Number

    EGL Extension #XXX

Extension Type

    EGL client extension

Dependencies

    Requires EGL_ANGLE_device_d3d and EGL_ANGLE_device_creation.

    Written against the wording of EGL 1.5 as modified by EGL_ANGLE_device_d3d
    and EGL_ANGLE_device_creation.

Overview

    ANGLE has the ability to run GPU commands on a native D3D device. This
    extension defines a way to create a EGL device which maps to an inputted
    Direct3D 11 device.

    This extension is intended to be used with EGL_EXT_platform_device to
    initialize a display using an existing Direct3D 11 device, but
    EGL_EXT_platform_device is not required.

IP Status

    No known claims.

Changes to section 3.2 (Devices)

    Modify the language in section 3.2 (Devices) describing valid attribute
    names passed into eglCreateDeviceANGLE via <device_type>:

    "This specification defines one value for <device_type>:
    EGL_D3D11_DEVICE_ANGLE. If this device type is specified then
    <native_device> must be a valid pointer to a Direct3D 11 device. If
    <native_device> is not a valid pointer to a Direct3D 11 device then the
    resulting behavior is undefined."

    Append the following to the end of section 3.2 (Devices):

    "If a Direct3D 11 device used to create a device experiences a "lost device"
    then all resulting behavior of the device (and any dependent EGL objects) is
    undefined. It is the caller's responsibility to monitor for "lost device"
    and to create a new device (and dependent EGL objects) as appropriate. For
    more information on "lost device", see the Direct3D documentation."

Issues

    None.
