We have seen some though asking if we couldn't combine llvmpipe with less capable gpus to make a driver offering more features, that is executing the stuff the gpu can't do with llvmpipe (but no, we really can't in any meaningful way). This proposal sounds even more ambitious in some ways, I certainly agree we can't make it happen. With Vulkan, it may be the developers choice if multiple gpus are available which one to use for what, so theoretically there might be some way there to make something like that happen, but I've no idea there really (plus, unless you're looking at something like at least 5 year old low-end gpu vs. 8-core current high-end cpu, there'd still be no benefits even if that could be made to work). There is one thing llvmpipe is "reasonably good" at compared to gpus, which is shader arithmetic (at least for pixel shaders, not running in parallel for vertex ones, with tons of gotchas as we don't currently even optimize empty branches away), but there's just no way to separate that.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
