    EGL device extension

Dependencies

34


35
    This extension is written against the language of EGL 1.5 as

36
    modified by EGL_EXT_device_query.

37


38
    EGL_EXT_device_query is required.

Overview

41


42
    ANGLE has the ability to run GPU commands on a native D3D device.

43
    This extension defines a mapping from an EGL device to a D3D

44
    device, after it's queried from an EGL display.

New Tokens

59


60
    Accepted as a queried <attribute> in eglQueryDeviceAttribEXT:

61


62
        EGL_D3D9_DEVICE_ANGLE              0x33A0

63
        EGL_D3D11_DEVICE_ANGLE             0x33A1

64


65
Add a new section 2.1.3 (D3D Devices) after 2.1.2 (Devices)

66


67
    Somewhat analogous to an EGL device, a D3D device establishes a

68
    namespace for D3D operations. In the D3D APIs, such devices are

69
    represented by pointers. For more details, see the D3D

70
    documentation.

71


72
Changes to section 3.2 (Devices)

73


74
    Replace the paragraph immediately following the prototype for

75
    eglQueryDeviceAttribEXT:

76


77
    <attribute> may be either EGL_D3D9_DEVICE_ANGLE or EGL_D3D11_DEVICE_ANGLE.

78
    On success, EGL_TRUE is returned, and a valid D3D9 or D3D11 device pointer

79
    corresponding to the EGL device is returned in <value>. This handle

80
    is compatible with D3D API functions. If the EGL device is not currently

81
    associated with a D3D9 device and <attribute> is EGL_D3D9_DEVICE_ANGLE,

82
    or if the EGL device is not currently associated with a D3D11 device and

83
    <attribute> is EGL_D3D11_DEVICE_ANGLE, EGL_BAD_ATTRIBUTE is returned,

84
    and <value> is left unchanged.
