As the dpm clock table is needed during DC HW initialization.
And that (DC HW initialization) comes before smu_late_init()
where current APU dpm clock table setup is performed. So, NULL
pointer dereference will be triggered. By moving APU dpm clock
table setup to smu_hw_init(), this can be avoided.

ttm_mem_type_manager_func.get_node was changed to return -ENOSPC
instead of setting the node pointer to NULL. Unfortunately
vmwgfx still had two places where it was explicitly converting
-ENOSPC to 0 causing regressions. This fixes those spots by
allowing -ENOSPC to be returned. That seems to fix recent
regressions with vmwgfx.

Commit 78fe9f63947a2b ("drm/amd/display: Remove DISPCLK Limit Floor for Certain SMU Versions")
added a call to rn_vbios_smu_get_smu_version() to set clk_mgr->smu_ver.
That field is initialized prior to the if-statement, already.

A recent attempt to fix a ref count leak in
amdgpu_display_crtc_set_config() turned out to be doing too much and
"fixed" an intended decrease as if it were a leak. Undo that part to
restore the proper balance. This is the very nature of this function
to increase or decrease the power reference count depending on the
situation.
Consequences of this bug is that the power reference would
eventually get down to 0 while the display was still in use,
resulting in that display switching off unexpectedly.

DTM topology updates happens by default now. This results in DTM

(NOTE: This is the minimal backportable fix, a full fix is being
developed at https://patchwork.freedesktop.org/patch/388048/)
The flags passed to the wait_entry.func are passed onwards to
try_to_wake_up(), which has a very particular interpretation for its
wake_flags. In particular, beyond the published WF_SYNC, it has a few
internal flags as well. Since we passed the fence->error down the chain
via the flags argument, these ended up in the default_wake_function
confusing the kernel/sched.

To implement preempt-to-busy (and so efficient timeslicing and best utilization
of the hardware submission ports) we let the GPU run asynchronously in respect
to the ELSP submission queue. This created challenges in keeping and accessing
the driver state mirroring the asynchronous GPU execution.
The latest occurence of this was spotted by KCSAN:

To complicate matters, we have to both avoid the read tearing of *active and
avoid any write tearing as perform the pending[] -> inflight[] promotion of the
execlists.
This is because we cannot rely on the memcpy doing u64 aligned copies on all
kernels/platforms and so we opt to open-code it with explicit WRITE_ONCE
annotations to satisfy KCSAN.

As we now protect the timeline list using RCU, we can drop the
timeline->mutex for guarding the list iteration during context close, as
we are searching for an inflight request. Any new request will see the
context is banned and not be submitted. In doing so, pull the checks for
a concurrent submission of the request (notably the
i915_request_completed()) under the engine spinlock, to fully serialise
with __i915_request_submit()). That is in the case of preempt-to-busy
where the request may be completed during the __i915_request_submit(),
we need to be careful that we sample the request status after
serialising so that we don't miss the request the engine is actually
submitting.

Avoid exposing a partially constructed context by deferring the
list_add() from the initial construction to the end of registration.
Otherwise, if we peek into the list of contexts from inside debugfs, we

documentation in include/drm/drm_crtc.h:
* Hence drivers must not consult @active in their various
* &drm_mode_config_funcs.atomic_check callback to reject an atomic
* commit.
atomic_remove_fb disables the CRTC as needed for disabling the primary
plane.
This prevents at least the following problems if the primary plane gets
disabled (e.g. due to destroying the FB assigned to the primary plane,
as happens e.g. with mutter in Wayland mode):
* The legacy cursor ioctl returned EINVAL for a non-0 cursor FB ID
(which enables the cursor plane).
* If the cursor plane was enabled, changing the legacy DPMS property
value from off to on returned EINVAL.
v2:
* Minor changes to code comment and commit log, per review feedback.

[why]
Recent characterization shows increased stutter latencies on some SKUs,
leading to underflow.
[how]
Update SOC params to account for this worst case latency.

[Why]
Previously we were only calling add_topology when hdcp was being enabled.
Now we call add_topology by default so the ERROR messages are printed if
the firmware is not loaded.
This error message is not relevant for normal display functionality so
no need to print a ERROR message.
[How]
Change DRM_ERROR to DRM_INFO

In the resume stage of GPU recovery, start_cpsch will call pm_init

When GPU hang, user process will fail to create a compute queue whose
struct object will be freed later, but driver wrongly add this queue to
queue list of the proccess. And then kfd_process_evict_queues will
access a freed memory, which cause a system crash.
v2:
The failure to execute_queues should probably not be reported to
the caller of create_queue, because the queue was already created.
Therefore change to ignore the return value from execute_queues.

Current BDW virtual display port is initialized as PORT_B, so need
to use same port for VFIO EDID region, otherwise invalid EDID blob
pointer is assigned which caused kernel null pointer reference. We
might evaluate actual display hotplug for BDW to make this function
work as expected, anyway this is always required to be fixed first.
