[PATCH] regex/cn9k: remove rule compiler

[PATCH] regex/cn9k: remove rule compiler

[Thomas Monjalon]

Nobody knows how to build the feature.
When the dependency "rxp_compiler" is found,
the header file is not available:

drivers/regex/cn9k/cn9k_regexdev_compiler.c:12:10: fatal error:
	rxp-compiler.h: No such file or directory

It seems that it depends on a proprietay library.
According to what was discussed in the Technical Board:
http://mails.dpdk.org/archives/dev/2019-June/135847.html
the dependency must be "freely available".

Yes. it depended on proprietary library owned by NVIDIA now. Not sure
Marvell has rights to publish it "freely available".
In order to avoid forking this library, better option to make this
library as public. Also, it looks like the library itself won't have
proper installation procedures that is the
reason for conflict as documented here in
https://bugs.dpdk.org/show_bug.cgi?id=1232.

If that is not an option for other original owner, I think, it should
be removed and accept this patch in the true sprint of open source.

Interesting. Then what about the GPU support which currently requires
proprietary NVIDIA CUDA library

CUDA can be downloaded.
It is even packaged in many Linux distributions.

Thanks for the clarification.
So the real issue is not that it needs a proprietary library but it is
that the library is not available without special license. CUDA does require
accepting a free license which may be a problem for some people who have
lawyers who read the fine print.

The policy about dependencies should be made more explicit in the documentation.

No you don't get it.
The problem is that the dependency must be downloadable on Internet.
CUDA is downloadable.
The dependency for Marvell regex is not available on Internet.

It could be detailed in the contributing guide.
