<div>The spec of DTV SoC was release. I got the HW spec. And I found the design was not consider about "shader".</div>
<div>Our HW architecture was a VG pipe line, almost like <a href="http://www.khronos.org/assets/uploads/apis/openvg_pipeline1.jpg">http://www.khronos.org/assets/uploads/apis/openvg_pipeline1.jpg</a></div>
<div>Is this means that it is not make sense to write a Gallium driver for GL/VG state tracker?<br></div>
