how to enable hyperZ on radeon hd 5000 series?

by

I have surfed around the web to enabling hyperZ by adding this parameter R600_DEBUG=hyperz, but where I must put it? Is it at /etc/default/grub ?

My Card : Ati Mobility Radeon HD5650

Answer

After asking on phoronix forums, just put

R600_HYPERZ=1

in /home/$USER/.profile
