Basically if you're using ioapic (and you are), OpenBSD maps the lapic_tpr to the special TPR register to block interrupts everytime you get an interrupt of raise it yourself by splraise()/spl* and so on. You don't suffer this on amd64 since the masking is done purely in software. You can also verify this statement by disabling mpbios on OpenBSD and falling back to the old pic controller, in this case you don't use ioapic, and the pic code does the mask in software, lapic_tpr is still the same variable being touched, but in this code path, it's not mapped to the cpu TPR. To have an ideia of the cost of touching the tpr: real hardware: ~25 cycles. kvm + flexpriority (cpu extension): ~2700 cycles. kvm without flextpriority: 100k+ cycles. So every interrupt you take needs to touch at least lapic_tpr twice, which before would cost ~50cycles, and now it's more than ~200kcycles. Of course these numbers are relevant to the machine I've tested, but you get an idea on how much slower it is.

Here your test is probably botched, you're probably just stressing one queue from the card, which gives you more or less what you're seeing, you need to send multiple tcp/udp streams, then you can have an idea how much linux/freebsd can do. obs: "we usually count forwarding rate, so when you say 15gbit/s, most people say 7.5gbit/s =)" > > Are there tuning options that we've not seen yet?

It's less code, and code gets copied, and people don't read docs, they
copy code and cross their fingers, we shouldn't incentivate that.

Re: Calomel.org
I feel this usually comes from folks with Linux background. You see, in BSD world, specially in OpenBSD, there is good and high quality documentation, which the developers put a lot of effort in providing it. I know, since I did it too in the past, that when you're using Linux, you're basically in the dark, so you go to google, and you try your luck. Everytime you follow a non official documentation, you waste your time and the developer's time, we're not cranky about "calomel" only, we're cranky about people following unofficial documentation, remember, our FAQ and manpages are accurate 99.99% of the time and they are pretty well written and complete. If you can't figure it out by reading the FAQ/manpages: you're either not ready for it, or we have a documentation bug.

OpenBSD web page: - It's small - It's simple, just basic HTML, some cgi, nothing fancy, all very easy to maintain. - You find anything in less than 1 minute. - It looks nice, since that is how webpages should look like (IMHO). If you really wanna improve that, I'd suggest reworking the same webpage, but making it possible for people with vision impairment to use it more effectively, I've been told that there are a some ways to improve it.

One small task I used to pass to people wanting to learn C, is to implement a strtok-like function, they could design their own API. It is interesting because they need to deal with pointers, strings, and design an API as in: - should I pass a fixed array and alloc all tokens ? - should I return an alloced "structure" ? - should I modify the string in place as strtok ? should I copy. A lot of decisions have to be made, and it's interesting to see how they approach it.
Re: OpenBSD forked
Tedu's suggestion is the best one in my IMHO, implement a webserver. I would try to do the following: - Read K&R - Join ##c on freenode, they can help a *lot*. - Read manpages of every function. - Code small UNIX utilities, start with cat, then wc. - Code something like a webserver, this is where you'll actually learn.

Can you try the following diff ?
The identifycpu diff caused a problem on acpi resume but it was fixed,
this reverts the whole thing.

Thanks for the port, I had to tweak a bit to compile on an ancient

Now do 300mpps * 1500bytes, that's your throughput for full sized packets.

I think that is not the case here, by default we do not enable em(4)
checksumming offload.
Just to make sure, can you give me the output of 'if config
em{0,1,2,3} hwfeatures' ?
I think pf is not recalculating the checksum after nating, not sure if
it should, henning ?

You can still use -j8 while building the kernel though, no races there.

char rdata; /* 12 + 16 */
} __attribute__((packed));
The thing is that GCC knows rdata is 1 byte long, you're doing the
magic here if I'm correct:
/* skip dns header, question name, qtype and qclass */
answer = (struct answer *)(&reply[0] + sizeof(struct dns_header) +
q->hdr->namelen + 4);
You can remove the __attribute__((packed)) and turn rdata into "char
rdata[]".
Or just get a pointer past sizeof(answer).

Hi again,
Could you try the following diff ?
Please remember to undo the modifications of the previous diff.
The thing is in_proto_cksum_out() correctly escapes hw checksumming if
the interface is a member of a bridge, the same should be done for ip
checksums.

You clearly have no idea what you're doing, and instead of learning you go to public bashing, no one is forcing you to do anything, and we've provided excellent documentation about the upgrade process. What amazes me is that upgrading is one of best things about OpenBSD, devs put a lot of effort into doing it right, and yet there are types like who come and say whatever crap they feel like to. I've started using OpenBSD in 4.2 and been upgrading since them. I *never* had an issue. There are a lot of people out there doing since much much much older releases. Insan: As for the original question, no, you should have no problems. We all run a bunch of amd64 machines and upgrade it constantly, if not daily. Please report back if you have any troubles.

Re: Packet drop because of invalid IP checksum on Soerkis / vr / ral
I think I've found the problem. when a packet comes from ral0 ---> 10.0.0.1, the bridge changes the received interface to vr0, which has IFCAP_CSUM_IPv4. So when the icmp layer is about to test the checksum, it assumes the output interface is the same one which the packet came in (in our case, vr0, and not ral0). So the checksum does not get calculated. That's why it works when we remove the capabilities from vr0.

I'll come up with the correct fix, this is just to confirm our initial

I'll send it to you as I don't have a vr(4) to test.

You have to paste the output of dmesg and usbdevs before people start considering helping you, until then you're just wasting everybody's time. All your mails lack information, you don't say what you are trying to do, what you already did, what worked, what didn't work. Then you provide no dmesg, and no other output which may convince someone to take you seriously. This is not the first mail people tell you that. Have in mind, you're doing everything to convince people *not* to pay attention to you.

Can you paste a dmesg ? There was a bug in 4.8 I believe, maybe it snapped into 4.9, I can't remember. The thing is you can't enable checksumming in software, and you shouldn't, if you're re(4) for some reason can't do offload checksumming, we should be able to detect and disable. By now we enable hw checksumming for all re(4): sys/dev/ic/re.c:1133 ifp->if_capabilities = IFCAP_VLAN_MTU | IFCAP_CSUM_IPv4 | IFCAP_CSUM_TCPv4 | IFCAP_CSUM_UDPv4;

setsockopt is failing in:
while (setsockopt(s, SOL_SOCKET, SO_RCVBUF,
(void*)&bufspace, sizeof(bufspace)) < 0) {
if ((bufspace -= 1024) <= 0)
err(1, "Cannot set the receive buffer size");
}
if (bufspace < IP_MAXPACKET)
warnx("Could only allocate a receive buffer of %i bytes
(default %i)",
bufspace, IP_MAXPACKET);
Did you tweak any sysctl options ?
Is the machine loaded ?
I think sbchecklowmem() may be failing in uipc_socket2.c:403.
Also ping should use warn() instead of a warnx() there.

Re: WiFI and VGA issues with Dell E6320
It seems you've no drm ?

Without drm, opengl will be painfully slow, you probably don't have
Xvideo also, try xvinfo (no nice playing in mplayer).
I'm no expert so I might be wrong.

The links were fine, I checked them.
Also although I had an azalia0, I had no audio at azalia0, so the
audio links couldn't be wrong I suppose.

Re: No sound with ATI SBx00 HD Audio
I found out the datasheet for 0x4383 http://developer.amd.com/assets/43009_sb7xx_rrg_pub_1.00.pdf I've no knowledge of PCI to debug it though.
Re: No sound with ATI SBx00 HD Audio
Now I've noticed some popping sounds between which seem to alternate between
speakers, but still no sound.

Re: Laffs with Lennart
Lennart is a funny, funny man, go check the avahi code to see how nice it is. " When working on Avahi I learned a lot about the complexities of safely and reliably running and maintaining system services, and about securing them as much as possible, which is particularly important for network facing services like Avahi. I implemented a lot of pretty nifty features in this area in Avahi. For example, Avahi is still pretty much the *only daemon* on a standard Linux install that chroot()s itself by default.

Very strange cvs performance.
Hi there, I have a local mirror of cvs src, everything works fine, except that the IO seems to take place in another disk. I have a very very very very slow udma controller in wd0 (the ultra 5 one): wd0(pciide0:0:0): using PIO mode 4, DMA mode 2 So I keep my cvs in a faster controller/disk: wd1(pciide1:2:0): using BIOS timings, Ultra-DMA mode 7 I have this, so you can see, most stuff is on the slow controller. /dev/wd0a on / type ffs (local) /dev/wd0d on /tmp type ffs (local, nodev, nosuid) /dev/wd0g on /usr type ffs (NFS exported, local, nodev) /dev/wd0e on /var type ffs (local, nodev, nosuid) /dev/wd1a on /data/sta type ffs (NFS exported, local, nodev, nosuid) Here is the weird part, /cvs points to /data/sta/cvs (which is in the fast controller) lrwxr-xr-x 1 root wheel 14 Jul 13 19:55 cvs@ -> /data/sta/cvs/ Now watch what happends when I 'cvs up' from another machine: == No cvs up, disk mostly idle == gandalf:haesbaert: iostat -w 3 ttywd0 cd0 wd1 cpu tin tout KB/t t/s MB/s KB/t t/s MB/s KB/t t/s MB/s us ni sy in id 0 41 11.68 3 0.03 0.00 0 0.00 49.91 5 0.25 1 0 2 1 96 0 74 0.00 0 0.00 0.00 0 0.00 0.00 0 0.00 0 0 0 0100 0 98 13.71 7 0.09 0.00 0 0.00 0.00 0 0.00 0 0 0 0100 == cvs up, wd1 transaction should go up roof == gandalf:haesbaert: iostat -w 3 ttywd0 cd0 wd1 cpu tin tout KB/t t/s MB/s KB/t t/s MB/s KB/t t/s MB/s us ni sy in id 0 41 11.68 3 0.03 0.00 0 0.00 49.91 5 0.25 1 0 2 1 96 0 98 9.52 263 2.45 0.00 0 0.00 0.00 0 0.00 5 0 9 3 84 0 25 9.53 277 2.58 0.00 0 0.00 0.00 0 0.00 1 0 5 0 94 0 49 9.51 282 2.62 0.00 0 0.00 0.00 0 0.00 2 0 7 1 90 0 49 9.67 258 2.44 0.00 0 0.00 64.00 0 0.02 1 0 5 1 93 But no, IO seems to take place mostly in wd0, I've confirmed swap was not taking place, I shut down everything, top showed 100mb+ free: load averages: 2.23, 1.02, 0.65 gandalf.midearth 03:12:25 42 processes: 1 running, 40 idle, 1 on processor CPU states: 1.6% user, 0.0% nice, 4.9% system, 0.4% interrupt, 93.2% idle Memory: Real: 19M/64M act/tot Free: 176M Swap: 16M/1024M used/tot The user doing the cvs has a home in /home/ which is in wd0. I'm also able to hear wd0 (different sound than wd1), so I know fstat is telling the truth. What's hapenning ? I'm pretty sure I'm missing something real simple, just to have an insight, a 'cvs up' is taking more than 30min.

Thanks a lot.
Re: nat6 to nat4
Thanks a lot, I'll read it with love. Is there any other alternatives I should know of ?
