+This directory contains configuration files to ignore errors found in
+the build and test process which are known to the developers and for
+now can be safely ignored.
+
+To use:
+
+ $ cd zephyr
+ $ make SOMETHING >& result
+ $ scripts/filter-known-issues.py result
+
+It is included in the source tree so if anyone has to submit anything
+that triggers some kind of error that is a false positive, it can
+include the "ignore me" file, properly documented.
+
+Each file can contain one or more multiline Python regular expressions
+(https://docs.python.org/2/library/re.html#regular-expression-syntax)
+that match an error message. Multiple regular expressions are
+separated by comment blocks (that start with #). Note that an empty
+line still is considered part of the multiline regular expression.
+
+For example

+  that file path in a "variable" called 'filename' that later you can
+  match with (?P=filename) if you want to match multiple lines of the
+  same error message.
+
+Can get really twisted and interesting in terms of regexps; they are
+powerful, so start small :)

-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, sex characteristics, gender identity and expression,
-level of experience, education, socio-economic status, nationality, personal
-appearance, race, religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or
- advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic
- address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
- professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or
-reject comments, commits, code, wiki edits, issues, and other contributions
-that are not aligned to this Code of Conduct, or to ban temporarily or
-permanently any contributor for other behaviors that they deem inappropriate,
-threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported by contacting the project team at conduct@zephyrproject.org.
-Reports will be received by Kate Stewart (Linux Foundation) and Amy Occhialino
-(Intel). All complaints will be reviewed and investigated, and will result in a
-response that is deemed necessary and appropriate to the circumstances. The
-project team is obligated to maintain confidentiality with regard to the
-reporter of an incident.  Further details of specific enforcement policies may
-be posted separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good
-faith may face temporary or permanent repercussions as determined by other
-members of the project's leadership.

-standards and methods for submitting changes help reduce the chaos that can result
-from an active development community.
-
-This document briefly summarizes the full `Contribution
-Guidelines <http://docs.zephyrproject.org/latest/contribute/index.html>`_
-documentation.
-
-* Zephyr uses the permissive open source `Apache 2.0 license`_
-  that allows you to freely use, modify, distribute and sell your own products
-  that include Apache 2.0 licensed software.
-
-* There are some imported or reused components of the Zephyr project that
-  use other licensing and are clearly identified.
-
-* The Developer Certificate of Origin (DCO) process is followed to
-  ensure developers are following licensing criteria for their
-  contributions, and documented with a ``Signed-off-by`` line in commits.
-
-* Zephyr development workflow is supported on Linux, macOS, and Windows,
-  (with a few exceptions).
-
-* Source code for the project is maintained in the GitHub repo:
-  https://github.com/zephyrproject-rtos/zephyr
-
-* Issue and feature tracking is done using GitHub issues in this repo.
-
-* A Continuous Integration (CI) system runs on every Pull Request (PR)
-  to verify several aspects of the PR including Git commit formatting,
-  Coding Style, sanity checks builds, and documentation builds.
-
-* The `Zephyr devel mailing list`_ is a great place to engage with the
-  community, ask questions, discuss issues, and help each other.

-	  This option signifies that the target uses MCUboot as a bootloader,
-	  or in other words that the image is to be chain-loaded by MCUboot.
-	  This sets several required build system and Device Tree options in
-	  order for the image generated to be bootable using the MCUboot open

-
-	    * Setting ROM_START_OFFSET to a default value that allows space

-	    * Activating SW_VECTOR_RELAY_CLIENT on Cortex-M0
-	      (or Armv8-M baseline) targets with no built-in vector relocation
-	      mechanisms
-

+	S: Status, one of the following:
+	   Supported:	Someone is actually paid to look after this.
+	   Maintained:	Someone actually looks after it.
+	   Odd Fixes:	It has a maintainer but they don't have time to do
+			much other than throw the odd patch in. See below..
+	   Orphan:	No current maintainer [but maybe you could take the
+			role as you write your new code].
+	   Obsolete:	Old code. Something tagged obsolete generally means
+			it has been replaced by a better system and you
+			should be using that.
+	F: Files and directories with wildcard patterns.
+	   A trailing slash includes all files and subdirectory files.
+	   F:	drivers/net/	all files in and below drivers/net

+	K: Keyword perl extended regex pattern to match content in a

-
-The Zephyr Project is a scalable real-time operating system (RTOS) supporting
-multiple hardware architectures, optimized for resource constrained devices,
-and built with security in mind.
-
-The Zephyr OS is based on a small-footprint kernel designed for use on
-resource-constrained systems: from simple embedded environmental sensors and
-LED wearables to sophisticated smart watches and IoT wireless gateways.
-
-The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
-Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
-`supported boards`_.
-
-.. below included in doc/introduction/introduction.rst

-Getting Started
-***************
-
-Welcome to Zephyr! See the `Introduction to Zephyr`_ for a high-level overview,
-and the documentation's `Getting Started Guide`_ to start developing.

+ * @brief IRQ part of vector table for Quark SE Sensor Subsystem
+ *
+ * This file contains the IRQ part of the vector table. It is meant to be used
+ * for one of two cases:
+ *
+ * a) When software-managed ISRs (SW_ISR_TABLE) is enabled, and in that case it
+ * binds _IsrWrapper() to all the IRQ entries in the vector table.
+ *
+ * b) When the BSP is written so that device ISRs are installed directly in the
+ * vector table, they are enumerated here.
