2009-04-02workqueue: add to_delayed_work() helper functionJean Delvare
It is a fairly common operation to have a pointer to a work and to need a pointer to the delayed work it is contained in. In particular, all delayed works which want to rearm themselves will have to do that. So it would seem fair to offer a helper function for this operation.

2009-03-24USB: allow libusb to talk to unauthenticated WUSB devicesDavid Vrabel
To permit a userspace application to associate with WUSB devices using numeric association, control transfers to unauthenticated WUSB devices must be allowed. This requires that wusbcore correctly sets the device state to UNAUTHENTICATED, DEFAULT and ADDRESS and that control transfers can be performed to UNAUTHENTICATED devices.

2009-01-06wusb: return -ENOTCONN when resetting a port with no connected deviceDavid Vrabel
If reading the device descriptor fails during hub_port_init() fails, then the port is disabled, disconnecting the device. The port is then reset at the start of the next init attempt but there is no device to reset. 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.

2008-11-25wusb: whci-hcd shouldn't do ASL/PZL updates while channel is inactiveDavid Vrabel
ASL/PZL updates while the WUSB channel is inactive (i.e., the PZL and ASL are stopped) may not complete. This causes hangs when removing the whci-hcd module if a device is still connected (removing the device does an endpoint_disable which results in an ASL update to remove the qset). If the WUSB channel is inactive the update can simply be skipped as the WHC doesn't care about the state of the ASL/PZL. 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>

2008-10-28wusb: reset WUSB devices with SetAddress(0)David Vrabel
Using a Reset Device IE to reset a WUSB device is too heavyweight as it causes the devcie to disconnect (which the USB stack does not expect and cannot handle). Instead, do a SetAddress(0); SetAddress(AuthAddr) for authenticated devices. Unauthenticated devices will not be reset and the stack will have to rely on the device timing out after TrustTimeout and disconnecting. Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-10-28wusb: do a proper channel stopDavid Vrabel
When stopping the WUSB channel the host should send Channel Stop IEs giving the WUSB Channel Time of the last MMC. Both WHCI and HWA hosts provide a channel stop command for this. Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-10-28wusb: disable verification of the key generation algorithmsDavid Vrabel
Verifing the key generation algorithms could take too long on a freshly booted system (due to lack of entropy) so disable the test unless a module parameter (debug_crypto_verify) is specified. 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>
2008-10-16uwb: don't use printk_ratelimit() so oftenDavid Vrabel
