Benchmark RandomX on L5

Hardware Librem 5
1

Hello

Can you compile and benchmark RandomX speed on L5 https://github.com/xmrig/xmrig ?

This file with functions should help:
    https://paste.debian.net/plainh/acdb96f9

High level workflow is the following:
    1. open terminal
    2. download that file to L5
        wget https://paste.debian.net/plainh/acdb96f9 -O bench.sh
    3. compile XMRig
        source bench.sh
        step_build
    4. connect L5 to some WiFi network common with your PC
    4. setup ssh on L5 for remote access without GUI
        source bench.sh
        step_ssh
    5. use printed commands to reach L5 from your PC
        e.g.
            TRY these commands to reach this device via SSH
            ssh purism@10.0.2.15
    6. start benchmark via ssh
        source bench.sh
        step_bench
    7. revert everything on your L5
        source bench.sh
        step_revert

So you’re telling people to download random stuff from the internet and run it??

If this is an important or worthwhile benchmark then I myself would rather that it goes into an official repository.

@kieran,
The benchmark itself is https://github.com/xmrig/xmrig.

The content of this link can’t be changed by me https://paste.debian.net/plainh/acdb96f9.

These are just shell help functions adopted for Librem 5 to automate all steps during benchmark.

There are some official docs:
compilation step https://xmrig.com/docs/miner/build/ubuntu
benchmark step https://xmrig.com/docs/miner/benchmark
ssh setup step https://developer.puri.sm/Librem5/Development_Environment/Phone/Development_Tools.html

I personally prefer automated shell code instead of reading a lot of text, therefore i’ve created that shell help functions.
