[Mesa-dev] [PATCH 5/7] i965: use _mesa_geometry_width/height/layers/samples for programming geometry of framebuffer to GEN

kevin.rogovin at intel.com kevin.rogovin at intel.com
Thu Apr 23 23:59:08 PDT 2015


From: Kevin Rogovin <kevin.rogovin at intel.com>

To prepare for i965 to support ARB_framebuffer_no_attachment, use
the convenience functions mesa_geometry_width/height/layers/samples
to specify the geometry of the render target surfaces to the GPU.
