# Test the implementation of i386_get_ldt() and i386_set_ldt() for 32 bit
# processes on amd64 by running wine and mplayer with a 32 bit codec.
# This is not a test script, but more of a howto document.

This are notes of how to perform the test.
First of all you will need a i386 jail on amd64. This could be build like
this:
cat > jailbuild.sh <<EOF
#!/bin/sh
jail=/var/tmp/jail2 # Change this
mount | grep $jail | grep -q devfs && umount $jail/dev
here=`pwd`
chflags -R 0 $jail
rm -rf $jail
mkdir -p $jail
cd /var/tmp/deviant2 # You will need to change this!
make -j4 TARGET=i386 TARGET_ARCH=i386 DESTDIR=$jail world
make TARGET=i386 TARGET_ARCH=i386 DESTDIR=$jail distribution
mount -t devfs devfs $jail/dev
cp /etc/fstab /etc/hosts /etc/resolv.conf $jail/etc
cp /boot/kernel/kernel $jail/boot/kernel
EOF
Before changing to the jail you may need these files:
- Fetch the Firefox i386 installer. (http://www.mozilla.com)
- Fetch a clip for a win32 codec:
ftp http://www.jhepple.com/support/SampleMovies/Real_Media.rm
and place these in for examle $jail/root
Chroot to /var/tmp/jail /bin/sh
1) Install wine. For example by "UNAME_m=i386 pkg_add -r wine"
3) Run wine on the Firefox installer.
The mplayer test:
It would seem that the default build of mplayer does not contain
the i386 codec, so you have to build mplayer your self with option
"Enable win32 codec set on the IA32 arch".
Remember to set the environment variable UNAME_m to "i386".
cat > mplayer.sh <<EOF
#!/bin/sh
export DISPLAY=<your display host goes here>:0
while true;do
pos=100
for i in `jot 5`; do
mplayer -vc rv40win -geometry $pos:$pos /root/samples/Real_Media.rm < \
/dev/null > /dev/null 2>&1 &
pos=$((pos + 50))
done
for i in `jot 5`; do
wait
done
done
EOF
