[SOLVED]AMDGPU + Conky: Getting gpu load and frequencies

marcelo1401 · 2017-02-24 23:42:31

Hello,

I'm trying to get my gpu load and frequencies to display on Conky. I already found one command that gives me this info but it depends on the usage of sudo, which stops it from working on conky, at least I can't do it. This is the command

sudo cat /sys/kernel/debug/dri/64/amdgpu_pm_info

I do know how to combine it with grep and cut to get the info I need the problem being the usage of sudo. Is there any other command or a way to use sudo with conky?

Thanks in advance.

Either change the permissions on the file so that it can be read by a non-root user, or add an entry to sudoers so you can run the command without a password.

I might do that but is there any other way of doing this? Is there a program/command that can give this info without having to be root?

If you are using open source drivers there may be.

mesa can provide a HUD for gallium drivers and also supply the data to lm-sensors .
currently only mesa-git from LordHeavy's mesa-git repo is build with those options.

Do you know when this will enter mesa stable version? I might end up using slithery's solution and waiting for this to be merged to mesa stable.

These are the permissions on the file that has the info I want:

-r--r--r-- 1 root root 0 Feb 26 15:59 amdgpu_pm_info

Considering that all users have read permissions, shouldn't I be able to read it without having to be root? What permissions would I need to set to be able to do what I need? Do I need to change the owner/group?

Tried changing the owner to myself without any luck, still need to be root. Also tried looking at /sys/class/hwmon/hwmon3 (which I found out refers to my gpu) but didn't find a file that gives the load. My question is: isn't this the directory lm_sensors uses to get the info it displays? If so, considering that lm_sensors doens't show gpu load, I shouldn't find the info I want here, right?

Lone_Wolf · 2017-02-27 11:38:15

/sys/kernel/debug/ is a pseudo-filesystem that is only accessible by root afaik.

I have not seen any posts from people using those new mesa options, i suggest you try them to see if they can provide what you need.
If they do, there's a clear use case for them and you could create a feature request to get them in arch stable mesa.

Lone_Wolf do you know how to enable the HUD? I think I installed the right package. Followed this link mesa-git - latest videodrivers & issues. Can't find info on how to enable the HUD.

Looks like you configure/enable the gallium-hud through environment variables ( 5 of them) ,

check https://www.mesa3d.org/envvars.html , search for GALLIUM_HUD

marcelo1401 · 2017-02-27 14:24:14

Yup, thanks. Found out allready how to enable it already. Now just have to find how to integrate it with conky

marcelo1401 · 2017-02-27 21:47:03

As I said, I already found out how to have it display what I want over a game. The only thing I need now is how to supply this info to lm_sensors. Any idea? Been searching for a solution with no success. Btw, thanks for your help so far.

HiImTye · 2017-02-27 23:07:06

have you run the sensors-detect part of lm_sensors?

marcelo1401 · 2017-02-28 00:09:44

Yes. Still no luck

Lone_Wolf · 2017-02-28 12:00:53

I've looked into mesa sourcecode and it seems --enable-lmsensors allows the gallium HUD to use stuff already exposed by libsensors library instead of the other way around.

Sorry, no idea how to continue.

marcelo1401 · 2017-02-28 14:22:27

Couldn't find an answer either. But the HUD serves my purpose even better so I'll mark this as solved (kind of) and if I happen to find an answer I'll post it somewhere in the forums. I'd still like to have at least frequencies show up on Conky. Btw, the HUD actually works on regular mesa from extra/multilib.

As you can see I'm running a stable version of mesa and I tried setting the environment variable to show gpu load graph and it actually worked. It may be because of residual bits from LH's mesa-git but I dont think so. There's no need to ask for it to be merged to mesa stable then. You can see here that there's no git packages relating to mesa on my system (at least I think this lists them all)

[marcelo@archlinux ~]$ pacman -Q | grep mesa
lib32-mesa 17.0.0-2
lib32-mesa-libgl 17.0.0-2
mesa 17.0.0-2
mesa-demos 8.3.0-2
mesa-libgl 17.0.0-2

Thanks for all you guys' help

NOTE: If you think I should mark this as anything else than solved please let me know.

I checked and it does seem like gallium_hud functionality is enabled by default in mesa.

Those 2 configure options just add extra features.

Edit :
you found a way to get what you want, even if it isn't through conky.
Solved does seem appropriate.
