Our documentation-related tools are spread out over various directories;
several are buried in the scripts/ dumping ground. That makes them harder
to discover and harder to maintain.
Recent work has started accumulating our documentation-related tools in
/tools/docs. This series completes that task, moving the rest of our
various utilities there, hopefully fixing up all of the relevant references
in the process.
At the end, rather than move the old, Perl kernel-doc, I simply removed it.
The big elephant lurking in this small room is the home for Python modules;
I left them under scripts/lib, but that is an even less appropriate place
than it was before. I would propose either tools/python or lib/python;
thoughts on that matter welcome.
Changes in v3:
- Now with more caffeine! Properly based on docs-next.
Changes in v2:
- Rebase on top of all of Mauro's changes (the most painful rebase I've
ever done, I think).
- Land everything in /tools/docs/ rather than /tools/doc/
v2: https://lore.kernel.org/lkml/20251023161027.697135-1-corbet@lwn.net/

Good point. I'm not sure about this. Yeah, on normal cases, we just want to run kernel-doc classes, instead of actually executing its binary. Yet, for debugging purposes, it might still be interesting to run it as separate processes. See, right now, if KERNELDOC is not used, it will use imported Python classes, running them directly without creating processes. So, it won't actually call ".../kernel-doc". On such case, in practice, it will actually ignore KERNELDOC when building docs. Now, (after this series), if one runs: KERNELDOC=tools/docs/kernel-doc make htmldocs it will run kernel-doc script as a process. This might be useful for debugging purposes. Also, please notice that KERNELDOC is used on several files: $ git grep -l KERNELDOC Makefile drivers/gpu/drm/Makefile drivers/gpu/drm/i915/Makefile include/drm/Makefile scripts/Makefile.build tools/docs/sphinx-build-wrapper IMHO, we have some alternatives here: 1. completely drop support for KERNELDOC variable. On such case, we need to drop from the script: - kerneldoc_bin - run_cmd() function - remove KERNELDOC from Makefiles and sphinx-build-wrapper 2. keep it as is, which would help debugging (and eventually would allow testing two different implementations of kernel-doc without needing to bisect); 3. change the core of the logic to be something like: # kerneldoc_bin = env.config.kerneldoc_bin kerneldoc_bin = os.environ.get("KERNELDOC") if not kerneldoc_bin: out_style = RestFormat() kfiles = KernelFiles(out_style=out_style, logger=logger) else: print(f"Generating C documentation by running {kerneldoc_bin} binary") this would still allow using KERNELDOC to point to a binary that will handle C files executed as a separate process. Please notice that the current code does: kerneldoc_bin = env.config.kerneldoc_bin This requires an extra logic at the wrapper tool, as this needs to be passed via -D command line option to sphinx-build. That's the reason why several Makefiles also use KERNELDOC env var. If we're willing to adopt this solution, I would simplify the wrapper and the makefiles to not touching KERNELDOC var anymore. For (2) and (3), I would document KERNELDOC somewhere. My personal preference would be (3), but I don't have strong feelings. Regards, Mauro ^ permalink raw reply [flat|nested] 21+ messages in thread

Probably, Jon included the rename of: scripts/kernel-doc | 1 - scripts/kernel-doc.py => tools/docs/kernel-doc | 0 16 files changed, 22 insertions(+), 24 deletions(-) delete mode 120000 scripts/kernel-doc rename scripts/kernel-doc.py => tools/docs/kernel-doc (100%) in 6/8 considering it the right thing to do. Let's keep the symlink of kernel-doc --> kernel-doc.py, at least for the time being. Further tweaks and cleanups around KERNELDOC can wait.

So I clearly hadn't fully understood how this works. Before I went and broke things, the logic seemed to be: If the kerneldoc_bin environment variable is "kernel-doc.py" don't actually run kernel-doc.py, build it internally instead else run whatever program the variable points to ... set kerneldoc_bin to "kernel-doc.py" by default This seems ... a bit obscure. Given that: > 3. change the core of the logic to be something like: > > # kerneldoc_bin = env.config.kerneldoc_bin > kerneldoc_bin = os.environ.get("KERNELDOC") > > if not kerneldoc_bin: > out_style = RestFormat() > kfiles = KernelFiles(out_style=out_style, logger=logger) > else: > print(f"Generating C documentation by running {kerneldoc_bin} binary") > > this would still allow using KERNELDOC to point to a binary > that will handle C files executed as a separate process. This seems like an obvious improvement, and one that, perhaps, should go in ahead of my current series in the perhaps vain hope that we're finally getting to the end of the list of things I can find to break... I can send a patch around in the next couple of days if you don't beat me to it. jon ^ permalink raw reply [flat|nested] 21+ messages in thread

So I have that change working just fine ... only one problem. For this to work, we have to take out the definition of KERNELDOC in the top-level Makefile, otherwise we'll never go the import path. But there are a few other Makefiles, mostly in the DRM area, that need that definition. So I have the docs build working, but I've broken other things, and I think people are getting tired of me breaking things. Possible solutions: - Add a new FORCE_KDOC environment variable that is used instead of KERNELDOC to set the program to run in the docs build. - Keep the current logic that special-cases setting KERNELDOC to scripts/kernel-doc.py and really runs in the imported mode in that case. - Go into retirement and let it be somebody else's problem Anybody have any other great ideas?

Do you mean not running the classes but always run exec() syscall? This will likely affect build time, and prevent further speedup optimizations.
