[Qemu-devel] [Bug 902413] Re: qemu-i386-user on ARM host: wine hangs/spins when trying to run anything

["Pierre-Loup A. Griffais" <902413@bugs.launchpad.net>]

Understood, thanks a lot for the pointers. From a quick skim it doesn't
look like I'm directly running into any of these ARM host issues (yet).
I'm hopeful that the i386 target will get increasing attention in the
future as ARM devices get more widespread after x86 was the standard for
so long. Out of curiosity, is the amd64 target in any better shape?

  qemu-i386-user on ARM host: wine hangs/spins when trying to run
  anything

Bug description:
  With qemu built from git from 217bfb445b54db618a30f3a39170bebd9fd9dbf2
  and configured with './configure --target-list=i386-linux-user
  --static --interp-prefix=/home/pgriffais/natty-i386/', trying to run
  wine 1.3.15 from an Ubuntu 11.04 chroot results in hangs. If I run an
  i386 emulated wineserver, wineserver hangs in:

  While wine hangs in:

  However if I build wineserver 1.3.15 natively for ARM and run it on
  the host while wine is emulated, I get the following:

  root@tiberiusstation:/home/ubuntu# ./natty-i386/usr/bin/wine notepad
  Unsupported ancillary data: 1/2
  Unsupported ancillary data: 1/2
  Unsupported ancillary data: 1/2
  err:process:__wine_kernel_init boot event wait timed out

  I assume the last one is due to wineboot.exe hanging. The main wine
  process hangs in there:

  Running the same version of wine through qemu-user-i386 running on an
  i386 host works fine with both wineserver and wine being emulated;
  that's the result I'm trying to achieve.
