Finding SSSE3 Instructions in a Binary

I came up with this using http://en.wikipedia.org/wiki/SSSE3#New_Instructions 

objdump --disassemble-all <binary> | grep " \(psign[bwd]\|pabs[bwd]\|palignr\|pshufb\|pmulhrsw\|pmaddubsw\|phsub[wd]\|phsubsw\|phadd[wd]\|phaddsw\) "

Emulating Missing Instructions in the Kernel 

arjan: you can emulate instructions your cpu does not have quite well
ali1234: i didn't know there was such a patch... link please?
arjan: either via a kernel hack or an ld preload library
arjan: http://lkml.indiana.edu/hypermail/linux/kernel/0206.3/0631.html  <-- old kernel hack that google found for me
arjan: doing it as ld preload isn't too hard .. SIGILL is sent when an instruction is executed that the cpu does not grok
ali1234: ah so you don't know that it exists specifically for ssse3?
arjan: for ssse3? not that I know of
arjan: but you could add the ssse3 instructions if you want
arjan: shouldn't be too hard

Notes on Setting Up Private OBS (WIP)

Install OBS Appliance inside a VM

VM Config

Configure VM with two virtual disks. Primary 20GB for the appliance image and /home, secondary 100GB for OBS LVM partitions.

Install Appliance

Boot it with your favourite Linux live CD and write the appliance image to the virtual disk: 

wget http://download.opensuse.org/repositories/openSUSE:/Tools/images/obs-server.x86_64-2.0.5-Build1.8.raw.bz2
bunzip2 -c obs-server.x86_64-2.0.5-Build1.8.raw.bz2 > /dev/sda

Configure LVM

Use fdisk to make one big partition on /dev/sdb, type 8e: 

fdisk /dev/sdb

Make LVM partition for server: 

pvcreate /dev/sdb1
vgcreate "OBS" /dev/sdb1
lvcreate -L 70G -n "server" /dev/OBS
vgscan
mkfs /dev/OBS/server

For cache: 

lvcreate -L 20G -n "cache" /dev/OBS
vgscan
mkfs /dev/OBS/cache

For two workers: 

lvcreate -L 4G -n "worker_root_1" /dev/OBS
lvcreate -L 512M -n "worker_swap_1" /dev/OBS
lvcreate -L 4G -n "worker_root_2" /dev/OBS
lvcreate -L 512M -n "worker_swap_2" /dev/OBS
vgscan
mkfs /dev/OBS/worker_root_1
mkfs /dev/OBS/worker_root_2

Now eject the virtual CD device and reboot the VM into the appliance system.
