update license terms

Browse source 
As of now, everything except the code imported
from FreeBSD is proprietary.  Of course, it won't
be like this for long, only until we have decided
which license we like to use.  The rationale is
that releasing everything under a copyleft license
later is always easier than doing so immediately
and then changing it afterwards.
Naturally, any changes made before this commit are
still subject to the terms of the CNPL.

An Act of War is any action of one country against any group either with
an intention to provoke a conflict or an action that occurs during a
declared war or during armed conflict between military forces of any
origin. This includes but is not limited to enforcing sanctions or
sieges, supplying armed forces, or profiting from the manufacture of
tools or weaponry used in military conflict.
An Adaptation is a work based upon the Work, or upon the Work and other
pre-existing works, such as a translation, adaptation, derivative work,
arrangement of music or other alterations of a literary or artistic
work, or phonogram or performance and includes cinematographic
adaptations or any other form in which the Work may be recast,
transformed, or adapted including in any form recognizably derived from
the original, except that a work that constitutes a Collection will not
be considered an Adaptation for the purpose of this License. For the
avoidance of doubt, where the Work is a musical work, performance or
phonogram, the synchronization of the Work in timed-relation with a
moving image ("synching") will be considered an Adaptation for the
purpose of this License. In addition, where the Work is designed to
output a neural network the output of the neural network will be
considered an Adaptation for the purpose of this license.
Bodily Harm is any physical hurt or injury to a person that interferes
with the health or comfort of the person and that is more than merely
transient or trifling in nature.
Distribute is to make available to the public the original and copies of

uses free from copyright or rights arising from limitations or
exceptions that are provided for in connection with the copyright
protection under copyright law or other applicable laws.
License Grant
=============
Subject to the terms and conditions of this License, Licensor hereby
grants You a worldwide, royalty-free, non-exclusive, perpetual (for the
duration of the applicable copyright) license to exercise the rights in
the Work as stated below:
To Reproduce the Work, to incorporate the Work into one or more
Collections, and to Reproduce the Work as incorporated in the
Collections
To create and Reproduce Adaptations provided that any such Adaptation,
including any translation in any medium, takes reasonable steps to
clearly label, demarcate or otherwise identify that changes were made to
the original Work. For example, a translation could be marked "The
original work was translated from English to Spanish," or a modification
could indicate "The original work has been modified."
To Distribute and Publicly Perform the Work including as incorporated in
Collections.
To Distribute and Publicly Perform Adaptations. The above rights may be
exercised in all media and formats whether now known or hereafter
devised. The above rights include the right to make such modifications
as are technically necessary to exercise the rights in other media and
formats. This License constitutes the entire agreement between the
parties with respect to the Work licensed here. There are no
understandings, agreements or representations with respect to the Work
not specified here. Licensor shall not be bound by any additional
provisions that may appear in any communication from You. This License
may not be modified without the mutual written agreement of the Licensor
and You. All rights not expressly granted by Licensor are hereby
reserved, including but not limited to the rights set forth in
Non-waivable Compulsory License Schemes, Waivable Compulsory License
Schemes, and Voluntary License Schemes in the restrictions.
Restrictions
============
The license granted in the license grant above is expressly made subject
to and limited by the following restrictions:
You may Distribute or Publicly Perform the Work only under the terms of
this License. You must include a copy of, or the Uniform Resource
Identifier (URI) for, this License with every copy of the Work You
Distribute or Publicly Perform. You may not offer or impose any terms on
the Work that restrict the terms of this License or the ability of the
recipient of the Work to exercise the rights granted to that recipient
under the terms of the License. You may not sublicense the Work. You
must keep intact all notices that refer to this License and to the
disclaimer of warranties with every copy of the Work You Distribute or
Publicly Perform. When You Distribute or Publicly Perform the Work, You
may not impose any effective technological measures on the Work that
restrict the ability of a recipient of the Work from You to exercise the
rights granted to that recipient under the terms of the License. This
Section applies to the Work as incorporated in a Collection, but this
does not require the Collection apart from the Work itself to be made
subject to the terms of this License. If You create a Collection, upon
notice from any Licensor You must, to the extent practicable, remove
from the Collection any credit as requested. If You create an
Adaptation, upon notice from any Licensor You must, to the extent
practicable, remove from the Adaptation any credit as requested.
Commercial Restrictions
-----------------------
You may not exercise any of the rights granted to You in the above
section in any manner that is primarily intended for or directed toward
commercial advantage or private monetary compensation unless you meet
the following requirements.
i. You are a worker-owned business or worker-owned collective.
ii. after tax, all financial gain, surplus, profits and benefits
produced by the business or collective are distributed among the
worker-owners unless a set amount is to be allocated towards
community projects as decided by a previously-established consensus
agreement between the worker-owners where all worker-owners agreed.
iii. You are not using such rights on behalf of a business other than
those specified in (i) or (ii) above, nor are using such rights as
a proxy on behalf of a business with the intent to circumvent the
aforementioned restrictions on such a business.
The exchange of the Work for other copyrighted works by means of digital
file-sharing or otherwise shall not be considered to be intended for or
directed toward commercial advantage or private monetary compensation,
provided there is no payment of any monetary compensation in connection
with the exchange of copyrighted works.
If the Work meets the definition of Software, You may exercise the
rights granted in the license grant only if You provide a copy of the
corresponding Source Code from which the Work was derived in digital
form, or You provide a URI for the corresponding Source Code of the
Work, to any recipients upon request.
If the Work is used as or for a Network Service, You may exercise the
rights granted in the license grant only if You provide a copy of the
corresponding Source Code from which the Work was derived in digital
form, or You provide a URI for the corresponding Source Code to the
Work, to any recipients of the data served or modified by the Web
Service.
Any use by a business that is privately owned and managed, and that
seeks to generate profit from the labor of employees paid by salary or
other wages, is not permitted under this license.
You may exercise the rights granted in the license grant for any
purposes only if:
i. You do not use the Work for the purpose of inflicting Bodily Harm
on human beings (subject to criminal prosecution or otherwise)
outside of providing medical aid or undergoing a voluntary
procedure under no form of Coercion.
ii. You do not use the Work for the purpose of Surveilling or tracking
individuals for financial gain.
iii. You do not use the Work in an Act of War.
iv. You do not use the Work for the purpose of supporting or profiting
from an Act of War.
v. You do not use the Work for the purpose of Incarceration.
vi. You do not use the Work for the purpose of extracting, processing,
or refining, oil, gas, or coal. Or to in any other way to
deliberately pollute the environment as a byproduct of
manufacturing or irresponsible disposal of hazardous materials.
vii. You do not use the Work for the purpose of expediting,
coordinating, or facilitating paid work undertaken by individuals
under the age of 12 years.
viii. You do not use the Work to either Discriminate or spread Hate
Speech on the basis of sex, sexual orientation, gender identity,
race, age, disability, color, national origin, religion, caste, or
lower economic status.
If You Distribute, or Publicly Perform the Work or any Adaptations or
Collections, You must, unless a request has been made by any Licensor to
remove credit from a Collection or Adaptation, keep intact all copyright
notices for the Work and provide, reasonable to the medium or means You
are utilizing:
i. the name of the Original Author (or pseudonym, if applicable) if
supplied, and/or if the Original Author and/or Licensor designate
another party or parties (e.g., a sponsor institute, publishing
entity, journal) for attribution ("Attribution Parties") in
Licensor's copyright notice, terms of service or by other
reasonable means, the name of such party or parties;
ii. the title of the Work if supplied;
iii. to the extent reasonably practicable, the URI, if any, that

Work; and,
iv. in the case of an Adaptation, a credit identifying the use of the
Work in the Adaptation (e.g., "French translation of the Work by
Original Author," or "Screenplay based on original Work by Original
Author").
If any Licensor has sent notice to request removing credit, You must, to
the extent practicable, remove any credit as requested. The credit
required by this Section may be implemented in any reasonable manner;
provided, however, that in the case of an Adaptation or Collection, at a
minimum such credit will appear, if a credit for all contributing
authors of the Adaptation or Collection appears, then as part of these
credits and in a manner at least as prominent as the credits for the
other contributing authors. For the avoidance of doubt, You may only use
the credit required by this Section for the purpose of attribution in
the manner set out above and, by exercising Your rights under this
License, You may not implicitly or explicitly assert or imply any
connection with, sponsorship or endorsement by the Original Author,
Licensor and/or Attribution Parties, as appropriate, of You or Your use
of the Work, without the separate, express prior written permission of
the Original Author, Licensor and/or Attribution Parties.
Non-waivable Compulsory License Schemes. In those jurisdictions in which
the right to collect royalties through any statutory or compulsory
licensing scheme cannot be waived, the Licensor reserves the exclusive
right to collect such royalties for any exercise by You of the rights
granted under this License
Waivable Compulsory License Schemes. In those jurisdictions in which the
right to collect royalties through any statutory or compulsory licensing
scheme can be waived, the Licensor reserves the exclusive right to
collect such royalties for any exercise by You of the rights granted
under this License if Your exercise of such rights is for a purpose or
use which is otherwise than noncommercial as permitted under Commercial
Restrictions and otherwise waives the right to collect royalties through
any statutory or compulsory licensing scheme.
Voluntary License Schemes. The Licensor reserves the right to collect
royalties, whether individually or, in the event that the Licensor is a
member of a collecting society that administers voluntary licensing
schemes, via that society, from any exercise by You of the rights
granted under this License that is for a purpose or use which is
otherwise than noncommercial as permitted under the license grant.
Except as otherwise agreed in writing by the Licensor or as may be
otherwise permitted by applicable law, if You Reproduce, Distribute or
Publicly Perform the Work either by itself or as part of any Adaptations
or Collections, You must not distort, mutilate, modify or take other
derogatory action in relation to the Work which would be prejudicial to
the Original Author's honor or reputation. Licensor agrees that in those
jurisdictions (e.g. Japan), in which any exercise of the right granted
in the license grant of this License (the right to make Adaptations)
would be deemed to be a distortion, mutilation, modification or other
derogatory action prejudicial to the Original Author's honor and
reputation, the Licensor will waive or not assert, as appropriate, this
Section, to the fullest extent permitted by the applicable national law,
to enable You to reasonably exercise Your right under the license grant
of this License (right to make Adaptations) but not otherwise.
Do not make any legal claim against anyone accusing the Work, with or
without changes, alone or with other works, of infringing any patent
claim.
Representations Warranties and Disclaimer
=========================================
UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE
EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
Limitation on Liability
=======================
EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE LAW, IN NO EVENT WILL
LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY SPECIAL,
INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING OUT OF
THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN ADVISED
OF THE POSSIBILITY OF SUCH DAMAGES.
Termination
===========
This License and the rights granted hereunder will terminate
automatically upon any breach by You of the terms of this License.
Individuals or entities who have received Adaptations or Collections
from You under this License, however, will not have their licenses
terminated provided such individuals or entities remain in full
compliance with those licenses. The Sections on definitions, fair
dealing rights, representations, warranties, and disclaimer, limitation
on liability, termination, and revised license versions will survive any
termination of this License.
Subject to the above terms and conditions, the license granted here is
perpetual (for the duration of the applicable copyright in the Work).
Notwithstanding the above, Licensor reserves the right to release the
Work under different license terms or to stop distributing the Work at
any time; provided, however that any such election will not serve to
withdraw this License (or any other license that has been, or is
required to be, granted under the terms of this License), and this
License will continue in full force and effect unless terminated as
stated above.
Revised License Versions
========================
This License may receive future revisions in the original spirit of the
license intended to strengthen This License. Each version of This
License has an incrementing version number.
Unless otherwise specified like in the below subsection The Licensor has
only granted this current version of This License for The Work. In this
case future revisions do not apply.
The Licensor may specify that the latest available revision of This
License be used for The Work by either explicitly writing so or by
suffixing the License URI with a "+" symbol.
The Licensor may specify that The Work is also available under the terms
of This License's current revision as well as specific future revisions.
The Licensor may do this by writing it explicitly or suffixing the
License URI with any additional version numbers each separated by a
comma.
Miscellaneous
=============
Each time You Distribute or Publicly Perform the Work or a Collection,
the Licensor offers to the recipient a license to the Work on the same
terms and conditions as the license granted to You under this License.
Each time You Distribute or Publicly Perform an Adaptation, Licensor
offers to the recipient a license to the original Work on the same terms
and conditions as the license granted to You under this License.
If the Work is classified as Software, each time You Distribute or
Publicly Perform an Adaptation, Licensor offers to the recipient a copy
and/or URI of the corresponding Source Code on the same terms and
conditions as the license granted to You under this License.
If the Work is used as a Network Service, each time You Distribute or
Publicly Perform an Adaptation, or serve data derived from the Software,
the Licensor offers to any recipients of the data a copy and/or URI of
the corresponding Source Code on the same terms and conditions as the
license granted to You under this License.
If any provision of this License is invalid or unenforceable under
applicable law, it shall not affect the validity or enforceability of
the remainder of the terms of this License, and without further action
by the parties to this agreement, such provision shall be reformed to
the minimum extent necessary to make such provision valid and
enforceable.
No term or provision of this License shall be deemed waived and no
breach consented to unless such waiver or consent shall be in writing
and signed by the party to be charged with such waiver or consent.
This License constitutes the entire agreement between the parties with
respect to the Work licensed here. There are no understandings,
agreements or representations with respect to the Work not specified
here. Licensor shall not be bound by any additional provisions that may
appear in any communication from You. This License may not be modified
without the mutual written agreement of the Licensor and You.
The rights granted under, and the subject matter referenced, in this
License were drafted utilizing the terminology of the Berne Convention
for the Protection of Literary and Artistic Works (as amended on
September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 and
the Universal Copyright Convention (as revised on July 24, 1971). These
rights and subject matter take effect in the relevant jurisdiction in
which the License terms are sought to be enforced according to the
corresponding provisions of the implementation of those treaty
provisions in the applicable national law. If the standard suite of
rights granted under applicable copyright law includes additional rights
not granted under this License, such additional rights are deemed to be
included in the License; this License is not intended to restrict the
license of any rights under applicable law.

There isn't much to see here yet -- only the most basic boot routine is
implemented at the moment.

## Building

The kernel compiles to an x86-64 ELF file that implements the GNU

amd64 support is currently being implemented, and will be the main focus for
further development.
32-bit platforms are likely to be abandoned all together in the near future,
simply due to the fact that the additional housekeeping for maintaining correct
memory mappings in this constrained address space has turned out to be way too
much as to be feasible for the current size of this project.
i386 support is pretty much dead, simply due to the fact that the additional
housekeeping for maintaining correct memory mappings in this constrained address
space has turned out to be way too much as to be feasible for the current size
of this project. Furthermore, pretty much every desktop CPU manufactured since
around 2005 supports 64-bit anyway.
### Required Tools
- A POSIX operating system (use WSL if you find yourself in the unfortunate
situation of running Windows)
- CMake >= 3.14
- clang, with support for the `i686-none` target
- clang, with support for the `x86_64-pc-none-elf` target
