2020-12-30	mt76: fix memory leak if device probing fails	Lorenzo Bianconi	1	-2/+3
	[ Upstream commit bc348defcc6eceeb4f7784bf9a263ddb72fd3fb4 ] Run mt76_free_device instead of ieee80211_free_hw if device probing fails in order to remove the already allocated mt76 workqueue Fixes: a86f1d01f5ce5 ("mt76: move mt76 workqueue in common code") Fixes: f1d962369d568 ("mt76: mt7915: implement HE per-rate tx power support") Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Sasha Levin <sashal@kernel.org>
2020-09-24	mt76: mt7915: significantly reduce interrupt load	Felix Fietkau	1	-3/+3
	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>
2020-09-24	mt76: mt7915: add Tx A-MSDU offloading support	Ryder Lee	1	-1/+2
	This disables the software A-MSDU aggregation in mac80211 and enables hardware offloading Suggested-by: Yiwei Chung <yiwei.chung@mediatek.com> Suggested-by: YF Luo <yf.luo@mediatek.com> Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Shayne Chen <shayne.chen@mediatek.com> Co-developed-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24	mt76: mt7915: clean up and fix interrupt masking in the irq handler	Felix Fietkau	1	-14/+11
	Only clear unmasked interrupts. If an interrupt is temporarily masked, its pending events need to be processed later, even if another interrupt happened in the mean time. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24	mt76: set interrupt mask register to 0 before requesting irq	Felix Fietkau	1	-0/+2
	Avoids spurious interrupts in case the hardware was running already Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-07-21	mt76: mt7915: overwrite qid for non-bufferable mgmt frames	Ryder Lee	1	-1/+1
	Overwrite hw queue id for non-bufferable management frames if the hw/fw support always txq (altxq) in order to be in sync with mac txwi code Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12	mt76: mt7915: implement HE per-rate tx power support	Ryder Lee	1	-0/+25
	Use firmware support for applying per-rate limit and power offsets. This can support all HE RU types.

2020-05-12	mt76: add mac80211 driver for MT7915 PCIe-based chipsets	Ryder Lee	1	-0/+166
	Add support for the MediaTek latest generation IEEE 802.11ax 4x4 device MT7915E, which supports concurrent dual-band operation at both 5GHz and 2.4GHz. Note that this patch just add basic part and will add more HE capabilities support in the further patches. The driver supports AP, Station, Mesh and monitor mode.
