Celeron J1900 supports EPT

Quick post. I was shopping for a new home server and was eyeing the new Intel Bay Trail CPUs. The only thing that deterred me from buying it was Intel ARK insisting that Celeron J1900 doesn’t support the Extended Page Table (aka Nested Page Table) feature.

From the past I know that ARK is not exactly the best source of knowledge on EPT (go figure) so I kept searching, but I couldn’t find a confirmation. I found a mention of EPT in someone’s /proc/cpuinfo dump, so I bit the bullet and bought it.
