Public bug reported: This AMD 3-core + Radeon runs really hot, and I'm trying to maximize battery life.
When I try radeon.dpm=1, I get display glitching every few seconds when the dpm switches displays. I haven't found any way to force dpm to keep the discrete display completely turned off, both to save power and to stop the glitching. Among other problems, the mere existence of HDMI audio keeps waking up the discrete GPU, both wasting power & glitching the display. So I tried radeon.audio=0. I don't think it helps, but I left it in. The only way to really kill the HDMI audio problems is to blacklist snd_hda_intel, but that kills _all_ of my audio (except Bluetooth audio). So I had to un-blacklist snd_hda_intel. So I'm using radeon.dpm=0. If radeon.runpm=1, I still get problems. So I'm using radeon.runpm=0. This works pretty well; I've gotten the temperature down to 68 degrees or so, but this is still too hot. If I turn off the discrete graphics completely using echo OFF > /sys/kernel/debug/vgaswitcheroo/switch this works quite well -- I can get the temperature down to 64 degrees or so -- but now my log fills up with complaints that my radeon discrete driver isn't turned on. (I'll send you another report showing you this.) I want to be able to operate this HP laptop in the most power-saving way -- by completely turning off the discrete radeon GPU. Could you provide any suggestions about how to do this? Thanks very much.
