I checked.

static inline int firmware_running(struct mt7601u_dev *dev)                     
{                                                                               
        return mt7601u_rr(dev, MT_MCU_COM_REG0) == 1;                           
}

static int mt7601u_load_firmware(struct mt7601u_dev *dev)                       
{  
	...
        if (firmware_running(dev))                                              
                return 0;    

There you go. That's why. Now one would have to check the spec or
ask a person at the company what it means when:

	MT_MCU_COM_REG0 (0x0730) == 1.

Note that when we load the firmware we use the same check on intervals until
this is true to confirm or deny if the firmware got loaded.  I can only infer
this just means that the firmware is loaded and the device is ready. So this
just seems like an optimization given mt7601u_upload_firmware() seems to hint 
that this this device can take up to 100 * 10ms = 1s to load. Ie, we check
every 10ms to see if the firmware loaded, and we do so 100 times, so minimum
time expected for firmware load can take may be 10ms, and max 1s.

I'd be curious if someone who can trigger the situation can test what
happens if you use:

If it does, one option is mt7601u_cleanup() can use some love to really shut down
the device more... But its not clear to me what else could be done and I'm very
inclined to believe its not sensible.

The idea of an optimization of *not* having to load firmware one more time if
it already has it since power hasn't been shut off on the device seems sensible
to me.

Give the few deltas above a quick test just to fill in curiosity if you like
and to be complete -- I'll post RFCs shortly for you Cantabile to test, is
that your name?

This change brings no new messages from mt7601u in dmesg (other than 
this pr_info), and the device works fine, as far as I can tell.

"Calling mt7601u_disconnect" does not appear in journalctl after a reboot.

OK so we know that the optimization is optional, not a requirement.
That may be worth extending in documentation on the driver.

Oh, I didn't expect it to come up during startup, I was wondering if it did
trigger while going down on reboot.

Hi Luis,
This driver does not implement a .shutdown() callback so that might be 
one reason and the usb subsystem does not call the disconnect for 
whatever reason.

Ah, that's one missing callback then. Hrm, well I suppose its optional and
without it, its just an optimization given there is no issue in keeping the
power on on the device and it retaining the firmware upon boot.

Note that the on interface stop all the DMA and MAC is stopped so I suppose
that is sufficient from an 802.11 perspective.

Thanks for chiming in!

I may have spoken too soon. mt7601u kind of exploded after resuming from 
suspend to RAM. Maybe it has nothing to do with this change, but well. 
The system froze after the KDE lock screen appeared, and a few minutes 
later the Caps Lock LED turned on. I attached journalctl output in case 
it's interesting.

I meant that it doesn't appear among the messages from the shutdown part 
of rebooting. (I can only check after rebooting.)

I take it that was a debug print from you?

This is interesting. Batched requests are requests we get when we detect there
are multiple request for the same firmware. But come to think of it, that
should also pop up whenever we use firmware caching, given firmware caching
does a fake request, so we cache the firmware locally for a while. So that's
probably why we see that message. In other words I can probably remove the
print for batched requests if the firmware was cached, I believe.

An issue immediately. So it should mean the firmware load didn't likely work
correctly.

It may be good to figure out where that happened on the driver, likely
after calling mt7601u_mcu_wait_resp() :)  and the return value of -110
should help more.

Hrm. Its not clear to me if this was from resume or an action
brought on by a new suspend.

Either way the 802.11 device is barfing.

And if its a race between suspend/resume it may be a driver issue.
Try to reproduce without the changes which disable the optimization.

If you can reproduce that's an upstream issue.

If not, it can be a race with opting out of the optimiziation, but still, to
create a crash seems bad and I would expect this crash to be a driver issue.
If the device misbehaves for whatever reason it should not crash the system.

And since no debug info is available we ca't do much more to look at this
issue. You can recompile with debugging symbols enabled (look online), and
it may help further.

OK.

So you mean to say this happens with the stock kernel (except the debug prints
you added)?

That is, you didn't force to upload the firmware on the above log.

Also, the above log is not from a kernel with the patches I posted to fix the
issue and issue a cache request when the device already has a firmware already
loaded?

Correct?

Ah, so you really are kicking into high gear suspend/resume or hibernation/resume.
Note that there may be some fun races there with the driver perhaps. Who knows.

To get clear logs you must.

But if the patches I posted help, I guess we already have a solution, The rest of
these email exchanges are all just hypothetical exercises.

Curious, will it really fail?

Note that I see mt7601u_stop() just calls mt7601u_mac_stop(). The big cleanup
happens via mt7601u_cleanup(), but I see mt7601u_disconnect() calls it.

Just curious, does that not get called on shutdown?
