Thank you for the information. I tried starting up a 13-CURRENT = 20191011-r353427 VM with only one CPU and installed drm-devel-kmod from = ports. The whole VM crashed when I loaded the module! Considering the = 20191018 ISO wouldn=E2=80=99t even load in the VM, and based on what you = said, I=E2=80=99ll just keep an eye on it, and try every now and then = with the devel-kmod to see if anything works. I am not doing anything = with a VM right now that needs the 3d acceleration, but figured if I = could get it to work, that would be a neat thing to play with. = I=E2=80=99d help with the development, but I have never done any serious = programming, so I wouldn=E2=80=99t even know where to start.
