Hello intel-gfx,
I'm reading i915 gpu drivers and find myself quite hard to understand about
forcewake concepts.
I understand that it is something with the energy efficiency so related to
ACPI. And it looks like forcewake is working as a pair (get and put).
In the "get" part, what it first does i
Add a reference and pointer from the execlist queue item to the associated
gem request. For execlist requests that don't have a request, create one
as a placeholder.

The first pass implementation of execlists required a backpointer to the
context to be held

through the
call stack.

using the reference count added by the "Replace seqno values with
request structures" patchset to ensure that the gem request is available for
the whole execlist submission lifespan.

Where there were duplicate variables for the tail, context and ring (engine)
in the gem request and the execlist queue item, use the one from the request
and remove the duplicate from the execlist queue item.
