Alan Stern 3b4d7f7916 [PATCH] USB: Support unbinding of the usb_generic driver
This patch (as556) adds support for unbinding the usb_generic "driver".
That driver only binds to USB devices, as opposed to interfaces, and it
does nothing much besides marking which struct device's go with an
overall USB device plus providing suspend/resume methods.  Now that
users can unbind drivers at will using the sysfs "unbind" attribute, we
need a rational way of dealing with USB devices that are no longer under
full control of the USB stack.  The patch handles this by unconfiguring
the device, thereby removing all the interfaces and their associated
drivers and children.

This patch (as555) modifies the already-awkward

whole point of the routine is that the caller wants to acquire some

Alan Stern bf193d3cd2 [PATCH] USB: Disconnect children when unbinding the hub driver
This patch (as554) makes the hub driver disconnect any child USB devices
when it is unbound from a hub.  Normally this will never happen, but
there are a few oddball ways to unbind the hub driver while leaving the
children intact.  For example, the new "unbind" sysfs attribute can be
used for this purpose.

Given that unbinding hubs with children is now safe, the patch also
removes the code that prevented people from doing so using usbfs.

Alan Stern b375a0495f [PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernel
29 July 2005, Cambridge, MA:

This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK
flag from the Linux kernel.  Mr. Stern explained, "This flag is a relic
from an earlier, less-well-designed system.  For over a year it hasn't
been used for anything other than printing warning messages."

An anonymous spokesman for the Linux kernel development community
commented, "This is exactly the sort of thing we see happening all the
time.  As the kernel evolves, support for old techniques and old code can
be jettisoned and replaced by newer, better approaches.  Proprietary
operating systems do not have the freedom or flexibility to change so
quickly."

Mr. Stern, a staff member at Harvard University's Rowland Institute who
works on Linux only as a hobby, noted that the patch (labelled as548) did
not update two files, keyspan.c and option.c, in the USB drivers' "serial"
subdirectory.  "Those files need more extensive changes," he remarked.
"They examine the status field of several URBs at times when they're not
supposed to.  That will need to be fixed before the URB_ASYNC_UNLINK flag
is removed."

Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all
of Linux's USB drivers, did not respond to our inquiries or return our
calls.  His only comment was "Applied, thanks."

Kay Sievers fbf82fd2e1 [PATCH] USB: real nodes instead of usbfs
This patch introduces a /sys/class/usb_device/ class
where every connected usb-device will show up:

  tree /sys/class/usb_device/
  /sys/class/usb_device/
  |-- usb1.1
  |   |-- dev
  |   `-- device -> ../../../devices/pci0000:00/0000:00:1d.0/usb1
  |-- usb2.1
  |   |-- dev
  |   `-- device -> ../../../devices/pci0000:00/0000:00:1d.1/usb2
  ...

The presence of the "dev" file lets udev create real device nodes.
  kay@pim:~/src/linux-2.6> tree /dev/bus/usb/
  /dev/bus/usb/
  |-- 1
  |   `-- 1
  |-- 2
  |   `-- 1
  ...

udev rule:
  SUBSYSTEM="usb_device", PROGRAM="/sbin/usb_device %k", NAME="%c"
  (echo $1 | /bin/sed 's/usb\([0-9]*\)\.\([0-9]*\)/bus\/usb\/\1\/\2/')

This makes libusb pick up the real nodes instead of the mounted usbfs:
  export USB_DEVFS_PATH=/dev/bus/usb

Background:
  All this makes it possible to manage usb devices with udev instead of
  the devfs solution. We are currently working on a pam_console/resmgr
  replacement driven by udev and a pam-helper. It applies ACL's to device
  nodes, which is required for modern desktop functionalty like
  "Fast User Switching" or multiple local login support.

New patch with its own major. I've succesfully disabled usbfs and use real
nodes only on my box. With: "export USB_DEVFS_PATH=/dev/bus/usb" libusb picks
up the udev managed nodes instead of reading usbfs files.

This makes udev to provide symlinks for libusb to pick up:
  SUBSYSTEM="usb_device", PROGRAM="/sbin/usbdevice %k", SYMLINK="%c"

/sbin/usbdevice:
  #!/bin/sh
  echo $1 | /bin/sed 's/usbdev\([0-9]*\)\.\([0-9]*\)/bus\/usb\/\1\/\2/'

interface shouldn't be fatal either -- I think; you may disagree about

Alan Stern d5926ae7a8 [PATCH] usbcore support for root-hub IRQ instead of polling
This is a revised version of an earlier patch to add support to usbcore
for driving root hubs by interrupts rather than polling.

There's a temporary flag added to struct usb_hcd, marking devices whose
drivers are aware of the new mechanism.  By default that flag doesn't get
set so drivers will continue to see the same polling behavior as before.
This way we can convert the HCDs one by one to use interrupt-based event
reporting, and the temporary flag can be removed when they're all done.

Also included is a small change to the hcd_disable_endpoint routine.
Although endpoints normally shouldn't be disabled while a controller is
suspended, it's legal to do so when the controller's driver is being
rmmod'ed.

Lastly the patch adds a new callback, .hub_irq_enable, for use by HCDs
where the root hub's port-change interrupts are level-triggered rather
than edge-triggered.  The callback is invoked each time khubd has finished
processing a root hub, to let the HCD know that the interrupt can safely
be re-enabled.

   frozen_process(process)	Process is frozen now

2. Remove all references to PF_FREEZE and PF_FROZEN from all
   kernel sources except sched.h

3. Fix numerous locations where try_to_freeze is manually done by a driver

4. Remove the argument that is no longer necessary from two function calls.

5. Some whitespace cleanup

6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
   cleared before setting PF_FROZEN, recalc_sigpending does not check
   PF_FROZEN).

This patch does not address the problem of freeze_processes() violating the rule
that a task may only modify its own flags by setting PF_FREEZE. This is not clean
in an SMP environment. freeze(process) is therefore not SMP safe!

Patrick Mochel 273971bade [PATCH] usb: klist_node_attached() fix
The original code looks like this:

        /* if interface was already added, bind now; else let
         * the future device_add() bind it, bypassing probe()
         */
        if (!list_empty (&dev->bus_list))
                device_bind_driver(dev);

IOW, it's checking to see if the device is attached to the bus or not
and binding the driver if it is. It's checking the device's bus list,
which will only appear empty when the device has been initialized, but
not added. It depends way too much on the driver model internals, but it
seems to be the only way to do the weird crap they want to do with
interfaces.

When I converted it to use klists, I accidentally inverted the logic,
which led to bad things happening. This patch returns the check to its
orginal value.

Dmitry Torokhov 8d790d7408 [PATCH] make driver's name be const char *
Driver core:
  change driver's, bus's, class's and platform device's names
  to be const char * so one can use
            const char *drv_name = "asdfg";
  when initializing structures.
  Also kill couple of whitespaces.

Alan Stern 8835f66573 [PATCH] USB: USB API documentation modification
In response to complaints about excessive latency in the uhci-hcd driver
I'm planning to convert it to a top-half/bottom-half design.  It turns out
that to do this, the USB API has to be modified slightly since the driver
will not be able to meet one of the guarantees in the current API.  This
patch changes some kerneldoc, specifying the weaker guarantee.

I am sorry that the last patch about 32 bit compat ioctl on
64 bit kernel actually breaks the usbdevfs. That is on the current
BK tree. I am retarded. 

Here is the patch to fix it. Tested with USB hard disk and webcam
in both 32bit compatible mode and native 64bit mode.

Again, sorry about that.

David Brownell a81e7ecca3 [PATCH] USB: revert "fix" to usb_set_interface()
This reverts a recent change to usb_set_interface().  The change worked
around a quirk in certain devices, but doing this in usbcore creates
needless regressions for other devices.  More appropriate fixes won't
put such handling in usbcore.

Basically it's tricky to do a full software reset of USB device state, since
the devices don't all act the same.  This adds a note to the kerneldoc for
the usb_reset_configuration() call to highlight the quirk this was working
around:  endpoint data toggles not being reset.

David Brownell 9a5d3e98dd [PATCH] USB: hcd suspend uses pm_message_t
This patch includes minor "sparse -Wbitwise" updates for the PCI based
HCDs.  Almost all of them involve just changing the second parameter of the
suspend() method to a pm_message_t ...  the others relate to how the EHCI
code walks in-memory data structures.  (There's a minor bug fixed there too
...  affecting the big-endian sysfs async schedule dump.)

David Brownell 27d72e8572 [PATCH] usb suspend updates (interface suspend)
This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t".  This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:

    - <linux/usb.h> and usbcore, signature change

    - Some drivers only changed the signature, net effect this just
      shuts up "sparse -Wbitwise":
	* hid-core
	* stir4200

    - Two network drivers did that, and also grew slightly more
      featureful suspend code ... they now properly shut down
      their activities.  (As should stir4200...)
	* pegasus
	* usbnet

Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.

David Brownell c6053ecffb [PATCH] usb resume fixes
This has a variety of updates to the shared suspend/resume code for
PCI based USB host controllers.

    - Cope with pm_message_t replacing the target system state.
      This is actually a loss of functionality; PCI D1 and D2
      states will no longer be used, and it's no longer knowable
      that D3cold is on the way so power will be lost.

    - Most importantly, some of the resume paths are reworked and
      cleaned up.  They're now an exact mirror of suspend paths,
      and more care is taken to ensure the hardware is reactivated
      before the hardware re-enables interrupts.

Plus comment and diagnostic cleanups; there are some nasty cases here 
especially combined with swsusp, now they're somewhat commented.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
