EGL Extension XXX
Extension Type
EGL client extension
Dependencies
Requires ANGLE_platform_angle.
Overview
This extension allows the client to request a Display that internally
virtualizes contexts. Requesting virtualized contexts may impact
performance or ability to render from multiple threads simultaneously.
New Types
None
New Procedures and Functions
None
New Tokens
Accepted as an attribute name in the <attrib_list> argument of
eglGetPlatformDisplayEXT:
EGL_PLATFORM_ANGLE_CONTEXT_VIRTUALIZATION_ANGLE 0x3481
Additions to the EGL Specification
None.
New Behavior
To request a display that internally utilizes context virtualization,
use the attribute EGL_PLATFORM_ANGLE_CONTEXT_VIRTUALIZATION_ANGLE.
EGL_TRUE enables context virtualization and EGL false disables it.
If it is set to EGL_DONT_CARE, the default setting depends on the
implementation. Any value other than these will result in an error.
The default value for EGL_PLATFORM_ANGLE_CONTEXT_VIRTUALIZATION_ANGLE
is EGL_DONT_CARE. Display creation may fail if hardware limitations
prohibit the requested setting.
Issues
None
