/**
* intel_lr_context_size() - return the size of the context for an engine
* @ring: which engine to find the context size for
*
* Each engine may require a different amount of space for a context image,
* so when allocating (or copying) an image, this function can be used to
* find the right size for the specific engine.
*
* Return: size (in bytes) of an engine-specific context image
*
* Note: this size includes the HWSP, which is part of the context image
* in LRC mode, but does not include the "shared data page" used with
* GuC submission. The caller should account for this if using the GuC.
