mini-os (not a cross post)

[Donour Sizemore]

Hi everyone

I just posted to xen-users about not being able to build
the mini-os example. Looking through the souce I found a
big

 * TODO - x86_64 broken!

in extras/mini-os/include/hypervisor.h. Does anybody know
exactly what the issue is that keeps it from building?

thanks

I did a quick fix of replacing the hypervisor.h contents with
code from the sparse kernel's corresponding file.  This along
with a couple of other minor changes got it to compile.  But
it doesn't boot up properly.  I'm investigating that a bit in
my spare time.

Thanks for the tip. I'll take a look at it shortly.

Were your you trying to boot it on a 64bit machine?

Yes, on x86_64.  One possibility is that the
mini-os I built was from the recent unstable source, but my dom0 kernel
and hypervisor were built from older sources.  There is probably an
incompatbility there.  I'll try again using consistent versions when I get
the time.

Let me know what you find.

Hi there guys!

I am currently responsible for mini-os. I've recently updated the code 
to make it work under 32 bit (mini-os was not used for quite some time, 
almost 2 years if I am correct. Subsequently the changes in the 
interfaces broke it).

I've started fixing 64-bit version as well, but now I am busy with 
something else. It will therefore have to wait a little unless you are 
interested in helping out. I could give you precise list of things than 
need fixing is such case.

Cheers
Gregor

Gregor,

I think I could spend some time helping out on this.  If you could
post the items that still need work, I'll choose some items to work on.

Thanks!
Dave

Yes. Could you please send out that list. I'm still interested in getting
it working.

I tried this with recent unstable-source, but ran into quite a few
other errors. Specifically, this one has me perplexed:

/usr/include/linux/types.h:34: error: conflicting types for `size_t'

I didn't think that could happen has the x86 and x86_64 hypercall.h
are the same (at least in the linux-2.6-sparse directory).

Did you make any progress since the booting errors?

err, hypervisor.h

Donour,

I haven't had time yet to really look at it. I'm hoping to have a few
hours this week.  I'm also waiting for Grzegorz Milos to post a list of
items that need to be worked on in x86-64 mini-os, and I'll try to
start working on that list.
