Virtual address kernel modification for UNIX. [Use of modules with PDP-11]
Technical Report
·
OSTI ID:5292285
UNIX is a modern, popular, high-level language operating system running principally (but not exclusively) on PDP11 computers. One of the big problems with this system is a tight restriction on kernel memory due to the 32k word virtual address space of the PDP11. The work described here divides the kernel into modules that run in independent address spaces to overcome this problem. The main software effort was to develop software tools to make it easy to work with the seperate modules, and, where possible, to make the conversion without modifying the kernel source code. 1 figure.
