Sipos Csaba dchardware at gmail.comHi 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
