Number
EGL Extension #XXX
Extension Type
EGL device extension
Dependencies
This extension is written against the language of EGL 1.5 as
modified by EGL_EXT_device_query.
EGL_EXT_device_query is required.
Overview
ANGLE has the ability to run GPU commands on a native D3D device.
This extension defines a mapping from an EGL device to a D3D
device, after it's queried from an EGL display.
IP Status
No known claims.
New Types
None.
New Procedures and Functions
None.
New Tokens
Accepted as a queried <attribute> in eglQueryDeviceAttribEXT:
EGL_D3D9_DEVICE_ANGLE 0x33A0
EGL_D3D11_DEVICE_ANGLE 0x33A1
Add a new section 2.1.3 (D3D Devices) after 2.1.2 (Devices)
Somewhat analogous to an EGL device, a D3D device establishes a
namespace for D3D operations. In the D3D APIs, such devices are
represented by pointers. For more details, see the D3D
documentation.
Changes to section 3.2 (Devices)
Replace the paragraph immediately following the prototype for
eglQueryDeviceAttribEXT:
<attribute> may be either EGL_D3D9_DEVICE_ANGLE or EGL_D3D11_DEVICE_ANGLE.
On success, EGL_TRUE is returned, and a valid D3D9 or D3D11 device pointer
corresponding to the EGL device is returned in <value>. This handle
is compatible with D3D API functions. If the EGL device is not currently
associated with a D3D9 device and <attribute> is EGL_D3D9_DEVICE_ANGLE,
or if the EGL device is not currently associated with a D3D11 device and
<attribute> is EGL_D3D11_DEVICE_ANGLE, EGL_BAD_ATTRIBUTE is returned,
and <value> is left unchanged.
Issues
