Thierry needs fd70c7755bf0 ("drm/bridge: tc358767: fix max_tu_symbol

Some adjacent changes conflicts, plus some clashes in i915 due to
cherry-picking and git trying to be helpful and leaving both versions

As per the display enable sequence, we need to follow the enable sequence
for slaves first with DP_TP_CTL set to Idle and configure the transcoder
port sync register to select the corersponding master, then follow the
enable sequence for master leaving DP_TP_CTL to idle.
At this point the transcoder port sync mode is configured and enabled
and the Vblanks of both ports are synchronized so then set DP_TP_CTL
for the slave and master to Normal and do post crtc enable updates.

separate ports
In case of tiled displays where different tiles are displayed across
different ports, we need to synchronize the transcoders involved.
This patch implements the transcoder port sync feature for
synchronizing one master transcoder with one or more slave

and the master transcoder is unaware that it is operating
in this mode.
This has been tested with tiled display connected to ICL.

Transcoder Port Sync
In case of tiled displays when the two tiles are sent across two CRTCs
over two separate DP SST connectors, we need a mechanism to synchronize
the two CRTCs and their corresponding transcoders.
So use the master-slave mode where there is one master corresponding
to last horizontal and vertical tile that needs to be genlocked with
all other slave tiles.
This patch identifies saves the master transcoder in all the slave
CRTC states. This is needed to select the master CRTC/transcoder
while configuring transcoder port sync for the corresponding slaves.

Commit 2d6f6f359fd8 ("drm/i915: add i915_driver_modeset_remove()")
claimed removal of asymmetry in probe() and remove() calls, however, it
didn't take care of calling intel_irq_uninstall() on driver remove.
That doesn't hurt as long as we still call it from
intel_modeset_driver_remove() but in order to have full symmetry we
should call it again from i915_driver_modeset_remove().
Note that it's safe to call intel_irq_uninstall() twice thanks to
commit b318b82455bd ("drm/i915: Nuke drm_driver irq vfuncs"). We may
only want to mention the case we are adding in a related FIXME comment
provided by that commit. While being at it, update the name of
function mentioned as calling it out of sequence as that name has been
changed meanwhile by commit 78dae1ac35dd ("drm/i915: Propagate
"_remove" function name suffix down").

All the timeout values fit in u16, so let's shrink the structure

This ends up actually increasing the .text size a bit due to
some changes in instructions (constant imul+small jmps replaced
with mov+bigger jmpqs). Seems pretty arbitrary to me so I'll
just pretend I didn't see it.

The only reason for the timeout2 value in the array is the
HDCP_2_2_AKE_SEND_HPRIME message. But that one still needs
special casing inside the loop, and so just ends up making
the code harder to read. Let's just remove this leaky
timeout2 abstraction and special case that one command
in a way that is easy to understand. We can then remove the
timeout2 member from struct entirely.

The 'realloc_pipes' bitmask is pointless. It is either:
a) the set of pipes which are already part of the state,
in which case adding them again is entirely redundant
b) the set of all pipes which we then add to the state
Also the fact that 'realloc_pipes' uses the crtc indexes is
going to bite is at some point so best get rid of it quick.

Normally, we try and skip submission if ELSP[1] is filled. However, we
may desire to enable timeslicing due to the queue priority, even if
ELSP[1] itself does not require timeslicing. That is the queue is equal
priority to ELSP[0] and higher priority then ELSP[1]. Previously, we
would wait until the context switch to preempt the current ELSP[1], but
with timeslicing, we want to preempt ELSP[0] and replace it with the
queue.
In writing the test case, it become quickly apparent that we were also
suppressing the tasklet during promotion and so failing to notice when
the queue started requiring timeslicing.

Where the function, or code segment, operates on intel_gt, we need to
start passing it instead of i915 to for_each_engine(_masked).
This is another partial step in migration of i915->engines[] to
gt->engines[].

Medium term goal is to eliminate the i915->engine[] array and to get there
we have recently introduced equivalent array in intel_gt. Now we need to
migrate the code further towards this state.
This next step is to eliminate usage of i915->engines[] from the
for_each_engine_masked iterator.
For this to work we also need to use engine->id as index when populating
the gt->engine[] array and adjust the default engine set indexing to use
engine->legacy_idx instead of assuming gt->engines[] indexing.
v2:
* Populate gt->engine[] earlier.
* Check that we don't duplicate engine->legacy_idx
v3:
* Work around the initialization order issue between default_engines()
and intel_engines_driver_register() which sets engine->legacy_idx for
now. It will be fixed properly later.
v4:
* Merge with forgotten v2.5.

The locks (active.lock and rq->lock) need to be taken with disabled
interrupts. This is done in i915_request_retire() by disabling the
interrupts independently of the locks itself.
While local_irq_disable()+spin_lock() equals spin_lock_irq() on vanilla
it does not on PREEMPT_RT.
Chris Wilson confirmed that local_irq_disable() was just introduced as
an optimisation to avoid enabling/disabling interrupts during
lock/unlock combo.
Enable/disable interrupts as part of the locking instruction.

The request selftests straddle the boundary between checking the driver
and the hardware. They are subject to the quirks of the underlying HW,
but operate on top of the backend abstractions. The tests focus on the
scheduler elements and so should check for interactions of the scheduler
across all exposed engines.

responsible of. While at it, fix the documentation for the auth

The MSA MISC computation now depends on the connector state, and
we do it from the DDI .pre_enable() hook. All that is fine for
DP SST but with MST we don't actually pass the connector state
to the dig port's .pre_enable() hook which leads to an oops.
Need to think more how to solve this in a cleaner fashion, but
for now let's just add a NULL check to stop the oopsing.

With discrete graphics system can have both integrated and discrete GPU
handled by i915.
Currently we use a fixed name ("i915") when registering as the uncore PMU
provider which stops working in this case.
To fix this we add the PCI device name string to non-integrated devices
handled by us. Integrated devices keep the legacy name preserving
backward compatibility.
v2:
* Detect IGP and keep legacy name. (Michal)
* Use PCI device name as suffix. (Michal, Chris)
v3:
* Constify the name. (Chris)
* Use pci_domain_nr. (Chris)
v4:
* Fix kfree_const usage. (Chris)
v5:
* kfree_const does not work for modules. (Chris)
* Changed is_igp helper to take i915.
