Description

This extension is intended to convey throttle hints to the device, but does not specify the throttling behavior or any minimum guarantees. This extension is intended to communicate information from layered API implementations such as ANGLE to internal proprietary system schedulers.

It has no behavioral implications beyond enabling more intelligent behavior from the system scheduler.

Application developers should avoid using this extension. It is documented solely for the benefit of tools and layer developers, who may need to manipulate pNext chains that include these structures.

Note

There is currently no specification language written for this extension. The links to APIs defined by the extension are to stubs that only include generated content such as API declarations and implicit valid usage statements.
Note

This extension is only intended for use in specific embedded environments with known implementation details, and is therefore undocumented.
