hiwhy qemu does not provide NPTL support for x86 in user mode? is there any big hindrance behind it? I did a small experimentI make a program with fork system call and give its executable to qemu-x86_64 out put shows it does not create child. the I commented out this if block of linux-user/syscall.cif ((flags & ~(CSIGNAL | CLONE_NPTL_FLAGS2)) != 0) return -EINVAL;so that it can fork now as next line of code is thisfork_start(); ret = fork();now it started working, the child has created.if it is so simple then wat is the hurdle that original qemu code can not run fork'ed program?REGARDS
