From the other hand with the i915 KMD level programming we can reprogram the state we lost. Thus, we probably will follow with the KMD level slice programming. Here are the related patches: * <a href="https://patchwork.freedesktop.org/series/29715/">https://patchwork.freedesktop.org/series/29715/</a> - patch series to enable slice programming for Gen8+ (most recent respin) * <a href="https://patchwork.freedesktop.org/series/29564/">https://patchwork.freedesktop.org/series/29564/</a> - patch series to fix conflict with OA NOA programming</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
