Although I would really like full OpenCL support in Mesa for AMDGPU.

Yeah, thats something they still need to work on. Although, if you're on arch, you can get the opencl package from amdgpu-pro as a separate package. Though I haven't tested it yet
Yeah I tried that but had some issues. Didn't really feel like trying very hard though lol. I'm not running an Arch machine for anything else than 3D printing for the moment. I need to get back into Arch a bit, just have to set priorities, not everything is always possible schedule wise.
Yes, I would really like full OpenCL too. A while ago I tried the opencl packages that were available, but never could get something like folding@home to work. I think they are specifically looking for the proprietary driver though. I've gotten some opencl stuff to work, some example code would run and clinfo etc did display support.
I don't run linux much on my main rig as my Powercolor GPU tends to hard lock Linux. Firmware related it seems like, only way to get around it seems to be to unplug it.
How has an intel iGPU and AMD card using amdgpu? I know this affects RX 480 and most cards using amdgpu. I think is also affects any cards that are capable of using wayland
Can you check this, test and comment/provide details on the bug reports if your also affected? @wendell @dot404

Does anyone knows how to make sclk ramp up faster and stay at higher freq. is there like scheduler for gpu clocks or some settings for PowerPlay where i can set how it behaves.
Reason = core clock doesnt go too far ~1100 MHz and then go back to ~400 MHz while playing cs go, and when it's high am getting good fps but when it drops for no reason i get stuck at 40-50 fps .... doesn't matter which graph settings i use ingame.
Sorry @sinisa94, I dont know a lot about reclocking in amdgpu. Although an incosistent clockspeed might be the reason for my inconsistent framerate in borderlands (resulting in a really shitty experience). Is there a way to display the current clockspeed?
On another note, there is a new stable release of TrueOS, so I am going to see if amdgpu finally works for me
Hey, I found a way to change clockspeed by changing "pstate" of gpu in /sys/kernel/debug/dri/0 ( found at https://github.com/giuliojiang/AMD-Linux-Power-Management ) 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. 
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 
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 http://www.mikejonesey.co.uk/linux/amdgpu-linux-driver-parameters

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
