  • If a radio controller reset attempt occurs while a probe() or remove()
    is in progress it fails and is retried endlessly, potentially preventing
    the probe() or remove() from completing.

    If a reset fails, sleep for a bit before retrying the reset. This
    allows the probe()/remove() to complete.

  • Greatly enhance the MAS allocator:
    - Handle row and column reservations.
    - Permit all the available MAS to be allocated.
    - Follows the WiMedia rules on MAS selection.

    Take appropriate action when reservation conflicts are detected.
    - Correctly identify which reservation wins the conflict.
    - Protect alien BP reservations.
    - If an owned reservation loses, resize/move it.
    - Follow the backoff procedure before requesting additional MAS.

    When reservations are terminated, move the remaining reservations (if
    necessary) so they keep following the MAS allocation rules.

  • The UWB_NOTIF_BG_JOIN/UWB_NOTIF_BG_LEAVE events have been
    superceeded by the channel_changed callback in struct uwb_pal.

  • 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.

  • Use an event thread per-radio controller so processing events from one
    radio controller doesn't delay another.

    A radio controller shouldn't have information on devices seen by a
    different radio controller (they may be on different channels) so make the
    beacon cache per-radio controller.

  • ECMA-368 requires that IEs in a beacon must be sorted by element ID. Most
    hardware uses the ordering in the Set IE URC command so get the ordering
    right on the host.

    Also refactor the IE management code:
    - use uwb_ie_next() instead of uwb_ie_for_each().
    - remove unnecessary functions.
    - API is now only uwb_rc_ie_add() and uwb_rc_ie_rm().

  • Reference counting the struct uwb_rsv's is safer and easier to get right than
    the transferring ownership of the structures from the PAL to reservation
    manager.

    This fixes an oops in the debug PAL after a reservation timed out.
