[PATCH] mt7601u: Fix system freeze after resuming from hibernation

[cantabile]

The firmware running on the device sometimes survives a reboot 
(firmware_running returns 1). When this happens the driver never calls 
request_firmware, which means the kernel's firmware handling code 
doesn't know this firmware should be cached before hibernating. Upon 
resuming from several hours of hibernation, the firmware is no longer 
running on the device, so the driver calls request_firmware. Since the 
firmware was never cached, it needs to be loaded from disk, and this is 
when the system freezes, somewhere in the xfs driver. Fix this by always 
requesting the firmware, whether it's already running on the device or not.

Thanks for tracking this down, but this seems like the wrong
direction.

What's your hard drive?  Is it some complex configuration which
prevents the block device from coming online after resume?  

If it's really because of some peculiarities of XFS the fix should 
go there, no driver will be able to load FW on resume...

My hard drive is a SATA SSD, with a regular MS-DOS partition table, with 
three primary partitions: one ext4 mounted at /boot, one xfs mounted at 
/, one xfs mounted at /home. No encryption, no software RAID, no logical 
volumes, etc.

The kernel has a firmware caching mechanism to make sure that no driver 
needs to load firmware from disk during the resume process. Because 
that's unreliable. See this bit of the documentation: [1]

This is how it works: when the driver's probe callback calls 
request_firmware, that function adds the firmware file's name in a 
devres in your 'struct device'. When you suspend the system, the kernel 
calls fw_pm_notify [2], which goes through all the 'struct device's and 
looks for firmware file names previously added by request_firmware, and 
loads into memory all the firmware files it finds. When you resume the 
system, all calls to request_firmware ought to find the firmware files 
already loaded in memory. After resuming, the kernel calls fw_pm_notify 
again to release the cached firmware files (with some delay).

This caching mechanism currently doesn't always work for your driver 
because your driver doesn't always call request_firmware from the probe 
callback. Because the firmware running on the device sometimes survives 
a reboot.

You can get some very useful messages if you compile firmware_class.c 
with -DDEBUG [3]. This is how I figured out the problem.

Thanks for the info.  Would it be cleaner to EXPORT fw_add_devm_name()
and just call that in case driver sees FW is already loaded?  That
should inform the fw subsystem that we want the image around in case of
hibernation, but there is no need to load it immediately?

No, I don't believe it's cleaner to expose a private function that you 
don't even really need. Remember that calling request_firmware every 
time your driver's probe and resume functions are called is normal. It's 
the expected behaviour.

I'm asking you the extend functionality of a subsystem to be able to
cleanly communicate the intent.  Not export internal functions.

Requesting firmware you don't need and risking failing probe even if FW
is already pre-loaded is not correct.  Reordering you suggest is
brittle and makes little logical sense unless someone guesses your use
case.

Please at least try to do as advised.  Otherwise:

You're right about the reordering not making sense to someone unfamiliar 
with the problem. I can fix that with a comment.

I can change the patch so that request_firmware will only make the probe 
function fail if the firmware is not already running.

If that's not satisfactory, I will try to do what you suggested. (The 
lack of comment from mcgrof@kernel.org doesn't look promising, but maybe 
I'm just impatient.)

Note that using request_firmware() on probe typically is also not an
outstanding idea given it delays boot. Not because looking for the firmware
takes time, but instead because processing firmware typically does on
the device. For instance cxgb4 is an example device where processing
firmware takes a long time.

Delays on probe may mean the "feel good" immediate desktop coming up is delyed.

Specially if its networking... I see no reason why to process firmware on probe.

If one can use a workqueue to process verifying if it needs firmware and loading
later, that's more advisable.

Now, that's all a side topic.

I will for now agree that it seems pointless to request for firmware always
even if you don't need to, and all you want is to just cache the firmware
on suspend. So I welcome a patch but the justification for it really needs to
be documented very well, and the documentation extended as such. In fact
maybe rename the function to something more sensible.

Another use case for the firmware cache (which we need to add the documentation)
is that for hibernation we suspend all devices first, get a snapshot, and then
resume devices so we can then write the snapshot to disk. On that resume step
I don't think devices have access to the hard drive for firmware, so cache is
all we have. This may need some confirmation but I suspect this is the case.
Drivers needing firmware on resume for hibernation may need to cache their
firmware.

I want to understand the case where the firmware is *not* available on resume?
Why did that happen? I seem to have read that on a fresh reboot the firmware
was not needed, and so on probe request_firmware() was not called? Why would
firmware not be required on a reboot?

Quite true, more advanced the FW the longer FW load takes :(  Although
I would be cautious not to cause issues for network/NFS boot...  Perhaps
it can wait for such workqueue to finish?

Yes, that is a good question..  John, do you have a theory?  My initial
thought was that the UEFI/BIOS loads it during pre-boot, but this is a
USB card, so it's a bit unlikely that UEFI will have a driver for it...
Does this happen when rebooting maybe?

Yes, it happens when rebooting:
1) Plug in the dongle. Message about firmware appears in dmesg:

mt7601u 2-3:1.0: ASIC revision: 76010001 MAC revision: 76010500
mt7601u 2-3:1.0: Firmware Version: 0.1.00 Build: 7640 Build time: 
201302052146____
mt7601u 2-3:1.0: Warning: unsupported EEPROM version 0d

2) `systemctl reboot`. Message about firmware does not appear in dmesg:

mt7601u 2-3:1.0: ASIC revision: 76010001 MAC revision: 76010500
mt7601u 2-3:1.0: Warning: unsupported EEPROM version 0d

The dongle is nevertheless perfectly functional after rebooting.

I have no idea why it works like this.

This is an older laptop, no UEFI.

OK, this just confirms that firmware is not needed on reboot sometimes,
but it does not explain *why*. What driver and code lines are involved
so I can go read? Is the vendor involved or not really?

I could imagine a situation where on reboot we just reset a device but
since poweroff is never fully issued the firmware is not lost. So let me
ask, why not do a full reset / shutdown of the device when the interface
goes down?

If there is no gain from the behaviour observed, might as well make
the device work as much others rather than adding an API for a one-off
situation where there is no gain from it behaving in a unique way.

mt7601u_load_firmware() is probably the place to look at.

Not really, we got the vendor to submit the FW to linux-firmware,
that's about it.

IDK what the reset procedure is :S

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:

diff --git a/drivers/net/wireless/mediatek/mt7601u/mcu.c b/drivers/net/wireless/mediatek/mt7601u/mcu.c

+		pr_info("Firmware already loaded but going to reload...");
 
 	ret = request_firmware(&fw, MT7601U_FIRMWARE, dev->dev);
 	if (ret)
 


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?

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

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.

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.)

Oh well, the optimization is not optional then :P

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.

The above log is from "20180227-firmware-cache" kernel plus your 
suggested change that makes it always upload the firmware:

(plus firmware_loader.c compiled with -DDEBUG).

The "MCU response pre-completed!" message also appears pretty often with 
a stock kernel, and the device works anyway.

I recompiled the kernel with CONFIG_DEBUG_INFO=y, but the messages in 
journalctl look pretty much the same as before. There are still question 
marks in the call traces, there are no line numbers, and it still says 
"verbose debug info unavailable". /proc/config.gz contains 
CONFIG_DEBUG_INFO=y. What else do I need to do?

Your patches definitely fix the problem I reported in my initial email.

Huh, if you are using 20180227-firmware-cache, then your diff should instead
be this no?

Hrm, odd.

CONFIG_FRAME_POINTER=y

Maybe.

Right, yes. I just copied the diff from your email instead of git diff.

That doesn't exist in /proc/config.gz, not even commented out. I used 
SymSearch in 'make nconfig', and it finds "FRAME_POINTER":
