Everything in the list you provided, looks to be related to the Test Pattern Generator (TPG).  You can find more information in PG103 Video Test Pattern Generator or on the TPG V4L2 Wiki Page.

Also of note:  At this point 2017.1 is quite old and the Video Drivers have had significant updates.  I recommend moving to the latest version (2019.1 or 2019.1) to get all the fixes and improvements.
