Rather than relying on a linear framebuffer, maybe we could invent some new interfaces between our driver and the AMD driver that might allow for higher performance. I still think we need to fix the LinearFramebuffer option, but we should explore something better as well. Does your driver blit directly into the framebuffer we use for scanout? Or do you blit from it to get current screen contents? Either way, we may be able to be more efficient if we can leave the scanout buffer in tiled format and use the Intel BLT engine to do tile conversion for us.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
