摘要： A method for using an EGL driver to create a renderable surface for an OpenGL API is provided. The EGL driver and the OpenGL API can be used with a Vulkan graphics driver, a memory, at least one processor, and a module stored in the memory including computer instruction code that is executable by the at least on processor. The method includes creating an EGL display structure; initializing the EGL display structure by querying the Vulkan driver for attributes of a physical display; choosing an EGL configuring matching the provided attributes; and creating the EGL surface. A non-transitory computer readable medium having an EGL driver with computer instruction code that is executable by a processor to create a renderable surface for an OpenGL API is also provided.

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 transferred 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 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.

摘要： Multiple-buffered display rendering without the use of hardware or software interrupts. Five buffers can be used: two designated as front buffers and three designated as back buffers. Initially, all five buffers may be targeted for rendering in round robin fashion. As frames are rendered and processed by the graphics device, a frame index counter may be updated to track the ordinal number of each frame rendered by the GPU.

摘要： 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.

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.
