ironlake_{enable,disable}_display_irq() each just call
ilk_update_display_irq() so let's make them static inlines.
While at it s/ironlake/ilk/ to make things shorter, and a bit more
consistent with the ibx functions.

shooting the messenger while the debugging for why Sonika's commit
triggered the errors was still in progress.
It looks like we need to read and acknowledge the PCH_PORT_HOTPLUG
register even though the hotplug trigger indicates there isn't a hotplug
irq to handle. The PCH doesn't seem to really ack the the interrupt to
the CPU unless we touch the hotplug register.

On some machines the CRT connector may be fused off. The weird thing
about this setup is that the ADPA register works otherwise normally,
except the enable bit is hardwired to 0. No one knows of any fuse
register that would tell us if this is the case, so the only thing we
can do (apart from a blacklist) is to try and set the enable bit and see
if it sticks. If not, we don't register the connector at all. Obviously
if the bit is already set when loading the driver we can just assume it
works.
I've smoke tested this approach on several machines (GMCH and PCH),
some with actual CRT connectors, some with shadow connectors, and
obviously the machine (IVB) with the fused off connector. So far
I've not seen any ill effects from this probe.
The main benefit is that we can actually run igt on machines with
fused off connectors, without totally upsetting the state checker.

We sometimes get a spurious CPU pipe underrun somewhere between
enabling port A and enabling vdd for the panel. Observed on both
ILK and IVB with port A eDP. Suppress FIFO underrun reporting
around the port and vdd enable to avoid the dmesg errors.
Not sure if port D eDP would suffer from the same issue, but assume
that it doesn't until proven differently.

We still get spurious pipe underruns on ILK/SNB/IVB under two
circumstances when dealing with PCH ports:
* When the pipe has been disabled, but FDI RX/TX is still enabled
* During FDI link training
Both cases seem to happen at least when we do VGA+HDMI cloning
from the same pipe. I don't think I've seen them when not cloning,
but can't be 100% sure.
Disable underrun reporting around those places to eliminate the
dmesg errors.

Whenever DMC firmware put the HW into DC State a bunch
of registers including this perf counter is reset to 0.
Even with PSR active and working we could still read
"Performance_Counter: 0" what will misslead people to believe
PSR is broken. For instance on SKL we can only see PC10
residency with screen on if PSR is working properly.
However Performance_Counter was showing 0.
Even if it restored properly on DC6 exit we don't want to
give users the wrong impression that PSR is not working
while we know for sure it is.
So, it is better to remove this counter information while
we don't have a better way to track PSR residency.

When we introduced PSR we let LPSP masked allowing us to get PSR
independently from the audio runtime PM. However in one of the
attempts to get PSR enabled by default one user reported one specific
case where he would miss screen updates if scrolling the firefox in a
Gnome environment when i915 runtime pm was enabled. So for
this specific case that (I could never create an i-g-t test case)
we decided to remove the LPSP mask and let HW tracking taking care of
this case. The mask got removed later by my
commit 09108b90f04 ("drm/i915: PSR: Remove Low Power HW tracking mask.")
So we started depending on audio driver again, what is bad.
With previous commit
"drm/i915: PSR: Let's rely more on frontbuffer tracking."
we transfered the PSR exit responsability totally to SW frontbuffer
tracking. So now can safelly shut off a bit the HW tracking, or
at least this case that makes us to depend on other drivers.

the bugzilla entries.
v3: Another attempt to improve commit message.

The ultimate goal here is to remove the dependency we
currently have on audio driver power to get PSR working.
Since with audio driver runtime PM disabled the Hardware tracking
believes graphics is fully active and prevent PSR Entry, or
in other words continuously exit PSR.
So, the idea is to transfer the PSR exit responsability
from the HW tracking to the SW tracking (frontbuffer tracking),
who is really mature right now.
However with LPSP masked out there might be cases where we could
miss exit from HW tracking since it can be relying on this,
like a specific case reported at our mailing list who
user reported he would miss screen updates if scrolling firefox
in a Gnome environment when i915 runtimepm was enabled.
So before masking out LPSP again to make us independent from
the audio driver we need to make sure that all our cases
are coverred from the frontbuffer tracking perspective,
where the flush means invalidate and flush.
Without this patch for HSW, BDW and SKL we just do the
invalidate part when the flush wasn't originated by a page flip
because we were trusting the HW tracking for the flip case.
So let's rely more on frontbuffer tracking and do the
invalidation regardless the origin as expected for all platforms.
v2: Improve commit message as suggested by Paulo.
v3: Another attempt to let commit message more clear.

Commit (89251b17) intended to remove this line and let only one
DP_PSR_EN_CFG set, but it was wrong and this call is now duplicated
at the code.
Also "& ~DP_PSR_MAIN_LINK_ACTIVE" doesn't do anything at all. It
was like that since I introduced this call but probably the idea
was to be informative and make clear statement that we were not using
the link standby. So it is better to remove this one here and let
the code a bit cleaner.

drm/i915: Clean up associated VMAs on context destruction
Added a warning based on an incorrect assumption that all VMAs
in a VM will be on the inactive list at the point last reference
to a context and VM is dropped.
This is not true because i915_gem_object_retire__read will not
put VMA on the inactive list until all activities on the object
in question (in all VMs) have been retired.
As a consequence, whether or not a context/VM will be destroyed
with its VMAs still on the active list, can depend on completely
unrelated activities using the same object from a different
context or engine.

Currently if intelfb_create() errors out, it unrefs the bo even though
the fb now owns that reference. (Spotted by Ville Syrjälä.) We should
unref the fb instead of the bo.
However the fb was not necessarily allocated by intelfb_create(),
it could be inherited from BIOS (the fb struct was then allocated by
dev_priv->display.get_initial_plane_config()) and be in active use by
a crtc. In this case we should call drm_framebuffer_remove() instead
of _unreference() to also disable the crtc.
Daniel Vetter suggested that "fbdev teardown code will take care of it.
The correct approach is probably to not unref anything at all".
But if fbdev initialization fails, the fbdev isn't torn down and
occupies memory even though it's unusable. Therefore clobber it in
intel_fbdev_initial_config(). (Currently we ignore a negative return
value there.) The idea is that if fbdev initialization fails, the driver
behaves as if CONFIG_DRM_FBDEV_EMULATION wasn't set. Should X11 manage
to start up without errors, it will at least be able to use the memory
that would otherwise be hogged by the unusable fbdev.
Also, log errors in intelfb_create().
Don't call async_synchronize_full() in intel_fbdev_fini() when called
from intel_fbdev_initial_config() to avoid deadlock.
v2: Instead of calling drm_framebuffer_unreference() (if fb was not
inherited from BIOS), call intel_fbdev_fini().
v3: Rebase on e00bf69644ba (drm/i915: Move the fbdev async_schedule()
into intel_fbdev.c), call async_synchronize_full() conditionally
instead of moving it into i915_driver_unload().

intelfb_create() is called once on driver initialization. If it fails,
ifbdev->helper.fbdev, ifbdev->fb or ifbdev->fb->obj may be NULL.
Further up in the call stack, intel_fbdev_initial_config() calls
intel_fbdev_fini() to tear down the ifbdev on failure. This calls
intel_fbdev_destroy() which dereferences ifbdev->fb. Fix the ensuing
oops.
Also check in these functions if ifbdev is not NULL to avoid oops:
i915_gem_framebuffer_info() is called on access to debugfs file
"i915_gem_framebuffer" and dereferences ifbdev, ifbdev->helper.fb
and ifbdev->helper.fb->obj.
intel_connector_add_to_fbdev() / intel_connector_remove_from_fbdev()
are called when registering / unregistering an mst connector and
dereference ifbdev.
v3: Drop additional null pointer checks in intel_fbdev_set_suspend(),
intel_fbdev_output_poll_changed() and intel_fbdev_restore_mode()
since they already check if ifbdev is not NULL, which is sufficient
now that intel_fbdev_fini() is called on initialization failure.

drm/i915: Add a partial GGTT view type
on Tvrtko's request, but without a clear justification. Rotated views
are also not checking for matching paramters in i915_ggtt_view_equal,
which seems like a bug. But this patch here doesn't change that.

This was totally lost when I originally created the atomic helpers.
We probably should also check possible_clones in the helpers, but
since the legacy ones didn't do that this is for a separate patch.

commit 6764e9f8724f1231b4deac53b9a82286ac0830e7
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date: Thu Aug 27 15:44:06 2015 +0200
drm/i915: skip modeset if compatible for everyone.
Bring back the i915.fastboot module parameter, disabled by default, due
to backlight regression on Chromebook Pixel 2015.
Apparently the firmware of the Chromebook in question enables the panel
but disables backlight to avoid a brief garbage scanout upon loading the
kernel/module. With fastboot, we leave the backlight untouched, in this
case disabled. The user would have to do a modeset (i.e. not just crank
up the brightness) to enable the backlight.
There is no clean fix readily available, so get back to the drawing
board by reverting.
[N.B. The reference below is for when the thread was included on public
lists, and some of the context had already been dropped by then.]

The cursor code may be entered with file_priv == NULL && handle == NULL.
The problem was introduced by:
"bf89209 drm/mga200g: Hold a proper reference for cursor_set"
which calls drm_gem_object_lookup(dev, file_priv...). Previously this wasn't
a problem because we checked the handle. Move the check early in the function
can fix the problem.

MISSING_CASE() would have been useful to track down a recent problem in
intel_display_port_aux_power_domain(), so add it there and a few related
helpers. This was also suggested by Ville in his review of the latest

Due to the current sharing of the DDI encoder between DP and HDMI
connectors we can run the DP detection after the HDMI detection has
already set the shared encoder's type. For now solve this keeping the
current behavior and running the detection in this case too. For a proper
solution Ville suggested to split the encoder into an HDMI and DP one, that
can be done as a follow-up.
This issue triggers the WARN in intel_display_port_aux_power_domain() and
was introduced in:
