Xv6: A modern, x86 reimplementation of 6th Edition Unix

The x86 version of xv6 is no longer updated, the last updates took place about 7 years ago. Current xv6 supports RISC V in qemu, there are also ports to real RISC V devices (Kendryte/Canaan K210 by Huazhong University of Science and Technology, Allwinner D1 and StarFive JH7110 by me) and FPGA implementations (by Michael Schröder).
