+
+
+### 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.

 # Design / WIP notes
 
-## Bootloader / UEFI
+## TODO
 
-* What is the interface between the UEFI boot portion and the kernel?
+- Paging manager
-  * Allocate pages, use UEFI reserved mapping types (0x70000000 - 0x7fffffff)
+  - Copy-on-write pages
-  * Passing memory map: Allocate earliest pages and fill with UEFI's memory map
+  - Better page-allocation model?
-    stuctures?
+- Allow for more than one IOAPIC in ACPI module
+  - The objects get created, but GSI lookup only uses the one at index 0
+- mark kernel memory pages global
+- Serial out based on circular/bip biffer and interrupts, not spinning on
+  `write_ready()`
+- Split out more code into kutil for testing
+- AHCI / MSI interrupts on Vbox break?
+- FXSAVE to save XMM registers.
+  - optimization using #NM (0x7) to detect SSE usage
+- Clean up of process memory maps
+- Better stack tracer
+- Bootloader rewrite
+  - C++ and sharing library code for ELF, initrd, etc
+  - Parse initrd and pre-load certain ELF images, eg the process loader process?
+  - Do initial memory bootstrap?
+- Calling global ctors
+- Device Tree
+  - Actual serial driver
+  - Disk driver
+    - File system
+- Multiprocessing
+  - Fast syscalls using syscall/sysret
 
+### Build
+
+- Clean up build generator and its templates
+  - More robust objects to represent modules & targets to pass to templates
+  - Read project setup from a simple JSON/TOML/etc
+  - Better compartmentalizing when doing template inheritance
+- Move to LLD as sysroot linker

-# popcorn: A toy microkernel x64 UEFI OS 
+# jsix: A toy OS kernel
 
-**popcorn** is a hobby OS for x64 UEFI environments to play with building a
+**jsix** is the kernel for the hobby OS that I am currently building. It's
-microkenerl architecture. It's far from finished, or even being usable - for
+far from finished, or even being usable. Instead, it's a sandbox for me to play
-now, it's a sandbox for me to explore the UEFI architecture, microkernels, and
+with kernel-level code and explore architectures.
-OS-related concepts that I want to play with.
+
+The design goals of the project are:
+
+* Modernity - I'm not interested in designing for legacy systems, or running on
+  all hardware out there. My target is only 64 bit architecutres, and modern
+  commodity hardware. Currently that means x64 systems with Nehalem or newer
+  CPUs and UEFI firmware. Eventually I'd like to work on an AArch64 port,
+  partly to force myself to factor out the architecture-dependent pieces of the
+  code base.
+
+* Modularity - I'd like to pull as much of the system out into separate
+  processes as possible, in the microkernel fashion. A sub-goal of this is to
+  explore where the bottlenecks of such a microkernel are now, and whether
+  eschewing legacy hardware will let me design a system that's less bogged down
+  by the traditional microkernel problems. Given that there are no processes
+  yet, the kernel is monolithic by default.
+
+* Exploration - I'm really mostly doing this to have fun learning and exploring
+  modern OS development. Modular design may be tossed out (hopefully
+  temporarily) in some places to allow me to play around with the related
+  hardware.
+
+A note on the name: This kernel was originally named Popcorn, but I have since
+discovered that the Popcorn Linux project is also developing a kernel with that
+name, started around the same time as this project. So I've renamed this kernel
+jsix (Always styled _jsix_ or `j6`, never capitalized) as an homage to L4, xv6,
+and my wonderful wife.
+
+## Building
+
+jsix uses the [Ninja][] build tool, and generates the build files for it with a
+custom tool called [Bonnibel][]. Bonnibel can be installed with [Cargo][], or
+downloaded as a prebuilt binary from its Github repository.
+
+[Ninja]:    https://ninja-build.org
+[Bonnibel]: https://github.com/justinian/bonnibel
+[Cargo]:    https://crates.io/crates/bonnibel
+
+Requrirements:
+
+* bonnibel
+* ninja
+* clang
+* nasm
+* mtools
+* curl for downloading the toolchain
+
+### Setting up the cross toolchain
+
+Running `pb sync` will download and unpack the toolchain into `sysroot`. 
+
+#### Compiling the toolchain yourself
+
+If you have `clang` and `curl` installed, runing the `scripts/build_sysroot.sh`
+script will download and build a LLVM toolchain configured for building jsix
+host binaries.
+
+### Building and running jsix
+
+Once the toolchain has been set up, running Bonnibel's `pb init` command will
+set up the build configuration, and `pb build` will actually run the build.  If
+you have `qemu-system-x86_64` installed, the `qemu.sh` script will to run jsix
+in QEMU `-nographic` mode.
+
+I personally run this either from a real debian amd64 testing/buster machine or
+a windows WSL debian testing/buster installation. The following should be
+enough to set up such a system to build the kernel:
+
+    sudo apt install qemu-system-x86 nasm clang-6.0 mtools curl
+    sudo update-alternatives /usr/bin/clang clang /usr/bin/clang-6.0 1000
+    sudo update-alternatives /usr/bin/clang++ clang++ /usr/bin/clang++-6.0 1000
+	curl -L -o pb https://github.com/justinian/bonnibel/releases/download/2.0.0/pb_linux_amd64 && chmod a+x pb
