Package: src:linux
Version: 3.16.5-1
Severity: important
Control: affects -1 beignet
Control: tags -1 fixed-upstream
X-Debbugs-CC: s...@debian.org,pkg-opencl-de...@lists.alioth.debian.org
In current jessie, beignet (OpenCL for Intel GPUs, 0.8-1.1) is
non-functional:
$ sudo apt-get install beignet python3-pyopencl
$ python3 beignet_test.py
python3: /tmp/buildd/beignet-0.8/src/intel/intel_gpgpu.c:427:
intel_gpgpu_check_binded_buf_address: Assertion
`gpgpu->binded_buf[i]->offset != 0' failed.
Aborted
It had previously worked in Ubuntu 14.04 (beignet 0.8-1, linux 3.13.0)
on the same hardware (i5-3230M). (beignet isn't in Wheezy.)
beignet's upstream documentation [0] says this is a known issue with
3.15/3.16 kernels and suggested the workaround
$ sudo sh -c "echo -n 0 > /sys/module/i915/parameters/enable_cmd_parser"
which made it work, but the description [1] suggests this will break
some OpenGL functionality and might be a security risk.
This is fixed upstream by [2]; I haven't yet tried this.
