It used to be handy that we only had a couple of headers, but over time
intel_drv.h has become unwieldy. Extract declarations to a separate
header file corresponding to the implementation module, clarifying the
modularity of the driver.
Ensure the new header is self-contained, and do so with minimal further
includes, using forward declarations as needed. Include the new header
only where needed, and sort the modified include directives while at it
and as needed.
No functional changes.

Starting from opregion version 2.1 (roughly corresponding to ICL+) the
RVDA field is relative from the beginning of opregion, not absolute
address.
Fix the error path while at it.
v2: Make relative vs. absolute conditional on the opregion version,
bumped for the purpose. Turned out there are machines relying on
absolute RVDA in the wild.
v3: Fix the version checks

If we reduce the suspend function for intel_opregion to do the minimum
required, the resume function can also do the simple task of notifier
the ACPI bios that we are back. This avoid some nasty restrictions on
the likes of register_acpi_notifier() that are not allowed during the
early phase of resume.
v2: Keep the order of acpi notify vs turning off ardy/drdy the same.

Currently the DDI encoder->type will change at runtime depending on
what kind of hotplugs we've processed. That's quite bad since we can't
really trust that that current value of encoder->type actually matches
the type of signal we're trying to drive through it.
Let's eliminate that problem by declaring that non-eDP DDI port will
always have the encoder type as INTEL_OUTPUT_DDI. This means the code
can no longer try to distinguish DP vs. HDMI based on encoder->type.
We'll leave eDP as INTEL_OUTPUT_EDP, since it'll never change and
there's a bunch of code that relies on that value to identify eDP
encoders.
We'll introduce a new encoder .compute_output_type() hook. This allows
us to compute the full output_types before any encoder .compute_config()
hooks get called, thus those hooks can rely on output_types being
correct, which is useful for cloning on oldr platforms. For now we'll
just look at the connector type and pick the correct mode based on that.
In the future the new hook could be used to implement dynamic switching
between LS and PCON modes for LSPCON.

v4: Rebase

Sometimes it would be most enlightening to debug systems by replacing
the VBT to be used. For example, in the referenced bug the BIOS provides
different VBT depending on the boot mode (UEFI vs. legacy). It would be
interesting to try the failing boot mode with the VBT from the working
boot, and see if that makes a difference.
Add a module parameter to load the VBT using the firmware loader, not
unlike the EDID firmware mechanism.
As a starting point for experimenting, one can pick up the BIOS provided
VBT from /sys/kernel/debug/dri/0/i915_opregion/i915_vbt.
v2: clarify firmware load return value check (Bob)
v3: kfree the loaded firmware blob

This reverts commit bb10d4ec3be4b069bfb61c60ca4f708f58f440f1.
Since commit c8ebfad7a063 ("drm/i915: Ignore OpRegion panel type except
on select machines") we ignore the OpRegion panel type except for
specific machines (handled via a DMI match), so having SKL explicitly
excluded from using the OpRegion panel type is redundant. So let's
remove the SKL check.

The graphics driver is supposed to define the DIDL, which are used for
_DOD, not the BIOS. Restore that behaviour.
This is basically a revert of
commit 3143751ff51a163b77f7efd389043e038f3e008e
Author: Zhang Rui <rui.zhang@intel.com>
Date: Mon Mar 29 15:12:16 2010 +0800
drm/i915: set DIDL using the ACPI video output device _ADR method return.
which went out of its way to cater to a specific BIOS, setting up DIDL
based on _ADR method. Perhaps that approach worked on that specific
machine, but on the machines I checked the _ADR method invents the
device identifiers out of thin air if DIDL has not been set. The source
for _ADR is also supposed to be the DIDL set by the driver, not the
other way around.
With this, we'll also limit the number of outputs to what the driver
actually has.
A side effect of this change is that the DIDL, and by proxy CADL, will
be initialized in the order of the connector list. That, in turn, has
internal panels in front, ensuring they're included in the DIDL and CADL
lists. Hopefully this ensures the BIOS does not block backlight hotkey
events, thinking the internal panel is off.

Turns out
commit a05628195a0d ("drm/i915: Get panel_type from OpRegion panel
details") has regressed quite a few machines. So it looks like we
can't use the panel type from OpRegion on all systems, and yet we
absolutely must use it on some specific systems.
Despite trying, I was unable to find any automagic way to determine
if the OpRegion panel type is respectable or not. The only glimmer
of hope I had was bit 8 in the SCIC response, but that turned out to
not work either (it was always 0 on both types of systems).
So, to fix the regressions without breaking the machine we know to need
the OpRegion panel type, let's just add a quirk for this. Only specific
machines known to require the OpRegion panel type will therefore use
it. Everyone else will fall bck to the VBT panel type.
The only known machine so far is a "Conrac GmbH IX45GM2". The PCI
subsystem ID on this machine is just a generic 8086:2a42, so of no use.
Instead we'll go with a DMI match.
I suspect we can now also revert
commit aeddda06c1a7 ("drm/i915: Ignore panel type from OpRegion on SKL")
but let's leave that to a separate patch.
v2: Do the DMI match in the opregion code directly, as dev_priv->quirks
gets populated too late

Dell XPS 13 9350 apparently doesn't like it when we use the panel type
from OpRegion. The OpRegion panel type (0) tells us to use use low
vswing for eDP, whereas the VBT panel type (2) tells us to use normal
vswing. The problem is that low vswing results in some display flickers.
Since no one seems to know how this stuff is supposed to be handled,
let's just ignore the OpRegion panel type on SKL for now.

Since drm_i915_private is now a subclass of drm_device we do not need to
chase the drm_i915_private->dev backpointer and can instead simply
access drm_i915_private->drm directly.

Current intel_opregion_init is called during the driver registration
phase and intel_opregion_fini from the unregistration phase. Rename the
functions so that this is clear from their names. The phases tell us
what we expect the existing hw state to be, e.g. whether interrupts are
still enabled etc.
It should be noted that the opregion init/fini routines are asymmetric
and this is carried across into their new names. Indeed, their new names
make it even clearer that perhaps all is not well in the opregion
suspend/resume sequence (as well in the module unload).

I have noticed some of our interrupt handlers use both dev and
dev_priv while they could get away with only dev_priv in the
huge majority of cases.
Tidying that up had a cascading effect on changing functions
prototypes, so relatively big churn factor, but I think it is
for the better.
For example even where changes cascade out of i915_irq.c, for
functions prefixed with intel_, genX_ or <plat>_, it makes more
sense to take dev_priv directly anyway.
This allows us to eliminate local variables and intermixed usage
of dev and dev_priv where only one is good enough.
End result is shrinkage of both source and the resulting binary.
i915.ko:
- .text 000b0899
+ .text 000b0619
Or if we look at the Gen8 display irq chain:
-00000000000006ad t gen8_irq_handler
+0000000000000663 t gen8_irq_handler
-0000000000000028 T intel_opregion_asle_intr

-000000000000008c t ilk_hpd_irq_handler

-000000000000022e t cpt_irq_handler

So small shrinkage but it is all fast paths so doesn't harm.

We've had problems on several occasions with using the panel type
from the VBT block 40. Usually it seems to be 2, which often
doesn't give us the correct timings for the panel. After some
more digging I found a way to get a panel type via the OpRegion
SWSCI GBDA "Get Panel Details" method. Let's try to use it.
The spec has this to say about the output:
"Bits [15:8] - Panel Type
Bits contain the panel type user setting from CMOS
00h = Not Valid, use default Panel Type & Timings from VBT
01h - 0Fh = Panel Number"
Another version of the spec lists the valid range as 1-16, which makes
more sense since VBT supports 16 panels. Based on actual results
from Rob's G45, 1-16 is what we need to accept.
The other bits in the output don't look relevant for the problem at
hand.
The input is specified as:
"Bits [31:4] - Reserved
Reserved (must be zero)
Bits [3:0] - Panel Number
These bits contain the sequential index of Panel, starting at 0 and
counting upwards from the first integrated Internal Flat-Panel Display
Encoder present, and then from the first external Display Encoder
(e.g., S/DVO-B then S/DVO-C) which supports Internal Flat-Panels.
0h - 0Fh = Panel number"
For now I've just hardcoded the input panel number as 0. That would seem
like a decent choise for LVDS. Not so sure about eDP when port != A.
v2: Accept values 1-16
Filter out bogus results in opregion code (Jani)
Add debug logging for all the different branches (Jani)

SKL and BXT qualifies the HAS_DDI() check, and hence haswell
modeset functions are re-used for modeset sequence. But DDI
interface doesn't include support for DSI.
This patch adds:
1. cases for DSI encoder, in those modeset functions and allows
a CRTC modeset
2. Adds call to pre_pll enabled from CRTC modeset function. Nothing
needs to be done as such in CRTC for DSI encoder, as PLL, clock
and and transcoder programming will be taken care in encoder's
pre_enable and pre_pll_enable function.
v2: Fixed Jani's review comments. Added INVALID_PORT for non DDI
encoder like DSI for platforms having HAS_DDI as true.
v3: Rebased on latest drm-nightly branch. Added a WARN_ON for invalid
encoder.
v4: WARN_ON for invalid encoder is refactored as per Jani's suggestion.
Fixed the sequence for pre_pll_enable.
v5: Protected DDI code paths in case of DSI encoder calls.
