Check plane->fb in intel_disable_plane() to determine if the plane
is already disabled.
If the plane has an fb, then it must also have a crtc, so we can drop
the plane->crtc check and just call intel_enable_primary() directly.

Give a name to the plane watermark related data we have currently
stored under intel_plane->wm.
We also observe that this data is more or less the same that we have
in the hsw_pipe_wm_parameters structure, so use it there as well.

There is a bunch of global state that needs to be considered when
checking watermarks for validity. Move most of that to a new
structure intel_wm_config, to avoid having to pass around so
many variables.
One notable thing left out is the DDB partitioning information,
since we often anyway need to check the same watermarks against
both 1/2 and 5/6 DDB partitioning layouts.

Refactor the code a bit to split the watermark level validity check into
a separate function.
Also add hack there that allows us to use it even for LP0 watermarks.
ATM we don't pre-compute/check the LP0 watermarks, so we just have to
clamp them to the maximum and hope things work out.

With the current code there shouldn't be a distinction - however with an
upcoming change we intend to allocate a vma much earlier, before it's
actually bound anywhere.
To do this we have to check node allocation as well for the _bound()
check.

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).

If the user if this API is providing a bigger buffer than the infoframe
size, it could be for a could reason. For instance it could be because
it gives the buffer that will be written to the hardware, up to the
maximum of an infoframe size.
Instead of just zeroing up to the infoframe size, let's zero the whole
incoming buffer as those extra bytes are also used to compute the
ECC and need to be 0.

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.

As alluded to in several patches, and it will be reiterated later... A
VMA is an abstraction for a GEM BO bound into an address space.
Therefore it stands to reason, that the existing bind, and unbind are
the ones which will be the most impacted. This patch implements this,
and updates all callers which weren't already updated in the series
(because it was too messy).
This patch represents the bulk of an earlier, larger patch. I've pulled
out a bunch of things by the request of Daniel. The history is preserved
for posterity with the email convention of ">" One big change from the
original patch aside from a bunch of cropping is I've created an
i915_vma_unbind() function. That is because we always have the VMA
anyway, and doing an extra lookup is useful. There is a caveat, we
retain an i915_gem_object_ggtt_unbind, for the global cases which might
not talk in VMAs.

The driver used to assume that the streaming endpoint's wMaxPacketSize
value would be an indication of how much data the endpoint expects or
sends, and compute the number of packets per URB using this value.
However, the Focusrite Scarlett 2i4 declares a value of 1024 bytes,
while only about 88 or 44 bytes are be actually used. This discrepancy
would result in URBs with far too few packets, which would not work
correctly on the EHCI driver.
To get correct URBs, use wMaxPacketSize only as an upper limit on the
packet size.

When using 64kB pages, we only have two levels of page tables,
meaning that PGD, PUD and PMD are fused. In this case, trying
to refcount PUDs and PMDs independently is a a complete disaster,
as they are the same.
We manage to get it right for the allocation (stage2_set_pte uses
{pmd,pud}_none), but the unmapping path clears both pud and pmd
refcounts, which fails spectacularly with 2-level page tables.
The fix is to avoid calling clear_pud_entry when both the pmd and
pud pages are empty. For this, and instead of introducing another
pud_empty function, consolidate both pte_empty and pmd_empty into
page_empty (the code is actually identical) and use that to also
test the validity of the pud.

the rlc ucode is missing, don't enable dpm. Enabling
