   1 The Libre RISC-V M-Class is a RISC-V chip that is libre-licensed to the
   2 bedrock. It is a low-power, mobile-class, 64-bit Quad-Core SoC at a
   3 minimum 800mhz clock rate, suitable for tablet, netbook, and industrial
   4 embedded systems. Full source code and files are available not only
   5 for the operating system and bootloader, but also for the processor,
   6 its peripherals and its 3D GPU and VPU.

  10 Onboard the Libre RISC-V M-Class is the
  11 [Kazan](https://salsa.debian.org/Kazan-team/kazan) GPU, a
  12 libre-licensed, software-rendered
  13 [Vulkan](https://www.khronos.org/vulkan/) Driver written in
  14 Rust that uses LLVM for code generation.  Kazan will use optimised 3D
  15 instructions specifically designed for and added to the Libre RISC-V M-Class
  16 SoC, yet Kazan itself may still be used (unoptimised) on other hardware.

  18 The performance target for Kazan on the Libre RISCV SoC is a very
  19 modest mobile-class level (1280 x 720 25 fps, 100 Mpixels/sec, 30
  20 Mtriangles/sec, 5-6 GFLOPs), whilst the power budget is very tight
  21 (under 2.5 watts in a 28 nm process).  With RISC-V being 40% more
  22 power efficient than x86 or ARM, this is very reasonably achievable.
