2005-10-28T16:52:51+00:00

A "coldplug + udevstart" can be simple like this:
  for i in /sys/block/*/*/uevent; do echo 1 > $i; done
  for i in /sys/class/*/*/uevent; do echo 1 > $i; done
  for i in /sys/bus/*/devices/*/uevent; do echo 1 > $i; done

[PATCH] Driver core: pass interface to class interface methods

2005-10-28T16:52:51+00:00

Driver core: pass interface to class intreface methods

Pass interface as argument to add() and remove() class interface
methods. This way a subsystem can implement generic add/remove
handlers and then call interface-specific ones.

[PATCH] Driver core: send hotplug event before adding class interfaces

2005-10-28T16:52:50+00:00

Move call to kobject_hotplug() above code that adds interfaces
to a class device, otherwise children's hotplug events may reach
userspace first.

[PATCH] fix class symlinks in sysfs

2005-09-22T14:58:24+00:00

The class symlinks in sysfs don't properly handle changing device names.

To demonstrate, rename your network device from eth0 to eth1. Your
pci (or usb, or whatever) device will still have a 'net:eth0' link,
except now it points to /sys/class/net/eth1.

The attached patch makes sure the class symlink name changes when
the class device name changes. It isn't 100% correct, it should be
using sysfs_rename_link. Unfortunately, sysfs_rename_link doesn't exist.
