Priority: medium Bug ID: 64201 Assignee: dri-devel@lists.freedesktop.org Summary: OpenCL usage result segmentation fault on r600g with HD6850. Severity: normal Classification: Unclassified OS: other Reporter: spamjunkeater@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
I am using OpenSUSE 12.3 x86_64 with 3.9 Kernel and ATI 6850HD GPU.
I just experiment OpenCL but I cannot make it with open source tools.
compiled llvm, clang with : ./configure --libdir=/usr/lib64 --prefix=/usr --enable-{optimized,pic,shared} --disable-{assertions,docs,timestamps} --enable-targets="x86_64" --enable-experimental-targets="R600" (for llvm compilation, used http://llvm.org/docs/GettingStarted.html)
And after, compiled mesa-trunk with ./configure --with-gallium-drivers=r600 --prefix=/usr --libdir=/usr/lib64 --enable-{vdpau,texture-float} --with-dri-drivers="" --enable-{gallium-llvm,r600-llvm-compiler,opencl} --enable-glx-tls --enable-shared-{glapi,dricore}
but every utility that I tried, gives a segmentation error to me :-/
