Roberto,

You can run the benchmark by doing the following:

a. sudo apt-get install glmark2
b. Then open a command prompt and run glmark2

It seems pretty stable so far (other then the artifacts on the GDM login
screen) but I am having one issue where UVD (for hardware acceleration of
video) is not initializing and I'm not sure why. Initially I had just
updated the TURKS radeon firmware but it was complaing about needing SUMO
for the uvd so I copied that as well and re-installed the kernel but no
luck in getting UVD to work.

If you want to try using the latest stuff yourself here I used the basic
instructions here
http://askubuntu.com/questions/324733/how-to-enable-the-radeon-dynamic-power-management-feature-in-ubuntu-13-04.
Below are my steps in short form

1. Boot the computer in Ubuntu with the PMD NOT attached
2. Copy the latest radeon firmware files into /lib/firmware/radeon, you
need the TURKS and SUMO firmware (SUMO for UVD). Backup your old firmware
first
3. Install the latest kernel, I used the instructions here
http://ubuntuhandbook.org/index.php/2013/09/linux-kernel-3-11-released-install-upgrade-in-ubuntu-13-0412-04/
4. Update grub to include the radeon.dpm=1 parameter
5. Reboot, if you want the latest mesa 9.2 which helps performance a bit
install the xorg-edgers ppa
6. Make config changes necessary to detect PMD attached and use radeon
driver as per here
http://forum.notebookreview.com/sony/702034-sony-vaio-z-2012-review-linux-perspective.html

And that's it, but like I said I'm not swearing this setup is stable at
this point as I just started playing with it yesterday. Also, I tried
running the glmark2 against the Intel card and it gave me a segfault on one
of the later tests.

I will also say while this setup feels somewhat faster then previously plus
you get the benefit of power management, the radeon card in the PMD is
still slower then the built in intel graphics. I used to think it was just
an open source driver issue but at this point I'm not too sure, I'm
wondering if it has something do with the way Linux manages PCI as the PMD
basically extends the PCI system through light peak/thunderbolt. I just
don't know enough to determine this though.
