The only "documentation" we have is in the form of the binary utility docs, which has a list of SASS instructions https://docs.nvidia.com/cuda/cuda-binary-utilities/index.html#ampere-and-ada-instruction-set https://docs.nvidia.com/cuda/cuda-binary-utilities/index.htm... 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)
