[SNIP] I'm only interested in the case of shared buffers. And for those you _do_ pessimistically assume that all access must be implicitly synced. Iirc amdgpu doesn't support EGL_ANDROID_native_fence_sync, so this makes sense that you don't bother with it.
See flag AMDGPU_GEM_CREATE_EXPLICIT_SYNC.
That's for radv. Won't be enough for EGL_ANDROID_native_fence_sync, because you cannot know at buffer allocation time how the fencing will be done in all cases. -Daniel
