2016-04-20ath10k: refactor firmware images to struct ath10k_fw_componentsKalle Valo6-137/+199
To make it easier to share ath10k_core_fetch_board_data_api_n() with testmode.c refactor all firmware components to struct ath10k_fw_components. This structure will hold firmware related files, for example firmware-N.bin and board-N.bin. For firmware-N.bin create a new struct ath10k_fw_file which contains the actual firmware image as well as the parsed data from the image. Modify ath10k_core_start() to take struct ath10k_fw_components() as an argument which makes it possible in following patches to drop some ugly hacks from testmode.c.

2016-04-19ath9k: interpret requested txpower in EIRP domainZefir Kurtisi1-8/+2
Tx power limitations at upper layers are interpreted in the EIRP domain. When the user requests a given maximum txpower, e.g. with: 'iw phy0 set txpower fixed 1500', he expects the EIRP to be at or below 15dBm. In ath9k_hw_apply_txpower(), the interpretation is different: the antenna-gain is capped against the current txpower limit in the regulatory, but not against the user set value. It ensures that the resulting EIRP is below the limit defined by the active countrycode, but not below the value the user requested. In a scenario like e.g. a) antenna_gain=6 b) countrycode limits to eirp=18 c) user set txpower=15 this will cause a setting for AR_PHY_POWER_TX_RATE regs resulting in an EIRP > 15. This patch ensures that antenna-gain is considered whenever the txpower limit is adjusted and with that the user set limits are kept.

2016-04-19ath10k: add dynamic tx mode switch config support for qca4019Raja Mani4-2/+37
push-pull mode needs certain amount the host driver involvement for managing queues in the host memory and packet delivery to firmware. qca4019 wifi firmware has an option to stay in push mode for less number of active traffic flow and then switch to push-pull mode when the active traffic flow goes beyond the certain limit. The advantage of staying in push mode for less active traffic is, the host cpu consumption is reduced. qca4019 firmware supports this flexibility of the mode switch. It takes the host driver interest (LOW_PERF/HIGH_PERF) via WMI_EXT_RESOURCE_CFG_CMDID, LOW_PERF - fw would stay in push mode and switch to push-pull based on demand. HIGH_PERF - fw would stay in push-pull mode from the boot. To make this configuration generic, new WMI services WMI_SERVICE_TX_MODE_PUSH_ONLY, WMI_SERVICE_TX_MODE_PUSH_PULL, WMI_SERVICE_TX_MODE_DYNAMIC are introduced to take dynamic tx mode switch support availability in firmware. Based on WMI_SERVICE_TX_MODE_DYNAMIC, LOW_PERF or HIGHT_PERF is configured to the firmware.

2016-04-19ath10k: fix rx_channel during hw reconfigureRajkumar Manoharan1-1/+7
Upon firmware assert, restart work will be triggered so that mac80211 will reconfigure the driver. An issue is reported that after restart work, survey dump data do not contain in-use (SURVEY_INFO_IN_USE) info for operating channel. During reconfigure, since mac80211 already has valid channel context for given radio, channel context iteration return num_chanctx > 0. Hence rx_channel is always NULL. Fix this by assigning channel context to rx_channel when driver restart is in progress.

Return value is incorrect for btcoex and peer stats debugfs 'write' entries if the user provides a value that matches with the already available debugfs entry, this results in the debugfs entry getting stuck and the operation has to be terminated manually.
