* uwb: improved MAS allocator and reservation conflict handlingStefano Panella2008-12-122-1/+26
| | | | | | | | | | | | | | | | | | | 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.

* uwb: add basic radio managerDavid Vrabel2008-11-191-0/+2
| | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: David Vrabel <david.vrabel@csr.com>
* uwb: don't unbind the radio controller driver when resettingDavid Vrabel2008-11-071-0/+2
| | | | | | | | Use pre_reset and post_reset methods to avoid unbinding the radio controller driver after a uwb_rc_reset_all() call. This avoids a deadlock in uwb_rc_rm() when waiting for the uwb event thread to stop. Signed-off-by: David Vrabel <david.vrabel@csr.com>
