* sysdev: Add sysdev_create/remove_filesAndi Kleen2010-03-07
| | | | | | | | | | | | Allow to create/remove arrays of sysdev attributes Just wrappers around sysfs_create/move_files Will be used later to clean up some drivers. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* sysfs: Add attribute array to sysdev classesAndi Kleen2010-03-07
| | | | | | | | | | | | | | | | | Add a attribute array that is automatically registered and unregistered to struct sysdev_class. This is similar to what struct class has. A lot of drivers add list of attributes, so it's better to do this easily in the common sysdev layer. This adds a new field to struct sysdev_class. I audited the whole tree and there are no dynamically allocated sysdev classes, so this is fully compatible.

* sysdev: Pass attribute in sysdev_class attributes show/storeAndi Kleen2010-03-07
| | | | | | | | | | | | | | | | | | | | | | | Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. Similar to sysdev_attributes and normal attributes. This is a tree-wide sweep, converting everything in one go. No functional changes in this patch other than passing the new argument everywhere. Tested on x86, the non x86 parts are uncompiled.

* sysdev: Add utility functions for simple int/ulong variable sysdev attributesAndi Kleen2008-07-22
| | | | | | | | | | | | | This adds a new sysdev_ext_attribute that stores a pointer to the variable it manages and some utility functions/macro to easily use them. Previously all users wrote custom macros to generate show/store functions for each variable, with this it is possible to avoid that in many cases.

* sysdev: Pass the attribute to the low level sysdev show/store functionAndi Kleen2008-07-22
| | | | | | | | | | | | | | | | | | | | | | This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections. Runtime tested: x86-32, x86-64 Compiled only: ia64, powerpc Not compile tested/only grep converted: sh, arm, avr32 Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* cpumask: add show cpu map functionsMike Travis2008-04-19
| | | | | | | | | | | | | | | | | * Add cpu_sysdev_class functions to display the following maps with cpulist_scnprintf(). cpu_online_map cpu_present_map cpu_possible_map * Small change to include/linux/sysdev.h to allow the attribute name and label to be different (to avoid collision with the "attr_online" entry for bringing cpus on- and off-line.)

* Driver core: change sysdev classes to use dynamic kobject namesKay Sievers2008-01-24
| | | | | | | | | | All kobjects require a dynamically allocated name now. We no longer need to keep track if the name is statically assigned, we can just unconditionally free() all kobject names on cleanup.

* sysfs: kill unnecessary attribute->ownerTejun Heo2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

* [POWERPC] Introduce _SYSDEV_ATTROlof Johansson2007-02-06

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
