Support for Intel Arc Graphics 130/140V

[adrianboguszewski]

When I use nvtop for my latest Intel Core Ultra 258V I can see "No GPU to monitor". Hence, I'm kindy ask for that implementation :)

Ubuntu 24.10 with kernel 6.11.0

Hi, I was just wondering, are you compiling from the latest commit? It sounds like it's using the xe driver which support for isn't in a release yet, but is already implemented.

I just compiled it from master branch, it works on my 258V laptop.

But the MEM TEMP POW shows N/A.

Hi @g0ne150, thanks! I'm glad it works!

But the MEM TEMP POW shows N/A.

The memory frequency, and temperature isn't exposed by the driver, and I don't believe the power usage is visible on integrated graphics (it works on discrete cards though).

If I am wrong please let me know though; especially since @adrianboguszewski looks to work at Intel and might know something I don't 😉.

@BartoszDunajski could you comment on the memory, temperature and power values? :)

Hi I see something similar, but only for memory with the i915 driver in use.

Here if I run as root user it's all working but as my user I don't see memory utilization?

Oh and the Fan rpm speed is all funky....

[Steve-Tech]

Hi @malcolmlewis,

Intel requires CAP_PERFMON or CAP_SYS_ADMIN capabilities to access the total memory usage which is why it only shows when run as root, but you can run sudo setcap cap_perfmon=ep <path to nvtop> to grant the permissions for a non-root user.

As for the fan speed, what does sensors or the relevant sysfs file say?

[malcolmlewis]

@Steve-Tech I did wonder about that, setcap cap_perfmon=ep /usr/bin/nvtop resolved 😉

I had to tweak the configs as best I could for sensors output based on a visible look at the fans. I need a tachometer to really check!

compute fan1  @/16,  16*@
label fan1 "ARC GPU Fan"

[Steve-Tech]

@malcolmlewis Damn that's interesting, my A770's values seem realistic, but I also don't have a tachometer to check.

[malcolmlewis]

@Steve-Tech I also have an Sparkle A310 ELF (The A380 is an AsRock) even that one I'm a bit suspect of.... but it does track with the sensors output.

@Steve-Tech I currently have an Intel Arc B570 GPU and wanted to monitor its usage in Ubuntu 24.10. However, nvtop gives me the result "No GPU to monitor." I was wondering if the latest commit supports this Arc B570 GPU. Is there something I can look into to fix this?

I know this specific GPU uses the xe driver which, as you mentioned, support has been implemented for in the repo. I know this is a fairly new GPU. Appreciate any help!

Hey @AbelKel,

Ubuntu 24.10 is still packaging nvtop 3.1.0, while 3.2.0 is required for xe support.

Try using the AppImage on the releases page, or compiling it yourself. You should also be able to download the deb packaged for questing, but mixing packages from other releases can cause issues.

If you are already running 3.2.0, could you post (or email like before) a sudo lspci -vvv.

Edit: Sorry I didn't see that you are compiling from the latest commit. Can you double check that it actually installed properly with nvtop -v, and perhaps post some info from grep ^ /sys/class/drm/card?/device/*, in addition to lspci.

Hope this helps,
Steve

@Steve-Tech I can detect all my cards with nvtop 3.2.0, but usage is always 0%

[Steve-Tech]

@adrianboguszewski Hmm interesting, what kernel are you running and does it still happen with sudo?

[AbelKel]

@Steve-Tech thanks for the response. I did a clean install of the system because I felt that I had messed up somewhere when installing drivers. After compiling the latest commit, it now seems to be measuring GPU usage and memory consumption.

I was trying to get the power consumption and fan speed working but ran into a block. It seems like the sensors are not picking up anything from what I can see after running the sensors command:

Is there any way I can get the power and can speed working? I assumed temperature telemetry is not functional at the moment so I did not bother investigating that.

Also, I am on Ubuntu 24.10 and kernel 6.11.0-26-generic

Thanks again for the help!

[Steve-Tech]

@AbelKel for the sensors, I know exactly what's happening. nvtop is reading card, when it should be reading pkg. You could flip the order around here, or check that the value it read is non-zero: https://github.com/Syllo/nvtop/blob/master/src%2Fextract_gpuinfo_intel.c#L288-L297
I can also fix it this afternoon.

For the speed, could you post the output of tree /sys/class/drm/card?/ for me?
