This patch (as1385) adds a "do_wakeup" parameter to the pci_suspend method used by PCI-based host controller drivers. ehci-hcd in particular needs to know whether or not to enable wakeup when suspending a controller. Although that information is currently available through device_may_wakeup(), when support is added for runtime suspend this will no longer be true. Signed-off-by:

This patch (as1384) moves the resume_common() routine in hcd-pci.c a little higher in the source file to avoid forward references in an upcoming patch. It also replaces the "hibernated" argument with a more general "event" argument, which will be useful when the routine is called during a runtime resume. Signed-off-by:

This patch (as1383) takes the powermac-specific code from the PCI HCD glue layer and encapsulates it in its own subroutine. Signed-off-by:

This commit cleans the g_fs gadget hopefully making it more readable. This is achieved by usage of the usb_string_ids_tab() function for batch string IDs registration as well as generalising configuration so that a single routine is used to add each configuration and bind interfaces. As an effect, the code is shorter and has fewer #ifdefs. Moreover, in some circumstances previous code #defined CONFIG_USB_FUNCTIONFS_GENERIC macro to prevent a situation where gadget with no configurations is built. This code removes the #define form source code and achieves the same effect using select in Kconfig. This patch also changes wording and names of the Kconfig options. Signed-off-by:

This patch (as1393) converts several of the single-bit fields in struct usb_hcd to atomic flags. This is for safety's sake; not all CPUs can update bitfield values atomically, and these flags are used in multiple contexts. The flag fields that are set only during registration or removal can remain as they are, since non-atomic accesses at those times will not cause any problems. (Strictly speaking, the authorized_default flag should become atomic as well. I didn't bother with it because it gets changed only via sysfs. It can be done later, if anyone wants.) Signed-off-by:

In may gadgets bind and bind like functions were in a init section as they were only run during initialisation. However, being callback functions they were referenced from structures in “normal” sections. Changing the tag from “__init” to “__ref” fixes the warnings. Signed-off-by:

Added pre_eject() and post_eject() callbacks which are called before and after removable logical unit is ejected. The first can prevent logical unit from being ejected. This commit also changes the way callbacks are passed to the function from gadget. A fsg_operations structure has been created which lists all callbacks -- this is passed to the fsg_config. This is important because it changes the way thread_exits() callback is passed. Signed-off-by:

Added a disconnect() callback to composite devices which is called by composite glue when its disconnect callback is called by gadget. Signed-off-by:

The Multifunction Composite Gadget have been cleaned up and refactored so hopefully it looks prettier and works at least as good as before changes. A Kconfig has also been fixed to make it impossible to build FunctionFS gadget with no configurations. With this patch, if RNDIS is not chosen by the user CDC is force-selected. Signed-off-by:

The ep0req_name was never used in f_mass_storage hence it may be safely removed from the code. It was a leftover from File Storage Gadget which used it for debug messages. Signed-off-by:

Use usb_string_ids_n() function to simplify string ids registeration. Signed-off-by:
-
Michal Nazarewicz authored
usb_string_ids_tab() and usb_string_ids_n() functions added to the composite framework. The first accepts an array of usb_string object and for each registeres a string id and the second registeres a given number of ids and returns the first. This may simplify string ids registration since gadgets and composite functions won't have to call usb_string_id() several times and each time check for errer status -- all this will be done with a single call.

compat_ioctl does not use the BKL, so I assume that the native function does not need it either. The open function is already protected by the driver's mutex, the BKL is probably not needed here either. Signed-off-by:

There is no gadget driver in the tree that actually implements the ioctl operation, so obviously it is not necessary to hold the BKL around the call. Signed-off-by:

BKL was not really needed, just came from earlier push downs. The only part that's a bit dodgy is the lseek function. Would need another lock or atomic access to fpos on 32bit? Better to have a libfs lseek Signed-off-by:

The usb serial driver initialization tried to use the BKL to stop driver modules from unloading, but that didn't work anyways. There was already some code to do proper try_module_get, but it was conditional on having a new probe interface. I checked all the low level drivers and they all have proper .owner = THIS_MODULE, so it's ok to always use. The other problem was the usb_serial_driver_list needing protection by a lock. This was broken anyways because unregister did not necessarily have the BKL. I extended the extending table_lock mutex to protect this case too. With these changes the BKL can be removed here.

And audit all the users. None needed the BKL. That was easy because there was only very few around. Tested with allmodconfig build on x86-64 Signed-off-by: -
Andi Kleen authored
The code this is attempting to lock against does not use the BKL, so it's not needed. Most likely this code is still broken/racy (Al Viro also thinks so), but removing the BKL should not make it worse than before. Signed-off-by:

EHCI 1.1 addendum introduced several energy efficiency extensions for EHCI USB host controllers: 1. LPM (link power management) 2. Per-port change 3. Shorter periodic frame list 4. Hardware prefetching This patch is intended to define the HW bits and debug interface for EHCI 1.1 addendum. The LPM and Per-port change patches will be sent out after this patch. Signed-off-by:
