LIBVA_SUPPORT in sdk 2014

Hi,
1. Download new Media SDK 2014 for Clients， See code for vaapi from samples. Where can I find these files ?

#if defined LIBVA_SUPPORT
#include "vaapi_allocator.h"
#include "vaapi_device.h"
#endif

2.  use mediasdk_sys_analyzer.exe says 1.8 HW not support
I use CPU:    Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
so, which cpu should i update to ? 

Please Help.

Regards,

LK
