It’s regional, even – people from my part of the US are like to think you sound folksy if you use it. The “all” in “what all” is the same phenomenon as the “all” in “you all” that becomes “y’all”. You can use it with most pronouns – “who all is coming to dinner?” or “where all you been?”. It’s mostly an intensifier.
