For UCLK_FMAX OD feature, SMU overwrites the highest UCLK DPM level freq.
Therefore it can only take values that are greater than the second highest
DPM level freq.

Reference counting in amdgpu_dm_connector for amdgpu_dm_connector::dc_sink
and amdgpu_dm_connector::dc_em_sink as well as in dc_link::local_sink seems
to be out of shape. Thus make reference counting consistent for these
members and just plain increment the reference count when the variable
gets assigned and decrement when the pointer is set to zero or replaced.
Also simplify reference counting in selected function sopes to be sure the
reference is released in any case. In some cases add NULL pointer check
before dereferencing.
At a hand full of places a comment is placed to stat that the reference
increment happened already somewhere else.
This actually fixes the following kernel bug on my system when enabling
display core in amdgpu. There are some more similar bug reports around,
so it probably helps at more places.

This was noticed by Gustavo and his -Wimplicit-fallthrough

rather than falling though, that said, in practice we should
never fall through in the first place so there should be no

drm/imx: handle pending updates better, add plane zpos property support
- Add a mechanism to only send commit done events once all pending
updates have been applied. This closes a small race window where
already armed events could fire even though the double buffered
hardware update just missed the update window.
- Add plane zpos property support to allow placing the overlay plane
behind the primary plane.
- Allow building imx-drm on all platforms under COMPILE_TEST.

Fix for variable refresh rate stuttering

After an event is sent, we try to copy it into the user buffer of the
first waiter in drm_read() and if the user buffer doesn't have enough
room we put it back onto the list. However, we didn't wake up any
subsequent waiter, so that event may sit on the list until either a new
vblank event is sent or a new waiter appears. Rare, but in the worst
case may lead to a stuck process.

In VRR mode, keep track of the vblank count of the last
completed pageflip in amdgpu_crtc->last_flip_vblank, as
recorded in the pageflip completion handler after each
completed flip.
Use that count to prevent mmio programming a new pageflip
within the same vblank in which the last pageflip completed,
iow. to throttle pageflips to at most one flip per video
frame, while at the same time allowing to request a flip
not only before start of vblank, but also anywhere within
vblank.
The old logic did the same, and made sense for regular fixed
refresh rate flipping, but in vrr mode it prevents requesting
a flip anywhere inside the possibly huge vblank, thereby
reducing framerate in vrr mode instead of improving it, by
delaying a slightly delayed flip requests up to a maximum
vblank duration + 1 scanout duration. This would limit VRR
usefulness to only help applications with a very high GPU
demand, which can submit the flip request before start of
vblank, but then have to wait long for fences to complete.
With this method a flip can be both requested and - after
fences have completed - executed, ie. it doesn't matter if
the request (amdgpu_dm_do_flip()) gets delayed until deep
into the extended vblank due to cpu execution delays. This
also allows clients which want to regulate framerate within
the vrr range a much more fine-grained control of flip timing,
a feature that might be useful for video playback, and is
very useful for neuroscience/vision research applications.
In regular non-VRR mode, retain the old flip submission
behavior. This to keep flip scheduling for fullscreen X11/GLX
OpenGL clients intact, if they use the GLX_OML_sync_control
extensions glXSwapBufferMscOML(, ..., target_msc,...) function
with a specific target_msc target vblank count.
glXSwapBuffersMscOML() or DRI3/Present PresentPixmap() will
not flip at the proper target_msc for a non-zero target_msc
if VRR mode is active with this patch. They'd often flip one
frame too early. However, this limitation should not matter
much in VRR mode, as scheduling based on vblank counts is
pretty futile/unusable under variable refresh duration
anyway, so no real extra harm is done.

Exploit that reads of the ring registers return 0 from the engine when

idle then both reads will be identical (and so we interpret the ring as
idle).

When a request has its priority changed, we traverse the graph of all of
its signalers to raise their priorities to match (priority inheritance).
If the request has already started executing its payload, we know that
all of its signalers must have signaled and we do not need to process
our list of signalers.

Read the HDMI infoframes from the hbuf and unpack them into
the crtc state.
Well, actually just AVI infoframe for now but let's write the
infoframe readout code in a more generic fashion in case we
expand this later.
Note that Daniel was sceptical about the benefit if this and
also concerned about the potential for crappy sdvo encoders not
implementing the hbuf read commands. My (admittedly limited)
experience is that such encoders don't implement even the
get/set hdmi encoding commands and thus would always be treated
as dvi only. Hence I believe this is safe, and also IMO preferable
having quirks to deal with missing readout support. The readout
support is neatly isolated in the sdvo code whereas the quirk
would leak to other parts of the driver (state checker, fastboot,
etc.) thus complicating the lives of other people.

In selftests/live_hangcheck, we have a lot of tests for resetting simple
spinners, but nothing quite prepared us for how the GPU reacted to
triggering a reset outside of the safe spinner. These two subtests fill
the ring with plain old empty, non-spinning requests, and then triggers
a reset. Without a user-payload to blame, these requests will exercise
the 'non-started' paths and mostly be replayed verbatim.

To determine whether an engine has 'stuck', we simply check whether or
not is still on the same seqno for several seconds. To keep this simple
mechanism intact over the loss of a global seqno, we can simply add a
new global heartbeat seqno instead. As we cannot know the sequence in
which requests will then be completed, we use a primitive random number
generator instead (with a cycle long enough to not matter over an
interval of a few thousand requests between hangcheck samples).
The alternative to using a dedicated seqno on every request is to issue
a heartbeat request and query its progress through the system. Sadly
this requires us to reduce struct_mutex so that we can issue requests
without requiring that bkl.
v2: And without the extra CS_STALL for the hangcheck seqno -- we don't
need strict serialisation with what comes later, we just need to be sure
we don't write the hangcheck seqno before our batch is flushed.

Currently there is a small race window where we could manage to arm the
vblank event from atomic flush, but programming the hardware was too close
to the frame end, so the hardware will only apply the current state on the
next vblank. In this case we will send out the commit done event too early
causing userspace to reuse framebuffes that are still in use.
Instead of using the event arming mechnism, just remember the pending event
and send it from the vblank IRQ handler, once we are sure that all state
has been applied successfully.

zpos without modeset.
Note that the initial zpos is set in ipu_plane_state_reset(). The
