Various operating systems

Perhaps most people know about windows, and maybe quite a few people know about Linux and even know about the conflicts between Linux and Windows. However, I am afraid I know very little about the operating system produced in China. Can mention the name, I am afraid that there is only the red flag of CAS, national Defense Technology University of the Milky Way kylin. But are there only so many operating systems for commercial or scientific research that people make in their operating systems?

The truth is far from it. In the private sector, there are already a large number of operating system personnel in the savings of their own power, has been outstanding work published out, which contains both magic Linux, Relaxbsd This analogy of the mature system, but also the beginning of only a simple command line of the experimental operating system. Their efforts should not be buried,

In order to let you know that there are so many different operating system projects going on in our country, I intend to build a list of domestic operating system projects and maintain this list all the time. I know there are a lot of domestic operating system very persistent people, some people have established their own operating system projects, but because there is no way to attract attention, long time, also slowly lost interest. The efforts made by these people for China's operating system are worthy of admiration. So I would like to go through this list so that all the operating systems may be able to find a partner through this list, and I hope that this list will allow some of the newly started operating system projects to be concerned. I would like to support our country's operating system business.

I can't collect all the items, so I hope you can help me with the collection of these items. Whether it is the official, or the private, whether it is open source, or closed source, whether the past lively, now no movement, or so far still hot, whether it is completely original, or on the basis of other people to transform. I will collect this list only if the people in the country are trying to do it and can still find it online today.

And, assuming it is possible, I would also like to collect these works and mirror them on my site. Well, don't say more, just want you to know, and do not exist in my list, write me an email or a message. I will confirm that after adding to the list. It is best to tell me the name of the operating system project, author (person or organization), site link or email. Dancefire#gmail.

Well, assuming there's an organization that studies the operating system, you can tell me that I'm also going to put these domestic research operating systems in here.

Simple Introduction

Anos

http://larryli.51.net/anos/
Anos is an operating system (an Operating system). A i386 operating system as simple as possible, or just a system. Programs that do not require other things to be executed on the computer.

Anos itself is not meant to exist as a useful OS, but to be present as an OS demonstration. As simple as possible to show the detailed code of an operating system is the purpose of anos. Although Minix also has the same Linux 0.01/0.11 for us to provide this demo. But Minix is based on micro-kernels and has done a lot of extra work (which is necessary for a useful system), and its code is quite large. As for the Linux initial version number, of course is a good example of a small system, but its code is a bit confusing (very strong hacker style). And the other small OS is not complete is to have such a disadvantage.
One of the drawbacks is that we are mostly using WIN32 systems, which are rarely developed under the Win32 platform. The OS is not known by reading the code, so it is not a practical opportunity to study the OS. Often everyone but build a platform for research is annoying to quit.
Therefore, Anos chooses Win32 under the MinGW GNU C compiler and NASM assembler as well as the QEMU emulator for development. At the same time, Anos will publish an OS at different stages of the source package, showing the state of the OS development in accordance with the progress. And, as much as possible, provide enough documentation and code gaze. Make it easy for everyone to participate in the Anos code to understand the OS.

Composition of the deltaos®

Deltaos consists of kernel deltacore, file system Deltafile, and network protocol deltanet.

Kernel-deltacore

Deltacore enables applications to be executed in multi-tasking, communication and synchronization between tasks, and Deltacore provides mechanisms that enable applications to intercept and respond to external events in a timely manner.

In terms of application programming interfaces, Deltacore also supports two other APIs, in addition to its own API, which are:

POSIX API
VxWorks API.
Network-deltanet

Deltanet is a network protocol that enables electronic devices to communicate with other devices in the form of a TCP/IP protocol, which also enables an electronic device to become a global network-an Internet

File-deltafile

Deltafile enables applications to manage large storage spaces in electronic devices as files, which may be internal memory RAM, external memory hard disks or floppy disks, or new storage devices-flash memory.

The development course of Deltaos

After the development of industrialization, we developed a complete product line which can adapt to the development of embedded application. Product series named "Tao System" Deltasystem, and won the national 863 major software special support. Mainly includes embedded real-time operating system Deltaos, embedded integrated development tools Lambdatool, embedded application components and test tools Gammaray.

Dooloo RTOS

http://blog.chinaunix.net/article.php?articleId=59068&blogId=11037 [Simple Introduction link]
The Dooloo RTOs is a real-time operating system composed of 3 chunks of ukernel (real-time kernel), BSP (Board support packages, board-level supporting package), Kernel Services (core service layer).

The real-time kernel Ukernel is written in the 100% standard C language and contains:
-Task scheduling: Support multi-task scheduling, using a priority-based preemption task scheduling algorithm, support 256 priority (0-255,255 by the spare task, not generally used), the same priority of the task use time-slice-based rotation scheduling strategy.
-Task synchronization mechanism: Semaphore and priority-based inheritance of mutually exclusive locks, can effectively prevent the task of priority rollover.
-Inter-mission communication mechanism: has rich communication mechanism between tasks, message queue, mailbox and asynchronous signal. Each communication mechanism is equipped with the acquisition of waiting time, guaranteeing real-time.
-Interrupt Handling: Interrupt handling supports nested mode of interrupt handling.
-Memory management: supports static memory management and heap real-world dynamic memory management.
-Device Management: Implements the device management subsystem by name, which covers the driver interfaces of character devices, block devices, MTD devices and network card devices.

The BSP board-level support package includes parts related to the underlying hardware, written by the Assembly and standard C, and when ported to a new platform, it is only necessary to implement or transplant the underlying BSP once again. From the current workload, porting to a completely new platform takes about one months. Now BSP supports:
-x86 protection mode
-Arm7tdmi (s3c4510,s3c44b0, ep7312, etc.)

Kernel Service (Core service layer) is mainly provided by the corresponding application of the upper level of the kernel services, including nearly hundreds of standard C, POSIX interface functions.

[Project may have terminated, development power transferred to next generation microkernel embedded RTOs Rt-thread]

Edenos

http://edenos.diy.myrice.com/
The Edenos is a fully 32-bit PC operating system that requires more than 386 machines. It has a short core and a very fast start-up, even if it takes about 1 seconds to boot from the floppy disk. After the boot execution in the protection mode, now has finished the 32-bit display, the keyboard, the floppy drive, the hard drive and so on, can use the command to display 32-bit linear memory, conduct I/O test, read and write Watch the hard drive structure, etc. now that you have a multi-tasking test, you are developing a memory management module.

Eden uses VC7.1 as the main compilation tool (once with VC6.0), compiles a small number of 16-bit/32-bit assembly code with Tasm5.0, and uses its own linker to blink links to generate running code. So it's easy to develop programs for Eden, just to be able to use VCs.

Elastos and Hin operating system

http://www.elastos.com.cn/
"and Hin" operating system is developed by the Tyco century with completely independent intellectual property rights of the 32-bit embedded operating system.

About 2003 National Day holiday, I wrote my first "operating system" with the Micro OS Emu8086 this software, and the boot program read the "kernel" of the specified sector into memory and then gave it to the kernel to execute, and I was happy.

Unlike most operating system projects, my "Write your own operating system" tour starts completely from scratch, taking a long time from the bootloader to the kernel implementation, and my base is pretty poor, so the first version number is just a simple sector read, As well as displaying some characters, and then providing input service via BIOS 16th interrupt-This is a 16-bit system model; On this basis, I wrote 0.0.2 and 0.0.3, which are 16-bit system models that appear to be just more like a real-mode operating system Because of the desire to have an operating system, it took quite a long time to delve into protection mode and after several experiments and other code references, Exos finally worked in protected mode.

Learnos

http://writeos.com/
This is a boot program that simulates DOS, but it's just a boot program, with a 512-byte exception.

In this bootloader, we initially implemented the DOS interface, simulated implementation, and implemented DOS two commands--cls and reboot.

This is a rudimentary implementation, and the real implementation cannot be done entirely in the bootloader. The bootloader's function should be bootstrap. But we're just a demo here, at least I'm excited to see my own simulated DOS environment. This is the biggest motivation for you to learn about system development.

It has not yet implemented the BACKSPACE key feature. Uppercase and lowercase are not yet implemented, and the various function keys are not processed. But that doesn't affect what he's doing now as a demo code.

What we're going to do next is Fat12 format compatibility, although we can specify our own format as written in the tutorial. But that would only make my little system more isolated.

Lingix Operating System

http://lingix.gro.clinux.org/
Works initiated by Huazhong Normal University Chenbin

Linux compatible kernel

http://linux.insigma.com.cn/
This is not a simple Linux kernel Oh, this is the new Maudeca of Zhejiang Big Net initiated a Windows and Linux compatibility attempt at the kernel level. Attempts to support Linux and Windows programs at the same time in the kernel. They introduce themselves in this way:

Our goal is to expand the Linux kernel into a compatible kernel that supports both Linux and Windows applications, Linux device drivers, and Windows device drivers, enabling users to efficiently execute Windows applications directly on Linux. Without the use of the Windows operating system.
We want to develop such a compatible kernel, is to improve the market competitiveness of desktop Linux, for the majority of users to provide a choice, so that many other people can afford to use the computer, but not the intention of Microsoft to challenge, and no matter what emotional factors.

Our project is an open source project which is invested and hosted by Zhejiang Big Network New Technology Co., Ltd., we will abide by the GPL rules and open the source code which should be disclosed according to regulations. We welcome the wide range of netizens and enthusiasts around the world to form a Linux-compatible kernel of the open source community. Such participation can be embodied in code, programs, information and other aspects of the contribution, but also can be reflected in the encouragement for the companion, for the project and Shout.

Magic is used to solve these problems. It is recommended to install Magic to try to be clear.

MenuetOS

http://www.xemean.net/menuet/
MenuetOS is an amateur operating system developed for x86 (IBM compliant) computers, a mini operating system written entirely in assembly language (32-bit), so it is smaller, faster, and the system itself consumes very little system resources with applications.

The project was originally developed by Finnish Ville Turjanmaa (University of Helsinki) in spare time. Today there are menuetos developers around the world who are constantly working on this operating system.

The project is now being made by Jarek Pelczar (jarekp3[@]wp[). PL) Take over. The Chinese version of the project was developed by Webmaster E-mean X.

MenuetOS is not a Unix-like operating system as popular today as Linux and other like FreeBSD and Minix, and it is completely written by 32-bit Assembly languages. Menuet and its applications do not operate on the basis of any current operating system, primarily to avoid complex programming and unpredictable bugs during the development process.

Although Menuet is entirely written in a 32-bit assembly, its system program architecture is not entirely reserved for assembly language, and its interfaces are actually used in whatever programming languages. However, the purpose of the system development is to simplify the design of ASM, which is especially reflected in GUI programming.

Qiming OS

http://qimingos.51.net/
The author introduces it in this way:

"This is my dream in high school to start planning!" At that time I was not too understanding of operating system technology, or even do not understand! At that time my idea was this: to develop a small multi-tasking graphical interface of the Chinese operating system! Fully compatible with Linux, partially compatible with Windows.

Now it seems to be just a fantasy! Because it is not the only one who will dream of me. With my understanding of the operating system, my ideas are becoming more and more practical, and my thoughts now are:

First of all, this is not a useful operating system, although I have been working on this!

Second, the operating system will not be in the compatibility of the efforts! Since the development of this operating system itself is very difficult! Just, suppose I could still work on this!

Also, this is the operating system is open source! You are free to use the code inside (just note the source and write it in the Declaration section!). Oh! After all, this is my effort! I believe you will understand! ）”

The author introduces it in this way:

"This is one of my ideals, I want to turn it into reality."

First, it is made into a real-mode operating system, on this basis is to be familiar with the memory, hard disk operation and research on the composition of PC hardware.
After accumulating certain knowledge, we will conduct research in 32-bit protection mode, and further understand the processor mechanism and memory management mechanism under the protection mode.

The development environment is intended to be DOS-based

Not ready to make a graphical interface, because my aesthetics is very poor, once the program GUI did not dare to compliment.

In real mode is not ready to do network protocol, due to the hard programming of the network card does not understand. There is no information.
The file system is ready to use the FAT format, because this format is most versatile.

Power management via ACPI, which can be adapted to some of the features of notebooks

Some work has now been done on booting and restarting the computer.

Plan to complete the module completed design about 2 years and 4 months, just as I graduated from college
9 months of the development of real mode, the rest of the time for the development of protection mode

This project is open source project, all code all open "

"I do not know how to describe this site and I participated in the project, the station from the beginning of 2004 (the end of the lunar calendar 2003) So far, has been a year of the scene; The original purpose of the site construction is to establish a relatively comprehensive operating system development information, the development of enthusiasts to exchange platform, Because I found that the domestic operating system development is not very active, and to find a more centralized site is also very difficult to find the majority of some of the personal page is more dense site, my site I hope you crossing and like-minded people can be comfortable.
Over the past year, the site has been a lot of friends, I thank you, of course, the shortcomings of this site also invites you to enlighten. The site of the re-revision of the weight of the assembly and other high-level language, than the previous version number has a lot of other development resources; During the site execution, a lot of friends to me e-mail, give me many comments and suggestions, at the same time some friends have their own information and translation files on the station, greatly enriched the site; Site update is very slow, please forgive me.
Through the site I probably understand the situation of domestic operating system development, is optimistic, the site registered projects have been added, these projects are not lack of excellent work; but there are some projects that do not exist or have ceased to develop, of course, one thing is constrained by a lot of factors, which I hope you can understand. To a small station to visit a friend is expected to be very much is directed at MenuetOS, or from MenuetOS learned this site, very interesting point is: very many friends like my web design style and layout, and not many developers, sometimes I also think I do site rather than knock code.
Developing operating systems may be for the sake of immortality, or just personal interest, for learning the fundamentals of computer development and operating systems, not very difficult, of course, is not easy, you insist.
March 31, 2005 the second edition of this site is complete.
I would like to dedicate this to all the operating system development enthusiasts. ”
