Yes, you are right, the device 162b is BDW and missing. The patch is ok.
In fact, this series device ids all are all missing, include 0x160B(GT1), 0x161B(GT2), 0x162B(GT3), could you send to a new version patch to include them?

The Failed test, test_load_program_from_spir has been fixed.
The other fails, maybe half’s precision issue, can you run these tests standalone(utest_run –c test_name) and print the input and output? We will check it.

Subject: [Beignet] NUC5i7RYX Intel Iris Graphics 6100 support

I have a new Intel NUC model NUC5i7RYX that has a core i7 with "Iris graphics 6100". Trying to use beignet opencl installed from the latest source checkout, I got an "clinfo error, unknown device: 162b".

I poked around the source code and found that the device definition is missing for this GPU, so I added it. The patch is at the end of this message. The string contents and comments are entirely guesswork on my part, but make sense to me in any case. The patch appears to work fine.

utest results are the same as I get on an NUC5i5RYK which has the Intel HD Graphics 6000:
  total: 762
  run: 761
  pass: 758
  fail: 3
  pass rate: 0.996058

Failed tests are:
compiler_half_math_sin()    [FAILED]
compiler_half_math_fmod()    [FAILED]
test_load_program_from_spir()    [FAILED]

I'm pretty sure I put things in the right place, and this allows me to use OpenCL for my purposes.
