Fwd: gr3.7-qt5 --> CL Error: Unable to queue clear of spectrum buffer
Hi Sylvain, Resent it to the list as requested. I tried to use the 'gr3.7-qt5' branch today, and after successful compilation, I am getting this error message on the terminal: [+] Available device: 0:0 <NVIDIA Corporation> NVS 4200M [+] Selected device: NVS 4200M [!] CL Error (-59, /root/gr-fosphor/gr-fosphor/lib/fosphor/cl.c:438): Unable to queue clear of spectrum buffer I attached the complete output of the event, if you want to take a look. I also attached the screen how it looks during the run. OpenCL works fine otherwise, and I used gr-fosphor successfully on this same machine before. I am on Ubuntu 18.04.03 LTS with the proprietary Nvidia driver (v390). The gnuradio is 3.7.13.5 (comes with the ubuntu repo, not compiled from source). If you have any idea, or you need more info, debug log etc. please let me know. Regards, Csaba

Which version did you use and with which drivers ?
I am on Ubuntu 18.04.03 LTS with the proprietary Nvidia driver (v390). The gnuradio is 3.7.13.5 (comes with the ubuntu repo, not compiled from source).
Try reverting a269271fed026d5e633fa45f4dd5db125133f453 and see if that helps. Cheers, Sylvain
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. I tried to find that commit you are referring to, but it seems it is no in the git log (or at least I cannot find it). Can you take a look if it is correct? Thanks in advance!

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.

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.

Some extra info: It seems for this old card (9400M), Nvidia recommends driver 340 on their PPA. Of course, ubuntu recommends the wrong (390) version to be installed, and there is no alarm or anything during the process... Anyway, I think this is it: might need to switch to a newer card... XTRX with gr-fosphor also works, just needed to add an extra ARG to the command line: osmocom_fft -a xtrx -A RXW -s 4000000 -f 804000000 -F Thanks again for the help!
