+ * /dev/verite3d - expierimental 3D interface for veritefb(4)
+ *
+ * By design, it is completely independent of wsdisplay(4). It supports
+ * one exclusive client - opening the device stops the 2D microcode.
+ * Closing the device stops the 3D microcode and restores the console,
+ * in the state it was left behind.
+ *
+ * The client supplies its own RISC microcode (V3D_INIT) and owns
+ * the FIFO command stream. The kernel moves bytes (DMA) and tracks VRAM,
+ * but does NOT interpret the command stream. That is responsibility of
+ * the microcode (on the hardware side) and the userland process.
