Symmetry: reserve_fence, unreserve_fence. We need a safeguard here so that the host is able to always able allocate to allocate a fence for the display engine. (That requirement should be quite soft for modern hw, nevertheless it should be in the design to prevent overuse from leading to an unusable system.) -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
