2024-02-15wifi: ath11k: add support for QCA2066Baochen Qiang
QCA2066 is a PCI based DBS device. It is very similar to WCN6855 overall: they share the same PCI device ID, the same major and minor version numbers, the same register address, and same HAL descriptors etc. The most significant difference is that QCA2066 supports 3-antenna configuration while WCN6855 does not. To differentiate them, subversion numbers are used. Currently four numbers are used by QCA2066: 0x1019A0E1, 0x1019B0E1, 0x1019C0E1 and 0x1019D0E1.

2023-10-25wifi: ath11k: add firmware-2.bin supportAnilkumar Kolli
Firmware IE containers can dynamically provide various information what firmware supports. Also it can embed more than one image so updating firmware is easy, user just needs to update one file in /lib/firmware/. The firmware API 2 or higher will use the IE container format, the current API 1 will not use the new format but it still is supported for some time. Firmware API 2 files are named as firmware-2.bin (which contains both amss.bin and m3.bin images) and API 1 files are amss.bin and m3.bin. Currently ath11k PCI driver provides firmware binary (amss.bin) path to MHI driver, MHI driver reads firmware from filesystem and boots it. Add provision to read firmware files from ath11k driver and provide the amss.bin firmware data and size to MHI using a pointer. Currently enum ath11k_fw_features is empty, the patches adding features will add the flags. With AHB devices there's no amss.bin or m3.bin, so no changes in how AHB firmware files are used. But AHB devices can use future additions to the meta data, for example in enum ath11k_fw_features.

2023-10-12wifi: ath11k: Introduce and use ath11k_sta_to_arsta()Jeff Johnson
Currently, the logic to return an ath11k_sta pointer, given a ieee80211_sta pointer, uses typecasting throughout the driver. In general, conversion functions are preferable to typecasting since using a conversion function allows the compiler to validate the types of both the input and output parameters. ath11k already defines a conversion function ath11k_vif_to_arvif() for a similar conversion. So introduce ath11k_sta_to_arsta() for this use case, and convert all of the existing typecasting to use this function. No functional changes, compile tested only.

2023-06-01wifi: ath11k: factory test mode supportGovindaraj Saminathan
Add support to process factory test mode commands (FTM) for calibration. By default firmware start with NORMAL mode and to process the FTM commands firmware needs to be restarted in FTM mode using module parameter ftm_mode. The pre-request is all the radios should be down before starting the test. When start command ATH11K_TM_CMD_TESTMODE_START is received, ar->state is set to Test Mode. If the FTM command or event length is greater than 256 bytes, it will be broken down into multiple segments and encoded with TLV header if it is segmented commands, else it is sent to firmware as it is. On receiving UTF event from firmware, if it is segmented event, the driver will wait until it receives all the segments and notify the complete data to user application. In case the segmented sequence are missed or lost from the firmware, driver will skip the already received partial data. In case of unsegmented UTF event from firmware, driver notifies the data to the user application as it comes. Applications handles the data further.

This directory created under the top-level ath11k directory, for example /sys/kernel/debug/ath11k. The reference to the toplevel ath11k directory is not stored anymore within ath11k, instead it's retrieved using debugfs_lookup(). If the directory does not exist it will be created. After the last directory from the ath11k directory is removed, for example when doing rmmod ath11k, the empty ath11k directory is left in place, it's a minor cosmetic issue anyway. Here's an example hierarchy with one WCN6855: ath11k `-- pci-0000:06:00.0 |-- mac0 | |-- dfs_block_radar_events | |-- dfs_simulate_radar | |-- ext_rx_stats | |-- ext_tx_stats | |-- fw_dbglog_config | |-- fw_stats | | |-- beacon_stats | | |-- pdev_stats | | `-- vdev_stats | |-- htt_stats | |-- htt_stats_reset | |-- htt_stats_type | `-- pktlog_filter |-- simulate_fw_crash `-- soc_dp_stats I didn't have a test setup where I could connect multiple ath11k devices to the same the host, so I have only tested this with one device.

2022-10-12wifi: ath11k: fix firmware assert during bandwidth change for peer staAditya Kumar Singh
Currently, ath11k sends peer assoc command for each peer to firmware when bandwidth changes. Peer assoc command is a bulky command and if many clients are connected, this could lead to firmware buffer getting overflowed leading to a firmware assert. However, during bandwidth change, only phymode and bandwidth also can be updated by WMI set peer param command. This makes the overall command light when compared to peer assoc and for multi-client cases, firmware buffer overflow also does not occur. Remove sending peer assoc command during sta bandwidth change and instead add sending WMI set peer param command for phymode and bandwidth.

2022-09-28wifi: ath11k: stop tx queues immediately upon firmware exitAditya Kumar Singh
Currently, recovery flag is set immediately upon firmware exit but tx queues are stopped once firmware arrives back and is ready which is during ath11k_core_restart. Once ieee80211 hw restart is completed, tx queues are resumed. If during the time delta between firmware exit and firmware ready, mac80211 send packets, currently ath11k will drop it since recovery flag will be set. But warning prints will come - "ath11k c000000.wifi: failed to transmit frame -108" If more tx packets are there, this could lead to flooding of above print. However, actually tx queues should be stopped immediately when firmware leaves. This will prevent packets to get dropped when firmware is recovering.

2022-06-06ath11k: Fix LDPC config in set_bitrate_mask hookManikanta Pubbisetty
Currently ar->ht_cap_info is not set anywhere in the code, this could result in LDPC config computed wrongly in the set_bitrate_mask() hook and eventually sending wrong config to the target. Fix this by checking the LDPC support from the band HT capabilities of the radio instead. Furthermore, it looks like firmwares running on the ath11k hardware do not set WMI_HT_CAP_LDPC for advertising the TX LDPC capability, WMI_HT_CAP_TX_LDPC is set instead and this should be checked for getting hardware's TX LDPC support. This is true for QCA6390, WCN6855 & WCN6750 hardware. Also, remove unused variables ht_cap_info & vht_cap_info from struct ath11k{}. Found this during code review.

2022-05-02ath11k: Add support for WCN6750 deviceManikanta Pubbisetty
WCN6750 is non-DBS 2x2 11AX chipset. Unlike QCA6390 which is a DBS (dual band simultaneous) solution (2 LMACs), WCN6750 has a single LMAC supporting 2G, 5G and 6G bands but will operate only on one band at any given point. WCN6750 is a PCIe based solution, but it is attached to the WPSS (Wireless Processor SubSystem) Q6 processor, hence it is enumerated by the Q6 processor. It is registered to the APSS processor (Application Processor SubSystem) as a platform device(AHB) and remoteproc APIs are used to boot up or shutdown the device like other AHB devices. Also, Device information like BAR and it's size is not known to the APSS processor as the chip is enumerated by WPSS Q6. These details are fetched over QMI. STA and AP modes are supported. Verified basic connectivity and ping in both the modes. An important point to note is that though WCN6750 is a PCIe device, it cannot be attached to any other platform except on Qualcomm Snapdragon SoCs due to the aforementioned reasons.

2022-05-02ath11k: Add HW params for WCN6750Manikanta Pubbisetty
WCN6750 is a PCIe based solution that is attached to and enumerated by the WPSS (Wireless Processor SubSystem) Q6 processor. Though it is a PCIe device, since it is not attached to APSS processor (Application Processor SubSystem), APSS will be unaware of such a decice and hence it is registered to the APSS processor as a platform device(AHB). Because of this hybrid nature, it is called as a hybrid bus device. A new variable hybrid_bus_type is defined in hw_params to indicate the hybrid nature of the device. Add HW params for WCN6750.

2022-05-02ath11k: Move parameters in bus_params to hw_paramsManikanta Pubbisetty
In ath11k, bus_params were added with an intention to hold parameters related to bus (AHB/PCI), but this is not true as some bus parameters being different between chipsets of the same bus. With the addition of WCN6750 to ath11k, bus parameters are going to be entirely different among AHB devices. Therefore, it is wise to move bus_params to hw_params and get rid of bus_params entirely. Also, mhi_support parameter is not used anywhere in the driver, remove it from bus_params.

Remove core PCI and ath11k PCI references(struct ath11k_pci) from PCI common code. Since, PCI common code will be used by hybrid bus devices, this code should be independent from ATH11K PCI references and Linux core PCI references like struct pci_dev. Since this change introduces function callbacks for bus wakeup and bus release operations, wakeup_mhi HW param is no longer needed and hence it is removed completely. Alternatively, bus wakeup/release ops for QCA9074 are initialized to NULL as QCA9704 does not need bus wakeup/release for register accesses.

2022-03-30ath11k: reduce the wait time of 11d scan and hw scan while add interfaceWen Gong
Currently ath11k will wait 11d scan complete while add interface in ath11k_mac_op_add_interface(), when system resume without enable wowlan, ath11k_mac_op_add_interface() is called for each resume, thus it increase the resume time of system. And ath11k_mac_op_hw_scan() after ath11k_mac_op_add_interface() also needs some time cost because the previous 11d scan need more than 5 seconds when 6 GHz is enabled, then the scan started event will indicated to ath11k after the 11d scan completed. While 11d scan/hw scan is running in firmware, if ath11k update channel list to firmware by WMI_SCAN_CHAN_LIST_CMDID, then firmware will cancel the current scan which is running, it lead the scan failed. The patch commit 9dcf6808b253 ("ath11k: add 11d scan offload support") used finish_11d_scan/finish_11d_ch_list/pending_11d to synchronize the 11d scan/hw scan/channel list between ath11k/firmware/mac80211 and to avoid the scan fail. Add wait operation before ath11k update channel list, function ath11k_reg_update_chan_list() will wait until the current 11d scan/hw scan completed. And remove the wait operation of start 11d scan and waiting channel list complete in hw scan. After these changes, resume time cost reduce about 5 seconds and also hw scan time cost reduced obviously, and scan failed not seen. The 11d scan is sent to firmware only one time for each interface added in mac.c, and it is moved after the 1st hw scan because 11d scan will cost some time and thus leads the AP scan result update to UI delay. Currently priority of ath11k's hw scan is WMI_SCAN_PRIORITY_LOW, and priority of 11d scan in firmware is WMI_SCAN_PRIORITY_MEDIUM, then the 11d scan which sent after hw scan will cancel the hw scan in firmware, so change the priority to WMI_SCAN_PRIORITY_MEDIUM for the hw scan which is in front of the 11d scan, thus it will not happen scan cancel in firmware.

2022-03-25ath11k: Add peer rhash table supportKarthikeyan Periyasamy
When more clients (128) are connected, the UL data traffic KPI measurement is low compared to single client. This issue is due to more CPU cycles spent on the peer lookup operation with more clients. So reduce the peer lookup operation by modifying the linear based lookup operation into the rhash based lookup operation. This improve the peak throughput measurement.

ath11k_base ieee80211_reconfig() of mac80211 is the main function for recovery of each ieee80211_hw and ath11k, and ath11k_core_reconfigure_on_crash() is the main function for recovery of ath11k_base, it has more than one ieee80211_hw and ath11k for each ath11k_base, so it need to add synchronization between them, otherwise it has many issue. For example, when ath11k_core_reconfigure_on_crash() is not complete, mac80211 send a hw scan request to ath11k, it leads firmware crash, because firmware has not been initialized at that moment, firmware is only finished downloaded and loaded, it can not receive scan command.

2022-03-23ath11k: add support for device recovery for QCA6390/WCN6855Wen Gong
Currently ath11k has device recovery logic, it is introduced by this patch "ath11k: Add support for subsystem recovery" which is upstream by https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=ath11k-bringup&id=3a7b4838b6f6f234239f263ef3dc02e612a083ad. The patch is for AHB devices such as IPQ8074, it has remote proc module which is used to download the firmware and boots the processor which firmware is running on. If firmware crashed, remote proc module will detect it and download and boot firmware again. Below command will trigger a firmware crash, and then user can test feature of device recovery. Test command: echo assert > /sys/kernel/debug/ath11k/qca6390\ hw2.0/simulate_fw_crash echo assert > /sys/kernel/debug/ath11k/wcn6855\ hw2.0/simulate_fw_crash Unfortunately, QCA6390 is PCIe bus, it does not have the remote proc module, it use mhi module to communicate between firmware and ath11k. So ath11k does not support device recovery for QCA6390 currently. This patch is to add the extra logic which is different for QCA6390. When firmware crashed, MHI_CB_EE_RDDM event will be indicate by firmware and then ath11k_mhi_op_status_cb which is the callback of mhi_controller will receive the MHI_CB_EE_RDDM event, then ath11k will start to do recovery process, ath11k_core_reset() calls ath11k_hif_power_down()/ath11k_hif_power_up(), then the mhi/ath11k will start to download and boot firmware. There are some logic to avoid deadloop recovery and two simultaneous recovery operations. And because it has muti-radios for the soc, so it add some logic in ath11k_mac_op_reconfig_complete() to make sure all radios has reconfig complete and then complete the device recovery. Also it add workqueue_aux, because ab->workqueue is used when receive ATH11K_QMI_EVENT_FW_READY in recovery process(queue_work(ab->workqueue, &ab->restart_work)), and ath11k_core_reset will wait for max ATH11K_RESET_TIMEOUT_HZ for the previous restart_work finished, if ath11k_core_reset also queued in ab->workqueue, then it will delay restart_work of previous recovery and lead previous recovery fail. ath11k recovery success for QCA6390/WCN6855 after apply this patch.

2022-02-01ath11k: Add debugfs interface to configure firmware debug log levelSeevalamuthu Mariappan
Add debugfs interface "fw_dbglog_config" to configure firmware log level. Configuration is done via WMI command WMI_DBGLOG_CFG_CMDID. Command to configure, echo "<dbglog_param> <values>" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config where dbglog_param can be, 1) WMI_DEBUG_LOG_PARAM_LOG_LEVEL - configure log level for a given module here, <values> = <0xaaaa00bb>, 'aaaa' - module id and 'bb' - loglevel 2) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE - enable debug log for a given vdev here, <values> = vdev_id 3) WMI_DEBUG_LOG_PARAM_VDEV_DISABLE - disable debug log for a given vdev except ERROR logs here, <values> = vdev_id 4) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE_BITMAP - set vdev enable bitmap here, <values> = vdev_enable_bitmap 5) WMI_DEBUG_LOG_PARAM_MOD_ENABLE_BITMAP - set a given log level to all the modules specified in the module bitmap. Command to configure for this log param, $ echo "5 <values> <module_id_index> <is_end>" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config here, <values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and 'bb' - loglevel <module_id_index> = index of module bitmap. Max module id is 512. So, module_id_index is 0-15. <is_end> = to indicate if more configuration to follow. 6) WMI_DEBUG_LOG_PARAM_WOW_MOD_ENABLE_BITMAP - Wow mode specific logging enable. Command to configure for this log param, $ echo "6 <values> <module_id_index> <is_end>" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config here, <values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and 'bb' - loglevel <module_id_index> = index of module bitmap. Max module id is 512. So, module_id_index is 0-15. <is_end> = to indicate if more configuration to follow. Sample command usage, To enable module WLAN_MODULE_WMI and log level ATH11K_FW_DBGLOG_VERBOSE, echo "1 0x10001" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config To enable module bit map from 32 to 63 and log level ATH11K_FW_DBGLOG_VERBOSE, echo "5 0xffffffff00000001 1 1" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01734-QCAHKSWPL_SILICONZ-1 Signed-off-by: Seevalamuthu Mariappan <quic_seevalam@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://lore.kernel.org/r/1642405103-32302-1-git-send-email-quic_seevalam@quicinc.com
2022-01-17ath11k: Reconfigure hardware rate for WCN6855 after vdev is startedBaochen Qiang
There is an issue that WCN6855 tries to connect to an AP using a hardware rate of 1Mb/s , even though the AP has announced expected rates as [24, 36, 48, 54] in Probe Response frame. The reason is that WCN6855 firmware clears hardware rate info of management frames when vdev starts and uses 1Mb/s as default. To solve it, reconfigure the rate after vdev is started.
