2020-12-04mt76: move tx hw data queues in mt76_phyLorenzo Bianconi1-5/+2
Move hw data queues in mt76_phy from mt76_dev since mt7915 supports per phy hw queues in dbdc mode Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-12-04mt76: introduce mt76_init_mcu_queue utility routineLorenzo Bianconi1-9/+7
Introduce mt76_init_mcu_queue utility routine in order to allocate dedicate q_mcu pointers for mcu hw queues. This is a preliminary patch to move data queues in mt76_phy and add dbdc support to mt7915 driver Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-12-04mt76: move mt76_init_tx_queue in common codeLorenzo Bianconi1-0/+21
Move mt76_init_tx_queue in mac80211.c since it is shared by all drivers. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-12-04mt76: add back the SUPPORTS_REORDERING_BUFFER flagFelix Fietkau1-0/+1
It was accidentally dropped while adding multiple wiphy support Fixes fast-rx support and avoids handling reordering in both mac80211 and the driver Cc: stable@vger.kernel.org Fixes: c89d36254155 ("mt76: add function for allocating an extra wiphy") Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-12-04mt76: do not set NEEDS_UNIQUE_STA_ADDR for 7615 and 7915Felix Fietkau1-1/+0
The newer chipsets can deal with the same STA on multiple interfaces Preparation for supporting more station interfaces Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-12-04mt76: use ieee80211_rx_list to pass frames to the network stack as a batchFelix Fietkau1-2/+13
Improves icache footprint Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7663s: introduce sdio tx aggregationLorenzo Bianconi1-4/+1
Introduce sdio tx aggregation to reduce bus transaction ands improve tx throughput. For the moment the skb are copied in a dedicated buffer since mmc APIs do not support sg table for zero-copy. Since skb data are already copied in xmit_buff[], avoid linearization in ma80211 layer. Relying on tx aggregation, we improve tx tpt of ~65%.

2020-09-24mt76: remove retry_q from struct mt76_txq and related codeFelix Fietkau1-19/+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: move txwi handling code to dma.c, since it is mmio specificFelix Fietkau1-2/+0
This way we can make some functions static Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: convert from tx tasklet to tx worker threadFelix Fietkau1-3/+11
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: remove struct mt76_sw_queueFelix Fietkau1-1/+1
All members except for the struct mt76_queue pointer have been removed Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-07-21mt76: mt7615: wake device in mt7615_update_channel before access regmapLorenzo Bianconi1-2/+2
Introduce mt7615_update_survey utility routine in order to compute survey stats without waking up the device since it runs holding mt76 lock. Run mt7615_pm_wake directly in mt7615_update_channel since it can run with mt76.mutex held if called by mac80211 Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-07-21mt76: move mt76 workqueue in common codeLorenzo Bianconi1-1/+12

2020-07-21mt76: add API for testmode supportFelix Fietkau1-0/+7
This can be used for calibration in the manufacturing process. It supports sending a configurable number of packets with a specific rate and configurable tx power levels / antenna settings. It also supports receiving packets and showing some statistics, including packet counters and detailed RSSI information. It will only be compiled in if CONFIG_NL80211_TESTMODE is enabled Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-07-21mt76: add U-APSD support on AP sideLorenzo Bianconi1-1/+3
Introduce U-APSD support in mt76 driver for AP interface Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-07-21mt76: allow more channels, allowed in ETSI domainMarkus Theil1-0/+3
While looking at the ETSI regulatory domain definitions and a patch, which allows more channels for ath10k, I also checked the channels allowed for mt76. ETSI regulations would possibly allow to add channels 32, 68, 96, 144, 169 and 173. IEEE 802.11-2016 defines no operating class for channels 32, 68 and 96. This leaves us channels 144, 169 and 173, which are included in this patch. I tested 169 and 173 with a mt76 based USB dongle (AVM AC 860) and they worked fine. If I saw that right, these channels are also covered by register definitions inside the driver. Channel 144 should also work, but gets disabled by the kernel as of now.

2020-05-12mt76: fix A-MPDU density handlingFelix Fietkau1-1/+0
The hardware requirements for A-MPDU density are entirely on the tx side, not the rx side. Because of that, the IE value should stay at 0 and the minimum value should instead be enforced in WTBL/TXWI MT7615 has no restrictions here Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: remove PS_NULLFUNC_STACK capabilityLorenzo Bianconi1-1/+0

2020-02-14mt76: Introduce mt76_mcu data structureLorenzo Bianconi1-0/+4
Introduce mt76_mcu data structure to contain common fields between mt76u_mcu and mt76e_mcu. Initialize mcu common fields in mt76_alloc_device().

2020-02-14mt76: introduce struct mt76_phyFelix Fietkau1-0/+5
This is preparation for supporting multiple wiphys per device to support the concurrent dual-band feature of MT7615D On the first wiphy, hw->priv will point to struct mt76_dev, which contains a struct mt76_phy at the start. For the secondary wiphy, hw->priv will point to a mt76_phy encapsulated in a driver specific struct To simplify access to struct mt76_phy members from drivers, the driver specific device struct is changed to add a union of struct mt76_dev and struct mt76_phy as the first element Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-12-18mt76: fix LED link time failureArnd Bergmann1-1/+2
