We are checking cp_irq_count from the wrong hdcp structure which ends up giving timed out errors. We only increment the cp_irq_count of the primary connector's hdcp structure but here in case of multidisplay setup we end up checking the secondary connector's hdcp structure, which will not have its cp_irq_count incremented. This leads to a timed out at CP_IRQ error even though a CP_IRQ was raised. Extract it from the correct intel_hdcp structure. --v2 -Explain why it was the wrong hdcp structure [Jani] Fixes: 8c9e4f68 ("drm/i915/hdcp: Use per-device debugs") Signed-off-by:

With the previous cleanups, the last remaining user of __i915_printk() is i915_probe_error(). Switch that to use drm_dbg() and drm_err() instead, dropping the request to report bugs in the few remaining specific cases. It's not common for drivers to log bug filing requests to begin with, but these cases are in init, which is most likely to be tested in CI and least likely to be hit by end users anyway. Acked-by:

i915_report_error() presently acts as a wrapper for __i915_printk(). In practice, it would be better to use drm level error reporting wherever possible, so replace all uses of i915_report_error() with the equivalent drm_err() call. These cases are not worth having a dedicated wrapper to also print bug reporting info. Replacing the calls leaves i915_report_error() with no users, so remove it. Reviewed-by:

Enable switching between UHBR and non-UHBR link rates on MST links when reducing the link parameters after an LT failure. Reviewed-by:
-
Imre Deak authored
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. Reviewed-by:

Imre Deak authored
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 downstream 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. Reviewed-by:

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. Reviewed-by:
-
Imre Deak authored
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.

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.

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).
