In the cloned case, changing just one output but keeping the other, the
pipe state won't change and intel_crtc_update_dpms will be a nop, but we
still need to update the dpms state of the output being changed.
Only dvo, sdvo and crt are cloneable, so only those three have special
dpms functions.

We can use this for fetching encoder specific pipe_config state, like
mode flags, adjusted clock, etc.
Just used for mode flags atm, so we can check the pipe config state at
mode set time.

Backmerge Linux 3.10-rc2 since the various (rather trivial) conflicts
grew a bit out of hand. intel_dp.c has the only real functional
conflict since the logic changed while dev_priv->edp.bpp was moved
around.
Also squash in a whitespace fixup from Ben Widawsky for
i915_gem_gtt.c, git seems to do something pretty strange in there
(which I don't fully understand tbh).

drm_i915_private is getting bigger and bigger when adding new vbt stuff.
So, the better way of getting drm_i915_private organized is to create
a special structure for vbt stuff.

As promised a stash of (mostly) fixes. Two pieces of non-fixes included:
- A notch more gtt refactoring from Ben, beating to death with igt in our
nightly testing.
- Support for display display-less server chips (again from Ben). New hw
support which is only likely to break itself ;-)
Otherwise just tons of fixes:
- hpd irq storm mitigation from Egbert Eich. Your -next tree already has
the infrastructure, this here just supplies the logic.
- sdvo hw state check fix from Egbert Eich
- fb cb tune settings for the pch pll clocks on cpt/ppt
- "Bring a bigger gun" coherence workaround for multi-threade, mulit-core

When an encoder is shared on several connectors there is only
one hotplug line, thus this line needs to be shared among these
connectors.
If HPD detect only works reliably on a subset of those connectors,
we want to poll the others. Thus we need to make sure that storm
detection doesn't mess up the settings for those connectors.
Therefore we store the settings in the intel_connector struct and
restore them from there.
If nothing is set but the encoder has a hpd_pin set we assume this
connector is hotplug capable.
On init/reset we make sure the polled state of the connectors
is (re)set to the default value, the HPD interrupts are marked
enabled.

Since I expect Linus to open the merge window in about a week I guess this

The big item here is though the introduction of pipe_config to properly
pre-compute the desired modeset state before touching the hw. Together
with some very basic support to read out the current config from the hw
and compare the state with the sw tracking. This is all prep work for more
reliable fastboot, atomic modesets and other cool features. Stuff
converted to the new world includes:
- Most simple pipe attributes (reduce color range, pixel multiplier).
- Pipe bpp/dither handling.
- Some convenience flags like ->has_pch_encoder to simplify the code flow.

For 3.10 I have a bunch of fixes queued up and I plan to send them all out

so that we don't but feature-y stuff in there, too. The main thing I'd
like to sneak in is Egbert's hpd irq storm handling, which should be
pretty low-risk since all the infrastructure work has landed already. I
also have the oops fix pending, but that only mustered review before the

it some more testing before forwarding.

This is used way too often in the enable/disable paths. And will
be even more useful in the future.
Note that correct semantics of this change highly depend upon
correct updating of intel_crtc->config: Like with all other
modeset state, we need to call ->disable with the old config,
but ->mode_set and ->enable with the new config.
v2: Do not yet use the flag in the ->disable callbacks - atm we don't
yet have support for the information stored in the pipe_config in the
hw state readout code, so this will be wrong at boot-up/resume.
v3: Rebased on top of the hdmi/dp ddi encoder merging.
v4: Fixup stupid rebase error which lead to a NULL vfunc deref.

drm/i915: Turn off hsync and vsync on ADPA when disabling crt
properly disabled the hsync/vsync logic at disable time, but neglected
to re-enable them at enable time.
v2: In the enable hook, restore the connector's expected DPMS level
instead of forcing ON. Do this by stashing a back pointer to the

To clean up hotplug support we add a new enum to intel_encoder:
enum hpd_pin. It allows the encoder to request a hpd line but leave
the details which IRQ is responsible on which chipset generation
to i915_irq.c.
This way requesting hotplug support will become really simple on
the encoder/connector level.

So here's my promised pile of fixes for 3.9. I've dropped the core prep
patches for vt-switchless suspend/resume as discussed on irc. Highlights:
- Fix dmar on g4x. Not really gfx related, but I'm fed up with getting
blamed for dmar crapouts.
- Disable wc ptes updates on ilk when dmar is enabled (Chris). So again,
dmar, but this time gfx related :(
- Reduced range support for hsw, using the pipe CSC (Ville).
- Fixup pll limits for gen3/4 (Patrick Jakobsson). The sdvo patch is
already confirmed to fix 2 bug reports, so added cc: stable on that one.
- Regression fix for 8bit fb console (Ville).
- Preserve lane reversal bits on DDI/FDI ports (Damien).
- Page flip vs. gpu hang fixes (Ville). Unfortuntely not quite all of
them, need to decide what to do with the currently still in-flight ones.
- Panel fitter regression fix from Mika Kuoppala (was accidentally left on
on some pipes with the new modset code since 3.7). This also improves
the modeset sequence and might help a few other unrelated issues with
lvds.
- Write backlight regs even harder ... another installement in our eternal
fight against the BIOS and backlights.
- Fixup lid notifier vs. suspend/resume races (Zhang Rui). Prep work for
new ACPI stuff, but closing the race itself seems worthwile on its own.
- A few other small fixes and tiny cleanups all over.
Lots of the patches are cc: stable since I've stalled on a few
not-so-important fixes for 3.8 due to the grumpy noise Linus made.

The FDI link has supported link reversal to make the PCB layout
engineer's life easier for quite a while and we have always presered
this bit as we programmed FDI_RX_CTL with a read/modify/write sequence.
We're trying to take a bit more control over what the BIOS leaves in
various register and with the introduction of DDI, started to program
FDI_RX_CTL fully.
There's a fused bit to indicate DMI link reversal and FDI defaults to
mirroring that configuration. We have a bit to override that behaviour
that we need to preserve from the BIOS.

If we fail to set the bit when needed we get some nice FDI link

While we don't really know how to properly choose whether we need to
set the bit or not (VBT?), just read the initial value set by the BIOS
and store it for later usage.

The bit doesn't stick, and the output is always cloned from pipe A,
even when it's supposed to scan out from pipe B.
Shuts up annoying warnings from the modeset-rework, too.
I've noticed that with this patch we know get and unknown connection
state since the code can't find a suitable pipe for load detection.
But that beats the previous state of affairs, where it tried to use
pipe B, actually used pipe A and concluded that something is connected
(although it's the LVDS on pipe A and nothing on the VGA connector on
pipe B).
I've tried to make load detect work by remapping the pipe->planes
stuff, so that crtc 0 will use pipe B and hence we still have
something left for load-detect on pipe A. But alas, that upset the hw
a bit.
So there's still some things to figure out, but this here will at
least paper over some of the problems.

To extract a bit of code call drm_mode_config_reset both on resume

The DPLL multipiler is set up in intel_display.c:i9xx_update_pll()
called from i9xx_crtc_mode_set().
There the DPLL multiplier is adjusted so that the SDVO gets a sufficient
bus clock.
When cloning a CRTC between an SDVO driven encoder and the standard
DAC the DAC setup code reseted the multiplier value to 1 thus undoing
the correct setup. There is no need to touch the multiplier in the DAC
setup code: the correct value (i.e. 1 in case no SDVO encoder is used)
is set by i9xx_update_pll() already.
A comment at the code suggested that this code is a left over from the
days when there was no setup for clone modes.

As a quick reference I'll detail the motivation and design of the new code a
bit here (mostly stitched together from patchbomb announcements and commits
introducing the new concepts).
The crtc helper code has the fundamental assumption that encoders and crtcs can
be enabled/disabled in any order, as long as we take care of depencies (which
means that enabled encoders need an enabled crtc to feed them data,
essentially).
Our hw works differently. We already have tons of ugly cases where crtc code
enables encoder hw (or encoder->mode_set enables stuff that should only be
enabled in enocder->commit) to work around these issues. But on the disable
side we can't pull off similar tricks - there we actually need to rework the
modeset sequence that controls all this. And this is also the real motivation
why I've finally undertaken this rewrite: eDP on my shiny new Ivybridge
Ultrabook is broken, and it's broken due to the wrong disable sequence ...
The new code introduces a few interfaces and concepts:
- Add new encoder->enable/disable functions which are directly called from the
crtc->enable/disable function. This ensures that the encoder's can be
enabled/disabled at a very specific in the modeset sequence, controlled by our
platform specific code (instead of the crtc helper code calling them at a time
it deems convenient).
- Rework the dpms code - our code has mostly 1:1 connector:encoder mappings and
does support cloning on only a few encoders, so we can simplify things quite a
bit.
- Also only ever disable/enable the entire output pipeline. This ensures that
we obey the right sequence of enabling/disabling things, trying to be clever
here mostly just complicates the code and results in bugs. For cloneable
encoders this requires a bit of special handling to ensure that outputs can
still be disabled individually, but it simplifies the common case.
- Add infrastructure to read out the current hw state. No amount of careful
ordering will help us if we brick the hw on the initial modeset setup. Which
could happen if we just randomly disable things, oblivious to the state set up
by the bios. Hence we need to be able to read that out. As a benefit, we grow a
few generic functions useful to cross-check our modeset code with actual hw
state.
With all this in place, we can copy&paste the crtc helper code into the
drm/i915 driver and start to rework it:
- As detailed above, the new code only disables/enables an entire output pipe.
As a preparation for global mode-changes (e.g. reassigning shared resources) it
keeps track of which pipes need to be touched by a set of bitmasks.
- To ensure that we correctly disable the current display pipes, we need to
know the currently active connector/encoder/crtc linking. The old crtc helper
simply overwrote these links with the new setup, the new code stages the new
links in ->new_* pointers. Those get commited to the real linking pointers once
the old output configuration has been torn down, before the ->mode_set
callbacks are called.
- Finally the code adds tons of self-consistency checks by employing the new hw
state readout functions to cross-check the actual hw state with what the
datastructure think it should be. These checks are done both after every
modeset and after the hw state has been read out and sanitized at boot/resume
time. All these checks greatly helped in tracking down regressions and bugs in
the new code.
With this new basis, a lot of cleanups and improvements to the code are now
possible (besides the DP fixes that ultimately made me write this), but not yet
done:
- I think we should create struct intel_mode and use it as the adjusted mode
everywhere to store little pieces like needs_tvclock, pipe dithering values or
dp link parameters. That would still be a layering violation, but at least we
wouldn't need to recompute these kinds of things in intel_display.c. Especially
the port bpc computation needed for selecting the pipe bpc and dithering
settings in intel_display.c is rather gross.
- In a related rework we could implement ->mode_valid in terms of ->mode_fixup
in a generic way - I've hunted down too many bugs where ->mode_valid did the
right thing, but ->mode_fixup didn't. Or vice versa, resulting in funny bugs
for user-supplied modes.
- Ditch the idea to rework the hdp handling in the common crtc helper code and
just move things to i915.ko. Which would rid us of the ->detect crtc helper
dependencies.
- LVDS wire pair and pll enabling is all done in the crtc->mode_set function
currently. We should be able to move this to the crtc_enable callbacks (or in
the case of the LVDS wire pair enabling, into some encoder callback).
Last, but not least, this new code should also help in enabling a few neat
features: The hw state readout code prepares (but there are still big pieces
missing) for fastboot, i.e. avoiding the inital modeset at boot-up and just
taking over the configuration left behind by the bios. We also should be able
to extend the configuration checks in the beginning of the modeset sequence and
make better decisions about shared resources (which is the entire point behind
the atomic/global modeset ioctl).

Atm we can only check the connector state after a dpms call - while

ill-defined for proper checking. But the idea is very much to call
this check from the modeset code, too.
v2: Fix dpms check and don't presume that if the hw isn't on that it

Note that even though this connector is cloneable we still can use the

frob the exact same hw state.

Yeah, big patch but I couldn't come up with a neat idea of how to
split it up further, that wouldn't break dpms on cloned configs
somehow. But the changes in dvo/sdvo/crt are all pretty much
orthonogal, so it's not too bad a patch.
These are the only encoders that support cloning, which requires a few
special changes compared to the previous patches.
- Compute the desired state of the display pipe by walking all
connected encoders and checking whether any has active connectors.
To make this clearer, drop the old mode parameter to the crtc dpms
function and rename it to intel_crtc_update_dpms.
- There's the curious case of intel_crtc->dpms_mode. With the previous
patches to remove the overlay pipe A code and to rework the load
detect pipe code, the big users are gone. We still keep it to avoid
enabling the pipe twice, but we duplicate this logic with
crtc->active, too. Still, leave this for now and just push a fake
dpms mode into it that reflects the state of the display pipe.
Changes in the encoder dpms functions:
- We clamp the dpms state to the supported range right away. This is
escpecially important for the VGA outputs, where only older hw
supports the intermediate states. This (and the crt->adpa_reg patch)
allows us to unify the crt dpms code again between all variants
(gmch, vlv and pch).
- We only enable/disable the output for dvo/sdvo and leave the encoder
running. The encoder will be disabled/enabled when we switch the
state of the entire output pipeline (which will happen right away
for non-cloned setups). This way the duplication is reduced and
strange interaction when disabling output ports at the wrong time
avoided.
The dpms code for all three types of connectors contains a bit of
duplicated logic, but I think keeping these special cases separate is
simpler: CRT is the only one that hanldes intermediate dpms state
(which requires extra logic to enable/disable things in the right
order), and introducing some abstraction just to share the code
between dvo and sdvo smells like overkill. We can do that once someone
bothers to implement cloning for the more modern outputs. But I doubt
that this will ever happen.
v2: s/crtc/crt/_set_dpms, noticed by Paulo Zanoni.

CRT is the first output which can be cloned, hence we cannot (yet)
move the dpms handling over to disable/enable. This requires some more
smarts in intel_crtc_dpms first to set the display pipe status
depening upon encoder->connectors_active of all connected encoders.
Because that will happen in a separate step, don't touch the dpms
functions, yet.
v2: Be careful about clearing the _DISABLE flags for intermediate dpms
modes - otherwise we might clobber the crt state when another (cloned)
connector gets enabled.
