From: Ilya Bakoulin <[email protected]> [Why] Iterating over every voltage state when we need to validate thousands of configurations all at once (i.e. display hotplug) can take a significant amount of time.
[How] Check just the highest voltage state when fast_validate is true to verify whether the configuration can work at all, then do a proper validation including all voltage states later when fast_validate is false.
