2021-04-21mt76: dma: add the capability to define a custom rx napi poll routineLorenzo Bianconi1-1/+1
Add the capability to define a custom rx napi callback for each driver. This is a preliminary patch to properly support runtime-pm on rx side Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2021-04-13mt76: report Rx timestampRyder Lee3-15/+21
Frame reception timestamp (low 32-bits) that indicates the value of the local TSF timer value at the time the first bit of the MAC header in the received frame (PPDU unit) arriving at the MAC. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2021-04-12mt76: use threaded NAPIFelix Fietkau1-1/+1
With threaded NAPI, the rx handler function is no longer bound to the CPU that fired the interrupt, which significantly helps to spread the workload over multiple CPUs, especially when multiple devices are using threaded NAPI at the same time. Exclude the tx handler from threaded NAPI by using a separate dummy netdev. The work is small and short-lived enough that it makes more sense to run it in softirq instead of creating a dedicated thread Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-09-24mt76: Use fallthrough pseudo-keywordGustavo A. R. Silva2-3/+3
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

2020-09-24mt76: remove retry_q from struct mt76_txq and related codeFelix Fietkau1-2/+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 Fietkau2-4/+3
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: mt7603: tune tx ring sizeFelix Fietkau2-2/+4
Stop relying on global tx ring size, reduce size for PS/mgmt queue Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: remove struct mt76_sw_queueFelix Fietkau4-17/+15
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 Fietkau1-1/+1
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 Fietkau1-1/+0
Since txq selection was moved to mac80211, it is no longer used Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-09-24mt76: mt7603: check for single-stream EEPROM configurationFelix Fietkau3-7/+18

2020-09-24mt76: move mt76_check_agg_ssn to driver tx_prepare callsFelix Fietkau1-0/+2
mt7615 and newer drivers do not need this, since they use sequence number offload Moving this code also reduces the number of callsites to make it easier to review Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: set interrupt mask register to 0 before requesting irqFelix Fietkau2-0/+4

2020-07-21mt76: vif_mask to struct mt76_phyFelix Fietkau2-5/+3
All drivers use this in pretty much the same way. Moving it to core helps with some checks for the upcoming testmode support Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-07-21mt76: add missing lock configuring coverage classLorenzo Bianconi1-0/+2
Coverage class callback can potentially run in parallel with other routines (e.g. mt7615_set_channel) that configures timing registers. Run coverage class callback holding mt76 mutex Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
