4a192c7e8b drm/i915/gtt: Free unused page tables on unbind the context
As we cannot reliably change used page tables while the context is
active, the earliest opportunity we have to recover excess pages is when
the context becomes idle. So whenever we unbind the context (it must be
idle, and indeed being evicted) free the unused ptes.

549fe88bf7 drm/i915/gtt: Lazily allocate page directories for gen7
As we were only supporting aliasing_ppgtt on gen7 for some time, we
saved a few checks by preallocating the page directories on creation.
However, since we need 2MiB of page directories for each ppgtt, to
support arbitrary numbers of user contexts, we need to be more prudent
in our allocations, and defer the page allocation until it is used. We
don't recover unused pages yet as we found that doing so on the fly
(i.e. altering TLB entries) would confuse the GPU.

1fd00c0fae drm/i915: Declare the driver wedged if hangcheck makes no progress
Hangcheck is our back up in case the GPU or the driver gets stuck. It
detects when the GPU is not making any progress and issues a GPU reset.
However, if the driver is failing to make any progress, we can get
ourselves into a situation where we continually try resetting the GPU to
no avail. Employ a second timeout such that if we continue to see the
same seqno (the stalled engine has made no progress at all) over the
course of several hangchecks, declare the driver wedged and attempt to
start afresh.

5db1d4ea91 drm/i915/execlists: Push the tasklet kick after reset to reset_finish
In the unlikely case where we have failed to keep submitting to the GPU,
we end up with the ELSP queue empty but a pending queue of requests.
Here, we skip the per-engine reset as there is no guilty request, but in
doing so we also skip the engine restart leaving ourselves with a
permanently hung engine. A quick way to recover is by moving the tasklet
kick to execlists_reset_finish() (from init_hw). We still emit the error
on hanging, so the error is not lost but we should be able to recover.

51a9f6dfc0 drm/i915: Turn off g4x DP port in .post_disable()
While Bspec doesn't list a specific sequence for turning off the DP port
on g4x we are getting an underrun if the port is disabled in the
.disable() hook. Looks like the pipe stops when the port stops, and by
that time the plane disable may not have completed yet. Also the plane(s)
seem to end up in some wonky state when this happens as they also signal
another underrun immediately after we turn them back on during the next
enable sequence.

We could add a vblank wait in .disable() to avoid wedging the planes,
but I assume we're still tripping up the pipe in some way. So it seems
better to me to just follow the ILK+ sequence and turn off the DP port
in .post_disable() instead. This sequence doesn't seem to suffer from
this problem. Could be it was always the intended sequence for DP and
the gen4 bspec was just never updated to include it.

Originally we used the bad sequence even on ilk+, but I changed that
in commit 08aff3fe26 ("drm/i915: Move DP port disable to post_disable
for pch platforms") as it was causing issues on those platforms as well.
I left out g4x then only because I didn't have the hardware to test it.
Now that I do it's fairly clear that the ilk+ sequence is also the
right choice for g4x.

132c27c97c drm/i915: Fix PIPESTAT irq ack on i965/g4x
On i965/g4x IIR is edge triggered. So in order for IIR to notice that
there is still a pending interrupt we have to force and edge in ISR.
For the ISR/IIR pipe event bits we can do that by temporarily
clearing all the PIPESTAT enable bits when we ack the status bits.
This will force the ISR pipe event bit low, and it can then go back
high when we restore the PIPESTAT enable bits.

This avoids the following race:
1. stat = read(PIPESTAT)
2. an enabled PIPESTAT status bit goes high
3. write(PIPESTAT, enable|stat);
4. write(IIR, PIPE_EVENT)

The end result is IIR==0 and ISR!=0. This can lead to nasty
vblank wait/flip_done timeouts if another interrupt source
doesn't trick us into looking at the PIPESTAT status bits despite
the IIR PIPE_EVENT bit being low.

Before i965 IIR was level triggered so this problem can't actually
happen there. And curiously VLV/CHV went back to the level triggered
scheme as well. But for simplicity we'll use the same i965/g4x
compatible code for all platforms.

8fc0aa6eaa drm/i915/ddi: Check transcoder instead of port when setting HDMI infoframe
The only requirement by BSpec for setting the HDMI infoframes is on DDI
platforms to do that before enabling the HDMI transcoder function, see
VIDEO_DIP_CTL bit 16. Accordingly check for the transcoder function
disabled state instead of the port's disabled state on DDI platforms.
This is needed by the next patch as it will set the infoframe during
crtc disabling where the port is still enabled.

5422b37c90 drm/i915/psr: Kill delays when activating psr back.
The immediate enabling was actually not an issue for the
HW perspective for core platforms that have HW tracking.
HW will wait few identical idle frames before transitioning
to actual psr active anyways.

Now that we removed VLV/CHV out of the picture completely
we can safely remove any delays.

Note that this patch also remove the delayed activation
on HSW and BDW introduced by commit 'd0ac896a477d
("drm/i915: Delay first PSR activation.")'. This was
introduced to fix a blank screen on VLV/CHV and also
masked some frozen screens on other core platforms.
Probably the same that we are now properly hunting and fixing.

v2:(DK): Remove unnecessary WARN_ONs and make some other
         VLV | CHV more readable.
v3: Do it regardless the timer rework.
v4: (DK/CI): Add VLV || CHV check on cancel work at psr_disable.
v5: Kill remaining items and fully rework activation functions.
v6: Rebase on top of VLV/CHV clean-up and keep the reactivation
    on a regular non-delayed work to avoid extra delays on exit
    calls and allow us to add few more safety checks before
    real activation.

a2bbf71483 drm/i915/gtt: Only keep gen6 page directories pinned while active

For the kernel_context (and thus aliasing_ppgtt), it remains pinned at
all times, as the kernel_context itself is pinned at all times.

e4dd27aadd drm/i915: Allow DBLSCAN user modes with eDP/LVDS/DSI
When encountering a connector with the scaling mode property both
intel and modesetting ddxs sometimes add tons of DBLSCAN modes
to the output's mode list. The idea presumably being that since the
output will be going through the panel fitter anyway we can pretend
to use any kind of mode.

Sadly that means we can't reject user modes with the DBLSCAN flag
until we know whether we're going to be using the panel's native
mode or the user mode directly. Doing otherwise means X clients using
xf86vidmode/xrandr will get a protocol error (and often self
terminate as a result) when the kernel refuses to use the requested
mode with the DBLSCAN flag.

To undo the regression we'll move the DBLSCAN checks into the
connector->mode_valid() and encoder->compute_config() hooks.

so let's pick the last entry as the default for now
to stay consistent with older platform like CNL.

e9e7dc4144 drm/i915/gtt: Make gen6 page directories evictable
Currently all page directories are bound at creation using an
unevictable node in the GGTT. This severely limits us as we cannot
remove any inactive ppgtt for new contexts, or under aperture pressure.
To fix this we need to make the page directory into a first class and
unbindable vma. Hence, the creation of a custom vma to wrap the page
directory as opposed to a GEM object.

In this patch, we leave the page directories pinned upon creation.

3d6d62eae7 drm/i915/guc: Add support for define guc_log_size in megabytes.
At this moment we can define GuC logs sizes only using pages.
But GuC also allows use for this values expressed in megabytes.
Lets add support for define guc_log_size in megabytes when we
debug of GuC.

- merge statements in guc_ctl_log_params_flags() (Michał Wajdeczko)
v3:
