It looks like the snd-hda-intel code can now detect HDMI / DP ports on an Nvidia card on Optimus laptops, and that powers up part of the second GPU, even when no nouveau or nvidia modules are present. That was increasing the power consumption, _not_ i915's changes with GuC. Sorry for the incorrect bug report, and thanks for the follow ups.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
