| * ath10k: implement WMI events handling frame for both firmwaresBartosz Markowski2013-09-271-1/+130
| | | | | | | | | | | | | | | | We still use the same function handlers for both main and 10.X paths. Next step is to track down and make the split needed. Signed-off-by: Bartosz Markowski <bartosz.markowski@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
| * ath10k: warn if give WMI command is not supportedBartosz Markowski2013-09-271-0/+6
| | | | | | | | | | | | | | | | This will show and make it easier to track the API differences in the new AP firmware. Signed-off-by: Bartosz Markowski <bartosz.markowski@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
| * ath10k: add wmi_10x_<cmd/event> definitionsBartosz Markowski2013-09-271-2/+124
| | | | | | | | | | | | | | | | | | Introduce the cmd and events definitions for 10.X FW API and make up the wmi_10x_cmd_map. This is the core of host-firmware WMI interface for 10.X FW branch.

| * ath10k: introduce dynamic WMI structuresBartosz Markowski2013-09-271-41/+189
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the initial framework to implement dynamic WMI API in order to support new firmware (from so called 10.X branch) The realization is to have a static WMI cmd map for each of the firmwares, registered upom wmi init. This patch creates such map for MAIN FW, updates wmi_cmd_send() calls to take as a parameter the map value instead of direct WMI enum. As soon as complete 10.X API will be on place, we will introduce the FW IE mechanics to dynamicaly identify which FW is being used and based on that we will use correct map, API, structures, etc. Signed-off-by: Bartosz Markowski <bartosz.markowski@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

John W. Linville says: ==================== Regarding the Bluetooth bits, Gustavo says: "The big work here is from Marcel and Johan. They did a lot of work in the L2CAP, HCI and MGMT layers. The most important ones are the addition of a new MGMT command to enable/disable LE advertisement and the introduction of the HCI user channel to allow applications to get directly and exclusive access to Bluetooth devices." As to the ath10k bits, Kalle says: "Bartosz dropped support for qca98xx hw1.0 hardware from ath10k, it's just too much to support it. Michal added support for the new firmware interface. Marek fixed WEP in AP and IBSS mode. Rest of the changes are minor fixes or cleanups." And also: "Major changes are: * throughput improvements including aligning the RX frames correctly and optimising HTT layer (Michal) * remove qca98xx hw1.0 support (Bartosz) * add support for firmware version 999.999.0.636 (Michal) * firmware htt statistics support (Kalle) * fix WEP in AP and IBSS mode (Marek) * fix a mutex unlock balance in debugfs file (Shafi) And of course there's a lot of smaller fixes and cleanup." For the wl12xx bits, Luca says: "Here are some patches intended for 3.13. Eliad is upstreaming a bunch of patches that have been pending in the internal tree. Mostly bugfixes and other small improvements." Along with that... Arend and friends bring us a batch of brcmfmac updates, Larry Finger offers some rtlwifi refactoring, and Sujith sends the usual batch of ath9k updates. As usual, there are a number of other small updates from a variety of players as well. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
| * ath10k: remove wmi event worker threadMichal Kazior2013-09-161-43/+1
| | | | | | | | | | | | | | | | | | It's not really necessary to have this processed in a worker. There are no sleepable calls (and actually shouldn't be). Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
| * ath10k: remove wmi pending count limitMichal Kazior2013-09-161-32/+0

| * ath10k: improve beacon submission latencyMichal Kazior2013-09-161-13/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | The patch prevents beacon misses in some case of heavy load on a system. If a beacon can't be transmitted directly from an SWBA event it will be left in arvif->beacon and transmission will be retried once TX credits become available.

| * ath10k: simplify HTC command submittingMichal Kazior2013-09-161-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch removes HTC endpoint tx workers in favour of direct command submission. This makes a lot more sense for data path. mac80211 queues are effectively stopped/woken up in a more timely fashion preventing build up of frames. It's possible to push more traffic than the device/system is able to handle and have no hiccups or performance degradation with UDP traffic. WMI commands will now report errors properly and possibly block as they actively can wait for tx credits to become available.

| * ath10k: make WMI commands block by designMichal Kazior2013-09-161-20/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will be necessary for further changes in command submission scheme. Once HTC is cleaned up WMI commands will finally block. This requires for SWBA to be processed in a non-atomic context for now. Once other necessary changes are in this will be reverted.

| * ath10k: add support for firmware newer than 636Michal Kazior2013-08-151-8/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The mgmt_rx event structure has been expanded. Since the structure header is expanded the payload (i.e. mgmt frame) is shifted by a few bytes. This needs to be taken into account in order to support both old and new firmware. This introduces a fw_features to keep track of any FW-related ABI/behaviour changes.

| | | | | | | | | | | | | | | | Restart the hardware if FW crashes. If FW crashes during recovery we leave the hardware in a "wedged" state to avoid recursive recoveries. When in "wedged" state userspace may bring interfaces down (to issue stop()) and then bring one interface (to issue start()) to reload hardware manually.

* ath10k: mac80211 driver for Qualcomm Atheros 802.11ac CQA98xx devicesKalle Valo2013-06-121-0/+2081
Here's a new mac80211 driver for Qualcomm Atheros 802.11ac QCA98xx devices. A major difference from ath9k is that there's now a firmware and that's why we had to implement a new driver. The wiki page for the driver is: http://wireless.kernel.org/en/users/Drivers/ath10k The driver has had many authors, they are listed here alphabetically: Bartosz Markowski <bartosz.markowski@tieto.com> Janusz Dziedzic <janusz.dziedzic@tieto.com> Kalle Valo <kvalo@qca.qualcomm.com> Marek Kwaczynski <marek.kwaczynski@tieto.com> Marek Puzyniak <marek.puzyniak@tieto.com> Michal Kazior <michal.kazior@tieto.com> Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
