What I'd like to be able to do is setup is a 64bit system including the libraries from the userland repo: https://github.com/raspberrypi/userland. I suspect vc4graphic is something different, isn't it? But maybe you're right and those libs will never be built, as I see that according to https://github.com/raspberrypi/userland/pull/347 not everything builds in userland. In the recipe I however see that the ARM64 macro is defined and so I'm asking myself which libraries are currently supported and which are not. Anyone who knows? Thank you! As far as I know, machine configuration for raspberrypi3-64, at least in master branch of meta-raspberry does set vc4graphic in MACHINE_FEATURES, which in turn selects mesa instead of userland exclusively. This is what the metadata say, and what I recently experimented myself while switching to 64bit builds. I'm not using graphics, but found convenient to monitor RPi temperature via vcgencmd tool that comes with userland. Had a recipe of mine RDEPENDing on userland and found out that this was breaking the 64bit build. For me it was just a matter of using a different source for temperature monitoring. In the end, Herve's explanation gives the more technical background.
