Currently, we scan the list of mappings each time we want to operate on
the vram_mapping struct. Rather than repeatedly scanning these, look
them up once in the submission path, and then use _reference and
_unreference methods as necessary to manage this object.

Improve the readibility of the function which inserts command buffers
and other maintanence commands into the GPUs ring buffer. We do this
by splitting the ring buffer reservation in two: one chunk for any
commands that need to be issued prior to the command buffer, and a
separate chunk for commands issued after the buffer.
The result is a much more obvious code flow in this function, and
localisation of the conditional maintanence commands prior to the
command buffer.

If the end of the system DMA window is farther away from the start of
physical RAM than the size of the GPU linear window, move the linear
window so that it ends at the same address than the system DMA window.
This allows to map command buffer from CMA, which is likely to reside
at the end of the system DMA window, while also overlapping as much
RAM as possible, in order to optimize regular buffer mappings through
the linear window.

The retire worker is kicked for each fence, either the normal way
by signaling the fence from the event completion interrupt or by
the recover worker if the GPU got stuck. Moving the RPM put into
the retire worker allows us to have it in a single place for
both cases.
This also shaves off quite a bit of the CPU time spent in hardirq
context, as arming the autosuspend timer when the RPM refcount
drops to 0 is a relatively costly operation.

In commit 1e657ad7 we moved the last step of firmware initialization to
skl_display_core_init(), where it will be run only during system resume,
but not during driver loading. Since this init step needs to be done
whenever we program the firmware fix this by moving the initialization
to the end of intel_csr_load_program().
While at it simplify a bit csr_load_work_fn().
This issue prevented DC5/6 transitions, this change will re-enable those.
v2:
- remove debugging left-over and redundant comment in csr_load_work_fn()

This is a port of the patch "drm/amdgpu: Fix error handling in amdgpu_flip_work_func."
to fix the following problem for radeon as well which was
reported against amdgpu:
The patch e1d09dc0ccc6: "drm/amdgpu: Don't hang in
amdgpu_flip_work_func on disabled crtc." from Feb 19, 2016, leads to
the following static checker warning, as reported by Dan Carpenter in
https://lists.freedesktop.org/archives/dri-devel/2016-February/101987.html
drivers/gpu/drm/amd/amdgpu/amdgpu_display.c:127 amdgpu_flip_work_func() warn: should this be 'repcnt == -1'

drivers/gpu/drm/amd/amdgpu/amdgpu_display.c:136 amdgpu_flip_work_func() error: double unlock 'irqsave:flags'
This patch fixes both reported problems:
Change post-decrement of repcnt to pre-decrement, so
it can't underflow anymore, but still performs up to
three repetitions - three is the maximum one could
expect in practice.
Move the spin_unlock_irqrestore to where it actually
belongs.

Currently host1x-instanciated devices have their dma_ops left to NULL,
which makes any DMA operation (like buffer import) on ARM64 fallback
to the dummy_dma_ops and fail with an error.
This patch calls of_dma_configure() with the host1x node when creating
such a device, so the proper DMA operations are set.

With full-ppgtt, it takes the GPU an eon to traverse the entire 256PiB
address space, causing a loop to be detected. Under the current scheme,
if ACTHD walks off the end of a batch buffer and into an empty
address space, we "never" detect the hang. If we always increment the
score as the ACTHD is progressing then we will eventually timeout (after
~46.5s (31 * 1.5s) without advancing onto a new batch). To counter act
this, increase the amount we reduce the score for good batches, so that
only a series of almost-bad batches trigger a full reset. DoS detection
suffers slightly but series of long running shader tests will benefit.
Based on a patch from Chris Wilson.

Now that the mess with AUX clock divder rounding is sorted out and
we have both cdclk and rawclk cached in dev_priv, we can clean up
the .get_aux_clock_divider() functions a bit.
The main thing here is just calling ilk_get_aux_clock_divider()
from hsw_get_aux_clock_divider() except for the LPT:H special
case.
We could go further and call g4x_get_aux_clock_divider() from
ilk_get_aux_clock_divider() for the PCH ports, but I'm sure Jani
would object, so leave that be.
While at it repeat the comment where the AUX clock comes from

Generalize rawclk handling by storing it in dev_priv.
Presumably our hrawclk readout works at least for CTG and ELK
since we've been using it for DP AUX on those platforms. There
are no real docs anymore after configdb vanished, so the only
reference is the public CTG GMCH spec. What bits are listed in
that doc match our code. The ELK GMCH spec have no relevant
details unfortunately.
The PNV situation is less clear. Starting from
commit aa17cdb4f836 ("drm/i915: initialize backlight max from VBT")
we assume that the CTG/ELK hrawclk readout works for PNV as well.
At least the results *seem* reasonable for one PNV machine (Lenovo
Ideapad S10-3t). Sadly the PNV GMCH spec doesn't have the goods on
the relevant register either.
So let's keep assuming it works for PNV,ELK,CTG and read it out on
those platforms. G33 also has hrawclk according to some notes
in BSpec, but we don't actually need it for anything, so let's not
even try to read it out there.

Big ticket items are hdmi support for 8996 (aka snapdragon 820), and
adreno 430 support. Also one more small uapi addition to support
timestamp queries.

Looks like this code does not need to wait atomically since it
otherwise takes the mutex.

Currently the wait_for_atomic_us only allows for a jiffie
timeout granularity which is not nice towards callers
requesting small micro-second timeouts.
Re-implement it so micro-second timeout granularity is really
supported and not just in the name of the macro.
This has another beneficial side effect that it improves
"gem_latency -n 100" results by approximately 2.5% (throughput
and latencies) and 3% (CPU usage). (Note this improvement is
relative to not yet merged execlist lock uncontention patch
which moves the CSB MMIO outside this lock.)
It also shrinks some hot functions like fw_domains_get by a
tiny 3%.
v2:
* Warn when used from non-atomic context (if possible).
* Warn on too long atomic waits.
v3:
* Added comment explaining CONFIG_PREEMPT_COUNT.
* Fixed pre-processor indentation.
(Chris Wilson)
v4:
* Commit msg update (gem_latency) and rebase.
v5:
* Commit message re-wording.
* Added comment about no need for double cond check. (Chris Wilson)
