2021-12-19mt76: mt7921s: fix cmd timeout in throughput testDeren Wu1-4/+4
During heavy loading throughtput test, the RX buffer (128) would be exhausted and some RX pkts dropped randomly. Increase buffer size from 128 to 512 (a safer length) to avoid tput degrade or cmd-timeout problem. Signed-off-by: Deren Wu <deren.wu@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2021-12-19mt76: mt7921s: fix the device cannot sleep deeply in suspendSean Wang1-1/+2
According to the MT7921S firmware, the cmd MCU_UNI_CMD_HIF_CTRL have to be last MCU command to execute in suspend handler and all data traffic have to be stopped before the cmd MCU_UNI_CMD_HIF_CTRL starts as well in order that mt7921 can successfully fall into the deep sleep mode. Where we reuse the flag MT76_STATE_SUSPEND and avoid creating another global flag to stop all of the traffic onto the SDIO bus.

2020-12-20mt76: sdio: remove wake logic in mt76s_process_tx_queueLorenzo Bianconi1-12/+3
Similar to mmio/usb code path, remove wake logic in mt76s_process_tx_queue routine. Starting from commit 90d494c99a99 ("mt76: improve tx queue stop/wake"), the wake queue logic on the sdio status path is no longer necessary since the hw queues are no longer stopped on the mt76 tx path.

2020-09-24mt76: rely on AQL for burst size limits on tx queueingFelix Fietkau1-1/+0
Now that AQL works well on all mt76 drivers, completely replace the arbitrary burst sizing and number of bursts logic for tx scheduling. For the short period of time in which AQL does not work well yet, limit each stations to 16 in-flight packets that have no estimated tx time. This should avoid filling the queue if a station connects and queues up a large number of packets before rate control information is available, especially with hardware rate control Signed-off-by: Felix Fietkau <nbd@nbd.name>
