--- Comment #3 from Jason Ekstrand <jason at jlekstrand.net> ---
The real issue here is that we have lots of GPU allocations that don't come in
through libc so valgrind doesn't know about them.  Valgrind then complains
every time we touch these allocations from the CPU even though it's totally
valid.  If you install the valgrind-devel package and build mesa yourself, it
should detect valgrind and add hints to the driver to help valgrind out errors
will go away.
