Yeah, There is so many people like Dawid who is very interested in the Codezero L4 kernel written by C and also open sourced, Like me.In term of the technology of L4 it will be popular on the embedded system, especially in mobile telephone with the popularity of Android. Bandbase need RTOS and application need Linux, and how to merge these two systems need virtualize technology, this is what Codezero realized. So if Codezero is open to every fans of it, it will be going more strong.

I would like to announce that we have succesfully virtualized the Linux kernel over multicore Cortex-A9 processors. The implementation involves certain novel approaches where linux applications can switch between kernel and user address spaces with a neat trick I named as HyperSwitch. Unfortunately I haven't been able to release this directly to the open. I would like to have open source development go hand in hand with a business model that can self-fund the project. One way to create a self sustaining model like that is the dual licensed model or open core licensing. However, my concern is that creating anything self-sustaining is a challenge on its own, let alone a model where there is open and non-open options. In conclusion I am not dismissing the open development option, in fact that would be what I would enjoy the most. However I need to explore more on how to establish a solid way to take the project forward to be able to provide also an open option. One challenge is that when you open up, there is very few people who would appreciate and make a meaningful understanding or contribution to the project. In that respect I am considering to do this in a somewhat organized way where we would promote the use of Codezero and when we reach a threshold number of requests such as yours (i.e. people start caring more about this), then I would release it as open source. If you have other ideas I would be interested to know. Going forward, we will add support for Beagleboard, the Pandaboard (OMAP4 dual core cortex-A9) and possibly Nvidia Tegra2 SoCs. We have also plans to add support for Ubuntu netbook and Android distributions. We should be done by all by end of Q1 2011.
