More Information
Summary:Techniques for handling an interrupt in the rasterizer, in accordance with embodiment of the present technology, start with rasterizing one or more primitives of a first context. If an interrupt is received, state information of the rasterizer is saved in a backing store after coarse rasterizing a given tile. After storing the raster state information, the one or more primitives of a second context are rasterized. After the second context is served, the raster state information of the first context is restored and rasterization of the one or more primitives of the first context is restarted.
