I definitely agree it should come soon. I realize the QEMU community could 
start this effort rather easily by developing a machine and then porting 
software to it. I'm thinking something easy we could do is take the IBM PC 
standard and apply it with a RISC-V CPU. Hardware vendors could then take that 
emulated machine and turn it into a real machine. Linux distros could then be 
made to run on this platform. The future looks exciting for this CPU.
