Over two years ago, the Linux USB developers stated that they believed
there was no way to create a USB kernel driver that was not under the
GPL. This patch moves the USB apis to enforce that decision.
There are no known closed source USB drivers in the wild, so this patch
should cause no problems.

Turns out that a company is out there using the vendor id of 0x0000 in
the wild, so use a real vendor/product id for the root hubs.
Now that the Linux Foundation has a real vendor id, we use that, and the
first product id:
0x1d6b is the vendor id of the Linux Foundation
0x0001 is the product id for Linux 1.1 root hubs
0x0002 is the product id for Linux 2.0 root hubs
The usb.ids file has already been updated with these values.

While most isochronous endpoints have short polling intervals, the
EHCI driver won't necessarily handle larger ones correctly.
This patch switches to use a "u16" to represent those periods, not
a u8, since it can always work: the largest expressible period
is 2^15 units ... not the previous too-short limit of 128 frames
(full or low speeds) or microframes (high speed, 32 frames).
This bug is essentially theoretical, since the few ISO endpoints
I've seen which don't use one transfer per frame are high speed
ones using more than that (including high bandwidth, 24 KB/msec).

This has some bugfixes for the EHCI driver's ISO transfer scanning
logic. It was leaving ITDs and SITDs on the schedule too long, for
a few different reasons, which caused trouble.
(a) Look at all microframes for high speed transfers, not just
the ones we expect to have finished. This way transfers
ending mid-frame will complete without needing another IRQ.
This also minimizes bogus scheduling underruns (e.g. EL2NSYNC).
(b) When we encounter an ISO transfer (either speed, but this
hits mostly at full speed) that's not yet been completed,
immediately stop scanning; we've caught up to the hardware,
no matter what other indications might say.
(c) Always clean up ITDs (for high speed transfers) when the HC
is no longer running.
I'm not sure whether the last one has been observed before, but both
the others have been reported with "real world" audio and video code.

Small updates to the EHCI driver's ISO support:
- Get rid of the Kconfig option for full speed ISO. It may
not be perfect yet, but it hasn't appeared to be dangerous
and pretty much every configuration wants it.
- Instead of two places to disable an empty periodic schedule
after an ISO transfer completes, just have one.
- After the periodic schedule is disabled, we can short-circuit
the schedule scan ... it can't possibly have more work to do.
Assuming a typical config with split iso enabled, the only change
in behavior should be almost unobservable: quicker termination
of periodic scans when the schedule gets emptied.

This patch exports two statistics to userspace:
/sys/bus/usb/device/.../power/connected_duration
/sys/bus/usb/device/.../power/active_duration
connected_duration is the total time (in msec) that the device has
been connected. active_duration is the total time the device has not
been suspended. With these two statistics, tools like PowerTOP can
calculate the percentage time that a device is active, i.e. not
suspended or auto-suspended.
Users can also use the active_duration to check if a device is actually
autosuspended. Currently, they can set power/level to auto and
power/autosuspend to a positive timeout, but there's no way to know from
userspace if a device was actually autosuspended without looking at the
dmesg output. These statistics will be useful in creating an automated
userspace script to test autosuspend for USB devices.

This adds a workaround for an issue reported with ISO transfers
on some EHCI controllers, most recently with VIA KT800 and PS3
EHCI silicon.
The issue is that the silicon doesn't necessarily seem to be done
using ISO DMA descriptors (itd, sitd) when it marks them inactive.
(One theory is that the ill-defined mechanism where hardware caches
periodic transfer descriptors isn't invalidating their state...)
With such silicon, quick re-use of those descriptors makes trouble.
Waiting until the next frame seems to be a sufficient workaround.
This patch ensures that the relevant descriptors aren't available
for immediate re-use. It does so by not recycling them until after
issuing the completion callback which would reuse them by enqueueing
an URB and thus (re)allocating ISO DMA descriptors.

Make sure the generic resume function does not submit the URBs if we're
coming back from autosuspend. On autoresume, we know that the open
function will be called next, which will attempt to submit the URBs. If
we submit them in the resume function, the open will fail.
This works for:
- autosuspend
- suspending with the tty open or closed
- hibernate with the tty closed
A hibernate (or a suspend that causes the USB subsystem to lose power)
has issues. If you have the tty open when you hibernate, a new tty will
be created when the device re-enumerates during resume.

The usb serial method set_termios() is called for the first time from
open() method in order to set up the termios structure with the default
device's settings, ignoring the current settings. Once it's initialized,
the next set_termios() calls will update the device with the
tty->termios settings.
Currently USB serial console code calls the driver open() method without
a tty and after that will allocate a fake tty and termios so the command
line arguments can be applied to the device
(console=ttyUSB0,115200,...). This makes the driver overwrite the
termios with the default settings and not applying the command line
options.
This patch changes usb_console_setup() to allocate the fake tty and
termios before the open() method is called.
Tested successfully with a pl2303

When a usb serial adapter is used as console, the usb serial console
driver bumps the open_count on the port struct used but doesn't attach
a real tty to it (only a fake one temporaly). If this port is opened later
using the regular character device interface, the open method won't
initialize the port, which is the expected, and will receive a brand new
tty struct created by tty layer, which will be stored in port->tty.
When the last close is issued, open_count won't be 0 because of the
console usage and the port->tty will still contain the old tty value. This
is the last ttyUSB<n> close so the allocated tty will be freed by the
tty layer. The usb_serial and usb_serial_port are still in use by the
console, so port_free() won't be called (serial_close() ->
usb_serial_put() -> destroy_serial() -> port_free()), so the scheduled
work (port->work, usb_serial_port_work()) will still run. And
usb_serial_port_work() does:
(...)
tty = port->tty;
if (!tty)
return;
tty_wakeup(tty);
which causes (manually copied):

needs to be re-enabled every time you get a new kernel. Additionally a

Currently our users have to follow the instructions we provide at

is too complicated to compile their own kernel module.
We are aware that you can specify one additional device using the

sector size alignment requirements, so I upped their alignments in the

Cleaning out all the incorrect 'no change made' checks for termios
settings showed up a problem with the PL2303. The hardware here seems to
lose sync and bits if you tell it to make no changes. This shows up with
a real world application.
To fix this the driver check for meaningful hardware changes is restored
but doing the tests correctly and as a tty layer function so it doesn't
get duplicated wrongly everywhere if other drivers turn out to need it.

The OHCI IRQ handler has an optimisation that avoids reading some
chip registers when the controller reports that the interrupt was
triggered *only* because completed requests were written into the
controller's "done list" and handed to the host.
This mechanism can't be used on some controllers. Among others, it
fails for the SA1111 and the AMCC 440EP PowerPC processor.
This patch removes the optimisation and makes the code clearer.

Correct hanging while disconnecting the USB device cable. Prevent a race
between vbus and UDP interrupts. This bug was tracked on at91sam9260ek
boards.
A usb resume interrupt was firing after the vbus interrupt : the IP was
then already stoped and not able to deal with it (no more clock). A simple
interrupt disabling is ok as the "end of bus reset" irq is non maskable and
ok to resume the USB device IP.

When a device cannot handle the smallest previously limited transfer
size (64 blocks) without stalling, limit the device to the amount of
packets that fit in a platform native page.
The lowest possible limit is PAGE_CACHE_SIZE, so if the device is ever

can convince the device firmware folks to fix the issue.

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.

Also, along the way:
- Change usb_unlink_urb to usb_kill_urb. Apparently there's no need
to use usb_unlink_urb whatsoever in this driver, and the old use of
usb_kill_urb was outright racy (it unlinked and immediately freed).

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.

converted many files to use the scatter gather helpers without ensuring
that the necessary headerfile <linux/scatterlist> is included. This
happened to work for ia64, powerpc, sparc64 and x86 because they
happened to drag in that file via their <asm/dma-mapping.h>.
On most of the others this probably broke.
Instead of increasing the header file spider web I choose to include
<linux/scatterlist.h> directly into the affectes files.

Most of these fixes were already submitted for old kernel versions, and were
approved, but for some reason they never made it into the releases.
Because this is a consolidation of a couple old missed patches, it touches both
Kconfigs and documentation texts.

* Convert files to UTF-8.
* Also correct some people's names
(one example is Eißfeldt, which was found in a source file.
Given that the author used an ß at all in a source file
indicates that the real name has in fact a 'ß' and not an 'ss',
which is commonly used as a substitute for 'ß' when limited to
7bit.)

The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.
The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

Introduce freezer-friendly wrappers around wait_event_interruptible() and
wait_event_interruptible_timeout(), originally defined in <linux/wait.h>, to
be used in freezable kernel threads. Make some of the freezable kernel
threads use them.
This is necessary for the freezer to stop sending signals to kernel threads,
which is implemented in the next patch.

Various console drivers are able to resize the screen via the con_resize()
hook. This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and
VT_RESIZEX ioctl's. One particular utility, SVGATextMode, expects that
con_resize() of the VGA console will always return success even if the
resulting screen is not compatible with the hardware. However, this
particular behavior of the VGA console, as reported in Kernel Bugzilla Bug
7513, can cause undefined behavior if the user starts with a console size
larger than 80x25.
To work around this problem, add an extra parameter to con_resize(). This
parameter is ignored by drivers except for vgacon. If this parameter is
non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl
and vgacon will always return success. If this parameter is zero, vgacon will
return -EINVAL if the requested size is not compatible with the hardware. The
latter is the more correct behavior.
With this change, SVGATextMode should still work correctly while in-kernel and
stty resize calls can expect correct behavior from vgacon.

This patch (as1002) fixes a small race which can occur when a driver
expects usbcore to reschedule an autosuspend request. If the request
arrives too late, it won't be rescheduled. The patch adds an extra
argument to autosuspend_check(), indicating that a reschedule is
needed no matter how much time has elapsed.
It also tries to avoid letting asynchronous changes to the value of
jiffies cause a delay to become negative, by caching a local copy of
the current time.

Keep track of the device status (as returned by the GET_STATUS

well as SET_FEATURE/CLEAR_FEATURE (for remote wakeup)
Implement the wakeup() op, which refuses to do anything if the
DEVICE_REMOTE_WAKEUP feature wasn't set by the host. Now this

This patch (as997) fixes a bug in the USB serial core. The core needs
to pay attention to drivers' requirements regarding the number and
type of endpoints a device has.
At the same time, the patch changes the NUM_DONT_CARE constant (which
is stored in a single-byte field) from -1 to a safer, unsigned value.
It also improves the kerneldoc for several fields in the
usb_serial_driver structure.
Finally, the patch replaces a list_for_each() with list_for_each_entry().

System suspends and hibernation are supposed to be as transparent as
possible. By this reasoning, if a USB device is already autosuspended
before the system sleep begins then it should remain autosuspended
after the system wakes up.
This patch (as1001) adds a skip_sys_resume flag to the usb_device
structure and uses it to avoid waking up devices which were suspended
when a system sleep began.

This patch (as999) fixes a problem that sometimes shows up when host
controller driver modules are loaded in the wrong order. If ehci-hcd
happens to initialize an EHCI controller while the companion OHCI or
UHCI controller is in the middle of a port reset, the reset can fail
and the companion may get very confused. The patch adds an
rw-semaphore and uses it to keep EHCI initialization and port resets
mutually exclusive.

Attached is a very small patch (several comment lines) and a one-line
coded change) that allows for USB storage devices that are larger than
2TB.
At the company where I work we need such support, and one of my
co-workers, Jane Liu, pointed out that SCSI low-layer drivers need to
specify what size CDBs they accept. After looking through the code it
became obvious that the current USB Storage code accepted the default of
12-byte CDBs, so I changed it to accept 16-byte CDBs. This allows our
device to work.

This is a dual speed controller (connects at high or full speed).
The driver supports up to 7 control, bulk, interrupt and isochronous
endpoints with some constraints. Bulk, interrupt and isochronous
transfers are driven by DMA.

Add OHCI big endian frame_no quirk. The frame_no value stored in the
HCCA is a 16 bit field at a specific offset, but since not all CPUs can
do 16-bit memory accesses it's used as a 32 bit field. And that's why
big-endian OHCI must shift 16 bits ... unless the spec is not followed.
Currently there's one MPC52xx platform that doesn't need the shift. This
patch adds a new "big endian frame_no" quirk to control that at runtime.
