Re: fosphor sink block error

Gwendoline:

I think you may have conflicting versions of GNURadio and/or Fosphor. I have had this error before as well. 

I use fosphor on a daily basis on both GNURadio 3.8 and 3.9 and I can confirm that it does work on several different nvidia GPU’s as Sylvain said. I have had some issues relating to the drivers for the GPU, but they were usually not related to GNURadio. I also have a machine without a GPU and am running Fosphor using the Intel CPU implementation of OpenCL found here:

https://osmocom.org/projects/sdr/wiki/Fosphor#Intel-CPU-OpenCL

You should start by uninstalling all previous versions of GNURadio and Fosphor before continuing. You’ll need to make sure that all libraries have been removed from your system before trying anything else. 

Then, follow the build procedure for GNURadio 3.9 as 3.7 is EOL. 

For Ubuntu 20 you’ll also need to make sure your computer is actually using the NVIDIA driver as it sometimes defaults to the nouveau driver even if NVIDIA is installed.

Hi,

I install the package but before testing it I see a new problem.

Gnuradio is in version 3.9.4.0.

The fosphor sink block is in error so I can't run the flowgraph.

No matter what Window type I put, I have this error in block parameters:

Param - Window Type(wintype):
    Value "firdes.WIN_BLACKMAN_hARRIS" cannot be evaluated:
    type object 'gnuradio.filter.filter_python.firdes' has no attribute 'WIN_BLACKMAN_hARRIS'

Param - Window Type(wintype):
    _expression_ None is invalid for type 'int'.

Is it because of how I install gr-fosphor ?

Regards,

Gwendoline

Hi,


If you're using Ubuntu, you can try the intel-opencl-icd package which
is the binary package for https://github.com/intel/compute-runtime
which is the OpenCL driver for Intel GPUs.
However, I'm not sure anyone has ever run fosphor with it ... not sure
if it supports the features required, I only tried on AMD and NVidia
GPUs as I don't have any Intel GPU supporting that driver.

Cheers,

  Sylvain
