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....

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"

@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.
