drivers/base: base.h implicitly depends on <linux/notifier.h> This file is currently relying on <linux/module.h> sneaking it in through the implicit include paths from device.h. Once that is cleaned up, this will happen: In file included from drivers/base/init.c:12: drivers/base/base.h:34: error: field ‘bus_notifier’ has incomplete type make[3]: *** [drivers/base/init.o] Error 1 Fix it up in advance, so the cleanup can continue.

[PATCH] drivers/base - fix sparse warnings There are a number of sparse warnings from the latest sparse snapshot being generated from the drivers/base build. The main culprits are due to the initialisation functions not being declared in a header file. Also, the firmware.c file should include <linux/device.h> to get the prototype of firmware_register() and firmware_unregister(). This patch moves the init function declerations from the init.c file to the base.h, and ensures it is included in all the relevant c sources. It also adds <linux/device.h> to the included headers for firmware.c. The patch does not solve all the sparse errors generated, but reduces the count significantly. drivers/base/core.c:161:1: warning: symbol 'devices_subsys' was not declared.

driver core: remove fields from struct bus_type struct bus_type is static everywhere in the kernel. This moves the kobject in the structure out of it, and a bunch of other private only to the driver core fields are now moved to a private structure. This lets us dynamically create the backing kobject properly and gives us the chance to be able to document to users exactly how to use the struct bus_type as there are no fields they can improperly access.

driver-core: implement 'sysdev' functionality for regular devices and buses 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.

Driver core: add new device to bus's list before probing This patch (as1271) affects when new devices get linked into their bus's list of devices. Currently this happens after probing, and it doesn't happen at all if probing fails. Clearly this is wrong, because at that point quite a few symbolic links have already been created in sysfs. We are committed to adding the device, so it should be linked into the bus's list regardless. In addition, this needs to happen before the uevent announcing the new device gets issued. Otherwise user programs might try to access the device before it has been added to the bus. To fix both these problems, the patch moves the call to klist_add_tail() forward from bus_attach_device() to bus_add_device(). Since bus_attach_device() now does nothing but probe for drivers, it has been renamed to bus_probe_device(). And lastly, the kerneldoc is updated.

drivercore: Add driver probe deferral mechanism Allow drivers to report at probe time that they cannot get all the resources required by the device, and should be retried at a later time. This should completely solve the problem of getting devices initialized in the right order. Right now this is mostly handled by mucking about with initcall ordering which is a complete hack, and doesn't even remotely handle the case where device drivers are in modules. This approach completely sidesteps the issues by allowing driver registration to occur in any order, and any driver can request to be retried after a few more other drivers get probed. v4: - Integrate Manjunath's addition of a separate workqueue - Change -EAGAIN to -EPROBE_DEFER for drivers to trigger deferral - Update comment blocks to reflect how the code really works v3: - Hold off workqueue scheduling until late_initcall so that the bulk of driver probes are complete before we start retrying deferred devices. - Tested with simple use cases. Still needs more testing though. Using it to get rid of the gpio early_initcall madness, or to replace the ASoC internal probe deferral code would be ideal. v2: - added locking so it should no longer be utterly broken in that regard - remove device from deferred list at device_del time. - Still completely untested with any real use case, but has been boot tested.

driver core: check bus->match without holding device lock This patch moves bus->match out from driver_probe_device and does not hold device lock to check the match between a device and a driver. The idea has been verified by the commit 6cd495860901, which leads to a faster boot. But the commit 6cd495860901 has the following drawbacks: 1),only does the quick check in the path of __driver_attach->driver_probe_device, not in other paths; 2),for a matched device and driver, check the same match twice. It is a waste of cpu ,especially for some drivers with long device id table (eg. usb-storage driver). This patch adds a helper of driver_match_device to check the match in all paths, and testes the match only once.

driver-core: implement 'sysdev' functionality for regular devices and buses 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.

Driver Core: devtmpfs - kernel-maintained tmpfs-based /dev Devtmpfs lets the kernel create a tmpfs instance called devtmpfs very early at kernel initialization, before any driver-core device is registered. Every device with a major/minor will provide a device node in devtmpfs. Devtmpfs can be changed and altered by userspace at any time, and in any way needed - just like today's udev-mounted tmpfs. Unmodified udev versions will run just fine on top of it, and will recognize an already existing kernel-created device node and use it. The default node permissions are root:root 0600. Proper permissions and user/group ownership, meaningful symlinks, all other policy still needs to be applied by userspace. If a node is created by devtmps, devtmpfs will remove the device node when the device goes away. If the device node was created by userspace, or the devtmpfs created node was replaced by userspace, it will no longer be removed by devtmpfs. If it is requested to auto-mount it, it makes init=/bin/sh work without any further userspace support. /dev will be fully populated and dynamic, and always reflect the current device state of the kernel. With the commonly used dynamic device numbers, it solves the problem where static devices nodes may point to the wrong devices. It is intended to make the initial bootup logic simpler and more robust, by de-coupling the creation of the inital environment, to reliably run userspace processes, from a complex userspace bootstrap logic to provide a working /dev.
