ERR_NVGPUCTRPERM when use Nvidia Visual Profiler to profile Xavier remotely

[fei.4.xu]

Hi,

I installed nsight eclipse edition (and standalone nsight compute/system) on a host Ubuntu 18 machine.
The installation seems to be ok because I can use nsight system 2021.2.3 already and connect/profile a remote Xavier and get the timeline result.
Then I tried to use Nvidia Visual Profiler, but I have this error:

==15850== NVPROF is profiling process 15850, command: /home/cont/Documents/remote/Debug/remote
==15850== Warning: ERR_NVGPUCTRPERM - The user does not have permission to profile on the target device. See the following link for instructions to enable permissions and get more information: https://developer.nvidia.com/ERR_NVGPUCTRPERM 

I have checked the link of https://developer.nvidia.com/nvidia-development-tools-solutions-err-nvgpuctrperm-nsightcompute

But I don’t know to to how to run the remote project with sudo because it’s launched by nsight.

Thanks.

Hi,

Please set up the password for root account with the below comment.
After that, please log in to Xavier with root to allow the permission.

No timeline for profiler Xavier: nvvp and nsight compute is not working in Jetson Xavier

Hi, Have you setup the root password first? The process should like this: 1.Setup root password $ sudo passwd root 2.Edit /etc/ssh/sshd_config diff --git a/sshd_config b/sshd_config index a32dc1d..d21cacd 100644 --- a/sshd_config +++ b/sshd_config @@ -30,6 +30,7 @@ #LoginGraceTime 2m #PermitRootLogin prohibit-password +PermitRootLogin yes #StrictModes yes #MaxAuthTries 6 #MaxSessions 10 @@ -54,7 +55,7 @@ # To disable tunneled clear text passwords, change to no here! #PasswordAut…

Thanks.
