This is a nouveau-specific problem, in fact, Maxwell+ only. LTC = level-two cache. Something specific to NVIDIA hw (other GPUs have it too, but it's always different and controlled by the hw or driver directly - not something that's API-accessible, or even generic across drivers). Also note that the errors only happened when I force-enabled bindless textures in DiRT Rally (via a config option), which is the feature that the patch was implementing. The "missing flush" is in reference to something missing inside of nouveau wrt texture management. There's ample evidence that there's something off somewhere in there. In any case, those ills are in no way related to radeonsi or any other driver.</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>
