43 * - 2.0.0 - initial interface
44 * - 2.1.0 - add square tiling interface
45 * - 2.2.0 - add r6xx/r7xx const buffer support
46 * - 2.3.0 - add MSPOS + 3D texture + r500 VAP regs
47 * - 2.4.0 - add crtc id query
48 * - 2.5.0 - add get accel 2 to work around ddx breakage for evergreen
49 * - 2.6.0 - add tiling config query (r6xx+), add initial HiZ support (r300->r500)
50 * 2.7.0 - fixups for r600 2D tiling support. (no external ABI change), add eg dyn gpr regs
