The OoO TLB ignored A/D on hit and PTW, so a missing A (or a store with missing D) translated successfully. Mirror EmbeddedTLB: raise a page fault unless FPGAPlatform, which keeps the hardware A/D update path.
Default off, so missing A or (store and missing D) raises a page fault on both TLB paths. Set EnableUpdateAD to restore PTE write-back. Independent of FPGAPlatform.
