Hi all, Dave and me chatted about this last week on irc. Essentially we have:

I only looked at .c sources, since headers are worse wrt having questionable default headers. So about 18 files with clear GPL licenses thus far in drm core/helpers. Looking at where that code came from, it is mostly from GPL-only drivers (we have a lot of those nowadays), so seems legit non-MIT licensed. Question is now what do we do: - Nothing, which means GPL will slowly encroach on drm core/helpers, which is roughly the same as ... - Throw in the towel on MIT drm core officially. Same as above, except lets just make it official. - Try to counter this, which means at least a) relicensing a bunch of stuff b) rewriting a bunch of stuff c) making sure that's ok with everyone, there's a lot of GPL-by-default for the kernel (that's how we got most of the above code through merged drivers I think). I suspect that whomever cares will need to put in the work to make this happen (since it will need a pile of active resistance at least). Cc maintainers/driver teams who might care most about this. Also if people could cc *bsd, they probably care and I don't know best contacts for graphics stuff (or anything else really at all).
