This replaces the previous virtual address allocator which was basically just "m_next_address += size;" With this in place, virtual addresses can get reused, which cuts down on the number of page tables created. When we implement ASLR some day, we'll probably have to do page table deallocation, but for now page tables are only deallocated once the process dies. |

Serenity
Graphical Unix-like operating system for x86 computers.
About
I always wondered what it would be like to write my own operating system, but I never took it seriously. Until now.
Serenity is a love letter to '90s user interfaces, with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.
Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by me, for me, based on the things I like.
If you like some of the same things, you are welcome to join the project. It would be great to one day change the above to say "this is a system by us, for us, based on the things we like." :^)
I regularly post raw hacking sessions and demos on my YouTube channel.
There's also a Patreon if you would like to show some support that way.

How do I build and run this?
Go into the Toolchain/ directory and run the BuildIt.sh script. Then source the UseIt.sh script to put the i686-pc-serenity toolchain in your $PATH.
Once you've done both of those, go into the Kernel directory, then run makeall.sh, and if nothing breaks too much, take it for a spin by using run.
Otherwise, see the older step-by-step guide to building Serenity
