* driver-core: implement 'sysdev' functionality for regular devices and busesKay Sievers2011-12-141-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | All sysdev classes and sysdev devices will converted to regular devices and buses to properly hook userspace into the event processing. There is no interesting difference between a 'sysdev' and 'device' which would justify to roll an entire own subsystem with different userspace export semantics. Userspace relies on events and generic sysfs subsystem infrastructure from sysdev devices, which are currently not properly available. Every converted sysdev class will create a regular device with the class name in /sys/devices/system and all registered devices will becom a children of theses devices. For compatibility reasons, the sysdev class-wide attributes are created at this parent device. (Do not copy that logic for anything new, subsystem- wide properties belong to the subsystem, not to some fake parent device created in /sys/devices.) Every sysdev driver is implemented as a simple subsystem interface now, and no longer called a driver. After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel.

* SYSFS: Allow boot time switching between deprecated and modern sysfs layoutAndi Kleen2010-10-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have some systems which need legacy sysfs due to old tools that are making assumptions that a directory can never be a symlink to another directory, and it's a big hazzle to compile separate kernels for them. This patch turns CONFIG_SYSFS_DEPRECATED into a run time option that can be switched on/off the kernel command line. This way the same binary can be used in both cases with just a option on the command line. The old CONFIG_SYSFS_DEPRECATED_V2 option is still there to set the default. I kept the weird name to not break existing config files. Also the compat code can be still completely disabled by undefining CONFIG_SYSFS_DEPRECATED_SWITCH -- just the optimizer takes care of this now instead of lots of ifdefs. This makes the code look nicer. v2: This is an updated version on top of Kay's patch to only handle the block devices. I tested it on my old systems and that seems to work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Constify struct sysfs_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <re.emese@gmail.com> Acked-by: David Teigland <teigland@redhat.com> Acked-by: Matt Domsch <Matt_Domsch@dell.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Acked-by: Hans J.

| | | | | | | | | | | | | | | | | | | | 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.

* Driver core: Add support for compatibility classesJean Delvare2009-09-151-0/+87
| | | | | | | | | | | | | | | | | | | | | When turning class devices into bus devices, we may need to temporarily add links in sysfs so that user-space applications are not confused. This is done by adding the following API: * Functions to register and unregister compatibility classes. These appear in sysfs at the same location as regular classes, but instead of class devices, they contain links to bus devices. * Functions to create and delete such links. Additionally, the caller can optionally pass a target device to which a "device" link should point (typically that would be the device's parent), to fully emulate the original class device. The i2c subsystem will be the first user of this API, as i2c adapters are being converted from class devices to bus devices.

* driver-core: use klist for class device list and implement iteratorTejun Heo2008-10-091-33/+103
| | | | | | | | | | | | | | | | | | | | | | Iterating over entries using callback usually isn't too fun especially when the entry being iterated over can't be manipulated freely. This patch converts class->p->class_devices to klist and implements class device iterator so that the users can freely build their own control structure. The users are also free to call back into class code without worrying about locking. class_for_each_device() and class_find_device() are converted to use the new iterators, so their users don't have to worry about locking anymore either. Note: This depends on klist-dont-iterate-over-deleted-entries patch because class_intf->add/remove_dev() depends on proper synchronization with device removal.

* sysfs: add /sys/dev/{char,block} to lookup sysfs path by major:minorDan Williams2008-07-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Why?: There are occasions where userspace would like to access sysfs attributes for a device but it may not know how sysfs has named the device or the path. For example what is the sysfs path for /dev/disk/by-id/ata-ST3160827AS_5MT004CK? With this change a call to stat(2) returns the major:minor then userspace can see that /sys/dev/block/8:32 links to /sys/block/sdc. What are the alternatives?: 1/ Add an ioctl to return the path: Doable, but sysfs is meant to reduce the need to proliferate ioctl interfaces into the kernel, so this seems counter productive. 2/ Use udev to create these symlinks: Also doable, but it adds a udev dependency to utilities that might be running in a limited environment like an initramfs. 3/ Do a full-tree search of sysfs.

* Revert "Driver core: remove class_device_*_bin_file"Greg Kroah-Hartman2007-10-311-0/+18
| | | | | | | | | | | This reverts commit fcd239d3d5575e5cc63aab5c33cf6dc66904f6d6. I messed up, ia64 still uses these files in the current tree, and now can not build the pci code, which all ia64 boxes seem to require :) This fixes that mistake. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Driver core: remove class_device_*_bin_fileGreg Kroah-Hartman2007-10-311-18/+0
| | | | | | | | | | | | These functions are not used by anyone, so remove them from the tree. The class_device code will be removed soon anyway, so no future users will ever be possible. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Driver core: rename ktype_classGreg Kroah-Hartman2007-10-121-5/+5
| | | | | | | | | | | This makes it a bit more sane when trying to figure out how to clean up the ktype mess. Based on a larger patch from Kay Sievers Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* driver core: remove subsystem_init()Greg Kroah-Hartman2007-10-121-1/+1
| | | | | | | There is only one user of it, and it is only a wrapper for kset_init(). Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Driver core: remove subsys_get()Greg Kroah-Hartman2007-10-121-1/+1
| | | | | | | | There are no more subsystems, it's a kset now so remove the function and the only two users, which are in the driver core. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Driver core: remove subsys_put()Greg Kroah-Hartman2007-10-121-1/+1
| | | | | | | | There are no more subsystems, it's a kset now so remove the function and the only two users, which are in the driver core. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Driver core: remove subsys_set_ksetGreg Kroah-Hartman2007-10-121-1/+1
| | | | | | | | | This macro is only used by the driver core and is held over from when we had subsystems. It is not needed anymore. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
