2021-10-20mt76: mt7921: fix kernel warning from cfg80211_calculate_bitrateSean Wang
Fix the kernel warning from cfg80211_calculate_bitrate due to the legacy rate is not parsed well in the current driver. Also, zeros struct rate_info before we fill it out to avoid the old value is kept such as rate->legacy.

2021-06-19mt76: mt7921: fix reset under the deep sleep is enabledSean Wang
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: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
