No, neither guest support nor host exploitation is included in current
versions of z/VM.

z/VM does not currently support the Enhanced DAT Facility. And it's not
quite as simple as "improves performance". There are tradeoffs involved,
and it's not exactly a small undertaking.

Hi,
I have a zTPF guy who tells me that z/TPF will support the enhanced DAT
facility soon to improve performance.
When I checked our CPU facility list installed, the machine native shows
the enhanced DAT facility installed, but z/VM does not.
I am wondering if this facility is z/VM generation
