This is modified version of official xv6-public version. As it was stated that "The main purpose of xv6 is as a teaching operating system for MIT's 6.S081, so we are more interested in simplifications and clarifications than new features" so no PR will be made through this fork.
This version is slightly modified and tested on
- OS: Garuda Linux
- Kernel: 5.15.12-zen1-1-zen
- Shell: fish-3.3.1
- gcc/g++: 11.1.0
Case 1: make qemu "error: writing 1 byte into a region of size 0"
two lines added before and after *line 1461: lastaddr = 99; in usertests.c
#pragma GCC diagnostic ignored "-Wstringop-overflow"
*lastaddr = 99;
#pragma GCC diagnostic popCase 2: qemu hangs on "Booting from hard disk..."
this problem occurs specially on arch linux though it is quite common for other distros also. See PR#155. to solve this problem Makefile was slightly modified.
