+[Vulkan](https://www.khronos.org/vulkan/) Driver written in
+Rust that uses LLVM for code generation. Kazan will use Optimised 3D
+instructions specifically designed and added to the Libre RISC-V M-Class
+SoC, yet Kazan itself may still be used (unoptimised) on other hardware.
+
+The performance target for Kazan on the Libre RISCV SoC is a very modest
+mobile-class level (1280x720 25fps, 100MPixels/sec, 30MTriangles/sec,
+5-6GFLOPs), whilst the power budget is very tight: under 2.5 watts in 28nm.
+With RISC-V being 40% more power efficient than x86 or ARM, this is
+very reasonably achievable.
