The cooling maps are experimental - it seems to work well for me without the fan speed varying too much, but what I've noticed with fewer entries in the map is instability in the fan speed - it continually toggles between two fan speeds as the temperature rises and falls due to the different fan speed. Hence, this is more for discussion at this point (and in any case, -final is likely to be released today.) .../dts/marvell/armada-8040-clearfog-gt-8k.dts | 125 ++++++++++++ arch/arm64/boot/dts/marvell/armada-cp11x.dtsi | 6 + drivers/gpio/gpio-mvebu.c | 220 ++++++++++++++------- 3 files changed, 275 insertions(+), 76 deletions(-) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 10.2Mbps down 587kbps up
