Greetings all; I found the u-sd card with a debian-arm buster net-install on it. And I generally like what I see. Then I noticed there was a newer kernel marked preempt-rt. What the hell, give it a shot, and installed it along with the mesa-utils pkgs.
rebooted, runs fine. Ran glxgears full screen, getting about 9 fps. Nowhere near the 27 fps I get out of a raspian buster install, but is still around 7.5 fps faster than jessie or stretch gave me, a quite worthwhile improvement. So, over the next week I'll setup a build environment on a plugged in ssd and see if I can build an arm64, deb format version of linuxcnc. That would be a good sized feather in my hat!
