[Beignet] CL_DEVICE_NOT_FOUND with Xeon E3-1245 v2 (Ivy Bridge)

[Jason Oster]

Hello list!

I just got beignet to compile from git on Ubuntu 13.04 (had to do some dependency juggling to install llvm and clang 3.3) but when I run utests, I get the following:

parasyte at gorgatron:~/projects/beignet$ DISPLAY=:0 OCL_KERNEL_PATH=./kernels ./build/utests/utest_run
platform number 1
platform_profile "FULL_PROFILE"
platform_name "Experiment Intel Gen OCL Driver"
platform_vendor "Intel"
platform_version "OpenCL 1.1 beignet 0.3"
platform_extensions "cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics cl_khr_local_int32_base_atomics cl_khr_local_int32_extended_atomics cl_khr_byte_addressable_store cl_khr_icd"
terminate called after throwing an instance of 'Exception'
  what():  Error: error calling clGetDeviceIDs with error CL_DEVICE_NOT_FOUND

  at file /home/parasyte/projects/beignet/utests/utest_helper.cpp, function cl_ocl_init, line 340
Aborted (core dumped)


Happens on both master and opencl-1.2 branches.

Also, may be useful:

parasyte at gorgatron:~/projects/beignet/build$ lspci | grep Xeon

00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor PCI Express Root Port (rev 09)
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)
parasyte at gorgatron:~/projects/beignet/build$ cat /proc/cpuinfo | grep Xeon | head -n 1
model name      : Intel(R) Xeon(R) CPU E3-1245 V2 @ 3.40GHz


Any tips or pointers, please?

Thank you!
Jay
