I tried to avoid having to track the write for every VMA by only tracking writes to the ggtt. However, for the purposes of frontbuffer tracking this is insufficient as we need to invalidate around writes not just to the the ggtt but all aliased ppgtt views of the framebuffer. By moving the critical section to the object and only doing so for framebuffer writes we can reduce the tracking even further by only watching framebuffers and not vma. Signed-off-by:
