[SYCL][Doc] Move internal design docs #5556

gmlueck · 2022-02-11T22:37:51Z

Move all the internal design documents to a separate directory. This
declutters the "sycl/doc" directory, making it easier to find the
end-user documentation. It also moves several documents out of
"sycl/doc/extensions" which were not actually extension specifications.

We decided that the "sycl/doc/dev" directory should hold documents
related developers of DPC++ (not for users of DPC++), so rename it
accordingly.

We decided that the "sycl/doc/dev" directory should hold BKMs (best known methods) for developers, so rename it accordingly.

I don't think the names "internal design" and "development BKMs" are consistent.

The design documents are only "internal" to the project, so I'm not sure what extra information "internal" is supposed to convey. The fact that the development BKMs aren't marked internal suggests that they're for "external" developers (end users?) but the ABI policy guide at least is targeted at developers who will be opening PRs.

I don't feel strongly about this, but suggest the following names instead:

design/ => design documentation
developer/ => developer documentation (removing BKM because its meaning isn't obvious)

Maybe everything else could go in:

user/ => user documentation

....but I appreciate that might break documentation builds and such.

    The workaround is to rebuild the application.

Can we rename this to development-policies or development-guidelines ?
BKMs are something one may ignore, that's not what ABI doc is.

developer documentation as suggested by John is also ok

I'm not opposed to changing the directory names. Does everyone like the following:

sycl/doc/extensions - Extension specifications

sycl/doc/design - Design documents

sycl/doc/developer - Developer information

Personally, I think it's better to keep end-user documentation directly in sycl/doc because it is more prominent. I also think there are more likely to be external links to those documents, so there is some value to keeping them where they are.

LGTM as well.

I would like to hear from @alexbatashev to see if he agrees. Updating all the links is kind of a pain, so I only want to do it once more. :-)

I renamed the directories in b00236c. I also changed the titles in the Sphinx documentation in 429f2da

I think we should fix syntax errors and include these documents. @gmlueck, could you file a ticker for that issue, please?

Yes, I agree. I'll do this once we agree on the directory name.

I filed an internal bug report.

Rename these two subdirectories based on review feedback.

Just noticed the article published today https://www.intel.com/content/www/us/en/developer/articles/technical/expanding-oneapi-support-for-languages-and-accelerators.html?cache=false#gs.p79jmz, which references https://github.com/intel/llvm/blob/sycl/sycl/doc/CompilerAndRuntimeDesign.md. This PR breaks the link.
@pglowney, do you know if we can update the article?

pvchupin · 2022-02-15T21:42:54Z

Ping @intel/llvm-reviewers-runtime for review

It was adjusted to the new link.

@bader @pvchupin: It would be good to merge this soon. The end-user article noted above points to the new location of this design document, so the link will be broken until this PR is merged.

If we are only waiting for someone from @intel/llvm-reviewers-runtime, the changes in the runtime are extremely small. These two files just had a 1-line change to a comment:

sycl/source/detail/context_impl.hpp
sycl/source/detail/program_manager/program_manager.hpp

And this file had a few trivial changes to the pathname in an output string:

sycl/tools/abi_check.py

It think it takes time to propagate the update to the web site. I still see the old link:

I see the new link. You probably have the old version cached in your browser. Try reloading with CTRL-refresh.

bader · 2022-02-16T14:18:29Z

CTRL-refresh doesn't help, but removing ?cache=false from the URL does.

Just looking at the (very good) documentation. Would it be possible to have only vector graphics format for images like SVG instead of JPG?
I have just noticed a renaming of sycl/doc/design/images/plugin-lifetime.jpg. Perhaps the source is lost...

Yes, I think this is a good idea for new documents that we add. Currently, I think we have only these images that are not SVG:

sycl/doc/images/missing_sycl_dll.png
sycl/doc/design/Multi-source-compilation-flow.png
sycl/doc/design/images/plugin-lifetime.jpg

I don't know what happened to the source files for those images. If we need to edit them, we may need to recreate them as SVG.

alexbatashev · 2022-03-08T07:45:04Z

sycl/doc/images/missing_sycl_dll.png

That's a screenshot. I can hardly imagine how we can covert it to SVG.

keryell · 2022-03-08T23:03:01Z

Ah yes, good point.
Otherwise use oneDNN running with DPC++ to do an image comprehension by recognizing the text and the font, then generate the SVG? :-)
