I am working with i5-6600 (6th generation).
I've tried to read TAD (Target Address Decoder) using PCI bus. And the value was all 1s.
I've heard that
1) SAD/TAD is disabled when SGX is disabled.
2) When accessing PRM with non-enclave mode processor, read request is aborted and the result turns out to be all 1s.
With facts of 1, 2,
I am guessing that 'TAD is in PRM & I cannot access it when SGX is disabled'.
Am I guessing right?
i.e., I want to access TAD w/o enabling SGX. Is it possible?
If possible, is there any document or other kind of hint for it?
