But as I said I honestly would do the same as user space developer. >From an upstream kernel pov I've never cared about the blobs. I don't upstream should terribly start caring about blobs - if they ship hacks that don't reflect what the open stack does, their problem. Speaking as someone who's pissed off closed source driver teams to no end.

Jokes aside, I think we should look at what's the right thing to do looking at open source only, and if that gets the blobby folks shafted, well so be it. Really not my problem, and I'm pretty sure Dave doesn't care one hair of an inch more. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
