Version 1, January 22, 2024
Number
EGL Extension XXX
Extension Type
EGL client extension
Dependencies
Requires ANGLE_platform_angle.
Overview
This extension enables selection of WebGPU display types.
New Types
None
New Procedures and Functions
None
New Tokens
Accepted as values for the EGL_PLATFORM_ANGLE_TYPE_ANGLE attribute:
EGL_PLATFORM_ANGLE_TYPE_WEBGPU_ANGLE 0x34DF
Accepted as an attribute name in the <attrib_list> argument of
eglGetPlatformDisplayEXT:
EGL_PLATFORM_ANGLE_DAWN_PROC_TABLE_ANGLE 0x3480
EGL_PLATFORM_ANGLE_WEBGPU_DEVICE_ANGLE 0x34F6
Additions to the EGL Specification
None.
New Behavior
To request a display that translates to WebGPU, the value of
EGL_PLATFORM_ANGLE_TYPE_ANGLE should be
EGL_PLATFORM_ANGLE_TYPE_WEBGPU_ANGLE.
To configure the WebGPU function pointers used, use the attribute
EGL_PLATFORM_ANGLE_DAWN_PROC_TABLE_ANGLE. The value of
EGL_PLATFORM_ANGLE_DAWN_PROC_TABLE_ANGLE should be a pointer to
a DawnProcTable. If a proc table is not provided or the provided
proc table is NULL, an implementation specific one will be used.
To use an existing WebGPU adapter and device, use the attribute
EGL_PLATFORM_ANGLE_WEBGPU_DEVICE_ANGLE.
EGL_PLATFORM_ANGLE_WEBGPU_DEVICE_ANGLE should be a WGPUDevice handle.
If a device is not provided or is NULL, an implementation specific
one will be used.
Issues
None
