Re: [Discuss-gnuradio] gcellized FFTW has broken gcell block

[matty]

Thanks,

i have already a PS3 with Frimware 3.15 an know about Sony's OtherOS removal.
Now i've localized the issue: By installing another Package - and it was not the gcellized FFTW - 
my PYTHONPATH was overwritten. I had to set him new.

Now I set up several Benchmark-Tests like benchmark_nop and benchmark_dma.
I used qa_fft.py as simple offload, but saw only 2 SPEs working (i used spu-top to verify).
I think i have to use a bigger FFT e.g. 4K because in qa_fft.py it's only used 32 FFT.

Could you tell me, how to use FFTW-WIP as workload for gcell?
I have a FFTW-WIP binary in /usr/local/bin, which can be execute pretty well.
But I think, i have to recompile GNU Radio with FLAG to use FFTW-WIP.
Or will FFTW-WIP be used automatically instead of normal FFTW3?

Thanks in advance!

No further development.  You can't buy a new PS3 that will run Linux.
Sony pulled the "OtherOS" feature, and if you happen to allow a
"working" PS3 to update it's firmware, you'll lose the feature too and
will no longer be able to run Linux on the one you already have.

Thanks.

Matty,

I haven't found time to look at your real problem, but I wanted to
make sure that you knew about Sony's removal of the OtherOS feature,
and to warn you not to upgrade the firmware on your PS3.
