I don't want to speak for mmacy@ or others, but my understanding was to first implement a linux KPI layer for FreeBSD that is up to date with the current linux kernel code. this should allow for easier integration of the DRM bits from linux onto FreeBSD, and help get other drivers and that are linux specific working. I believe currently work is happening right now to get the lkpi code from drm-next integrated into upstream CURRENT, and some folks are working on creating a drm port/pkg for intel i915 graphics as well as for amd GPU's. This plan should help avoid some of the nastiness you mention, while also keeping GPL'd that is required to get all the bits working correctly out of the base system. at least that is my understanding - i'm sure someone will chime in if i'm off base/confused though :) -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
