2019-05-01mt76: dma: add skb check for dummy pointerLorenzo Bianconi2-4/+7
Introduce skb check for dummy address in mt76_dma_tx_cleanup_idx. This is a preliminary patch to add support for new chipsets (e.g. 7615) Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
2019-05-01mt76: dma: introduce skb field in mt76_txwi_cacheLorenzo Bianconi3-1/+8
Introduce skb field in mt76_txwi_cache. Moreover add txwi_flags to mt76_driver_ops since new chipsets will release mt76_txwi_cache/skbs at tx completion instead of dma one. This is a preliminary patch to add mt7615 support Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
2019-05-01mt76: add skb pointer to mt76_tx_infoLorenzo Bianconi9-39/+43

2019-05-01mt76: usb: reduce locking in mt76u_tx_taskletLorenzo Bianconi1-8/+12
Similar to pci counterpart, reduce locking in mt76u_tx_tasklet since q->head is managed just in mt76u_tx_tasklet and q->queued is updated holding q->lock Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
2019-05-01mt76: move mac_work in mt76_devLorenzo Bianconi14-21/+20

2019-05-01mt76: store wcid tx rate info in one u32 reduce lockingFelix Fietkau5-18/+27
Signed-off-by: Felix Fietkau <[email protected]>
2019-05-01mt76: reduce locking in mt76_dma_tx_cleanupFelix Fietkau1-9/+17
q->tail can be safely updated without locking, because there is no concurrent access. If called from outside of the tasklet (for flushing), the tasklet is always disabled. q->queued can be safely read without locking, as long as the decrement happens within the locked section. This patch allows cleaning up tx packets outside of the section that holds the queue lock for improved performance Signed-off-by: Felix Fietkau <[email protected]>
2019-05-01mt76: use mac80211 txq schedulingFelix Fietkau5-61/+67
Performance improvement and preparation for adding airtime fairness support Signed-off-by: Felix Fietkau <[email protected]>
2019-05-01mt76: use readl/writel instead of ioread32/iowrite32Felix Fietkau4-16/+16
Switching to readl/writel is faster because it gets rid of an unnecessary wrapper with extra checks. Signed-off-by: Felix Fietkau <[email protected]>
2019-05-01mt76: fix tx power issuesFelix Fietkau5-13/+9
- tx power is stored in the channels after ieee80211_register_hw, so chan->orig_mpwr needs to be updated as well - for non-TSSI devices, mt76x2e needs to use a different target power value from the EEPROM - fix a rounding error in a few places (need to round up, not down) Signed-off-by: Felix Fietkau <[email protected]>
2019-05-01mt76: introduce mt76_free_device routineLorenzo Bianconi5-4/+11

2019-05-01mt76x02: make beacon slots bigger for USBStanislaw Gruszka4-37/+22
Since we sent PS buffered frames via beacon memory we need to make beacon slots bigger. That imply we will also need to decrease number of slots as beacon SRAM memory is limited to 8kB. Signed-off-by: Stanislaw Gruszka <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
2019-05-01mt76x02u: implement pre TBTT work for USBStanislaw Gruszka2-3/+35
Program beacons data and PS buffered frames on TBTT work for USB. We do not have MT_TXQ_PSD queue available via USB endpoints. The way we can send PS broadcast frames in timely manner before PS stations go sleep again is program them in beacon data area. Hardware do not modify those frames since TXWI is properly configured. mt76x02_mac_set_beacon() already handle this and free no longer used frames.
