2015-10-19ath10k: make fw stats prints specific to firmware versionManikanta Pubbisetty
The patch makes debug stats prints fw specific by adding a new member in wmi_ops. That way it's easier to add fw_stats support to 10.4 firmware.

2015-10-06ath10k: implement debugfs interface for Transmit Power Control statsMaharaja Kennadyrajan
The Transmit Power Control (TPC) dump will show the power control values for each rate which makes it easier to debug calibration problems. Example usage: # cat /sys/kernel/debug/ieee80211/phy0/ath10k/tpc_stats TPC config for channel 5180 mode 10 CTL = 0x10 Reg. Domain = 58 Antenna Gain = 1 Reg. Max Antenna Gain = 0 Power Limit = 34 Reg.

2015-05-22ath10k: enable pci soc powersavingMichal Kazior
By using SOC_WAKE register it is possible to bring down power consumption of QCA61X4 from 36mA to 16mA when associated and idle. Currently the sleep threshold/grace period is at a very conservative value of 60ms. Contrary to QCA61X4 the QCA988X firmware doesn't have Rx/beacon filtering available for client mode and SWBA events are used for beaconing in AP/IBSS so the SoC needs to be woken up at least every ~100ms in most cases. This means that QCA988X is at a disadvantage and the power consumption won't drop as much as for QCA61X4. Due to putting irq-safe spinlocks on every MMIO read/write it is expected this can cause a little performance regression on some systems. I haven't done any thorough measurements but some of my tests don't show any extreme degradation. The patch removes some explicit pci_wake calls that were added in 320e14b8db51aa ("ath10k: fix some pci wake/sleep issues"). This is safe because all MMIO accesses are now wrapped and the device is woken up automatically if necessary.

2015-01-13ath10k: Implement sta_add_debugfsRajkumar Manoharan
Add per station debugfs files when a station is added to mac80211's station list. This helps to group peer specific debugfs entries altogether. Right now this callback adds support to test aggregation procedures (addba/addba_resp/delba) manually. To enable automatic aggregation in target, echo 0 >/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/ stations/XX:XX:XX:XX:XX:XX/aggr_mode For manual mode, echo 1 >/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/ stations/XX:XX:XX:XX:XX:XX/aggr_mode Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

The logic responsible for processing the event is no different across different firmware binaries. The difference that needs to be dealt with is the ABI of data structures.

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>
2013-09-24ath: Remove extern from function prototypesJoe Perches
There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.
