  • Patent number: 10776235
    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.

  • Publication number: 20200219430
    Abstract: Methods and systems for multiple-buffered display rendering without the use of hardware or software interrupts. In a first repeating process, a processor writes data for a frame a selected frame buffer and, upon completion of the frame, a swap buffer signal is transmitted. In response to the swap buffer signal, the GPU updates a memory register of the display controller to indicate that the selected frame buffer can be used in the next display synchronization interval. In a separate repeating process, the display controller monitors memory register and, in a display synchronization interval, identifies the frame buffer to use for display.

  • Patent number: 10540738
    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.

  • Publication number: 20170116702
    Abstract: A system, method, and computer-readable medium are provided for translating OpenGL API calls to operations in a Vulkan graphics driver using an OpenGL-on-Vulkan driver architecture. An OpenGL-on-Vulkan driver receives an OpenGL context and render function, translates an OpenGL format to a Vulkan format, creates a Vulkan object and sets a Vulkan state, and generates a Vulkan command buffer corresponding to the OpenGL render function.
