* rtl8xxxu: fix RTL8723BU connection failure issue after warm rebootChris Chiu2019-10-221-0/+1
| | | | | | | | | | | | | | | | | | | The RTL8723BU has problems connecting to AP after each warm reboot. Sometimes it returns no scan result, and in most cases, it fails the authentication for unknown reason. However, it works totally fine after cold reboot. Compare the value of register SYS_CR and SYS_CLK_MAC_CLK_ENABLE for cold reboot and warm reboot, the registers imply that the MAC is already powered and thus some procedures are skipped during driver initialization. Double checked the vendor driver, it reads the SYS_CR and SYS_CLK_MAC_CLK_ENABLE also but doesn't skip any during initialization based on them. This commit only tells the RTL8723BU to do full initialization without checking MAC status.

* rtl8xxxu: add bluetooth co-existence support for single antennaChris Chiu2019-10-091-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | The RTL8723BU suffers the wifi disconnection problem while bluetooth device connected. While wifi is doing tx/rx, the bluetooth will scan without results. This is due to the wifi and bluetooth share the same single antenna for RF communication and they need to have a mechanism to collaborate. BT information is provided via the packet sent from co-processor to host (C2H). It contains the status of BT but the rtl8723bu_handle_c2h dose not really handle it. And there's no bluetooth coexistence mechanism to deal with it. This commit adds a workqueue to set the tdma configurations and coefficient table per the parsed bluetooth link status and given wifi connection state. The tdma/coef table comes from the vendor driver code of the RTL8192EU and RTL8723BU. However, this commit is only for single antenna scenario which RTL8192EU is default dual antenna. The rtl8xxxu_parse_rxdesc24 which invokes the handle_c2h is only for 8723b and 8192e so the mechanism is expected to work on both chips with single antenna. Note RTL8192EU dual antenna is not supported. Signed-off-by: Chris Chiu <chiu@endlessm.com> Signed-off-by: Jes Sorensen <Jes.Sorensen@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rtl8xxxu: Improve TX performance of RTL8723BU on rtl8xxxu driverChris Chiu2019-10-091-3/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have 3 laptops which connect the wifi by the same RTL8723BU. The PCI VID/PID of the wifi chip is 10EC:B720 which is supported. They have the same problem with the in-kernel rtl8xxxu driver, the iperf (as a client to an ethernet-connected server) gets ~1Mbps. Nevertheless, the signal strength is reported as around -40dBm, which is quite good. From the wireshark capture, the tx rate for each data and qos data packet is only 1Mbps. Compare to the Realtek driver at https://github.com/lwfinger/rtl8723bu, the same iperf test gets ~12Mbps or better. The signal strength is reported similarly around -40dBm. That's why we want to improve. After reading the source code of the rtl8xxxu driver and Realtek's, the major difference is that Realtek's driver has a watchdog which will keep monitoring the signal quality and updating the rate mask just like the rtl8xxxu_gen2_update_rate_mask() does if signal quality changes. And this kind of watchdog also exists in rtlwifi driver of some specific chips, ex rtl8192ee, rtl8188ee, rtl8723ae, rtl8821ae...etc. They have the same member function named dm_watchdog and will invoke the corresponding dm_refresh_rate_adaptive_mask to adjust the tx rate mask. With this commit, the tx rate of each data and qos data packet will be 39Mbps (MCS4) with the 0xF00000 as the tx rate mask. The 20th bit to 23th bit means MCS4 to MCS7. It means that the firmware still picks the lowest rate from the rate mask and explains why the tx rate of data and qos data is always lowest 1Mbps because the default rate mask passed is always 0xFFFFFFF ranges from the basic CCK rate, OFDM rate, and MCS rate. However, with Realtek's driver, the tx rate observed from wireshark under the same condition is almost 65Mbps or 72Mbps, which indicating that rtl8xxxu could still be further improved.

| | | | | | | | | | | | | | | In order to obtain retry count for a given rate we need to pass the full struct ieee80211_tx_info to the function setting the rate in he TX descriptor.
