No connector found with HDCP capability
Subtest atomic: SKIP (0.000s)
Comment 2 Uma Shankar 2019-07-10 18:33:21 UTC 
This is expected if we don't connect a HDCP capable monitor to DUT.  Looks like we are executing these tests on non HDCP monitors and hitting this error. If someone can confirm that this indeed is the case, then we can close this as expected behavior and this should be a legitimate skip.
Comment 3 Lakshmi 2019-07-11 05:50:35 UTC 
@Tomi, Can you confirm if the monitor connected to icl-u4 is HDCP capable?
Comment 4 Ramalingam C 2019-07-11 12:19:28 UTC 
icl-u4 is newly added? couldn't find at https://intel-gfx-ci.01.org/hardware.html

If this fi-icl-u4 stands for fi-icl-y then this is expected as only eDP is connected to the machine and no HDMI/DP panel is there.
Comment 5 Tomi Sarvela 2019-07-11 14:19:40 UTC 
Host fi-icl-u4 has two USB-C ports connected to Chamelium, through one HDMI and one DP dongle.

Chamelium is (to my knowledge) not HDCP capable.

BA Chameleon Board supports HDCP 1.4 on HDMI connector and  it does not HDCP capable on DP connector.

Comment 8 Anshuman Gupta 2019-07-19 05:37:49 UTC 
From the DMESG logs https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_322/fi-icl-u4/igt@kms_content_protection@atomic-dpms.html
it evident that only DP3 connector was connected and there was no HDMI connecotr conencted. which indicates it is a vaild skip.
Comment 9 Ramalingam C 2019-07-19 05:40:35 UTC 
Based on the above system info and the results from debugging, Marking this as NOTABUG.

Ram/Anshuman, Are these skips are valid on ICL Shards?
Comment 12 Anshuman Gupta 2019-08-07 08:34:24 UTC 
the https://intel-gfx-ci.01.org/hardware/shard-iclb*/i915_display_info.txt logs indicates that all of these icl shards system has only eDP output, therefore these skips are valid.

Comment 14 Lakshmi 2019-09-09 10:05:45 UTC 
@Anshuman/Ram,

This is an expected behavior on fi-icl-u4, shard-iclb*,fi-icl-guc and icl-dsi as these are connected to either eDP panel or dsi panel but not connected HDMI/DP.

But, fi-icl-u2 and fi-icl-u3 are connected through HDMI and DP. So, this bug is valid for fi-icl-u2 and fi-icl-u3?
Comment 15 Jani Saarinen 2019-09-09 10:57:45 UTC 
on u2 there is chamelium as in u4 too. So only u3 has real monitor.

@Anshuman/Ram How about U3? skips are valid on u3?

From https://intel-gfx-ci.01.org/hardware/fi-icl-u3/i915_display_info.txt, we can say connector 197: type DP-1 and connector 210: type HDMI-A-2 are connected to HDCP1.4 capable display panels.

Atleast we shouldn't be seeing this "No connector found with HDCP capability" for this icl-u3.

Possibily when IGT tries to read Panel is not ready with that register value, possibility due to just completed modeset. @anshuman we might want to introduce a retry for capability read!? But is it frequent issue or sporadic in nature!?

This issue is 100% reproducible on fi-icl-u3. Here is the latest failure.
https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_364/fi-icl-u3/igt@kms_content_protection@content_type_change.html

So, can I create a separate issue for fi-icl-u3 and closing this issue as expected behavior as these monitor's doesn't have HDCP capable monitors?
