[needs-packaging] pvr sgx driver and kernel module for Pandaboard

[Ricardo Salveti]

TI released the PowerVR SGX 3D drivers for Omap 4 (Pandaboard) under a redistributable license.

The original package is provided at https://launchpad.net/~tiomap-dev/+archive/release?field.series_filter=precise, and this bug is a request to include the packages at the Ubuntu archive as well, so we can enable Unity 3D for Pandaboard without enabling any external PPA.

The DKMS kernel module package needs to go to universe, and the userspace libraries and X11 driver to multiverse.

This bug will also be used to document the feature freeze exception for Precise.

I'll be uploading the packages to a PPA and update the bug with the appropriate links.

Tested and validated it with a Pandaboard 4430 and 4460, and I'm able to fully use OpenGL ES2.0 based applications after installing the driver and restarting the X11 server.

To have the driver working without forcing a X11 config file, bug 959928 also needs to be fixed (fixed package available at the PPA as well).

[Oliver Grawert (ogra)]

both packages were uploaded now and should sit in the NEW queue until an archive admin reviews and lets them through.

[Ricardo Salveti (rsalveti)]

Per request over IRC from Adam, I updated the packaged following the guidelines described at https://wiki.ubuntu.com/X/EGLDriverPackagingHOWTO, with the following changes:
 - Same package for both libraries and dkms module
 - Libraries using update-alternatives instead of replaces/conflicts
 - Main header files now provided by the mesa package, without conflicts
 - Package based on the fglrx and nvidia drivers

Now we're just missing the integration with jockey, as I still need to check in details how we'll be supporting a platform device (we don't have it identified by neither pci or usb buses).

Should be good enough to hit the archive already.

The pvr-omap4 package has been accepted into precise, so I believe this issue is resolved.
