A new milestone for my little OS
-
I don't know - I haven't thought about names. I'll probably name it in a few months, when everything is more stable and functional. Until then, I'll just keep calling it Microkernel :)

Corn kernel?

For the challenge. I like being able to say that I've written my own operating system. The learning experience is enormous - from bootup to GUI, I'd have learned about time optimization, memory management, scheduling algorithms, (I'm using a lottery scheduler) graphical programming, file formats, BIOS interaction and in my opinion the most important part, reading manuals.

Yes I know, I keep wanting to get into things, but 2 kids and university studies keep getting in the way of things. I keep winding up my mate up who is forever dabbling with microcontrollers and building quad-copters etc. etc. that he has to much time on his hands and maybe he and his wife should think about having kids!

Waving? dave.m.auld[at]googlewave.comOh I know the feeling, my game engine has been put on the back burners for the same sorta reasons. But, I do respect those geeks intrepid enough to geek out on geeky stuff.

Some times while reading a manual I feel like reaching for an automatic. :-D

(note: I'm not ripping on you per se, just the concept of the phrase "you've got too much time on your hands") Why do people say that? If he had posted about how he had just won the NYC marathon after months of arduous training everyone would have congratulated him. If he had mentioned that he'd just made loads of money after spending vast amounts of time chasing clients, working on his company, etc, people would have congratulated him on what a great business man he was. But when someone posts about how they've just made some major strides in an intellectual pursuit (like developing an OS from scratch, or some artistic endeavor), they frequently get the "you've got too much time on your hands" comment. And it always seems to carry the implication that they should actually be doing something else. I know I've gotten comments like this regarding my framework, and my 3D projects. And seen other comments like these aimed at others in similar pursuits. I've found them vaguely insulting personally. It's as if people look down on this kind of thing. I don't get why.

When can we see a port of this for the iPad?

Because they're envious! :-D Marc

I've not been as active recently, and there's a good reason: I've been rewriting my OS. Previously, it was a chimera of lots of different ideas and thoughts. It also didn't have multitasking of any sort. I've taken a few pieces of code from it, and made a new microkernel. My microkernel just made it to ring 3 (not easy, since the only way to get into ring 3 is by making the CPU think that it was already there) and ran two tasks loaded from ELF files using multitasking. And I've discovered an elegant way of getting multitasking to work without setting up a timer driver :) So, yeah. All I need to do now is use some of my synchronization primitives throughout, get IPC working and flesh out some of my system calls, and the main kernel will be done. Then I can move onto user applications and drivers. The fun starts here.

ugh. that is sooo bad. but clever.

I've been designing it since last December, but I made my first commit on January 26th. Work actually started on the code on New Year's Day. At the moment, it contains exactly 4,460 lines of code.
