Linux Unified Kernel 0.2.2-1 was released
On December 17 2008, the Linux Unified Kernel project released the version 0.2.2-1 of LUK.
The previous release (0.2.2) of the Linux Unified Kernel fixed a large amount of bugs in the implemented mechanisms, but there are still many key problems left, such as process running with ungrouped threads. Therefore, this version (0.2.2-1) has resolved some key problems.
What's new in this release:
- Fixed bugs in process/thread management
- Fixed bugs in virtual memory management
- Fixed bugs in synchronization
- Fixed bugs in Window management in Wine built-in dlls
Linux Unified Kernel (LUK) is a computer operating system kernel intended to be binary-compatible with application software and device drivers made for Microsoft Windows and Linux.
The LUK project aims to add all Windows kernel mechanisms into the Linux kernel, including process management, thread management, Object management, virtual memory management, synchronization, system calls (syscall), the application registry, WDM device driver framework, Windows DPC mechanism, etc., to form a new kernel. Thus, the new kernel allows both Linux and Windows applications and device drivers to work directly without virtualization or emulation.
But LUK is not simply an accumulation of the two kernels. In order to prevent LUK from becoming bloated, if a function has been completed in the ReactOS kernel, and it can also be achieved using the Linux kernel (ReactOS/Wine/NDISwrapper code as a reference if they have implemented the function), then LUK prefers to use the latter.
LUK has two sets of syscalls and their corresponding syscall tables: a Windows syscall set and a Linux syscall set. Windows applications call the syscall table via software interrupt "int 0x2e" to make a system call. Linux applications call syscall table via "int 0x80".
The LUK project does not develop the Windows and the Linux userland libraries. Those libraries are offered by the Wine (or Windows/ReactOS) project and the Linux project.
LUK is primarily written in the C programming language, and is licensed under the terms of the GNU General Public License. Although the project is in the alpha development stage as of 2008, many Windows programs already work well.
