Back in 2012 (commit1e7776ca2b- egl: Remove bogus invalidate code.) the loader use of invalidate() was purged as "bogus". One of the factors defining that statement was the lack of the loader-side invalidate extension - __DRI_USE_INVALIDATE. Since then the commit was reverted (commiteed0a80137- egl: Restore "bogus" DRI2 invalidate event code.), always performing the driver invalidate call, although the loader was never updated to expose the extension. Do so allowing the driver to do fine grained tuning.
