Subject: nouveau optimus dynamic power off
Date: Mon, 29 Jul 2013 16:06:55 +1000 [thread overview]
Message-ID: <1375078019-25358-1-git-send-email-airlied@gmail.com> (raw)
I finally got back to debugging the HDMI audio interactions that
stopped me last time,
This adds switcheroo + nouveau + hda_intel support for turning
off the secondary GPU in optimus laptops, saving a lot of power.
The GPU should come back on for things like lspci on the devices
or for DRI_PRIME= or X starting up.
