[PATCH 00/14] drm/i915/dp_mst: Enable LT fallback for UHBR<->non-UHBR rates

[Imre Deak]

This patchset enables the link training fallback on MST links between
UHBR and non-UHBR link rates. As a dependency it also switches the
fallback to happen in a link configuration sequence ordered by BW and
makes sure that the MST BW reported via the ENUM_PATH_RESOURCES message
is always up-to-date in the MST topology SW state.

[PATCH 03/14] drm/dp_mst: Simplify the condition when to enumerate path resources

[Imre Deak]

In the
	if (old_ddps != port->ddps || !created)
		if (port->ddps && !port->input)
			ret = drm_dp_send_enum_path_resources();

sequence the first if's condition is true if the port exists already
(!created) or the port was created anew (hence old_ddps==0) and it was
in the plugged state (port->ddps==1). The second if's condition is true
for output ports in the plugged state. So the function is called for an
output port in the plugged state, regardless if it already existed or
not and regardless of the old plugged state. In all other cases
port->full_pbn can be zeroed as the port is either an input for which
full_pbn is never set, or an output in the unplugged state for which
full_pbn was already zeroed previously or the port was just created
(with port->full_pbn==0).

Simplify the condition, making it clear that the path resources are
always enumerated for an output port in the plugged state.

[PATCH 04/14] drm/i915/ddi: For an active output call the DP encoder sync_state() only for DP

[Imre Deak]

If the DDI encoder output is enabled in HDMI mode there is no point in
calling intel_dp_sync_state(), as in that case the DPCD initialization
will fail - as expected - with AUX timeouts. Prevent calling the hook in
this case.

[PATCH 05/14] drm/i915/dp: Initialize the link parameters during HW readout

[Imre Deak]

Initialize the DP link parameters during HW readout. These need to be
up-to-date at least for the MST topology probing, which depends on the
link rate and lane count programmed in DPCD. A follow-up patch will
program the DPCD values to reflect the maximum link parameters before
the first MST topology probing, but should do so only if the link is
disabled (link_trained==false).

[PATCH 06/14] drm/i915/dp: Send only a single modeset-retry uevent for a commit

[Imre Deak]

There are multiple failure cases a modeset-retry uevent can be sent for
a link (TBT tunnel BW allocation failure, unrecoverable link training
failure), a follow-up patch adding the handling for a new case where the
DP MST payload allocation fails. The uevent is the same in all cases,
sent to all the connectors on the link, so in case of multiple failures
there is no point in sending a separate uevent for each failure; prevent
this, sending only a single modeset-retry uevent for a commit.

[PATCH 09/14] drm/i915/dp_mst: Reduce the link parameters in BW order after LT failures

[Imre Deak]

On MST links - at least for some MST branch devices - the list of modes
returned to users on an enabled link depends on the current link
rate/lane count parameters (besides the DPRX link capabilities, any MST
branch BW limit and the maximum link parameters reduced after LT
failures). In particular the MST branch BW limit may depend on the link
rate/lane count parameters programmed to DPCD. After an LT failure and
limiting the maximum link parameters accordingly, users should see a
mode list reflecting these new limits. However with the current fallback
order this isn't ensured, as the new limit could allow for modes
requiring a higher link BW, but these modes will be filtered out due to
the enabled link's lower link BW.

Ensure that the mode list changes in a consistent way after a link
training failure and reducing the link parameters by changing the
fallback order on MST links to happen in BW order.

[PATCH 10/14] drm/i915/dp_mst: Configure MST after the link parameters are reset

[Imre Deak]

The MST topology probing depends on the maximum link parameters -
programmed to DPCD if required by a follow-up patch - so make sure these
parameters are up-to-date before configuring and probing the MST
topology.

most probably, so send a uevent accordinly requesting the user to retry
the modeset. While at it remove the driver specific debug message, there
is already one printed by drm_dp_add_payload_part1().

[PATCH 12/14] drm/i915/dp_mst: Reprobe the MST topology after a link parameter change

[Imre Deak]

The MST link BW reported by branch devices via the ENUM_PATH_RESOURCES
message depends on the channel coding and link rate/lane count
parameters programmed to DPCD. This is the case at least for some branch
devices, while for others the reported BW is independent of the link
parameters. In any case the DP standard requires the branch device to
adjust the returned value to both account for the different way the BW
for FEC is accounted for (included in the returned value for non-UHBR
and not included for UHBR rates) and to limit the returned value to the
(trained) link BW between the source and first downstreaam branch
device, see DP v2.0/v2.1 Figure 2-94, DP v2.1 5.9.7. Presumedly this is
also the reason why the standard requires the DPCD link rate/lane count
values being up-to-date before sending the ENUM_PATH_RESOURCES message,
see DP v2.1 2.14.9.4.

Based on the above reprobe the MST topology after the link is retrained
with new link parameters to make sure that the MST link BW tracked in
the MST topology state (via each topology port's full_pbn value) is
up-to-date.

The next patch will make sure that the MST link BW is also kept
up-to-date if the link is disabled.

[PATCH 13/14] drm/i915/dp_mst: Ensure link parameters are up-to-date for a disabled link

[Imre Deak]

As explained in the previous patch, the MST link BW reported by branch
devices during topology probing/path resources enumeration depends on
the link parameters programmed to DPCD to be up-to-date. After a sink is
plugged this is not ensured, as those DPCD values start out zeroed. The
target link parameters (for a subsequent modeset) are the maximum that
is supported, so make sure these maximum values are programmed before the
topology probing.

So we are trying to avoid calling  intel_dp_sync_state incase intel_encoder_is_dp returns INTEL_OUTPUT_DDI
in that case why are we still keeping the check intel_encoder_is_dp when crtc_state is not present.

intel_encoder_is_dp() returns true if a DP connector is registered using
this DDI encoder. If the output is disabled (so crtc_state==NULL) that's
the only way to determine if the encoder may be used for DP (unless an
HDMI connector is also registered using this same encoder and that's
what is actually used on the given platform). In case the output is
enabled the DP/HDMI mode in crtc_state gives the same answer, but by
checking that instead we avoid calling the DP specific hook if the
encoder is used by HDMI.

link_trained indicates whether the output is enabled or not, which must
be in sync with crtc_state being NULL (output disabled) or not NULL
(output enabled).

Is an exit condition required with some 'x' retry so that this retry doesn't end up in an infinite loop.
For link training failure the link rate/lane count is reduced and when it reaches the least can exit, but for BW allocation failures/payload failure this may not be the case.

On link training failure reducing link rate or lane count is not linear. Sometime we fall from uhbr to hbr and then again with uhbr with lane reduction. So would it be better to have a table/list for the fallback link rate/lane count.

I feel this name could be a little confusing this define here I am assuming the

Do we need to remove this here, I mean why introduce this piece of todo code to begin with specially in this function as reduce_link_params_in_bw_order is being defined in this series in one of the previous patches. Just omit this condition while
defining it

This is an error condition the driver reports (asynchronously) if a
modeset request by userspace/client failed. It would be incorrect not to
report this error, leaving the output in a blank, enabled state.

I think that userspace/client should handle such failures - in the
above case a buggy sink - by disabling the output.

This patch is meant to to keep the current way of reducing the rate and
lane count, just preparing for a follow-up change that adds the
alternetive BW order fallback logic for MST. I think later SST would
need to be switched to the logic as well, for now I didn't want to
change this.

That's basically the rule of containing only one change in one patch.
That rule is for different reasons, one is to help with bisecting an
issue. In the earlier patch you refer to the change is to switch the
fallback logic to happen in BW order, but keeping the behavior not to
switch between UHBR <-> non-UHBR rates as it was before. Here at the end
of the patchset is also the point to enable this rate switching, after
addressing all the dependencies for that.

Can we have a TODO in this function about this?

It would be a bug in userspace to keep modesetting in an infinite loop,
instead of disabling the output; the same could happen already after LT
failures. Adding a workaround for such users wouldn't be simply not
returning any error to the user and is not the topic of this patchset.

Not sure what you mean. I can add a TODO comment to change the fallback
logic on SST links to happen the same way as on MST links, decreasing
the link's BW at each step.

Thanks Lyude for the review.

Thomas, Maxim, Maarten, could you ack merging these 3 DRM core patches
through the i915 tree?

[PATCH v2 09/14] drm/i915/dp_mst: Reduce the link parameters in BW order after LT failures

[Imre Deak]

On MST links - at least for some MST branch devices - the list of modes
returned to users on an enabled link depends on the current link
rate/lane count parameters (besides the DPRX link capabilities, any MST
branch BW limit and the maximum link parameters reduced after LT
failures). In particular the MST branch BW limit may depend on the link
rate/lane count parameters programmed to DPCD. After an LT failure and
limiting the maximum link parameters accordingly, users should see a
mode list reflecting these new limits. However with the current fallback
order this isn't ensured, as the new limit could allow for modes
requiring a higher link BW, but these modes will be filtered out due to
the enabled link's lower link BW.

Ensure that the mode list changes in a consistent way after a link
training failure and reducing the link parameters by changing the
fallback order on MST links to happen in BW order.

v2:
- s/INTEL_DP_MAX_SUPPORTED_LANE_COUNTS/INTEL_DP_MAX_SUPPORTED_LANE_CONFIGS
  and s/num_common_lane_counts/num_common_lane_configs to make the
  difference wrt. max lane counts clearer. (Suraj)
- Add a TODO comment to make the SST fallback logic work the same way as
  MST. (Arun)
- Use sort_r()'s default swap function instead of a custom one.

Thanks for the reviews/acks, patchset is pushed to drm-intel-next, with
Thomas' irc ack for the first 3 DRM core patches.

The failures are unrelated, see below.

There is only an HDMI sink connected, no DP, so the failure is unrelated
to the changes. It's

(i915_pm_rc6_residency:1196) CRITICAL: Failed assertion: ratio > 0.9 && ratio < 1.05
(i915_pm_rc6_residency:1196) CRITICAL: Sysfs RC6 residency counter is inaccurate.

which looks like

Only eDP is connected (so no DP-MST), without any retraining, so can't
see how the changes would relate to this. It's 

<3> [304.416840] e1000e 0000:00:1f.6: PM: pci_pm_suspend(): e1000e_pm_suspend [e1000e] returns -2
<3> [304.425272] e1000e 0000:00:1f.6: PM: dpm_run_callback(): pci_pm_suspend returns -2
<3> [304.432881] e1000e 0000:00:1f.6: PM: failed to suspend async: error -2

aborting the system suspend/resume, seen many times before in CI runs.

Would this take care of the cases where a branch device is present
between source and the sink and
its properly allocating the resources and advertising UHBR capability
from branch to sink. This was a bug earlier
with UHBR on branch device/ MST hub

I suppose you refer to [1].

The patchset as a whole should ensure that the BW reported by branch
devices via the ENUM_PATH_RESOURCES message is correct even across
changing between UHBR <-> non-UHBR link rates between the source and the
first downstream branch devices. More on this are detailed at [2] and
[3]. It looks like this would also address the issue described in [1],
but I couldn't test this yet, as I don't have any hub/dock supporting
UHBR rates.
