Yes. This was supposed to work with WAKEEN bits, but this didn't work as expected, after all.
But this applies only to HDMI codecs and the power well, right? Analog controllers could go into D3 and WAKEEN would wake them up? Or did we never get that working either?
Well, the analog codec wakeup never worked in my tests. Maybe some hardware works, who knows.
So essentialy both for analog and hdmi this never works reliably ? I was under the impression taht this was working okay
Anyhow, I went searching in the video drivers for things to match on, inspired by your thoughts about submitting information from the graphics driver to the audio driver. See new attached patch (still writing blind drafts). Let me know what you think.
Thanks, this looks promising!
I think "connector->name" seems what the most reasonable thing to export to userspace to indicate what gfx output is related to which audio nid, and the port being what maps 1-to-1 to a nid - we'll use that for our own lookup (this lookup might differ between hardware generations).
Yeah, this mapping is the unresolved mystery. This mythos has to be revealed by Intel people.
Are you talking about nid to connctor name mapping or something else?
