The AMDGPU Info/News Thread



Hey, I found a way to change clockspeed by changing "pstate" of gpu in /sys/kernel/debug/dri/0 ( found at ) but performance isn't good enough for me ~80 fps in CS:GO on fedora with mesa+gallium9+PowerPlay+LLVM 3.9+ ...
Also I've tried to use gpu passthrou and fps is low there as well, unlike native win10 where i get ~140+ fps all the time. :frowning:


Keep in mind they only just implemented full opengl support. There's been no real extra optimisation yet.


Mhm, yeah but "scheduler" (power managment) is kinda problematic with keeping clocks under 50% when playing game tho :confused:


Update on the TrueOS thing: I installed it and the desktop doesn't seem to lag the way it did before, but the resolution is kind of messed up and I dont have any display settings (they were there in the last version) . Ill play around with it some more today though





People still think the Pro Duo never came out :T
like really?


More hires for the GPU stack...


Does anyone have a good source of the flags and switches exposed to Linux for getting and setting amdgpu parameters?


gentoo wiki?


It doesn't list any.


Not much, but the only useful link that I have are is


Does anyone has played around with the 4.12 rc1?

i compiled it on my machine today.

but i got 2 errors:

Hey, can anyone test CS:GO on ubuntu with amdgpu and relive drivers too? I've tried running arch and amdgpu with mesa+gallium9 in wine, ain't playable, native: ain't playable either getting ~60% of gpu performance with random clock reduced to 700MHz ... (rx460 here). thanks


you needl ike the bleedingest edge mesa drivers ever. Once you've got those.. its.. I just don't even.
Big changes on the horizon. Big. I'm excited about the future of these drivers and the kernel. Things are happening!


Phoronix did some testing with the free driver and AMD's closed source. Seems like AMD only optimize for unigine...

CS:GO runs fine on the open driver.

At 1080p, the Counter-Strike: Global Offensive performance is very close between these two AMD OpenGL drivers, but at 4K, the open-source RadeonSI Gallium3D driver is doing much better. It will be interesting to see if this changes with the summer roll-out of CS:GO on Source 2.

As Wendell says, this is with Linux kernel 4.12 and Mesa 17.2-dev that is fresh straight from the Git repo. Doesn't get any more bleeding edge than that.


Mesa Dev 17.2 makes the FOSS AMD drivers just 8 - 15% behind the binary Nvidia and there is some more work going into tweaking the threading to reduce this gap.

We nearly made it boys! (and grils)


SteamOS has left the proprietary AMDGPU-PRO for the open source driver and Mesa.

First, we have rebased our kernel changes on top of the latest 4.11 Linux kernel. We have updated all the graphics drivers. This update also switches SteamOS from the proprietary AMDGPU-PRO driver to the open source mesa driver.


Can you post link for their git, am in trouble trying to find it tho .. :frowning:


Can anyone post links to latest mesa17.2-dev for now I guess? I can't find sources on Google :confused: thanks.


Theres stuff in the top post.
