Bug Description

At https://launchpad.net/~tiomap-dev/+archive/omap-trunk you can find the PVR libs package (pvr-omap4) and also the PVR kernel module one (pvr-omap4-kernel).

The kernel module is a dkms package, and to be able to build and load the module some additional patches adding SGX is required.

I merged the needed patches and the config changes on top of linaro's kernel at https://gitorious.org/ubuntu-experimental/linaro-kernel-natty/commits/linaro-sgx. With these patches I'm able to build the PVR kernel module and use the GLES acceleration just fine.

Will be publishing the kernel debs for testing once the build is done.

Kernel deb file available at http://people.canonical.com/~rsalveti/775714/

Once you installed the debs, just enable omap-trunk PPA and install the pvr-omap4 package, it should build the kernel module and install the SGX libraries.

Then load X and run es2gears, you should be able to see the demo working fine, accelerated with GLES.
