If the execbuf is interrupted after building the cmdparser pipeline, and
before we commit to submitting the request to HW, we would attempt to
clean up the cmdparser early. While we held active references to the vma
being parsed and constructed, we did not hold an active reference for
the buffer pool itself. The result was that an interrupted execbuf could
still have run the cmdparser pipeline, but since the buffer pool was
idle, its target vma could have been recycled.
Note this problem only occurs if the cmdparser is running async due to
pipelined waits on busy fences, and the execbuf is interrupted.

The most innocuous result of not having done this is that we end up
sending unnecessary methods when we next enable the window.
However, interactions with the code handling skipping disables when
an update immediately follows, and window ownership assignment, can
lead to upsetting the display hardware on Volta and newer.

Since GM200, SORs are no longer tied to a specific connector, and we
allocate them instead, with the assumption that all SORs are equally
capable.
However, there's a 1<->1 mapping between SOR and HDA pin widget, and
it turns out that it's possible for some widgets to be disabled...
In order to avoid picking a SOR without a valid pin widget, some new
rules need to be added.

[Why]
Whenever we switch between tiled formats without also switching pixel
formats or doing anything else that recreates the DC plane state we
can run into underflow or hangs since we're not updating the
DML parameters before committing to the hardware.
[How]
If the update type is FULL then call validate_bandwidth again to update
the DML parmeters before committing the state.
This is basically just a workaround and protective measure against
update types being added DC where we could run into this issue in
the future.
We can only fully validate the state in advance before applying it to
the hardware if we recreate all the plane and stream states since
we can't modify what's currently in use.
The next step is to update DM to ensure that we're creating the plane
and stream states for whatever could potentially be a full update in
DC to pre-emptively recreate the state for DC global validation.
The workaround can stay until this has been fixed in DM.

While the current locking/serialization of the global state
suffices for protecting the obj->state access and the actual
hardware reprogramming, we do have a problem with accessing
the old/new states during nonblocking commits.
The state computation and swap will be protected by the crtc
locks, but the commit_tails can finish out of order, thus also
causing the atomic states to be cleaned up out of order. This
would mean the commit that started first but finished last has
had its new state freed as the no-longer-needed old state by the
other commit.
To fix this let's just refcount the states. obj->state amounts
to one reference, and the intel_atomic_state holds extra references
to both its new and old global obj states.

With the advent of preempt-to-busy, a request may still be on the GPU as
we unwind. And in the case of a unpreemptible [due to HW] request, that
request will remain indefinitely on the GPU even though we have
returned it back to our submission queue, and cleared the active bit.
We only run the execution callbacks on transferring the request from our
submission queue to the execution queue, but if this is a bonded request
that the HW is waiting for, we will not submit it (as we wait for a
fresh execution) even though it is still being executed.
As we know that there are always preemption points between requests, we
know that only the currently executing request may be still active even
though we have cleared the flag. However, we do not precisely know which
request is in ELSP[0] due to a delay in processing events, and
furthermore we only store the last request in a context in our state
tracker.

When we push a virtual request onto the HW, we update the rq->engine to
point to the physical engine. A request that is then submitted by the
user that waits upon the virtual engine, but along the physical engine
in use, will then see that it is due to be submitted to the same engine
and take a shortcut (and be queued without waiting for the completion
fence). However, the virtual request may be preempted (either by higher
priority users, or by timeslicing) and removed from the physical engine
to be migrated over to one of its siblings. The dependent normal request
however is oblivious to the removal of the virtual request and remains
queued to execute on HW, believing that once it reaches the head of its
queue all of its predecessors will have completed executing!

In order to be valid to dereference during the i915_fence_release, after
retiring the fence and releasing its refererences, we assume that
rq->engine can only be a real engine (that stay intact until the device
is shutdown after all fences have been flushed). However, due to a quirk
of preempt-to-busy, we may retire a request that still belongs to a
virtual engine and so eventually free it with rq->engine being invalid.
To avoid dereferencing that invalid engine, we look at the
execution_mask which if it indicates it may be executed on more than one
engine, we know it originated on a virtual engine and may still be on
one.

reorder passed inter-dependency hogs across the engines. However, we
require preemption to support timeslicing into user payloads, and not all
machine support preemption so we do not universally enable timeslicing,
even when it would correctly preempt our own inter-engine semaphores.
Since timeslicing and semaphore priority deboosting is now disabled on
Broadwell/Braswell, we have to follow suite and not use semaphores.

We recorded the execlists->queue_priority_hint update for the inflight

failed to be scheduled as it had a lower priority than the hint, leaving
the HW running with only the inflight request.

[Why]
Previously we used the s3 codepath for gpu reset. This can lead to issues in
certain case where we end of waiting for fences which will never come (because
parts of the hw are off due to gpu reset) and we end up waiting forever causing
a deadlock.
[How]
Handle GPU reset separately from normal s3 case. We essentially need to redo
everything we do in s3, but avoid any drm calls.
For GPU reset case
suspend:
-Acquire DC lock
-Cache current dc_state
-Commit 0 stream/planes to dc (this puts dc into a state where it can be
powered off)
-Disable interrupts
resume
-Edit cached state to force full update
-Commit cached state from suspend
-Build stream and plane updates from the cached state
-Commit stream/plane updates
-Enable interrupts
-Release DC lock
v2:
-Formatting
-Release dc_state

[Problem description]
1. Boot up picasso platform, launches desktop, Don't do anything (APU enter into "gfxoff" state)
2. Remote login to platform using SSH, then type the command line:
sudo su -c "echo manual > /sys/class/drm/card0/device/power_dpm_force_performance_level"
sudo su -c "echo 2 > /sys/class/drm/card0/device/pp_dpm_sclk" (fix SCLK to 1400MHz)
3. Move the mouse around in Window
4. Phenomenon : The screen frozen
Tester will switch sclk level during glmark2 run time.
APU will enter "gfxoff" state intermittently during glmark2 run time.
The system got hanged if fix GFXCLK to 1400MHz when APU is in "gfxoff"
state.
[Debug]
1. Fix SCLK to X MHz
1400: screen frozen, screen black, then OS will reboot.
1300: screen frozen.
1200: screen frozen, screen black.
1100: screen frozen, screen black, then OS will reboot.
1000: screen frozen, screen black.
900: screen frozen, screen black, then OS will reboot.
800: Situation Nomal, issue disappear.
700: Situation Nomal, issue disappear.
2. SBIOS setting: AMD CBS --> SMU Debug Options -->SMU Debug --> "GFX DLDO Psm Margin Control":
50 : Situation Nomal, issue disappear.
45 : Situation Nomal, issue disappear.
40 : Situation Nomal, issue disappear.
35 : Situation Nomal, issue disappear.
30 : screen black.
25 : screen frozen, then blurred screen.
20 : screen frozen.
15 : screen black.
10 : screen frozen.
5 : screen frozen, then blurred screen.
3. Disable GFXOFF feature
Situation Nomal, issue disappear.
[Why]
Through a period of time debugging with Sys Eng team and SMU team, Sys
Eng team said this is voltage/frequency marginal issue not a F/W or H/W
bug. This experiment proves that default targetPsm [for f=1400MHz] is
not sufficient when GFXOFF is enabled on Picasso.
SMU team think it is an odd test conditions to force sclk="1400MHz" when
GPU is in "gfxoff" state，then wake up the GFX. SCLK should be in the
"lowest frequency" when gfxoff.
[How]
Disable gfxoff when setting manual mode.
Enable gfxoff when setting other mode(exiting manual mode) again.
By the way, from the user point of view, now that user switch to manual
mode and force SCLK Frequency, he don't want SCLK be controlled by
workload.It becomes meaningless to "switch to manual mode" if APU enter "gfxoff"
due to lack of workload at this point.
Tips: Same issue observed on Raven.
