* ath11k: avoid null pointer dereference when pointer band is nullColin Ian King2020-01-261-4/+4
| | | | | | | | | | | | | In the unlikely event that cap->supported_bands has neither WMI_HOST_WLAN_2G_CAP set or WMI_HOST_WLAN_5G_CAP set then pointer band is null and a null dereference occurs when assigning band->n_iftype_data. Move the assignment to the if blocks to avoid this. Cleans up static analysis warnings.

* ath11k: set TxBf parameters after vdev startBhagavathi Perumal S2020-01-261-6/+5
| | | | | | | | | | The channel info parameters are required by the firmware to process TxBf parameters. Currently TxBf is passed prior to the channel info. This patch moves TxBf setup after the channel setup.

* ath11k: fix debugfs build failureArnd Bergmann2020-01-261-1/+1
| | | | | | | | | | | | | | | | | When CONFIG_ATH11K_DEBUGFS is disabled, but CONFIG_MAC80211_DEBUGFS is turned on, the driver fails to build: drivers/net/wireless/ath/ath11k/debugfs_sta.c: In function 'ath11k_dbg_sta_open_htt_peer_stats': drivers/net/wireless/ath/ath11k/debugfs_sta.c:416:4: error: 'struct ath11k' has no member named 'debug' ar->debug.htt_stats.stats_req = stats_req; ^~ It appears that just using the former symbol is sufficient here, adding a Kconfig dependency takes care of the corner cases.

* ath11k: register HE mesh capabilitiesSven Eckelmann2019-12-171-0/+75
| | | | | | | | | | | | The capabilities for the HE mesh are generated from the capabilities reported by the fw. But the firmware only reports the overall capabilities and not the one which are specific for mesh. Some of them (TWT, MU UL/DL, TB PPDU, ...) require an infrastructure setup with a main STA (AP) controlling the operations. This is not the case for mesh and thus these capabilities are removed from the list of capabilities.

* ath11k: Move mac80211 hw allocation before wmi_init commandVasanthakumar Thiagarajan2019-11-291-36/+61
| | | | | | | | | | | | | This is to prepare REO ring setup before sending wmi_init command. Firmware expects all the required REO rings to be setup while processing wmi_init command. But as per the current initialization sequence, REO ring configurations are done only after wmi_init command is sent. Also refactoring ath11k_mac_create() into ath11k_mac_alloc() and ath11k_mac_register() to it mac80211 hw structure available before sending wmi_init command.

* ath11k: add support for controlling tx power to a stationMaharaja Kennadyrajan2019-11-291-0/+37
| | | | | | | | | | | | | | | | | | | | This patch will add the support to control the transmit power for traffic to a station associated with the AP. Underlying firmware will enforce that the maximum tx power will be based on the regulatory requirements. If the user given transmit power is greater than the allowed tx power in the given channel, then the firmware will use the maximum tx power in the same channel. Max and Min tx power values will depends on number of tx chain masks. The allowed tx power range values are from 6 to 23. When 0 is sent to the firmware as tx power, it will revert to the default tx power for the station.

* ath11k: driver for Qualcomm IEEE 802.11ax devicesKalle Valo2019-11-251-0/+5427
ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k uses mac80211 and supports AP, Station and Mesh modes. Even though ath11k has some similar code as with ath10k (especially the WMI layer) it was concluded to be simpler to have a "clean start" for ath11k code base and not try to share the code with ath10k. This makes maintenance easier and avoids major changes in ath10k, which would have significantly increased the risk of regressions in existing setups. Even though the driver is very similar with ath10k but there are major differences as well. The datapath is completely different. ath11k supports multiple MACs, called "soc" in the firmware interface. And there's only one WMI interface to support. Currently ath11k supports only IEEE 802.11ac mode, but patches for 802.11ax are available and they will be submitted after ath11k is accepted to upstream. The firmware images are available from ath11k-firmware repository but they will be also submitted to linux-firmware: https://github.com/kvalo/ath11k-firmware This was tested with firmware version WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1.
