| 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. |
| |
| IP Status |
| |
| No known claims. |
| |
| New Types |
| |
| None. |
| |
| New Procedures and Functions |
| |
| None. |
| |
| 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. |
