Abstract
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, the tile count of tiles of a current primitive that have been coarse rasterized is saved in a backing store. After storing the tile count, the one or more primitives of a second context are rasterized. After the second context is served, the coarse rasterization of the current primitive of the previous context is rerun without output until the tile corresponding to the stored tile count is coarse rasterized. Thereafter, rasterization of the current primitive of the first context from the next tile beyond the stored tile count is continued until rasterization is completed or another interrupt is received and the above described process is repeated.
