[Pkg-opencl-devel] Bug#885423: Bug#885423: Beignet: self-test failed: (3, 7, 5) + (5, 7, 3) returned (6, 7, 5)

[Rebecca N. Palmer]

To identify more precisely what isn't working, please install the 
beignet-dev package and run
OCL_IGNORE_SELF_TEST=1 /usr/lib/x86_64-linux-gnu/beignet/utest_run

Is this a new problem (i.e. have you used it without this error before), 
and if so, when did it start?

darktable doesn't actually use beignet by default anyway ( 
https://sources.debian.org/src/darktable/2.4.0-1/src/common/opencl_drivers_blacklist.h/?hl=36#L36 
), so it should be fine to ignore this message for now, but as it 
happens at driver load, it is likely to also affect any other 
OpenCL-using applications you might have.

What might be the same bug has been reported upstream as 
https://bugs.freedesktop.org/show_bug.cgi?id=102137 and 
https://bugs.freedesktop.org/show_bug.cgi?id=101485 , but they don't 
have a fix.
