SoapySDRServer segfault #26

Closed Geremia closed 6 years ago

Geremia commented 7 years ago

Using the Osmocom source block with Soapy Remote, I sometimes get a segfault:

Here is what GNUradio says:

Here is what the remote server running SoapySDRServer says right before it segfaults:

Is this because the server cannot keep up with the requested sample rate?

rrobinett commented 6 years ago

Sorry that I've been too busy to test, but I will try in the next several days. Thanks

Strykar commented 6 years ago

@SDRplay fix works! CubicSDR can now receive data, though anything over 1 Mhz seems to be too much.

SDRplay commented 6 years ago

If you've still got debug enabled that will be a problem. Also, 16bit I/Q data will be quite bandwidth hungry at higher sample rates. If the library supports it, you might try 8 bit mode. May @vsonnier can confirm whether that is supported. To be honest remote data is really only suitable for small bandwidths on any system.

Strykar commented 6 years ago

@SDRplay Debug is disabled in head now, so it isn't enabled. I have a 1Gbit Ethernet connection, how much bandwidth do we need? Is this an issue of network bandwidth or small SBC's being unable to stuff that bandwidth without dedicated PHY's like RPi?

SDRplay commented 6 years ago

Most SBCs like the Raspberry Pi have an inherent problem because ALL of the peripheral data is shared on the USB bus including the network port. I'm not sure about the Odroid. I've backed a new SBC on kickstarter (https://www.kickstarter.com/projects/librecomputer/libre-computer-board-tritium-sbc-linux-android-7-n) that doesn't have this shared bandwidth which I hope to receive in the next couple of months and I'll be able to gather some data on throughput. You'll also need to consider the processing requirement and the latency huge sample rates will create. It may be worth seeing if there are any options you can use in SoapyRemote to change the CPU vs bandwidth - maybe @guruofquality or @vsonnier can comment? What sort of sample rate were you expecting?

Strykar commented 6 years ago

The Odroid has a dedicated PHY and does not share the bus with USB devices, it's one of the reasons I chose it, along with boatloads more CPU power over the RPi. I can understand latency being an issue, and am happy to work within these limits. TBH, looking at https://libre.computer/products/boards/all-h3-cc/ I don't see how this is faster than an Odroid, it even has just 100 Mbit LAN?

Speaking of CPU, I'm awaiting delivery of an all Aluminum case for the Odroid, perhaps that can help with thermal throttling running GQRX and accessing it via remote X. If not, this might a better option: https://www.notebookcheck.net/Benchmarks-for-the-Intel-Hades-Canyon-NUC-with-Core-i7-8809G-CPU-and-RX-Vega-M-GPU-leak-out.287220.0.html

vsonnier commented 6 years ago

@Strykar you can try CS16 format (the most compact one) and tuning the MTU among other things: remote_settings Don't get too excited by the 8Mhz sample rate, it is just a localhost test :)

rrobinett commented 6 years ago

I am finally able to resume work on this.

Because my original Pi environment was corrupted I flashed the latest raspberian and am trying to cleanly build Soapy following the instructions of @vsonnier, but I get errors, first in:

cmake .. -DCMAKE_BUILD_TYPE=Debug

Then when I execute cmake :

pi@raspberrypi:~/SoapySDRPlay $ git checkout -b master origin/master

fatal: A branch named 'master' already exists. pi@raspberrypi:~/SoapySDRPlay $ mkdir build pi@raspberrypi:~/SoapySDRPlay $ cmake .. -DCMAKE_BUILD_TYPE=Debug CMake Error: The source directory "/home/pi" does not appear to contain CMakeLists.txt.

What am I doing wrong?

guruofquality commented 6 years ago

It cant find SoapySDR development files. Did you install SoapySDR? if so can you share the output of make install?

rrobinett commented 6 years ago

No. I confess I am lost in the web site looking for instructions on how to set up this whole development environment

vsonnier commented 6 years ago

@rrobinett The problem may comes from

fatal: A branch named 'master' already exists.

And a lack of the Soapy dependencies, like in #35.

So: Delete all the SoapySDR , SoapySDRPlay, SoapyRemote directories, (if any) and do the following:

git clone https://github.com/pothosware/SoapySDR.git
git clone https://github.com/pothosware/SoapySDRPlay.git
git clone https://github.com/pothosware/SoapyRemote.git
cd SoapySDR
mkdir build
cd build
cmake ..
make -j4
make install
ldconfig
cd ..
cd ..
# Now we build the SDRPlay module for Soapy
cd SoapySDRPlay
mkdir build
cd build
cmake ..
make
make install
cd ..
cd ..
# And we build SoapyRemote
cd SoapyRemote
mkdir build
cd build
#cmake ..
cmake .. -DCMAKE_BUILD_TYPE=Release
make
make install
cd ..
cd ..

From @loughkb scripts. And you need to be root I think to execute them (for the ldconfig part I assume)

rrobinett commented 6 years ago

Thanks for those clear instructions. Unfortunately my build attempt fails at the same place:

Sorry, I was building on a fresh raspberrian OS and had failed to download and install the SDRPlay driver from their site. Having done that I have been able to build and run SDRServer.

However I do get some compile warning messages and I am missing the Avanhi library. How do I get that?

thanks

That's an optional library. As the note says, install libavahi...

sudo apt-get install libavahi-client-dev

guruofquality commented 6 years ago

So it looks like this bug got sorted out in soapysdrplay. Its quite a long issue that this point, and it wasn't really an issue for the SoapyRemote codebase. I'm going to close it out. Thanks for everyones help in tracking this down!
