This target IRAM recovery feature support is to copy target IRAM contents available at ATH10K_MEM_REGION_TYPE_REG to host memory for back up after firmware loaded. Target IRAM contents are copied to wmi memory chunks allocated for the WMI_IRAM_RECOVERY_HOST_MEM_REQ_ID and provide the wmi chunks address to the firmware through wmi init command. If firmware detects andy IRAM corruption through periodic checksum validation, It will download the IRAM contents back from the provided wmi memory chunks address using hif_memcpy. This IRAM recovery feature prevent target assert in case of unexpected target IRAM corruptions. This patch also introduce a new feature flag 'iram-recovery' for backward compatibility.

STS Beamformee capability sent from firmware is overwritten as num_tx_chains - 1. When num_tx_chains is 2, then STS is set to invalid value 1. Since STS is not limited by number of TX chain, not overwriting the capability received from firmware. Tested on: IPQ6018 WLAN.HK.2.4.0.1-00303-QCAHKSWPL_SILICONZ-1 Signed-off-by:

Current ring selector logic follows round-robin scheduling, when a process switch from one processor to another each time, the data in the cache would have to be invalidated and re-loaded from RAM leads to poor cache utilization. Therefore smp_processor_id() attempt to keep processes on the same processor via processor affinity which improves cache utilization. Also, ring selection could be chosen round robin when the processor_id based ring selection does not have the resources.

This patch calls wcn36xx_smd_keep_alive_req() on the STA patch immediately after associating with an AP. This will cause the firmware to send a NULL packet out to the AP every 30 seconds, thus offloading keep-alive processing from the SoC to the firmware. Signed-off-by:

The firmware parameter LINK_FAIL_TX_CNT maps to the prima configuration file parameter gLinkFailTxCnt and is described as: quote: " If within gLinkFailTimeout period(values is mentioned in msec) if FW doesn't receive acks for gLinkFailTxCnt number of packets, then link will be disconnected." The downstream description sets a minimum value of 1000 a maximum value of 60000 and a default value of 6000, however it appears that unless we actually set this value deliberately firmware defaults it to 0. Setting this value to non-zero results in the firmware doing link monitoring. The working example from downstream paradoxically sets the value to 200, here we opt to set the value to the minimum stipulated in the configuration file 1000. In conjunction with ieee80211_hw_set(wcn->hw, CONNECTION_MONITOR); this change effects offload of link monitoring to the firmware.

The ath11k code will try to insert wheather rader related limits when the DFS region is set to ETSI. For this reason, it will add two more entries in the array of reg_rules. But the 2.4.0.1 firmware is prefiltering the list of reg rules it returns for 2.4GHz PHYs. They will then not contain the list of 5GHz rules and thus no wheather radar band rules were inserted by this code. But the code didn't fix the n_reg_rules for this regulatory domain and PHY when this happened. This resulted in a rejection by is_valid_rd because it found rules which start and end at 0khz. This resulted in a splat like: Invalid regulatory domain detected ------------[ cut here ]------------ WARNING: at backports-20200628-4.4.60-9a94b73e75/net/wireless/reg.c:3721 [...] ath11k c000000.wifi1: failed to perform regd update : -22 The number of rules must therefore be saved after they were converted from the ath11k format to the ieee80211_regdomain format and not before.

cold boot calibration is the process to calibrate all the channels during the boot-up to avoid the calibration delay during the channel change. During the boot-up, firmware started in cold boot calibration mode Firmware calibrate all channels and generate CalDb(DDR). Subsequent wifi bringup will reuse the same CalDb. Firmware is restarted in normal mode to continue the normal operation. caldb memory address send to firmware through the QMI message.Firmware use this address to store the caldb data and use it until next reboot. This will give the improvement during the channel change. But it is increasing the boot-up time(up to 15sec depend on number of radios). So if the user want to reduce the boot-up time and accepting for channel change delay, user can disable this feature using the module param cold_boot_cal=0.

Board Data File (BDF) is loaded upon driver boot-up procedure. The right board data file is identified on IPQ6018 using bus, qmi-chip-id and qmi-board-id. The problem, however, can occur when the (default) board data file cannot fulfill with the vendor requirements and it is necessary to use a different board data file. This problem was already solved on ath10k by adding a ",variant=.*" at the end of the board name. The same functionality must also be provided for ath11k. The device tree requires an additional string to define the variant name wifi@c000000 { status = "okay"; qcom,ath11k-calibration-variant = "Cigtech-WF-188"; }; This would create the boarddata identifier for the board-2.bin search * bus=ahb,qmi-chip-id=0,qmi-board-id=18,variant=Cigtech-WF-188 Signed-off-by: -

The bus + qmi-chip-id + qmi-board-id is not enough to identify the correct board data file on IPQ6018 based devices. Multiple different boards share the same values. Only the original reference designs can currently be identified and loaded from the board-2.bin. But these will not result in the correct calibration data when combined with the pre-calibration data from the device. An additional "variant" information has to be provided to select the correct board data for a design which was modified by an ODM. This follows the same approach as ath10k. Signed-off-by:

This patch adds driver support for FILS discovery and unsolicited broadcast probe response transmission features which are used for in-band discovery in 6GHz band. Currently this support is enabled only in 6GHz by setting hardware flags. Changes include WMI commands to enable transmission, set packet interval, set template, and handle events. Signed-off-by:

The for loop checks whether cur_section is NULL on every iteration, but we know it can never be NULL as there is another check towards the bottom of the loop body. Refactor to avoid this unnecessary check. Also, increment the variable i inline for clarity Addresses-Coverity: 1496984 ("Null pointer dereferences) Suggested-by:Saeed Mahameed <saeedm@nvidia.com> Signed-off-by:
