How to turn on (or prevent turning off) PCI devices?

REDDit - How do I turn off PCI devices? How to turn on or prevent turning off PCI devices? How do I tell Linux to disable and power down these devices without turning them off in my BIOS like they are now, if possible, because then I have to restart my computer to use any of them. As it stands, I still haven't managed to power down: Firewire USB connection to webcam sound card. How do I tell Linux to disable and power down these devices? Is it true that any PCI slot can be physically powered down? My current idle power consumption is 7.9 watts plus the screen. (10.0W at min. brightness). Also, how do I set the screen timeout to ten seconds? gconf editor isn't honoring it when I set it to that. Will switching from nVidia to Nouvea Could you tell me how to turn off PCI power for a device? The followings are the methods I tired. Method.1. Turn off # echo "0" > /sys/bus/pci/slots/"SLOT No."/power turn on # echo "1" > /sys/bus/pci/slots/"SLOT No."/power. Method.2. Unbind. 0000:0c:00.0 is device ID. # echo -n "0000:0c:00.0" > /sys/bus/pci/drivers/"DEVICE NAME"/unbind Bind. # echo -n "0000:0c:00.0" > How do I ensure that this specific PCI device is never automatically activated, without disabling its driver altogether? -edit- The module was renamed recently, now the following works from userland: echo "0000:00:1a.0" > /sys/bus/pci/drivers/ehci-pci/unbind. Still, I'm looking for a way to stop the kernel from binding that device in the first place. linux drivers. Share. The Nvidia driver turns off the remaining 3 devices during boot when the intel profile is selected. The Nvidia driver turns on the remaining 3 devices during boot when the nvidia profile is selected (my guess, but it could be either). I’m fairly comfortable around Linux but this is a completely new part of Linux for me. If my research is correct it’s probably gonna be some ACPI calls, but my knowledge doesn’t reach far enough to find out which ACPI calls those should be. I’d appreciate any pointers as to what’s indeed happening and how I can get all 4 PCI devices to show up with the intel prof Using lspci -vv to identify a device's PCI slot that you want to disable, it sounded like you could use this command to turn that slot's device off:/sys/bus/pci/drivers/"DEVICE NAME"/bind. Method.3. Remove. I think that devices like these two: that doesn't have a subclass or even a device name, aren't recognized by MacOS and so they are there only to consume energy. I don't know what SPI controller is and if it can be enabled or disabled somehow (pci8086,9da4).

How do I know if it works? It's created basing on the Bumblebee Method that should work for every PCI device, and I2C2 correctly has a PS3() method in my DSDT. I hope someone who's better than my in ACPI could give a good idea. Have a nice day! Cutting off power to individual PCIe slots would require a significant amount of additional power management hardware on PC motherboards. None of this hardware would ever be used in normal operation, so there would be no benefit to the added cost (and hardware complexity) of such a design.
