Phantom SDR Plus & RX888 - setup

Martin G8JNJ · Sep 25, 2024, 11:24 PM

Understood.

I suggest the installation instructions need to be expanded, to try and ensure that any dependencies are dealt with, in the correct order.

As PhantomSDR-Plus becomes more widely adopted, these types of problems are likely to get worse, unless a relatively foolproof process is developed.

I'm certainly not skilled in Linux, but there are many who are even less proficient than myself, and part of my extended attempts throughout today, were in order to try and make things easier for them in the future.

I sometimes think that when folks are very familiar with a process, they assume everyone else is too, and this makes it a lot harder for others to follow.

It always reminds me of when I was being taught maths at school. It usually followed a step by step, methodical path, up to a certain point, then the teacher would say something like, "and from this we can deduce that" and then miss out several vital stages, before magically arriving at the answer.

There are good mathematicians, and good teachers, but unfortunately they are often not the same person.

Please spell things out, in detail, so that folks who don't know, can follow the various steps, and understand what is happening. We can then learn better.

Regards,

Martin

The thing is, OpenCL isn't the same for all CPU's...so there is no simple solution.
Try Cuda, I have, couldn't work it out.

The problem isn't PhantomSDR+ but the manufacturers of the hardware.

Intel alone has dosens of different CPU's and GPU's that all have a different driver, most combined into one, but not all.

AMD has dropped OpenCL as name and has ROCM and other names to do OpenCL.

Broadcom also different. nVidia Cuda that is compatible only with nVidia but is also different over various cards.

There is no simple answer to this.

As for the OS, Ubuntu 22.04 is the one to use, Mint 21.3 uses the same base and can be used without problems. They just refuse for things to be done in snapd that could break updates.
Mint uses the normal package distribution.

We have spelled everything out as best as we could.
No easy solution possible.

Martin G8JNJ · Sep 26, 2024, 12:41 PM

Hi Bas,

Yes, I understand, and I also appreciate your assistance in trying to get it to behave as intended.

I have followed most of the instructions, and bought specific hardware that I thought would ease the process, but it would seem that you are correct in saying "No easy solution possible".

I'll try again when the replacement for the faulty PC arrives.

Regards,

Martin

Bas ON5HB · Sep 26, 2024, 01:42 PM

Yeah, probably something wrong as the Skylake CPU you tried to use has the most simplistic way of supporting Intel OpenCL.

It should have worked and recompiled almost by itself

Or lastest and greatest package:

https://github.com/intel/compute-runtime/releases

It should have worked, almost all ways of doing it do support that CPU...therefor baffled me it wouldn't work.

Martin G8JNJ · Sep 26, 2024, 02:12 PM

OK, I just followed your recommendation and bought a HP Elitedesk PC i5-6500T 3.1Ghz, I wasn't aware there were further considerations.

If I'd know I could have asked for a different replacement, but it's currently being shipped, so I'll have to make do with what I've chosen.

You live and learn...

My testing server, just freed this as my desktop machine

Intel(R) Core(TM) i5-6500T CPU @ 2.50GHz

I installed Ubuntu 22.04 fresh.

Now I'm going to install OpenCL and will tell you in about an hour if I have the same difficulites, however I do not expect such.

Martin G8JNJ · Sep 27, 2024, 09:48 PM

Hi Bas,

I'm responding in this thread, to avoid contaminating your new one.

The replacement PC arrived.

I made a fresh Ubuntu 22.04 build and followed all the updated instructions to the letter.

clinfo indicated that it had installed correctly.

Number of platforms 1
Platform Name Intel(R) OpenCL Graphics
Platform Vendor Intel(R) Corporation
Platform Version OpenCL 3.0
Platform Profile FULL_PROFILE

I then proceeded with the installation of PhantomSDR-Plus

To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).

To configure your current shell, you need to source
the corresponding env file under $HOME/.cargo.

This is usually done by running one of the following (note the leading DOT):
. "$HOME/.cargo/env" # For sh/bash/zsh/ash/dash/pdksh
source "$HOME/.cargo/env.fish" # For fish

Cont.

I tried to run PhantomSDR-Plus but, it came up with errors.

wessex@phantom:~/PhantomSDR-Plus$ sudo ./start-rx888mk2.sh
[sudo] password for wessex:

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I edited the toml files and put none in place of opencl.

It started without any obvious errors, and I could get a browser to connect, it asked me to tap to start the audio, but there was no audio or waterfall. Restarting PhantomSDR-Plus and refreshing the browser, had no effect.

I went away for a while to have my evening meal, and I've just returned, refreshed the browser, and the audio and waterfall are running.

So, as before, it is still not recognising opencl.

Regards,

Martin

Martin G8JNJ · Sep 27, 2024, 10:53 PM

I suspect something has changed from earlier versions with the way opencl is deployed, but I'm not a software guy.

https://www.intel.com/content/www/us/en/developer/articles/tool/opencl-drivers.html

Intel® SDK for OpenCL Applications is EOL. The transition to Intel® oneAPI and its unified, cross-architecture programming model brings greater efficiency and reuse across hardware targets. See the Intel® oneAPI Programming Guide for information migrating OpenCL code and OpenCL interoperability by way of SYCL* objects.

Maybe after meal you restarted your terminal and reconnected? Because after the rust installation this is needed. Try it with opencl again and restart and send the error if any

Martin G8JNJ · Sep 28, 2024, 05:11 PM

No, I had just left the browser running, with a blank waterfall, when I returned I refreshed the tab, and it was working.

Without Opencl running, I can just about achieve a 60MHz sample rate, above this it has severe audio dropouts. I'd hoped to be able to have a slightly greater margin.

The next job it to somehow implement an automatic startup on boot or power restoration. I guess a chron job would achieve this, but there should really be an inbuilt option to start on boot.

Martin

Looks like you didn't install the libaries.

You never told us the install showed the libraries.

Also, I do not run a desktop, that is disabled in grub at boot.

GRUB_CMDLINE_LINUX_DEFAULT="systemd.unit=multi-user.target usbcore.usbfs_memory_mb=2048 pci=noaer"

Maybe you have a desktop running? I never do. Blackbox only.

Martin G8JNJ · Sep 28, 2024, 06:24 PM

Which / What libraries ? Do you mean the OpenCL deb files or some other prerequisites that should have been part of the Ubuntu install ?thing else ?

I followed all of the instructions, step by step, and as described.

I'm not running the Linux desktop, it's headless, and I'm SSHing in, but I do have a VGA monitor connected, so that I can confirm that it is booting up correctly.

Regards,

Martin

You must have missed something, as I wrote it while doing it.

https://www.phantomsdr.fun/index.php?topic=58.msg331#msg331

I can not understand why it keeps failing on your part, sorry I don't.

I especially took my Desktop machine, formatted it, and started from scratch.

I wrote down all steps.

It's beyond me why you can't get it working.

Maybe time to ask a Linux-nerd to help you? I'm baffled why you didn't get it working, again.

Sorry mate. I'm clueless at this point.
