Virtual graphics device driver

A method, comprising:

• routing, using graphics driver software, first function calls received from a framework to a first graphics processing unit (GPU) of an electronic device for execution of the first function calls by the first GPU;
• rendering an image for display on a display of the electronic device via the first GPU by providing image data to the display from a first frame buffer when the first function calls are routed to the first GPU, wherein the provision of the image data to the display from the first frame buffer is provided via a frame buffer application programming interface through the graphics driver software;
• determining, using the graphics driver software, whether to switch rendering from the first GPU to a second GPU, wherein when it is determined to switch rendering from the first GPU to the second GPU;
• in response to the determination to switch and using the graphics driver software, routing second function calls received from the framework to the second GPU of the electronic device for execution of the second function calls by the second GPU, wherein the second function calls are subsequent to the first function calls;
• and
• rendering a second image for display on the display by providing the image data to the display from a second frame buffer when the second function calls are routed to the second GPU, wherein the provision of the image data to the display from the second frame buffer is provided via the frame buffer application programming interface through the graphics driver software.

A non-transitory tangible machine-readable storage medium comprising instructions for:

• determining to switch graphics function calls from a first graphics processing unit (GPU) to a second GPU using graphics driver software, wherein the graphics driver software determines when to switch the graphic function calls;
• receiving, at the graphics driver software, a function call based at least in part on a type of function call;
• routing, using the graphics driver software, the function call to a selected one of the first GPU or the second GPU for processing therein;
• providing image data to a display from a first frame buffer when the graphics function calls are routed to the first GPU, wherein the provision of the image data to the display from the first frame buffer is provided via a frame buffer application programming interface through the graphics driver software;
• and
• providing the image data to the display from a second frame buffer when the graphics function calls are routed to the second GPU, wherein the provision of the image data to the display from the second frame buffer is provided via the frame buffer application programming interface through the graphics driver software.
