has anyone had luck with compiling this in manjaro arm rpi4?
A comment in that blog says that they are only working on the 32-bit ones for now:
That comment was from June. It sounds like the guide just have you compile a specific branch of mesa. So this should be doable, if you take the
mesa-git PKGBUILD on our gitlab and change the source to use that repo/branch instead.
I tried it on raspberry OS it is for nothing only for those moving 3D objects what you can download, not acceleration in browser no acceleration in Video players, simply I did not see any difference while using standard programs....
