I would like to check if that does not break the PS2 active multiplexing support. In particular, this can be checked with Thinkpads which have both a trackpoint and a touchpad. But possibly other laptops will be interesting as well.
To test:
Install the image from this change
Verify that trackpoint and/or touchpad work as wanted
Verify that both input devices (touchpad and trackpoint) are visible in Input preferences if they already were without this change
grep ps2 /var/log/syslog to see if there is anything strange there
If some people can confirm that this works as intended on thinkpads, I can merge this change. I don’t want to break your pointing devices and I’m not sure what I did will work correctly.
I’ve built the ps2 busmanager with your linked patch and put it into /system/non-packaged/add-ons/kernel/bus_managers. Rebooted and everything seemed fine. Until I touched my touchpad. The PS2 mouse in the Input preferences disappeared with this entry in the syslog:

This is the complete output of cat /var/log/syslog | grep ps2:

On another try, my keyboard went as well…
EDITED to add: This is not on a ThinkPad, but a Schenker notebook.
Hello,
Thanks for the feedback. I have now updated the change with a different approach, which should cause less problems. It would be great if some more people could test this one before I break everyones keyboard or touchpad
Thanks!
I have a Toshiba Portege Z30, which has both a trackpoint and a touchpad (and a touchscreen, which surprinsingly works!). None of them works, and they’re not recognized by listdev or Devices.
Syslog endlessly repeats the following lines:
KERN: ps2: hot plugin of input/mouse/ps2/0 KERN: ps2: device input/mouse/ps2/0 still active, republishing... KERN: ps2: devfs_unpublish_device input/mouse/ps2/0, status = 0x80006003 KERN: ps2_dev: reset failed: I/O error KERN: ps2: devfs_publish_device input/mouse/ps2/0, status = 0xffffffff
My mind plays tricks on me, as my relationship with Haiku is on and off, but I’m pretty sure both the touchpad and the trackpoint were working sometime around 2022. I guess I could download an old image and try…
I didn’t notice this thread because I had not got a Thinkpad T480s, yet.
I wonder if the issue here may have to do with this very thread.
The symptom looks similar: the Elantech driver is republished repeatedly and both the trackpad and the trackpoint do not work.
The keyboard does, however.
