Thus far we've tried to carefully work around the fact that old userspace relied on the AGP-backed legacy buffer mapping ioctls for a bit too long. But it's really horribly, and now some new users for it started to show up again: http://www.mail-archive.com/mesa-dev@xxxxxxxxxxxxxxxxxxxxx/msg45547.html This uses drmAgpSize to figure out the GTT size, which is both the wrong thing to inquire and also might force us to keep this crap around for another few years. So I want to stop this particular zombie from raising ever again. Now it's only been 4 years since XvMC was fixed for gen3, so a bit early by the usual rules. But since Linus explicitly said that an ABI breakage only counts if someone actually observes it I want to tempt fate an accelarate the demise of AGP. We probably need to wait 2-3 kernel releases with this shipping until we go on a killing spree code-wise.
