Driver core: fix devres_release_all() return value

2007-07-11T23:09:02+00:00

Every file should include the headers containing the prototypes for
it's global functions.

Since the GNU C compiler is now able to detect that the function 
prototype of devres_release_all() in the header and the actual function 
disagree regarding the return value, this patch also fixes this bug.

remove "struct subsystem" as it is no longer needed

2007-05-03T01:57:59+00:00

We need to work on cleaning up the relationship between kobjects, ksets and
ktypes.  The removal of 'struct subsystem' is the first step of this,
especially as it is not really needed at all.

Thanks to Kay for fixing the bugs in this patch.

driver core: don't fail attaching the device if it cannot be bound

2007-04-27T17:57:29+00:00

Don't fail bus_attach_device() if the device cannot be bound.

If dev->driver has been specified, reset it to NULL if device_bind_driver()
failed and add the device as an unbound device.  As a result,
bus_attach_device() now cannot fail, and we can remove some checking from
device_add().

Also remove an unneeded check in bus_rescan_devices_helper().

devres: device resource management

2007-02-09T22:39:36+00:00

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()

[PATCH] Driver core: change make_class_name() to take kobjects

2006-06-21T19:40:49+00:00

This is needed for a future patch for the device code to create the
proper symlinks for devices that are "class devices".

[PATCH] Driver Core: Add /sys/hypervisor when needed

2006-06-21T19:40:48+00:00

To have a home for all hypervisors, this patch creates /sys/hypervisor.
A new config option SYS_HYPERVISOR is introduced, which should to be set
by architecture dependent hypervisors (e.g. s390 or Xen).

[PATCH] drivers/base/: proper prototypes

2006-02-06T20:17:17+00:00

This patch contains the following changes:
- move prototypes to base.h
- sys.c should #include "base.h" for getting the prototype of it's
  global function system_bus_init()

Note that hidden in this patch there's a bugfix:

Caller and callee disagreed regarding the return type of
sysdev_shutdown().
