Doesn't look so. AFAIK the architecture of SGX is that there is a single scheduler which is accessed by the register range and it internally has control over multiple cores. > > That is assuming they're really separate instances.. No. There is some internal magic in the driver. It just needs to know that there is one or two nodes. Currently this is handled by some #define option when calling the inner Makefile.
