wifi: rt2x00: remove unused delayed work data from link description

2024-05-20T05:05:52+00:00

Remove unused 'agc_work' and 'vco_work' members of 'struct link'. This follows commit d96324703ffa ("rt2x00: merge agc and vco works with link tuner") where AGC and VCO calibration code was completely redesigned. Compile tested only.

wifi: rt2x00: make watchdog param per device

wifi: rt2x00: introduce DMA busy check watchdog for rt2800

2023-11-08T18:14:10+00:00

When I tried to fix the watchdog of rt2800, I found that sometimes the watchdog can not reset the hung device. This is because the queue is not completely stuck, it just becomes very slow. The MTK vendor driver for the new chip MT7603/MT7612 has a DMA busy watchdog to detect device hangs by checking DMA busy status. This watchdog implementation is something similar to it. To reduce unnecessary reset, we can check the INT_SOURCE_CSR register together as I found that when the radio hung, the RX/TX coherent interrupt will always stuck at triggered state. The 'watchdog' module parameter has been extended to control all watchdogs(0=disabled, 1=hang watchdog, 2=DMA watchdog, 3=both). This new watchdog function is a slight schedule and it won't affect the transmission speed. So we can turn on it by default. Due to the INT_SOURCE_CSR register is invalid on rt2800 USB NICs, the DMA busy watchdog will be automatically disabled for them. Tested on MT7620 and RT5350.

wifi: rt2x00: rework MT7620 PA/LNA RF calibration

2023-10-25T09:06:16+00:00

1. Move MT7620 PA/LNA calibration code to dedicated functions. 2. For external PA/LNA devices, restore RF and BBP registers before R-Calibration. 3. Do Rx DCOC calibration again before RXIQ calibration. 4. Add some missing LNA related registers' initialization.

wifi: rt2x00: Fix "Error - Attempt to send packet over invalid queue 2"

2022-09-19T10:08:57+00:00

Even though ieee80211_hw.queues is set to 2, the ralink rt2x00 driver is seeing tx skbs submitted to it with the queue-id set to 2 / set to IEEE80211_AC_BE on a rt2500 card when associating with an access-point. This causes rt2x00queue_get_tx_queue() to return NULL and the following error to be logged: "ieee80211 phy0: rt2x00mac_tx: Error - Attempt to send packet over invalid queue 2", after which association with the AP fails. This patch works around this by mapping QID_AC_BE and QID_AC_BK to QID_AC_VI when there are only 2 tx_queues.

rt2x00: save survey for every channel visited

2020-11-07T15:53:32+00:00

rt2800 only gives you survey for current channel. Survey-based ACS algorithms are failing to perform their job when working with rt2800. Make rt2800 save survey for every channel visited and be able to give away that information. There is a bug registered https://dev.archive.openwrt.org/ticket/19081 and this patch solves the issue.
