  • Publication number: 20230290035
    Abstract: A system and method for performing graphics processing is provided. The system and method includes processing an allocation command for a buffer object; reserving processor address space for a data store of the buffer object with uncommitted physical memory in response to the allocation command including a null parameter, and reserving processor address space for a data store of the buffer object with committed physical memory in response to the allocation command including a non-null parameter.

  • Patent number: 11676321
    Abstract: A method and system for performing graphics processing is provided. The method and system includes storing stencil buffer values in a stencil buffer; generating either or both of a reference value and a source value in a fragment shader; comparing the stencil buffer values against the reference value; and processing a fragment based on the comparing the stencil buffer values against the reference value.
    Type: Grant

  • Patent number: 10699464
    Abstract: Methods for enabling graphics features in processors are described herein. Methods are provided to enable trinary built-in functions in the shader, allow separation of the graphics processor's address space from the requirement that all textures must be physically backed, enable use of a sparse buffer allocated in virtual memory, allow a reference value used for stencil test to be generated and exported from a fragment shader, provide support for use specific operations in the stencil buffers, allow capture of multiple transform feedback streams, allow any combination of streams for rasterization, allow a same set of primitives to be used with multiple transform feedback streams as with a single stream, allow rendering to be directed to layered framebuffer attachments with only a vertex and fragment shader present, and allow geometry to be directed to one of an array of several independent viewport rectangles without a geometry shader.
