2020-09-24mt76: Convert to DEFINE_SHOW_ATTRIBUTEQinglang Miao
Use DEFINE_SHOW_ATTRIBUTE macro to simplify the code. Signed-off-by: Qinglang Miao <miaoqinglang@huawei.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: Use fallthrough pseudo-keywordGustavo A. R. Silva
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. [1] https://www.kernel.org/doc/html/v5.7/process/deprecated.html?highlight=fallthrough#implicit-switch-case-fall-through Signed-off-by: Gustavo A. R. Silva <gustavoars@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
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: 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: mt7603: tune tx ring sizeFelix Fietkau
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 Fietkau
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 Fietkau
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 Fietkau
Since txq selection was moved to mac80211, it is no longer used Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: remove qid argument to drv->tx_complete_skbFelix Fietkau
It is not needed Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7603: check for single-stream EEPROM configurationFelix Fietkau
Some devices using MT7628 or MT7603 have only one antenna chain connected. Detect these using the EEPROM rx/tx path settings Reported-by: Qin Wei <me@vonger.cn> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: move mt76_check_agg_ssn to driver tx_prepare callsFelix Fietkau
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 Fietkau
Avoids spurious interrupts in case the hardware was running already Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-07-21mt76: vif_mask to struct mt76_phyFelix Fietkau
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 Bianconi
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>

2020-05-28mt76: fix per-driver wcid range checks after wcid array size bumpFelix Fietkau
All drivers before MT7915 have a limit of 128 WCID entries. Stop relying on ARRAY_SIZE(dev->mt76.wcid), since it no longer reflects that limit. Fixes: 49e649c3e0a6 ("mt76: adjust wcid size to support new 802.11ax generation") Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-05-12mt76: mt7603: remove duplicate error messageDejin Zheng
it will print an error message by itself when devm_platform_ioremap_resource() goes wrong. so remove the duplicate error message. Signed-off-by: Dejin Zheng <zhengdejin5@gmail.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: mt7603: fix tx status rate index calculationFelix Fietkau
A switch from one rate index to the next only happens when tx count from the current slot is greater than MT7615_RATE_RETRY, which is 1 has to be subtracted from count, instead of added to it. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: mt7603: never use an 802.11b CF-End rate on 5GHzFelix Fietkau
Sometimes mt7615_mac_set_timing gets called while the slot time is still configured to 20. Ensure that in this case it always uses the OFDM CFend rate. Signed-off-by: Felix Fietkau <nbd@nbd.name>
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: add rx queues info to mt76 debugfsLorenzo Bianconi
Introduce rx-queues debugfs node in order to dump rx queues status. This would be useful for mcu fw debugging Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: mt7603: disable merge of OTP ROM data by defaultFelix Fietkau
The reference driver does not seem to enable it by default, only under certain conditions, e.g. when a .bin file is loaded. Make it opt-in via a device tree property for now, in case it is needed on some boards. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: add headroom and tailroom to mt76_mcu_ops data structureLorenzo Bianconi
Introduce headroom and tailroom to mt76_mcu_ops data structure in order to unify the routine used for mcu message allocation. This is a preliminary patch to add mt7663u support Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-03-17mt76: always init to 0 mcu messagesLorenzo Bianconi
Always initialize to 0 mcu messages since if they are not propely configured they could hang the firmware. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-03-17mt76: mt7603: make dynamic sensitivity adjustment configurable via debugfsFelix Fietkau

2020-03-17mt76: mt7603: add upper limit for dynamic sensitivity minimum receive powerFelix Fietkau
If the minimum power is raised too much, it can make it impossible for weaker clients to connect, and there are some scenarios where the false detects will not go down no matter how much the sensitivity is adjusted. Fixes connectivity issues in some rare cases 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().

2020-02-14mt76: mt7603: increase dma mcu rx ring sizeFelix Fietkau
The ring is used for looping back tx powersave filtered frames, so it could use some more room, in case more than one aggregate was queued Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: move WIPHY_FLAG_HAS_CHANNEL_SWITCH in mt76_phy_initLorenzo Bianconi

2020-02-14mt76: mt7603: fix input validation issues for powersave-filtered framesFelix Fietkau
Before extracting the tid out of the packet, check if it was qos-data. Only accept tid values 0-7 Also, avoid accepting the hardware queue as skb queue mapping, it could lead to an overrun. Instead, derive the hardware queue from the tid number, in order to avoid issues with packets being filtered multiple times. This also fixes a mismatch between hardware and software queue indexes.

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>
