Cannot enter D3 state with dynamic power management on hybrid setup

sfacenda · January 3, 2026, 6:12pm

I’m using the open driver version 590.48.01. I’m on an asus laptop with hybrid setup, using prime offload. I want the dGPU to sleep when not used, but I always see runtime_usage=2 or 1.

Some commands output:

cat /sys/class/drm/card0/device/power/runtime_status /sys/class/drm/card0/device/power_state /sys/class/drm/card0/device/power/runtime_usage

I’m running with NVreg_DynamicPowerManagement=0x02, NVreg_TemporaryFilePath=/var/tmp, NVreg_OpenRmEnableUnsupportedGpus=1, nvidia-drm.modeset=1 nvidia-drm.fbdev=1.

It looks like no one is using the dGPU, but it doesn’t go to sleep, also the memory should be put in sleep or self refresh state but it doesn’t.

The only strange thing I noticed is that nvtop shows an higher memory usage: 0.373Gi/7.996Gi but I don’t understand who allocated that memory (if it’s right). I suspet it’s nvidia_drm.

Looking at the D3 sleep documentation there is no reference to drm and modesetting issue.

I managed to get a constant runtime_usage=1 configuring the nvidia audio device to sleep: 0000:01:00.1 Audio device: NVIDIA Corporation AD107 High Definition Audio Controller (rev a1)

sfacenda · January 6, 2026, 4:32pm

Also, with the closed driver and

options nvidia "NVreg_DynamicPowerManagement=0x02"
options nvidia NVreg_DynamicPowerManagementVideoMemoryThreshold=1024
options nvidia NVreg_S0ixPowerManagementVideoMemoryThreshold=1024
options nvidia NVreg_EnableS0ixPowerManagement=1
options nvidia NVreg_TemporaryFilePath=/var/tmp
options nvidia NVreg_EnableGpuFirmware=0

and `NVreg_PreserveVideoMemoryAllocations=1`it worked for a second, but only one time.

Hi @sfacenda , thanks for reporting this issue.
Could you try the following -

Remove the nvidia-drm.fbdev=1 param
Edit options nvidia "NVreg_DynamicPowerManagement=0x02" to 0x03 or remove it and re-install the driver.
Verify that both /sys/bus/pci/devices/0000:01:00.0/power/control and /sys/bus/pci/devices/0000:01:00.1/power/control are set to auto instead of on.

Also, I don’t think you need the nvidia.NVreg_OpenRmEnableUnsupportedGpus=1 param in your cmdline arguments.
Please help to upload the bug report again if it doesn’t enter into D3 after the above steps, thanks.

sfacenda · January 7, 2026, 9:11am

Ok, I tried with both the open and closed drivers (and GSP disabled), no D3 sadly.

❯ grep . /sys/bus/pci/devices/0000:01:00.*/power/control
/sys/bus/pci/devices/0000:01:00.0/power/control:auto
/sys/bus/pci/devices/0000:01:00.1/power/control:auto
❯ sudo grep . /sys/module/nvidia_drm/parameters/*
/sys/module/nvidia_drm/parameters/fbdev:N
/sys/module/nvidia_drm/parameters/modeset:Y

nvidia-bug-report.log.gz (351.2 KB)

The report is done when using the open drivers.

NVreg_OpenRmEnableUnsupportedGpus is set by my distro when I use the open drivers and it’s not trivial to remove it.

vanditd · January 7, 2026, 1:07pm

Thanks @sfacenda , could you please share the output of cat /proc/fb from your system?

sfacenda · January 7, 2026, 1:25pm

cat /proc/fb
0 i915drmfb

vanditd · January 7, 2026, 2:50pm

Thanks @sfacenda , I think we have one more thing left to check, could you please send the output of :

cat /sys/bus/pci/devices/0000:01:00.0/boot_vga
cat /sys/bus/pci/devices/0000:00:02.0/boot_vga

Have you already tried this? (worked for me)

sfacenda · January 7, 2026, 4:35pm

Yes, no luck for me.

vanditd · January 11, 2026, 12:23pm

Hi @sfacenda , could you try after adding this kernel commandline option initcall_blacklist=sysfb_init ?

sfacenda · January 11, 2026, 4:56pm

Just tried, with all the possible combinations of NVreg_DynamicPowerManagementVideoMemoryThreshold=0/1024, NVreg_PreserveVideoMemoryAllocations=1/0, still Runtime D3 status: Enabled (fine-grained) but

grep . /sys/bus/pci/devices/0000:01:00.0/power/*
/sys/bus/pci/devices/0000:01:00.0/power/async:enabled
grep: /sys/bus/pci/devices/0000:01:00.0/power/autosuspend_delay_ms: Input/output error
/sys/bus/pci/devices/0000:01:00.0/power/control:auto
/sys/bus/pci/devices/0000:01:00.0/power/runtime_active_kids:0
/sys/bus/pci/devices/0000:01:00.0/power/runtime_active_time:273785
/sys/bus/pci/devices/0000:01:00.0/power/runtime_enabled:enabled
/sys/bus/pci/devices/0000:01:00.0/power/runtime_status:active
/sys/bus/pci/devices/0000:01:00.0/power/runtime_suspended_time:0
/sys/bus/pci/devices/0000:01:00.0/power/runtime_usage:1
/sys/bus/pci/devices/0000:01:00.0/power/wakeup:disabled

Sometimes I see runtime_suspend_time:560 or others number <1000.

vanditd · January 14, 2026, 8:50am

Hi @sfacenda , thanks for the update, could you attach a bug report after setting initcall_blacklist=sysfb_init?

Hello @vanditd , any update?

vanditd · April 1, 2026, 5:14am

Hi @sfacenda, sorry for the delay, I will try to repro this locally and provide an update.
