Is there OpenCL support using Mesa Drivers?

blackout · 2015-04-05 19:24:57

I have an AMD A10-7850K and would like to use OpenCL in Libreoffice and also other applications.

What I have found in Libreoffice Calculator if I go to tools>options>OpenCL
everything is fine
in the subsection LibreOffice Calc>Formula

I can set Custom (use OpenCL) but after closing it turns back to default.
If i click Details and run the test all tests fail.

According to http://dri.freedesktop.org/wiki/GalliumCompute/
SeaIsland chips like mine should be supported.

According to the wiki
https://wiki.archlinux.org/index.php/Op … Gallium.29
mesa is not built with opencl (2004)
but when I look into the recent PKGBUILD i have opencl enabled

  ./configure --prefix=/usr \
    --sysconfdir=/etc \
    --with-dri-driverdir=/usr/lib/xorg/modules/dri \
    --with-gallium-drivers=r300,r600,radeonsi,nouveau,svga,swrast \
    --with-dri-drivers=i915,i965,r200,radeon,nouveau,swrast \
    --with-egl-platforms=x11,drm,wayland \
    --enable-llvm-shared-libs \
    --enable-egl \
    --enable-gbm \
    --enable-gallium-llvm \
    --enable-shared-glapi \
    --enable-glx \
    --enable-glx-tls \
    --enable-dri \
    --enable-osmesa \
    --enable-gles1 \
    --enable-gles2 \
    --enable-texture-float \
    --enable-xa \
    --enable-vdpau \
    --enable-omx \
    --enable-nine \
   [b] --enable-opencl --enable-opencl-icd \[/b]
    --with-clang-libdir=/usr/lib

If i execute

$ ls /etc/OpenCL/vendors

i get mesa.icd

if I run any opencl tests from
http://dri.freedesktop.org/wiki/Gallium … /#index4h3

all tests fail

PS:

blackout@h2o-Arch ~ % yaourt -Q | grep mesa 
multilib/lib32-mesa 10.5.2-1
multilib/lib32-mesa-libgl 10.5.2-1
extra/libva-mesa-driver 10.5.2-1
extra/mesa 10.5.2-1
extra/mesa-libgl 10.5.2-1
extra/mesa-vdpau 10.5.2-1
extra/opencl-mesa 10.5.2-1
blackout@h2o-Arch ~ % ls /etc/OpenCL/vendors
mesa.icd
blackout@h2o-Arch ~ % yaourt -Q | grep libcl
extra/libcl 1.1-4
extra/libclc 0.0.1.231373-1

It also doesn't work on my notebook using the nv50 driver which is also WIP
http://www.x.org/wiki/GalliumStatus/

PLEASE DON'T SUGGEST SWITCHING TO CATALYST!!! THX

is there anything I have missed? any ideas?
Thanks in advance guys & girls

that wiki page needs updating, arch stock mesa has supported opencl for some time now.

Your AMD A10-7850K might be too new though, as it's gpu appears to be from the R7 generation.

what is the result of dmesg | grep -i Microcode ?

That may help to determine what firmware is loaded for your gpu.

added

the reason i want to know which firmware is loaded is that seems to be the easiest way to figure out what graphics chipset your card really has.
Apart from R7 generation, amd website doesn't give details about your apu graphic capabilities.

Once we're sure what chipset is in your apu, we can investigate whether libclc supports it.

amd says to use it with the R7 250 for dual GPU.

but I don't want to use amd catalyst driver because catalyst-test crashes when testing opencl
and catalyst needs to downgrade packages, so this is the reason why I don't want amd's driver

Ok, so the APU comes with a Kaveri - GCN 1.1 chipset which is supported by libclc.
for clarity : You also have a dedicated grahics card of R7 250 type in this system ?

In your first post, libcl is mentioned as being installed.
That's the nvidia ICD loader, that seems to support OpenCL 1.0 only .

I suggest you install piglit-git from AUR, then run it's cl.py test profile (check piglit readme).

I think you should also do the same test with libopencl ( AMD ICD loader also in AUR) installed.

no i have no dedicated gpu

i installed piglit but I really have no time to debug it

1 blackout@blackArch ~ % piglit run cl.py results                            :(

yeah there is no builtin folder in the generated_tests folder

Is there OpenCL support using Mesa Drivers?
