IPTS on Gen7 needs to be reloaded after suspend

This follows up on the IPTS suspend issues on #74. It seems that a modprobe -r ipts needs to be done before suspend or else Intel ME goes into an inconsistent state.

What doesn't work

Suspend from user interface

pm-suspend
Lid close
Suspend in start menu

However these can be reduced to the other cases.

Platform suspend

# # System wakes up, but touchscreen doesn't work. Notice the lack of "input: Intel Precise Touchscreen"

If system enters this state, shutdown freezes at "reboot" line and requires holding the power button to complete.

Further debugging

To debug the issue further, I ran the following commands after going through "platform suspend."

# rmmod ipts
# rmmod mei_me
# rmmod mei

That worked fine. However, the following causes IPTS to load and causes a kernel oops:

# modprobe mei
# modprobe mei_me

None of {mei, mei_me, ipts} can be unloaded after.

Workaround

I found that if I do rmmod ipts before suspending, then all of the ways of suspending DO work.

Analysis

After a couple more attempts, I found that the problem has a small chance of not occurring. I wonder if this is a race condition between ipts and mei_me, and whether we need to make sure ipts suspends first.

Thought I would leave a quick note to confirm this behaviour, using the same model SP7, but running Manjaro with the packaged surface-linux kernel Linux Maxwell 5.5.7-arch1-2-surface #1 SMP PREEMPT Sun, 01 Mar 2020 13:14:42 +0000 x86_64 GNU/Linux.

I didn't dig as deeply as Daniel, but it after noticing it was confined to waking from sleep I used a wicd suspend/resume service script to automatically unload and reload the ipts module. Seems to be sidestepping the problem quite well for now, so I'll paste in my service file below for any other folks who discover this issue and are looking for a quick fix:

I check the access right of each files and the path to rmmod & modprobe. I can't understand the issue.

Can u help ? Thx a lot

On some systems, bin needs to be replaced with sbin

Thx, it seems to work and start properly.

The oneshot unit only works sometimes for me. most of the time the Touchscreen is still unresponsive on my SP7. Is there any other race condition I am missing ?

my dmesg keeps mentions it not working.

[Surface Laptop 3]

I tried wicd-sleep.service, and the "ExecStop" is working, but "ExecStart" is not working. I have to run rmmod ipts manually before closing the lid.

If you're facing the same problem, I have a workaround: Create the file /usr/lib/systemd/system-sleep/rmmod-ipts.sh with the following content, and make it executable (chmod +x rmmod-ipts.sh).

#!/bin/bash

echo "DEBUG: rmmod ipts at `date`" >> /tmp/a.log
rmmod ipts
exit $?

I have no idea why but changing wicd-sleep.service from sleep.target to suspend.target seems to have fixed the issue so far (Haven't lost touch functionality without turning it off for about a week now). I don't know why because I'm pretty sure that sleep.target is called alongside suspend.target regardless.

Can anyone else confirm whether the script is working in 5.8.5? it no longer seems to be working for me. many thanks

Yeah, the script honestly is just not working anymore so I just turned off the touchscreen entirely at this point.

downgrading back to 5.7.17 seems to solve the problem for me. Manually typing rmmod ipts and modprobe ipts isn't working either with the new drivers @danielzgtg do you know what commands to use for stopping and restarting the drivers on 5.8.5? cheers

I don't have a gen7 device to test, but this should work.

#!/bin/sh

case $1 in
pre)
    systemctl stop iptsd
    modprobe -r ipts
    ;;
post)
    modprobe ipts
    systemctl start iptsd
    ;;

The only difference is that you need to stop the iptsd service before you can unload the kernel module, and start it again after reloading the module.

Put this into an executable (chmod +x <path>) file /lib/systemd/system-sleep/ipts and it should work again.

Confirmed working on SP7. Thank you for the information. Is it possible for you to put this in the SP7 wiki so that new comers don't have to look for this thread? thanks

This seems right for preventing IPTS problems.

However, I forgot to add the two lines about iptsd after iptsd got introduced, and it broke for me today when I suspended. Now, none of the following worked for recovering from the problem:

The original script
The new script
Doing the above after a manual suspend and resume
Doing the above manually
Using "Switch users" to switch to the X server within lightdm

Only a reboot worked, and this problem caused my tablet to freeze during shutdown.

The iptsd error is the same as from #273 :

I'm using this scrip on SP4 and it works. however after sleep, if I rotate the device in GNOME input matrix is not rotated. see this https://github.com/linux-surface/linux-surface/issues/302#issue-718801422

The Surface Go line doesn't use IPTS, so you dont have to enable iptsd. It cannot work.

Thank you, good to know

My workaround stopped working today.

Not even a manual rmmod ipts; modprobe ipts; service iptsd restart worked

Can you please post your dmesg?

This is after the following steps:

Cold start
Login
Suspend
Wait 10 seconds
Press power button to resume
Log back in
Touch screen to see it doesn't work

I also had a boot before that where it suspended and resumed properly with touch, but where a second suspend and resume resulted in broken touch

I am also having the same issue, SL3(I) kernel: 5.10.16-arch1-3-surface

I am suspecting that this might happen due to the revert of the MEI bus patch that I applied, so the driver no longer sends the CLEAR_MEM_WINDOW command on shutdown.

If that command is not sent IPTS keeps around the old buffers, which are freed by the module. The older devices dont have a problem with that, but maybe gen7 requires that you clear out the old buffer addresses before you can start the device again.

We might be able to get it to work by sending CLEAR_MEM_WINDOW on startup. In fact, ipts did that in the past but I removed it because I didnt see the purpose in clearing something that will be overwritten a second later. But eh.

Can you apply that patch to the master branch of intel-precise-touch and try again?

It doesn't compile:

error: ‘rps’ undeclared (first use in this function); did you mean ‘rsp’?
  114 |   error = rps->code != IPTS_RSP_READY_FOR_DATA;
      |           ^~~
      |           rsp

I will try fixing it by changing it to rsp ...

The patched module broke touch even without a suspend.

I will try fixing it by changing it to rsp ...

Whoops, sorry. I fixed the original patch, thanks.

The patched module broke touch even without a suspend.

Thanks for trying. The CLEAR_MEM_WINDOW command now fails with error 14 which means timeout. The old driver from intel ignores that error, so lets try that too. Could you apply this on top of the other patch I posted above?

The double patched module loads fine after unloading the previous one. Without suspending, touch works fine before and after the operation.

However, touch still doesn't work after resume:

Hmm.. an earlier workaround on gen7 was to unload the module before suspending and reloading it when resuming. Are you still doing that? If not, can you try if that fixes the issue?

i.e. https://github.com/linux-surface/linux-surface/issues/89#issuecomment-683780497

I have the following suspend-resume script. It contains my modifications on top of the original script that shipped long ago:

$ cat /lib/systemd/system-sleep/sleep
#!/bin/bash
case $1 in
  pre)    # unload the modules before going to sleep

    # Disable bluetooth if no device is connected
    if ps cax | grep bluetoothd && ! bluetoothctl info; then
      bluetoothctl power off
    fi

    ## Disable bluetooth regardless if devices are connected (see notes below)
    #if ps cax | grep bluetoothd; then
    #  bluetoothctl power off
    #fi

    # handle wifi issues
    modprobe -r mwifiex_pcie;
    modprobe -r mwifiex;
    modprobe -r cfg80211;

    ## IPTS: see notes below
    ## > Remove IPTS from ME side
    systemctl stop iptsd
    modprobe -r ipts
    #modprobe -r ipts_surface
    #modprobe -r intel_ipts

    ## > Remove IPTS from i915 side

    ;;

    modprobe ipts
    systemctl start iptsd

    # Restart bluetooth
    if ps cax | grep bluetoothd; then
      bluetoothctl power on
    fi

    # handle wifi issues: complete cycle
    modprobe cfg80211;

# Notes:
# - For IPTS, see
#   >  https://github.com/jakeday/linux-surface/issues/544#issuecomment-519126757
#   for an explanation/discussion. We do not unload/reload modules for now as
#   the IPTS drivers should be able to resume/suspend without this. If you
#   experience any issues on suspend/resume, please file an appropriate issue or
#   join the discussion linked above so that we can fix it. As a temporary
#   workaround, you may want to uncomment the IPTS-related lines above.
# - For bluetooth: If you have spontaneous wakeups, you may want to disable
#   bluetooth completely, regardless if any devices are connected or not, by
#   removing the `! bluetoothctl info;` part as indicated in the comment (e.g.
#   comment-out the original check and comment-in the one below). Note that you
#   may be required to re-connect your devices after resume if you choose this
#   change

Could you try without the script? For the most part it should be obsolete, the marvell wifi stuff doesnt apply to gen7 devices because Microsoft switched to Intel Wifi chips. The bluetooth stuff was fixed in the kernel iirc.

If that doesnt work try with the minimal script I posted above, so just reload the ipts module and restart iptsd.

I did rm /lib/systemd/system-sleep/sleep; systemctl daemon-reload.

The first suspend-resume worked (though before the patch it also worked sometimes).

Touch stopped working in the next suspend-resume:

I then retried after installing your script (edited to load the right module). I got the same errors

Okay, strange request, but can you downgrade the kernel to 5.10.13 and try with the ipts module from master (without any patches)?

The only difference in that setup would be the MEI bus patch, so if that works I will simply reapply it.

EDIT: Actually, you need a patch, sorry:

I loaded the newer version of the ipts.ko module on Linux daniel-tablet1 5.10.13-surface #1 SMP Thu Feb 4 00:43:10 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux with the new sleep script installed.

On one boot, I was able to suspend and resume 3 times while touch remained functional before I rebooted.

On the next boot, touch stopped working on the first resume. However, it might be related to unloading the old module. Here is the dmesg:

Okay, maybe I need to take a step back on this. Because I feel like I managed to confuse myself, partially by jumping the gun and posting patches right off the bat, instead of asking questions first. Sorry for that.. :(

You said that your workarounds stopped working. Did that correlate to a kernel update? If you downgrade to 5.10.13 with your workarounds, does it work reliably again? (without building the module from master)

Did that correlate to a kernel update?

I don't know if or which yet, but I think it must have. If userspace was allowed to cause these problems then that would be a much bigger problem.

I'll bisect on kernel images from the repo once I have the time

5.10.13 with your workarounds, does it work reliably again? (without building the module from master)

I don't think it would.

The error in dmesg from my second attempt happens before the module from master is loaded. It happens when the old one is unloaded. Both workaround scripts do the unloading, so this is effectively "5.10.13 with your workarounds, [...] (without building the module from master)"

I didn't know how to install the module, so the ipts.ko is still somewhere in my Downloads directory and I'm doing rmmod and insmod with it. Since the problem happens with the old module (second attempt) and not with the new module (first attempt), I wonder whether it'll work reliably once I properly install the module from master

The error in dmesg from my second attempt happens before the module from master is loaded. It happens when the old one is unloaded.

These timeout issues (error 14) can be flaky hardware I think. I had them too when testing one of the patches and they went away after a while (or after a reboot). At the moment I am more interested if the device comes back after suspend, if there arent any errors before suspending.

Actually, I think I found a way to reliably reproduce the timeout issue: When there is unprocessed data waiting, the command will timeout. So you can reproduce the issue on 5.10.13 by stopping iptsd, touching the screen and then unloading the module.

I pushed a branch to the ipts repo: https://github.com/linux-surface/intel-precise-touch/commits/suspend-fun

It should fix the timeout issues, and hopefully also the suspend issues you are having. Could you give that branch a try on kernel 5.10.13 (it needs the MEI bus patch)? To prevent the builtin module from messing things up with timeout errors, you can blacklist it: echo "blacklist ipts" | sudo tee /etc/modprobe.d/ipts.conf

When there is unprocessed data waiting, the command will timeout. So you can reproduce the issue on 5.10.13 by stopping iptsd, touching the screen and then unloading the module.

Are we sure touching the screen is the only way to have unprocessed data waiting? What about the other thing that sends data periodically, which it sounds like would also be "unprocessed data" if iptsd is stopped?

"blacklist ipts"

blacklist barely does anything. We need install ipts /bin/false

Are we sure touching the screen is the only way to have unprocessed data waiting? What about the other thing that sends data periodically, which it sounds like would also be "unprocessed data" if iptsd is stopped?

Yes, thats also unprocessed data.

blacklist barely does anything. We need install ipts /bin/false

Not sure what you mean to be honest. I want to prevent automatic loading of the builtin ipts module, because that can have the timeout issue when you unload it. blacklisting it in modprobe.d works fine for that. If the module is blacklisted it should be easier to properly test if the branch I posted fixes the issue, because you shouldnt get timeout errors.

Touch kept working through 3 boots with 3 suspend-resumes each

Not sure what you mean to be honest

I meant that we need to use echo "install ipts /bin/false" >> /etc/modprobe.d/blacklist.conf.

When debugging a separate GPU problem, someone on Gitter suggested using blacklist i915. It didn't work. You can still modprobe modules even after they are blacklisted. Even if you are not modprobing it yourself, something in the system might be, as demonstrated by that time

prevent automatic loading of the builtin ipts module

install ipts /bin/false is a stronger guarantee for that. By using the /bin/false method, we forcibly break automatic loading of ipts. It's like how systemctl mask is stronger than systemctl disable. By using the stronger method, we don't need to worry about some other script (such as the original suspend-resume script before I edited it to use insmod instead of modprobe) loading the wrong module anymore.

Touch kept working through 3 boots with 3 suspend-resumes each

I totally overread this. That sounds great!

Out of curiosity, was that with the sleep script or without? If it was with the script, could you try without it?

was that with the sleep script or without

With

If it was with the script, could you try without it?

I just performed the same procedure and it still worked without the script

Awesome, thank you for testing!

This should be fixed with the latest kernel updates.

Can confirm. Thanks!
