Bug description:
[Impact]
* Right now in quantal the mesa package links a static copy of libgallium
and libdricore into every driver, resulting in an enormous size.
* This does not fit on the precise LTS cd, so a sru has been made for
mesa-lts-quantal where 2 additional patches have been enabled to re-enable the
patches to build libgallium and libdricore shared.
* Currently this is carried as a delta for mesa-lts-quantal vs mesa, but the
savings make sense for normal quantal too, else every time mesa-lts-quantal
gets updated those patches have to be re-applied again.
[Test Case]
* Quite easy to check, ls -l /usr/lib/*/dri/ and check for size, and whether
they're linked against libgallium and libdricore.
* It should be around 11 mb, but currently is around 36 mb or more.
* Additional care has to be taken that nothing will break, so manually trying
a simple opengl program on llvmpipe, i915, radeon and nouveau is recommended.
The stderr output from "LIBGL_DEBUG=verbose glxinfo" is good enough for this
purpose, and that will tell you if the driver succesfully loaded or not. I can
verify this on my laptops easily for those drivers.
[Regression Potential]
* mesa-lts-quantal and the mesa package from raring already have this
change, so the chance of regressions is not deemed to be high. mesa-lts-quantal
is a repackaging of the current package in quantal for precise.
* As part of the verification process, piglit will be run and watched for
regressions.
* Any failure will most likely manifest itself by failing to load the dri
driver, so expected failure mode is compiz failing to start.
[Other Info]
* Will also result in a new upload of mesa-lts-quantal to precise, for MRE
version bump to 9.0.2, and to stay in sync to quantal.
