Minix3 under linux

[Ladislav Klenovic]

Hi all,
I have "ported" minix-3.1.2a to linux. I would like to use minix3
as starting the point for my micro-kernel called nucleos.

Port includes following components:
- boot monitor
- kernel + servers
- installboot utility (some modification performed)
- most of the libraries except ACK, related sources and most of
16-bit code (only string routines).

What is new:
- build under linux by using gnu toolchain (gcc, ld,...)
- source code reorganization
- linux like build-system + kconfig utility (so you use
cool make {menuconfig, xconfig,...} now :-) )
- ack asembly rewritten to gnu as.
- useful tools:
* creating minix3 filesystem on images (via loop device)
* converting elf32 to minix's aout (needed until turn to elf
format)
* script to install bootblock, boot, kernel and servers on image
- everything what was needed to make the port :)

I have tested it under qemu and vmware so far and looks quite stable.
These days I am upgrading to trunk and hope will provide with some
results soon.

Regards,
Ladislav

Hi Ladislav,
That is really good news!!! ... I've been working on this myself and
had got to the point of having the core tasks up and running. I had
made changes for minix to be loaded by GRUB. I could not work on it
beyond that (still in my todo list). http://github.com/ckkashyap/newminix/tree/master

Is there some place I can download your port?

Regards,
Kashyap

I will place it on my site and make an announcement here. I am
planning to do
so on Sunday.

GREAT JOB!! Expect to build minux on linux! Where can I get the source? I can't wait it! :)

You can download the first aproach from the following URL:
http://nucleonsoft.com/project/nucleos

The port includes following components:
- boot monitor
- kernel + servers (except `is' server)

- installboot utility (some modification performed)
- most of the libraries except ACK, related sources and most of
16-bit code (only string routines).

- drivers which are needed for ramdisk hovewer you must create the
ramdisk manualy and then compile it into memory driver :(

What is new:
- build under linux by using gnu toolchain (gcc, ld,...)
- source code reorganization
- linux like build-system + kconfig utility (so you use
cool make {menuconfig, xconfig,...} now :-) )
- ack asembly rewritten to gnu as.

- routines for 64-bit size manipulation need gcc's library
`libgcc.a'
(should be found by build system automatically)

- useful tools:
* creating minix3 filesystem on images (via loop device)
* converting elf32 to minix's aout (needed until turn to elf
format)
* script to install bootblock, boot, kernel and servers on image
- everything what was needed to make the port :)

Read the instructions on site (or doc/getting-started.txt) about how
to configure, build etc. the kernel.

Ladislav

Hi! This is a very impressive list! I believe you are using linux's
kbuild system for menuconfig. Can you please point me to its sources?

Thanks

Hi,
yes you are right I use linux's kconfig however only a few
config. option are used for now.

Sources are available on: http://nucleonsoft.com/project/nucleos

Ladislav,

 

Really cool accomplishment! I got your code and tried to compile it on my Fedora 7 VM. It ran smootly until reach the init/ash step on the build. There it blew up complaining about the non existence of init.c. I looked around and this file with the functions defined in it's init.h doesn't exist. My questions are: the mktools mkinit should create the init.c on the fly? If no, how it's created? Can you give me directions to solve this? Any other tips to this issue?

Thanks a lot for your time and keep the good work!

Hi,
yes you are correct the `init.c' should be created on fly by `mkinit'.
I have to admit
that I have compiled sources only under openSUSE. What comes to my
mind
regarding this is:
* Were the `init/ash/mktools/mkinit' binary built successfully?
* Is the version of `make' utility 3.81 (I guess yes)?
* Could you paste the error message here (lines between the last
successfully
build target and where the build process stoped)?

Besides that if you are not planning to change the `sh' inside image
you can simply
avoid to build `init' directory. So move to `init' directory and
remove `ash/' and
`simple/' from Makefile (from `obj-y')

Please do not forget to read `Getting started' and follow the steps
there.
Thank you for reporting this maybe some patch will be necessary.

Regards,
Ladislav
