2009-01-06uwb: safely remove all reservationsDavid Vrabel
When removing all reservations during shutdown, terminate them first and then wait for any pending timeout work to complete. This prevents the timeout work from running after the reservation has been freed. Signed-off-by: David Vrabel <david.vrabel@csr.com>

2008-12-12uwb: improved MAS allocator and reservation conflict handlingStefano Panella
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.

Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-11-19uwb: add basic radio managerDavid Vrabel
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>
2008-11-17uwb: add pal parameter to new reservation callbackDavid Vrabel
The pal parameter allows PALs to retrieve their PAL-specific data structure. Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-11-07uwb: fix races between events and neh timersDavid Vrabel
Always use del_timer_sync() before freeing nehs. Destroy all nehs after stopping the radio controller and before cleaning up the reservation manager. Handle the timer running after an event has removed the neh. This fixes various oopses that may occur if a radio controller is removed while a neh timer is still active. Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-11-07uwb: don't unbind the radio controller driver when resettingDavid Vrabel
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>
2008-11-04uwb: per-radio controller event thread and beacon cacheStefano Panella
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.

2008-11-04uwb: add commands to add/remove IEs to the debug interfaceStefano Panella

2008-10-28uwb: order IEs by element IDDavid Vrabel
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(). Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-10-28uwb: reference count reservationsDavid Vrabel
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. Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-10-28uwb: target reservations shouldn't get streamsDavid Vrabel

2008-10-20uwb: wrong sizeof argument in mac address compareFrank Leipold
In the __uwb_beca_find_bymac function the sizeof returns the length of a pointer and not the data it is referring to. Hence only the first 4 bytes were compared, not the entire 6 bytes MAC address. Now the sizeof takes struct uwb_mac_addr as argument. Signed-off-by: Frank Leipold <frank.leipold@eads.net> Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-10-16uwb: don't use printk_ratelimit() so oftenDavid Vrabel
Avoid using printk_ratelimit() in many places because: - many were error messages reporting broken hardware (it's useful to get all of these). - the message itself wasn't useful so the message has been removed. Signed-off-by: David Vrabel <david.vrabel@csr.com>

2008-09-17uwb: dont tranmit identification IEsDavid Vrabel

2008-09-17uwb: i1480/GUWA100U: fix firmware download issuesAnderson Lizardo
IOGear firmware versions >= 1.4.12224 fail to be downloaded because of a spurious (and harmless) RCEB received after the download notification. This patch handles this RCEB and keeps compatibility with future versions that might not emit this RCEB. i1480_rceb_check() is reused to check for the RCEB. It is also refactored with improved comments and reused in another place in mac.c where the checking was being duplicated. This patch was tested on both i1480 and GUWA100U HWAs, with all firmware versions currently available. Signed-off-by: Anderson Lizardo <anderson.lizardo@indt.org.br>
2008-09-17uwb: i1480: remove MAC/PHY information checking functionAnderson Lizardo
Some hardware/firmware combinations (most notably an IOGear HWA using the i1480 firmware) kill the host controller after issuing a GET_MAC_PHY_INFO command. Removing this check seems harmless otherwise. The patch fixes the issue where the HC is killed, showing the message: ehci_hcd 0000:00:1d.7: HC died; cleaning up After this error, USB comes back only after reloading the ehci_hcd module.

2008-09-17uwb: add Intel i1480 HWA to the UWB RC quirk tableAnderson Lizardo
The Intel i1480 HWA uses WHCI commands/events even though reporting itself as WUSB compliant.

The D-Link DUB-1210 HWA uses commands and events from the WHCI specification, although reporting itself as WUSB compliant. Therefore, we disable WUSB command/event filtering for it. USB_DEVICE_AND_INTERFACE_INFO is used for matching only the RC interface. Signed-off-by: Anderson Lizardo <anderson.lizardo@indt.org.br> Signed-off-by: David Vrabel <david.vrabel@csr.com>
