Fixes a regression introduced by 060810d7abaabca "drm/nouveau: fix locking
issues in page flipping paths". chan->cli->mutex is unlocked a second time
in the fail_unreserve path, fix this by moving mutex_unlock down.

There appear to be a crop of new hardware where the vbios is not
available from PROM/PRAMIN, but there is a valid _ROM method in ACPI.
The data read from PCIROM almost invariably contains invalid
instructions (still has the x86 opcodes), which makes this a low-risk
way to try to obtain a valid vbios image.

drm/i915: Reorganize intel_enable_ppgtt
As the i915.enable_ppgtt is read-only it cannot be changed after the
module is loaded and so we can perform an early sanitization of the
values.
v2:
- Add comment and pimp commit message (Chris)
- Use the param consistently (Jani)
v3:
- Fix init sequence on pre-gen6 by moving the sanitize_ppgtt call to
gtt_init. Fixes boot hangs on pre-gen6.
- Add a debug output for the sanitize ppgtt mode.

Depending on the SDVO output_flags SDVO may have multiple connectors
linking to the same encoder (in intel_connector->encoder->base).
Only one of those connectors should be active (ie link to the encoder
thru drm_connector->encoder).
If intel_connector_break_all_links() is called from intel_sanitize_crtc()
we may break the crtc connection of an encoder thru an inactive connector
in which case intel_connector_break_all_links() will not be called again
for the active connector if this happens to come later in the list due to:
if (connector->encoder->base.crtc != &crtc->base)
continue;
in intel_sanitize_crtc().
This will however leave the drm_connector->encoder linkage for this
active connector in place. Subsequently this will cause multiple
warnings in intel_connector_check_state() to trigger and the driver
will eventually die in drm_encoder_crtc_ok() (because of crtc == NULL).
To avoid this remove intel_connector_break_all_links() and move its
code to its two calling functions: intel_sanitize_crtc() and
intel_sanitize_encoder().
This allows to implement the link breaking more flexibly matching
the surrounding code: ie. in intel_sanitize_crtc() we can break the
crtc link separatly after the links to the encoders have been
broken which avoids above problem.
This regression has been introduced in:

drm/i915: read out the modeset hw state at load and resume time
so goes back to the very beginning of the modeset rework.
v2: This patch takes care of the concernes voiced by Chris Wilson
and Daniel Vetter that only breaking links if the drm_connector
is linked to an encoder may miss some links.
v3: move all encoder handling to encoder loop as suggested by
Daniel Vetter.

The way the tile mode array index was calculated only makes sense for
the CIK specific macrotile mode array. For SI, we need to use one of the
tile mode array indices reserved for displayable surfaces.
This happened to result in correct display most if not all of the time
because most of the SI tiling modes use the same number of banks.

Testing the update pending bit directly after issuing an
update is nonsense cause depending on the pixel clock the
CRTC needs a bit of time to execute the flip even when we
are in the VBLANK period.
This is just a non invasive patch to solve the problem at
hand, a more complete and cleaner solution should follow
in the next merge window.

drm: Add drm_crtc_init_with_planes() (v2)
The result was that we've unref'ed the fb for the primary plane twice,
leading to a use-after free bug. This is because the drm core will
already set crtc->primary->fb to NULL and do the unref for us, and the
crtc disable hook is called by the drm crtc helpers for exactly this
case.
Aside: Now that the fbdev helpers clean up planes there's no longer a
need to do this in drivers. So this could probably be nuked entirely
in linux-next.

The hw cursor is relatively adept at triggering underflows, which
manifest as a "blue flash" (since blue is configured as the underflow
color). Juggle a few things around to tighten up the timing for setting
cursor registers in DONE irq.
And most importantly, don't ever disable the hw cursor. Instead flip it
to a blank/empty cursor. This seems far more reliable, as even simply
clearing the cursor-enable bit (with no other updates in previous/
following frames) can in some cases cause underflow.

Since X11 is going to create an XR24 fb, if the pixel formats do not
match then crtc helpers will think it is a full modeset even if mode is
the same, which prevents smooth/flickerless handover from fbcon/plymouth
to X11.

drm/i915: disable rings before HW status page setup
we reordered stopping the rings to do so before we set the HWS register.
However, there is an extra workaround for g45 to reset the rings twice,
and for consistency we should apply that workaround before setting the
HWS to be sure that the rings are truly stopped.

The status bits are unconditionally set, the control bits only enable
the actual interrupt generation. Which means if we get some random
other interrupts we'll bogusly complain about them.
So restrict the WARN to platforms with a sane hotplug interrupt
handling scheme. And even more important also don't attempt to process
the hpd bit since we've detected a storm already. Instead just clear
the bit silently.
This WARN has been introduced in

When PPGTT was disabled by default, the patch also prevented the user
from overriding this behavior via module parameter. Being able to test
this on arbitrary kernels is extremely beneficial to track down the
remaining bugs. The patch that prevented this was:

If I unplug the eDP monitor, the BIOS of my machine will enable the
VDD bit, then when the driver loads it will think VDD is enabled. It
will detect that the eDP is not enabled and return false from
intel_edp_init_connector. This will trigger a call to
edp_panel_vdd_off_sync(), which trigger a WARN saying that the
refcount of the power domain is less than zero.
The problem happens because the driver gets a refcount whenever it
enables the VDD bit, and puts the refcount whenever it disables the
VDD bit. But on this case, the BIOS enabled VDD, so all we do is to
call put() without calling get() first, so the code added is there to
make sure we always have the get() in case the BIOS enabled the bit.
This regression was introduced in

... our current modeset code isn't good enough yet to handle this. The
scenario is:
1. BIOS sets up a cloned config with lvds+external screen on the same
pipe, e.g. pipe B.
2. We read out that state for pipe B and assign the gmch_pfit state to
it.
3. The initial modeset switches the lvds to pipe A but due to lack of
atomic modeset we don't recompute the config of pipe B.
-> both pipes now claim (in the sw pipe config structure) to use the
gmch_pfit, which just won't work.

drm/i915: Reject >165MHz modes w/ DVI monitors
the driver started to filter out display modes which exceed the
single-link DVI 165Mz dotclock limits when the monitor doesn't report
itself as being HDMI compliant. The intent was to filter out all
EDID derived modes that require dual-link DVI to operate since we
don't support dual-link.
However the patch went a bit too far and also causes the driver to reject
such modes even when specified by the user. Normally we don't check the
sink limitations when setting a mode from the user. This allows the user
to specify any mode whether the sink reports to support it or not. This
can be useful since often the sinks support more modes than they report
in the EDID.
So relax the checks a bit, and apply the single-link DVI dotclock limit
only when filtering the mode list, and ignore the limit when setting
a user specified mode.
