The mapping from enum port to whatever port numbering scheme is used by
the SWSCI Display Power State Notification is odd, and the memory of it
has faded. In any case, the parameter only has space for ports numbered
[0..4], and UBSAN reports bit shift beyond it when the platform has port
F or more.
Since the SWSCI functionality is supposed to be obsolete for new
platforms (i.e. ones that might have port F or more), just bail out
early if the mapped and mangled port number is beyond what the Display
Power State Notification can support.

Apparently I totally fumbled the loop condition when I
removed the ARRAY_SIZE() stuff from the dbuf slice config
lookup. Comparing the loop index with the active_pipes bitmask
is utter nonsense, what we want to do is check to see if the
mask is zero or not.
Note that the code actually ended up working correctly despite
the fumble, up until commit eef173954432 ("drm/i915: Allow

Currently the bigjoiner state copy logic is kind of
a byzantine mess.
Clean it up to operate in the following manner during a full
modeset:
1) master uapi -> hw state copy
2) master hw -> slave hw state copy
And during a non-modeset update we do:
1) master uapi -> hw state light copy
2) master hw -> slave hw state light copy
I think that is now easier to reason about since we never do
any kind of master uapi -> slave hw state copy short circuit
that could happen previously.
Obviously this does now depend on the master uapi->hw copy
always happening before the master hw -> slave hw copy, but
that is guaranteed by the fact that we always add both crtcs
to the state early, the crtcs are registered in pipe
order (so the compute_config loop happens in pipe order),
and the hardware requires the master pipe has to be lower
than the slave pipe as well. And for good measure we shall
add a check+WARN for this before doing the bigjoiner crtc
assignment.

There's some weird junk in intel_atomic_check_bigjoiner()
that's trying to look at the old crtc state's bigjoiner
usage for some reason. That code is totally unnecessary,
and maybe even actively harmful. Not entirely sure which
since it's such a mess that I can't actually wrap my brain
around what it ends up doing.
Either way, thanks to intel_bigjoiner_add_affected_crtcs()
all of the old bigjoiner crtcs are guaranteed to be in the
state already if any one of them is in the state. Also if
any one of those crtcs got flagged for a modeset, then all
of them will have been flagged, and the bigjoiner links
will have been detached via kill_bigjoiner_slave().
So there is no need to look examing any old bigjoiner
usage in intel_atomic_check_bigjoiner(). All we have to care
about is whether bigjoiner is needed for the new state,
and whether we can get the slave crtc we need.

We seem to be missing a few things from the bigjoiner state copy.
Namely hw.mode isn't getting copied (which probably causes PIPESRC
to be misconfigured), CTM/LUTs aren't getting copied (which could
cause the pipe to produced incorrect output), and we also forgot
to copy over the color_mgmt_changed flag so potentially we fail
to do the actual CTM/LUT programming (assuming we aren't doing
a full modeset or fastset). Fix it all.

The core doesn't flag scaling_filter prop changes as needing
a modeset. That doesn't work for us since we only reprogram the
pipe scaler during full modesets and fastsets. So we need to
flag the prop change as a modeset ourselves. Assuming nothing else
has changed the operation will get promoted (demoted?) to a fastset
later.

On i915_selftest@live@gt_timelines, we create many contexts in loop and
create and submit request and then destoy contexts. Destroying the context
needs to disable scheduling, wait for G2H, deregister context and wait
for G2H to destroy each context. Idling of the gt has to wait for all
this to complete which is taking ~3sec for this test.
Hence we are increasing the igt_flush_test's timeout for gt idling to

Commit d6c6a76f80a1 ("drm: Update MST First Link Slot Information Based

accordingly, and commit 41724ea273cd ("drm/amd/display: Add DP 2.0 MST

This feels more than a little cumbersome, especially updating the

.compute_config hook rather than iterating over all MST managers and
connectors in global mode config .atomic_check. Fingers crossed.

The DP 2.0 errata completely overhauls the 128b/132b link training, with
no provisions for backward compatibility with the original DP 2.0
specification.
The changes are too intrusive to consider reusing the same code for both
8b/10b and 128b/132b, mainly because the LTTPR channel equalisation is
done concurrently instead of serialized.
NOTES:
* It's a bit unclear when to wait for DP_INTERLANE_ALIGN_DONE and
per-lane DP_LANE_SYMBOL_LOCKED. Figure xx4 in the SCR implies the
LANEx_CHANNEL_EQ_DONE sequence may end with either 0x77,0x77,0x85 *or*
0x33,0x33,0x84 (for four lane configuration in DPCD 0x202..0x204)
i.e. without the above bits set. Text elsewhere seems contradictory or
incomplete.
* We read entire link status (6 bytes) everywhere instead of individual
DPCD addresses.
* There are some subtle ambiguities or contradictions in the order of
some DPCD access and TPS signal enables/disables. It's also not clear
whether these are significant.

- Wait for intra-hop clear after link training end (Ville)
- Wait instead of single check for intra-hop clear before link train

no harm in making the code totally consistent.
