  • 8e4ceb38e   USB: prepare for changover to Runtime PM framework ... Browse Code »

    This patch (as1303) revises the USB Power Management infrastructure to
    make it compatible with the new driver-model Runtime PM framework:

    Drivers are no longer allowed to access intf->pm_usage_cnt
    directly; the PM framework manages its own usage counters.

    usb_autopm_set_interface() is eliminated, because it directly
    sets intf->pm_usage_cnt.

    usb_autopm_enable() and usb_autopm_disable() are eliminated,
    because they call usb_autopm_set_interface().

    usb_autopm_get_interface_no_resume() and
    usb_autopm_put_interface_no_suspend() are added. They
    correspond to pm_runtime_get_noresume() and
    pm_runtime_put_noidle() in the PM framework.

    The power/level attribute no longer accepts "suspend", only
    "on" and "auto". The PM framework doesn't allow devices to be
    forced into a suspended mode.

    The hub driver contains the only code that violates the new
    guidelines. It is updated to use the new interface routines instead.

  • fb34d5375   USB: remove the auto_pm flag ... Browse Code »

    This patch (as1302) removes the auto_pm flag from struct usb_device.
    The flag's only purpose was to distinguish between autosuspends and
    external suspends, but that information is now available in the
    pm_message_t argument passed to suspend methods.

    The documentation for usbmon in the kernel 2.6.31-rc7 kernel doesn't
    match what the kernel exposes in the debug fs tree. This patch fixes it.

    This patch adds an extension to the binary API so it reaches parity with
    existing text API (so-called "1u"). The extension delivers additional data,
    such as ISO descriptors and the interrupt interval.

    Move DMA-mapping.txt to Documentation/PCI/.

    DMA-mapping.txt was supposed to be moved from Documentation/ to
    Documentation/PCI/. The 00-INDEX files in those two directories
    were updated, along with a few other text files, but the file
    itself somehow escaped being moved, so move it and update more
    text files and source files with its new location.

    This patch (as1160b) adds support routines for asynchronous autosuspend
    and autoresume, with accompanying documentation updates. There
    already are several potential users of this interface, and others are
    likely to arise as autosuspend support becomes more widespread.

  • 6fae35f9c   uwb: add basic radio manager ... Browse Code »

    The UWB radio manager coordinates the use of the radio between the
    PALs that may be using it. PALs request use of the radio with
    uwb_radio_start() and the radio manager will start beaconing if its
    not already doing so. When the last PAL has called uwb_radio_stop()
    beaconing will be stopped.

    In the future, the radio manager will have a more sophisticated channel
    selection algorithm, probably following the Channel Selection Policy
    from the WiMedia Alliance when it is finalized. For now, channel 9
    (BG1, TFC1) is selected.

    The user may override the channel selected by the radio manager and may
    force the radio to stop beaconing.

    The WUSB Host Controller PAL makes use of this and there are two new
    debug PAL commands that can be used for testing.

  • 88d987d6d   usb: auerswald: remove driver (obsolete) ... Browse Code »

    This patch removes the auerswald USB driver from the linux kernel
    2.6.26.

    This driver was included into the kernel mainly to connect to the ISDN
    framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile
    and moving ISDN support, this connection was never realized, and the
    only use of this driver was for device configuration. In the age of DSL,
    the demand of ISDN support is getting very low.

    Meanwhile, with the advent of libusb, an userspace driver was done for
    the device configuration which works fine for linux and mac. (Thanks to
    the libusb developers!). The userspace driver is downloadable from the
    auerswald web site.

    So this driver is obsolete now and has to be removed. Many thanks to all
    developers which helped me to bring this driver up and working.

  • 86c57edf6   USB: use reset_resume when normal resume fails ... Browse Code »

    This patch (as1109b) makes USB-Persist more resilient to errors. With
    the current code, if a normal resume fails, it's an unrecoverable
    error. With the patch, if a normal resume fails (and if the device is
    enabled for USB-Persist) then a reset-resume is tried.

    This fixes the problem reported in Bugzilla #10977.

  • a7707adf9   usb gadget: use new serial core ... Browse Code »

    Teach "gadget serial" to use the new abstracted (and bugfixed) TTY glue,
    and remove all the orignal tangled-up code. Update the documentation
    accordingly. This is a net object code shrink and cleanup; it should
    make it a lot easier to see how the TTY glue should accomodate updates
    to the TTY layer, be bugfixed, etc.

    Notable behavior changes include: it can now support getty even when
    there's no USB connection; it fits properly into the mdev/udev world;
    and RX handling is better (throttling works, and low latency).

    Configurations with scripts setting up the /dev/ttygserial device node
    (with "experimental" major number) may want to change that to be a
    symlink pointing to the /dev/ttyGS0 file, as a migration aid; else,
    just switch entirely over to mdev/udev.

    G_PRINTER: Adds a USB printer gadget driver for use in printer firmware.

    This adds a USB printer gadget driver for use in printer firmware.
    The printer gadget channels data between the USB host and a userspace
    program driving the print engine. The user space program reads and
    writes the device file /dev/g_printer to receive or send printer data.
    It can use ioctl calls to the device file to get or set printer status.
