| 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. |
