For bwaves it is safe to ignore that.
change src/sim/syscall_emul.hh::ioctlFunc() to
switch (req) {
/*case OS::TIOCISATTY_:
case OS::TIOCGETP_:
case OS::TIOCSETP_:
case OS::TIOCSETN_:
case OS::TIOCSETC_:
case OS::TIOCGETC_:
case OS::TIOCGETS_:
case OS::TIOCGETA_:
case OS::TCSETAW_:
return -ENOTTY;
*/
default:
warn("Unsupported ioctl call: ioctl(%d, 0x%x, ...) @ \n",
fd, req, tc->pcState());
return -ENOTTY;
}
Then in arch/x86/linux/syscalls.cc modify:
/* 16 */ SyscallDesc("ioctl", ioctlFunc<X86Linux64>),
/* 54 */ SyscallDesc("ioctl", ioctlFunc<X86Linux32>),
