--- Comment #1 from Kenneth Graunke <kenneth at whitecape.org> ---
By Gen8.5 do you mean Cherryview/Braswell?

We've not had a good solution for encoding the atom parts in the table.

For example, Ivybridge is Gen 7, Haswell is Gen 7.5, and Baytrail...doesn't
have most of the features from Haswell (so it'd be Gen 7.1/2/3/4?) but also has
features from Broadwell (so, Gen 7.6/7/8/9?).  It just didn't fit at all, so we
left it as "7" and put in special cases for it.

I guess for Cherryview we could consider it Gen 8.<something>.
