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

Hi Lukas, Sorry for the delay, I finally found some time to reviewd and test the patches and found some issues (some of them might already be present in v4.15 without your patches though, I did not try). Test environment: - Branch switcheroo_devlink_v2 (commit v4.15-20-gb33d50c5c6ad) - Laptop: Clevo P651RA (nouveau uses PR3), lspci: 00:01.0 PCI bridge [0604]: Intel Corporation Xeon E3-1200

Check whether the kernel really supports power resources for a device, otherwise the power might not be removed when the device is runtime suspended (DSM should still work in these cases where PR does not). This is a workaround for a problem where ACPICA and Windows 10 differ in behavior. ACPICA does not correctly enumerate power resources within a conditional block (due to delayed execution of

Howdy, So, I have a Thinkpad P70 with hybrid graphics. 01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M600M] (rev a2) that one works fine, I can use i915 for the main screen, and nouveau to display on the external ports (external ports are only wired to nvidia chip, so it's impossible to use them without turning the nvidia chip on).
