We see some monitors and docks report incorrect hdcp version and capability in first few reads so we read rx_caps three times before we conclude the monitor's or docks HDCP capability --v2 -Add comment to justify the 3 time read loop for hdcp capability[Ankit] Signed-off-by:

Allocate stream id after HDCP AKE stage and not before so that it can also be done during link integrity check. Right now for MST scenarios LIC fails after hdcp enablement for this reason. --v2 -no need for else block in prepare_streams function [Ankit] --v3 -remove intel_hdcp argument from required_content_stream function [Ankit] Signed-off-by:

Whenever LIC fails instead of moving from ENABLED to DESIRED CP property we directly enable HDCP1.4 without informing the userspace of this failure in link integrity check. Now we will just update the value to DESIRED send the event to userspace and then continue with the normal flow of HDCP enablement. Signed-off-by:

Now that we have moved back to direct reads the additional timing is not required hence this can be removed. --v2 -Add Fixes tag [Ankit] Fixes: 3974f9c1 ("drm/i915/hdcp: Adjust timeout for read in DPMST Scenario") Signed-off-by:

Currently we are only checking capability of remote device and not immediate downstream device but during capability check we need are concerned with only the HDCP capability of downstream device. During i915_display_info reporting we need HDCP Capability for both the monitors and downstream branch device if any this patch adds that. --v2 -Use MST Hub HDCP version [Ankit] --v3 -Redefined how we seprate remote and direct read to make sure HDMI shim functions are not touched [Ankit] --v4 - Fix the conditions so that hdcp_info with remote_req true is sent only when encoder is mst [Ankit] --v5 -No need to have the MST Hub version in i915_hdcp_sink_capability[Ankit] Signed-off-by:

Create a remote HDCP capability shim function which can read the remote monitor HDCP capability when in MST configuration. --v2 -Add an assertion to make sure only mst encoder call this remote_cap function [Ankit] --v3 -rename remote_hdcp_cap to remote_hdcp_capability [Jani] --v4 -fix hdcp2_prerequisite check condition -Move intel_dp_hdcp_get_remote_capability to dp_mst shim instead of having it in dp shim [Ankit] Signed-off-by:

Even for MST scenarios we need to do direct reads only on the immediate downstream device the rest of the authentication is taken care by that device. Remote reads will only be used to check capability of the monitors in MST topology. --v2 -Add fixes tag [Ankit] -Derive aux where needed rather than through a function [Ankit] Fixes: ae4f902b ("drm/i915/hdcp: Send the correct aux for DPMST HDCP scenario") Signed-off-by:

If the connected panel supports both DRRS & PSR, driver gives preference to PSR ("DRRS enabled: no"). Even though the hardware supports DRRS, IGT treats ("DRRS enabled: yes") as not capable. Introduce a new entry "DRRS capable" to debugfs i915_drrs_status, so that IGT will read the DRRS capability as "DRRS capable: yes".

This is used to improve package C residency by sending the highest latency tolerance requirement (LTR) when the planes are done with the frame until the next frame programming window (set context latency, window 2) starts.

Commit 1fd4a5a3 ("drm/connector: Rename legacy TV property") failed to update all the users of the struct drm_tv_connector_state mode field, which resulted in a build failure in i915. However, a subsequent commit in the same series reintroduced a mode field in that structure, with a different semantic but the same type, with the assumption that all previous users were updated. Since that didn't happen, the i915 driver now compiles, but mixes accesses to the legacy_mode field and the newer mode field, but with the previous semantics. This obviously doesn't work very well, so we need to update the accesses that weren't in the legacy renaming commit. Fixes: 1fd4a5a3 ("drm/connector: Rename legacy TV property") Reported-by:
