Subject: [PATCH v4 00/14] drm/i915: Add support for HDCP 1.4 over MST connectors
Date: Tue, 18 Feb 2020 17:02:28 -0500	[thread overview]
Message-ID: <20200218220242.107265-1-sean@poorly.run> (raw)

From: Sean Paul <seanpaul@chromium.org>

Hey all,
Back with a v4. Rebased on latest drm-tip.

Biggest change was adding the QUERY_STREAM_ENCRYPTION_STATUS check which
ensures not only the link to the first branch is encrypted, but also
that the channel iteself is also protected.

Sean
