Oh right. Not sure where I got the idea that we wouldn't use vblank irqs unless fullscreen. After thinking about this for a while I started to question why we're frobbing the AGPBUSY bit all the time. It won't force an exit from C3 unless there's a pending interrupt, so we should just be able to leave it on all the time. I pushed that idea here: git://gitorious.org/vsyrjala/linux.git agpbusy2 I guess the chances of it working are slim, but migth as well try.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
