Mesa 10.0 Delivers Many Exciting New Features

[geearf]

Oh I was just using the simple test from that page nothing more.

I also tried the opencl examples linked in the wiki, and about 1/3 of them fail :/

How did you get them all to pass? Did you run them without X?

Well I managed to install everything, but a simple test from here http://wiki.tiker.net/OpenCLHowTo crashes...

That how to is for the Catalyst driver. I am not sure it should work with the OSS driver.
Look here for opencl on mesa/gallium (examples at the bottom of the page):

http://dri.freedesktop.org/wiki/GalliumCompute/

While those worked for me (reported succcess, the GPU was reset after each test (gpu hang for more than 10000 msecs dmesg error). Maybe they are designed to be run without an X server.

At least up to rc-2 it was required when enabling opencl.
I have not tried fiddling with it in the master branch.

for mesa, llvm needs to be in shared mode

This is no longer required.

I will try again with mesa-master, I only got llvm and libclc master with Mesa 10.2.
Let's see if that makes a difference.

No difference... :/

(Is there a bloody way to edit that I am missing?)

Thanks, I was trying to reuse existing pkgbuilds, but maybe I should have written mine instead

I was so excited for the OpenCL changes, but to enable them is not that easy...
One need to recompile Mesa with the enable flag, ok not too hard.
BUT, to do that you need latest libcl, ok easy.
BUT, for that you need latest clang, and for mesa, llvm needs to be in shared mode.

Somehow the combination of all of that is that I have not been able to get there yet...
Even with all the beautiful pkgbuild in aur... Hmmmm

I followed the wiki pages and it works.For llvm you have to enable shared mode or it wont work.
I have built it this way (the disable docs i put there because i had some ocaml related build errors initiall, not sure its needed):

./configure --enable-experimental-targets=R600 --enable-targets=x86_64 --enable-shared --disable-docs --enable-optimized

Dont forget to clone clang too in the llvm git's tools folder.

r200 mega driver loads fine here if xserver 1.14 is patched with:
