Re: What do people think of maybe using the sourceforge software?
Second, the projects page we have now, with all due respect to the people that try to keep it reasonably organised, is a mess due to the lack of updates. people only maintain their project pages perhaps, but certainly not the links that lead to them. Being able to work with more people on the same project on an equal bases would be a good idea IMHO. Well, I have to say that I installed and played with sourceforge for awhile and it's, well, highly dedicated to being sourceforge. The various product links *all* point back to sourceforge.com relative addresses and there's no concept of "$PROJECTNAME" or "$PROJECTBASE" to customize the sourceforge software for someone else, like the FreeBSD project. It's very much an example of a "code straight to the goal and for one purpose" implementation and, unfortunately, thus completely unsuitable for our purposes without some major hackery. Maybe if we could find something else... - Jordan To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

The cards and the driver you mention is the old ATM implementation made by Chuck Cranor (sp?). There is much newer and much more sophisticated framework called HARP, which is part of FreeBSD beginning with, I think, 3.0-RELEASE. HARP supports (among others) Fore PCA-200e card which I use. See the docs in /usr/share/examples/atm. NOTE: this card requires loading a firmware each time it's initialized (after reboot). The firmware has to be _exactly_ the version that is mentioned in the HARP docs, because HARP drivers refer to locations in the binary image.. Also, be sure to set proper encapsulation on both sides of your link (e.g. LLC/SNAP). Other than that, the card works perfectly ok for me.

How to make system Sync
I had a couple of system out of sync problems.
(1) PCI sync problem:
ATM adapter updates a buffer return pointer and generates intr,
but when driver pulls out the information that updated by adapter,
some memory in the last piece of the pool is garbage.
e.g.
head - c010
tail - c0100400
c010 - buf0
c014 - buf1
...
c0100100 - bufn
...
c0100160 - bad address or 0
...
If I let driver tsleep() for a while, the problem can be improved.
So, it looks like that adapter pushed (DMA) the data into memory,
but not been seen by CPU right way due to the DMA sync issue.
How can we sync the DMA transaction in BSD?
(2)
page fault trap does not show up right way:
at #7, lock_ObtainSpin is defined as simple_lock(). Before this line,
I put a line code --
char* psp = panicstr;
to save the panicstr status, and we can see psp is NULL; i.e., "page fault"
has not been trapped yet. Where a few instructions down to tsleep(),
the panicstr is set to "page fault", but there is no code in the function
_simple_lock() can cause page fault. So, the page should be happened at
earlier time somewhere.
For this problem, how can we enforce the page trap show up at right spot
to catch the problem?

well this is what i am doing:
i have a device buffer in contiguous physical memory. i want to write
that buffer into
a file disk. for that ive written a simple ioctl which works similar to
the syscall
write. except that it transfers from kernel space instead of user
space. my user
program calls this ioctl with the write file descthe ioctl calls
fp-f_ops-fo_write after setting up the uio to do the transfer.
earlier the user code looked like:-
fd=open("/dev/mydev",O_RDONLY);
buf=malloc(BUFSIZE);
read(fd,buf,BUFSIZE);
w_fd=open("foo",O_WRONLY|O_CREAT);
write(w_fd,buf,BUFSIZE);
now the user program looks like:
fd=open("/dev/mydev",O_RDONLY);
ioctl(fd, MYDEVREAD, size);
w_fd=open("foo",O_WRONLY|O_CREAT);
ioctl(w_fd,MYDEVWRITE,size);
as a result of this the copy involved in the first read is eliminated.
but it takes
longer to do the 2nd ioctl than to do the write.
if this does not explain what i am doing please let me know.

Cisco Port Grouping w/FreeBSD
Hi, I have a question for the networking gurus out there. How exactly would you configure a FreeBSD machine connected to a Cisco switch with port grouping on two Ethernet channels? Also, for future reference, the funny network delays on the switched network were solved. It turns out if you force the switch to 100/full on the port, the Intel PRO 100/B card will run at 100/half, since it assumes the switch is a non-autonegotiating hub. Use auto select on both sides works very well.

Re: smb printer trouble
I know it is happening because of the ``read firstline'' command. It is using the standard shell way of continuing a line using the '\' char and applying that to the input. That explains why only the first line is effected. Actually, if there is a way that I can read only the first two chars from the standard input that would solve the problem for nearly all the cases. I only need the first two chars to do my test, then I can leave the rest up to cat. It would be even better if sombody could tell me a way to push chars back on to the stdin stream that way I can completly avoid making a temporary file.

boot/kernel debugging
I've used softice for debugging under windows, and i was wondering if gdb offers similar capabilities. It seems the best way to debug the ECP parallel port problem is to step through the code during the boot phase. Can this be done, or is there too much timing-critical stuff going on then? jm -- --- Jonathon McKitrick -- [EMAIL PROTECTED] I am a bomb technician.

modules and newbus
I got the impression that newbus would make it easier to make kernel modules out of things. What in general does it take to make something into a kld? I'm thinking of pcm for example. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
Re: leaking sockets (closure)
Hi Mike, On Wed, 17 May 2000, Mike Silbersack wrote: Heh, that's sorta neat, I guess. It'll be interesting to find out if the leak is due to the mbuf waiting in some way, or a totally unrelated bug we're tickling. I'd almost guess the latter. I finally peeked at the tcp_timer stuff and quickly realized: `grep keepalive /etc/defaults/rc.conf' or, equivalently, `sysctl -A | grep keepalive' should quickly make things clear... :-) Notice the explicit initialization of always_keepalive to zero in tcp_timer.c, which is what at first glance tripped me off. (I have re-simulated the exhaustion and all seems fine). -Bosko -- Bosko Milekic * pages.infinit.net/bmilekic/index.html * www.technokratis.com [EMAIL PROTECTED] * [EMAIL PROTECTED] * [EMAIL PROTECTED] "Give a man a fish and he will eat for a day.

Re: modules and newbus
Just as a quite spot note... Im near completion on my KLD programming tutorial... Just got to push out a section or two more and then wait for a review and it will be ready for relaease. This will/should help many with their general questions regarding how to write KLDs and hopefully willhelp with questions regarding "is it useful to write a KLD"..

Musings on ip checksumming
I'm trying to write a simple static NAT, and have got a bit stuck with the new checksum in the IP header thing with me is that I'm not happy about something till I understand it (and it appears that the IP stack is well behaved and won't send something unless the IP checksum is right either). Looking into ping.c for an example we have a checksum calculator (in_cksum) that I have been trying to understand. It takes a header and adds all the 16 bit words to a 32 bit acumulator. Fine. It then takes the top 16 bits and adds them to the bottom 16, (adding an additional one if this operation itself takes the resulting number to 17). Not what I understand as a checksum, but none the less a perfectly valid algorithm. What I *don't* understand is this: The routine appears to be written as if would only work on a big endian system i.e. this would only work if u_short's and int's were stored most significant byte first. This impression is further underscored by using 16 to fold the top 16 bits into the lower 16 bits. The pile of htons calls and ntohs calls I was expecting to see is simply not there. So, how come it works?
