Subject: [Intel-gfx] i915 MST HDCP code looks broken
Date: Mon, 4 Oct 2021 13:51:34 +0300	[thread overview]
Message-ID: <YVrctgdJ8EYdW9i0@intel.com> (raw)

Hi,

I took a quick peek at intel_dp_add_mst_connector() the other day and
noticed that it calls intel_dp_hdcp_init() and passes in the SST
dig_port. And digging in a bit further that seems to clobber all
kinds of things in dig_port->hdcp_port_data. This looks rather
broken to me.

So has anyone actually thought what happens if you first use
MST on the port, and then later switch to SST on the same port?
