Yes, in general OpenCL for current AMD GPUs works with the open

I don't know anything about this topic, but for such a issue the first
thing I do is to search inside packages contents from this page:
https://www.debian.org/distrib/packages
I did that, but there are quite some assumptions implied by this
approach, mostly that a file of that particular name is *required* for
nay OpenCL implementation with this hardware -- and that is something I
hesitated to believe in :-)
In you case, the results might indicate that your GPU is not supported
by Debian ?
https://packages.debian.org/search?searchon=contents&keywords=mesa3d.bc&mode=path&suite=stable&arch=any
I'll try to install the Ubunto packages later as this may require some
Always this same typo of mine ^
This is either the reason for, or the result of, me not liking Ubuntu ;-)
serious cleanup first
Well, I did some of that cleanup (essentially it was removing the
relevant mesa packages, purging the configuration (removing the entries
in the /etc/OpenCL/vendors directory) and leaving the one from the AMD
packages behind.
The results were most exciting:
- clinfo had no error messages any more
- I could start OpenCL Primegrid tasks via boinc
Definitely a step forward.
Unfortunately there are more steps ahead, as any Primegrid task using
the GPU fails with an error:
opencl error: CL_OUT_OF_HOST_MEMORY
As I have no other real OpenCL workload I can try with any reliability,
and I also have lots of host memory available, I suspect this due to the
messy state of the software or its installation. And, as the
installation has definitely not been done in any documented manner, I
would not be surprised if that's the problem.
So, the challenge remains to find a way that reliably provides a working
system, but it seems as though Mesa is not going to be the way towards
this solution.
Thanks for all your input so far!
Arno
