trouble running lkp-tests
hi all,
anyone familiar enough with running lkp-tests to recognize these errors ?
1st, from inside a virtme VM -
bash-5.2# /usr/local/bin/lkp split-job --compatible

somehow, ruby is broken / unavailable inside the VM.

I'm thinking of something like this: * If you want to learn about USB drivers, have a look at the very simple foo-driver. Then, you could look at bar-driver. If you grasped all the concepts, have a look at veryadvanced-driver. * For char drivers, you could start with this driver, then this other driver and end with... * For block drivers... * For network drivers... I think this might be extended to core components of the kernel, although it might be a bit more complicated: * For process creation and destruction have a look at this. For advanced topics, have a look at that (this would be specific code parts/snippets). * For memory management, have a look at this for simple usage/understanding, and that for advanced topics. Sometimes it can be a bit overwhelming to open foo.c and get lost in the details. Do you know if there is such a list? Would it be difficult to create one?

Respectfully, you are completely missing the point of this mailing list. You started by asking for a list of programs that run on Linux; when that was provided, you changed your mind entirely and insisted that you wanted to know more about Linux internals like device drivers and memory management and so on. Now you're suggesting you will (finally?) buy a book and will further consult ChatGPT. Nowhere here have you demonstrated that you've actually put in any effort of your own to start learning. Your entire approach seems to be, "Could everyone drop what they're doing and teach me all about Linux?" One starts to suspect you haven't even installed Linux to start using it. This mailing list is for *kernel* newbies -- people starting to play with the kernel and who have *specific* questions about something they're trying. You, on the other hand, are asking to be spoon-fed the most basic information about simply *running* Linux. You need to go and invest some effort in learning the simplest things about Linux, and not ask others to do that for you. rday ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Will buy a book. Thank you. Debugging the whole source code of Linux, might be a bit tricky at the beginning. Will try ChatGPT.

This link is good. However it is listing all the software which runs on Linux-kernel.
