This patch (as874) adds another piece to the user-visible part of the USB autosuspend interface. The new power/level sysfs attribute allows users to force the device on (with autosuspend off), force the device to sleep (with autoresume off), or return to normal automatic operation. Signed-off-by:

Add logical channel support for ATI Remote Wonder II The ATI Remote Wonder II can be configured with one of 16 unique logical channels. Allowing up to 16 remotes to be used independently within range of each other. This change adds functionality to configure the receiver and filter the input data to respond or exclude remotes configured with different logical channels. Signed-off-by:

the sierra driver does not directly use usb_kill_urb(). It uses a wrapper. This wrapper means that callbacks which are running are not killed during close, resubmitting and illicitly pushing data into the tty layer. The whole purpose of usb_kill_urb() is subverted. The wrapper must be removed. The same problem as the option driver. Signed-off-by:

This patch (as872) adds some WARN_ON()s to various error checks which are never supposed to fail. Unsettlingly, one of them has shown up in a user's log! Maybe making the warning more visible and having the call-stack information available will help pinpoint the source of the problem. Signed-off-by:

This fixes: - breaking DMA rules about buffers - usage of _global_ variables to save a single device's attributes - racy access to urb->status - smp monotonity issue with statistics - use of one buffer for many simultaneous URBs - error handling introduced - several instances of following NULL pointers - use after free - unnecessary GFP_ATOMIC - GFP_KERNEL in interrupt - various cleanups - write room granularity issue that bit cdc-acm - race in shutdown Signed-off-by:

io_edgeport is using a global variable without locking. This is _the_ classical race condition. This patch switches to atomic_t. Signed-off-by:

This patch (as870) adds a delay to ehci-hcd's bus_resume routine. Apparently there are controllers and/or BIOSes out there which need such a delay to get the ports back into their correct state. This fixes Bugzilla #8190. Signed-off-by:
-
Alan Stern authored
This patch (as867) adds an entry for the new power/autosuspend attribute in Documentation/ABI/testing, and it changes the behavior of the delay value. Now a delay of 0 means to autosuspend as soon as possible, and negative values will prevent autosuspend. Signed-off-by:

This patch (as866) adds new entry points for external USB device suspend and resume requests, as opposed to internally-generated autosuspend or autoresume. It also changes the existing remote-wakeup code paths to use the new routines, since remote wakeup is not the same as autoresume. As part of the change, it turns out to be necessary to do remote wakeup of root hubs from a workqueue. We had been using khubd, but it does autoresume rather than an external resume. Using the ksuspend_usb_wq workqueue for this purpose seemed a logical choice. Signed-off-by:

this driver has an interesting way of handling ENOMEM: complain and ignore. If you decide to live with allocation failures, you must 1. guard against URBs without corresponding buffers 2. complete allocation failures 3. always test entries for NULL before you follow the pointers This patch does so.

This patch (as865) fixes a race in the HCD removal code discovered by Milan Plzik. Arrival of an interrupt after the root hub was unregistered could cause the root-hub status timer to start up, even after it was supposed to have been shut down. The problem is fixed by moving the del_timer_sync() call to after the HCD's stop() method, at which time IRQ generation should be disabled. Cc: Milan Plzik <milan.plzik@gmail.com> Signed-off-by:

I've acquired a second device for testing and plan to make some changes in the near future to export all the device stats to sysfs (based on my proposed patch to add them to the proc file ~2007-01-30). Signed-off-by:

When the device is polled for status there is a lot of useful status information available that is ignored. This patch stores the device info array when the status is polled and adds sysfs files to the usb device to allow userspace to query it. Since the device updates its status internally once a second the poll time is changed to this, and round_jiffies_relative is used to avoid waking the cpu unnecessarily. Signed-off-by:

There is currently no path from the ATM device in /sys to the USB device's interface that the driver is using; this patch creates a "device" symlink. It is then possible to get to the cxacru ADSL statistics (http://lkml.org/lkml/2007/2/23/328): /sys/class/atm/cxacru0/device $ ls *_rate *_margin *_attenuation downstream_attenuation downstream_snr_margin upstream_rate downstream_rate upstream_attenuation upstream_snr_margin If this link is not appropriate I'd have to create device files in /sys/class/atm/cxacru0 instead - which seems less appropriate since the ADSL statistics are for the USB device not ATM (which is running over the ADSL).

compilation of the skeleton driver is currently broken. It doesn't compile. So while I am it: - fix typo - add comments to answer common questions - actually allow autosuspend in the driver struct - increase paralellism by restricting code under locks Signed-off-by:
