Abstract:
Exemplary methods, apparatuses, and systems receive a command from a program to render graphics data on a display device, transmit the command to a graphics processing unit (GPU), and transmit a readback request to the GPU. Upon receiving a response to the readback request from the GPU, the program is alerted that the command has been transmitted to the GPU. The response to the readback request is a pointer to a memory location at which the GPU has written rendered frame data representing the command. In response to receiving notification of a failure of the GPU, the rendered frame data written in response to the readback request and any additional commands to render the additional graphics requests received subsequent to the transmission of the readback request are transmitting to the GPU upon recovery from the failure, or to another GPU.
