Problems with nvtop on dual GPU (Intel+Nvidia)

[ibobak]

I have MSI Titan GT77 HX 13VI laptop with two video cards:

/$ lspci | grep -i vga
0000:00:02.0 VGA compatible controller: Intel Corporation Raptor Lake-S UHD Graphics (rev 04)
0000:01:00.0 VGA compatible controller: NVIDIA Corporation GN21-X11 [GeForce RTX 4090 Laptop GPU] (rev a1)

I am getting this message when running nvtop:

This version of Nvtop is missing support for reporting Intel GPU memory, power, fan and temperature
<Don't Show Again> <Ok>

Press Enter to select, arrows ">" and "<" to switch optionsnvtop: ./src/extract_gpuinfo_intel.c:228: parse_drm_fdinfo_intel: 
Assertion `!cache_entry_check && "We should not be processing a client id twice per update"' failed.

I want to mention that after reboot nvtop works fine for some time (even after the message that it won't work for intel card). But in 1 or 2 hours of work it stops working, and when launching it again I am getting a message as above.

May I ask you a question: is is possible to somehow unplug monitoring the Intel GPU and to start monitoring ONLY the Nvidia GPU? Is there some option? Or maybe I can unplug this in the source code somehow and make a custom build for myself? If yes, would you be so kind as to tell how?

I truly don't need to look at intel card: I am interesting to monitor only my nvidia card. Thanks in advance.

Duplicate of #197

Have you tried this?

sudo setcap cap_perfmon=+ep /usr/bin/nvtop

Also make sure that you have intel_gpu_top installed and set the same for this utility as well.

sudo setcap cap_perfmon=+ep /usr/bin/intel_gpu_top

You can select which GPU is monitored through the F2 menu too.

The Intel limitation comes from the driver not providing some metrics yet.

I'll close this for now. Missing info related to #197 Feel free to re-open if you feel like I am missing something.
