d2e3fce9dd drm/i915: Handle max_bpc==16
EDID can declare the maximum supported bpc up to 16,
and apparently there are displays that do so. Currently
we assume 12 bpc is tha max. Fix the assumption and
toss in a MISSING_CASE() for any other value we don't
expect to see.

This fixes modesets with a display with EDID max bpc > 12.
Previously any modeset would just silently fail on platforms
that didn't otherwise limit this via the max_bpc property.
In particular we don't add the max_bpc property to HDMI
ports on gmch platforms, and thus we would see the raw
max_bpc coming from the EDID.

I suppose we could already adjust this to also allow 16bpc,
but seeing as no current platform supports that there is
little point.

d9a57c8539 drm/i915: Fix encoder lookup during PSR atomic check
The atomic check hooks must look up the encoder to be used with a
connector from the connector's atomic state, and not assume that it's
the connector's current attached encoder. The latter one can change
under the atomic check func, or can be unset yet as in the case of MST
connectors.

This fixes

1664ffee76 drm/i915: Mark ininitial fb obj as WT on eLLC machines to avoid rcu lockup during fbdev init
Currently we leave the cache_level of the initial fb obj
set to NONE. This means on eLLC machines the first pin_to_display()
will try to switch it to WT which requires a vma unbind+bind.
If that happens during the fbdev initialization rcu does not
seem operational which causes the unbind to get stuck. To
most appearances this looks like a dead machine on boot.

Avoid the unbind by already marking the object cache_level
as WT when creating it. We still do an excplicit ggtt pin
which will rewrite the PTEs anyway, so they will match whatever
cache level we set.

354842df38 drm/i915/dp: Tweak initial dpcd backlight.enabled value
In commit 7994672309 ("drm/i915: Assume 100% brightness when not in
DPCD control mode"), we fixed the brightness level when DPCD control was
not active to max brightness. This is as good as we can guess since most
backlights go on full when uncontrolled.

However in doing so we changed the semantics of the initial
'backlight.enabled' value. At least on Pixelbooks, they  were relying
on the brightness level in DP_EDP_BACKLIGHT_BRIGHTNESS_MSB to be 0 on
boot such that enabled would be false. This causes the device to be
enabled when the brightness is set. Without this, brightness control
doesn't work. So by changing brightness to max, we also flipped enabled
to be true on boot.

To fix this, make enabled a function of brightness and backlight control
mechanism.

214bba5061 drm/i915: Set all unused color plane offsets to ~0xfff again
When the number of potential color planes grew to 4 we stopped
setting all unused color plane offsets to ~0xfff. The code
still tries to do this, but actually does nothing since the
loop limits are bogus.

skl_check_main_surface() actually depends on this ~0xfff
behaviour as it will make sure to move the main surface
offset below the aux surface offset because the hardware
AUX_DIST must be a non-negative value [1], and for simplicity
it doesn't bother checking if the AUX plane is actually
needed or not. So currently it may end up shuffling the
main surface around based on some stale leftover AUX offset.

The skl+ plane code also just blindly calculates the AUX_DIST
whether or not the AUX plane is actually needed by the hw or
not, and that too will now potentially use some stale AUX
surface offset in the calculation. Would seem nicer to
guarantee a consistent non-negative AUX_DIST always.

So bring back the original ~0xfff offset behaviour for
unused color planes. Though it doesn't seem super likely
that this inconsistency would cause any real issues.

f0b707c125 drm/i915: Fix TGL DKL PHY DP vswing handling
The HDMI vs. not-HDMI check got inverted whem the bogus encoder->type
checks were eliminated. So now we're using 0 as the link rate on DP
and potentially non-zero on HDMI, which is exactly the opposite of
what we want. The original bogus check actually worked more correctly
by accident since if would always evaluate to true. Due to this we
now always use the RBR/HBR1 vswing table and never ever the HBR2+
vswing table. That is probably not a good way to get a high quality
signal at HBR2+ rates. Fix the check so we pick the right table.

ef80c1a1d2 drm/i915: Fix state checker hw.active/hw.enable readout
Previously intel_dump_pipe_config() used to dump the full crtc state
whether or not the crtc was logically enabled or not. As that meant
occasionally dumping confusing stale garbage I changed it to
check whether the crtc is logically enabled or not. However I did
not realize that the state checker readout code does not
populate crtc_state.hw.{active,enabled}. Hence the state checker
dump would only give us a full dump of the sw state but not the hw
state. Fix that by populating those bits of the hw state as well.

For platforms that can't do native 4:2:0 outout we may still be
able to do it by getting the DP->HDMI protocol converter to

have to configure our hardware to output YCbCr 4:4:4, which we've

Having a mode where the display hardware is present but we try

to reason what the fallout might be from skipping some random
bits of programming.

Let's just neuter INTEL_DISPLAY_ENABLED so that we treat the
hardware as fully present, except we just don't register any
outputs. That's still rather sketchy if the outputs are already
enabled when the driver is loaded. I think the simplest solution
would be to probe everything as normal and just return
disconnected" from all .detect() hooks. That would avoid anything
automagically enabling those outputs, but the driver could then
shut things down using the normal codepaths.

23d3e3799f drm/i915: Fix g4x+ sprite dotclock limit for upscaling
Even if we're not doing downscaling we should account for
some of the extra dotclock limitations for g4x+ sprites. In
particular we must never exceed the 90% rule, and with RGB
that limits actually drops to 80%.

So instead of bailing out when upscaling let's clamp the
scaling factor appropriately and go through the rest of
calculation normally. By luck we already did the full
calculations for the 1:1 case.

0560c2173e drm/i915: Nuke dpio_phy_iosf_port[]
There's no real reason to stash away the DPIO PHY IOSF sideband port
numbers for VLV/CHV. Just compute them at runtime in the sideband code.

Gets rid of the oddball intel_init_dpio() function from the high level
init flow.

0c4c801b31 drm/i915: fix regression leading to display audio probe failure on GLK
In commit 4f0b4352bd ("drm/i915: Extract cdclk requirements checking
to separate function") the order of force_min_cdclk_changed check and
intel_modeset_checks(), was reversed. This broke the mechanism to
immediately force a new CDCLK minimum, and lead to driver probe
errors for display audio on GLK platform with 5.9-rc1 kernel. Fix
the issue by moving intel_modeset_checks() call later.

[vsyrjala: It also broke the ability of planes to bump up the cdclk
and thus could lead to underruns when eg. flipping from 32bpp to
64bpp framebuffer. To be clear, we still compute the new cdclk
correctly but fail to actually program it to the hardware due to
intel_set_cdclk_{pre,post}_plane_update() not getting called on
account of state->modeset==false.]

47b086934f drm/i915: Make sure execbuffer always passes ww state to i915_vma_pin.
As a preparation step for full object locking and wait/wound handling
during pin and object mapping, ensure that we always pass the ww context
in i915_gem_execbuffer.c to i915_vma_pin, use lockdep to ensure this
happens.

This also requires changing the order of eb_parse slightly, to ensure
we pass ww at a point where we could still handle -EDEADLK safely.
