Control: retitle -1 mesa-opencl-icd,beignet: installing together breaks all ICDs Control: reassign -1 mesa-opencl-icd,beignet Control: found -1 mesa/10.3.2-1 Control: found -1 beignet/0.9.3~dfsg-1
It appears I forgot to test mesa+pocl without beignet installed: pocl then works, i.e. the problem only occurs if both mesa-opencl-icd and beignet 0.9.3 are installed, but then breaks both beignet and pocl (can someone with the hardware test whether it breaks mesa-opencl-icd too?) Installing libllvm3.5-dbg, starting an OpenCL program under gdb (e.g. gdb --args python3 two_icd_test.py ) and pasting this at the gdb prompt: set breakpoint pending on dprintf lib/Support/CommandLine.cpp:110,"%p %p %s\n",RegisteredOptionList,this,this->ArgStr break lib/Support/CommandLine.cpp:110 if !strncmp(this->ArgStr,"asan-instrument-reads",20) commands bt c end set pagination 0 run shows many LLVM options being added to the same RegisteredOptionList object twice, once by libOpenCL.so and once by beignet, hence the error. (Nothing special about asan-instrument-reads, just a way to get one backtrace per set instead of per option.) Given that pocl does add these options when only it is installed, I don't know yet why beignet+pocl or mesa+pocl adds them once (so works) but mesa+beignet or mesa+beignet+pocl adds them twice (so fails). As beignet 0.9.3 isn't going to be in jessie, and needs an upload for #768090 anyway, it should probably carry the Breaks: until we can find a real fix. -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
