wifi: rtw88: 8821cu: Fix connection failure

2024-04-03T13:11:42Z

commit 605d7c0b05eecb985273b1647070497142c470d3 upstream. Clear bit 8 of REG_SYS_STATUS1 after MAC power on. Without this, some RTL8821CU and RTL8811CU cannot connect to any network: Feb 19 13:33:11 ideapad2 kernel: wlp3s0f3u2: send auth to 90:55:de:__:__:__ (try 1/3) Feb 19 13:33:13 ideapad2 kernel: wlp3s0f3u2: send auth to 90:55:de:__:__:__ (try 2/3) Feb 19 13:33:14 ideapad2 kernel: wlp3s0f3u2: send auth to 90:55:de:__:__:__ (try 3/3) Feb 19 13:33:15 ideapad2 kernel: wlp3s0f3u2: authentication with 90:55:de:__:__:__ timed out The RTL8822CU and RTL8822BU out-of-tree drivers do this as well, so do it for all three types of chips.

wifi: rtw88: Add missing VID/PIDs for 8811CU and 8821CU

2024-04-03T13:11:17Z

[ Upstream commit b8a62478f3b143592d1241de1a7f5f8629ad0f49 ] Add VID/PIDs that are known to be missing for this driver. Removed /* 8811CU */ and /* 8821CU */ as they are redundant since the file is specific to those chips. Removed /* TOTOLINK A650UA v3 */ as the manufacturer. It has a REALTEK VID so it may not be specific to this adapter. Verified and tested.

This version of the chip requires loading an extra AGC table right after the main one, but the extra table is being loaded at the wrong time, in rtw_chip_board_info_setup(). Move the extra AGC table loading to the right place, in rtw_phy_load_tables(). The rtw_chip_board_info_setup() can only do "software" things, and rtw_phy_load_tables() can really do IO.

wifi: rtw88: 8821cu: Fix firmware upload fail

2024-03-26T22:18:22Z

[ Upstream commit 41a7acb7dde8395f52a707bbba7712a898dfafb0 ] RTL8822CU, RTL8822BU, and RTL8821CU need an extra register write after reading and writing certain addresses. Without this, the firmware upload fails approximately more than 50% of the time. Tested with RTL8811CU (Tenda U9 V2.0) which is the same as RTL8821CU but without Bluetooth.

wifi: rtw89: fix misbehavior of TX beacon in concurrent mode

[ Upstream commit 756b31203d482d2dd1aa6c208978b0410dc7530f ] In concurrent mode, when STA interface is scanning, it causes AP interface TX beacon on wrong channel. We modified it to scan with the operating channel when one of the interfaces is already connected. Additionally, STA interface need to stop scan when AP interface is starting to avoid TX beacon on wrong channel. Finally, AP interface need to stop TX beacon when STA interface is scanning and switching to non-OP channel,This prevent other device to get beacons on wrong channel.
