DRAFT: OpenXR Playspace Mover

[RinLovesYou]

Marked as draft because the monado side has to be cleaned up and expanded before a merge request can be made. I'm putting this here so it's visible to people and we no longer need to pass patches around by hand.

This code interfaces with a custom libmonado function I wrote. The monado changes can be found here

Tries to find libmonado by getting monado-service's location. If this fails, you can run it with LIBMONADO_PATH="path/to/libmonado.so". As the monado side gets cleared up this MR will add integration with libmonado-rs, etc.

I should also mention that inputs have only been mapped for Index controllers, as that's all i have. Take a look at input/openxr changes and let me know where things should be mapped please.

Nevermind, the find libmonado automatically commit breaks this for WiVRn. can we still have LIBMONADO_PATH to be able to override the behavior specific to monado-service?

For everyone who wants Vive Tracker FBT and Space drag at the same time: https://gitlab.freedesktop.org/ToasterUwU/monado/-/tree/vive_tracker3

Its just a combination of the vive_tracker3 branch of Babbles Bones Monado Fork and the Monado Fork with Space Drag patch made by @RinLovesYou as mentioned above.

I tested this just now with envision, and both things work perfectly in combination. Im SOOO happy rn!!!

So if you wanna use this combination and use Envision, enter https://gitlab.freedesktop.org/ToasterUwU/monado#vive_tracker3 as your Monado repo and https://gitlab.com/BabbleBones/OpenOVR#htcx-fbt as your OpenComposite repo.

cleaned this up here #44 and i will be merging if it works on:

• vanilla Monado (non-functional, no crash)
• playspace patched Monado (functional)
• playspace+fbt patched Monado (functional)
• unpatched WiVRn (non-functional, no crash)

[galister]

Monado playspace mover is included in WlxOverlay-S v0.4.0, the patch on the Monado side is still required for it to work.

Closing this as now there's a standard implementation that's been merged into upstream Monado.
