Yes, the change starts from HSW. I'll update the patch.
what's the "rant" I need to insert? I was not in the list a year ago:),
having some trouble find the email as reference.
Any archives I can look into?
No rant to insert for you ;-) That was a placeholder in my mail,
instead of boring people with all the details. Iirc that was to the
internal mailing list, and could be older than a year even.

Essentially there's a bunch of constraints about pixel depth and pfit
usage on recent platforms that we don't quite check correctly. Your
patch update to check for gen >= 8 || IS_HASWELL is perfectly fine
as-is.
