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 metal device.
|
|
This extension defines a mapping from an EGL device to a metal
|
|
device, after it's queried from an EGL display.

|
|
|
|
New Tokens
|
|
|
|
Accepted as a queried <attribute> in eglQueryDeviceAttribEXT:
|
|
|
|
EGL_METAL_DEVICE_ANGLE 0x34A6
|
|
|
|
Add a new section 2.1.3 (Metal Devices) after 2.1.2 (Devices)
|
|
|
|
Somewhat analogous to an EGL device, a Metal device establishes a
|
|
namespace for Metal operations. In the Metal APIs, such devices are
|
|
represented by pointers. For more details, see the Metal
|
|
documentation.
|
|
|
|
Changes to section 3.2 (Devices)
|
|
|
|
Replace the paragraph immediately following the prototype for
|
|
eglQueryDeviceAttribEXT:
|
|
|
|
<attribute> may be EGL_METAL_DEVICE_ANGLE.
|
|
On success, EGL_TRUE is returned, and a valid MTLDevice pointer
|
|
corresponding to the EGL device is returned in <value>. This handle
|
|
is compatible with Metal API functions. If the EGL device is not currently
|
|
associated with a Metal device and <attribute> is EGL_METAL_DEVICE_ANGLE,
|
|
EGL_BAD_ATTRIBUTE is returned, and <value> is left unchanged.
