Pull drm updates from Dave Airlie:
"Okay this is the big one, I was stalled on the fbdev pull req as I
stupidly let fbdev guys merge a patch I required to fix a warning with
some patches I had, they ended up merging the patch from the wrong
place, but the warning should be fixed. In future I'll just take the
patch myself!
Outside drm:
There are some snd changes for the HDMI audio interactions on haswell,
they've been acked for inclusion via my tree. This relies on the
wound/wait tree from Ingo which is already merged.
Major changes:
AMD finally released the dynamic power management code for all their
GPUs from r600->present day, this is great, off by default for now but
also a huge amount of code, in fact it is most of this pull request.
Since it landed there has been a lot of community testing and Alex has
sent a lot of fixes for any bugs found so far. I suspect radeon might
now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable
dynamic powermanagement for anyone.
New drivers:
Renesas r-car display unit.
Other highlights:
- core: GEM CMA prime support, use new w/w mutexs for TTM
reservations, cursor hotspot, doc updates
- dvo chips: chrontel 7010B support
- i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
support (this time for sure)
- nouveau: async buffer object deletion, context/register init
updates, kernel vp2 engine support, GF117 support, GK110 accel
support (with external nvidia ucode), context cleanups.
- exynos: memory leak fixes, Add S3C64XX SoC series support, device
tree updates, common clock framework support,
- qxl: cursor hotspot support, multi-monitor support, suspend/resume
support
- mgag200: hw cursor support, g200 mode limiting
- shmobile: prime support
- tegra: fixes mostly
I've been banging on this quite a lot due to the size of it, and it
seems to okay on everything I've tested it on."

Last 3.11 feature pull. I have a few odds bits and pieces and fixes in my
queue, I'll sort them out later on to see what's for 3.11-fixes and what's
for 3.12. But nothing to hold this here up imo.
Highlights:
- more hangcheck work from Mika and Chris to prepare for arb robustness
- trickle feed fixes from Ville
- first parts of the shared pch pll rework, with some basic hw state
readout and cross-checking (this shuts up the confused pch pll refcount
WARN that Linus just recently forwarded)
- Haswell audio power well support from Wang Xingchao (alsa bits acked by
Takashi)
- some cleanups and asserts sprinkling around the plane/gamma enabling
sequence from Ville
- more gtt refactoring from Ben
- clear up the adjusted->mode vs. pixel clock vs. port clock confusion
- 30bpp support, this time for real hopefully

Nowadays (i.e. with Valleyview) we also have edp on non-PCH_SPLIT
platforms, so just checking for LVDS is not good enough.
Secondly we have full pfit pipe config tracking, so we'll correctly
disable the pfit as part of the initial modeset.
For fastboot we need a bit of work here to correctly kill unsupported
configs (if e.g. the pfit is used on anything else than the built-in
panel). But since that's not yet supported we don't need to worry.

Only lvds/tv did actually check for cloning or not, but many more
places should.
Notices because my ivb tried to enable both cpu edp and vga on the
first crtc - the resulting confusion between has_pch_encoder,
has_dp_encoder but not actually being a pch dp encoder resulting in
hilarity (hitting a BUG).
We _really_ need an igt to random-walk our modeset space more
exhaustively.
The bug seems to have been exposed due to a race in the hw load
detection support for VGA: Right after a hotplug VGA was still
detected as connected, but obviously reading the EDID wasn't possible
any more. Hence why restarting X a bit later fixed things. Due to the
1024x756 fallback resolution suddenly more outputs had the same
resolution.
On top of that SNA was confused with the possible_clones mask, trying
to clone outputs which cannot be cloned. That bug is now fixed with

Pfit state readout is a bit ugly on gen2/3 due to the intermingling
with the lvds state, but alas.
Also note that since state is always cleared to zero we can
unconditonally compare all the state and completely neglect the actual
platform we're running on.
v2: Properly check for the pfit power domain on haswell.
v3: Don't check pgm_ratios on gen4+, they're auto-computed by the hw.
v4: Properly clear the lvds border bits, upset the state checker a

Writing hw registers from compute_config?
Just say no!
In this case not too horrible since we write a constant 0, and only
debugging would put something else in there. But while checking that
code I've noticed that this register disappeared on pch platforms, so
fix that up, too.
And adjust the comment a bit, it's outdated.

pipe_config is the new dev_priv!
More seriously, this is actually better since a pipe_config can be
thrown away if the modeset compute config stage fails. Whereas any
state stored in dev_prive needs to be painstakingly restored, since
otherwise a dpms off/on will wreak massive havoc. Yes, that even
applies to state only used in ->mode_set callbacks, since we need to
call those even for dpms on when the Haswell power well cleared
everything out.

So on a bunch of setups we only have 2 fdi lanes available, e.g. hsw
VGA or 3 pipes on ivb. And seemingly a lot of modes don't quite fit
into this, among them the default 1080p mode.
The solution is to dither down the pipe a bit so that everything fits,
which this patch implements.
But ports compute their state under the assumption that the bpp they
pick will be the one selected, e.g. the display port bw computations
won't work otherwise. Now we could adjust our code to again up-dither
to the computed DP link parameters, but that's pointless.
So instead when the pipe needs to adjust parameters we need to retry
the pipe_config computation at the encoder stage. Furthermore we need
to inform encoders that they should not increase bandwidth
requirements if possible. This is required for the hdmi code, which
prefers the pipe to up-dither to either of the two possible hdmi bpc
values.
LVDS has a similar requirement, although that's probably only
theoretical in nature: It's unlikely that we'll ever see an 8bpc
high-res lvds panel (which is required to hit the 2 fdi lane limit).
eDP is the only thing which could increase the pipe_bpp setting again,
even when in the retry-loop. This could hit the WARN. Two reasons for
not bothering:
- On many eDP panels we'll get a black screen if the bpp settings
don't match vbt. So failing the modeset is the right thing to do.
But since that also means it's the only way to light up the panel,
it should work. So we shouldn't be able to hit this WARN.
- There are still opens around the eDP panel handling, and maybe we
need additional tricks. Before that happens it's imo no use trying
to be too clever.
Worst case we just need to kill that WARN or maybe fail the compute
config stage if the eDP connector can't get the bpp setting it wants.
And since this can only happen with an fdi link in between and so for
pch eDP panels it's rather unlikely to blow up, if ever.
v2: Rebased on top of a bikeshed from Paulo.
v3: Improve commit message around eDP handling with the stuff
things with Imre.

This gets the panel fitter working on eDP on VLV, and should also apply
to eDP panels on G4x chipsets (if we ever detect and mark an all-in-one
panel as eDP anyway).
A few cleanups are still possible on top of this, for example the LVDS
border control could be placed in the LVDS encoder structure and updated
based on the result of the panel fitter calculation.
Multi-pipe fitting isn't handled correctly either if we ever get a config
that wants to try the panel fitter on more than one output at a time.

Up to now we've relied on the bios to get this right for us. Let's try
out whether our code has improved a bit, since we should dither
always when the output bpp doesn't match the plane bpp.
- gen5+ should be fine, since we only use the bios hint as an upgrade.
- gen4 changes, since here dithering is still controlled in the lvds
register.
- gen2/3 has implicit dithering depeding upon whether you use 2 or 3
lvds pairs (which makes sense, since it only supports 8bpc pipe
outpu configurations).
- hsw doesn't support lvds.
v2: Remove redudant dither setting.
v3: Completly drop reliance on dev_priv->lvds_dither.
v4: Enable dithering on gen2/3 only when we have a 18bpp panel, since
up-dithering to a 24bpp panel is not supported by the hw. Spotted by
Ville.
v5: Also only enable lvds port dithering on gen4 for 18bpp modes. In
practice this only excludes dithering a 10bpc plane down for a 24bpp
lvds panel. Not something we truly care about. Again noticed by Ville.
v6: Actually git add.

is obeyed with a neat assert.
Also check whether the pfit is off before enabling it - if not we've

Backlight cleanup in the eDP connector destroy callback caused the
backlight device to be removed on some systems that first initialized LVDS
and then attempted to initialize eDP. Prevent multiple backlight
initializations, and ensure backlight cleanup is only done once by moving
it to modeset cleanup.
A small wrinkle is the introduced asymmetry in backlight
setup/cleanup. This could be solved by adding refcounting, but it seems
overkill considering that there should only ever be one backlight device.

The procedure has now 3 steps:
1. Compute the bpp that the plane will output, this is done in
pipe_config_set_bpp and stored into pipe_config->pipe_bpp. Also,
this function clamps the pipe_bpp to whatever limit the EDID of any
connected output specifies.
2. Adjust the pipe_bpp in the encoder and crtc functions, according to
whatever constraints there are.
3. Decide whether to use dither by comparing the stored plane bpp with
computed pipe_bpp.
There are a few slight functional changes in this patch:
- LVDS connector are now also going through the EDID clamping. But in
a 2nd change we now unconditionally force the lvds bpc value - this
shouldn't matter in reality when the panel setup is consistent, but
better safe than sorry.
- HDMI now forces the pipe_bpp to the selected value - I think that's
what we actually want, since otherwise at least the pixelclock
computations are wrong (I'm not sure whether the port would accept
e.g. 10 bpc when in 12bpc mode). Contrary to the old code, we pick
the next higher bpc value, since otherwise there's no way to make
use of the 12 bpc mode (since the next patch will remove the 12bpc
plane format, it doesn't exist).
Both of these changes are due to the removal of the
pipe_bpp = min(display_bpp, plane_bpp);
statement.
Another slight change is the reworking of the dp bpc code:
- For the mode_valid callback it's sufficient to only check whether
the mode would fit at the lowest bpc.
- The bandwidth computation code is a bit restructured: It now walks
all available bpp values in an outer loop and the codeblock that
computes derived values (once a good configuration is found) has been
moved out of the for loop maze. This is prep work to allow us to
successively fall back on bpc values, and also correctly support bpc
values != 8 or 6.
v2: Rebased on top of Paulo Zanoni's little refactoring to use more
drm dp helper functions.
v3: Rebased on top of Jani's eDP bpp fix and Ville's limited color
range work.
v4: Remove the INTEL_MODE_DP_FORCE_6BPC #define, no longer needed.
v5: Remove intel_crtc->bpp, too, and fix up the 12bpc check in the
hdmi code. Also fixup the bpp check in intel_dp.c, it'll get reworked
in a later patch though again.
v6: Fix spelling in a comment.
v7: Debug output improvements for the bpp computation.
v8: Fixup 6bpc lvds check - dual-link and 8bpc mode are different
things!
v9: Reinstate the fix to properly ignore the firmware edp bpp ... this
was lost in a rebase.
v10: Both g4x and vlv lack 12bpc pipes, so don't enforce that we have
that. Still unsure whether this is the way to go, but at least 6bpc
for a 8bpc hdmi output seems to work.
v11: And g4x/vlv also lack 12bpc hdmi support, so only support high
depth on DP. Adjust the code.
v12: Rebased.
v13: Split out the introduction of pipe_config->dither|pipe_bpp, as

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.

Only used by the lvds encoder. Note that we shouldn't do the same
simple conversion with the FORCE_6BPC flag, since that's much better
handled by moving all the pipe_bpc computation around.
This requires that we pass the pipe config around to encoders, so
that they can set special attributes and set constraints. To do so
introduce a new ->compute_config encoder callback, which is called in
stead of the drm crtc helper's ->mode_fixup.
To avoid massive churn all over the codebase we don't want to convert
all existing ->mode_fixup functions. Instead I've opted to convert
them on an as-needed basis (mostly to cut down on rebase conflicts and
to have more freedom to experiment around while developing the
patches).

- 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.

- Write backlight regs even harder ... another installement in our eternal

- Fixup lid notifier vs. suspend/resume races (Zhang Rui). Prep work for

With the previous patch "drm/i915: disable shared panel fitter for
pipe" we now disable the panel fitter at the right spot in the modeset
sequence in the crtc functions on all platforms. Hence the disabling
in intel_disable_lvds is no longer required and potentially harmful
(since the plane is still enabled at this point).
Similarly on the enabling side we enable the panel fitter in the lvds
callback only once the plane is enabled. Which is too late. Hence move
this into a new intel_pre_enable_lvds callback.
Finally we can ditch lvds_encoder->pfit_dirty - this was required to
work around the crtc helper semantics, but with the new i915 modeset
infrastructure we should enable/disable the pfit only when enabling or
disabling the entire output pipeline. So separate state tracking for
the pfit is no longer required.

enable/disable the pfit on i9xx platforms at the right point of time
compared to the old code.]

i915 driver needs to do modeset when
1. system resumes from sleep
2. lid is opened
In PM_SUSPEND_MEM state, all the GPEs are cleared when system resumes,
thus it is the i915_resume code does the modeset rather than intel_lid_notify().
But in PM_SUSPEND_FREEZE state, this will be broken because
system is still responsive to the lid events.
1. When we close the lid in Freeze state, intel_lid_notify() sets modeset_on_lid.
2. When we reopen the lid, intel_lid_notify() will do a modeset,
before the system is resumed.

three different modeset flags are introduced in this patch
MODESET_ON_LID_OPEN: do modeset on next lid open event
MODESET_DONE: modeset already done
MODESET_SUSPENDED: suspended, only do modeset when system is resumed
In this way,
1. when lid is closed, MODESET_ON_LID_OPEN is set so that
we'll do modeset on next lid open event.
2. when lid is opened, MODESET_DONE is set
so that duplicate lid open events will be ignored.
3. when system suspends, MODESET_SUSPENDED is set.
In this case, we will not do modeset on any lid events.
Plus, locking mechanism is also introduced to avoid racing.

The aim of this locking rework is that ioctls which a compositor should be
might call for every frame (set_cursor, page_flip, addfb, rmfb and
getfb/create_handle) should not be able to block on kms background
activities like output detection. And since each EDID read takes about
25ms (in the best case), that always means we'll drop at least one frame.
The solution is to add per-crtc locking for these ioctls, and restrict
background activities to only use the global lock. Change-the-world type
of events (modeset, dpms, ...) need to grab all locks.
Two tricky parts arose in the conversion:
- A lot of current code assumes that a kms fb object can't disappear while
holding the global lock, since the current code serializes fb
destruction with it. Hence proper lifetime management using the already
created refcounting for fbs need to be instantiated for all ioctls and
interfaces/users.
- The rmfb ioctl removes the to-be-deleted fb from all active users. But
unconditionally taking the global kms lock to do so introduces an
unacceptable potential stall point. And obviously changing the userspace
abi isn't on the table, either. Hence this conversion opportunistically
checks whether the rmfb ioctl holds the very last reference, which
guarantees that the fb isn't in active use on any crtc or plane (thanks
to the conversion to the new lifetime rules using proper refcounting).
Only if this is not the case will the code go through the slowpath and
grab all modeset locks. Sane compositors will never hit this path and so
avoid the stall, but userspace relying on these semantics will also not
break.
All these cases are exercised by the newly added subtests for the i-g-t
kms_flip, tested on a machine where a full detect cycle takes around 100
ms. It works, and no frames are dropped any more with these patches
applied. kms_flip also contains a special case to exercise the
above-describe rmfb slowpath.

Two exceptions:
- debugfs files only read information which is not related to crtc, so
can stay on the modeset_config lock.
- Same holds for the edp vdd work in intel_dp.c. Add a corresponding
WARN_ON and a comment next to the intel_dp struct fields for

As there is 1:1 mapping between encoder and connector for the LVDS, the
goal is to simply reduce the amount of noise within the connector
functions, i.e. we split the encoder/connector for LVDS as best we can and
try to only operate on the LVDS connector from the connector funcs and the
LVDS encoder form the encoder funcs.
