Hi there,
The basic reference would be the original book by Pat Villani. There is the little problem that the kernel has grown too much ever since. Time ago I had been reading the kernel sources, as much as to get an idea on how it works. I planned to create some block diagram, but didn't have time for it. I have a preliminary one that I created, but it is quite preliminary, may have errors, and that I use as a simple reference, I attach it in case you find it useful. Just one thing to be corrected, "MEMORIA" is the Spanish for "MEMORY" and "Dispositivos" are "Devices". The diagram is incomplete. There are also some files there missing: - Related to process support (PROCSUPT, TASK) - Related to interrupts and stacks: IRQSTACK, DOSIDDLE, ENTRY, INT2F, INTHNDLR - Related to initialisation: DYNINIT, INITHMA, INITOEM, CONFIG, MAIN, KERNEL - Miscelaneous support files: APISUPT, ASMSUPT, PRF, IPRF, STRINGS, MISC, GLOBALS, INTR, NLSSUPT, SYSPACK I hope to have time some day to write a decent, COMPLETE, and proper one (and perhaps some docs). In the meantime, questions are welcome. I hope that helps.
