2020-12-04mt76: move tx hw data queues in mt76_phyLorenzo Bianconi
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 Bianconi
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 Bianconi
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 Fietkau
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 Fietkau
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 Fietkau
Improves icache footprint Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7663s: introduce sdio tx aggregationLorenzo Bianconi
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 Fietkau
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 Fietkau
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 Fietkau
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 Fietkau
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 Bianconi
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 Bianconi

2020-07-21mt76: add API for testmode supportFelix Fietkau
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 Bianconi
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 Theil
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 Fietkau
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 Bianconi
remove IEEE80211_HW_PS_NULLFUNC_STACK capability from mt76_phy_init routine since 802.11 ps is not currently supported by any devices and it will conflict with mt7663 ps fw support Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: Introduce mt76_mcu data structureLorenzo Bianconi
Introduce mt76_mcu data structure to contain common fields between mt76u_mcu and mt76e_mcu. Initialize mcu common fields in mt76_alloc_device(). Rely on mt76_mcu in mt76_mcu_rx_event and in mt76_mcu_get_response in order to reuse them in usb code Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-02-14mt76: fix rounding issues on converting per-chain and combined txpowerFelix Fietkau
Unify code converting between the different txpower values. Always add/remove the combined txpower delta before dividing half-dB values. Also fix the combined txpower delta values. The correct half-dB delta for 3 chains is 9, not 8. Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-02-14mt76: introduce struct mt76_phyFelix Fietkau
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 Bergmann
