      rtl8xxxu: fix RTL8723BU connection failure issue after warm reboot · 0eeb91ad
      Chris Chiu authored
      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 antenna · e542e66b
      Chris Chiu authored
      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.

      rtl8xxxu: Improve TX performance of RTL8723BU on rtl8xxxu driver · a9bb0b51
      Chris Chiu authored
      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.
