Currently we rely on intf->dev.power.power_state.event for tracking whether intf is suspended. This is not a reliable technique because that value is owned by the PM core, not by usbcore. This patch (as718b) adds a new flag so that we can accurately tell which interfaces are suspended and which aren't. At first one might think these flags aren't needed, since interfaces will be suspended along with their devices. It turns out there are a couple of intermediate situations where that's not quite true, such as while processing a remote-wakeup request.

This patch (as717b) removes the existing recursion in hub resume code: Resuming a hub will no longer automatically resume the devices attached to the hub. At the same time, it adds one level of recursion: Suspending a USB device will automatically suspend all the device's interfaces. Failure at an intermediate stage will cause all the already-suspended interfaces to be resumed. Attempts to suspend or resume an interface by itself will do nothing, although they won't return an error. Thus the regular system-suspend and system-resume procedures should continue to work as before; only runtime PM will be affected. The patch also removes the code that tests state of the interfaces before suspending a device. It's no longer needed, since everything gets suspended together.

This patch (as716b) splits up the core suspend and resume routines into two parts each: one for handling devices and one for handling interfaces.

This patch (as714b) makes usb_generic into a usb_device_driver capable of being probed and unbound, just like other drivers. A fair amount of the work that used to get done during discovery or removal of a USB device have been moved to the probe and disconnect methods of usb_generic: creating the sysfs attributes and selecting an initial configuration. However the normal behavior should continue to be the same as before. We will now have the possibility of creating other USB device drivers, They will assist with exporting devices to remote systems (USB-over-TCPIP) or to paravirtual guest operating systems.

This patch (as732) adds a usb_device_driver structure, for representing drivers that manage an entire USB device as opposed to just an interface. Support routines like usb_register_device_driver, usb_deregister_device_driver, usb_probe_device, and usb_unbind_device are also added. Unlike an earlier version of this patch, the new code is type-safe. To accomplish this, the existing struct driver embedded in struct usb_driver had to be wrapped in an intermediate wrapper. This enables the core to tell at runtime whether a particular struct driver belongs to a device driver or to an interface driver.

This revised patch (as713b) moves a few routines among source files in usbcore. Some driver-related code in usb.c (claiming interfaces and matching IDs) is moved to driver.c, where it belongs. Also the usb_generic stuff in driver.c is moved to a new source file: generic.c. (That's the reason for revising the patch.) Although not very big now, it will get bigger in a later patch. None of the code has been changed; it has only been re-arranged. Signed-off-by: NAlan Stern <stern@rowland.harvard.edu> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This revised patch (as715b) renames usb_suspend_device to usb_port_suspend, usb_resume_device to usb_port_resume, and finish_device_resume to finish_port_resume. There was no objection to the original version of the patch so this should be okay to apply. The revision was needed only because I have re-arranged the order of the earlier patches.

This patch (as712b) is a slight revision of one submitted earlier. It fixes the usb-skeleton example driver so that it won't try to submit URBs after skel_disconnect() has returned. This could cause errors, if the driver was unbound and then a different driver was bound to the device. It also fixes a couple of small bugs in the skel_write() routine. The revised patch uses a slightly different test, suggested by Dave Brownell, for determining whether to free a transfer buffer. It's a little clearer than the earlier version.

This patch (as711b) is a revised version of an earlier submission. It modifies the usbfs code to detect when a device has been unregistered from usbfs, even if the device is still connected. Although this can't happen now, it will be able to happen after the upcoming changes to usb_generic. Nobody objected to this patch when it was submitted before, so it should be okay to apply this version. The revision is merely to take into account the changes introduced by as723, which touches the same driver.

The usbfs code doesn't provide sufficient mutual exclusion among open, release, and remove. Release vs. remove is okay because they both acquire the device lock, but open is not exclusive with either one. All three routines modify the udev->filelist linked list, so they must not run concurrently. Apparently someone gave this a minimum amount of thought in the past by explicitly acquiring the BKL at the start of the usbdev_open routine. Oddly enough, there's a comment pointing out that locking is unnecessary because chrdev_open already has acquired the BKL. But this ignores the point that the files in /proc/bus/usb/* are not char device files; they are regular files and so they don't get any special locking. Furthermore it's necessary to acquire the same lock in the release and remove routines, which the code does not do. Yet another problem arises because the same file_operations structure is accessible through both the /proc/bus/usb/* and /dev/usb/usbdev* file nodes. Even when one of them has been removed, it's still possible for userspace to open the other. So simple locking around the individual remove routines is insufficient; we need to lock the entire usb_notify_remove_device notifier chain. Rather than rely on the BKL, this patch (as723) introduces a new private mutex for the purpose. Holding the BKL while invoking a notifier chain doesn't seem like a good idea.

This patch (as737b) does a very small cleanup of core/sysfs.c by adding the configuration_string attribute file to the existing attribute group instead of treating it separately. It doesn't need this separate treatment because unlike the other device string attributes, it changes along with the active configuration. The patch also fixes a simple typo (which, oddly enough, doesn't seem to bother the compiler).

Add (dummy?) support for TIOCGSERIAL and TIOCSSERIAL ioctl calls to the USB serial driver file `ark3116.c'. This is sufficient for me to run wvdial successfully, receive my email, and do webbrowsing with firefox. On the other hand, running the cvs program to update archives seems not to work, and the traceroute command sometimes says send failed: No buffer space available Looks like a buffering problem...

This updates the PXA 25x UDC board-independent infrastructure for VBUS sensing and the D+ pullup. The original code evolved from rather bizarre support on Intel's "Lubbock" reference hardware, so that on more sensible hardware it doesn't work as well as it could/should. The change is just to teach the UDC driver how to use built-in PXA GPIO pins directly. This reduces the amount of board-specfic object code needed, and enables the use of a VBUS sensing IRQ on boards (like Gumstix) that have one. With VBUS sensing, the UDC is unclocked until a host is actually connected. Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

With the newer Samsung S3C2412 and S3C2413 SoC devices, the 48MHz USB clock has been given an individual gate into the USB OHCI and gadget blocks. This clock is called usb-bus-clock, and we need to replace the old use of the USB PLL (upll) directly with the new usb-bus-host. The S3C2410 clock driver has been updated already to provide a virtual clock which is a child of the UPLL to maintain compatibility. The S3C2412 clock driver correctly enables the PLL when either usb-bus clock is active. Signed-off-by: NBen Dooks <ben-linux@fluff.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This teaches OHCI to use the root hub status change (RHSC) IRQ, bypassing root hub timers most of the time and switching over to the "new" root hub polling scheme. It's complicated by the fact that implementations of OHCI trigger and ack that IRQ differently (the spec is vague there). Avoiding root hub timers helps mechanisms like "dynamic tick" leave the CPU in lowpower modes for longer intervals.

In de_thread we move pids from one process to another, a rather ugly case. The function transfer_pid makes it clear what we are doing, and makes the action atomic. This is useful we ever want to atomically traverse the process group and session lists, in a rcu safe manner. Even if the atomic properties this change should be a win as transfer_pid should be less code to execute than executing both attach_pid and detach_pid, and this should make de_thread slightly smaller as only a single function call needs to be emitted. The only downside is that the code might be slower to execute as the odds are against transfer_pid being in cache. Signed-off-by: NEric W.
