Since I know you know all of this, I prefixed my remarks with "Well yes, sorta." I just made two (slight) distinctions. 1. that work done by a TCB is charged to the TCB and its home address space (or enclave) EVEN WHEN it runs in cross memory mode in another address space. I count cross memory time as "time spent in another address space." 2. EVEN IF the requesting TCB is joined to an enclave, resources consumed on its behalf by another server TCB (such as those in CAS) WILL NOT be charged to the requestor's TCB and enclave UNLESS the server goes to the trouble of joining its worker task to the enclave prior to commencing work on the requestors behalf and leaving the enclave afterward. CAS definitely doesn't do that. Some other server programs do.
