qmk_kernel_module VS evsieve

With QMK Kernel Module one could skip MCU altogether and just use one Linux SBC. But sadly that module is not maintained.

Currently I'm trying to get the qmk linux kernal module up and working properly. Is there any recent projects or documentation on using a rpi0 for keyboards? I could write out a device tree program, but that would be a pretty big headache.

My ideal scenario here would be to just use a pi 0 as the controller fully, but from what I can tell, the only real options for that are attempt to extend/iterate the kernel module that u/jackhumbert wrote for fun as it isn't feature complete qmk or write something in circuitpython or similar. Given the choice I'd rather not reinvent the wheel and just have full fat qmk on tap.

Same with evsieve: I can see the keys I press, like in wev, but the remap doesn't work for the keyboard or the mouse:

My best suggestion for you is to leverage evsieve: https://github.com/KarsMulder/evsieve

There are many other software tools such as https://github.com/jtroo/kanata and https://github.com/KarsMulder/evsieve. The main difference with 𝑥MK is that you can use native QMK and ZMK.

Ironically I know you can do this in i3 and xorg/gnome using xmodmap or editing the xkb file. I'm pretty sure wayland compositors should be able to read xkb-compliant files but the recommended way of loading that in is probabaly different between various compositors? You could also use a "second generation" interception tool that works at the event device level.

You might want to try evsieve, it even has an example about toggling devices and it concludes with a hint on how to get this to work for 2 VMs.

Evsieve is amazing in general you sould check it out 🙂

evsieve has solved that for me, as the virtual device created is always available; it starts when I log on my computer and stay open forever.

evsieve can remap. I haven't used it yet but you can find it here: https://github.com/KarsMulder/evsieve

If this feels a bit limited (you have a few predefined options), there's also evsieve. Which allows you to do a lot more (like selective key pass-through, shortcuts, etc.).
