Only DM thatâ??s open source is amdgpu_dm.the rest will remain closed source.I remember we had discussion around legal issues with our grand plan of unifying everything, and I remember maybe it was John who assured us that it's okay.John can you chime in how it would work with GPLv2 licsense?

I am struggling with that these comminty contributions to DC would be. Us AMD developer has access to HW docs and designer and we are still spending 50% of our time figuring out why our HW doesn't work right. I can't image community doing much of this heavy lifting. > > I don't quite see how that would be legal but maybe I'm missing > something. > > Presumably the situation with the Windows driver is the same. > > I guess you could maintain a separate branch sans community contributions > which would serve as a basis for closed source drivers, but not sure if > that is feasible given your resource constraints. Dave sent us series of patch to show how it would look like if someone were to change DC. These changes are more removing code that DRM already has and deleting/clean up stuff. I guess we can nak all changes and "rewrite" our own version of clean up patch community want to see? > Thanks, > > Lukas -------------- next part -------------- An HTML attachment was scrubbed...
