[Nouveau] 5.5 kernel: using nouveau or something else just long enough to turn off Quadro RTX 4000 Mobile for hybrid graphics?
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). I now got a newer P73 also with the same hybrid graphics (setup as such in the bios). It runs fine with i915, and I don't need to use external display with nouveau for now (it almost works, but I only see the mouse cursor on the external screen, no window or anything else can get displayed, very weird). 01:00.0 VGA compatible controller: NVIDIA Corporation TU104GLM [Quadro RTX 4000 Mobile / Max-Q] (rev a1) What I need for now is either nouveau, or bbswitch if it still works to turn the nvidia chip off every time I power on/reboot/plug/unplug external power. if I don't load the nouveau module, I get this in powertop: Bad Runtime PM for PCI Device NVIDIA Corporation TU104GLM [Quadro RTX 4000 Mobile / Max-Q] powertop cannot really turn it off and I get The battery reports a discharge rate of 63.0 W If I load the nouveau driver, the chip gets turned off (great), but it's unstable and hard crashes my laptop when I plug/unplug it from power after a few times. This is what I got in my logs after the last crash: intel-lpss 0000:00:15.0: power state changed by ACPI to D3cold intel-lpss 0000:00:15.1: power state changed by ACPI to D3cold snd_hda_intel 0000:00:1f.3: PME# enabled intel-lpss 0000:00:1e.0: power state changed by ACPI to D3cold snd_hda_intel 0000:00:1f.3: power state changed by ACPI to D3hot xhci_hcd 0000:01:00.2: PME# enabled nvidia-gpu 0000:01:00.3: PME# enabled pcieport 0000:05:00.0: PME# enabled xhci_hcd 0000:2c:00.0: PME# enabled pcieport 0000:05:02.0: PME# enabled pcieport 0000:04:00.0: PME# enabled pcieport 0000:00:1c.0: PME# enabled pcieport 0000:00:1c.0: power state changed by ACPI to D3cold nouveau 0000:01:00.0: power state changed by ACPI to D3cold pcieport 0000:00:01.0: PME# enabled pcieport 0000:00:01.0: power state changed by ACPI to D3cold I am using TLP to manage battery use, the driver might not like things getting turned off to save power (although when it works, I can get the laptop down to 10W) Any suggestions on my best way to just keep the nvidia chip off reliably? nouveau? bbswitch? other?

I'd expect some errors about timeouts or something else. Which kernel are you using? There have been some turing-specific fixes recently. Also note that TLP has a problem where it forces the audio sub-function to always-on which prevents the GPU from suspending. Cheers, -ilia

I have #RUNTIME_PM_DRIVER_BLACKLIST="amdgpu mei_me nouveau nvidia pcieport radeon" sauron:~$ lspci |grep -i nvidia 01:00.0 VGA compatible controller: NVIDIA Corporation TU104GLM [Quadro RTX 4000 Mobile / Max-Q] (rev a1) 01:00.1 Audio device: NVIDIA Corporation TU104 HD Audio Controller (rev a1) 01:00.2 USB controller: NVIDIA Corporation TU104 USB 3.1 Host Controller (rev a1) 01:00.3 Serial bus controller [0c80]: NVIDIA Corporation TU104 USB Type-C UCSI Controller (rev a1) So you're saying that I need to blacklist 01:00.1 and without that it hangs when suspending the powered off nvidia chip, which is what I'm experiencing as a hang when I unplug power?
