    Abstract: Apparatus and method for acceleration data structure refit. For example, one embodiment of an apparatus comprises: a ray generator to generate a plurality of rays in a first graphics scene; a hierarchical acceleration data structure generator to construct an acceleration data structure comprising a plurality of hierarchically arranged nodes including inner nodes and leaf nodes stored in a memory in a depth-first search (DFS) order; traversal hardware logic to traverse one or more of the rays through the acceleration data structure; intersection hardware logic to determine intersections between the one or more rays and one or more primitives within the hierarchical acceleration data structure; a node refit unit comprising circuitry and/or logic to read consecutively through at least the inner nodes in the memory in reverse DFS order to perform a bottom-up refit operation on the hierarchical acceleration data structure.

    Abstract: An apparatus to facilitate asynchronous execution at a processing unit. The apparatus includes one or more processors to detect independent task passes that may be executed out of order in a pipeline of the processing unit, schedule a first set of processing tasks to be executed at a first set of processing elements at the processing unit and schedule a second set of tasks to be executed at a second set of processing elements, wherein execution of the first set of tasks at the first set of processing elements is to be performed simultaneous and in parallel to execution of the second set of tasks at the second set of processing elements.

    Abstract: One embodiment provides a graphics processor comprising a hardware graphics rendering pipeline configured to perform multisample anti-aliasing, the hardware graphics rendering pipeline including pixel processing logic to determine that each sample location of a pixel of a multisample surface is associated with a clear value and resolve a color value for the pixel to a non-multisample surface via a write of metadata to indicate that the pixel has the clear value. The resolve can be a stenciled resolve that automatically bypasses execution of a pixel shader for pixels having clear color data.

    Abstract: Embodiments are generally directed to GPU mixed primitive topology type processing. An embodiment of an apparatus includes one or more processor cores; and a memory to store data for graphics processing, wherein the one or more processing cores are to generate in the memory a vertex buffer to store vertex data for a mesh to be rendered and an index buffer to index the vertex data stored in the vertex buffer, the index buffer being structured to include index data for multiple primitive topology types. The one or more processor cores are to process the index data for the plurality of primitive topology types from the index buffer and fetch vertex data from the vertex buffer; and are to set up each primitive topology type of the plurality of primitive topology types for processing in a single draw operation.
