| |
| EGL client extension |
| |
| Dependencies |
| |
| Requires ANGLE_platform_angle. |
| |
| Overview |
| |
| This extension allows the client to request a Display that internally |
| virtualizes contexts. Requesting virtualized contexts may impact |
| performance or ability to render from multiple threads simultaneously. |

| Accepted as an attribute name in the <attrib_list> argument of |
| eglGetPlatformDisplayEXT: |
| |
| EGL_PLATFORM_ANGLE_CONTEXT_VIRTUALIZATION_ANGLE 0x3481 |
| |
| Additions to the EGL Specification |
| |
| None. |
| |
| New Behavior |
| |
| To request a display that internally utilizes context virtualization, |
| use the attribute EGL_PLATFORM_ANGLE_CONTEXT_VIRTUALIZATION_ANGLE. |
| EGL_TRUE enables context virtualization and EGL false disables it. |
| If it is set to EGL_DONT_CARE, the default setting depends on the |
| implementation. Any value other than these will result in an error. |
| The default value for EGL_PLATFORM_ANGLE_CONTEXT_VIRTUALIZATION_ANGLE |
| is EGL_DONT_CARE. Display creation may fail if hardware limitations |
| prohibit the requested setting. |
