/*
 * 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.
 * - 3.5.0 - Add support for new UVD_NO_OP register.
 * - 3.6.0 - kmd involves use CONTEXT_CONTROL in ring buffer.
 * - 3.7.0 - Add support for VCE clock list packet
 * - 3.8.0 - Add support raster config init in the kernel
 * - 3.9.0 - Add support for memory query info about VRAM and GTT.
