Number

    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
