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 context 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
|
||
|
|
context 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 context creation attribute is not specified,
|
||
|
|
the default value is EGL_LOW_POWER_ANGLE.
|
||
|
|
|
||
|
|
The containing application must set the
|
||
|
|
NSSupportsAutomaticGraphicsSwitching attribute to true in its
|
||
|
|
Info.plist in order for this extension to operate as advertised.
