DRI3 support is built into driver.

Intel DDX defaults currently to DRI2, you can set DRI3 default in X config:
--------------------------
Section "Device"
Driver "Intel"
Identifier "Intel"
Option "DRI" "3"
EndSection
--------------------------
If you run the application with LIBGL_DEBUG=verbose, Mesa will tell which DRI
version is used:
--------------------------
$ LIBGL_DEBUG=verbose glxgears
libGL: Using DRI3 for screen 0
--------------------------</pre>
