2007-03-09driver core: export device_renameJohannes Berg
In wireless we'd like to allow renaming of the phy devices we surface in sysfs. The base wireless code, however, can be built modular and thus we need device_rename exported. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-03-09Driver core: add device symlink back to sysfsGreg Kroah-Hartman
This moves the device symlink back to sysfs even if CONFIG_SYSFS_DEPRECATED is enabled as too many userspace programs (well, HAL), still rely on this link to be present. I will rework the ability for sysfs to change layouts like this in the future, but for now, this patch should fix people's network connections.

2007-03-09devres: release resources on device_del()Tejun Heo
Some platform devices are driven without driver attached, so managed resources can be acquired without driver attached. Make sure such resources are released by calling devres_release_all() in device_del(). Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-02-23Driver core: fix error by cleanup up symlinks properlyJames Simmons
When a device fails to register the class symlinks where not cleaned up. This left a symlink in the /sys/class/"device"/ directory that pointed to no where. This caused the sysfs_follow_link Oops I reported earlier. This patch cleanups up the symlink. Please apply. Thank you.

Several people have reported failures in dynamic major device number handling due to the recent changes in there to avoid handing out the local/experimental majors.

2007-02-09devres: device resource managementTejun Heo
Implement device resource management, in short, devres. A device driver can allocate arbirary size of devres data which is associated with a release function. On driver detach, release function is invoked on the devres data, then, devres data is freed. devreses are typed by associated release functions. Some devreses are better represented by single instance of the type while others need multiple instances sharing the same release function. Both usages are supported. devreses can be grouped using devres group such that a device driver can easily release acquired resources halfway through initialization or selectively release resources (e.g. resources for port 1 out of 4 ports). This patch adds devres core including documentation and the following managed interfaces. * alloc/free : devm_kzalloc(), devm_kzfree() * IO region : devm_request_region(), devm_release_region() * IRQ : devm_request_irq(), devm_free_irq() * DMA : dmam_alloc_coherent(), dmam_free_coherent(), dmam_declare_coherent_memory(), dmam_pool_create(), dmam_pool_destroy() * PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed() * iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(), devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(), pcim_iomap(), pcim_iounmap() Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-02-07Driver core: add device_type to struct deviceKay Sievers
This allows us to add type specific attributes, uevent vars and release funtions. A subsystem can carry different types of devices like the "block" subsys has disks and partitions. Both types create a different set of attributes, but belong to the same subsystem. This corresponds to the low level objects: kobject -> device (object/device data) kobj_type -> device_type (type of object/device we are embedded in) kset -> class/bus (list of objects/devices of a subsystem) Signed-off-by: Kay Sievers <kay.sievers@novell.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Don't stop on the first ->probe error that is not -ENODEV/-ENXIO.

2007-02-07driver core: Allow device_move(dev, NULL).Cornelia Huck
If we allow NULL as the new parent in device_move(), we need to make sure that the device is placed into the same place as it would if it was newly registered: - Consider the device virtual tree. In order to be able to reuse code, setup_parent() has been tweaked a bit. - kobject_move() can fall back to the kset's kobject. - sysfs_move_dir() uses the sysfs root dir as fallback.

2006-12-07[PATCH] add numa node information to struct deviceChristoph Hellwig
For node-aware skb allocations we need information about the node in struct net_device or struct device. Davem suggested to put it into struct device which this patch does. In particular: - struct device gets a new int numa_node member if CONFIG_NUMA is set - there are two new helpers, dev_to_node and set_dev_node to transparently deal with the non-numa case - for pci devices the node-info is set to the value we get from pcibus_to_node. Note that for some architectures pcibus_to_node doesn't work yet at the time we call it currently. This is harmless and will just mean skb allocations aren't node-local on this architectures until the implementation of pcibus_to_node on these architectures have been updated (There are patches for x86 and x86_64 floating around) [akpm@osdl.org: cleanup] Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: Christoph Lameter <clameter@engr.sgi.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-12-01Driver core: platform_driver_probe(), can save codespaceDavid Brownell
This defines a new platform_driver_probe() method allowing the driver's probe() method, and its support code+data, to safely live in __init sections for typical system configurations. Many system-on-chip processors could benefit from this API, to the tune of recovering hundreds to thousands of bytes per driver. That's memory which is currently wasted holding code which can never be called after system startup, yet can not be removed. It can't be removed because of the linkage requirement that pointers to init section code (like, ideally, probe support) must not live in other sections (like driver method tables) after those pointers would be invalid.

2006-12-01cpu topology: consider sysfs_create_group return valueHeiko Carstens
Take return value of sysfs_create_group() into account. That function got called in case of CPU_ONLINE notification. Since callbacks are not allowed to fail on CPU_ONLINE notification do the sysfs group creation on CPU_UP_PREPARE notification. Also remember if creation succeeded in a bitmask. So it's possible to know whether it's legal to call sysfs_remove_group or not. In addition some other minor stuff: - since CPU_UP_PREPARE might fail add CPU_UP_CANCELED handling as well. - use hotcpu_notifier instead of register_hotcpu_notifier. - #ifdef code that isn't needed in the !CONFIG_HOTPLUG_CPU case.
