This is very Unix-centric. Day 01, Processes, ignores interesting alternatives, like OpenVMS, which have radically different memory layouts, and things like "images" getting loaded into a common address space.
Mach would be another alternative to consider.
- rlupi 2y agoThat's quite interesting. Do you have any resource to recommend for OpenVMS or Mach architecture overview, or in general OS architecture tradeoffs and designs?
- bediger4000 2y agoI'm basing my VMS process memory layout comment on: Virtual Memory Management in the VAX/VMS Operating System by Henry M. Levy and Peter H. Lipman, Digital Equipment Corporation. It's an old paper, but I believe, still essentially correct. I looked into Mach circa 1991, when I had a NeXT. The NeXT OS was based on Mach 2.0 as I recall, perhaps current Darwin docs will help there. I don't have any preferred modern references. Googling for "Mach operating system" pulls up quite a few.
