/*
 * The following structures are used to define test cases.
 *
 * Each test case consists of a test case setup and a test case expectaction.
 * and a expected result, consisting
 * of an array of monitors, logical monitors and a screen size.
 *
 * TEST CASE SETUP:
 *
 * A test case setup consists of an array of modes, an array of outputs and an
 * array of CRTCs.
 *
 * A mode has a width and height in pixels, and a refresh rate in updates per
 * second.
 *
 * An output has an array of available modes, and a preferred mode. Modes are
 * defined as indices into the modes array of the test case setup.
 *
 * It also has CRTc and an array of possible CRTCs. Crtcs are defined as indices
 * into the CRTC array. The CRTC value -1 means no CRTC.
 *
 * It also has various meta data, such as physical dimension, tile info and
 * scale.
 *
 * A CRTC only has a current mode. A mode is defined as an index into the modes
 * array.
 *
 *
 * TEST CASE EXPECTS:
 *
 * A test case expects consists of an array of monitors, an array of logical
 * monitors, a output and crtc count, and a screen width.
 *
 * A monitor represents a physical monitor (such as an external monitor, or a
 * laptop panel etc). A monitor consists of an array of outputs, defined by
 * indices into the setup output array, an array of monitor modes, and the
 * current mode, defined by an index into the monitor modes array, and the
 * physical dimensions.
 *
 * A logical monitor represents a region of the total screen area. It contains
 * the expected layout and a scale.

 * after the kernel emits a DRM hotplug — most often caused by the
 * monitor itself performing an auto input-scan and re-toggling its

 *
 * Without the fix, ensure_configured() walked past current_config and
