HelenOS

Recently I have been delighted to watch the growing interest in our project. Not only are there more and more people on the project's mailing list and not only I receive increasing amount of questions about HelenOS from colleagues, friends and other ... [More] people, but there are currently four HelenOS-related master theses in progress at Faculty of Physics and Mathematics, Charles University. read more [Less]

After two very successful kernel camps in 2005 and 2006, a couple of HelenOS developers will gather again in order to work together for several days. The HelenOS Camp 2007 will take place between September 27 and September 30 in Beroun, Czech ... [More] Republic. There are several topics on the agenda already: design and implementation work on the block device layer and interface design and implementation work on the filesystem and VFS layer and interface extending and improving the ia64 port usual non-specific bug fixing and development in various areas In case of interest from our community members from abroad (and the Czech Republic as well), we can arrange for a skype (or similar) session covering the camp outcomes and different project-related topics.

[More] were several topics on the agenda, such as work on the virtual file system server (VFS) and the FAT file system implementation, device mapper task, improvements of the IPC so that data can pass multiple tasks without being shared or copied by the middle-men tasks, and also getting the ia64 port to run natively. More on the accomplishments of the camp can be found here and here. [Less]

HelenOS 0.2.0.5 has just been released. The release fixes several hard hangs and de-oversynchronizes certain areas of the kernel. This release also adds the new arm32 port as well as a simplified task termination. Smaller fixes here and there and greatly improved IPC in-source documentation. Go to the download page.

Current status of the arm32 port has been presented (in czech) by Petr Stepan.

The HelenOS project is an effort to develop a complete operating system. HelenOS uses its own microkernel written from scratch and supports SMP, multitasking and multithreading on both 32-bit and 64-bit, little-endian and big-endian processor ... [More] architectures, among wich are AMD64/EM64T (x86-64), IA-32, IA-64 (Itanium), 32-bit MIPS, 32-bit PowerPC, SPARC V9 and Xen 3.0. As of now, HelenOS is being developed mostly by faculty and students of Faculty of Mathematics and Physics at Charles University in Prague, but the project is open for everyone. The source code is available under the BSD license. Third party components are licensed under GPL or are public domain. In case you are interested in our project or have any questions about it, feel free to subscribe to our mailing list. The HelenOS operating system is, as of today, feature incomplete and the project is currently under heavy development. We are looking for people to join our team or to merely try out our system and become our beta testers. Here are the things that you could help us with. read more [Less]

The HelenOS project is an effort to develop a complete and usable modern operating system, yet offering room for experimenting and research. HelenOS uses its own microkernel written from scratch and supports SMP, multitasking and multithreading on ... [More] both 32-bit and 64-bit, little-endian and big-endian processor architectures, among which are AMD64/EM64T (x86-64), ARM, IA-32, IA-64 (Itanium), 32-bit MIPS, 32-bit PowerPC, SPARC V9 and Xen 3.0. Thanks to the relatively high number of supported architectures and suitable design, HelenOS is extremely-well portable. As of now, HelenOS is being developed mostly by faculty and students of Faculty of Mathematics and Physics at Charles University in Prague, but the project is open for everyone. The source code is open and available under the BSD license. Some third party components, and components based on GPL software, are licensed under GPL. There is also a minority of public domain code. In case you are interested in our project or have any questions about it, feel free to subscribe to our mailing list. The HelenOS operating system is, as of today, feature incomplete and the project is currently under heavy development (see roadmap). We are looking for people to join our team as co-developers or to merely try out our system and become our beta testers. Here are the things that you could help us with. read more [Less]

Today, Jakub Jermar completed his master thesis about porting the SPARTAN kernel to the SPARC V9 architecture. Download the text of the thesis here. During work on his thesis, Jakub brought support for sparc64 into HelenOS.
