I'm having some trouble adding a bus resource and am hoping someone
can point out where I goofed.
The host bus to a new x86 chipset has a memory mapped region in PCI
space that provides
possible bus, device, function number combination. I was thinking that
each of these segments was a bus resource, but maybe that isn't the
right approach. Any thoughts as to a better approach?

Below are links to the sparc64 port I've been working on, which

Ok, sometimes we find a bug in a particular release where what's
needed is a function replaced with fixed code.
I'm wondering if it's possible to:
1) look at the kernel symbol table for a particular function in a
particular object file (static functions would be even better?)
2)
Can we kill these syscalls? They are not used anywhere in the kernel and
although they have wrapper functions in libc, no header contains prototypes for
these wrappers. According to the CVS log they were originally brought in for
POSIX threads and AIO, neither of which use this facility.

Jordan said that the kernel SMP thread is ready in CURRENT FreeBSD,
but I could not find any document for the SMP kthread.
By looking at the kern/kern_kthread.c code, it does not look like a SMP

I have:

If the daemon can somehow reside entirely inside the kernel, like NFS

How do I set up a system call of my own in the FreeBSD kernel?

That's better. It appears to be a classic resource related deadlock that

free up pages), but is unable to since no memory is

Hi,
I spent most of the day recompiling X and what not.
All the patches applied cleanly, there are some rejects with MESA,
but I think that has to do with tags and comments at the beginning of
files.
Everything compiled fine, and the module loads, now I just need to
