Hi Sylvain,

I reverted to the version 340 nvidia (proprietary) driver, and now it works with the "gr3.7-qt5" branch and an rtl-sdr radio. I did not needed to revert anything on the gr-fosphor side.

However with the XTRX it outputs nothing (starts up properly, no error messages whatsoever, device initialization seems to be fine).

I attached the clinfo output of the working nvidia driver, you might be able to find something in it. The XTRX side of thing is likely something irrelevant to gr-fosphor, as they still not merged XTRX support to gr-osmosdr, I need to use their fairly old gr-osmosdr fork from 2017. The only question is where can I get a hold of them, as I was ot able to find a public forum, or mail list or anything in regards of XTRX...

Non the less, thanks for the help, and if you find something driver-wise on the Nvidia/OpenCL side and want me to test something, I am happy to do it.

Regards,

Csaba

Hi,

> I attached the clinfo output about the version and capabilities of my hardware. Other than this, I am using the proprietary nvidia driver for linux (version 390) with kernel 4.15.0-62-generic, and gnuradio 3.7.13.5~gnuradio~bionic-4.

Sure but you said you used fosphor previously on that machine. My
question was about the versions you were using back then, not the ones
you are running now.

Err sorry it's 306f197108d1a264bebea9f96ac22fa084d402fb

Cheers,
