Thanks,

Thanks Ville,
 
The commit I mentioned below talks about a register at location 2084h. This location is marked as Reserved in the DevSNB PRM docs and only referenced once in reference to bit 2084h[7]. It seems to be some sort of a debug register.
 
I can also see three more subsequent registers at 208ch a.s.o., so I imagine all of this stuff must be documented in this so-called B-Spec (which I am unable to locate on the website).
 
Thanks,
Nick

Bspec is the internal name for the published programmer manuals. It should
be in there, but occasionally something gets lost in the public doc
releases.
