Command Line Control - Linux Only

GPU Performance Counter control requires Linux display driver 418.43 or later.

Unload the old modules.

Before you can insert the module with the key set/unset, you first need to stop the window manager, and unload all nvidia-based modules. So as root, or with sudo:

\# The following assumes a systemd-based distribution. For non-systemd-based distributions, a different procedure is required.

systemctl isolate multi-user \# Stop the window manager.

modprobe -r nvidia\_uvm nvidia\_drm nvidia\_modeset nvidia-vgpu-vfio nvidia \# Unload dependent modules

Specify the access you desire: Insert the modules with the registry key set/unset.:

To require administrative privileges (CAP\_SYS\_ADMIN capability set) to profile using NVIDIA GPU performance counters

modprobe nvidia NVreg\_RestrictProfilingToAdminUsers=1 \[1\]\[4\]\[7\]

Or, to allow any user to profile using NVIDIA GPU performance counters

modprobe nvidia NVreg\_RestrictProfilingToAdminUsers=0 \[2\]\[4\]\[7\]

\[1\] Alternatively, A file containing 'options nvidia "NVreg\_RestrictProfilingToAdminUsers=1"' may be saved to /etc/modprobe.d \[3\]\[5\]

\[2\] Alternatively, A file containing 'options nvidia "NVreg\_RestrictProfilingToAdminUsers=0"' may be saved to /etc/modprobe.d \[3\]\[5\]

\[3\] A reboot may be required in order for this to take effect, but these settings will be persisted

\[4\] These settings will not be persisted after a reboot.

\[5\] On some systems (or when using a deb to install), it may be necessary to rebuild the initrd after writing a configuration file to /etc/modprobe.d\[6\]

\[6\] When rebuilding the initrd, running “update-initramfs -u” is also required.

\[7\] On Ubuntu systems, when installing via the distro-native packages, the kernel module gets

renamed from nvidia to nvidia-xxx, and then nvidia is aliased to nvidia-xxx

(where xxx is the major number of the driver. So a 418.67 driver would use nvidia-418)
