<p class="MsoNormal">Not sue if this is right direction, I think usermode wants all synchronizations to be explicit. Implicit sync often confuses people who don’t know its history. I remember Jason from Intel is driving explicit synchronization through the

<p class="MsoNormal">This enables a full pipeline sync for implicit sync. It's Christian's patch with the driver version bumped. With this, user mode drivers don't have to wait for idle at the end of gfx IBs.<o:p></o:p></p>
