Hi all,
Do you know how to activate/install the OpenCL 1.2 for the AMD Tahiti PRO [Radeon HD 7950/8950 OEM / R9 280]?
I've spent a lot of time going through the forums without finding a solution besides downgrading to ubuntu 14.04 or 12.02 where i could install the proprietary driver 15.9.
Thanks in advance for your support!
Cheers
Hi Harvey, the reason im asking support is that ive already spent endless hours searching without success (incl Ubuntu keywords yes)...
Do you have any suggestions, links to sort this out?
Cheers
Do you already have opencl installed, but wish to downgrade the package or are you looking for OpenCL support?
If the latter, have you tried:
sudo apt install intel-opencl-icd ocl-icd-opencl-dev
Hi Aravisian, thanks for the quick response.
I know my card supports OpenCL 1.2 however when i run clinfo it states that the device is running OpenCL 1.1

Not sure what to do to install openCL 1.2. I read that via an SDK it is possble but was unable to find a solution.. The output is after i ran your command.
Cheers and thanks in advance for the support!
Have you tried the install option I gave above?
If that is not working, try this .deb package:
http://archive.ubuntu.com/ubuntu/pool/main/o/ocl-icd/ocl-icd-libopencl1_2.2.11-1ubuntu1_amd64.deb
If that says that the Same Version is already installed, then you do have opencl1.2 and 1.3
It means that due to your hardware, 1.1 is what is being used.
Hi there,
Yes i tried the commanded you provided above and then i shared the output. As it states it seems version OpenCl1.1 is being used though 2.2 is installed. I know my gpu can handle up to OpenCL1.2 (not possible to use >=2.0) thus my question : how can i install OpenCL1.2?
When i tried installing the deb it mentions that it is already installed:
Cheers
It is already installed.
If the software is installed, why is'nt my hardware using it then?
Below are the specs of my gpu where it clearly states OpenCL 1.2 thus my hardware should be able to use it:
Where is it mentioned that OpenCL 1.2 is installed i only can see 2.1
Cheers
The .deb package I linked above contains it. If you need, you can double check this.
Save and extract the file. Then extract Control.
Open the Control file - Look to the Provides line:

Description: Generic OpenCL ICD Loader
OpenCL (Open Computing Language) is a multivendor open standard for
general-purpose parallel programming of heterogeneous systems that include
CPUs, GPUs and other processors.
.
This package contains an installable client driver loader (ICD Loader)
library that can be used to load any (free or non-free) installable client
driver (ICD) for OpenCL. It acts as a demultiplexer so several ICD can
be installed and used together.
As to why your hardware is not using it... I do not know.
But I am looking for information...
What vulkan version are you running?
Also, can you please post the output of
cat /proc/cpuinfo | grep sse4_2
Vulkan Instance Version: 1.2.131
Vulkan version 1.1.73
When i try
cat /proc/cpuinfo | grep sse4_2
Nothing is shown..
My CPU is "Intel(R) Core(TM)2 Quad CPU Q9650 @ 3.00GHz
That is odd...
Did you copy and paste it into terminal?
Well, then...

This may be your answer. The minimum requirement for OpenCL on a CPU is SSE 4.2.
From your output above:
sse4_1
Seem i found an interesting article
Funny they mention not supported "anymore" + crossed!? Any idea why? 
I am not sure. I had seen that one and a few others that also mentioned AMD dropping support as well. But I had not really read too deeply since you are, at least, using 1.1
