Take a look at gcore. That will let you checkpoint memory mappings and
registers. The dragonfly implementation also keeps track of the sbrk
value and open file handles which you will need to handle separately.
Restoring the mappings and register state should be straightforward.
I'm not sure at how

Yes I did, and I added an API to query it more generally. I didn't add
it to net/flowtable.c because my usage seem
You're right. A write memory barrier is needed there.
Thanks

If the value lags next by one then it is ours. This rule applies to
all callers so the rule holds consistently.

I can't comment on whether or not it is good or
Just add them to the makefile. They'll be automatically created as
dependencies.

Have you taken a look at lldb? It is designed to be more modular.

All 10GigE NICs and some newer 10 GigE NICs have multiple hardware
queues with a separate MSI-x vector per queue, where each vector is
directed to a different CPU. The current operating model is to have a
separate interrupt thread per vector. This obviously gets bogged down

Look at the posix shmem and sem functions:
shm_open
shm_unlink
sem_open, sem_close, sem_post etc.

See my page now. It contains a pointer to a tarball
with what I believe to be the appropriate style
patches and a single unified diff. I'm obviously new
to this so humor me and let me know if there are any
further problems.

It turns that this problem is specific to AIO in
-CURRENT. I wrote a simple program that uses
the three different completion mechanisms (polling
with aio_error, polling with kevent, and using SIGIO)
to fill up a file by writing 8kb at a time to the
file and then reading 8kb at a time from the fil
Has anybody used AIO in conjunction with kevent?
I am seeing as much as a 12 second latency between
when I do an 8k aio_write to a file on local disk
and kevent returning its completion (I'm calling
kevent every ~20ms). Using regular writes works fine,
but this is a multi-threaded application so
Not to mention that SIGVTALRM is already used by
the thread library (although I would hope that
_thread_sys_sigaction is smart enough to handle
that case). I've stepped through the GDB
code on both 4.18 and 5.1. On 5.1 I found the
following in i386fbsd-nat.c:
void
child_resume (ptid_t ptid, int
msg = sk_receive();
if((msg->type == SK_SIGNAL_MSG) &&
(msg->data.l == HARD_SIG_00010))
break;
} while (1);
sk_remove_poll_fd(slot);
}
beneath this it just uses poll

Any idea why when I insert a breakpoint I get a
SIGTRAP
and can't continue any further? Is this a bug in the
FreeBSD distribution's gdb? I don't see this behavior
on any other platform that I am using. (Linux/
Solaris/
OSF1)
I am only seeing on this particular application. The
