I think we have a gap that after splitting the drm-intel-next pull requests= into two the drm-intel/for-linux-next branch is now missing material from drm-intel/drm-intel-gt-next. I think a simple course of action might be to start including drm-intel-gt-= next in linux-next, which would mean that we should update DIM tooling to add extra branch "drm-intel/gt-for-linux-next" or so. Which specific patches are missing in this case? Regards, Joonas
