4 years ago Was this dmesg log taken when resuming from hibernation? If not, can you get one that was? Also can you clone https://github.com/linux-surface/surface-aggregator-module and run sudo modprobe surface_sam_debugfs and
./scripts/ssam/evreg.py sam-enable 0x08 0x00 0x00and check if that gets the keyboard working again?

4 years ago Okay, I've set up hibernation for my SB2 and I've been able to reproduce this (with battery events though). Looks like the SAM events get disabled during hibernation entry but not enabled during resume. I'll try to figure out a bit more about this.

commented
4 years ago As far as I can tell, the controller (hardware) disables the events. Should be fairly straightforward to enable them again on resume, but I'll have to make a couple of changes for that.

4 years ago Hmm I use hibernation but things seem to function fine on SL3. I'll double check later

4 years ago I feel like the whole event stuff is sometimes a bit random. To me it kind of seems like some events (keyboard on SL3) might be default-enabled. We've had the wrong enable call for that for quite a long time (until I worked on the SB3 keyboard support), and I have never heard any of issues that the keyboard doesn't work due to the events being disabled. On the other hand, it could also be that the controller on the SL3 doesn't reset the event state after reboots (so if Windows enables the events once, they'll be enabled forever if we don't disable them, which could also explain this behavior).
Although this could also be a setup difference: AFAIK there's a loader kernel that loads the hibernated kernel state from disk. If the loader loads the SAM drivers, it's going to enable the events again before giving control over to the hibernated one. I'm not that familiar with how and what exactly the initial kernel loads, but I think it might be possible that if it loads stuff from initram and you have the SAM drivers in initram, that could also be what's happening.
My plan is to re-enable all events on hibernation exit, which should work regardless if events have already been enabled or not (if a specific event has already been enabled, the call to enable it again is just going to be ignored by the controller). Maybe also disable all events on hibernation entry for consistency.

4 years ago Oh yeah I think initramfs explains it -- it initializes the driver at boot so I can enter the LUKS password before resume from hibernation kicks in

4 years ago I think disabling all events before hibernation might also improve power consumption?

4 years ago I think disabling all events before hibernation might also improve power consumption?
I doubt that. At least on my SB2, I can't really see a difference between S4 and S5. Not sure if S4 even works properly and it doesn't fall back to S5 automatically. And events should only be disabled in those states. S2idle kind of relies on the events being there for the wake-up stuff (if that were implemented).
Apart from that, I don't think the events have much influence on power consumption. I think putting the device in a lower-power mode is probably handled via the D0-exit notifications on the newer devices and the display-off notifications on the older ones.
I'm wondering right now how we have to deal with the HID devices, especially the touchpad on SB3/SL3. There seems to be a reset_resume function for HID drivers, which on the hid-multitouch driver calls mt_set_modes (AFAIK that should be the function sending the multitouch feature reports). Looking at the i2c-hid driver, we'll have to call that function (and the suspend function) ourselves.
An alternative to this would be to just remove the HID devices before hibernation and add them back after. But that would be a bit annoying because we'd have to remove them in the freeze phase before the PM image is generated, then add them back in the thaw phase for consistency and error handling, then remove them again when we actually enter hibernation, and, finally, add them again in restore/resume from hibernation.

4 years ago @raphtlw Okay, events should now get re-enabled when resuming from hibernation. Can you test the module in the master branch? To do that, clone the repo, cd into the module/ directory, then run sudo make dkms-install, reboot and start testing. After you've done, you can uninstall the module again via sudo make dkms-uninstall (again running that from the module/ directory).
qzed
commented
4 years ago HID devices should now also be properly suspended and resumed via the appropriate callbacks.

4 years ago @qzed unfortunately running sudo make dkms-install gives me an error.
Error! Bad return status for module build on kernel: 5.8.3-arch1-1-surface (x86_64)
qzed
commented
4 years ago Ah, looks like you're using a different GCC version than the one with which the kernel has been compiled (10.2.0). I believe you'll need to install that from the testing repositories on Manjaro.
qzed
commented
4 years ago A new kernel release containing the changes is currently building. Should be live later, I'll ping this issue once it is.
qzed
commented
4 years ago New releases will be live in a couple of minutes. Can you confirm that the issue has been fixed?
qzed
commented
4 years ago Seems to be working according to https://github.com/linux-surface/linux-surface/issues/268.
After waking up from hibernate mode, the keyboard does not work and I cannot log back into the system.
