Jarkko,
You can test the non-execution paths (e.g. where the memory error is
reported by a patrol scrubber in the memory controller) by:
# echo 0x{some_SGX_EPC_ADDRESS} > /sys/devices/system/memory/hard_offline_page
The execution paths are more difficult. You need a system that can inject
errors into EPC memory. There are some hints in the Documenation changes
in part 0006.
Reinette posted some changes to sgx tests that she used to validate.
