AMDGPU - anyone tried?

As of sunday LKML announcement  , the  Kernel has been fitted with the AMDGPU drivers .  What's up with that regarding Archlinux? Should I rather look in the dev mailing group?

Kind Regards. P

My guess would be that it will be on Arch the moment it is included in the kernel.

Re: AMDGPU - anyone tried?

the AMDGPU driver is part of the linux 4.2 kernel. I think we will also need some xorg stuff like xf86-video-amdgpu or something.

xf86-video-amdgpu was created for old distributions (in particular RHEL) that ship with versions of X which don't have the modesetting driver built-in. Arch isn't one of those distros, so xf86-video-amdgpu won't be necessary. Aside from kernel 4.2, the only thing needed is some firmware that isn't yet in the linux-firmware package, for now it's available here.

Re: AMDGPU - anyone tried?

Thanks for your responses. I've decided to give it a spin and compile my own kernel with the k10-ck patchset, along with amdgpu. Since it's my first compilation that is this huge, I would sincerely appreciate any thoughts from more experienced users before I bust the open door down. I've already gotten the sources via ABS, along with the patches - before I start doing stuff on my own, I'd be happy to learn something from you guys. Naturally, I'll report back should it interest anynone.

Will A8-7100 benifit from it?

No GPU will "benefit" from it. It's a new driver for GPUs that aren't supported at all yet - Tonga, Topaz, Carrizo, Fiji. The A8-7100 is Kaveri, so it will not use this new amdgpu driver.

Exactly as Gusar said - phoronix states that there's an option to enable amdgpu for a Sea Islands chip which I happen to have.

Take a look at the linux-ck pkgbuild in the aur. It should help you on your way.

Re: AMDGPU - anyone tried?

Yes, but support for Sea Islands/CIK is only in the driver because the developers used it while creating the driver. It isn't meant to be used, it's not officially supported, it doesn't bring any benefits to CIK cards. To quote an AMD developer himself, from here:

I don't expect any difference in performance and there's no reason to think one kernel driver is better than the other. They are just meant to support different chips on the kernel side.

CIK cards are already supported by the radeon driver, and distros will *not* enable CIK support in the amdgpu driver because that would create a conflict about which driver to load.

mbates' Kaveri is actually from the CIK family, so he could use amdgpu in theory, but as the quote says, it doesn't bring anything. No reason to use amdgpu if you don't have a Volcanic Islands (Tonga, Topaz, Carrizo) or Fiji GPU. Actually, Fiji support isn't there yet, it will come in a future kernel.
