wifi: mt76: mt7915: fix unintended sign extension of mt7915_hw_queue_read()

2023-03-10T08:28:00Z

[ Upstream commit edb0406bda4629ef496f52eb11cbea7e92ed301b ] In the expression "map[i].qid << 24" starts as u8, but is promoted to "signed int", then sign-extended to type "unsigned long", which is not intended. Cast to u32 to avoid the sign extension. Fixes: 776ec4e77aa6 ("mt76: mt7915: rework debugfs queue info") Signed-off-by: Ryder Lee Signed-off-by: Felix Fietkau Signed-off-by: Sasha Levin

wifi: mt76: mt7915: fix mt7915_rate_txpower_get() resource leaks

wifi: mt76: mt7915: rely on band_idx of mt76_phy

2022-12-01T16:29:15Z

The commit dc44c45c8cd0 added band_idx into mt76_phy, so switching to rely on that. Signed-off-by: Ryder Lee Signed-off-by: Felix Fietkau

wifi: mt76: mt7915: enable per bandwidth power limit support

2022-12-01T16:29:15Z

This power should override the per bandwidth max power that the device emits. Signed-off-by: Ryder Lee Signed-off-by: Felix Fietkau

wifi: mt76: mt7915: fix band_idx usage

2022-12-01T16:29:14Z

The commit 006b9d4ad5bf introduced phy->band_idx to accommodate the band definition change for mt7986 so that the band_idx of main_phy can be 0 or 1. Accordingly, the source of band_idx 1 has switched to "phy != &dev->phy" or "dev->phy.band_idx = 1". We still use ext_phy to represent band 1 somewhere in driver, so fix it. Also, band_idx sounds more reasonable than dbdc_idx, so change it. Fixes: 006b9d4ad5bf ("mt76: mt7915: introduce band_idx in mt7915_phy") Signed-off-by: Ryder Lee Signed-off-by: Felix Fietkau

wifi: mt76: mt7915: add basedband Txpower info into debugfs

2022-12-01T16:29:14Z

This helps user to debug Txpower propagation path easily. Signed-off-by: Ryder Lee Signed-off-by: Felix Fietkau

wifi: mt76: mt7915: add full system reset into debugfs

2022-12-01T16:29:13Z

Trigger firmware crash and enable full system recovery through debugfs. This also renames knob "fw_ser" to a clear-cut name "sys_recovery". Signed-off-by: Ryder Lee Signed-off-by: Felix Fietkau

wifi: mt76: move aggr_stats array in mt76_phy

2022-12-01T16:29:13Z

Move aggregation stats array per-phy instead of share it between multiple interfaces. This is a preliminary patch to add mt7996 driver support. Signed-off-by: Lorenzo Bianconi Signed-off-by: Felix Fietkau

wifi: mt76: mt7915: reserve 8 bits for the index of rf registers

2022-12-01T16:29:12Z

The value of regidx of rf registers is combined with WF selection and offset. Extend the WF selection field from 4 to 8 bits since the adie index should also be specified. Signed-off-by: Evelyn Tsai Signed-off-by: Shayne Chen Signed-off-by: Felix Fietkau

wifi: mt76: mt7915: do not check state before configuring implicit beamform

2022-09-15T11:21:39Z

Do not need to check running state before configuring implicit Tx beamform. It is okay to configure implicit Tx beamform in run time. Noted that the existing connected stations will be applied for new configuration only if they reconnected to the interface.
