Hi, sorry if I misunderstood everything... In the file src/gallium/drivers/nouveau/nv30/nv30_screen.c there is loans of PUSH_DATA which is basically *push->curr = data; I'm thinking that somehow push->curr is the bo->map = drm_mmap(...) that is called in nouveau_bo_map. But I cannot see how they are linked... Because when nouveau_bo_map calls nouveau_bo_wait push =

Hi guys, I'd like to start a new thread about explicit fence synchronization. This time with a Nouveau twist. :-) First, let me define what I understand by implicit/explicit sync: Implicit synchronization * Fences are attached to buffers * Kernel manages fences automatically based on buffer read/write access Explicit synchronization * Fences are passed around independently * Kernel takes
