https://bugs.freedesktop.org/show_bug.cgi?id=98398 --- Comment #3 from rick.2889 at gmail.com --- Created attachment 127486 --> https://bugs.freedesktop.org/attachment.cgi?id=127486&action=edit New dmesg output after manually turning on power management So Lekensteyn asked me to run a few commands to also shut off the bus the GPU is on. If I do so and then proceed by running powertop

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

https://bugs.freedesktop.org/show_bug.cgi?id=98398 --- Comment #6 from rick.2889 at gmail.com --- Booting without pcie_port_pm=off, while blacklisting nouveau on boot, then executing: echo 0 > /sys/bus/pci/devices/0000:01:00.0/d3cold_allowed && modprobe nouveau also causes powertop to report a ~7.5W value. -- You are receiving this mail because: You are the assignee for the bug.

Hi PCI/ACPI PM experts, Since Linux 4.8, nouveau switched to rely on the PCIe port driver to transition to D3cold. This however does not happen for an Acer Aspire V7-582PG (Haswell, NVIDIA GTX 750M) from Rick. Any idea why? acpidump, lspci, dmesg and other details can be found in the linked bug below.

https://bugs.freedesktop.org/show_bug.cgi?id=98398 --- Comment #11 from Peter Wu <peter at lekensteyn.nl> --- So 4.7 and before used the "DSM" method on runtime-suspend: - \_SB.PCI0.RP05.PEGP._DSM would be invoked to enable Optimus - \_SB.PCI0.RP05.PEGP._PS3 is then invoked which would enter D3cold (note, this method is still used in 4.8 on older laptops or with the

https://bugs.freedesktop.org/show_bug.cgi?id=98398 --- Comment #14 from Peter Wu <peter at lekensteyn.nl> --- Rick, were you actually able to suspend the system with kernel 4.7 and nouveau? Bug 98582 has a similar acpidump and claims that v4.7 also failed to suspend (actually, resume). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part

https://bugs.freedesktop.org/show_bug.cgi?id=98398 --- Comment #16 from Peter Wu <peter at lekensteyn.nl> --- Rick reported that system suspend did not work before the patch either, so there is no regression in that sense. ACPICA developers are faster than expected, can you test these three patches: https://bugs.acpica.org/show_bug.cgi?id=1333#c45 -- You are receiving this mail because:
