* libertas: add asynchronous firmware loading capabilityDaniel Drake2012-04-171-0/+8
| | | | | | | | | | | | | | | | | | As described at http://article.gmane.org/gmane.linux.kernel.wireless.general/86084 libertas is taking a long time to load because it loads firmware during module loading. Add a new API for interface drivers to load their firmware asynchronously. The same semantics of the firmware table are followed like before. Interface drivers will be converted in follow-up patches, then we can remove the old, synchronous firmware loading function.

* libertas: Firmware loading simplificationsDaniel Drake2012-04-171-2/+1
| | | | | | | | | | | | | | | | | | | | | | Remove the ability to pass module parameters with firmware filenames for USB and SDIO interfaces. Remove the ability to pass custom "user" filenames to lbs_get_firmware(). Remove the ability to reprogram internal device memory with a different firmware from the USB driver (we don't know of any users), and simplify the OLPC firmware loading quirk to simply placing the OLPC firmware at the top of the list (we don't know of any users other than OLPC). Move lbs_get_firmware() into its own file. These simplifications should have no real-life effect but make the upcoming transition to asynchronous firmware loading considerably less painful.

* libertas: fix changing interface type when interface is downDaniel Drake2011-10-141-0/+2
| | | | | | | | | | | | | | The recent changes to only power the device when the interface up introduced a bug: changing interface type, legal when the interface is down, performs device I/O. Fix this functionality by validating and recording the interface type when the change is requested, but only applying the change if/when the interface is brought up.

* libertas: disable functionality when interface is downDaniel Drake2011-08-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | Modify the driver so that it does not function when the interface is down, in preparation for runtime power management. No commands can be run while the interface is down, so the ndo_dev_stop routine now directly does all necessary work (including asking the device to disconnect from the network and disabling multicast functionality) directly. power_save and power_restore hooks are added meaning that card drivers can take steps to turn the device off when the interface is down. The MAC address can now only be changed when all interfaces are down; the new address will be programmed when an interface gets brought up. This matches mac80211 behaviour. Also, some small cleanups/simplifications were made in the surrounding device handling logic. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* libertas: add two-stage firmware request helperDan Williams2010-08-161-0/+13
| | | | | | | | | | | | | | | SDIO, GSPI, and CS all use 2-stage firmware and the loading process and logic should be the same. Allow module parameters to override the automatic firmware choice, otherwise just walk the bus driver's firmware table and pick out the first firmware pair that exists for the given model. Some special care is taken to allow overriding of just the helper or the main firmware, but let the other of the pair be chosen automatically.

* Libertas: Added 11d support using cfg80211Kiran Divekar2010-06-231-0/+5
| | | | | | | | | | | | | | | | Added 11d support for libertas driver using cfg80211. This is based on Holger Shurig's initial work to add cfg80211 support libertas. (https://patchwork.kernel.org/patch/64286/) Please let us know, if there are any improvements comments. Code is added to send 11d enable command to firmware while initialisation and pass 11d specific information to firmware when notifier handler is called by cfg80211.

* libertas: Added callback functions to support SDIO suspend/resume.Amitkumar Karwar2010-06-021-1/+1
| | | | | | | | | | | | In suspend() host sleep is activated using already configured host sleep parameters through wol command, and in resume() host sleep is cancelled.

* libertas: convert libertas driver to use an event/cmdresp queueHolger Schurig2008-04-161-4/+6
| | | | | | | | | | | | | | | This patch (co-developed by Dan Williams and Holger Schurig) uses a kfifo object for events and a swapping buffer scheme for the command response to preserve the zero-copy semantics of the CF driver and keep memory usage low. The main thread should only ever touch the buffer indexed by priv->resp_idx, while the interface code is free to write to the second buffer, then swap priv->resp_idx under the driver spinlock. The firmware specs only permit one in-flight command, so there will only ever be one command response to process at a time.

* [PATCH] libertas: reorganize and simplify init sequenceDan Williams2007-10-101-1/+2
| | | | | | | | | | | | | | | | | | This patch moves all firmware load responsibility into the interface-specific code and gets rid of the firmware pointer in the generic card structure. It also removes 3 fairly unecessary callbacks: hw_register_dev, hw_unregister_dev, and hw_prog_firmware. It also makes the init sequence from interface probe functions more logical, as there are paired add/remove and start/stop calls into generic libertas code. Because the USB driver code uses the same TX URB callback for both firmware upload (where the generic libertas structure isn't initialized yet) and for normal operation (where it is), some bits of USB code have to deal with 'priv' being NULL. All USB firmware upload bits have been changed to not require 'priv' at all, but simply the USB card structure. Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.
