Re: [TF-M] [RFC] TF-M Documentation Contribution Format

by Gyorgy Szing

Hi, I think this effort should be done together with other tf.org projects using the same technology (Sphinx). Can you pls sync up with the TF-A team? Related to the details: * I suggest referring to the RTD style guide [1] instead of Python. The text is much smaller, does not cover topics we don’t need and your points 1-5 are aligned. Point 6 is conflicting as RTD allows 6 levels. * I disagree on 11. “A drawing is worth 1e3 words”, and hiding these at the end is not a good practice. * 12: do we really need this? How often are people doing such things? * 13 is ok 😊 * 14: might be too strict. What if a term is over used and may have a different meaning is some sections (i.e. platform, host, etc...). [1] https://documentation-style-guide-sphinx.readthedocs.io/en/latest/style-gui… /George From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Minos Galanakis via TF-M Sent: 30 June 2020 16:23 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: [TF-M] [RFC] TF-M Documentation Contribution Format Hi, As the project matures, and the community grows, I would like to revive an old discussion and suggest that we set some guidelines for contributing to the project's documentation. I would like to propose that we establish a minimal sub-set of rules, based on the official Python guidelines<https://devguide.python.org/documenting/#style-guide> which is the most widely used notation. This offers compatibility with existing tools for proofing and producing said documentation. The following rules should be considered: 1. H1 document title headers should be expressed by # with over-line (rows on top and bottom) of the text 2. Only ONE H1 header should allowed per document, ideally placed on top of the page. 3. H2 headers should be expressed by * with over-line 4. H2 header's text should be UNIQUE in per document basis 5. H3 headers should be expressed by a row of '=' 6. H4 headers should be expressed by a row of '-' 7. H3 and H4 headers have no limitation about naming. They can have similar names on the same document, as long as they have different parents. 8. H5 headers should be expressed by a row of '^' 9. H5 headers will be rendered in document body but not in menus on the navigation bar. 10. Do not use more than 5 level of heading 11. When writing guide, which are expected to be able to be readable by command line tools, it would be best practice to add long complicated tables, and UML diagrams in the bottom of the page and using internal references(auto-label). Please refer to the `tfm_sw_requirement.rst<https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/docs/getti…>` as an example 12. No special formatting should be allowed in Headers ( code, underline, strike-through etc ) 13. Long URLs and external references should be placed at the bottom of the page and referenced in the body of the document 14. New introduced terms and abbreviations should be added to Glossary and directly linked by the `:term:` notation across all documents using it. When something new, which is not covered is required, the rule should be first to follow the any reference to of an existing document, and the Python Documentation rules otherwise. Please let me know if you have any questions/objection or proposals or new rules you would like to consider. Any feedback is more than welcome. Minos

Re: [TF-M] Feature branch 'feature-isolation-level3' is created for related patches merging

Hi, Thank Tamas for the scenario, this is a good example. There were some queries and initial investigations before, which shows that some users want to protect the implementation of their services, and check if there are mechanisms to help on that. I think isolation level 3 is applicable to this scenario. /Ken From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Tamas Ban via TF-M Sent: Wednesday, October 21, 2020 7:26 PM To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] Feature branch 'feature-isolation-level3' is created for related patches merging Hi Andrej, the following scenario comes to my mind: * There is a product where secure services from different vendors are merged together and these are together make up the ARoT code. * There is a vendor who has a novel algorithm what he wants to protect against reverse engineering. * Image is delivered to the device in encrypted format.
