Did brief battle again tonight. If I add USE=opencl mandelbulber fails to build because cl.hpp is a dangling symlink. So after looking through this thread a bit more, I installed opencl-clhpp from the science overlay. I know there is a fixed version in the zucca overlay, but it's not in stock layman and I didn't feel like looking up the pointer to it - yet. Anyway, the stock installation from science overlay drops the files in /usr/include/CL - not where they're being looked for. So I added a few symlinks:
| Code: | # ls -l /usr/include/CL
total 0
lrwxrwxrwx 1 root root 15 Mar 19 20:28 cl2.hpp -> /usr/CL/cl2.hpp
lrwxrwxrwx 1 root root 49 Mar 17 22:16 cl_egl.h -> //usr/lib64/OpenCL/global/include/CL-1.2/cl_egl.h
lrwxrwxrwx 1 root root 49 Mar 17 22:16 cl_ext.h -> //usr/lib64/OpenCL/global/include/CL-1.2/cl_ext.h
lrwxrwxrwx 1 root root 52 Mar 17 22:16 cl_gl_ext.h -> //usr/lib64/OpenCL/global/include/CL-1.2/cl_gl_ext.h
lrwxrwxrwx 1 root root 48 Mar 17 22:16 cl_gl.h -> //usr/lib64/OpenCL/global/include/CL-1.2/cl_gl.h
lrwxrwxrwx 1 root root 45 Mar 17 22:16 cl.h -> //usr/lib64/OpenCL/global/include/CL-1.2/cl.h
lrwxrwxrwx 1 root root 14 Mar 19 20:28 cl.hpp -> /usr/CL/cl.hpp
lrwxrwxrwx 1 root root 43 Feb 25 19:56 cl.hpp-orig -> ../../lib64/OpenCL/global/include/CL/cl.hpp
lrwxrwxrwx 1 root root 54 Mar 17 22:16 cl_platform.h -> //usr/lib64/OpenCL/global/include/CL-1.2/cl_platform.h
lrwxrwxrwx 1 root root 49 Mar 17 22:16 opencl.h -> //usr/lib64/OpenCL/global/include/CL-1.2/opencl.h |
With this, mandelbulber builds. But as soon as I go into preferences and try to enable OpenCL, it segfaults. Soon I'll look a bit harder and get the zucca version of opencl-clhpp and see if that's any better. Enough fiddling for tonight. I don't stay up as late as I used to.

It's not any better than your current manual symlinking. :( It only has -DCMAKE_INSTALL_PREFIX adjusted correctly so that the files get installed into the right directory.

Are you able to run mandelbulber with OpenCL on your setup? I don't think of eselect stuff as really being "in the path" more setting the paths for other packages. With that, the big difference I see between us is that you're getting ocl-icd from gentoo-gpu and I'm getting it from the base.

Yes. I can use OpenCL with every program I have installed which uses it.

Not yet. I have exactly the same problem with fresh 18.10
Previously I tried 17.XX, they *almost* work, but produced artifacts (looking much alike a corrupted memory) on my Cape Verde GCN 1.0 card with darktable and all other apps I tried.
After the upgrade I got
| Code: | | Number of platforms 0 |
no matter what I tried...
Everything looks just fine but doesn't work... |

I'm in the middle of a huge rebuild process (and qt5 causing many blockers). After I've adjusted all the USE -flags and rebuilt many packages I'll see if I stuble upon any problems mentioned in this trhead and then try to create a solution for it.

I'm bored so I gave this a try. Getting the same 0 platforms thing.
Sequence of events so far:
- Rebuilt my system with USE=opencl globally (no amdgpu-pro at this point)
- Verified that clinfo detects my GPU (a RX550)
- Verified that clover runs exactly zero interesting opencl programs
- Installed amdgpu-pro-opencl-17.50-511655 (after doing a bunch of dodgy stuff I found in a web search[1] to obtain the distfile because it's been hidden from their site)
- eselect opencl set ocl-icd, verified /usr/include/CL/ is in order
- clinfo now returns nothing.
But: running it in strace, I can see it looking for amdoclsc64.so. The amdgpu-pro package didn't install that, and it doesn't seem to be present inside any of the .deb files within. Maybe that's the source of everyone's problem here?
| [1]: | cd $DISTDIR
wget https://www2.ati.com/drivers/linux/ubuntu/amdgpu-pro-17.50-511655.tar.xz --referer http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-for-Linux-Release-Notes.aspx |

18.10 doesn't have this file either. However they've changed some names. Here's my /opt/amdgpu with amdgpu-pro-opencl-18.10 installed:
| Code: | [kanyck: ~]$ tree /opt/amdgpu/
/opt/amdgpu/
├── lib64
│ ├── libamdocl64.so
│ ├── libdrm_amdgpu.so.1 -> libdrm_amdgpu.so.1.0.0
│ └── libdrm_amdgpu.so.1.0.0
└── share
└── libdrm
└── amdgpu.ids
|
BTW I wander if there's a place to file bugs for amdgpu-pro. I tried few usual places, like kernel.org and freedesktop's bugzillas with no apparent success -- they all were ignored for months. On phoronix bridgman encouraged people to file bugs but never discovered where to, even being asked explicitly. And very few chances are to get help on phoronix, too. Meanwhile there are some things, like env vars, to be set to get apps working. Setting the following moved me one step further when I attempted this issue last time few months ago:
| Code: | export GPU_FORCE_64BIT_PTR=1
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=90
export GPU_SINGLE_ALLOC_PERCENT=90
export GPU_MAX_HEAP_SIZE=90 |
I've found this on forums, but couldn't trace where those came from, neither if there are some other important things to get it working... |

I haven't had time to fiddle with this for quite a while, though someday I'll get back to it. In the meantime, I saw this on Phoronix the other day, which seems relevant to this discussion. The comments are worth checking out, too.

Has anybody tried the getting OpenCL working with the 18.20 drivers yet? I modified an ebuild to fetch the new package, but I can't get it working. I get "Number of platforms 0" when I run clinfo.

With the ebuild added to the in the main repo on the 24th of Jun, openCL seems to work using Darktable's openCL test and can be enabled from it's options. I built mesa without openCL support so you may need to do that. |

Do you disable the opencl use-flag globally, or just for Mesa? I have a problem where Blender/Darktable/etc are pulling in OpenCL on Mesa, since they have enabled opencl flags, even though I've disabled it specifically for Mesa.

Fascinating...
A month or two back I installed amd-gpupro-opencl-17.xxxxx. It responded to clinfo OK, but I wasn't actually able to do anything with it. I installed Mandelbulber just to try it out, and whenever I tried enabling opencl, it crashed.
More recently I recompiled my whole system with gcc-7.3, and amd-gpupro-opencl failed to build, but since it never worked in the first place, I never got around to debugging it.
Seeing this, I decided to try amd-gpupro-opencl-18.xxxxx. It compiled OK, and it works! Picking one of their examples, rendering on just the CPU takes about 9.3 seconds. Enabling OpenCL, the first render takes 1.7 seconds, with some of that time spent "compiling OpenCL programs". Subsequent renderings take 0.6 seconds.

What does clinfo tell you now?

I have -opencl specifically on Mesa; after amdgpu-pro-opencl is installed darktable shoudn't try and pull it in from Mesa. |

Hm, mine does. It specifically needs Mesa with opencl flag, according to portage. But perhaps it wasn't because of darktable but because I have the global opencl use flag enabled.

Just checked, and I don't have opencl in my make.conf. It is in my package.use/darktable though. |

That's weird. I just disabled my global opencl use flag, and enabled it only for Blender and Darktable. But when running "emerge -uDN world" I still get:
| Code: | The following USE changes are necessary to proceed:

so it seems Darktable is still pulling it in.
It doesn't seem than opencl or anything else depends on amdgpu-pro-opencl yet.

Just a heads up clinfo ebuilds will not build unless mesa is built with opencl support. I've submitted a bug for this
https://bugs.gentoo.org/660572
I've managed to install both versions of amdgpu-pro-opencl to test if ether version would function with the big picture goal to get ethminer functional on gentoo using RX480/580 graphics cards without needing the entire amdgpu-pro stack however both clinfo and ethminer reply with No OpenCL platforms found with mesa built with or without opencl support
The 17.50 ebuild for amdgpu-pro-opencl was updated to EAPI-7 but the ebuild itself was not updated to reflect eapi changes with dolib requiring a change to dolib.so and addressing that minor issue the 17.50 ebuild worked perfectly fine.
| Code: | src_install() {
into "/opt/amdgpu"
dolib.so opt/${SUPER_PN}/lib/x86_64-linux-gnu/*
dolib.so opt/amdgpu/lib/x86_64-linux-gnu/*
insinto "/opt/amdgpu"
doins -r opt/amdgpu/share
insinto /etc/OpenCL/vendors/
echo "/opt/amdgpu/$(get_libdir)/libamdocl64.so" > "${SUPER_PN}.icd" || die "Failed to generate ICD file"
doins "${SUPER_PN}.icd"
} |
amdgpu driver's all loaded and eselect opencl is set but still 0 devices found by ethminer or clinfo. I do currently have amdgpu kernel driver built as a module with the firmware being loaded from userland of that matters. The amdgpu graphics cards will all be secondary display devices to the intel igpu with this configuration.
If anyone has a suggestion i'm certainly interested.
| Code: | vargur ~ # clinfo
Number of platforms 0 |

▒ 19:13:20|ethminer| No OpenCL platforms found |
| Code: | vargur ~ # eselect opencl list
Available OpenCL implementations:
[1] mesa
[2] ocl-icd * |
One possible discrepancy with the above eselect entries i discovered is there is an icd file added for amdgpu-pro.icd but that listing is not available in eselect opencl. I dont know if this is an eselect config bug with the relevant package that could directly be responsible for opencl compute detection not functioning.

For what it's worth, all I had to do to get working opencl support was:
* use ~amd64
* use a recent kernel (4.17 is what I'm using)
* use the amdgpu driver
* set the "opencl" use flag globally
* emerge dev-libs/amdgpu-pro-opencl (currently version 18.20.606296)
* make sure "ocl-icd" is selcted in "eselect opencl list"
I'm not using any overlays.
dev-util/clinfo (again, not from any overlays) shows 1 platform named "AMD Accelerated Parallel Processing"
I suspect that there's a lot of cruft left over on systems from before it was this easy as well as some broken stuff being used from overlays. Please try to stick to what's in Gentoo without overlays (if you do find something great from overlay, get it into Gentoo), try to report bugs (thanks for reporting the clinfo one, ali3nx!) and submit PRs to fix things.
