The host1x hardware found on Tegra194 is mostly backwards compatible with the version found on Tegra186, with the notable exceptions of the increased number of syncpoints and mlocks. In addition, some rarely used features such as syncpoint wait bases were dropped and some registers had to move around to accomodate the increased number of syncpoints.
