[Qemu-devel] qemu user x86 working?

[Andi Kleen <ak@linux.intel.com>]

Hi,

Is the linux-user qemu for x86-64/i386 supposed to work?

For example running it with a simple hello world on FC14 in gdb:

/home/ak/tsrc/hello: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, not stripped

[Thread debugging using libthread_db enabled]
ERROR: ioctl(SNDCTL_DSP_MAPINBUF): target=0x80085013 host=0x80105013
ERROR: ioctl(SNDCTL_DSP_MAPOUTBUF): target=0x80085014 host=0x80105014

Program received signal SIGSEGV, Segmentation fault.
0x000000006021f854 in static_code_gen_buffer ()
(gdb) disp/3i $pc

   0x6021f857 <static_code_gen_buffer+162663>:  mov    0x28(%r14),%rbx
   0x6021f85b <static_code_gen_buffer+162667>:
    add    $0xffffffffffffff88,%rbx
(gdb) p $rbx
$2 = 0

I tested a few releases back, 0.13 and also 14-rc0 and they 
all segfault, although they are not all in the same place.
The qemu-user shipped by Fedora also seems to have the same problem.

Is this a known issue or am I doing something obviously wrong?

Thanks,
-Andi
