| Overview |
| |
| This extension allows the client to create contexts that are internally |
| virtualized on a single native context for performance or stability. |

| New Tokens |
| |
| Accepted as an attribute name in the <attrib_list> argument of |
| eglCreateContext: |
| |
| EGL_CONTEXT_VIRTUALIZATION_GROUP_ANGLE 0x3481 |
| |
| Additions to the EGL Specification |
| |
| None. |
| |
| New Behavior |
| |
| To request that a context should be part of a virtualization group, |
| use the attribute EGL_CONTEXT_VIRTUALIZATION_GROUP_ANGLE. EGL_DONT_CARE |
| can be used to allow the implementation to decide what virtualization |
| group is used. The default value of EGL_CONTEXT_VIRTUALIZATION_GROUP_ANGLE |
| is EGL_DONT_CARE. It is undefined behaviour to have multiple contexts from |
| the same virtualization group current different threads simultaneously. |
