Our PCH refclk init code currently assumes that the PCH SSC reference
can only be used for FDI. That is not true and it can be used by
SPLL/WRPLL for eDP SSC or clock bending as well. Before we go
reconfiguring it let's make sure no PLL is currently using the PCH
SSC reference.
For some reason the hw is not particularly upset about losing
the clock if we immediately follow up with a modeset. Can't
really explain why nothing times out during the crtc disable
at least, but that's what the logs say. With fastboot the
story is quite different and we lose the entire display if
we turn off the PCH SSC reference when it's still being used.
Since we totally skip configuring the PCH SSC reference it
may not be in the proper state for FDI. Hopefully that won't
be a problem in practice.
We really should move this code to be part of the modeset seqeuence
and properly deal with the potentially conflicting requirements
imposed on PLL reference clocks. But that requires actual work.
Let's toss in a TODO for that.

Prior to this commit we fail to init the DSI panel on the GPD MicroPC:
https://www.indiegogo.com/projects/gpd-micropc-6-inch-handheld-industry-laptop#/
The problem is intel_dsi_vbt_init() failing with the following error:
*ERROR* Burst mode freq is less than computed
The pclk in the VBT panel modeline is 70000, together with 24 bpp and
4 lines this results in a bitrate value of 70000 * 24 / 4 = 420000.
But the target_burst_mode_freq in the VBT is 418000.
This commit works around this problem by adding an intel_fuzzy_clock_check
when target_burst_mode_freq < bitrate and setting target_burst_mode_freq to
bitrate when that checks succeeds, fixing the panel not working.

Stop dumping plane->state for planes. That is the old state most of the
time and dumping stale information only serves to confuse people.
Instead dump the new state just for the planes included in the
operation. For now we'll include only the planes for the modeset/fastset
pipes in the dumps. But probably we want to dump them all eventually,
just not quite sure how to present that information nicely to the user.

ICL has so many planes that it can easily exceed the maximum
effective memory bandwidth of the system. We must therefore check
that we don't exceed that limit.
The algorithm is very magic number heavy and lacks sufficient
explanation for now. We also have no sane way to query the
memory clock and timings, so we must rely on a combination of
raw readout from the memory controller and hardcoded assumptions.
The memory controller values obviously change as the system
jumps between the different SAGV points, so we try to stabilize
it first by disabling SAGV for the duration of the readout.
The utilized bandwidth is tracked via a device wide atomic
private object. That is actually not robust because we can't
afford to enforce strict global ordering between the pipes.
Thus I think I'll need to change this to simply chop up the
available bandwidth between all the active pipes. Each pipe
can then do whatever it wants as long as it doesn't exceed
its budget. That scheme will also require that we assume that
any number of planes could be active at any time.

With gtt remapping in place we can use arbitrarily large
framebuffers. Let's bump the limits to 16kx16k on gen7+.
The limit was chosen to match the maximum 2D surface size
of the 3D engine.
With the remapping we could easily go higher than that for the
display engine. However the modesetting ddx will blindly assume
it can handle whatever is reported via kms. The oversized
buffer dimensions are not caught by glamor nor Mesa until
finally an assert will trip when genxml attempts to pack the
SURFACE_STATE. So we pick a safe limit to avoid the X server
from crashing (or potentially misbehaving if the genxml asserts
are compiled out).

The display engine stride limits are getting in our way. On SKL+
we are limited to 8k pixels, which is easily exceeded with three
4k displays. To overcome this limitation we can remap the pages
in the GTT to provide the display engine with a view of memory
with a smaller stride.
The code is mostly already there as We already play tricks with
the plane surface address and x/y offsets.
A few caveats apply:
* linear buffers need the fb stride to be page aligned, as
otherwise the remapped lines wouldn't start at the same
spot
* compressed buffers can't be remapped due to the new
ccs hash mode causing the virtual address of the pages
to affect the interpretation of the compressed data. IIRC
the old hash was limited to the low 12 bits so if we were
using that mode we could remap. As it stands we just refuse
to remapp with compressed fbs.
* no remapping gen2/3 as we'd need a fence for the remapped
vma, which we currently don't have. Need to deal with the
fence POT requirements, and do something about the gen2
gtt page size vs tile size difference

Reorder the code so that plane_state->view gets filled

stale values and could explode during remapping. The new
logic never remaps invisible planes since we don't have
a viewport, and instead pins the full fb instead
v6: Fix plane src coord checks after remapping by moving
plane_state->base.src to the final plane x/y offsets.
Allow intel_plane_check_stride() to fail even with
remapping (can happen at least with a linear 64bpp
fb with a 4k plane and a suitably inconvenient src
coordinates).

To overcome display engine stride limits we'll want to remap the
pages in the GTT. To that end we need a new gtt_view type which
is just like the "rotated" type except not rotated.
v2: Use intel_remapped_plane_info base type
s/unused/unused_mbz/ (Chris)
Separate BUILD_BUG_ON()s (Chris)
Use I915_GTT_PAGE_SIZE (Chris)
v3: Use i915_gem_object_get_dma_address() (Chris)
Trim the sg (Tvrtko)
v4: Actually trim this time. Limit the max length
to one row of pages to keep things simple

There isn't a separate power domain specific to PLLs. When programming
them we require the same power domain to be enabled which is needed when
accessing other display core parts (not specific to any
pipe/port/transcoder). This corresponds to the DISPLAY_CORE domain added
previously in this patchset, so use that instead to save bits in the
power domain mask.

Adjust the get transcoder timings for mipi dsi as per the
set timing calculations.
v2: Use the existing intel_get_pipe_timings and do the dsi
specific adjustments in the encoder get_config hook.(Ville, Jani)
v3: Exclude VBLANK and HBLANK registers for dsi transcoder.
v4: Fix the incomplete conditional logic.

On HSW the pipe A panel fitter lives inside the display power well,
and the input MUX for the EDP transcoder needs to be configured
appropriately to route the data through the power well as needed.
Changing the MUX setting is not allowed while the pipe is active,
so we need to force a full modeset whenever we need to change it.
Currently we may end up doing a fastset which won't change the
MUX settings, but it will drop the power well reference, and that
kills the pipe.

Convert the HSW pch_pfit.force_thru to a proper state variable
with readout and accompanying pipe conf check. Makes the logic
a bit more straightforward, and hopefully prevents some
breakage in the future.
'force_thru' is probably not the best name for this, but I
didn't manage to come up with anything better either, so I
left it alone.

hsw_enable_pc8()/hsw_disable_pc8() are more less equivalent to
the display core init/unit functions of later platforms. Relocate
the hsw/bdw code into intel_runtime_pm.c so that it sits next to
its cousins.

Turns out the cursor is compatible with the pipe "HDR mode". It's
only the actual SDR planes that get entirely bypassed during
blending. So let's ignore the cursor when checking if we have
any planes active that aren't HDR compatible. This fixes the
regressions in the kms_cursor_crc and kms_plane_cursor tests.

I fumbled the PIPEMISC write into the wrong place. It only gets
called for fastsets, but since value needs to be updated based on
the set of active planes it needs to be done for all plane updates.
Move it to the correct spot.
The symptoms include SDR planes never showing up if a previous
modeset/fastset left the pipe in HDR mode. This was immediately
obvious when running the kms_plane pixel format tests. Unfortunately
the test didn't realize it was scanning out pure black all the time
and declared success anyway.

It used to be handy that we only had a couple of headers, but over time
i915_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.
While at it, rename intel_i2c.c to intel_gmbus.c and the functions to
intel_gmbus_*.
No functional changes.
