PM: Remove sysdev suspend, resume and shutdown operations

2011-05-11T19:37:15+00:00

Since suspend, resume and shutdown operations in struct sysdev_class
and struct sysdev_driver are not used any more, remove them.  Also
drop sysdev_suspend(), sysdev_resume() and sysdev_shutdown() used
for executing those operations and modify all of their users
accordingly.  This reduces kernel code size quite a bit and reduces
its complexity.

Introduce ARCH_NO_SYSDEV_OPS config option (v2)

2011-03-23T21:16:41+00:00

Introduce Kconfig option allowing architectures where sysdev
operations used during system suspend, resume and shutdown have been
completely replaced with struct sycore_ops operations to avoid
building sysdev code that will never be used.

Make callbacks in struct sys_device and struct sysdev_driver depend
on ARCH_NO_SYSDEV_OPS to allows us to verify if all of the references
have been actually removed from the code the given architecture
depends on.

Make x86 select ARCH_NO_SYSDEV_OPS.

sysdev: Add sysdev_create/remove_files

2010-03-08T01:04:47+00:00

Allow to create/remove arrays of sysdev attributes

Just wrappers around sysfs_create/move_files

Will be used later to clean up some drivers.

sysfs: Add attribute array to sysdev classes

2010-03-08T01:04:47+00:00

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/store

2010-03-08T01:04:47+00:00

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 attributes

2008-07-22T04:55:02+00:00

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 function

2008-07-22T04:55:02+00:00

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

cpumask: add show cpu map functions

2008-04-19T17:44:59+00:00

  * 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 names

2008-01-25T04:40:40+00:00

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.
