If the chip can have an LED, register a struct led_classdev and enable hardware-controlled blinking. When the chip is not transmitting or receiving anything the LED is off. Otherwise the LED will blink faster or slower according to the throughput. The LED can be controlled from userspace by writing 0, 1, or 2 to /sys/class/leds/rtl8xxxu-usbX-Y/brightness: 0 - solid off. 1 - solid on. 2 - hardware-controlled blinking. In this patch none of the chips advertise having an LED. That will be added in the next patches. Signed-off-by:

Macros prefixed with CONFIG_ are intended to be defined only by Kconfig scripts. Here we remove the prefix from the CONFIG_AUTO_READ_MODE define to avoid confusion when reading the code. This causes no change to functionality. Signed-off-by:

Previously, all supported chips had two RF paths. Therefore, these codes used static number for TX power setting. Now, we are planning to support a new chip which has only one RF path. So, we refine the setting codes to refer to chip's RF path number at runtime. Signed-off-by:

For a packet with 1SS rate, it can also transmit via 2 antenna, called 2T mode. For 2T TX power offset, mask should be 2T as well. Fortunately, the mask of 2T and 1T are the same, so it can still work well without this fix. Signed-off-by:

In path of setting channel and setting TX power, the rtw89_chan instance to be used is controlled by top and passed down. The set_tx_shape_dfir() is in path of setting TX power, so it should use the passed rtw89_chan instead of querying it itself. Otherwise, it might encounter mismatch between parameters if multi-channel. For example, rtw89_8852ce 0000:04:00.0: set tx shape dfir by unknown ch: 155 on 2GHz Signed-off-by:

New firmware type NORMAL_CE is introduced to support P2P-PS and hardware scan, but no LPS-PG mode. After this patch, old firmware with NORMAL type can still work well. The use of this new type is the same as before, so we add new type to avoid taking wrong firmware. Then, driver log can also give clear information about this change: rtw89_8852be 0000:03:00.0: Firmware version 0.29.26.0, cmd version 0, type 5 rtw89_8852be 0000:03:00.0: Firmware version 0.29.26.0, cmd version 0, type 3 Signed-off-by:

Due to firmware size limit of 8852b, LPS-PG mode isn't supported after 0.29.26.0, and then we have more space to support other features, such as P2P-PS, hardware scan and so on. Signed-off-by:

Driver can prepare pkt_list for firmware that only uses them to send out the packets in specific situations. To understand the usage of current status, and to check if there is leakage problem, dump bitmap and the indices used by certain function. An example looks like: map: ... pkt_ofld: 3f 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ... [SCAN 0]: 3 [SCAN 1]: 4 [SCAN 3]: 5 VIF [0] xx:xx:xx:xx:xx:xx ... pkt_ofld[GENERAL]: 0 1 2 Signed-off-by: -

To debug channel concurrency more centrally, we add a new debug flag, RTW89_DBG_CHAN, for channel related things, especially channel concurrency. Then, we change MCC (multi-channel concurrency) C2H (chip to host packets) debug flag to it. Besides, refine debug logs to show TSF in u64 directly. Signed-off-by:

RXI300 is a HW design to maintain stuffs across BUS, e.g. AXI, AHB, APB. It will feedback an error when host does an invalid BUS operation. For example, * BUS master request without power/clock on. * host reads/writes/accesses an invalid address. They might lead to problems such as BUS timeout, platform hang, etc. So, once if RXI300 feedback an error, it notifies that driver need a L2 SER (system error recovery) to reset things. Previously, driver did not parse the error scenario for RXI300. We add it and assign a corresponding error code which will make SER flow do L2 reset. Signed-off-by:

Only 8852C chip has valid pages on RTW89_DBG_SEL_MAC_30. To other chips, this section is an address hole. It will lead to crash if trying to access this section on chips except for 8852C. So, we avoid that. Signed-off-by:

Originally, rtw89_mac_port_tsf_sync() contains randomization logic internally. However, not all situation, we need the randomization. So, split out the generic part from it. And, make the full logic of original one contained in rtw89_mac_port_tsf_sync_rand(). It will still be used by its original caller as before. Then, the generic one will be used in MCC (multi-channel concurrency) management flow. MCC will implement its logic to decide the offset for TSF sync. Signed-off-by:

Strictly speaking, the unit of the offset should be TU instead of ms. So, correct it and the macro for calculation. Then, to make the macro generic, the factor n is moved outside. Signed-off-by:

The origin code will enable TDMA WL:BT = 50:50 to prevent Wi-Fi throughput suddenly drop to 0 in the moment while A2DP pause. And this protection just a short moment, and will turn to Bluetooth idle case when A2DP turn into sniff mode. But the raspberryPI simulated A2DP device will not turn into sniff mode. So the protection will bring the throughput drop. Signed-off-by:

The Marvell SD8978 (aka NXP IW416) uses identical registers as SD8987, so reuse the existing mwifiex_reg_sd8987 definition. Note that mwifiex_reg_sd8977 and mwifiex_reg_sd8997 are likewise identical, save for the fw_dump_ctrl register: They define it as 0xf0 whereas mwifiex_reg_sd8987 defines it as 0xf9. I've verified that 0xf9 is the correct value on SD8978. NXP's out-of-tree driver uses 0xf9 for all of them, so there's a chance that 0xf0 is not correct in the mwifiex_reg_sd8977 and mwifiex_reg_sd8997 definitions. I cannot test that for lack of hardware, hence am leaving it as is. NXP has only released a firmware which runs Bluetooth over UART. Perhaps Bluetooth over SDIO is unsupported by this chipset. Consequently, only an "sdiouart" firmware image is referenced, not an alternative "sdsd" image. Signed-off-by:
