If you run darktable -d opencl in the terminal, you will be able to see if
opencl is activated.
This line will appear somewhere in the middle:
[opencl_init] OpenCL successfully initialized.
If opencl is not available, there will be something like opencl is not
available for this system. Darktable will start, but opencl will not be
activated.
As for Haswell or not, Haswell is just a CPU architecture. It's the newest
one out there now from Intel, yours is the 2nd generation processor, named
Sandybridge. I915 is the graphics driver loaded. If opencl can run on the
integrated graphics from your Sandybridge processor, chances are it will
run on a Haswell integrated gfx card, unless the drivers for them are not
updated for opencl support.
Having said that, if you didn't install the experimental drivers from, say,
xorg-edgers, I doubt opencl will be supported. So far I think none of the
open source drivers for Intel, AMD or NVIDIA cards have opencl support.
