The only thing that will happen is Mac OSX absorbing the code and benefiting. Nothing more.
That's why the makers of these KMS drivers for Linux should make thier code GPL not BSD. Even when BSDed initially, linking to the Linux kernel which is GPL makes the drivers GPL. So those BSD nutcases are violating the GPL as they have always did: http://www.theinquirer.net/inquirer/...en-source-code
I remember when KMS drivers on Linux were at about this point, and people were calling it good enough to start switching. Not all that long ago, either. I'd be surprised if it's stable before Q4, but I'd expect to see it stable before Summer 2014.
Apple already has drivers, though I can't say anything about quality.
This is great news.
With Intel, AMD (ATI) and Nvidia covered, there's only VIA left to support with FreeBSD.
There's still work to be done to make it day-to-day usable, but indeed; this is going to make my life a bit easier. I can't wait for the different KMS projects to all be (good enough to be) enabled by default.
