2025-04-09wifi: rtw88: Don't set SUPPORTS_AMSDU_IN_AMPDU for RTL8814AUBitterblue Smith
RTL8814AU doesn't work well with SUPPORTS_AMSDU_IN_AMPDU. The RX speed is noticeably lower and the VHT RX statistics are strange. Typical values with SUPPORTS_AMSDU_IN_AMPDU: Reverse mode, remote host 192.168.0.1 is sending [ 5] local 192.168.0.50 port 60710 connected to 192.168.0.1 port 5201 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 74.6 MBytes 626 Mbits/sec [ 5] 1.00-2.00 sec 79.2 MBytes 665 Mbits/sec [ 5] 2.00-3.00 sec 84.9 MBytes 712 Mbits/sec [ 5] 3.00-4.00 sec 83.8 MBytes 703 Mbits/sec [ 5] 4.00-5.00 sec 85.9 MBytes 720 Mbits/sec [ 5] 5.00-6.00 sec 78.9 MBytes 662 Mbits/sec [ 5] 6.00-7.00 sec 81.2 MBytes 682 Mbits/sec [ 5] 7.00-8.00 sec 80.5 MBytes 675 Mbits/sec [ 5] 8.00-9.00 sec 79.4 MBytes 666 Mbits/sec [ 5] 9.00-10.00 sec 82.2 MBytes 689 Mbits/sec [ 5] 10.00-11.00 sec 82.0 MBytes 688 Mbits/sec [ 5] 11.00-12.00 sec 84.2 MBytes 707 Mbits/sec [ 5] 12.00-13.00 sec 71.0 MBytes 596 Mbits/sec [ 5] 13.00-14.00 sec 69.4 MBytes 582 Mbits/sec [ 5] 14.00-15.00 sec 80.2 MBytes 673 Mbits/sec [ 5] 15.00-16.00 sec 74.5 MBytes 625 Mbits/sec [Rx Counter]: * CCA (CCK, OFDM, Total) = (0, 2455, 2455) * False Alarm (CCK, OFDM, Total) = (0, 69, 69) * CCK cnt (ok, err) = (0, 0) * OFDM cnt (ok, err) = (1239, 2) * HT cnt (ok, err) = (0, 0) * VHT cnt (ok, err) = (21, 12109) The "VHT ok" number is not believable.

2025-04-09wifi: rtw88: Set AMPDU factor to hardware for RTL8814ABitterblue Smith
Tell the chip the maximum AMPDU size supported by the AP. This greatly improves the TX speed of RTL8814AU in the 2.4 GHz band. Before: ~90 Mbps. After: ~300 Mbps.

2025-01-12wifi: rtw88: Add support for LED blinkingBitterblue Smith
Register a struct led_classdev with the kernel's LED subsystem and create a throughput-based trigger for it. Then mac80211 makes the LED blink. Tested with Tenda U12 (RTL8812AU), Tenda U9 (RTL8811CU), TP-Link Archer T2U Nano (RTL8811AU), TP-Link Archer T3U Plus (RTL8812BU), Edimax EW-7611UCB (RTL8821AU), LM842 (RTL8822CU). Also tested with devices which don't have LEDs: the laptop's internal RTL8822CE and a no-name RTL8723DU.

2024-12-23wifi: rtw88: 8821a/8812a: Set ptct_efuse_size to 0Bitterblue Smith
Some RTL8812AU devices fail to probe: [ 12.478774] rtw_8812au 1-1.3:1.0: failed to dump efuse logical map [ 12.487712] rtw_8812au 1-1.3:1.0: failed to setup chip efuse info [ 12.487742] rtw_8812au 1-1.3:1.0: failed to setup chip information [ 12.491077] rtw_8812au: probe of 1-1.3:1.0 failed with error -22 It turns out these chips don't need to "protect" any bytes at the end of the efuse. The original value of 96 was copied from rtw8821c.c. No one reported any failures with RTL8821AU yet, but the vendor driver uses the same efuse reading code for both chips.
