When I try to install dev-libs/amdgpu-pro-opencl and choose ocl-icd (eselect opencl set ocl-icd), it's worse, the output of clinfo is just 1 line
Code:
Number of platforms                               0


Anyone can help so that I can use OpenCL on AMD GPU?

You have an old verion of llvm installed. Try with 5.0.1 version (is the last stable) of llvm and it's dependencies.

Also I had several problems with amdgpu-pro-opencl if I had USE="opencl" on mesa. So disabling opencl for mesa but otherwise enabling it globally had been a working solution for me.

I tried with llvm 5.0.1, but there is still output "NULL platform behavior" (.. No platform), only error disappears (=== CL_PROGRAM_BUILD_LOG ===
<unknown>:0:0: in function sum void (float addrspace(1)*, float addrspace(1)*, float addrspace(1)*): unsupported call to function get_local_size)

It is still 1 line output "Number of platforms 0"

Thanks for your replies. I will try with fresh new install. I'd prefer to opensource Mesa. Let's see what happens.

Using clover gets you practically nowhere. I didn't like it either, but using propietary OpenCL libraries seems to be the way at the moment. Mesa folks seem to be abandoned the whole clover project.

However who knows what we'll get in near future. The ROCm and Vulkan could offer something eventually.

So I try closed source amdgpu-pro-opencl. I installed mesa, amdgpu-pro-opencl.

+ If I choose ocl-icd ("eselect opencl set ocl-icd"), it fails to install clinfo. There are many errors in log, just remember "CL_DEVICE_TYPE_CUSTOM undeclared" first. Look in OpenCL headers:
there is define of CL_DEVICE_TYPE_CUSTOM in header of vendor/mesa and global
there's no define of CL_DEVICE_TYPE_CUSTOM in header of vendor/ocl-icd
+ If I choose mesa ("eselect opencl set mesa), it successes to install clinfo. But there is still the problem as my first post in this thread.

Could you give output of following cmd ?
Code:
find /usr/lib64/OpenCL -type f -iname '*.h' | xargs grep 'CL_DEVICE_TYPE_CUSTOM'


Or should we install amdapp (science overlay) ?
We are on holiday, I will come back in this weekend.
Thanks Zuccza and pcmaster again.

At some point to run OpenCL enabled programs I needed to set LD_LIBRARY_PATH to /opt/amdgpu/lib64.
So for example
Code:
LD_LIBRARY_PATH="/opt/amdgpu/lib64" darktable
to have OpenCL acceleration for my photo editing needs.

I'm getting mere 25Mh/s with my watercooled R9 Nano. :(
I'm using etherminer.
Although I started mining just becaue my PC was mostly idling. So better to make some use for it by mining eth.
I have another GPU at the attic. It's HD 7850. I don't think It'll be of any use. Especially because my PSU is only 600W max.

I use AMDGPU from kernel amd amdgpu-pro-opencl for opencl

Try to download and compile the clInfo available in https://github.com/janten/clutilities

make sure you are using at least 5.0.0 version of llvm and dependencies.

Currently, my /etc/env.d/03opencl is
Code:
LDPATH="/usr/lib32/OpenCL/vendors/mesa:/usr/lib64/OpenCL/vendors/mesa"
OPENCL_PROFILE="mesa"

i.e. I'm using open source Mesa with amdgpu-pro-opencl as we know using clover gets you practically nowhere.
I tried with amdgpu-pro::ROKO_ with some modification to install x11-drivers/amdgpu-pro-17.50.511655 (because x11-drivers/amdgpu-pro-17.40.492261 requires old kernel <=sys-kernel/gentoo-sources-4.11.0, https://warwick.ac.uk/fac/cross_fac/complexity/people/staff/delgenio/amdgpuprogentoo/). After
Code:
eselect opencl set amdgpu-pro
eselect opengl set amdgpu-pro

, it failed to start Plasma KDE, the screen blink frequently at log in prompt (no GUI). I used USB to boot again in Gentoo and see clinfo gave Segmentation fault.

So I decide to stay with Mesa and waiting for amdgpu-pro officially supported. If someone is using kernel 4.15.4 can install amdgpu-pro drivers, I'm glad if you can share the ebuild.

I use amdgpu (the open source one) as my gpu drivers. Then I have OpenCL libraries from amdgpu-pro-opencl from offical gentoo repository. So, no amdgpu-pro closed source drivers needed.
AND I also have enabled opencl USE -flag in /etc/portage/make.conf BUT I've disabled it for mesa. Since it seems to mess things up (as yo why it does/did, I have no clue, but there's no need to keep clover enabled anyway when you have OpenCL libraries from the closed source driver package).

[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for media-libs/mesa-17.3.2:
 U I

And since mesa has -opencl it means that Clover Gallium OpenCL state tracker is disabled and...
Code:
# eselect opencl list
Available OpenCL implementations:
  [1]   ocl-icd *
... I have only ocl-icd as an choice.

So basically. You'd probably just need to
run as root:
echo "media-libs/mesa -opencl" > /etc/portage/package.use/mesa-clover

Of course create needed /etc/portage/package.use/ -directory if it doesn't exist.
Then you should emerge -DNa @world. Just check that mesa is in there with change for disabling opencl. After that you should probably restart X so that mesa libraries get reloaded. Oh and unmerge amdgpu-pro drivers. Those SURELY mess things up with amdgpu-pro-opencl.

Anyway. That's what I have and it has been working from the first version of amdgpu-pro-opencl that appeared to Gentoo repository.

... oh and it's not up to Gentoo devs to support closed-source drivers offically. It's only if AMD is willing to support Gentoo (so far AMD only supports Ubuntu, SuSe, Redhat and maybe Fedora afaik). So you might be waiting for ever for that support. The open source drivers are supported in Gentoo.

I follow your guide and switch to only one ocl-icd. OpenCL headers still link to Mesa headers (that is deleted), so I create new soft-links. There are /usr/lib64/OpenCL/global/include/CL-{1.0,1.1,1.2,2.0,2.1}, I choose to link to CL-1.2 headers.
locate libOpenCL | xargs ls -l
Code:
lrwxrwxrwx 1 root root     38 Feb 20 16:41 /usr/lib32/libOpenCL.so -> OpenCL/vendors/mesa/libOpenCL.so.1.0.0
lrwxrwxrwx 1 root root     38 Feb 20 16:41 /usr/lib32/libOpenCL.so.1 -> OpenCL/vendors/mesa/libOpenCL.so.1.0.0
-rwxr-xr-x 1 root root    939 Feb 20 16:16 /usr/lib64/OpenCL/vendors/ocl-icd/libOpenCL.la

lrwxrwxrwx 1 root root     41 Feb 20 16:42 /usr/lib64/libOpenCL.so.1 -> OpenCL/vendors/ocl-icd/libOpenCL.so.1.0.0


I tried:
+ delete libOpenCL in lib32 (because Mesa directory is deleted)
+ link libOpenCL in lib32 to lib in lib64 of ocl-icd
both of them, it doesn't work. I compile some clinfo tools from github, it fails to get number of platforms (0). I can't install virtual/opencl because it requires USE opencl for media-libs/mesa.[/b]

You might need gentoo-gpu overlay.
I checked and have these packages from said overlay:
Code:
# find /var/db/pkg -type f -name repository -printf '%h::' -exec cat {} \; | sed 's|/var/db/pkg/||' | grep '::gentoo-gpu'
app-eselect/eselect-opengl-1.3.3_p1::gentoo-gpu
dev-libs/ocl-icd-2.2.11-r1::gentoo-gpu

I lost opengl profile after used eselect-opengl::gentoo-gpu
Code:
eselect opengl list
!!! Error: Invalid symbolic links: OpenGL implementation "" symbolic links are missing.
Available OpenGL implementations:
  (none found)
exiting


While using eselect-opengl from portage
Code:
eselect opengl list
Available OpenGL implementations:
  [1]   xorg-x11


Should we use eselect-opengl::gentoo-gpu? I we should, so what we need to reinstall related with OpenGL?

Sorry my bad. :( In a hurry I read opengl as opencl.
Interestingly I also get none from the eselect output but still have direct rendering enabled.
Better to remove eselect-opengl::gentoo-gpu.

Now... back to OpenCL.
It seems that I have app-eselect/eselect-opencl-1.1.0-r6::gamarouns installed. That might help along with dev-libs/ocl-icd-2.2.11-r1::gentoo-gpu.

So. Now you have
  • removed amdgpu-pro
  • recompiled mesa with -opencl
  • your gpu drivers are amdgpu
  • you have installed opencl libraries by emerging amdgpu-pro-opencl
... right?

After that see if you can select some OpenCL implementation using 'eselect opencl'.

I have

removed amdgpu-pro
recompiled mesa with -opencl
gpu drivers are amdgpu (if it means that I have to config kernel following https://wiki.gentoo.org/wiki/AMDGPU, so Yes)
installed opencl libraries by emerging amdgpu-pro-opencl

I can eselect ocl-icd now, but clinfo still doesn't return platform info.

Do we need to link library to /opt/amdgpu (that is belong to amdgpu-pro-opencl) ? I see that /usr/lib64/libdrm_amdgpu.so.1.0.0 and /opt/amdgpu/lib64/libdrm_amdgpu.so.1.0.0 are different.

What's the contents of your /etc/OpenCL/vendors/ocl-icd.icd?
Also what you get if you run
Code:
LD_LIBRARY_PATH="/opt/amdgpu/lib64" clinfo
?
