requirements: add Events system and software requirements

Add a System requirement (ZEP-SYRS-27) describing the Zephyr event object synchronization mechanism, and a new Events software requirements document (ZEP-SRS-27-*) refining it into 15 atomic, implementation-free requirements covering event object definition, delivering events (post/set/set-masked/clear), and waiting for events (any/all, timeout, reset, reported results).

The requirements reflect the currently implemented k_event API behavior following the Route 3s approach. All software requirements link to the ZEP-SYRS-27 system parent, and the new document is registered in the software requirements index. UIDs were generated with “strictdoc manage auto-uid”.

Zephyr Project Requirements

This repository contains a preliminary work on the Zephyr Project requirements.

The requirements are captured using StrictDoc.

See the Zephyr Safety Working Group Wiki for information on connecting to the team.

The guidelines around writing requirements are located here: Safety Requirements

Deployed Documentation

The requirements documentation is available online at: https://zephyrproject-rtos.github.io/reqmgmt

System requirements

The requirements shall be browsable and editable on all major operating systems that have Python 3.7+.

Getting started

To install the requirements management tool:

pip install strictdoc

To generate the requirements documentation in HTML format:

strictdoc export .

To browse/edit the requirements using StrictDoc’s web interface:

strictdoc server .

To generate uid’s for new written requirements use the command:

strictdoc manage auto-uid .
