drm/i915: Make sure engines are idle during GPU idling in LR mode
We assume that the GPU is idle once receiving the seqno via the last
request's user interrupt. In execlist mode the corresponding context
completed interrupt can be delayed though and until this latter
interrupt arrives we consider the request to be pending on the ELSP
submit port. This can cause a problem during system suspend where this
last request will be seen by the resume code as still pending. Such
pending requests are normally replayed after a GPU reset, but during
resume we reset both SW and HW tracking of the ring head/tail pointers,
so replaying the pending request with its stale tail pointer will leave
the ring in an inconsistent state. A subsequent request submission can
lead then to the GPU executing from uninitialized area in the ring
behind the above stale tail pointer.
Fix this by making sure any pending request on the ELSP port is
completed before suspending. I used a polling wait since the completion
time I measured was <1ms and since normally we only need to wait during
system suspend. GPU idling during runtime suspend is scheduled with a
delay (currently 50-100ms) after the retirement of the last request at
which point the context completed interrupt must have arrived already.

There are only 4 firmware files we may want to look up that way, so

drm/nouveau/kms/nv50: transition to atomic interfaces internally
This commit implements the atomic commit interfaces, and implements the
legacy modeset and page flipping interfaces on top of them.
There's two major changes in behavior from before:
- We're now making use of interlocks between core and satellite EVO
channels, which greatly improves our ability to keep their states
synchronised.
- DPMS is now implemented as a full modeset to either tear down the
entire pipe (or bring it back up). This choice was made mostly
to ease the initial implementation, but I'm also not sure what we
gain by bring backing the old behaviour. We shall see.
This does NOT currently expose the atomic ioctl by default, due to
limited testing having been performed.

Under atomic modesetting, we will instead be doing a full modeset to

drm/nouveau/kms/nv50: separate out core surface commit
This commit separates the calculation of EVO state from the commit, in
order to make the same code useful for atomic modesetting.
The legacy interfaces have been wrapped on top of them.
As of this commit, we're no longer bothering to point the core surface
at a valid framebuffer. Prior to this, we'd initially point the core
channel to the framebuffer passed in a mode_set()/mode_set_base(), and
then use the base channel for any page-flip updates, leaving the core
channel pointing at stale information.
The important thing here is to configure the core surface parameters in
such a way that EVO's error checking is satisfied.
TL;DR: The situation isn't too much different to before.
There may be brief periods of times during modesets where the (garbage)
core surface will be showing. This issue will be resolved once support
for atomic commits has been implemented and we're able to interlock the
updates that involve multiple channels.

drm/nouveau: hide gcc-4.9 -Wmaybe-uninitialized
gcc-4.9 notices that the validate_init() function returns unintialized
data when called with a zero 'nr_buffers' argument, when called with the
-Wmaybe-uninitialized flag:
drivers/gpu/drm/nouveau/nouveau_gem.c: In function ‘validate_init.isra.6’:
drivers/gpu/drm/nouveau/nouveau_gem.c:457:5: error: ‘ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
However, the only caller of this function always passes a nonzero
argument, and gcc-6 is clever enough to take this into account and
not warn about it any more.
Adding an explicit initialization to -EINVAL here is correct even if
the caller changed, and it avoids the warning on gcc-4.9 as well.

In fact, both functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.

This fixes (works around?) link training failures seen on (at least)
the Lenovo P50's internal panel.
It's also an important fix on the same system for MST support on the
dock. Sometimes, right after receiving an IRQ from the sink, there's
an error bit (SINKSTAT_ERR) set in the DPAUX registers before we've
even attempted a transaction.
