Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. {one line to give the program's name and a brief idea of what it does.} Copyright (C) {year} {name of author} This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: {project} Copyright (C) {year} {fullname} This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.

(WebAssembly) QtRVSim is experimentally available for [WebAssembly](https://webassembly.org/) and it can be run in most browsers without installation. **[QtRVSim online](https://comparch.edu.cvut.cz/qtrvsim/app)** **Note, that WebAssembly version is experimental.** Please, report any difficulties via [GitHub issues](https://github.com/cvut/qtrvsim/issues/new). ## Build and packages [![Packaging status](https://repology.org/badge/vertical-allrepos/qtrvsim.svg)](https://repology.org/project/qtrvsim/versions) [![build result](https://build.opensuse.org/projects/home:jdupak/packages/qtrvsim/badge.svg?type=default)](https://build.opensuse.org/package/show/home:jdupak/qtrvsim) ### Build Dependencies - Qt 5 (minimal tested version is 5.9.5), experimental support of Qt 6 - elfutils (optional; libelf works too but there can be some problems) ### Quick Compilation on Linux On Linux, you can use a wrapper Makefile and run `make` in the project root directory. It will create a build directory and run CMake in it. Available targets are: `release` (default) and `debug`. Note for packagers: This Makefile is deleted by CMake when source archive is created to avoid any ambiguity. Packages should invoke CMake directly. ### General Compilation ```shell cmake -DCMAKE_BUILD_TYPE=Release /path/to/qtrvsim make ``` Where `/path/to/qtrvsim` is path to this project root. The built binaries are to be found in the directory `target`in the build directory (the one, where cmake was called). `-DCMAKE_BUILD_TYPE=Debug` builds development version including sanitizers. If no build type is supplied, `Debug` is the default. ### Building from source on macOS Install the latest version of **Xcode** from the App Store. Then open a terminal and execute `xcode-select --install` to install Command Line Tools. Then open Xcode, accept the license agreement and wait for it to install any additional components. After you finally see the "Welcome to Xcode" screen, from the top bar choose `Xcode -> Preferences -> Locations -> Command Line Tools` and select an SDK version. Install [Homebrew](https://brew.sh/) and use it to install Qt. (macOS builds must use the bundled libelf) ```shell brew install qt ``` Now build the project the same way as in general compilation ([above](#general-compilation)). ### Download Binary Packages - [https://github.com/cvut/qtrvsim/releases](https://github.com/cvut/qtrvsim/releases) - archives with Windows and generic GNU/Linux binaries - [https://build.opensuse.org/repositories/home:jdupak/qtrvsim](https://build.opensuse.org/repositories/home:jdupak/qtrvsim) - [https://software.opensuse.org/download.html?project=home%3Ajdupak&package=qtrvsim](https://software.opensuse.org/download.html?project=home%3Ajdupak&package=qtrvsim) - Open Build Service binary packages - [https://launchpad.net/~qtrvsimteam/+archive/ubuntu/ppa](https://launchpad.net/~qtrvsimteam/+archive/ubuntu/ppa) - Ubuntu PPA archive ```bash sudo add-apt-repository ppa:qtrvsimteam/ppa sudo apt-get update sudo apt-get install qtrvsim ``` ### Nix package QtRVSim provides a Nix package as a part of the repository. You can build and install it by a command bellow. Updates have to be done manually by checking out the git. NIXPKGS package is in PR phase. ```shell nix-env -if . ``` ### Tests Tests are managed by CTest (part of CMake). To build and run all tests, use this commands: ```bash cmake -DCMAKE_BUILD_TYPE=Release /path/to/QtRVSim make ctest ``` ## Documentation Main documentation is provided in this README and in subdirectories [`docs/user`](docs/user) and [`docs/developer`](docs/developer). The project was developed and extended as theses of Karel KoÄí, Jakub Dupak and Max Hollmann. See section [Resources and Publications](#resources-and-publications) for links and references. ## Accepted Binary Formats The simulator accepts ELF statically linked executables compiled for RISC-V target (`--march=rv64g`). The simulator will automatically select endianness based on the ELF file header. Simulation will execute as XLEN=32 or XLEN=32 according to the ELF file header. - 64-bit RISC-V ISA RV64IM and 32-bit RV32IM ELF executables are supported. - Compressed instructions are not yet supported. You can use compile the code for simulation using specialized RISC-V GCC/Binutils toolchain (`riscv32-elf`) or using unified Clang/LLVM toolchain with [LLD](https://lld.llvm.org/). If you have Clang installed, you don't need any additional tools. Clang can be used on Linux, Windows, macOS and others... ### LLVM toolchain usage ```shell clang --target=riscv32 -march=rv32g -nostdlib -static -fuse-ld=lld test.S -o test llvm-objdump -S test ``` ### GNU toolchain usage ```shell riscv32-elf-as test.S -o test.o riscv32-elf-ld test.o -o test riscv32-elf-objdump -S test ``` or ```shell riscv32-elf-gcc test.S -o test riscv32-elf-objdump -S test ``` ### GNU 64-bit toolchain use for RV32I target Multilib supporting 64-bit embedded toolchain can be used for to build executable ```shell riscv64-unknown-elf-gcc -march=rv32i -mabi=ilp32 -nostdlib -o test test.c crt0local.S -lgcc ``` The global pointer and stack has to be set to setup runtime C code conformant environment. When no other C library is used then next simple `crt0local.S` can be used.
example code ```asm /* minimal replacement of crt0.o which is else provided by C library */ .globl main .globl _start .globl __start .option norelax .text __start: _start: .option push .option norelax la gp, __global_pointer$ .option pop la sp, __stack_end addi a0, zero, 0 addi a1, zero, 0 jal main quit: addi a0, zero, 0 addi a7, zero, 93 /* SYS_exit */ ecall loop: ebreak beq zero, zero, loop .bss __stack_start: .skip 4096 __stack_end: .end _start ```
## Integrated Assembler Basic integrated assembler is included in the simulator. Small subset of [GNU assembler](https://sourceware.org/binutils/docs/as/) directives is recognized as well. Next directives are recognized: `.word`, `.orig`, `.set` /`.equ`, `.ascii` and `.asciz`. Some other directives are simply ignored: `.data`, `.text`, `.globl`, `.end` and `.ent`. This allows to write code which can be compiled by both - integrated and full-featured assembler. Addresses are assigned to labels/symbols which are stored in symbol table. Addition, subtraction, multiplication, divide and bitwise and or are recognized. ## Support to call external make utility The action "Build executable by external make" call "make" program. If the action is invoked, and some source editors selected in main windows tabs then the "make" is started in the corresponding directory. Else directory of last selected editor is chosen. If no editor is open then directory of last loaded ELF executable are used as "make" start path. If even that is not an option then default directory when the emulator has been started is used. ## Advanced functionalities ### Peripherals
Emuated LCD, knobs, buttons, serial port, timer... The simulator implements emulation of two peripherals for now. The first is simple serial port (UART). It support transmission (Tx) and reception (Rx). Receiver status register (`SERP_RX_ST_REG`) implements two bits. Read-only bit 0 (`SERP_RX_ST_REG_READY`) is set to one if there is unread character available in the receiver data register (`SERP_RX_DATA_REG`). The bit 1 (`SERP_RX_ST_REG_IE`) can be written to 1 to enable interrupt request when unread character is available. The transmitter status register (`SERP_TX_ST_REG`) bit 0 (SERP_TX_ST_REG_READY) signals by value 1 that UART is ready and can accept next character to be sent. The bit 1 (`SERP_TX_ST_REG_IE`) enables generation of interrupt. The register `SERP_TX_DATA_REG` is actual Tx buffer. The LSB byte of written word is transmitted to the terminal window. Definition of peripheral base address and registers offsets (`_o`) and individual fields masks (`_m`) follows ``` #define SERIAL_PORT_BASE 0xffffc000 #define SERP_RX_ST_REG_o 0x00 #define SERP_RX_ST_REG_READY_m 0x1 #define SERP_RX_ST_REG_IE_m 0x2 #define SERP_RX_DATA_REG_o 0x04 #define SERP_TX_ST_REG_o 0x08 #define SERP_TX_ST_REG_READY_m 0x1 #define SERP_TX_ST_REG_IE_m 0x2 #define SERP_TX_DATA_REG_o 0x0c ``` The UART registers region is mirrored on the address 0xffff0000 to enable use of programs initially written for [SPIM](http://spimsimulator.sourceforge.net/) or [MARS](http://courses.missouristate.edu/KenVollmar/MARS/) emulators. The another peripheral allows to set three byte values concatenated to single word (read-only `KNOBS_8BIT` register) from user panel set by knobs and display one word in hexadecimal, decimal and binary format (`LED_LINE` register). There are two other words writable which control color of RGB LED 1 and 2 (registers `LED_RGB1` and `LED_RGB2`). ``` #define SPILED_REG_BASE 0xffffc100 #define SPILED_REG_LED_LINE_o 0x004 #define SPILED_REG_LED_RGB1_o 0x010 #define SPILED_REG_LED_RGB2_o 0x014 #define SPILED_REG_LED_KBDWR_DIRECT_o 0x018 #define SPILED_REG_KBDRD_KNOBS_DIRECT_o 0x020 #define SPILED_REG_KNOBS_8BIT_o 0x024 ``` The simple 16-bit per pixel (RGB565) framebuffer and LCD are implemented. The framebuffer is mapped into range starting at `LCD_FB_START` address. The display size is 480 x 320 pixel. Pixel format RGB565 expect red component in bits 11.. 15, green component in bits 5..10 and blue component in bits 0..4. ``` #define LCD_FB_START 0xffe00000 #define LCD_FB_END 0xffe4afff ``` The basic implementation of RISC-V Advanced Core Local Interruptor is implemented with basic support for - Machine-level Timer Device (MTIMER) - Machine-level Software Interrupt Device (MSWI) ``` #define ACLINT_MSWI 0xfffd0000 // core 0 machine SW interrupt request #define ACLINT_MTIMECMP 0xfffd4000 // core 0 compare value #define ACLINT_MTIME 0xfffdbff8 // timer base 10 MHz #define ACLINT_SSWI 0xfffd0000 // core 0 system SW interrupt request ``` More information about ACLINT can be found in [RISC-V Advanced Core Local Interruptor Specification](https://github.com/riscv/riscv-aclint/blob/main/riscv-aclint.adoc).
### Interrupts and Control and Status Registers
Implemented CSR registers and their usage List of interrupt sources: | Irq number | mie / mip Bit | Source | |-----------:|-----------------:|:---------------------------------------------| | 3 | 3 | Machine software interrupt request | | 7 | 7 | Machine timer interrupt | | 16 | 16 | There is received character ready to be read | | 17 | 17 | Serial port ready to accept character to Tx | Following Control Status registers are recognized | Number | Name | Description | |-------:|:-----------|:--------------------------------------------------------------------| | 0x300 | mstatus | Machine status register. | | 0x304 | mie | Machine interrupt-enable register. | | 0x305 | mtvec | Machine trap-handler base address. | | 0x340 | mscratch | Scratch register for machine trap handlers. | | 0x341 | mepc | Machine exception program counter. | | 0x342 | mcause | Machine trap cause. | | 0x343 | mtval | Machine bad address or instruction. | | 0x344 | mip | Machine interrupt pending. | | 0x34A | mtinsr | Machine trap instruction (transformed). | | 0x34B | mtval2 | Machine bad guest physical address. | | 0xB00 | mcycle | Machine cycle counter. | | 0xB02 | minstret | Machine instructions-retired counter. | | 0xF11 | mvendorid | Vendor ID. | | 0xF12 | marchid | Architecture ID. | | 0xF13 | mimpid | Implementation ID. | | 0xF14 | mhardid | Hardware thread ID. | `csrr`, `csrw`, `csrrs` , `csrrs` and `csrrw` are used to copy and exchange value from/to RISC-V control status registers. Sequence to enable serial port receive interrupt: Decide location of interrupt service routine the first. The address of the common trap handler is defined by `mtvec` register and then PC is set to this address when exception or interrupt is accepted. Enable bit 16 in the machine Interrupt-Enable register (`mie`). Ensure that bit 3 (`mstatus.mie` - machine global interrupt-enable) of Machine Status register is set to one. Enable interrupt in the receiver status register (bit 1 of `SERP_RX_ST_REG`). Write character to the terminal. It should be immediately consumed by the serial port receiver if interrupt is enabled in `SERP_RX_ST_REG`. CPU should report interrupt exception and when it propagates to the execution phase `PC` is set to the interrupt routine start address.
### System Calls Support
Syscall table and documentation The emulator includes support for a few Linux kernel system calls. The RV32G ilp32 ABI is used. | Register | use on input | use on output | Calling Convention | |:-----------------------------------|:----------------------|:----------------|:-------------------------------| | zero (x0) | — | - | Hard-wired zero | | ra (x1) | — | (preserved) | Return address | | sp (x2) | — | (callee saved) | Stack pointer | | gp (x3) | — | (preserved) | Global pointer | | tp (x4) | — | (preserved) | Thread pointer | | t0 .. t2 (x5 .. x7) | — | - | Temporaries | | s0/fp (x8) | — | (callee saved) | Saved register/frame pointer | | s1 (x9) | — | (callee saved) | Saved register | | a0 (x10) | 1st syscall argument | return value | Function argument/return value | | a1 (x11) | 2nd syscall argument | - | Function argument/return value | | a2 .. a5 (x12 .. x15) | syscall arguments | - | Function arguments | | a6 (x16) | - | - | Function arguments | | a7 (x17) | syscall number | - | Function arguments | | s2 .. s11 (x18 .. x27) | — | (callee saved) | Saved registers | | t3 .. t6 (x28 .. x31) | — | - | Temporaries | The all system call input arguments are passed in register. Supported syscalls: #### void [exit](http://man7.org/linux/man-pages/man2/exit.2.html)(int status) __NR_exit (93) Stop/end execution of the program. The argument is exit status code, zero means OK, other values informs about error. #### ssize_t [read](http://man7.org/linux/man-pages/man2/read.2.html)(int fd, void *buf, size_t count) __NR_read (63) Read `count` bytes from open file descriptor `fd`. The emulator maps file descriptors 0, 1 and 2 to the internal terminal/console emulator. They can be used without `open` call. If there are no more characters to read from the console, newline is appended. At most the count bytes read are stored to the memory location specified by `buf` argument. Actual number of read bytes is returned. #### ssize_t [write](http://man7.org/linux/man-pages/man2/write.2.html)(int fd, const void *buf, size_t count) __NR_write (64) Write `count` bytes from memory location `buf` to the open file descriptor `fd`. The same about console for file handles 0, 1 and 2 is valid as for `read`. #### int [close](http://man7.org/linux/man-pages/man2/close.2.html)(int fd) __NR_close (57) Close file associated to descriptor `fd` and release descriptor. #### int [openat](http://man7.org/linux/man-pages/man2/open.2.html)(int dirfd, const char *pathname, int flags, mode_t mode) __NR_openat (56) Open file and associate it with the first unused file descriptor number and return that number. If the option `OS Emulation`->`Filesystem root` is not empty then the file path `pathname` received from emulated environment is appended to the path specified by `Filesystem root`. The host filesystem is protected against attempt to traverse to random directory by use of `..` path elements. If the root is not specified then all open files are targetted to the emulated terminal. Only `TARGET_AT_FDCWD` (`dirfd` = -100) mode is supported. #### void * [brk](http://man7.org/linux/man-pages/man2/brk.2.html)(void *addr) __NR_brk (214) Set end of the area used by standard heap after end of the program data/bss. The syscall is emulated by dummy implementation. Whole address space up to 0xffff0000 is backuped by automatically attached RAM. #### int [ftruncate](http://man7.org/linux/man-pages/man2/ftruncate.2.html)(int fd, off_t length) __NR_truncate (46) Set length of the open file specified by `fd` to the new `length`.

## Limitations of the Implementation - See list of currently supported instructions. ### QtRvSim limitations * Only very minimal support for privileged instruction is implemented for now (mret). * Only machine mode and minimal subset of machine CSRs is implemented. * TLB and virtual memory are not implemented. * No floating point support * Memory access stall (stalling execution because of cache miss would be pretty annoying for users so difference between cache and memory is just in collected statistics) * Only limited support for interrupts and exceptions. When `ecall` instruction is recognized, small subset of the Linux kernel system calls can be emulated or simulator can be configured to continue by trap handler on `mtvec` address. ### List of Currently Supported Instructions - **RV32I**: - **LOAD**: `lw, lh, lb, lwu, lhu, lbu` - **STORE**: `sw, sh, sb, swu, shu, sbu` - **OP**: `add, sub, sll, slt, sltu, xor, srl, sra, or, and` - **MISC-MEM**: `fence, fence.i` - **OP-IMM**: `addi, sll, slti, sltiu, xori, srli, srai, ori, andi, auipc, lui` - **BRANCH**: `beq, bne, btl, bge, bltu, bgtu` - **JUMP**: `jal, jalr` - **SYSTEM**: `ecall, mret, ebreak, csrrw, csrrs, csrrc, csrrwi, csrrsi, csrrci` - **RV64I**: - **LOAD/STORE**: `lwu, ld, sd` - **OP-32**: `addw, subw, sllw, srlw, sraw, or, and` - **OP-IMM-32**: `addiw, sllw, srliw, sraiw` - **Pseudoinstructions** - **BASIC**: `nop` - **LOAD**: `la, li`, - **OP**: `mv, not, neg, negw, sext.b, sext.h, sext.w, zext.b, zext.h, zext.w, seqz, snez, sltz, slgz` - **BRANCH**: `beqz, bnez, blez, bgez, bltz, bgtz, bgt, ble, bgtu, bleu` - **JUMP**: `j, jal, jr, jalr, ret, call, tail` - **Extensions** - **RV32M/RV64M**: `mul, mulh, mulhsu, div, divu, rem, remu` - **RV64M**: `mulw, divw, divuw, remw, remuw` - **RV32A/RV64A**: `lr.w, sc.w, amoswap.w, amoadd.w, amoxor.w, amoand.w, amoor.w, amomin.w, amomax.w, amominu.w, amomaxu.w` - **RV64A**: `lr.d, sc.d, amoswap.d, amoadd.d, amoxor.d, amoand.d, amoor.d, amomin.d, amomax.d, amominu.d, amomaxu.d` - **Zicsr**: `csrrw, csrrs, csrrc, csrrwi, csrrsi, csrrci` For details about RISC-V, refer to the ISA specification: [https://riscv.org/technical/specifications/](https://riscv.org/technical/specifications/). ## Links to Resources and Similar Projects ### Resources and Publications - Computer architectures pages at Czech Technical University in Prague [https://comparch.edu.cvut.cz/](https://comparch.edu.cvut.cz/) - Dupak, J.; Pisa, P.; Stepanovsky, M.; Koci, K.

Resulting files are available in `Actions` /``, section `Artifacts`, file `target-wasm-Linux-qtx.xx.x`. Download the files and skip to deploy. Details on the build process can be found in `.github/workflows/cmake.yml`. ## Jump start 2 Install `emsdk` and `aqt` (details below). Use prepared helper make in the root of the project. ```shell make wasm # build make wasm-clean # clean wasm build make wasm-clean-deap # also clean cached external libraries - when changing compile settings, of when it just does not work ;) make wasm-install-qt # install appropriate qt for wasm using aqt ``` Behavior of this commands is customized to local system in `.dev-config.local.mk`. The file is provided as a template and further changes are ignored. ## Dependencies - WASM compiler (Emscripten/EMSDK) - WASM compiled Qt - bash compatible shell (not fish, unfortunately) Steps: - Install `emsdk` toolkit. Installing just the Emscripten compiler might work, but I would discourage it. - Choose version of the toolkit and run `emsdk activate `. You can choose freely as long as all your components are compiled with the compatible version. Qt5 distributed release is build with version `1.39.8`. Some distributions provide packages like `qt5-wasm`. It is imperative to compile the project with the same toolchain, otherwise it might not link. - Source the toolkit as suggested by the output of the activate command. - Download or compile qt to wasm. Common way is to store it in `/opt/`. I use an unofficial qt downloader [`aqtinstall`](https://pypi.org/project/aqtinstall/). - `python -m aqt install 5.12.2 linux desktop wasm_32 --outputdir "/opt/qt"` ## Build - Move to build directory a build directory (I use`build/wasm`) and run (replace the paths accordingly and use your favorite buildsystem): ```shell emcmake cmake ../.. -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=/opt/qt/5.13.1/wasm_32/ -DCMAKE_FIND_ROOT_PATH=/opt/qt/5.13.1/wasm_32/ -Wno-dev -G Ninja ``` - Move the resulting `.js` and `.wasm` files to `target/wasm` along with all content of `data/wasm`. It contains loader script, icons and other support files. ## Deploy - Move the contents of `target/wasm` to a webserver. Done. - Note: the webserver must use https due to CORS. ## Tricks ### Fish and co. If you wish to use bash incompatible shell. Run bash, source the file, and the run the shell with the environment of the bash. qtrvsim-0.9.8/docs/developer/build&deploy/media/000077500000000000000000000000001467752164200216315ustar00rootroot00000000000000qtrvsim-0.9.8/docs/developer/build&deploy/media/obs-ci-step-1.png000066400000000000000000001320211467752164200246210ustar00rootroot00000000000000‰PNG  IHDR6š{WT)€IDATx^ìÝXTÛ¡7|î“ä{“xfh3C•Þ{iÒ”n9vìÝcïÇ®ØP° *–£¢("½#¨1ùòÞ$÷~ÉÍM=77ÉIÎ9‰ßÚ³†Í0{€õïó{|ö^{Ížaí)ë?kí=Z"#cž®àÓBD͈4" hDÐ ˆ( AQ@ƒ ¢€AD ‚ˆ4" hDÐ ˆ( AQ@ƒ ¢€AD ‚ˆ#ÀÜÆÑÕ3À'`2PVv®#ÈÜÊA(±ä6ûÀ>°ƒÂm–·ñ17)·5ÞÒðsˆ(ðV"SÒi#l=,lœ ½@nC½ }¡DbnC:‚ºÆÜ­\ÞAA“Ž”oIÞÐsPˆ(ðVH§ÍÁÕ—Ûú˜©£H-I/[Îõá4éHQSKò†Ò˜ƒz#Š¡Ç"ßÕÅQg~óMÂ¥ßE®õµ™´ ·¦‚°ËÿH¹þFA╯"V¹OFë'w’©s§poÎlMa¶†ÇÒU¾Èßen^xÚ/®þ=éêW±§^M\’fnÕg´+&çÛ„3¹»úðh ÝŸ>+ˆ¸›4Šõñ?ÐC?ÖØ”»ud™Y[;¸9yø»ùLP²r/侸@}è¼n7è#§¾^ ÄÜfÐ5äAA“Žõµ$OµÆTÅûQôÌ]V6§äÿ‹ˆ=Úν‰:" ÷OÓ&ã¶ìÝδáPñ…Ó2MD~žÊÝ:âF'¢À MîbSk]C ·Â"û'÷Bî‹Ü#‚ Œš`Þ‹:¨¯¨O:ƒ}QýA4éHQ_KòTkLU¼—ÅaÝÏHÏ2îØ=KGûÞr=“±1gãóþ™œ÷7'G[¶<àü_³žÈßœD”伯¸»xïa¢EÞW1YõÍø3¹Ss…jÚFñ$Ÿ$d^¦«nG~OªùO¯£ïº<6çÛä«?340’íÜÜU`:™R÷OÓÁ;Ϥúö¶¿êøÂ)43ÄŸZÃÝ:âÄÓxÍ9Aˆ yKg{C#ŧº‘{$÷Kî» `Ä‘î·jíZÙ¹r å}M:RÔÚ’<S£Q¬Ü·ï;~ììå„™ äËf.$…d©À½•}׳¤›ñP `‚„ÿ$f$f•këÉJ¸ýøþ" á-%®L–MmdæzÍU¨#Šl"åaÓ&e¾¾]¹» w¹»2™÷%©èêÈÝ$/4ãs UÄýÓFŒžDGšÓ†Šo`³ÿôEKÃaÝvt#Ê ôÞv¢Iª<ŸÕ‡Ü;R Œ‚©ë6‚ÔÚ ´ øA4éHQkKòThLUŒjDÙ±ÿø¾´ŒE+>#d|°lØ,URH6‘”½•·ã"½X‡~¿§wüü7¤B€»£®å!Ú奢7ÄÒ D»“d# _ÂĬ2…:žéÿ“’ÿOs#¦Ñø R?1«‚3t,¹%ï³µ•Í·‰ºú ;ÑKàþ„ÜÊÉ&*`ÏO¤ã6_Çor ðâé™ÙϾ•ù‡¤¼L?Õé®üL¢¿?MÇ<Â{MYì…¯’rþs¼Ý'q¥®~Ÿ®¶qÐÖI{:ã²ÿ’|íq?

`CMakeLists.txt` - Update debian changelog - Make sure, CMake was configured with flag `-DDEV_MODE=true` to enable packaging tools. Without this flag, CMake will not try to do anything, that would require an external tool. - Run `make open_build_service_bundle`. - Deploy the contents of `/target/pkg` to Open Build Service (and Launchpad). ## Debian changelog Debian changelog has very strict (and little weird) format. Bash script `extras/packaging/add-to-changelog.sh ` generates a new entry in the changelog and opens it in `$EDITOR`. Edit CAREFULLY, the format is fragile. After that, changes are committed and git tag is updated. ### TODO - Decide, whether this should be replaced with CMake. - Get version from CMake ## `open_build_service_bundle` target At configure time, package related files are injected with up to date information from CMake (variables prefixed `PACKAGE_`) and copied to ``/`pkg`. This target bundles sources to `tar.xz` and updates hashes in the package files. ### Generate using GitHub Actions (CI) In the repository page at GitHub go to actions tab and choose release in the left menu. ![](./media/obs-ci-step-1.png) Click `run workflow` and select a branch. ![](./media/obs-ci-step-2.png) One the workflow has finished, the bundle is to be found in the artifacts section. Upload this bundle to OBS. ![](./media/obs-ci-step-3.png) ### TODO - Package signing ## Open Build Service The easiest way to deploy files to OBS is the `osc` cli tool. - Setup credentials. The first run of `osc` will lead you. - Download the repository: ```shell osc co home:jdupak qtrvsim ``` - Copy files to `home:jdupak`/`qtrvsim`. - Add files to tracking (in the `qtrvsim` directory): ```shell osc addremove * ``` - Commit changes and push: ```shell osc commit ``` - If something went wrong, delete th directory and start from th beginning.

It is fully sufficient to use it in browser, but installable version is available as well. ## Prepare your workspace Before you begin and open the diagram, you have to enable some plugins in menu `Extra`/`Plugins...`. Tou will need `tags`. Choose it and reload the app. You will need to enable the tools `Tabs` and `Hidden Tabs` in the `Extras` menu. I also recommend enabling `Layers` tool in view. ## Export You have to export 3 SVG files. In the `Tags` window, empty the field and click `Hide`. Everything will disappear. Then type `simple` and click show. It will show only components tagged as simple. No hit `File`/`Export as...`/`SVG...`. Uncheck the `include a copy of diagram` option and git export. Save as `simple.svg` to `device` and move it to project directory (`src/gui/core`). Hit hide and repeat for other versions ( currently `simple`,`pipeline` and `forwarding`). ## Editing You can load the diagram from device or from GitHub. Device is preferred as it will not create many useless commits. All shapes I have used are on [my GitHub](https://github.com/jdupak/Diagrams.net-CPU-scheme-kit). You can open it in `File` /`Open library from`. If you need write access just open an issue. The editor itself is quite intuitive, so here are only special functions and highlights: - When using texts, make sure, that formatted text option is disabled. It would use SVG foreign objects, which are not supported in most simple renderers and parsers. The option is cca in the middle of the text tab on the right. - If you need to ensure that some elements are inside others in the resulting SVG, you have to use `Custom element`, otherwise the SVG is flattened. Currently, it is how cache works. In the style tab, you can see inspect it by the ` edit shape` button. Make sure to select the element and not some group. You can create new one in `Arrange`/`Insert`/`Shape...`. The language is similar to SVG but not the same, and it is documented here: [https://www.diagrams.net/doc/faq/shape-complex-create-edit](https://www. diagrams.net/doc/faq/shape-complex-create-edit) with complete language reference here: [https://jgraph.github. io/mxgraph/docs/stencils.xsd](https://jgraph.github.io/mxgraph/docs/stencils.xsd). This is the code of the cache: ```xml ``` - Components with dynamic values are created in `Edit data` in context menu (`CTRL+M`). Example (written here as a json): ```json { "component": "instruction-value", "source": "decode" } ``` Components are handled in `src/gui/coreview/scene.cpp`, defined in `src/gui/coreview/domponents` and data bindings (source attribute) are controlled in `src/gui/coreview/data.h`. ![](./media/data.png). - In context menu - `Edit link...` you can create hyperlinks, what will open some part of gui on doubleclick.

To enable logging in a `cpp` file, add the following snippet. ```c++ #include "common/logging.h" LOG_CATEGORY("."); ``` This creates a category object in the scope and enables seamless use of logging macros `DEBUG` `LOG` `WARN` and `INFO`. If you need to use logging in a header file, call the `LOG_CATEGORY` macro only in a local scope to avoid interfering with log categories in source files. Debug logs are intended to provide fine level of information and should be hidden by default and enabled only for currently debugged category. Debug logs are removed from all `release` builds. ## Using the log Qt supports both C++ streams and `printf`-like interface. **In this project, only `printf` style logs should be used.** Logs are considered to be part of the documentation and stream are too hard to read. The only exception is compatibility with used libraries (curretly *svgscene*). To print any Qt type, just wrap it with `qPrintable` macro. **Example:** ``` QT_LOGGING_CONF=/data/Dev/school/QtRvSim/qtlogging.ini; ``` ```cpp DEBUG("Link triggered (href: %s).", qPrintable(getTargetName())); ``` ## Configuring the log To filter shown logs, modify `qtlogging.ini` file in the root of the project. If this config is not found automatically, use `QT_LOGGING_CONF`environment variable. **Example:** ```shell QT_LOGGING_CONF=/data/Dev/school/QtRvSim/qtlogging.ini ``` **Configuration example** (shows debug logs from `instruction.cpp` only): ```ini [Rules] *.debug=false machine.Instruction.debug=true ```qtrvsim-0.9.8/docs/developer/debuging/sanitizers.md000066400000000000000000000014171467752164200224740ustar00rootroot00000000000000# Runtime sanitizers ## Using sanitizers in this project All debug builds are by default built with address and undefined runtime sanitizers. To disable them (which is strongly discouraged) run cmake with options none. ```shell cmake -DSANITIZERS=none ``` To run other selection of sanitiser use, pass colon separated list to the command. ```shell cmake -DSANITIZERS=memory,undefined ``` NOTE: Some sanitizer cannot be used together, like address and memory. ### Sanitizer debug info and Clang If you are using sanitizers with clang and you don't files and line numbers, make sure that `llvm-symbolizer` is installed and if that does not help, add env `ASAN_SYMBOLIZER_PATH=` with path to your symbolizer executable. Most of the time, having it in `PATH` should be enough. qtrvsim-0.9.8/docs/developer/need-to-know.md000066400000000000000000000027271467752164200210310ustar00rootroot00000000000000# Need To Know **Critical information for every developer.** ## Modal Windows, Dialogues, Message Boxes In typical, native, Qt setting, modal windows allocated on stack and block upon opening. To manage the modal window, Qt spins up a second event loop. However, that is not technically possible in Web-Assembly environment. *(This might be solved in new Qt with “asyncify†build flag, but it does not work with currently used Qt 5.15.2)* [Read more](http://qtandeverything.blogspot.com/2019/05/exec-on-qt-webassembly.html) ### Broken API usage ```cpp QMessageBox msg; msg.exec(); ``` ```cpp QMessageBox::critical("Hello"); ``` The `.exec()` method and single line call are typical warning signs. Some parts of code employ special code for Web-Assembly (like HTML file selector) and the native part may use blocking solution. However, in performance non-critical parts (which most dialogs are), unified asynchronous solution is preferred. ### Solution The modal window object has to be allocated dynamically and started using asynchronous method `open`. Answer has to be obtained via `connect` callback. For ease of use, wrapper functions are prepared in `gui/helper/async_modal.h`. Free can be accomplished using special call `msg->setAttribute(Qt::WA_DeleteOnClose)` before opening. This method is automatically employed in `async_modal.h`.

See developer docs. ## GUI ### Portable application *The simulator GUI stores information about currently opened windows, last selected micro-architecture, etc. To make the simulator fully portable, you have to specify path to a `.ini` file to store this state.* `QTRVSIM_CONFIG_FILE` - path to `.ini` file with current GUI state.qtrvsim-0.9.8/docs/user/exec-formats-and-tools.md000066400000000000000000000241371467752164200220050ustar00rootroot00000000000000QtMips - Supported Executable Formats and Toolchains ==================================================== The simulator accepts ELF statically linked executables compiled for 32-bit big-endian MISP target. Optimal is selection of some basic/initial mips architecture and the use of plain mips-elf GCC toolchain. Then the next simple template can be used to compile assembly source codes. ``` #define zero $0 #define at $1 #define v0 $2 #define v1 $3 #define a0 $4 #define a1 $5 #define a2 $6 #define a3 $7 #define t0 $8 #define t1 $9 #define t2 $10 #define t3 $11 #define t4 $12 #define t5 $13 #define t6 $14 #define t7 $15 #define t8 $24 #define t9 $25 #define k0 $26 #define k1 $27 #define s0 $16 #define s1 $17 #define s2 $18 #define s3 $19 #define s4 $20 #define s5 $21 #define s6 $22 #define s7 $23 #define gp $28 #define sp $29 #define fp $30 #define ra $31 .globl _start .set noat .set noreorder .ent _start _start: // write the code there loop: break beq zero, zero, loop nop .end _start ``` The simulator recognizes 'break' instruction compiled into the program. When 'break' instruction is fetched, exception propagates through the pipeline. The simulator waits till the pipeline is empty and stops the continuous execution. PC is set to the next instruction in the program flow. When a single step or continuous execution is activated again then the program continues after the 'break' instruction. Another option is to set up "hardware" breakpoint for a given instruction address. When the instruction from address marked by breakpoint is fetched then the exception propagates through the pipeline, all externally visible effects of instruction marked by breakpoint are masked out in memory phase, all following instructions in the pipeline are discarded and execution stops. PC is set to the address of instruction causing the exception or to the branch instruction address if the exception occurs in delay slot. When the single step or continuous execution is requested again then the "hardware" breakpoint exception in the fetch stage is masked for the first executed instruction. But then CPU accepts breakpoint exceptions again. This is why it is not a good idea to set up breakpoint to address of an instruction in the delay slot. To compile simple assembly code programs invoke GCC with next options. ``` mips-elf-gcc -ggdb -c program.S -o program.o mips-elf-gcc -ggdb -nostdlib -nodefaultlibs -nostartfiles program.o -o program ``` Compile Executables with 'mips-linux-gnu' Toolchain --------------------------------------------------- The Linux targetting toolchains use a MIPS O32 ABI calling convention which allows building position-independent binaries (PIC, PIE) and overcome missing PC relative support in the basic MIPS instruction set. The ABI uses strictly convention equivalent to calling each function indirectly through 't9' register ('jalr t9'). The known value pointing to a start of called function allows computing Global Offset Table (GOT) and global data pointers values from known offset and 't9' register value. The startup code which conforms these requirements to call 'main()' function looks like this: ``` /* file crt0local.S - replacement of C library complete startup machinery */ .globl main .globl __start .set noat .set noreorder .ent __start .text __start: bal next nop next: .set noreorder .cpload $31 .set reorder addi $a0, $zero, 0 addi $a1, $zero, 0 jal main quit: addi $a0, $zero, 0 addi $v0, $zero, 4001 /* SYS_exit */ syscall loop: break beq $zero, $zero, loop nop .end __start ``` The sequence of relative jump and link to next instruction setups return address register 'ra' to the value of the next instruction after 'bal', and the delay slot. Actual translated code replaces pseudo-instruction '.cpload' by sequence adding offset into global data area from actual instruction address and stores result in the 'gp' ``` 00400500 <__start>: 400500: 04110001 bal 400508 400504: 00000000 nop 00400508 : .cpload $31 400508: 3c1c000a lui gp,0xa 40050c: 279c6238 addiu gp,gp,25144 400510: 039fe021 addu gp,gp,ra 400514: 20040000 addi a0,zero,0 400518: 20050000 addi a1,zero,0 40051c: 8f998018 lw t9,-32744(gp) 400520: 0411ffc6 bal 40043c
400524: 00000000 nop 00400528 : 400528: 20040000 addi a0,zero,0 40052c: 20020fa1 addi v0,zero,4001 400530: 0000000c syscall 00400534 : 400534: 0000000d break 400538: 1000fffe b 400534 40053c: 00000000 nop ``` It can be seen that assembler does not only expand '.cpload' but even marks 'jalr t9' instruction as a target for link time optimization. Because 'main' function is near (offset less than 128 kB) to the startup code, the 'jal' instruction is replaced by 'bal main' during linking phase. Then simple main function which outputs string to the serial port provided by QtMisp emulator can be implemented as: ``` /* serial-port-test.c */ #include #define SERIAL_PORT_BASE 0xffffc000 #define SERP_ST_REG_o 0x00 #define SERP_ST_REG_TX_BUSY_m 0x1 #define SERP_TX_REG_o 0x04 static inline void serp_write_reg(uint32_t base, uint32_t reg, uint32_t val) { *(volatile uint32_t *)(base + reg) = val; } static inline uint32_t serp_read_reg(uint32_t base, uint32_t reg) { return *(volatile uint32_t *)(base + reg); } void serp_tx_byte(int data) { while (serp_read_reg(SERIAL_PORT_BASE, SERP_ST_REG_o) & SERP_ST_REG_TX_BUSY_m); serp_write_reg(SERIAL_PORT_BASE, SERP_TX_REG_o, data); } int main(void) { const char *text = "Hello world.\nI am alive.\n"; const char *s; for (s = text; *s; s++) serp_tx_byte(*s); return 0; } ``` Compilation: ``` mips-linux-gnu-gcc -ggdb -fno-lto -c crt0local.S -o crt0local.o mips-linux-gnu-gcc -ggdb -O3 -fno-lto -c serial-port-test.c -o serial-port-test.o mips-linux-gnu-gcc -ggdb -nostartfiles -static -fno-lto crt0local.o serial-port-test.o -o serial-port-test ``` Simulator Compatability with Musl libc -------------------------------------- The 'mips-linux-gnu' toolchain can be alternativelly used with [musl libc](http://www.musl-libc.org/). The library can be built for the MIPS target by command ``` ../musl/configure CC=mips-linux-gnu-gcc LD=mips-linux-gnu-ld --target=mips-linux-gnu \ --prefix=/opt/musl/mips-linux-gnu --enable-debug --enable-optimize ``` User projects can be compiled and linked against 'musl libc' by specifying '-specs' option during C compiler invocation. ``` mips-linux-gnu-gcc -ggdb -O1 -march=mips2 -static -specs=/opt/musl/mips-linux-gnu/lib/musl-gcc.specs -c program.c -o program.o mips-linux-gnu-gcc -ggdb -march=mips2 -static -specs=/opt/musl/mips-linux-gnu/lib/musl-gcc.specs program.o -o program ``` The simulator implements 'rdhwr $rd, userlocal' instruction and allows code compiled agains [musl C library](http://www.musl-libc.org/). to start with libc provided 'crt0.o'. But there are multiple syscalls in the startup code which cause stop of continuous run mode and require to press run button again. It is better to use simple C library startup code replacement. It is enough to run 'printf()', 'sprintf()' and 'sscanf()' functions without complete C library initialization. Next variant supports both PIC/PIE and non-PIC environment. ``` /* minimal replacement of crt0.o which is else provided by C library */ /* this variant support both static and PIC/PIE environments */ .globl main .globl _start .globl __start .set noat .set noreorder .ent _start .text __start: _start: #if defined(__PIC__) || defined(__pic__) bal next nop next: .set noreorder .cpload $31 .set reorder #else la $gp, _gp #endif addi $a0, $zero, 0 addi $a1, $zero, 0 jal main nop quit: addi $a0, $zero, 0 addi $v0, $zero, 4001 /* SYS_exit */ syscall loop: break beq $zero, $zero, loop nop .end _start ``` Using of Make Utility with QtSim -------------------------------------- The invocation of the compiler and 'gcc' in the role of the linker can be automated. The 'make' utility is the standard solution. Next 'Makefile' provides a template for automation of these tasks ``` ARCH=mips-elf #ARCH=mips-linux-gnu SOURCES = crt0local.S qtmips_binrep.c TARGET_EXE = qtmips_binrep CC=$(ARCH)-gcc CXX=$(ARCH)-g++ AS=$(ARCH)-as LD=$(ARCH)-ld OBJCOPY=$(ARCH)-objcopy #ARCHFLAGS += -march=mips3 ARCHFLAGS += -fno-lto #ARCHFLAGS += -mno-shared CFLAGS += -ggdb -O3 -Wall CXXFLAGS+= -ggdb -O3 -Wall AFLAGS += -ggdb LDFLAGS += -ggdb LDFLAGS += -nostartfiles LDFLAGS += -static #LDFLAGS += -specs=/opt/musl/mips-linux-gnu/lib/musl-gcc.specs CFLAGS += $(ARCHFLAGS) CXXFLAGS+= $(ARCHFLAGS) AFLAGS += $(ARCHFLAGS) LDFLAGS += $(ARCHFLAGS) OBJECTS += $(filter %.o,$(SOURCES:%.S=%.o)) OBJECTS += $(filter %.o,$(SOURCES:%.c=%.o)) OBJECTS += $(filter %.o,$(SOURCES:%.cpp=%.o)) all : default .PHONY : default clean dep all %.o:%.S $(CC) -D__ASSEMBLY__ $(AFLAGS) -c $< -o $@ %.o:%.c $(CC) $(CFLAGS) $(CPPFLAGS) -c $< -o $@ %.o:%.cpp $(CXX) $(CXXFLAGS) $(CPPFLAGS) -c $< %.s:%.c $(CC) $(CFLAGS) $(CPPFLAGS) -S $< -o $@ default : $(TARGET_EXE) $(TARGET_EXE) : $(OBJECTS) $(CC) $(LDFLAGS) $^ -o $@ dep: depend depend: $(SOURCES) $(glob *.h) echo '# autogenerated dependencies' > depend ifneq ($(filter %.S,$(SOURCES)),) $(CC) -D__ASSEMBLY__ $(AFLAGS) -w -E -M $(filter %.S,$(SOURCES)) \ >> depend endif ifneq ($(filter %.c,$(SOURCES)),) $(CC) $(CFLAGS) $(CPPFLAGS) -w -E -M $(filter %.c,$(SOURCES)) \ >> depend endif ifneq ($(filter %.cpp,$(SOURCES)),) $(CXX) $(CXXFLAGS) $(CPPFLAGS) -w -E -M $(filter %.cpp,$(SOURCES)) \ >> depend endif clean: rm -f *.o *.a $(OBJECTS) $(TARGET_EXE) depend #mips-elf-objdump --source -M no-aliases,reg-names=numeric qtmips_binrep -include depend ``` The example provides defines which allow select compiler to be used ('mips-elf' or 'mips-linux-gnu') and enable build agains musl libc. qtrvsim-0.9.8/external/000077500000000000000000000000001467752164200150755ustar00rootroot00000000000000qtrvsim-0.9.8/external/compiler/000077500000000000000000000000001467752164200167075ustar00rootroot00000000000000qtrvsim-0.9.8/external/compiler/compile.sh000077500000000000000000000013231467752164200206750ustar00rootroot00000000000000#!/usr/bin/env bash #

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. {one line to give the program's name and a brief idea of what it does.} Copyright (C) {year} {name of author} This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: {project} Copyright (C) {year} {fullname} This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library.
