One thing I greatly dislike about the settings app is the fact we can only have one section opened at once. If you are debugging, say Bluetooth and sound issues, the setting app can only exclusively show either Bluetooth or Sound, not both, (AFAIK) you can't open a second instance of the app.
though there is no guarantee this is exhaustive, no opcodes either (though you could reverse engineer it using cuobjdump -sass and a hex editing like I've been doing). I'm pretty sure some of the instructions in the list are deprecated as well (95% percent sure that PMTRIG does nothing >Volta)
I watched the Ken Burns' Vietnam documentary a few weeks ago, this reminds me of the claims that the Nixon campaign pretty much did the same thing in '68 with the Republic of Vietnam and the peace talks (i.e. our guy will get you a better deal.)
