Abstract
In some examples, a non-transitory machine readable medium storing instructions executable by a processor to store display information in a private memory hidden from an operating system (OS), and divisibly virtualize a contiguous planar display into a first area as a main display and a second area as a second display separate from the main display, where the continuous planar display is divisibly virtualized responsive to exposure of the display information to the OS or the display information being directly provided to a graphics processing unit (GPU).
Claims16
A non-transitory machine readable medium storing instructions executable by a processor to:
- store display information in a private physical memory hidden from an operating system (OS);
- and
- divisibly virtualize a contiguous planar display into a first area as a main display and a second area as a second display separate from the main display, wherein the continuous planar display is divisibly virtualized responsive to:
- exposure of the display information in the private physical memory to the OS;
- or
- the display information being directly provided from the private physical memory to a graphics processing unit (GPU).
A system, comprising:
- a display device having a contiguous planar display and a first interface;
- a computing device having a second interface to couple with the first interface of the display device, the computing device including an operating system (OS), a private random-access memory (RAM) hidden from the OS, and a processor, the processor to:
- store display information in the private RAM;
- and
- divisibly virtualize the contiguous planar display into a first area of the planar display as a main area and a second area isolated from the main area, wherein the continuous planar display is divisibly virtualized responsive to both an input to activate dual display mode and:
- exposure of the display information in the private RAM to the OS;
- or
- the display information being directly provided to a graphics processing unit (GPU).
A computing device comprising:
- a graphics processing unit (GPU);
- an interface to couple to a display device having a contiguous planar display
- a physical memory including a private frame buffer and a public frame buffer;
- and
- processor to:
- store display information in the private frame buffer;
- and
- responsive to an input to activate dual display mode:
- divisibly virtualize the contiguous planar display into a first area of the planar display as a main area and a second area isolated from the main area, wherein the continuous planar display is divisibly virtualized responsive to:
- selective exposure of the display information in the private frame buffer to the OS when hidden mode is inactive;
- or
- the display information being directly provided from the private frame buffer to the GPU when hidden mode is active.
