Raster order view

Abstract:

Systems, apparatuses, and methods for implementing raster order view enforcement techniques are disclosed. A processor includes a plurality of compute units coupled to one or more memories. A plurality of waves are launched in parallel for execution on the plurality of compute units, where each wave comprises a plurality of threads. A dependency chain is generated for each wave of the plurality of waves. The compute units wait for all older waves to complete dependency chain generation prior to executing any threads with dependencies. Responsive to all older waves completing dependency chain generation, a given thread with a dependency is executed only if all other threads upon which the given thread is dependent have become inactive. When executed, the plurality of waves generate a plurality of pixels to be driven to a display.
