Dependencies

|
|
This extension is written against the wording of the EGL 1.4
|
|
Specification.
|
|
|
|
Overview
|
|
|
|
This extension allows selection of the high- or low-power GPU on
|
|
dual-GPU systems, specifically on macOS.

Additions to the EGL 1.4 Specification
|
|
|
|
Add the following to section 3.7.1 "Creating Rendering Contexts":
|
|
|
|
EGL_POWER_PREFERENCE_ANGLE indicates whether the display should be
|
|
created on the integrated (low-power) or discrete (high-power) GPU
|
|
on dual-GPU systems. EGL_POWER_PREFERENCE_ANGLE is only a legal
|
|
display creation attribute when the EGL_ANGLE_power_preference
|
|
extension is advertised. The valid values for this attribute are
|
|
EGL_LOW_POWER_ANGLE and EGL_HIGH_POWER_ANGLE. If this extension is
|
|
advertised and this display creation attribute is not specified,
|
|
the default value is EGL_LOW_POWER_ANGLE.
