Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
The DSC HW state of DP connectors is read out during driver loading and
system resume in intel_modeset_update_connector_atomic_state(). This
function is called for all connectors though and so the state of DSI
connectors will also get updated incorrectly, triggering a WARN there
wrt. the DSC decompression AUX device.
Fix the above by moving the DSC state readout to a new DP connector
specific sync_state() hook. This is anyway the logical place to update
the connector object's state vs. the connector's atomic state.

The TBT DP tunnel BW request logic in the Thunderbolt Connection Manager
depends on the GFX driver reading out the sink's DPRX capabilities in
response to a long HPD pulse. Since in i915 this read-out can be blocked
by another connector's/encoder's hotplug event handling (which is
serialized by drm_mode_config::connection_mutex), do a dummy DPRX read-out
in the encoder's HPD pulse handler (which is not blocked by other
encoders).

Suspend and resume DP tunnels during system suspend/resume, disabling
the BW allocation mode during suspend, re-enabling it after resume. This
reflects the link's BW management component (Thunderbolt CM) disabling
BWA during suspend. Before any BW requests the driver must read the
sink's DPRX capabilities (since the BW manager requires this
information, so snoops for it on AUX), so ensure this read takes place.

Sync instead of only try-sync non-blocking commits when getting the
active pipes through a given DP port. Atm intel_dp_get_active_pipes()
will only try to sync a given pipe and if that would block ignore the
pipe. This was supposed to avoid link retraining in case a pending
modeset would do that anyway, however that could incorrectly ignore
fastset pipes as well for instance (which don't retraing the link).
The TC port reset path needs to handle all pipes, even if a waiting for
a pending commit would block. To account for the above cases sync all
the pipes unconditionally.
This also prepares for a follow-up change enabling the DP tunnel BW
allocation mode which needs to ensure that all active pipes are synced
and returned from intel_dp_get_active_pipes().
v2:
- Add a separate function to try-sync the pipes. (Ville)
v3:
- Just sync the pipes unconditionally in intel_dp_get_active_pipes().

Add intel_dp_max_link_data_rate() to get the link BW vs. the sink DPRX
BW used by a follow-up patch enabling the DP tunnel BW allocation mode.
The link BW can be below the DPRX BW due to a BW limitation on a link

On shared (Thunderbolt) links with DP tunnels, the modeset may need to
be retried on all connectors on the link due to a link BW limitation
arising only after the atomic check phase. To support this add a helper
function queuing a work to retry the modeset on a given port's connector
and at the same time any MST connector with streams through the same
port. A follow-up change enabling the DP tunnel Bandwidth Allocation
Mode will take this into use.
v2:
- Send the uevent only to enabled MST connectors. (Jouni)

Merge v6.8-rc6 into drm-next
Thomas Zimmermann asked to backmerge -rc6 for drm-misc branches,
there's a few same-area-changed conflicts (xe and amdgpu mostly) that
are getting a bit too annoying.
Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
Commit 47f419e071 ("drm/dp: move intel_dp_vsc_sdp_pack() to generic helper")
and commit b55b88d86f ("drm/dp: drop the size parameter from drm_dp_vsc_sdp_pack()")
were based on top of a tree containing the
commit 31a5b6ed88 ("drm/i915/display: Unify VSC SPD preparation") but
landed in a tree where this commit didn't exist, leaving behind a spurious
case calling for a removed function: intel_dp_vsc_sdp_pack()
Let's convert the remaining case here so we can port this patch to
any tree that doesn't contain
commit 31a5b6ed88 ("drm/i915/display: Unify VSC SPD preparation")
In in kind of merge where this commit does exist, this line here will
be gone anyway and not needed any longer.

Pull drm updates from Dave Airlie:
"This contains two major new drivers:
- imagination is a first driver for Imagination Technologies devices,
it only covers very specific devices, but there is hope to grow it
- xe is a reboot of the i915 GPU (shares display) side using a more
upstream focused development model, and trying to maximise code
sharing. It's not enabled for any hw by default, and will hopefully
get switched on for Intel's Lunarlake.
This also drops a bunch of the old UMS ioctls. It's been dead long
enough.
amdgpu has a bunch of new color management code that is being used in
the Steam Deck.
amdgpu also has a new ACPI WBRF interaction to help avoid radio
interference.

Glitches deasserting the connector HPD line can lead to incorrectly
detecting a disconnect event (a glitch asserting the line will only
cause a redundant connect->disconnect transition). The source of such a
glitch can be noise on the line or a 0.5ms-1ms MST IRQ_HPD pulse. TypeC
ports in the DP-alt or TBT-alt mode filter out these glitches inernally,
but for others the driver has to do this. Make it so by polling the HPD
line on these connectors for 4 ms.

Add hooks to intel_digital_port to lock and unlock the port and add a
helper to check the connector's detect status while the port is locked
already. This simplifies checking the connector detect status in
intel_dp_aux_xfer() and intel_digital_port_connected() in the next two
patches aborting AUX transfers on all DP connectors (except eDP) and
filtering HPD glitches.

As described in the previous patch, an unexpected connector
detection/modeset started from the intel_hotplug::hotplug_work can
happen during the driver init/shutdown sequence. Prevent these by
disabling the queuing of and flushing all the intel_hotplug work that
can start them at the beginning of the init/shutdown sequence and allow
the queuing only while the display is in the initialized state.
Other work items - like the intel_connector::modeset_retry_work or the
MST probe works - are still enabled and can start a detection/modeset,
but after the previous patch these will be rejected. Disabling these
works as well is for a follow-up patchset.

After an HPD IRQ storm on a connector intel_hpd_irq_storm_detect() will
set the connector's HPD pin state to HPD_MARK_DISABLED and the IRQ gets
disabled. Subsequently intel_hpd_irq_storm_switch_to_polling() will
enable polling for these connectors, setting the pin state to
HPD_DISABLED, but only if the connector's base.polled field is set to
DRM_CONNECTOR_POLL_HPD. intel_hpd_irq_storm_reenable_work() will
reenable the IRQ - after 2 minutes - if the pin state is HPD_DISABLED.
The connectors will be created with their base.polled field set to 0,
which gets initialized only later in i915_hpd_poll_init_work() (using
intel_connector::polled). If a storm is detected on a connector after
it's created and IRQs are enabled on it - by intel_hpd_init() - and
before its bease.polled field is initialized in the above work, the
connector's HPD pin will stay in the HPD_MARK_DISABLED state - leaving
the IRQ disabled indefinitely - and polling will not get enabled on it as
intended.
I can't see a reason for initializing base.polled in a delayed manner,
so do this already when creating the connector, to prevent the above
race condition.

Apparently some BXT/GLK systems have DSI panels whose timings
don't agree with the normal cpu transcoder hblank>=32 limitation.
This is perhaps fine as there are no specific hblank/etc. limits
listed for the BXT/GLK DSI transcoders.
Move those checks out from the global intel_mode_valid() into
into connector specific .mode_valid() hooks, skipping BXT/GLK
DSI connectors. We'll leave the basic [hv]display/[hv]total
checks in intel_mode_valid() as those seem like sensible upper
limits regardless of the transcoder used.

Unfortunately even the HPD based detection added in
commit cfe5bdfb27 ("drm/i915: Check HPD live state during eDP probe")
fails to detect that the VBT's eDP/DDI-A is a ghost on
Asus B360M-A (CFL+CNP). On that board eDP/DDI-A has its HPD
asserted despite nothing being actually connected there :(
The straps/fuses also indicate that the eDP port is present.
So if one boots with a VGA monitor connected the eDP probe will
mistake the DP->VGA converter hooked to DDI-E for an eDP panel
on DDI-A.
As a last resort check what kind of DP device we've detected,
and if it looks like a DP->VGA converter then conclude that
the eDP port should be ignored.
