I was wondering about this ... there was a thread not too long ago about Darwin and FreeBSD. Somebody made the point that code seems to go into Darwin but no code is returned. It occurred to me that open source is like an ethical choice inasmuch as when one chooses the more ethical option theyre not always looking to further their own desires - sometimes they are simply shooting themselves in the foot.

Re: FreeBSD and MacOS
Here's an idea.. install FreeBSD 5.2.1 and use the ports collection to get PearPC. Then you can get a license to OSX and run it. I read the hardware support list, and sound doesn't even work yet in pearpc. It might be more beneficial to buy a used Mac. I have a FreeBSD desktop and an Ibook. OSX is very nice. Apple actually had a build of OSX that ran on ia32 hardware before 10.0 came out. It was one of the first release canidates. Apple kept it updated through 10.1 supposedly internally in case they needed to switch to Amd or Intel processors. Instead they chose the G4 and G5 chips. Thats how darwin was ported to x86 hardware. (well i think there was a version of next for pc hardware toward the end...) I'm going to try pearpc since I have 10.1, 10.2 and 10.3 install CDs. :) On Jun 29, 2004, at 4:01 PM, Martin Olsson wrote: Hi, * MacOS X is based on FreeBSD * there is a x86 kernel for FreeBSD Does that mean I can buy a copy of MacOS X, download an x86 kernel for freeBSD, do some (or quite alot of) hacking and then get MacOS X running on my PC?

You can Run Mac OS X or Darwin/PPC on FreeBSD w/ PearPC ( http://pearpc.sf.net ). And it's pretty slow at this point. Nothing like running MOL on Linux on PPC. You can Run Darwin/x86 natively on your PC ( http://www.opensource.apple.com , http://www.opendarwin.org). You can Run Darwin on FreeBSD on your PC w/ Bochs or VMWare ( http://bochs.sf.net ) Why would you want to use Mac OS X w/ FreeBSD anyway? The thing about all this emulation/virtual machine stuff is that you should ask, is it worth it? I've been thinking about running multiple BSDs on one machine for development purposes.

Could > it be done? Hm. Yes, that's possible. In principle, you have to write a PPC emulator to get the programs runnable, a Darwin emulation for the OS kernel [NetBSD might help there] and of course do a lot of testing. On a second thought, you might just emulate a full PPC like VmWare does. You don't really need FreeBSD for this, but having such software would be cool, so go on :) OS X is based on FreeBSD, yes. But the kernel is very different now and the greatest problems are (a) it's PPC and (b) most of the interesting stuff isn't really affected by the kernel. So if Apple would start to distribute e.g. OS X for IA32, yes, this would be a lot of work, but achievable. For PPC it surely can be done and NetBSD started something already. The biggest problem is likely to be the GUI support.

No flames please: Linux mknod compatibilty
Hi everybody,
First of all, please copy all answers back to me, since I am not anymore
subscribed to -hackers. (Panic: time fault)
I´ve done some changes to the kernel mknod(2) handling to make it more
compatible to the Linux behaviour, allowing one to create files of type VREG,
VSOCK and VFIFO with mknod(2). I already know that BSD way is that one should
use creat(2), bind(2) and mkfifo(2) functions for these, but, if all these are
indeed vnodes, why bother if one use mkfifo(2) or mknod(2) to create fifos??
The only vnode type I think I left out is VDIR, because it needs to be
initialized with "." and "..".
I first came with this idea using rsync for a full backup, noticing it
could not copy fifos or sockets. I could simply fix rsync, but I thought
"fixing" FreeBSD would be a little bit funnier! ;-)
To allow your appreciation, here are my patches. I am not an expert in VFS
coding, so it should probably be checked by an expert before commiting. All I
can say is that it worked for me.
I'll submit a PR after this email, to make it faster to commit.;-)

Well, right after you have taken the snapshot, it doesn't
require any additional space, because it contains just the
same data as the original filesystem. Similar to a hard-
link which doesn't take any addition disk space either.
But as soon as you start modifying the filesystem _after_
you have taken the snapshot, the snapshot will begin to
take up space on its own. For example, when you delete
a file, then its space will not actually be freed, but
taken over by the snapshot, because it still has to exist
in the snapshot -- you will not actually free any physical
space. Remember that the snapshot is supposed to contain
the data from the time when it was created.
Similar things happen when you modify a file: When you,
say, change a few bytes in a file, then the disk block
with the _old_ contents is copied and given to the snap-
shot -- then the modification is written to the original
disk block.
That mechanism is called copy-on-write. It means that your
snapshot's space requirement is growing all the time.
Removing files does not free any space, and modifying files
in fact reduces the free space, even if your modification
don't actually increase the size of the file.

No -- except, as I said, you'll run out of disk space,
sooner or later.
Under normal circumstances snapshots don't live for an
extended period of time. Typical uses include:
- Background fsck. This is done automatically during boot
without you having to do anything.
- Secure dump. You can take a snapshot and them dump it,
which is better than dumping a live filesystem.
- Short term backup. You can set up a cron which creates
and removes (i.e. "rotates") snapshots in certain inter-
vals, e.g. once per hour. This can protect against
accidental "rm" commands -- just copy the lost file back
from the most recent snapshot.
However, I fail to see why you would want to make 20 fixed
snapshots, automatically mount them during boot and keep
those same snapshots mounted forever.

Yes. See above.

Uhm, I think I read it 10 years ago in the manual of a
NetApp Filer. :-) FreeBSD's snapshots work very similar
to those of the NetApps.

It does't. First it takes zero space. When modifying the
original filesystem, the space of the snapshot grows.

"df" displays the current size of the snapshot (which is
zero in the beginning) and the total size of the original
filesystem, which includes any snapshots.

Have you actually tried that? And did the touched file
appear within the snapshot? I don't think so.
Note that you might be able to remount the snapshot with
-uw, but it doesn't actually change anything. You still
cannot write to it.
You can also mount a CD-ROM (cd9660) read/write -- and
yes, I have tried this. ;-) You do

Back on the days of using FreeBSD 4.6-Release, i once wrote a simple
program to get MAC address of a specified NIC. I tested it on -current
just now. Still works fine. =)

PCI memory alloc..!
Hi all, While I was trying to track to find out how a device alloc a new memory resource, I have been little confused on finding out how the new PCI device can deal with a case when the activation calls pmap_mapdev What I need to understand that what will happen if pmap_mapdev allocated a new space that dose not match what is expected by the device and determined by r_start and r_end ??
