Adaptive Frequency Hopping(AFH) is a method of transmitting radio signals by rapidly changing the carrier frequency among many distinct frequencies, which can avoid interference. Add this feature to update AFH parameter for 8822b. Signed-off-by:

The original mechanism may cause A2DP glitch during WiFi connecting AP. Because the original TDMA may decrease too much A2DP slot. This patch add a timer and variable to let the case A2DP + WL_Connecting performed more well. Signed-off-by:

Add counter to count BT info C2H command for debug usage. It could present the C2H channel situation. Fix BT IQK state decision condition for counting. The original condition is wrong, it would cause coexistence mechanism going to the wrong strategy. New format supports getting TDMA parameter from WL firmware, since coexistence needs current TDMA parameter to decide strategy. Remove unnecessary operations about scoreboard, it is not a must for current version. Signed-off-by:

The original stop_dm flag is shared with the wifi and coexistence mechanism internal usage, which represent two meanings, and makes developers hard to debug. Add a new flag manual_control for coexistence mechanism usage only. Signed-off-by:

Some register definition and bit definition were incorrect. e.g. REG_BT_COEX_V2 should be word alignment to meet the coding style. e.g. set REG_BT_TDMA_TIME[5:0]=0x5, But the original is to set REG_BT_TDMA_TIME[7:0]=0x5. This will cause unexpected hardware behavior. Signed-off-by:

The inner do { ... } while loop is completely useless, all it does is iterate over a switch-case statement, one bit at a time. This can easily be replaced by simple if (status & bit) { ... } tests for each bit. No functional change. Signed-off-by:Marek Vasut <marex@denx.de> Cc: Angus Ainslie <angus@akkea.ca> Cc: David S.

The interrupt handling of the RS911x is particularly heavy. For each RX packet, the card does three SDIO transactions, one to read interrupt status register, one to RX buffer length, one to read the RX packet(s). This translates to ~330 uS per one cycle of interrupt handler. In case there is more incoming traffic, this will be more. The drivers/mmc/core/sdio_irq.c has the following comment, quote "Just like traditional hard IRQ handlers, we expect SDIO IRQ handlers to be quick and to the point, so that the holding of the host lock does not cover too much work that doesn't require that lock to be held." The RS911x interrupt handler does not fit that. This patch therefore changes it such that the entire IRQ handler is moved to the RX thread instead, and the interrupt handler only wakes the RX thread. This is OK, because the interrupt handler only does things which can also be done in the RX thread, that is, it checks for firmware loading error(s), it checks buffer status, it checks whether a packet arrived and if so, reads out the packet and passes it to network stack. Moreover, this change permits removal of a code which allocated an skbuff only to get 4-byte-aligned buffer, read up to 8kiB of data into the skbuff, queue this skbuff into local private queue, then in RX thread, this buffer is dequeued, the data in the skbuff as passed to the RSI driver core, and the skbuff is deallocated. All this is replaced by directly calling the RSI driver core with local buffer. Signed-off-by:

The problem is now that _mwifiex_fw_dpc() calls mwifiex_free_adapter() in case firmware initialization fails. That ends up calling mwifiex_cleanup_pcie(). Note that all those calls are still running on the workqueue. So when mwifiex_cleanup_pcie() now calls cancel_work_sync(), it's really waiting on itself to complete, causing a deadlock. This commit fixes the deadlock by skipping cancel_work_sync() on a reset failure path. After this commit, when reset fails, the following output is expected to be shown: kernel: mwifiex_pcie 0000:03:00.0: info: _mwifiex_fw_dpc: unregister device kernel: mwifiex: Failed to bring up adapter: -5 kernel: mwifiex_pcie 0000:03:00.0: reinit failed: -5 To reproduce this issue, for example, try putting the root port of wifi into D3 (replace "00:1d.3" with your setup). # put into D3 (root port) sudo setpci -v -s 00:1d.3 CAP_PM+4.b=0b Cc: Maximilian Luz <luzmaximilian@gmail.com> Signed-off-by:Tsuchiya Yuto <kitakar@gmail.com> Signed-off-by:

The functions mwifiex_shutdown_sw() and mwifiex_reinit_sw() can be used for more general purposes than the PCIe function level reset. Also, these are even not PCIe-specific. So, let's update the comments at the top of each function accordingly. Signed-off-by:

When a PCIe function level reset (FLR) is performed but without fw reset for some reasons (e.g., on Microsoft Surface devices, fw reset requires other quirks), it fails to reset wifi properly.

rt2800 only gives you survey for current channel. Survey-based ACS algorithms are failing to perform their job when working with rt2800. Make rt2800 save survey for every channel visited and be able to give away that information. There is a bug registered https://dev.archive.openwrt.org/ticket/19081 and this patch solves the issue.

halbtc_send_bt_mp_operation() uses in_interrupt() to determine if it is safe to invoke wait_for_completion(). The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. Aside of that in_interrupt() is not correct as it does not catch preempt disabled regions which neither can sleep. halbtc_send_bt_mp_operation() is called from: rtl_watchdog_wq_callback() rtl_btc_periodical() halbtc_get() case BTC_GET_U4_BT_PATCH_VER: halbtc_get_bt_patch_version() which is preemtible context. rtl_c2h_content_parsing() btc_ops->btc_btinfo_notify() rtl_btc_btinfo_notify() exhalbtc_bt_info_notify() ex_btc8723b1ant_bt_info_notify() ex_btc8821a1ant_bt_info_notify() ex_btc8821a2ant_bt_info_notify() btcoexist->btc_set_bt_reg() halbtc_set_bt_reg() rtl_c2h_content_parsing() is in turn called from: rtl_c2hcmd_wq_callback() rtl_c2hcmd_launcher() which is preemptible context and from: _rtl_pci_rx_interrupt rtl_c2hcmd_enqueue() which is obviously not preemptible but limited to C2H_BT_MP commands which does invoke rtl_c2h_content_parsing(). Aside of that it can be reached from: halbtc_get() case BTC_GET_U4_SUPPORTED_FEATURE: halbtc_get_bt_coex_supported_feature() case BTC_GET_U4_BT_FORBIDDEN_SLOT_VAL: halbtc_get_bt_forbidden_slot_val() case BTC_GET_U4_BT_DEVICE_INFO: halbtc_get_bt_device_info() case BTC_GET_U4_SUPPORTED_VERSION: halbtc_get_bt_coex_supported_version() case BTC_GET_U4_SUPPORTED_FEATURE: halbtc_get_bt_coex_supported_feature() btcoexist->btc_get_bt_afh_map_from_bt() halbtc_get_bt_afh_map_from_bt() btcoexist->btc_get_ble_scan_para_from_bt() halbtc_get_ble_scan_para_from_bt() btcoexist->btc_get_ble_scan_type_from_bt() halbtc_get_ble_scan_type_from_bt() btcoexist->btc_get_ant_det_val_from_bt() halbtc_get_ant_det_val_from_bt() btcoexist->btc_get_bt_coex_supported_version() halbtc_get_bt_coex_supported_version() btcoexist->btc_get_bt_coex_supported_feature() halbtc_get_bt_coex_supported_feature() None of these have a caller.
