Abstract: Methods and systems for monitoring the integrity of a graphics processing unit (GPU) are provided. The method comprises the steps of determining a known-good result associated with an operation of the GPU, and generating a test image comprising a test subject using the operation of the GPU, such that the test subject is associated with the known-good result. The test image is written to video memory, and the known-good result is written to system memory. Subsequently, the test subject from the test image is transfered from video memory to system memory. The test subject in the system memory is compared with the known-good result in system memory. If the test subject does not match the known-good result, then a conclusion is drawn that the integrity of the GPU has been compromised.

Abstract: Methods, systems, and computer-readable media for rendering graphics using a graphics pipeline for emulating a fixed-function graphics pipeline, including selecting a first pre-compiled shader chunk from a set of pre-compiled shader chunks, selecting at least one second pre-compiled shader chunk from the set of pre-compiled shader chunks, and, concatenating the first shader chunk with the at least one second shader chunk, wherein each shader chunk corresponds to a fixed-function graphics function.

Abstract: Methods, systems, and computer-readable media for monitoring a graphics processing unit (GPU) of a host computer system, including providing at least one test seed and at least one subsystem command to the GPU; receiving at least one test result from the GPU in response to providing the at least one test seed and at least one subsystem command to the GPU; and if the at least one test result does not correspond to at least one expected result, identifying the GPU as being in an undesired state. The subsystems to be tested may be a subset of all subsystems. The determination of subsystems to be tested may be determined in real-time, based on graphical application instructions. The subsystems to be tested may also be pre-determined.
