Secondary License.
#### 1.6. "Executable Form"
means any form of the work other than Source Code Form.
#### 1.7. "Larger Work"

### 2. License Grants and Conditions
#### 2.1. Grants
Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive
license:
* **(a)** under intellectual property rights (other than patent or trademark)
Licensable by such Contributor to use, reproduce, make available, modify,
display, perform, distribute, and otherwise exploit its Contributions, either
on an unmodified basis, with Modifications, or as part of a Larger Work; and
* **(b)** under Patent Claims of such Contributor to make, use, sell, offer for
sale, have made, import, and otherwise transfer either its Contributions or
its Contributor Version.
#### 2.2. Effective Date
The licenses granted in Section 2.1 with respect to any Contribution become
effective for each Contribution on the date the Contributor first distributes
such Contribution.
#### 2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under this
License. No additional rights or licenses will be implied from the distribution
or licensing of Covered Software under this License. Notwithstanding Section
2.1(b) above, no patent license is granted by a Contributor:
* **(a)** for any code that a Contributor has removed from Covered Software; or
* **(b)** for infringements caused by: **(i)** Your and any other third party's
modifications of Covered Software, or **(ii)** the combination of its
Contributions with other software (except as part of its Contributor
Version); or
* **(c)** under Patent Claims infringed by Covered Software in the absence of
its Contributions.
This License does not grant any rights in the trademarks, service marks, or
logos of any Contributor (except as may be necessary to comply with the notice
requirements in Section 3.4).
#### 2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to distribute
the Covered Software under a subsequent version of this License (see Section
10.2) or under the terms of a Secondary License (if permitted under the terms
of Section 3.3).
#### 2.5. Representation
Each Contributor represents that the Contributor believes its Contributions are
its original creation(s) or it has sufficient rights to grant the rights to its
Contributions conveyed by this License.
#### 2.6. Fair Use
This License is not intended to limit any rights You have under applicable
copyright doctrines of fair use, fair dealing, or other equivalents.
#### 2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
Section 2.1.
### 3. Responsibilities
#### 3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under the
terms of this License. You must inform recipients that the Source Code Form of
the Covered Software is governed by the terms of this License, and how they can
obtain a copy of this License. You may not attempt to alter or restrict the
recipients' rights in the Source Code Form.
#### 3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
* **(a)** such Covered Software must also be made available in Source Code
Form, as described in Section 3.1, and You must inform recipients of the
Executable Form how they can obtain a copy of such Source Code Form by
reasonable means in a timely manner, at a charge no more than the cost of
distribution to the recipient; and
* **(b)** You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the license
for the Executable Form does not attempt to limit or alter the recipients'
rights in the Source Code Form under this License.
#### 3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for the
Covered Software. If the Larger Work is a combination of Covered Software with
a work governed by one or more Secondary Licenses, and the Covered Software is
not Incompatible With Secondary Licenses, this License permits You to
additionally distribute such Covered Software under the terms of such Secondary
License(s), so that the recipient of the Larger Work may, at their option,
further distribute the Covered Software under the terms of either this License
or such Secondary License(s).
#### 3.4. Notices
You may not remove or alter the substance of any license notices (including
copyright notices, patent notices, disclaimers of warranty, or limitations of
liability) contained within the Source Code Form of the Covered Software,
except that You may alter any license notices to the extent required to remedy
known factual inaccuracies.
#### 3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support, indemnity
or liability obligations to one or more recipients of Covered Software.
However, You may do so only on Your own behalf, and not on behalf of any
Contributor. You must make it absolutely clear that any such warranty, support,
indemnity, or liability obligation is offered by You alone, and You hereby
agree to indemnify every Contributor for any liability incurred by such
Contributor as a result of warranty, support, indemnity or liability terms You
offer. You may include additional disclaimers of warranty and limitations of
liability specific to any jurisdiction.
### 4. Inability to Comply Due to Statute or Regulation
If it is impossible for You to comply with any of the terms of this License
with respect to some or all of the Covered Software due to statute, judicial
order, or regulation then You must: **(a)** comply with the terms of this
License to the maximum extent possible; and **(b)** describe the limitations
and the code they affect. Such description must be placed in a text file
included with all distributions of the Covered Software under this License.
Except to the extent prohibited by statute or regulation, such description must
be sufficiently detailed for a recipient of ordinary skill to be able to
understand it.
### 5. Termination
**5.1.** The rights granted under this License will terminate automatically if
You fail to comply with any of its terms. However, if You become compliant,
then the rights granted under this License from a particular Contributor are
reinstated **(a)** provisionally, unless and until such Contributor explicitly
and finally terminates Your grants, and **(b)** on an ongoing basis, if such
Contributor fails to notify You of the non-compliance by some reasonable means
prior to 60 days after You have come back into compliance. Moreover, Your
grants from a particular Contributor are reinstated on an ongoing basis if such
Contributor notifies You of the non-compliance by some reasonable means, this
is the first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after Your
receipt of the notice.
**5.2.** If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions, counter-claims, and
cross-claims) alleging that a Contributor Version directly or indirectly
infringes any patent, then the rights granted to You by any and all
Contributors for the Covered Software under Section 2.1 of this License shall
terminate.
**5.3.** In the event of termination under Sections 5.1 or 5.2 above, all end
user license agreements (excluding distributors and resellers) which have been
validly granted by You or Your distributors under this License prior to
termination shall survive termination.
### 6. Disclaimer of Warranty
> Covered Software is provided under this License on an "as is" basis, without
> warranty of any kind, either expressed, implied, or statutory, including,
> without limitation, warranties that the Covered Software is free of defects,
> merchantable, fit for a particular purpose or non-infringing. The entire risk
> as to the quality and performance of the Covered Software is with You.
> Should any Covered Software prove defective in any respect, You (not any
> Contributor) assume the cost of any necessary servicing, repair, or
> correction. This disclaimer of warranty constitutes an essential part of this
> License. No use of any Covered Software is authorized under this License
> except under this disclaimer.
### 7. Limitation of Liability
> Under no circumstances and under no legal theory, whether tort (including
> negligence), contract, or otherwise, shall any Contributor, or anyone who
> distributes Covered Software as permitted above, be liable to You for any
> direct, indirect, special, incidental, or consequential damages of any
> character including, without limitation, damages for lost profits, loss of
> goodwill, work stoppage, computer failure or malfunction, or any and all
> other commercial damages or losses, even if such party shall have been
> informed of the possibility of such damages. This limitation of liability
> shall not apply to liability for death or personal injury resulting from such
> party's negligence to the extent applicable law prohibits such limitation.
> Some jurisdictions do not allow the exclusion or limitation of incidental or
> consequential damages, so this exclusion and limitation may not apply to You.
### 8. Litigation
Any litigation relating to this License may be brought only in the courts of a
jurisdiction where the defendant maintains its principal place of business and
such litigation shall be governed by laws of that jurisdiction, without
reference to its conflict-of-law provisions. Nothing in this Section shall
prevent a party's ability to bring cross-claims or counter-claims.
### 9. Miscellaneous
This License represents the complete agreement concerning the subject matter
hereof. If any provision of this License is held to be unenforceable, such
provision shall be reformed only to the extent necessary to make it
enforceable. Any law or regulation which provides that the language of a
contract shall be construed against the drafter shall not be used to construe
this License against a Contributor.
### 10. Versions of the License
#### 10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in Section 10.3,
no one other than the license steward has the right to modify or publish new
versions of this License. Each version will be given a distinguishing version
number.
#### 10.2. Effect of New Versions
You may distribute the Covered Software under the terms of the version of the
License under which You originally received the Covered Software, or under the
terms of any subsequent version published by the license steward.
#### 10.3. Modified Versions
If you create software not governed by this License, and you want to create a
new license for such software, you may create and use a modified version of
this License if you rename the license and remove any references to the name of
the license steward (except to note that such modified license differs from
this License).
#### 10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
If You choose to distribute Source Code Form that is Incompatible With
Secondary Licenses under the terms of this version of the License, the notice
described in Exhibit B of this License must be attached.
### Exhibit A - Source Code Form License Notice
This Source Code Form is subject to the terms of the Mozilla Public
License, v. 2.0. If a copy of the MPL was not distributed with this file,
You can obtain one at http://mozilla.org/MPL/2.0/.
If it is not possible or desirable to put the notice in a particular file, then
You may include the notice in a location (such as a LICENSE file in a relevant
directory) where a recipient would be likely to look for such a notice.
You may add additional accurate notices of copyright ownership.
### Exhibit B - "Incompatible With Secondary Licenses" Notice
This Source Code Form is "Incompatible With Secondary Licenses", as defined
by the Mozilla Public License, v. 2.0.

# j6 UEFI headers
This is a set of headers for interacting with UEFI as a C++ EFI application. I
found the EDK2 headers seemed to be missing some definitions (or perhaps I just
hadn't found the right headers to include), and the GNU-EFI ones to be specific
to using GNU-EFI and tended to break when using clang to natively build an EFI
application.
I also hate the style of the standard headers, they should probably
come with a trigger warning for anyone who had to spend time doing Win32 COM
programming. So I've created my headers in a modern C++ style that is ABI
compatible, but doesn't attempt to be API compatible with other UEFI headers.
The UEFI protocol definition headers aren't directly included in the git repo,
but are generated from the `protos.yaml` file via the `generate_protos.py`
script. I've started with just the protocols I'm actually using in the [jsix][]
bootloader, but new protocols should be fairly simple to add. I'll happily
accept pull requests if you find this code useful.
