This extension name is bad, but I don't have an idea for a better one.

For + example, a Wayland environment may drive multiple GPUs and support both + GLX and EGL clients. In order to realize this, the implementation must + allow the client to specify both device and platform explicitly. + + The EGL_EXT_platform_device extension enables the client to create a + display from a device, but does so by overloading the native_display + argument to eglGetPlatformDisplay; the user passes the device as the + native display, and presumably the EGL picks a sensible default for the + window system. + + EGL_MESA_platform_device differs by passing the device as an attribute + to eglGetPlatformDisplay. This allows the client to name both the device + and the platform. + +New Types + + None + +New Procedures and Functions + + None + +New Tokens + + None + +Additions to the EGL Specification + + None + +New Behavior + + If EGL_DEVICE_EXT is specified as an attribute for eglGetPlatformDisplay, + the value of the attribute is interpreted as an EGLDeviceEXT as returned + by eglQueryDevicesEXT.
