* ath9k: Process GTT interruptsSujith Manoharan2014-01-13
| | | | | | | | | | | | | | | | | Global Transmission Timeout interrupts are generated by the HW when transmission of a frame fails - this is done based on the threshold programmed in the AR_GTXTO register. Currently, even though the interrupt is enabled for all chips, it is not handled in the driver. This patch handles GTT events for AR9003 and above chips, checking if the MAC/BB has hung after successive GTT interrupts crosses a threshold (5). This can be enabled for the older chips in the AR9002 family once appropriate HW hang checks are implemented for them.

* ath9k: Remove RX PollSujith Manoharan2014-01-03
| | | | | | | | | | | | This patch removes the convoluted and hacky method of monitoring for connectivity. We rely on mac80211's connection loss logic and doing it in the driver is not necessary. The HW check for MAC/BB hangs is also simplified, there is no need to have a separate work instance for it. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

* ath9k: use a timer to put hardware into full sleepFelix Fietkau2013-12-02
| | | | | | | | | | | | When operating in client mode, the short period of time between scanning and associating is often enough to put the hardware through several FULL-SLEEP <-> AWAKE transitions, each wakeup requiring a reset to fully recover the hardware. This is completely unnecessary and can easily be avoided by deferring the switch to full sleep. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ath9k: Fix TX99 config option usageSujith Manoharan2013-12-02
| | | | | | | | | | | | | | Use CONFIG_ATH9K_TX99 to properly enclose the tx99 code and make sure that it is not compiled as part of the driver when it is not selected. Move the tx99 code to a new file tx99.c and also add ATH9K_DEBUGFS as a dependency in Kconfig. This reduces the module size on platforms like OpenWrt where ATH9K_DEBUGFS is selected, but TX99 might be disabled. Cc: Luis R.

* ath9k: Use correct PCIE initvals for AR9485Sujith Manoharan2013-11-11
| | | | | | | | | | | | | | | | | Currently, the PLL is turned off for AR9485 when switching to a low power state, but AR9485 has an issue where the card will become unresponsive if left idle for a long time without any traffic. To fix this, force the PLL to always be on using a different initval array, ar9485_1_1_pll_on_cdr_on_clkreq_disable_L1. This is done for most of the AR9485 based cards like HB125, WB225 etc. but certain models require the feature to be turned off. Identify such cards and use default values for them.

SAR is the unit of measurement for the amount of radio frequency(RF) absorbed by the body when using a wireless device. The RF exposure limits used are expressed in the terms of SAR, which is a measure of the electric and magnetic field strength and power density for transmitters operating at frequencies from 300 kHz to 100 GHz. Regulatory bodies around the world require that wireless device be evaluated to meet the RF exposure limits set forth in the governmental SAR regulations.

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>

* ath9k: use software queues for un-aggregated data packetsFelix Fietkau2013-08-09
| | | | | | | | | | | | | | | | | This is a first step for improving fairness between legacy and 802.11n traffic, and it should also improve reliability of resets and channel changes by keeping the hardware queue depth very short. When an aggregation session is torn down, all packets in the retry queue will be removed from the BAW and freed. For all subframes that have not been transmitted yet, the A-MPDU flag will be cleared, and a sequence number allocated. This ensures that the next A-MPDU session will get the correct initial sequence number. This happens both on aggregation session start and stop.
