I would just build from source so I can fine tune for the lowest latency, and have the latest 3D support. Note the following:

It looks super straight-forward, except for the realtime kernel (as usual). I don't see a modern kernel built with Preempt-RT enabled in the raspbian bullseye package archive... Does anyone know if there's a well-liked pre-built official or community-supported Rpi4 realtime kernel somewhere? Or do I have to reconfigure & rebuild the "official" kernel? -- Sebastian Kuzminsky _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
