To test if only the modified regions are updated after a sync, we will need to create situations where the two are mismatched. Split this check into another function that we can skip calling, since we won't want it to error on those mismatched cases.

There is another check that the copy frame buffer is the same as that. But neither is enough to test if only the modified regions are copied to the copy frame buffer, since we will want the two to be different in very specific ways. Add a boolean argument to the existing helper function to indicate which frame buffer we want to inspect, and update the existing callers.

This includes pretty much the full line contents of the printed character. Since we now have proper damage tracking, let's make use of that to reduce the amount of data we need to copy. With this patch applied, we will only copy the tiny rectangle surrounding characters when we print them, speeding up the video console. After this, changes to the main frame buffer are not immediately copied to the copy frame buffer, but postponed until the next video device sync. So issue an explicit sync before inspecting the copy frame buffer contents for the video tests.

However, dcaches exist on other platforms as well and may need clearing if their driver requires it. Simplify the compile logic and always enable the dcache flush logic in the video core. That way, drivers can always rely on it to call the arch specific callbacks. This will increase code size for non-ARM platforms with CONFIG_VIDEO=y slightly.

These drivers benefit from our new video damage control, because we can reduce the amount of memory that gets flushed significantly. This patch enables video damage control for all device drivers that call video_set_flush_dcache() to make sure they benefit from it.
