In the new API implementation the driver does not keep the internal and external debug configurations in separate structs so the last configuration that is loaded overrides the previous ones (this is true only in some of the TLVs e.g. the buffer allocation TLV). Load the external configuration after the internal is loaded so that user configuration will override the default coming with the FW. Signed-off-by:

The use of u8 and __le16 in this struct assumes that it's going to be packed to byte alignment. C doesn't guarantee that, so we should mark this __packed. Fixes: cc20a713 ("rtw88: use struct rtw_fw_hdr to access firmware header") Cc: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by:

With shallow buffer size, certain BT devices have active A2DP flow control to fill buffer frequently. If the slot is not at BT side, data can't be sent successfully to BT devices, and will cause audio glitch. To resolve this issue, this commit splits TUs into 4-slots instead of 2-slot for all of the A2DP related coexistence strategies. That makes BT have higher opportunity to fill the A2DP buffer in time, and the audio quality could be more stable and smooth. Signed-off-by:

Add support for NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 feature. According to the "Hardware crypto acceleration" documentation section, when set_key() is called with %DISABLE_KEY command, for outgoing frames, we flush out frames in the queues with the old key; for incoming frames, no frames will be passed to mac80211 decrypted with the old key due to rtw_sec_clear_cam().

In this step, the read/write routines for the descriptors are converted to use __le32 quantities, thus a lot of casts can be removed. Callback routines still use the 8-bit arrays, but these are changed within the specified routine. Signed-off-by:

Larry Finger authored
As a first step in the conversion, the macros that set the RX and TX descriptors are converted to static inline routines, and the names are changed from upper to lower case. To minimize the changes in a given step, the input descriptor information is left as as a byte array (u8 *), even though it should be a little-endian word array (__le32 *). That will be changed in the next patch. Several places where checkpatch.pl complains about a space after a cast and other warnings are fixed. Signed-off-by:

Larry Finger authored
This driver uses a set of local macros to manipulate the RX and TX descriptors, which are all little-endian quantities. These macros are replaced by the bitfield macros le32p_replace_bits() and le32_get_bits(). In several places, the macros operated on an entire 32-bit word. In these cases, a direct read or replacement is used. Signed-off-by:

We set WL1271_FLAG_IRQ_RUNNING in the beginning of wlcore_irq(), but clear it before interrupt handling is done in wlcore_irq_locked(). Let's move the clearing to the end of wlcore_irq() where it gets set, and remove the old comments about hardirq. That's no longer the case as we're using request_threaded_irq(). Note that the WL1271_FLAG_IRQ_RUNNING should never race between the interrupt handler and wlcore_runtime_resume() as because of autosuspend timeout we cannot enter idle between wlcore_irq_locked() and the end of wlcore_irq().

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:

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. Signed-off-by:
