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 WebGPU device.
This extension defines a mapping from an EGL device to a WebGPU
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_WEBGPU_DEVICE_ANGLE 0x34F3
EGL_WEBGPU_ADAPTER_ANGLE 0x34F4
Changes to section 3.2 (Devices)
Replace the paragraph immediately following the prototype for
eglQueryDeviceAttribEXT:
<attribute> may be EGL_WEBGPU_DEVICE_ANGLE or EGL_WEBGPU_ADAPTER_ANGLE.
On success, EGL_TRUE is returned, and a valid WGPUDevice or WGPUAdapter
handle corresponding to the EGL device is returned in <value>. wgpuAddRef is
called on the handle before returning and the client is responsible for
releasing this reference. This handle is compatible with WebGPU API functions.
If the EGL device is not currently associated with a WebGPU device and <attribute>
is EGL_WEBGPU_DEVICE_ANGLE or EGL_WEBGPU_ADAPTER_ANGLE, EGL_BAD_ATTRIBUTE is
returned, and <value> is left unchanged.
Issues
None
