I have received feedback that QCA6390 PCI support is working for many, and I'm also using QCA6390 on my daily driver^Hlaptop. While there are issues still to be resolved it's not really experimental anymore, so remove the experimental warning from driver initialisation.

ieee80211_find_sta_by_ifaddr() must be called under the RCU lock and the resulting pointer is only valid under RCU lock as well. Fix ath10k_wmi_tlv_op_pull_peer_stats_info() to hold RCU lock before it calls ieee80211_find_sta_by_ifaddr() and release it when the resulting pointer is no longer needed. This problem was found while reviewing code to debug RCU warn from ath10k_wmi_tlv_parse_peer_stats_info().

ac_classify() expects a struct sk_buff* as its second argument, which is a member of struct tx_complete_data. priv happens to be a pointer to struct tx_complete_data, so passing it directly to ac_classify() leads to wrong behaviour and occasional panics. Since there is only one caller of wilc_wlan_txq_add_net_pkt and it already knows the type behind this pointer, and the structure is already in the header file, change the function signature to use the real type instead of void* in order to prevent confusion.

If the SKU_ID doesn't match, we don't increment the pointer and keep checking the same TLV over and over again. We need to increment the pointer in all situtations, namely if the TLV is not a SKU_ID, if the SKU_ID matched or if the SKU_ID didn't match. So we can increment the pointer already before checking for these conditions to solve the problem. Signed-off-by:

When the interface goes up, we have already loaded the PNVM during init, so we don't load it anymore. But we still need to set the PNVM values in the context so that the FW can load it again. Call set_pnvm when the PNVM is already loaded and change the trans_pcie implementation to accept a second call to set_pnvm when we have already allocated and, in this case, only set the values without allocating again.

When The driver in D3 and FW crash happens, trans->system_pm_mode is not reset to IWL_PLAT_PM_MODE_DISABLED which causes the driver not to send INIT conmmands and D3 resume fails.

Currently, for all devices and families, failing getting the temp from the fw is indicated in the log as ERR. This is too severe for two reasons: 1. The driver has a fall back - and schedules the next temp read immediately after failing to read temp from the fw. 2. The temp read implementation in the fw is different between HWs, and on older devices the flow is a-sync and may timeout. Reducing the print severity from ERR to WARN will allow to track the issue if it will appear many times, but not frighten users if it appears once. Signed-off-by:

Return value of the iwl_mvm_load_nvm_to_nic func is not analyzed. If load NVM to nic func fails and NVM is not loaded to fw properly, then fw may behave badly and lead to some strange issue. This commit will analyze return value and if load NVM to nic has failed, then the error code is sent to the previous func, which will trigger WRT log collection. iwl_fw_dbg_error_collect() func collects dump only if tri type is FW_DBG_TRIGGER_ALIVE_TIMEOUT. But when Load NVM to nic function fails trig_type is FW_DBG_TRIGGER_DRIVER. This commit also has code changes to collect dump when trig_type is FW_DBG_TRIGGER_DRIVER. Signed-off-by:

No need to pass the dbgfs_dir just to assign it to mvm. Assign to mvm and then call iwl_mvm_dbgfs_register. This is a preparation towards the addition of a delayed op_mode_start flow. This will allow to split the op_mode_start flow. Registration to debugfs must happen after we register to mac80211 and the registration to mac80211 will soon be delayed in certain cases. In order not to have to remember the debugfs_dir in a separate variable, just set it into the mvm structure so that it can be usable later. Declare mvm->debugfs_dir in the iwl_mvm structure even when IWLWIFI_DEBUGFS isn't enabled to simplify the source code. Signed-off-by:

All the actions that were taken after the registration can be taken before the registration to mac80211. This will help to defer part of the op_mode_mvm_start function to a later stage in case the device is not available. Signed-off-by:

RF Interference Mitigation is a new feature targeted to handle the problem of interference between DDR memory and WiFi. The role of the driver is to configure FW with the table holding a mapping between problematic channels/bands and the corresponding frequencies. This patch adds RFI infrastructure and adds two debugfs hooks: - send RFI configuration command (currently with a default table) which will reset feature in the FW - read the table, used by the FW (which can be a subset of the table that driver sent).

iwl_acpi_get_wifi_pkg() may return a valid pointer (meaning success), while `tbl_rev` is invalid (equel to 1). In this case, we will treat that as an error. Subsequent "users" of this "error code" may either check for nonzero (good; pointers are never zero) or negative (bad; pointers may be "positive") fix that by splitting the if statement.
