HiRes scrolling?

[kebien6020]

Both the linux kernel and libinput support high resolution mouse scrolling. Given that you can set an analog axis to scroll and the analog part is already transferred to the scrolling speed I think it would work even smoother if you emitted scrolling events other than full notches of scrolling.

To clarify, when I scroll with my mouse I get these kind of uinput events (from evtest):

Event: time 1699326367.318471, type 2 (EV_REL), code 11 (REL_WHEEL_HI_RES), value -24

When scrolling faster I get higher values on the REL_WHEEL_HI_RES events.

With antimicrox, this is what I get:

With the analog amount of the button press (I'm using my trigger buttons) only correlating with the frequency of events, but not with the value.

Have you considered supporting hires scrolling? Maybe there's already support but my current configuration does not produce these events?
