endpoint pseudo-devices from being deleted and recreated when a call

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

Alan Stern [Wed, 8 Aug 2007 15:48:02 +0000]
USB: make HCDs responsible for managing endpoint queues

This patch (as954) implements a suggestion of David Brownell's.  Now
the host controller drivers are responsible for linking and unlinking
URBs to/from their endpoint queues.  This eliminates the possiblity of
strange situations where usbcore thinks an URB is linked but the HCD
thinks it isn't.  It also means HCDs no longer have to check for URBs
being dequeued before they were fully enqueued.

In addition to the core changes, this requires changing every host
controller driver and the root-hub URB handler.  For the most part the
required changes are fairly small; drivers have to call
usb_hcd_link_urb_to_ep() in their urb_enqueue method,
usb_hcd_check_unlink_urb() in their urb_dequeue method, and
usb_hcd_unlink_urb_from_ep() before giving URBs back.  A few HCDs make
matters more complicated by the way they split up the flow of control.

In addition some method interfaces get changed.  The endpoint argument
for urb_enqueue is now redundant so it is removed.  The unlink status
is required by usb_hcd_check_unlink_urb(), so it has been added to
urb_dequeue.

usb: introduce usb_authorize/deauthorize()

These USB API functions will do the full authorization/deauthorization
to be used for a device. When authorized we effectively allow a
configuration to be set. Reverse that when deauthorized.

Effectively this means that we have to clean all the configuration
descriptors on deauthorize and reload them when we authorized. We could
do without throwing them out for wired devices, but for wireless, we can
read them only after authenticating, and thus, when authorizing an
authenticated device we would need to read them. So to simplify, always
release them on deauthorize(), re-read them on authorize().

Also fix leak reported by Ragner Magalhaes; in usb_deauthorize_device(),
bNumConfigurations was being set to zero before the for loop, and thus
the different raw descriptors where never being freed.

12 years agousb: split usb_new_device for clarity and refactoring

usb: split usb_new_device for clarity and refactoring

This patch takes hub.c:usb_new_device() and splits it in three parts:

- The actual actions of adding a new device (quirk detection,
  announcement and autoresume tracking)

- Actual discovery and probing of the configuration and interfaces
  (split into __usb_configure_device())

- Configuration of the On-the-go parameters (split into
  __usb_configure_device_otg()).

The fundamental reasons for doing this split are clarity (smaller
functions are easier to maintain) and to allow part of the code to be
reused when authorizing devices to connect.

When a device is authorized connection, we need to run through the
hoops we didn't run when it was connected but not authorized, which is
basically parsing the configurations and probing
them. usb_configure_device() will do that for us.

usb: add the concept of default authorization to USB hosts

This introduces /sys/bus/devices/usb*/authorized_default; it dictates
what is going to be the default authorization state for devices
connected to the host. User space can set that using the sysfs file.

We hook to the root hub instead of to the device controller as it is
quite easy to get to it in sysfs from the device structure (device
5-4.3 is usb5) vs. backtracking to the controller device.

By default it is set to be 'authorized' (!0) for normal, wired USB
devices and 'unauthorized' (0) for Wireless USB devices.

As suggested by Adrian Bunk, make authorized_default static

USB: gadget: gadget_is_{dualspeed,otg} predicates and cleanup

This adds two small inlines to the gadget stack, which will
often evaluate to compile-time constants.  That can help
shrink object code and remove #ifdeffery.

 - gadget_is_dualspeed(), currently always a compile-time
   constant (depending on which controller is selected).

 - gadget_is_otg(), usually a compile time "false", but this
   is a runtime test if the platform enables OTG (since it's
   reasonable to populate boards with different USB sockets).

It also updates two peripheral controller drivers to use these:

 - fsl_usb2_udc, mostly OTG-related bugfixes:  non-OTG devices
   must follow the rules about drawing VBUS power, and OTG ones
   need to reject invalid SET_FEATURE requests.

 - omap_udc, just scrubbing a bit of #ifdeffery.

And also gadgetfs, which lost some #ifdefs and moved to a more
standard handling of DEBUG and VERBOSE_DEBUG.

The main benefits come from patches which will follow.

routines are added for easily checking an URB's direction.  They
replace calls to usb_pipein in the DMA-mapping parts of hcd.c.

For non-control endpoints, the direction is determined directly from
the endpoint descriptor.  However control endpoints are
bi-directional; for them the direction is determined from the
bRequestType byte and the wLength value in the setup packet.

USB: OHCI handles more ZFMicro quirks

The ZF Micro OHCI controller exhibits unexpected behavior that seems to be
related to high load.  Under certain conditions, the controller will
complete a TD, remove it from the endpoint's queue, and fail to add it to
the donelist. This causes the endpoint to appear to stop responding. Worse,
if the device is removed while in that state, OHCI will hang while waiting
for the orphaned TD to complete.  The situation is not recoverable without
rebooting.

This fix enhances the scope of the existing OHCI_QUIRK_ZFMICRO flag:

 1. A watchdog routine periodically scans the OHCI structures to check
    for orphaned TDs. In these cases the TD is taken back from the
    controller and completed normally.

 2. If a device is removed while the endpoint is hung but before the
    watchdog catches the situation, any outstanding TDs are taken back
    from the controller in the 'sanitize' phase.

The ohci-hcd driver used to print "INTR_SF lossage" in this situation;
this changes it to the universally accurate "ED unlink timeout".  Other
instances of this message presumably have different root causes.

Both this Compaq quirk and a NEC quirk are now properly compiled out for
non-PCI builds of this driver.

usblp: Implement the ENOSPC convention

This patch implements a mode when a printer returns ENOSPC when it runs
out of paper. The default remains the same as before. An application which
wishes to use this function has to enable it explicitly with an ioctl
LPABORT.

This is done on a request by our (Fedora) CUPS guy, Tim Waugh. The API is
similar enough to the lp0's one that CUPS works with both (but see below),
but it's has some differences.

Most importantly, the abort mode is persistent in case of lp0: once tunelp
was run your cat fill blow up until you reboot or run tunelp again. For
usblp, I made it so the abort mode is only in effect as long as device
is open. This way you can mix and match CUPS and cat(1) freely and nothing
bad happens even if you run out of paper. It is also safer in the face
of any unexpected crashes.

It has to be noted that mixing LPABORT and O_NONBLOCK is not advised.
It probably does not do what you want: instead of returning -ENOSPC
it will always return -EAGAIN (because it would otherwise block while
waiting for the paper). Applications which use O_NONBLOCK should continue
to use LPGETSTATUS like before.

Finally, CUPS actually requires patching to take full advantage of this.
It has several components; those which invoke LPABORT work, but some of
them need the ioctl added. This is completely compatible, you can mix
old CUPS and new kernels or vice versa.

USB: Remove unneeded pointer intf from speedtch_upload_firmware()

This trivial patch removes the unneeded pointer intf returned from
usb_ifnum_to_if(), which is never used. The check for NULL can be simply done
by if (!usb_ifnum_to_if(usb_dev, 2)).

[POWERPC] Add legacy serial support for OPB with flattened device tree

Currently find_legacy_serial_ports() can find no serial ports on the
OPB with flattened device tree.  Thus no legacy boot console can be
initialized.  Just the early udbg console works, which is initialized
with udbg_init_44x_as1 on the UART's physical address specified in
kernel config.  This happens because we look for ns16750 serial
devices only and expect opb node to have a device type property.  This
patch makes it look for ns16550-compatible devices and use
of_device_is_compatible() for opb in case device type is not
specified.

12 years ago[POWERPC] Use 1TB segments
Paul Mackerras [Thu, 11 Oct 2007 10:37:10 +0000]
[POWERPC] Use 1TB segments

This makes the kernel use 1TB segments for all kernel mappings and for
user addresses of 1TB and above, on machines which support them
(currently POWER5+, POWER6 and PA6T).

We detect that the machine supports 1TB segments by looking at the
ibm,processor-segment-sizes property in the device tree.

We don't currently use 1TB segments for user addresses < 1T, since
that would effectively prevent 32-bit processes from using huge pages
unless we also had a way to revert to using 256MB segments.  That
would be possible but would involve extra complications (such as
keeping track of which segment size was used when HPTEs were inserted)
and is not addressed here.

Parts of this patch were originally written by Ben Herrenschmidt.
