[7613] mt7613 wlan scan cause mcu timeout #511

Open ptpt52 opened 3 years ago

ptpt52 commented 3 years ago

chip is mt7613

I try to ubus call iwinfo scan {"device": "wlan1"} after Multiple scans this issue happens

ptpt52 commented 3 years ago

here is how to reproduce it

while :; do iwinfo wlan1 scan; echo; uptime; sleep 1; done

any help? @nbd168

ptpt52 commented 3 years ago

it is likely that no issue on mt7615 chip I do the same test one mt7615, no issue

Borromini commented 3 years ago

@ptpt52 I am seeing this message as well, maybe it's unrelated, but I have two MT7613BE radios here (EAP235-Wall) and it eventually happens on both at some point. It's not a question if, it's a question when. Those timeout messages will fill the log for a while and eventually the radio just dies. I've only seen this when the radios idle - I have pushed hundreds of gigabytes over the radio and that works just fine it seems, it's just when it's idling that at some point it seems to go wrong. I had no way to trigger it but just wait (sometimes it's within a few hours, sometimes it's multiple days though).

I ran your iwinfo command, and this is what logread shows (OpenWrt 21.02 with latest mt76 driver from OpenWrt master):

I have pinged nbd about this on IRC a while ago and was asked earlier on to switch on firmware debugging, like this:

echo 1 > /sys/kernel/debug/ieee80211/phy1/mt76/fw_debug

I can't say it's the same issue, but at least it's the same error message... I was asked to bisect also, and it looked like with the 2021-01-14 version, it worked fine, but with the 2021-01-27 one it broke. I have attempted multiple bisects but eventually I'd end up with a commit that git marked as bad, only to find out that reverting it didn't help either. So I'm at a loss, but hopefully the above can help.

I have two MT7615 devices here as well, those get multiple days of uptime and no issues like this. They actually run a WDS and form part of the backbone in the home network here.

ptpt52 commented 3 years ago

@Borromini thanks for you reply it is likely that it trigger the issue after you run the iwinfo scan command?

ryderlee1110 commented 3 years ago

can you try this patch https://patchwork.kernel.org/project/linux-wireless/patch/8157df1026bb9ea20fd39ce58b8abef9a1cedd37.1616657048.git.ryder.lee@mediatek.com/ to see if system can be recovered back?

Borromini commented 3 years ago

it is likely that it trigger the issue after you run the iwinfo scan command?

Running your command definitely triggered the timeout message, and the radio died. I ran your command at 23:18, more or less right after I SSH'ed into the device (start of the log excerpt). Log wasn't filtered, so everything you see here is the firmware debugging stuff + the kern.err messages. It looks like it only needed a single 'iwinfo scan' to break.

@ryderlee1110 Thanks I will give that a shot.

ryderlee1110 commented 3 years ago

@Borromini which firmware you're using? please apply https://patchwork.kernel.org/project/linux-wireless/patch/02d52818307a85b66e59ca11e36a9da47e2fe4df.1616657048.git.ryder.lee@mediatek.com/ as well? I fixed a mt7615 scan issue. but maybe it's a different one.

Firmware looks right. Anyway, we were not deeply involved in mt7613 on mt76. it should work but maybe not 100% perfect.

@ryderlee1110 test all your patch still issue and reset recovery not ok

ptpt52 commented 3 years ago

with @ryderlee1110 's patches @Borromini and I am trying to slow down the iwinfo scan frequency say, scan it in 60s interval

while :; do iwinfo wlan1 scan >/dev/null; echo $((i++)); uptime; sleep 60; done

and the mcu timeout issue not happens

I did scan in 1 second interval on chip mt7615, no issue happens

while :; do iwinfo wlan1 scan >/dev/null; echo $((i++)); uptime; sleep 1; done
ryderlee1110 commented 3 years ago

OK. Looks like a different issue on mt7613.

ptpt52 commented 3 years ago

@ryderlee1110 one thing your patch solve is that the iwinfo scan never kick sta client, and client could keep stream while no scan doing

ryderlee1110 commented 3 years ago

yes, that's one of issues I fixed for mt7615.

ptpt52 commented 3 years ago

@ryderlee1110 hello, may I ask you something? I can get chip temperature via

cat /sys/kernel/debug/ieee80211/phy1/mt76/temperature 
Temperature: 45

on chip mt7615

but cannot get it on chip mt7613, it always return 0:

cat /sys/kernel/debug/ieee80211/phy1/mt76/temperature 
Temperature: 0

what is the difference between them?

ryderlee1110 commented 3 years ago

@ptpt52 I don't know, it could be command id change etc. Although 7613 reuses 7615 code, I still think there might be some flow changes needs to be modified.

nbd168 commented 3 years ago

Today I fixed reset recovery on MT7622 in a way that might also help MT7613. Please test the latest version

ptpt52 commented 3 years ago

@nbd168 thanks, I would test it next Monday

ptpt52 commented 3 years ago

@nbd168 @ryderlee1110 very strange, with the latest code (https://github.com/openwrt/mt76/commit/465dda65ee8415169cc39596f913a50b5ba4f5a9), the mcu timeout never happens I am not sure which commit fix it.

ptpt52 commented 3 years ago

maybe the 0-terminating code ... commits fix it? or the reset recovery changes?

ptpt52 commented 3 years ago

@nbd168 @ryderlee1110 here to report back the mcu timeout issue still exists an cannot recovery

ptpt52 commented 3 years ago

it just become not esay to triger

ptpt52 commented 3 years ago

the mcu timeout issue happened accidentally, but it is hard for me to reproduce it, maybe it is some sort of hardware issue?

Borromini commented 3 years ago

Here it ranges from under an hour to multiple days for it to pop up. Happens on both MT7613 devices. I just got a third back (was on loan for porting OpenWrt) and I'll be testing that one as well.

ptpt52 commented 3 years ago

@Borromini should it be related to chip temperature?

porentak commented 3 years ago

If it helps, ext_eid=26 is EXT_EVENT_BEACON_LOSS.

ptpt52 commented 3 years ago

what is I disable beacon_offload on driver? @nbd168 @porentak

ptpt52 commented 3 years ago

I am going to call mt7615_mcu_beacon_loss_event() in ext_eid reach EXT_EVENT_BEACON_LOSS

Borromini commented 3 years ago

@Borromini should it be related to chip temperature?

That's one of the things I found when looking for possible mitigations, but at least for me lowering the transmit power didn't seem to make much of a difference. No idea how big a factor TX power is in the overall power consumption

ptpt52 commented 3 years ago

also I notice that MCU_EXT_EVENT_PS_SYNC ext_event comes up if iwinfo scan and it is correct to just ignore it?

@Borromini use my changes in https://github.com/ptpt52/mt76/commit/36ed7ea7962ca2ed7cfa77de62fb123658bdae6d Test to see if the mcu timeout issue is fixed

ryderlee1110 commented 3 years ago

Just note that the mcu_beacon_loss_event format of mt7615 is different compares to connac one. struct mt7615_beacon_loss_event { u8 bssid[8]; u8 reason; u8 rsv; } __packed;

Also, I think we should check reason to update new beacon to firmware (if error happens ...). As for PS_SYN is useless in mt76 you can ignore it.

ptpt52 commented 3 years ago

@ryderlee1110 thanks for the note and I notice there may be some more difference something like get_temperature from mcu...

ryderlee1110 commented 3 years ago

that's why i don't want to drag every chip into mt7615 :) firmware stuff is always messy.

ptpt52 commented 3 years ago

@ryderlee1110 should I use the firmware file in bin/mt7663/rebb/mt7663_patch_e2_hdr.bin in property driver?

ryderlee1110 commented 3 years ago

I don't know actually ... if it's from property driver and works for you then I think it's fine. But you might need to handle few format changes. I think it's ok to add bcn_loss_event since mt7613 looks the same as mt7615 here.

ptpt52 commented 3 years ago

what is /lib/firmware/mediatek/mt7663_n9_rebb.bin and where to get it? @nbd168 @ryderlee1110

ext_eid=35 that means EXT_EVENT_ID_ASSERT_DUMP = 0x23 something bad happens in the chip?

hello, @LorenzoBianconi what do you think of this issue? the mcu timeout happens after random hours of time. the code is the latest. kernel 5.4 in openwrt master

ptpt52 commented 3 years ago

@ryderlee1110 so I know something about the mcu timeout if mt7615_mcu_set_fw_ctrl call, the muc timeout issue happens?

ptpt52 commented 3 years ago

I just hack disable any pm ctrl for mcu, and hope this would help with the mcu timeout issue
