SeaKernel 0......I forgot the version number.

So, I have gotten SeaKernel to a point OK-ness. It's Pre-0.1.
It is based off of JamesM's tutorials...
Heres a floppy:
http://seakernel.googlecode.com/files/floppy2.img

It executes program 'init' in the initrd which does nothing except waits for you to type 'die' and press enter. It then exits with code 12.

Heres a happy little link to the main page...

Test it, see if it works...

It works. So, the paging doesn't triplefault for you, eh?

Anyways, what direction do you intend to take SeaKernel in? A lot like Linux or a little like Linux?

Similar, a little. I'm using some ideas from Linux 0.01 (easy to read).

What do you mean 'bout the paging?
HA! Successful on QEMU, Bochs and VMware!

I just tried it in VPC '07. Here's the output:

Code: Select all

Loading kernel...
(welcome)
Init running @ PID 1
Running init...
Child died with code 0

[BUG] We would normally reset here.

About the paging: Eh, I get triplefaults with any paging implementation, including JamesM's.

I'll have to test it on a real machine......

You do? Huh.....I only get that when I run more than 14 or so tasks.....
It has something to do with the init_paging() function, the heap isn't big enough I think.

I just booted Sea on a real machine (512MB of memory, no hard drive, old Athlon). It works.

On an Athlon? Thanks!

I got it working on my old Intel P2....so I'm pretty happy..

No problem.

I could bring in my old Pentium box from the garage and give it a go on that, too, if you want.

It ok.....I think it's been tested enough for now.
Now I have implemented pretty much everything it does into system calls....

Okay, cool. Good luck.

Here's a small update, including usermode, stacks and a scheduler update:
