2006-01-06[PATCH] pcmcia: merge suspend into device modelDominik Brodowski
Merge the suspend and resume methods for 16-bit PCMCIA cards into the device model -- for both runtime power management and suspend to ram/disk. Bugfix in ds.c by Richard Purdie Signed-Off-By: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

Move the suspend and resume methods out of the event handler, and into special functions.

2006-01-04[PATCH] net: swich device attribute creation to default attrsKay Sievers
Recent udev versions don't longer cover bad sysfs timing with built-in logic. Explicit rules are required to do that. For net devices, the following is needed: ACTION=="add", SUBSYSTEM=="net", WAIT_FOR_SYSFS="address" to handle access to net device properties from an event handler without races. This patch changes the main net attributes to be created by the driver core, which is done _before_ the event is sent out and will not require the stat() loop of the WAIT_FOR_SYSFS key.

2006-01-04[PATCH] Input: add modalias supportRusty Russell
Here's the patch for modalias support for input classes. It uses comma-separated numbers, and doesn't describe all the potential keys (no module currently cares, and that would make the strings huge). The changes to input.h are to move the definitions needed by file2alias outside __KERNEL__. I chose not to move those definitions to mod_devicetable.h, because there are so many that it might break compile of something else in the kernel. The rest is fairly straightforward.

2006-01-04[PATCH] ide: MODALIAS support for autoloading of ide-cd, ide-disk, ...Kay Sievers
IDE: MODALIAS support for autoloading of ide-cd, ide-disk, ... Add MODULE_ALIAS to IDE midlayer modules: ide-disk, ide-cd, ide-floppy and ide-tape, to autoload these modules depending on the probed media type of the IDE device. It is used by udev and replaces the former agent shell script of the hotplug package, which was required to lookup the media type in the proc filesystem. Using proc was racy, cause the media file is created after the hotplug event is sent out. The module autoloading does not take any effect, until something like the following udev rule is configured: SUBSYSTEM=="ide", ACTION=="add", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe $env{MODALIAS}" The module ide-scsi will not be autoloaded, cause it requires manual configuration. It can't be, and never was supported for automatic setup in the hotplug package. Adding a MODULE_ALIAS to ide-scsi for all supported media types, would just lead to a default blacklist entry anyway. $ modinfo ide-disk filename: /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko description: ATA DISK Driver alias: ide:*m-disk* license: GPL ... $ modprobe -vn ide:m-disk insmod /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko $ cat /sys/bus/ide/devices/0.0/modalias ide:m-disk It also adds attributes to the IDE device: $ tree /sys/bus/ide/devices/0.0/ /sys/bus/ide/devices/0.0/ |-- bus -> ../../../../../../../bus/ide |-- drivename |-- media |-- modalias |-- power | |-- state | `-- wakeup `-- uevent $ cat /sys/bus/ide/devices/0.0/{modalias,drivename,media} ide:m-disk hda disk Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-01-04[PATCH] Allow overlapping resources for platform devicesKumar Gala
There are cases in which a device's memory mapped registers overlap with another device's memory mapped registers. On several PowerPC devices this occurs for the MDIO bus, whose registers tended to overlap with one of the ethernet controllers. By switching from request_resource to insert_resource we can register the MDIO bus as a proper platform device and not hack around how we handle its memory mapped registers.

2006-01-04[PATCH] klist: Fix broken kref counting in find functionsFrank Pavlic
The klist reference counting in the find functions that use klist_iter_init_node is broken. If the function (for example driver_find_device) is called with a NULL start object then everything is fine, the first call to next_device()/klist_next increases the ref-count of the first node on the list and does nothing for the start object which is NULL. If they are called with a valid start object then klist_next will decrement the ref-count for the start object but nobody has incremented it. Logical place to fix this would be klist_iter_init_node because the function puts a reference of the object into the klist_iter struct.

2006-01-04[PATCH] Hold the device's parent's lock during probe and removeAlan Stern
This patch (as604) makes the driver core hold a device's parent's lock as well as the device's lock during calls to the probe and remove methods in a driver. This facility is needed by USB device drivers, owing to the peculiar way USB devices work: A device provides multiple interfaces, and drivers are bound to interfaces rather than to devices; Nevertheless a reset, reset-configuration, suspend, or resume affects the entire device and requires the caller to hold the lock for the device, not just a lock for one of the interfaces. Since a USB driver's probe method is always called with the interface lock held, the locking order rules (always lock parent before child) prevent these methods from acquiring the device lock. The solution provided here is to call all probe and remove methods, for all devices (not just USB), with the parent lock already acquired. Although currently only the USB subsystem requires these changes, people have mentioned in prior discussion that the overhead of acquiring an extra semaphore in all the prove/remove sequences is not overly large. Up to now, the USB core has been using its own set of private semaphores. A followup patch will remove them, relying entirely on the device semaphores provided by the driver core. The code paths affected by this patch are: device_add and device_del: The USB core already holds the parent lock, so no actual change is needed. driver_register and driver_unregister: The driver core will now lock both the parent and the device before probing or removing. driver_bind and driver_unbind (in sysfs): These routines will now lock both the parent and the device before binding or unbinding. bus_rescan_devices: The helper routine will lock the parent before probing a device. I have not tested this patch for conflicts with other subsystems. As far as I can see, the only possibility of conflict would lie in the bus_rescan_devices pathway, and it seems pretty remote. Nevertheless, it would be good for this to get a lot of testing in -mm. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-01-04[PATCH] merge kobject_uevent and kobject_hotplugKay Sievers
The distinction between hotplug and uevent does not make sense these days, netlink events are the default. udev depends entirely on netlink uevents. Only during early boot and in initramfs, /sbin/hotplug is needed. So merge the two functions and provide only one interface without all the options. The netlink layer got a nice generic interface with named slots recently, which is probably a better facility to plug events for subsystem specific events. Also the new poll() interface to /proc/mounts is a nicer way to notify about changes than sending events through the core. The uevents should only be used for driver core related requests to userspace now. Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-04[PATCH] remove mount/umount uevents from superblock handlingKay Sievers

2006-01-04[PATCH] add uevent_helper control in /sys/kernel/Kay Sievers
This deprecates the /proc/sys/kernel/hotplug file, as all this stuff should be in /sys some day, right? :) In /sys/kernel/ we have now uevent_seqnum and uevent_helper. The seqnum is no longer used by udev, as the version for this kernel depends on netlink which events will never get out-of-order. Recent udev versions disable the /sbin/hotplug helper with an init script, cause it leads to OOM on big boxes by running hundreds of shells in parallel. It should be done now by: echo "" > /sys/kernel/uevent_helper (Note that "-n" does not work, cause neighter proc nor sysfs support truncate().)

These days we use udev to manage all kernel events. /proc/sys/kernel/hotplug will usually be disabled by an init-script. pnpnbios is not integrated with the driver core and should stay away from the now disabled /sbin/hotplug.
