The struct rcar_du_encoder_data encoder::field describes the encoder

fixup for drm/i915: Add vma to list at creation
|
|
formerly: "drm/i915: Create VMAs (part 4) - Error capture"
Since the active/inactive lists are per VM, we need to modify the error
capture code to be aware of this, and also extend it to capture the
buffers from all the VMs. For now all the code assumes only 1 VM, but it
will become more generic over the next few patches.
NOTE: If the number of VMs in a real world system grows significantly
we'll have to focus on only capturing the guilty VM, or else it's likely
there won't be enough space for error capture.
v2: Squashed in the "part 6" which had dependencies on the mm_list
change. Since I've moved the mm_list change to an earlier point in the
series, we were able to accomplish it here and now.

formerly: "drm/i915: Create VMAs (part 5) - move mm_list"
The mm_list is used for the active/inactive LRUs. Since those LRUs are
per address space, the link should be per VMx .
Because we'll only ever have 1 VMA before this point, it's not incorrect
to defer this change until this point in the patch series, and doing it
here makes the change much easier to understand.
Shamelessly manipulated out of Daniel:
"active/inactive stuff is used by eviction when we run out of address
space, so needs to be per-vma and per-address space. Bound/unbound otoh
is used by the shrinker which only cares about the amount of memory used
and not one bit about in which address space this memory is all used in.
Of course to actual kick out an object we need to unbind it from every
address space, but for that we have the per-object list of vmas."

formerly: "drm/i915: Create VMAs (part 3.5) - map and fenceable
tracking"
The map_and_fenceable tracking is per object. GTT mapping, and fences
only apply to global GTT. As such, object operations which are not
performed on the global GTT should not effect mappable or fenceable
characteristics.
Functionally, this commit could very well be squashed in to a previous
patch which updated object operations to take a VM argument. This
commit is split out because it's a bit tricky (or at least it was for
me).

In some places, we want to know if an object is bound in any address
space, and not just the global GTT. This often applies when there is a
single global resource (object, pages, etc.)
function | reason
--------------------------------------------------
i915_gem_object_is_inactive | global object
i915_gem_object_put_pages | object's pages
915_gem_object_unpin | global object
i915_gem_execbuffer_unreserve_object | temporary until we plumb vma
pread/pwrite | see the note below
Note: set_to_gtt_domain in pwrite/pread is abused as a wait_rendering
call - but that once only worked if the object is bound. We really
should replace this with a plain wait_rendering call, which would have
the upside that in pread it would be clearer that we actually only
wait for oustanding gpu writes.
