Nope - storage keys are only accessible using special instructions. They're not in RAM (visible to a guest) :).


Interesting, so where are they kept? An on-chip memory? That would limit the amount of main memory to that indexed by the chip. Extra off-chip memory?

Asking purely out of interest, this has no bearing on the patch.
