Ubuntu Mate 16.04 2016-07-21 has no pvr_dri.so driver

There is no pvr driver. When I running a graphic software it show libGL error as follow.

===================== pi@bpi-iot-ros-ai:~$ glxinfo name of display: :0 libGL error: unable to load driver: pvr_dri.so libGL error: driver pointer missing libGL error: failed to load driver: pvr display: :0 screen: 0 direct rendering: Yes server glx vendor string: SGI server glx version string: 1.4 server glx extensions: …

I scan all files in the image but cannot found the pvr_dri.so file.

Could anyone please point me where can I download this file.

Thanks.
