I have installed pocl. make check shows all 145 tests passed. The build shows that 

--******** Enabled features:
......

-- OCL_DRIVERS (Drivers built): basic pthreads
......

But clinfo command shows only pthreads as the only device for the pocl platform. Is there a way to enable the basic device? I want to add a custom opencl device to pocl. Understanding basic device implementation in pocl seems to be a good starting point.

According to the pocl documentation, the basic device hast to be enabled explicitly by setting the environment variable POCL_DEVICES to basic:

POCL_DEVICES is a space separated list of the device instances to be enabled. This environment variable is used for the following devices:
- basic A minimalistic example device driver for executing kernels on the host CPU. No multithreading.

So you should be able to use the device by calling POCL_DEVICES="basic" clinfo.
