2022-12-01wifi: mt76: add info parameter to rx_skb signatureSujuan Chen1-1/+1
This is a preliminary patch to introduce WED RX support for mt7915.

2022-12-01wifi: mt76: mt76x02: simplify struct mt76x02_rate_powerFelix Fietkau1-3/+2
- remove stbc, because mt76x0 doesn't support it and mt76x2 uses the same values as HT/VHT - reduce vht array to 2 elements, because VHT MCS0-7 are the same as HT Signed-off-by: Felix Fietkau <nbd@nbd.name>
2022-12-01wifi: mt76: move mt76_rate_power from core to mt76x02 driver codeFelix Fietkau1-0/+15

Take the link into account in the QoS settings (EDCA parameters) APIs. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-06-20wifi: mac80211: split bss_info_changed methodJohannes Berg1-1/+1
Split the bss_info_changed method to vif_cfg_changed and link_info_changed, with the latter getting a link ID. Also change the 'changed' parameter to u64 already, we know we need that. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-02-03mt76: mt76x02: improve tx hang detectionFelix Fietkau1-1/+1
Instead of checking if any queue has not made progress since the last run, only trigger hang detection if one of the queues has not made any progress in 10 subsequent runs. This should reduce false positive firmware restarts Signed-off-by: Felix Fietkau <nbd@nbd.name>
2022-02-03mt76x02: improve mac error check/reset reliabilityFelix Fietkau1-0/+1
On AP mode devices, check beacon tx counters to detect MAC errors. When an error is detected, stop the MAC before resetting it Signed-off-by: Felix Fietkau <nbd@nbd.name>

2021-01-26mt76: move chainmask in mt76_phyLorenzo Bianconi1-2/+0
Move chainmask from driver phy to mt76_phy since it is used by all drivers. This is a preliminary patch to create a common mcu library used by mt7615 and mt7921 drivers Co-developed-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-07-21mt76: vif_mask to struct mt76_phyFelix Fietkau1-1/+0
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>
2020-05-28mt76: fix per-driver wcid range checks after wcid array size bumpFelix Fietkau1-1/+2
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: mt76x02u: Add support for newer versions of the XBox One wifi adapterMatthew Garrett1-0/+1
The current version has a new USB ID and reports as an 0x7632 device. Adding the IDs results in it working out of the box. Signed-off-by: Matthew Garrett <mjg59@google.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: mt76x02: fix handling MCU timeouts during hw restartFelix Fietkau1-0/+2
If a MCU timeout occurs before a hw restart completes, another hw restart is scheduled, and the station state gets corrupted. To speed up dealing with that, do not issue any MCU commands after the first timeout, and defer handling timeouts until the reset has completed. Also ignore errors in MCU commands during start/config to avoid making user space fail on this condition. If it happens, another restart is scheduled quickly, and that usually recovers the hardware properly. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt76x02: split beaconingMarkus Theil1-2/+1
Sending beacons to the hardware always happens in batches. In order to speed up beacon processing on usb devices, this patch splits out common code an calls it only once. Beacons are sequentially written into the beacon memory area, by tracking its usage with the dev->beacon_data_count. For MBSS support and buffered traffic dev->beacon_data_count is used to create the bypass mask. The code is also adapted for the mmio part of the driver, but should not have any performance implication there. MBSS tests were performed with AVM AC860 USB NIC with temporary support for 5 BSS'. Different combinations of active vifs were created and brought up. Afterwards connection and data transfer was tested for the announced BSS'.

2020-02-14mt76: mt76x02: fix coverage_class typeLorenzo Bianconi1-1/+1

2020-02-14mt76: introduce struct mt76_phyFelix Fietkau1-1/+4
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>

2019-05-01mt76x02: make beacon slots bigger for USBStanislaw Gruszka1-1/+2

Since some USB device IDs are duplicated between mt76x0u, mt7601u and mt76x2u device, check chip version on probe and return error if not match the driver. Don't think this is serious issue, probe most likely will fail at some other point for wrong device, but we do not have to configure it if we know is not our device.

2019-03-07mt76: mt76x02: disable ED/CCA by defaultFelix Fietkau1-0/+1
This feature has been reported to cause stability issues on several systems. Disable it until it has been fixed and verified. It can still be enabled through debugfs Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-03-07mt76: mt76x02: reduce false positives in ED/CCA tx blockingFelix Fietkau1-0/+3
Full tx blocking (as opposed to CCA blocking) should only happen if there is a continuous non-802.11 signal above the energy detect threshold. Unfortunately the ED/CCA counter can't detect that, as it also counts 802.11 signals as busy. Similar to the vendor code, implement a learning mode that waits until the AGC gain has already been adjusted to the lowest value (due to false CCA events), and the number of false CCA events still remains high, and the blocking threshold is exceeded for more than 5 seconds.

2019-02-26mt76: mt76x02: issue watchdog reset on MCU request timeoutFelix Fietkau1-0/+1
MCU request timeout usually indicates that the device is no longer responsive, and it usually does not recover without a reset Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76: measure the time between mt76x02_edcca_check runsFelix Fietkau1-0/+1
Based on system load and time needed by other calibration runs, the time between dev->mac_work runs can vary quite a bit. Calculate busy time based on the actual time difference in order to avoid potentially over-estimating busy time, which could lead to unnecessary tx blocking. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76: run MAC work every 100msFelix Fietkau1-0/+1
ED/CCA Tx blocking checks need to be run every 100 ms in order to avoid triggering too late and keeping tx blocking on for too long Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76x02: use commmon add interface for mt76x2uStanislaw Gruszka1-2/+1
