OpenCL on 14.12 Omega driver crack's OpenCL on linux

Hi, I have a amd kabini laptop, it's on AMD A6-5200, there is Radeon HD8400 and Radeon HD8570,

Some time ago I can use opencl on my laptop for rendering in blender or using handbrake, libroffice, it can be done for all cpu and gpu together (4 Jaguar cores+Radeon HD8400+Radeon HD8570), but now there is Catalyst 14.12 omega driver and there is some problem.

So, CPU can use only OpenCL 1.2, and Radeon HD8400 can use OpenCL 2.0 with new driver. HD8570 is not active now(UMA graphics in bios), but it can use only OpenCL 1.2 too. So, now with this driver all applications that can use OpenCL can't use it, Blender, Libroffice does'nt show anyone OpenCL combute device in settings, same for handbrake in init logs from it.

Hi,

Let us take it one application at a time. Libreofiice calc is tested to work with Omega driver. So I am not sure what is happening at your end.

Which version of LibreOffice do you have?

Regards,

Ravi

hi, Libreoffice version is 4.4.1.2, from official ppa, ubuntu 14.04.2

As you mentioned, at some earlier time, you were able to use opencl for those applications. What was the catalyst driver version? Is that driver still working fine for your system?

I' don't remember from which driver version opencl become avaiable for software like handbreake and blender, but previos version, catalyst 14.9 really has working opencl. UPD: It become working exactly in 14.9, and I can run blender of all platforms together(igpu+dgpu+cpu) with opencl.

It was on ubuntu 14.04, but now some libs which needed for installing catalyst 14.9 are not avaiable, so I can't install it again. I can't build .deb files, and if I install it manualy, the Xorg will not start

New version, fglrx 15.20(from ubuntu 14.04 repos) still can't use opencl.

I am splitting Danil's post since it did both continue this thread and ask a new unrelated question. Below is the part of Danil's message pertinent to this discussion. The Blender question is here: When will Blender build be available with performance improvements?

---

I can't install it now, becouse ubuntu 14.04.2 uses Xorg 1.16.1, and fglrx14.301 can work only with 1.15, but I install ubuntu 14.04 and install on it fglrx 14.301. OpenCL is works, but ubuntu want's to update fglrx packages to 15.20(update center will do it on next upgrade).

It's something strange, after I install 14.9, opencl works(on 14.04 with 1.15.1 Xorg before upgrading), then Ubuntu updates some packages of fglrx, and give an error during installation, then i run sudo apt-get purge fglrx*, and run system with mesa, after it I try to install xserver-xorg-lts-utopic and kernel from utopic, and install 14.9 catalyst from .deb packages, system can't load X-server, then I purge 14.9 and install 15.200 fglrx, and it can run OpenCL in blender now!  With OpenCL 2.0 on Radeon HD8400(Radeon R3), and the same in my main Ubuntu OS 14.04.2(all previos was on testing OS 14.04) and fglrx15.200, so now, I don't know how, but OpenCL works for Blender everywhere, but... when I try to run OpenCL by CPU in blender it's crushes with "Copying BVH to device".

And when I run OpenCL test in libreoffice it's gives an errors for all tests.

About blender:   is the OpenCL device list depends on Blender or on OpenCL drivers? There are entries: "AMD A6-5200" "Kalindi" "Hainan" and "AMD A6-5200+Kalindi+Hainan" and I cannot use only one of GPU with CPU or two GPU's without CPU.

Good to hear that fglrx 15.200 is working for you now. As you mentioned, you're able to access the OpenCL from blender (and other apps) but crashes when using it. Did you try any other OpenCL program (say any APP SDK OpenCL sample) to see whether OpenCL is properly working or not?  If samples run fine, then OpenCL setup is okay. Then there may be some other issues for the crashing. Please check and be sure.

I'm not sure about your blender question. I guess, blender forum may be more appropriate for this type of queries or someone more knowledgeable about blender may comment about it.

OpenCL is working for me in blender now, with ubuntu 14.04.2(kernel and xorg form 14.10), and I can use it in blender for rendering, and in handbrake. But when I choose in blender opencl on cpu(choose AMD A6-5200 OpenCL device or together with other opencl devices) it's crushes. With 14.30 all was good.

If I try to test OpenCL in LibreOffice, it's gives errors in all colums.

Strange, that now I have install a new 14.04.2 ubuntu from 0 to my laptop, with fglrx15.200, and In this OS OpenCL doesn't works(blender doesn't show opencl devices, and handbrake too). But in my main OS, it's still works.

About fglrx-why there is 15.200 on ubuntu repositories now, but only 14.12 on amd website?

Abut opencl-I can give you a clinfo information.

Regarding the catalyst, I really don't know why the mismatch is. I've asked the concerned team for more information. Once I get any reply, I'll share with you.

However, as I've been told, catalysts from AMD site are preferred one, if available. Did you ever try this package Desktop ?

Another fact which I came to know that Ubuntu 14.04.2 comes with an open source driver also known as Radeon driver. That open source driver does not have OpenCL.

On that page latest version is 14.12, and in ubuntu repos, latest fglrx package is 15.200.

It's not stock opensource driver, installed in ubuntu by default, it's fglrx package from stock repos, and OpenCL is working for it(in Blender and Handbrake, at least)

I don't know, will it work on ubuntu 14.04.2 with fglrx 14.501 from AMD website(catalyst 14.12), but some games like The Witcher 2 had some bugs on that driver, and I can't use OpenCL on it before.
