My mind says my tracker is good as it is in Rust but my heart says "rewrite it in C, you want to do it Jarkko, let's make it small and tight just the way you want it, together".
Can't resist... the force is too strong... :-)

The first version of loader/saver for Polyend's MT project files and MTP pattern files done :-) PTI instruments were already. Scaffolding done also for wavetable and granular synthesis...

Documentation of internals will follow to kernel/rootns.c and make htmldocs works too (Documentation/ is generated from DOC-comments).

I call the new namespace as root namespace. It's reduced and focused version, and re-defining root is the whole point.

I could perhaps create (maintained) DKMS repository of swcam driver since V4L2 subystem does not want it.
It addresses at least all the security issues of v4l2-loopback, which is in wide use.

I got crazy idea of dawproject import and export for this tracker project (within limits).
Doing an export from tracker to DAW can generate quite large dump of data in the worst case given that in each lane instrument can change per step and other hand commonly in DAWs each instrument has a dedicated lane.
Import can simply require sampled instrument only and then figure out whether the dawproject file can be mapped to tracker patterns.
To 16 tracker lanes one can fit obviously at minimum 16 DAW lanes.
But depending on many factors one can take advantage of re-usability of lanes for as many instruments as there are steps.

I really enjoy working on this tracker project. When I got pattern editor, I knew that it will become something. It will take at least a year to really nail every bit but it has the critical mass of getting done (eventually) :-)
Very early work on sample editor.

@penguin42 Ya, got it. I just put a reminder for myself :-) It's good to point this out.

@penguin42 I can put a remark before diffstat to my kselftest patch and on request can consolidate them.

@penguin42 I have absolutely have no idea and blindly just copied one from bpftool ;-)

I guess I just follow the lead :D
❯ find -name json_writer.c
./tools/testing/selftests/container/json_writer.c
./tools/testing/selftests/bpf/json_writer.c
./tools/bpf/bpftool/json_writer.c
./tools/net/ynl/ynltool/json_writer.c
Maybe we should have shared json_writer.h/c for selftests?

This looks "pre-done" :-)

Better to distance off for a while and then revisit.

I thought that rather than focusing on reversing Polyend Trackers MT song format it is better to build a "DAW" that can support its features. I'd figure the lack of such program has blocked any major progress.
So there you have it I'm building a retro-modern tracker ;-)

As long as LLMs don't ask the questions for you, there's no problem with LLMs IMHO :-) Iterating the question is everything in engineering. Everything else is relatively nothing.

After refurbishing dhowell's patch set for a while I end up to the situation where I you realize that you're chasing for solution rather than for the problem. So time to pivot.
So I'm thinking that most of it could be possibly done by adding a new feature for sys_clone() instead... Need to experiment with this. I.e., chasing for the problem now...
