drm/scheduler: fix timeout worker setup for out of order job completions
drm_sched_job_finish() is a work item scheduled for each finished job on
a unbound system workqueue. This means the workers can execute out of order
with regard to the real hardware job completions.
If this happens queueing a timeout worker for the first job on the ring
mirror list is wrong, as this may be a job which has already finished
executing. Fix this by reorganizing the code to always queue the worker
for the next job on the list, if this job hasn't finished yet. This is
robust against a potential reordering of the finish workers.
Also move out the timeout worker cancelling, so that we don't need to
take the job list lock twice. As a small optimization list_del is used
to remove the job from the ring mirror list, as there is no need to
reinit the list head in the job we are about to free.

drm/amd/display: Use calculated disp_clk_khz value for dce110
[Why]
The calculated values for actual disp_clk_khz were ignored when
notifying pplib of the new display requirements. In order to honor DFS
bypass clocks from the hardware, the calculated value should be used.
[How]
The return value for set_dispclk is now assigned back into new_clocks
and correctly carried through into dccg->clks.phyclk_khz. When notifying
pplib of new display requirements dccg->clks.phyclk_khz is used
instead of dce.dispclk_khz. The value of dce.dispclk_khz was never
explicitly set to anything before.
A 15% higher display clock value than calculated is no longer requested
for dce110 since it now makes use of the calculated value.
Since dce112 makes use of dce110's set_bandwidth but not its
update_clocks it needs to have the value correctly carried through.

drm/i915: Interactive RPS mode
RPS provides a feedback loop where we use the load during the previous
evaluation interval to decide whether to up or down clock the GPU
frequency. Our responsiveness is split into 3 regimes, a high and low
plateau with the intent to keep the gpu clocked high to cover occasional
stalls under high load, and low despite occasional glitches under steady
low load, and inbetween. However, we run into situations like kodi where
we want to stay at low power (video decoding is done efficiently
inside the fixed function HW and doesn't need high clocks even for high
bitrate streams), but just occasionally the pipeline is more complex
than a video decode and we need a smidgen of extra GPU power to present
on time. In the high power regime, we sample at sub frame intervals with
a bias to upclocking, and conversely at low power we sample over a few
frames worth to provide what we consider to be the right levels of
responsiveness respectively. At low power, we more or less expect to be
kicked out to high power at the start of a busy sequence by waitboosting.
Prior to commit
e9af4ea2b9e7 ("drm/i915: Avoid waitboosting on the active
request") whenever we missed the frame or stalled, we would immediate go
full throttle and upclock the GPU to max. But in commit
e9af4ea2b9e7, we
relaxed the waitboosting to only apply if the pipeline was deep to avoid
over-committing resources for a near miss. Sadly though, a near miss is
still a miss, and perceptible as jitter in the frame delivery.
To try and prevent the near miss before having to resort to boosting
after the fact, we use the pageflip queue as an indication that we are
in an "interactive" regime and so should sample the load more frequently
to provide power before the frame misses it vblank. This will make us
more favorable to providing a small power increase (one or two bins) as
required rather than going all the way to maximum and then having to
work back down again. (We still keep the waitboosting mechanism around
just in case a dramatic change in system load requires urgent uplocking,
faster than we can provide in a few evaluation intervals.)
v2: Reduce rps_set_interactive to a boolean parameter to avoid the
confusion of what if they wanted a new power mode after pinning to a
different mode (which to choose?)
v3: Only reprogram RPS while the GT is awake, it will be set when we
wake the GT, and while off warns about being used outside of rpm.
v4: Fix deferred application of interactive mode

happy to see this upstream so further feature work can procede on top
of upstream.
Also includes the gpu coredump support, which should be useful for
debugging gpu crashes. And various other misc fixes and such.

drm/amdgpu/pm: Fix potential Spectre v1
idx can be indirectly controlled by user-space, hence leading to a
potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c:408 amdgpu_set_pp_force_state()
warn: potential spectre issue 'data.states'
Fix this by sanitizing idx before using it to index data.states
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

drm/radeon: Replace ttm_bo_unref with ttm_bo_put
The function ttm_bo_put releases a reference to a TTM buffer object. The
function's name is more aligned to the Linux kernel convention of naming
ref-counting function _get and _put.
A call to ttm_bo_unref takes the address of the TTM BO object's pointer and
clears the pointer's value to NULL. This is not necessary in most cases and
sometimes even worked around by the calling code. A call to ttm_bo_put only
releases the reference without clearing the pointer.
The current behaviour of cleaning the pointer is kept in the calling code,
but should be removed if not required in a later patch.
