No VRAM usage on TONGA ( R9 380(x) ) (amdgpu)

[spacekookie]

When I use radeontop with my HD 7770 (GNC 1.0) it can detect the VRAM usage. When I do it on my R9 380X it tells me "Kernel too old for vram" and doesn't.

I am running Ubuntu 16.04 on Kernel 4.7 for both scenarios. Anything you can do about it?

Your newer card uses the amdgpu driver, not radeon. Radeontop has no support for amdgpu, I'm not sure if amdgpu even exposes a VRAM query, and even if it did, I have no such cards to test with.

In short: patches welcome, but not sure it's possible ATM.

Confirmed on Fiji and Polaris.

I did some investigation into this and it seems that there is a way to get the VRAM usage via Gallium:

GALLIUM_HUD="fps,VRAM-usage,GPU-load" glxgears

I was also able to run Steam games with this by appending it to the run command

GALLIUM_HUD="fps,VRAM-usage,GPU-load" %command%

Long story short: amdgpu exposees VRAM usage :) So if Gallium3D can do it, I would hope so can radeontop

@spacekookie looking into it.

I have it working on Tonga here, pull request incoming.

[spacekookie]

Hurray :) Awesome! Looking forward to getting the updated version

[vedranmiletic]

@spacekookie try #39.

Fixed in git.

@vedranmiletic

I tested it out. It builds but it doesn't seem to be able to pick up vram usage for me (link).

My system is Ubuntu 16.04 with Kernel 4.8-rc1 and I own an R9 380X (which is Tonga). Do you know if there is something else I need to enable to make this work? :/

[vedranmiletic]

Did you enable the amdgpu option in the Makefile?

[spacekookie]

Ah nvm...I didn't lok at the Makefile. It works now. Awesome :) <3 Thanks
