| | | | | | | | | | | | | | | | | | | | | | | | | | This converts all instances of bus_id in the sparc core kernel to use either dev_set_name(), or dev_name() depending on the need.

| * HP iLO driverDavid Altobelli2008-07-214-0/+971
| | | | | | | | | | | | | | | | | | | | | | | | | | A driver for the HP iLO/iLO2 management processor, which allows userspace programs to query the management processor. Programs can open a channel to the device (/dev/hpilo/dXccbN), and use this to send/receive queries. The O_EXCL open flag is used to indicate that a particular channel cannot be shared between processes. This driver will replace various packages HP has shipped, including hprsm and hp-ilo.

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

| * sysdev: Pass the attribute to the low level sysdev show/store functionAndi Kleen2008-07-2124-112/+239
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | driver core: Suppress sysfs warnings for device_rename(). Renaming network devices to an already existing name is not something we want sysfs to print a scary warning for, since the callers can deal with this correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first paragraph of this document implies that user space developers shouldn't use sysfs at all, but then it goes on to describe rules that developers should follow when accessing sysfs. Not only is this somewhat self-contradictory, it has been shown to discourage developers from using established sysfs interfaces. A note of caution is more appropriate than a blanket "sysfs will never be stable" assertion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | debugfs_remove_recursive() will remove a dentry and all its children. Drivers can use this to zap their whole debugfs tree so that they don't need to keep track of every single debugfs dentry they created.

| * always enable FW_LOADER unless EMBEDDED=yAdrian Bunk2008-07-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | James Bottomley recently discovered that we have {request,release}_firmware() dummies for the case of the actual functions not being available and has a fix for the bug that was actually causing build errors for built-in users with CONFIG_FW_LOADER=m. But now missing selects on FW_LOADER are no longer visible at compile-time at all and can become runtime problems. FW_LOADER is infrastructure with relatively small codesize we can safely enable for everyone, and only for people who really need small kernels (and can be expected to know what they are doing) it matters being able to disable it. This patch therefore always sets FW_LOADER=y and allows users only to disable it with EMBEDDED=y. As a bonus, we can then get rid of all "select FW_LOADER" plus the due to it required "depends on HOTPLUG" which removes some complexity from our Kconfig files.

| * sysdev: fix debugging statements in registration code.Ben Dooks2008-07-211-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The systdev_class_register() and sysdev_register() functions have pr_debug() statements which are enabled when the user selects the driver core debug. Both of these routines do not produce the correct output, as they make assumptions about data which has not been initialised. In sysdev_class_register() the code uses the kobject_name(&cls->kset.kobj) at the start of the function, but this is not setup until later in the same call. Change this to use cls->name which is passed in from the caller. The sysdev_register() function tries to get the name of the sysdev by kobject_name(&sysdev->kobj), but that isn't setup until later in the same function so change this message to use the name of the sysdev's class and add another message once the name is initialised.

| * UIO: add generic UIO platform driverUwe Kleine-König2008-07-213-0/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a generic UIO platform driver. It eliminates the need for a dedicated kernel module for simple platform devices. Users only need to implement their irq handler in platform code and fill a struct uio_info there. This helps avoiding code duplication as UIO platform drivers often share a lot of common code.

| * UIO: Add write function to allow irq maskingHans J. Koch2008-07-213-1/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes it is necessary to enable/disable the interrupt of a UIO device from the userspace part of the driver. With this patch, the UIO kernel driver can implement an "irqcontrol()" function that does this. Userspace can write an s32 value to /dev/uioX (usually 0 or 1 to turn the irq off or on). The UIO core will then call the driver's irqcontrol function. Signed-off-by: Hans J.

| | | | | | | | | | | | | | | | | | | | | | These functions are only needed if CONFIG_PROC_FS is enabled, so save the space when it is not. This also makes it easier for a patch later in this series to work properly if CONFIG_PROC_FS is not enabled.

| * Driver Core: add ability for class_find_device to start in middle of listGreg Kroah-Hartman2008-07-218-19/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mirrors the functionality that driver_find_device has as well. We add a start variable, and all callers of the function are fixed up at the same time. The block layer will be using this new functionality in a follow-on patch.
