Re: [gem5-users] syscall ioctl unimplemented

[zpwu]

Hi,

After changing the code as you described, I still get the same errors.  
Do I need to rebuild the system with scons again?

Thanks

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>),

You need to hook-up the system call in
src/arch/x86/linux/syscalls.cc and ultimately you'll need to look at the
implementation of the ioctl call in src/sim/syscall_emul.* and see if it
does something sensible for what this benchmark is trying to use it for.
Most of the time it's just the c library trying to decide if the
terminal is a TTY and these can be safely ignored.

Hi all,

I tried to run the
bwaves benchmark from SPEC 2006 in X86_SE mode and
i get the
following error:

**** REAL SIMULATION ****
info: Entering event
queue @ 0. Starting simulation...
warn: instruction 'fnstcw_Mw'
unimplemented
warn: instruction 'fldcw_Mw' unimplemented
fatal:

[unimplementedFunc:build/X86_SE/sim/syscall_emul.cc, line 83]

Did anyone else get this error as well? Anyone
know how to fix this?

Thanks
