self modifying code and instruction stream obsfucation

greetings.

 

is it in the realm of possibility to push and encrypted instruction stream onto a GCN gpu and have a deobsfucator kernel

decode the stream so as to make it a non trivial task to disassemble a kernel?

what would be needed would be to write to gpu code segments/have self modifying code and be in control of caches that

may have to get flushed i think. any insights?
