drm/display/dp_mst: Move all payload info into the atomic state Now that we've finally gotten rid of the non-atomic MST users leftover in the kernel, we can finally get rid of all of the legacy payload code we have and move as much as possible into the MST atomic state structs. The main purpose of this is to make the MST code a lot less confusing to work on, as there's a lot of duplicated logic that doesn't really need to be here. As well, this should make introducing features like fallback link retraining and DSC support far easier. Since the old payload code was pretty gnarly and there's a Lot of changes here, I expect this might be a bit difficult to review. So to make things as easy as possible for reviewers, I'll sum up how both the old and new code worked here (it took me a while to figure this out too!). The old MST code basically worked by maintaining two different payload tables - proposed_vcpis, and payloads. proposed_vcpis would hold the modified payload we wanted to push to the topology, while payloads held the payload table that was currently programmed in hardware. Modifications to proposed_vcpis would be handled through drm_dp_allocate_vcpi(), drm_dp_mst_deallocate_vcpi(), and drm_dp_mst_reset_vcpi_slots(). Then, they would be pushed via drm_dp_mst_update_payload_step1() and drm_dp_mst_update_payload_step2(). Furthermore, it's important to note how adding and removing VC payloads actually worked with drm_dp_mst_update_payload_step1(). When a VC payload is removed from the VC table, all VC payloads which come after the removed VC payload's slots must have their time slots shifted towards the start of the table. The old code handles this by looping through the entire payload table and recomputing the start slot for every payload in the topology from scratch. While very much overkill, this ends up doing the right thing because we always order the VCPIs for payloads from first to last starting timeslot. It's important to also note that drm_dp_mst_update_payload_step2() isn't actually limited to updating a single payload - the driver can use it to queue up multiple payload changes so that as many of them can be sent as possible before waiting for the ACT. This is -technically- not against spec, but as Wayne Lin has pointed out it's not consistently implemented correctly in hubs - so it might as well be. drm_dp_mst_update_payload_step2() is pretty self explanatory and basically the same between the old and new code, save for the fact we don't have a second step for deleting payloads anymore -and thus rename it to drm_dp_mst_add_payload_step2(). The new payload code stores all of the current payload info within the MST atomic state and computes as much of the state as possible ahead of time. This has the one exception of the starting timeslots for payloads, which can't be determined at atomic check time since the starting time slots will vary depending on what order CRTCs are enabled in the atomic state - which varies from driver to driver. These are still stored in the atomic MST state, but are only copied from the old MST state during atomic commit time. Likewise, this is when new start slots are determined. Adding/removing payloads now works much more closely to how things are described in the spec. When we delete a payload, we loop through the current list of payloads and update the start slots for any payloads whose time slots came after the payload we just deleted. Determining the starting time slots for new payloads being added is done by simply keeping track of where the end of the VC table is in drm_dp_mst_topology_mgr->next_start_slot. Additionally, it's worth noting that we no longer have a single update_payload() function. Instead, we now have drm_dp_mst_add_payload_step1|2() and drm_dp_mst_remove_payload(). As such, it's now left it up to the driver to figure out when to add or remove payloads. The driver already knows when it's disabling/enabling CRTCs, so it also already knows when payloads should be added or removed. Changes since v1: * Refactor around all of the completely dead code changes that are happening in amdgpu for some reason when they really shouldn't even be there in the first place… :\ * Remove mention of sending one ACT per series of payload updates. As Wayne Lin pointed out, there are apparently hubs on the market that don't work correctly with this scheme and require a separate ACT per payload update. * Fix accidental drop of mst_mgr.lock - Wayne Lin * Remove mentions of allowing multiple ACT updates per payload change, mention that this is a result of vendors not consistently supporting this part of the spec and requiring a unique ACT for each payload change. * Get rid of reference to drm_dp_mst_port in DC - turns out I just got myself confused by DC and we don't actually need this. Changes since v2: * Get rid of fix for not sending payload deallocations if ddps=0 and just go back to wayne's fix Signed-off-by: Lyude Paul <lyude@redhat.com> Cc: Wayne Lin <Wayne.Lin@amd.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Fangzhi Zuo <Jerry.Zuo@amd.com> Cc: Jani Nikula <jani.nikula@intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Sean Paul <sean@poorly.run> Acked-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220817193847.557945-18-lyude@redhat.com

drm/i915/hdcp: reuse rx_info for mst stream type1 capability check On some MST docking stations, rx_info can only be read after RepeaterAuth_Send_ReceiverID_List and the RxStatus READY bit is set otherwise the read will return -EIO. This behavior causes the mst stream type1 capability test to fail to read rx_info and determine if the topology supports type1 and fallback to type0. To fix this, check for type1 capability when we receive rx_info within the AKE flow when we read RepeaterAuth_Send_ReceiverID_List instead of an explicit read just for type1 capability checking. This does require moving where we set stream_types to after hdcp2_authenticate_sink() when we get rx_info but this occurs before we do hdcp2_propagate_stream_management_info. Also, legacy HDCP 2.0/2.1 are not type 1 capable either so check for that as well. Changes since v5: - rename intel_set_stream_types() to intel_hdcp_prepare_streams() (Anshuman) Changes since v4: - move topology_type1_capable to intel_digital_port and rename it as hdcp_mst_type1_capable (Anshuman) - make a helper function intel_set_stream_types() to set stream types in hdcp2_authenticate_and_encrypt() (Anshuman) - break on failure to set stream types and retry instead of returning - remove no longer used declaration for streams_type1_capable() Changes since v2: - Remove no longer used variables in _intel_hdcp2_enable() Signed-off-by: Juston Li <juston.li@intel.com> Reviewed-by: Ramalingam C <ramalingam.c@intel.com> Reviewed-by: Anshuman Gupta <anshuman.gupta@intel.com> Tested-by: Suraj K <suraj.kandpal@intel.com> Signed-off-by: Anshuman Gupta <anshuman.gupta@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210819184835.1181323-4-juston.li@intel.com

drm/i915/display: rename display version macros While converting the rest of the driver to use GRAPHICS_VER() and MEDIA_VER(), following what was done for display, some discussions went back on what we did for display: 1) Why is the == comparison special that deserves a separate macro instead of just getting the version and comparing directly like is done for >, >=, <=? 2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for brevity. If we remove the current users of IS_DISPLAY_VER(), we could actually repurpose it for a range check With (1) there could be an advantage if we used gen_mask since multiple conditionals be combined by the compiler in a single and instruction and check the result. However a) INTEL_GEN() doesn't use the mask since it would make the code bigger everywhere else and b) in the cases it made sense, it also made sense to convert to the _RANGE() variant. So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER() users to use == and != operators. Aside from the definition changes, this was done by the following semantic patch: @@ expression dev_priv, E1; @@ - !IS_DISPLAY_VER(dev_priv, E1) + DISPLAY_VER(dev_priv) != E1 @@ expression dev_priv, E1; @@ - IS_DISPLAY_VER(dev_priv, E1) + DISPLAY_VER(dev_priv) == E1 @@ expression dev_priv, from, until; @@ - IS_DISPLAY_RANGE(dev_priv, from, until) + IS_DISPLAY_VER(dev_priv, from, until) Cc: Jani Nikula <jani.nikula@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> [Jani: Minor conflict resolve while applying.] Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20210413051002.92589-4-lucas.demarchi@intel.com

drm/i915: Don't fully disable HDCP on a port if multiple pipes are using it This patch is required for HDCP over MST. If a port is being used for multiple HDCP streams, we don't want to fully disable HDCP on a port if one of them is disabled. Instead, we just disable the HDCP signalling on that particular pipe and exit early. The last pipe to disable HDCP will also bring down HDCP on the port. In order to achieve this, we need to keep a refcount in intel_digital_port and protect it using a new hdcp_mutex.

drm/i915: Protect workers against disappearing connectors This patch adds some protection against connectors being destroyed before the HDCP workers are finished. For check_work, we do a synchronous cancel after the connector is unregistered which will ensure that it is finished before destruction. In the case of prop_work, we can't do a synchronous wait since it needs to take connection_mutex which could cause deadlock. Instead, we'll take a reference on the connector when scheduling prop_work and give it up once we're done.

drm/i915/hdcp: Update CP as per the kernel internal state Content Protection property should be updated as per the kernel internal state. Let's say if Content protection is disabled by userspace, CP property should be set to UNDESIRED so that reauthentication will not happen until userspace request it again, but when kernel disables the HDCP due to any DDI disabling sequences like modeset/DPMS operation, kernel should set the property to DESIRED, so that when opportunity arises, kernel will start the HDCP authentication on its own. Somewhere in the line, state machine to set content protection to DESIRED from kernel was broken and IGT coverage was missing for it. This patch fixes it. v2: - Fixing hdcp CP state in connector atomic check function intel_hdcp_atomic_check().

drm/i915: Wrappers for display register waits To reduce the number of explicit dev_priv->uncore calls in the display code ahead of the introduction of dev_priv->de_uncore, this patch introduces a wrapper for one of the main usages of it, the register waits. When we transition to the new uncore, we can just update the wrapper to point to the appropriate structure. Since the vast majority of waits are on a set or clear of a bit or mask, add set & clear flavours of the wrapper to simplify the code.

drm: Add Content protection type property This patch adds a DRM ENUM property to the selected connectors. This property is used for mentioning the protected content's type from userspace to kernel HDCP authentication. Type of the stream is decided by the protected content providers. Type 0 content can be rendered on any HDCP protected display wires. But Type 1 content can be rendered only on HDCP2.2 protected paths. So when a userspace sets this property to Type 1 and starts the HDCP enable, kernel will honour it only if HDCP2.2 authentication is through for type 1. Else HDCP enable will be failed. Pekka have completed the Weston DRM-backend review in https://gitlab.freedesktop.org/wayland/weston/merge_requests/48 and the UAPI for HDCP 2.2 looks good. The userspace is accepted in Weston. v2: cp_content_type is replaced with content_protection_type [daniel] check at atomic_set_property is removed [Maarten] v3: %s/content_protection_type/hdcp_content_type [Pekka] v4: property is created for the first requested connector and then reused.
