To fix possibly the race to access register between the WiFi reset and the other context that is caused by explicitly cancelling ps_work and wake_work to break PM_STATE consistency. Deep sleep would cause the hardware into the inactive state, so we forcely put device drv_own state before we start to reset. The patch also ignore the reset request when the procedure is in progress to avoid the consecutive WiFi resets. localhost ~ # [ 2932.073966] SError Interrupt on CPU7, code 0xbe000011 [ 2932.073967] CPU: 7 PID: 8761 Comm: kworker/u16:2 Not tainted 5.4.112 #30 [ 2932.073968] Hardware name: MediaTek Asurada rev1 board (DT) [ 2932.073968] Workqueue: phy0 ieee80211_reconfig_filter [mac80211] [ 2932.073969] pstate: 80400089 (Nzcv daIf +PAN -UAO) [ 2932.073969] pc : el1_irq+0x78/0x180 [ 2932.073970] lr : mt76_mmio_rmw+0x30/0x5c [mt76] [ 2932.073970] sp : ffffffc01142bad0 [ 2932.073970] x29: ffffffc01142bc00 x28: ffffff8f96fb1e00 [ 2932.073971] x27: ffffffd2cdc12138 x26: ffffffd2cdaeb018 [ 2932.073972] x25: 0000000000000000 x24: ffffff8fa8e14c08 [ 2932.073973] x23: 0000000080c00009 x22: ffffffd2a5603918 [ 2932.073974] x21: ffffffc01142bc10 x20: 0000007fffffffff [ 2932.073975] x19: 0000000000000000 x18: 0000000000000400 [ 2932.073975] x17: 0000000000000400 x16: ffffffd2cd2b87dc [ 2932.073976] x15: 0000000000000000 x14: 0000000000000000 [ 2932.073977] x13: 0000000000000001 x12: 0000000000000001 [ 2932.073978] x11: 0000000000000001 x10: 000000000010e000 [ 2932.073978] x9 : 0000000000000000 x8 : ffffffc013921404 [ 2932.073979] x7 : 000000b2b5593519 x6 : 0000000000300000 [ 2932.073980] x5 : 0000000000000000 x4 : ffffffc01142bbc8 [ 2932.073980] x3 : 00000000000001f0 x2 : 0000000000000000 [ 2932.073981] x1 : 0000000000021404 x0 : ffffff8fa8e12300 [ 2932.073982] Kernel panic - not syncing: Asynchronous SError Interrupt [ 2932.073983] CPU: 7 PID: 8761 Comm: kworker/u16:2 Not tainted 5.4.112 #30 [ 2932.073983] Hardware name: MediaTek Asurada rev1 board (DT) [ 2932.073984] Workqueue: phy0 ieee80211_reconfig_filter [mac80211] [ 2932.073984] Call trace: [ 2932.073985] dump_backtrace+0x0/0x14c [ 2932.073985] show_stack+0x20/0x2c [ 2932.073985] dump_stack+0xa0/0xf8 [ 2932.073986] panic+0x154/0x360 [ 2932.073986] test_taint+0x0/0x44 [ 2932.073986] arm64_serror_panic+0x78/0x84 [ 2932.073987] do_serror+0x0/0x118 [ 2932.073987] do_serror+0xa4/0x118 [ 2932.073987] el1_error+0x84/0xf8 [ 2932.073988] el1_irq+0x78/0x180 [ 2932.073988] mt76_mmio_rr+0x30/0xf0 [mt76] [ 2932.073988] mt76_mmio_rmw+0x30/0x5c [mt76] [ 2932.073989] mt7921_rmw+0x4c/0x5c [mt7921e] [ 2932.073989] mt7921_configure_filter+0x138/0x160 [mt7921e] [ 2932.073990] ieee80211_configure_filter+0x2f0/0x3e0 [mac80211] [ 2932.073990] ieee80211_reconfig_filter+0x1c/0x28 [mac80211] [ 2932.073990] process_one_work+0x208/0x3c8 [ 2932.073991] worker_thread+0x23c/0x3e8 [ 2932.073991] kthread+0x140/0x17c [ 2932.073992] ret_from_fork+0x10/0x18 [ 2932.074071] SMP: stopping secondary CPUs [ 2932.074071] Kernel Offset: 0x12bc800000 from 0xffffffc010000000 [ 2932.074072] PHYS_OFFSET: 0xfffffff180000000 [ 2932.074072] CPU features: 0x080026,2a80aa18 [ 2932.074072] Memory Limit: none Co-developed-by:

BIT(0) in MT_EE_NIC_CONF_1 is use to notify the driver if the radio RF switch is controlled through a gpio. Use dev_debug instead of dev_err to log this info. Signed-off-by:

Even if this is not a real issue since mt76_tx is never run with wcid set to NULL, fix a theoretical NULL pointer dereference in mt76_tx routine Fixes: db9f11d3 ("mt76: store wcid tx rate info in one u32 reduce locking") Signed-off-by:

Add runtime configuration for bitrate mask. This update firmware rate control to add a boundary on top of table to limit the rate selection for each peer, so when user set bitrates vht-mcs-5 1:9, which actually means nss = 1 mcs = 0~9. This only applies to data frames as for other mgmt, mcast, bcast still use legacy rates as it is. Note that driver does not support GI configuration. Example: iw dev wlan0 set bitrates vht-mcs-5 1:9 he-mcs-5 2:7 iw dev wlan0 set bitrates legacy-5 6 he-mcs-5 2:0-11 Signed-off-by:
