USB: uevent environment key fix

2007-11-28T21:58:35+00:00

This patch (as1010) was written by both Kay Sievers and me.  It solves
the problem of duplicated keys in USB uevent structures by refactoring
the uevent subroutines, taking advantage of the way the hotplug core
calls uevent handlers for the device's bus and for the device's type.
Keys needed for both USB-device and USB-interface events are added in
usb_uevent(), which is the bus handler.  Keys appropriate only for
USB-device or USB-interface events are added in usb_dev_uevent() or
usb_if_uevent() respectively, the type handlers.

In addition, unnecessary tests for NULL pointers are removed as are
duplicated debugging log statements.

USB: keep track of whether interface sysfs files exist

2007-11-28T21:58:35+00:00

This patch (as1009) solves the problem of multiple registrations for
USB sysfs files in a more satisfying way than the existing code.  It
simply adds a flag to keep track of whether or not the files have been
created; that way the files can be created or removed as needed.

x86 gart: rename CONFIG_IOMMU to CONFIG_GART_IOMMU

2007-10-29T23:22:22+00:00

This patch renames the IOMMU config option to GART_IOMMU because in fact it
means the GART and not general support for an IOMMU on x86.

USB: fix interface sysfs file-creation bug

2007-10-25T19:18:44+00:00

This patch (as1005) fixes a rather subtle problem.  When
usb_set_configuration() registers the interfaces and their files in
sysfs, it doesn't expect those files to exist already.  But when an
interface is registered, its driver may call usb_set_interface() and
thereby cause the sysfs files to be created.  The result is an error
when usb_set_configuration() goes on to create those same files again.

The (not-so-great) solution is to have usb_set_configuration() remove
any existing files before creating them.

[PATCH] Fix breakage after SG cleanups

converted many files to use the scatter gather helpers without ensuring
that the necessary headerfile  is included.  This
happened to work for ia64, powerpc, sparc64 and x86 because they
happened to drag in that file via their .

On most of the others this probably broke.

Instead of increasing the header file spider web I choose to include
 directly into the affectes files.

USB: break apart flush_endpoint and disable_endpoint

2007-10-12T21:55:26+00:00

This patch (as988) breaks usb_hcd_endpoint_disable() apart into two
routines.  The first, usb_hcd_flush_endpoint() does the -ESHUTDOWN
unlinking of all URBs in the endpoint's queue and waits for them to
complete.  The second, usb_hcd_disable_endpoint() -- renamed for
better grammatical style -- merely calls the HCD's endpoint_disable
method.  The changeover is easy because the routine currently has only
one caller.

This separation of function will be exploited in the following patch:
When a device is suspended, the core will be able to cancel all
outstanding URBs for that device while leaving the HCD's
endpoint-related data structures intact for later.

As an added benefit, HCDs no longer need to check for existing URBs in
their endpoint_disable methods.  It is now guaranteed that there will
be none.

USB: don't touch sysfs stuff when altsetting is unchanged

2007-10-12T21:55:10+00:00

This patch (as955) prevents the interface-related sysfs files and
endpoint pseudo-devices from being deleted and recreated when a call
to usb_set_interface() specifies the current altsetting.  Since the
altsetting doesn't get changed, there's no need to do anything.

Furthermore, avoiding changes to the endpoint devices will be
necessary in the future.  This code is called from usb_reset_device(),
which gets invoked for reset-resume processing, but upcoming changes
to the PM and driver cores will make it impossible to register devices
while a suspend/resume transition is in progress.  Since we don't need
to re-register those endpoint devices anyhow, it's best to skip the
whole thing.
