TGL introduced a feature in which we map the main surface to the
auxilliary surface. If we screw up the page tables, the HW has a
register to tell us which engine encounters a fault in the page table
walk.
Platform specific, or for likely all gen12 and then gen12+?
It also applies to the new DGFX patches that started trickling down.
Though I don't know where the Gen12 boundary is which is why I went with
platform name.
In Mesa we went for a flag on the device_info struct so it's easy to
toggle on/off for a particular product.

I'm reminded of my desire to just grab a snapshot of all nearby mmio and
zip it up.
Yep... And jsonify it or something? ;)
