This parameter is replaced by a boolean in the main structure used by all routines. It still cannot be changed dynamically, but it is easier to document. The following routines are restored: halbtc8723b1ant_bt_auto_report() halbtc8723b1ant_set_bt_auto_report() halbtc8723b1ant_action_wifi_only() halbtc8723b1ant_monitor_bt_enable_disable() Signed-off-by: Larry Finger Cc: Yan-Hsuan Chuang Cc: Pkshih Cc: Birming Chiu Cc: Shaofu Cc: Steven Ting Signed-off-by: Kalle Valo --- diff --git a/drivers/net/wireless/realtek/rtlwifi/btcoexist/halbtc8723b1ant.c b/drivers/net/wireless/realtek/rtlwifi/btcoexist/halbtc8723b1ant.c index 2003c8c51dcc..f23c9e3fbda1 100644 --- a/drivers/net/wireless/realtek/rtlwifi/btcoexist/halbtc8723b1ant.c +++ b/drivers/net/wireless/realtek/rtlwifi/btcoexist/halbtc8723b1ant.c @@ -333,6 +333,35 @@ static void halbtc8723b1ant_update_bt_link_info(struct btc_coexist *btcoexist) bt_link_info->hid_only = false; } +static void halbtc8723b1ant_set_bt_auto_report(struct btc_coexist *btcoexist, + bool enable_auto_report) +{ + u8 h2c_parameter[1] = {0}; + + h2c_parameter[0] = 0; + + if (enable_auto_report) + h2c_parameter[0] |= BIT(0); + + btcoexist->btc_fill_h2c(btcoexist, 0x68, 1, h2c_parameter); +} + +static void halbtc8723b1ant_bt_auto_report(struct btc_coexist *btcoexist, + bool force_exec, + bool enable_auto_report) +{ + coex_dm->cur_bt_auto_report = enable_auto_report; + + if (!force_exec) { + if (coex_dm->pre_bt_auto_report == coex_dm->cur_bt_auto_report) + return; + } + halbtc8723b1ant_set_bt_auto_report(btcoexist, + coex_dm->cur_bt_auto_report); + + coex_dm->pre_bt_auto_report = coex_dm->cur_bt_auto_report; +} + static void btc8723b1ant_set_sw_pen_tx_rate_adapt(struct btc_coexist *btcoexist, bool low_penalty_ra) { @@ -1099,6 +1128,57 @@ static void halbtc8723b1ant_power_save_state(struct btc_coexist *btcoexist, } } +static void halbtc8723b1ant_action_wifi_only(struct btc_coexist *btcoexist) +{ + halbtc8723b1ant_coex_table_with_type(btcoexist, FORCE_EXEC, 0); + halbtc8723b1ant_ps_tdma(btcoexist, FORCE_EXEC, false, 8); + halbtc8723b1ant_set_ant_path(btcoexist, false, false, BTC_ANT_PATH_PTA); +} + +/* check if BT is disabled */ +static void halbtc8723b1ant_monitor_bt_enable_disable(struct btc_coexist + *btcoexist) +{ + struct rtl_priv *rtlpriv = btcoexist->adapter; + static u32 bt_disable_cnt; + bool bt_active = true, bt_disabled; + + if (coex_sta->high_priority_tx == 0 && + coex_sta->high_priority_rx == 0 && coex_sta->low_priority_tx == 0 && + coex_sta->low_priority_rx == 0) + bt_active = false; + if (coex_sta->high_priority_tx == 0xffff && + coex_sta->high_priority_rx == 0xffff && + coex_sta->low_priority_tx == 0xffff && + coex_sta->low_priority_rx == 0xffff) + bt_active = false; + if (bt_active) { + bt_disable_cnt = 0; + bt_disabled = false; + } else { + bt_disable_cnt++; + if (bt_disable_cnt >= 2) + bt_disabled = true; + } + if (coex_sta->bt_disabled != bt_disabled) { + RT_TRACE(rtlpriv, COMP_BT_COEXIST, DBG_LOUD, + "[BTCoex], BT is from %s to %s!!\n", + (coex_sta->bt_disabled ?
