* KMS wrapper.
* - 3.0.0 - initial driver
* - 3.1.0 - allow reading more status registers (GRBM, SRBM, SDMA, CP)
* - 3.2.0 - GFX8: Uses EOP_TC_WB_ACTION_EN, so UMDs don't have to do the same
* at the end of IBs.
* - 3.3.0 - Add VM support for UVD on supported hardware.
+ * - 3.4.0 - Add AMDGPU_INFO_NUM_EVICTIONS.
