A switchable graphics management scheme, which uses performance/watt information of both the iGPU/dGPU along with system real-time resources like SoC (system-on-chip) thermal, system power budgets to decide on the right GPU for rendering tasks. The scheme uses this threshold power point information along with system resources to determine the optimized GPU for tasks rendering for all applications and use cases. As such, the scheme of adapts to each system design based on capabilities of that specific system.

Apparatus and method to improve switchable graphics system performance and energy consumption based applications and real-time system power/thermal budgets

Two extended embedded Display Port displays may be enabled by using a single set of panel power sequencing (PPS) signals from a chipset to enable the two embedded Display Port panels. To enhance the user experience, the backlight module brightness is controlled by making use of a pin available on a system on a chip (SOC) and modification of drivers. This helps to save power when only one panel is used. When both panels are used simultaneously, power savings can be achieved by using backlight control signals.

Enabling a chipset that supports a single display to support dual display

In some embodiments, power may be temporarily removed from a first portion of a computer system (such as a display), and that power redirected to a second portion (such as a processor or System on a Chip), so that extra performance may be obtained from the second portion without exceeding the power budget for the system. If the first portion is a display, the time period of removed power may be short enough that the absence of luminance during that time period will not be noticeable to the human vision system. In a similar embodiment, power may be delivered to the first portion using pulse width modulation, using the time between pulses to redirect power to the other portion.
