2023-08-11wifi: mt76: mt7615: do not advertise 5 GHz on first phy of MT7615D (DBDC)Paul Fertser1-3/+3
[ Upstream commit 421033deb91521aa6a9255e495cb106741a52275 ] On DBDC devices the first (internal) phy is only capable of using 2.4 GHz band, and the 5 GHz band is exposed via a separate phy object, so avoid the false advertising.

2023-08-11mt76: mt7615: Fix fall-through warnings for ClangGustavo A. R. Silva1-1/+1
[ Upstream commit f12758f6f929dbcd37abdb1d91d245539eca48f8 ] In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning by replacing a /* fall through */ comment with the new pseudo-keyword macro fallthrough; instead of letting the code fall through to the next case. Notice that Clang doesn't recognize /* fall through */ comments as implicit fall-through markings. Link: https://github.com/KSPP/linux/issues/115 Signed-off-by: Gustavo A. R.

2020-09-24mt76: remove retry_q from struct mt76_txq and related codeFelix Fietkau1-3/+0
Since the switch to using AQL by default, mtxq->retry_q is never filled anymore Remove it to get rid of a few more unnecessary cycles in the tx path Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: convert from tx tasklet to tx worker threadFelix Fietkau5-9/+7
This improves performance by allowing the scheduler to move the tx scheduling work to idle CPUs. Since tx scheduling work is very latency sensitive and kept short via AQL, sched_set_fifo_low is used to keep worker priority above normal tasks Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7615: fix antenna selection for testmode tx_framesFelix Fietkau2-9/+1
Do not alter the tx/rx chain settings during channel setup, antennas are remapped by the testmode specific register writes already Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7615: fix MT_ANT_SWITCH_CON register definitionFelix Fietkau1-1/+1
This is used for testmode tx antenna selection Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: remove struct mt76_sw_queueFelix Fietkau5-25/+18
All members except for the struct mt76_queue pointer have been removed Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: rely on AQL for burst size limits on tx queueingFelix Fietkau3-3/+10
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>
2020-09-24mt76: remove swq from struct mt76_sw_queueFelix Fietkau1-2/+0
Since txq selection was moved to mac80211, it is no longer used Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: remove qid argument to drv->tx_complete_skbFelix Fietkau3-6/+2
It is not needed Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: sdio: fix use of q->head and q->tailFelix Fietkau1-3/+3
Their use is reversed compared to DMA. The order for DMA makes more sense, so let's use that Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7615: significantly reduce interrupt loadFelix Fietkau4-25/+20
On 7615 and newer, DMA completion only triggers unmap, but not free of queued skbs, since pointers to packets are queued internally. Because of that, there is no need to process the main data queue immediately on DMA completion. To improve performance, mask out the DMA data queue completion interrupt and process the queue only when we receive a txfree event. This brings the number of interrupts under load down to a small fraction. Signed-off-by: Felix Fietkau <nbd@nbd.name>
