摘要： 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.

摘要： 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.

摘要： 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.

摘要： Systems and method for triple buffering of a graphics display without use of interrupts using at least two command buffers that are capable of operating asynchronously. A first command buffer generally contains commands, which, when executed, write frame data to a plurality of frame buffers in round-robin fashion. A second command buffer, which is executed asynchronously to the first command buffer, contains commands to handle waiting for frames to be completed, handle display timing (e.g., display synchronization interval, such vertical sync or vertical blanking intervals), and to cause the display controller to display the correct frames.
