   1 Libre RISC-V M-Class
   2
   3 A 100% libre RISC-V + 3D GPU chip for mobile devices
   4
   5 The Libre RISC-V M-Class is a RISC-V chip that is libre-licensed to the
   6 bedrock. It is a low-power, mobile-class, 64-bit Quad-Core SoC at a
   7 minimum 800mhz clock rate, suitable for tablet, netbook, and industrial
   8 embedded systems. Full source code and files are available not only
   9 for the operating system and bootloader, but also for the processor,
  10 its peripherals and its 3D GPU and VPU.

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

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