https://bugs.freedesktop.org/show_bug.cgi?id=98398 --- Comment #5 from rick.2889 at gmail.com --- Adding pcie_port_pm=off to my kernel command line causes the card to turn off and powertop to report ~7.5W of power usage. According to Lekensteyn this reverts nouveau to the 4.7 and lower behavior of using DSM, so I think this is a regression from using the new method. -- You are receiving this

Hello guys, I've prepared a patch based on my findings for the bbswitch module (https://github.com/Lekensteyn/acpi-stuff/tree/master/bbswitch). This adds a proper check whether a _DSM function is supported or not and make OFF / ON for vga_switcheroo work for nVidia Optimus models. The patch is based against the mainline kernel. It has been tested on my Clevo B7130 laptop running kernel 3.2

Hello, On new Lenovo T440p laptops with new BIOSes (1.16 and further) there is a memory corruption when trying to disable, and then re-enable, nvidia GPU. There is a bugreport for bbswitch ( https://github.com/Bumblebee-Project/bbswitch/issues/78), but this problem shows even when doing disable and re-enable with acpi_call, and nouveau has dynamic power management support too. I have been trying

Hello, I have an Asus laptop, U36SD, with Optimus technology. The discrete gpu is an NVIDIA GeForce GT 520M with 1GB DDR3 VRAM Using Fedora 17; up to kernel 3.3.7-1 I was able to use bumblebee and bbswitch and then running optirun command (as I could do in F16). No more with kernel 3.4. Tried 3.4.0-1.fc17.x86_64, 3.4.2-4.fc17.x86_64 and 3.4.3-1.fc17.x86_64. I already opened a bug against F17:

Since "PCI: Add runtime PM support for PCIe ports", the parent PCIe port can be runtime-suspended which disables power resources via ACPI. This is incompatible with DSM, resulting in a GPU device which is still in D3 and locks up the kernel on resume (on a Clevo P651RA, GTX965M). Mirror the behavior of Windows 8 and newer[1] (as observed via an AMLi debugger trace) and stop using the
