I was tired to read 4000000 lines of Linux kernel to learn.
I did write 1500 lines "nanokernel" for more easy learning just the basics. At least I did try to make some effort for documentation.
It is not a full scale operating system (simulated no device drivers) at all but includes:
Documentation and download :
- priority based scheduling- pre-empive for set of test tasks (newest version also round robin)
- example of context-switch, interrupt handlers....
- TLB- fault handling
- very simplified demand paging
- 17 system calls mainly for inter process communication (IPC)- embedded system style approach (semaphores, message passing....)
- shared memory for IPC
- fork call
This site do not seem to support links????
The processor can be exotic but the principles are always the same.
