IMG_context_priority https://www.khronos.org/registry/egl/extensions/IMG/EGL_IMG_context_priority.txt "This extension allows an EGLContext to be created with a priority hint. It is possible that an implementation will not honour the hint, especially if there are constraints on the number of high priority contexts available in the system, or system policy limits access to high priority contexts to appropriate system privilege level. A query is provided to find the real priority level assigned to the context after creation." The extension adds a new eglCreateContext attribute for choosing a priority hint. This stub parses the attribute and copies into the base struct _egl_context, and hooks up the query similarly. Since the attribute is purely a hint, I have no qualms about the lack of implementation before reporting back the value the user gave! v2: Remember to set the default ContextPriority value to medium. v3: Use the driRendererQuery interface to probe the backend for supported priority values and use those to mask the EGL interface. v4: Treat the priority attrib as a hint and gracefully mask any requests not supported by the driver, the EGLContext will remain at medium priority.
