HDCP Log plus kernel log
-- system architecture: x86-64
-- kernel version: 5.0.0-rc6 from <a href="http://cgit.freedesktop.org/drm-tip">http://cgit.freedesktop.org/drm-tip</a>
-- Linux distribution: Ubuntu 18.04.1 LTS
-- Machine or mother board model: Intel Kaby Lake
-- Display connector: HDMI
-- Test Device: SL-8800 HDCP Compliance Instrument
Two HDCP Compliance test cases failed when hdp_time is set to 100ms in SL-8800
Test Suite.
However, these two test cases passed when hpd_time is set to 3s.
On Leaf Hill Yocto, all hdcp compliance test cases are able to pass with
hpd_time 100ms. Yocto is still with kernel 4.14.
Attached is the compliance log with kernel log after enabling 0xe >
/sys/module/drm/parameters/debug.</pre>
