You are saying that the HPD line state is available in the register
called SDEIIR in the code?  The documentation only describes pulse
detection bits in this register, not anything directly reflecting the
line state.  The same is true of PCH_PORT_HOTPLUG/SHOTPLUG_CTL.

Testing did not show these registers, or others in the same range,
reflecting the HPD line state.

Hence my question.
