Hello, This sort of tuning you're discussing really depends on your particular system. What are you running, what's your system doing, and are you seeing any problems? For the most part, the sysctl interface lets you tune everything.

Re: SSE bcopy
I don't think there will be a problem with releasing my source code. That is, if it works and is truly a performance win :) There are some PDF docs available on Intel's web site that have sample code for an SSE bcopy, and give performance results (in particular, Block Copy Using Pentium III Streaming SIMD Extensions). It seems to be about 60 - 80% faster than using MMX instructions. However, when you use SSE to store data in the destination memory location, you bypass the processor's caches. So, if you were to touch the data soon after the bcopy, it is no win at all. For what I'm trying, I'm not going to be touching the data, so it's ok. However, it may only be useful for freebsd in general as an alternative to the existing bcopy. Also, there is the hairy issue of saving the FP state before using these registers. Intel's paper describes a way to do this where you don't have to save the entire FP state - just 32 bytes of it. Thanks for your help, folks. I'll give the patch a try.

Re: FreeBSD Advanced tuning advice
Yes, but every time I've seen those brought up, the high-level hackers here say Don't do that. :) If we could get a definitive answer on acceptable flags, I'll put it in the FAQ. Basically (although I'm not a high-level hacker) what I've gathered is that -O optimization above -O (without a numbeR) isn't supported because there are known bugs in gcc opts above -O (and it's questionable whether or not they actually improve performance). Also, I know in a lot of cases the -march opts don't really do much either. In some cases doing -march=pentium actually produces faster code on current systems than doing -march=pentiumpro (or -march=i686, these are the same thing). So basically my recommendation is that no matter what you hear from linux people (just saw an article on slashdot, and the guy said he compiled the whole gentoo linux system with -march=i686, which really doesn't increase performance much ) say about these opts, they don't really help.

Is natd the right tool?
Natd is a very cool tool for doing stuff like redirecting connections from an external network to an internal one but I'm have a slightly different problem. I have a single host with one public interface:
host - fxp0 = 192.168.7.251
Also on this same host is a bunch more IP's on the loopback interface:
host - lo0 = 127.0.0.1
127.0.0.2
.
On each of the loopback addresses I have a DNS server listening. This part works just fine:
matt@matt: {101} % dig www.foo.com @127.0.0.2
verbosity snipped>
;; ANSWER SECTION:
www.foo.com.1D IN A 207.89.154.94
What I want to be able to do is send a dns query to the external interface of the machine on a non-standard port and have it redirect the query to a loopback address/port and return the query the appropriate query result to me.
So, after reading the man page several times, I've tried using natd like this:
natd -n fxp0 -redirect_port udp 127.0.0.2:53 192.168.7.251:55
However, doing so simply get's me a connection refused when I send it a query like this:
matt@matt: {102} % dig -p 55 @192.168.7.251 www.foo.com
; >> DiG 8.3 >> -p @192.168.7.251 www.foo.com
; (1 server found)
;; res options: init recurs defnam dnsrch
;; res_nsend to server 192.168.7.251: Connection refused
matt@matt: {103} %
I'm not exactly certain why it's failing. Is this the best approach to solving this problem? Is there a better way to go about this?

Re: SSE bcopy
Denis Serenyi writes: I don't think there will be a problem with releasing my source code. That is, if it works and is truly a performance win :) Cool! There are some PDF docs available on Intel's web site that have sample code for an SSE bcopy, and give performance results (in particular, Block Copy Using Pentium III Streaming SIMD Extensions). It seems to be about 60 - 80% faster than using MMX instructions. However, when you use SSE to store data in the destination memory location, you bypass the processor's caches. So, if you were to touch the data soon after the bcopy, it is no win at all. Hey, that's great! The copies I care about are in situtations where the data is not touched until much later, so the normal copy is typically a big loose because it blows out the cache..

Natd is a very cool tool for doing stuff like redirecting connections from an external network to an internal one but I'm have a slightly different problem. I have a single host with one public interface:
host - fxp0 = 192.168.7.251
Also on this same host is a bunch more IP's on the loopback interface:
host - lo0 = 127.0.0.1
127.0.0.2
.
On each of the loopback addresses I have a DNS server listening. This part works just fine:
matt@matt: {101} % dig www.foo.com @127.0.0.2

;; ANSWER SECTION:
www.foo.com.1D IN A 207.89.154.94
What I want to be able to do is send a dns query to the external interface of the machine on a non-standard port and have it redirect the query to a loopback address/port and return the query the appropriate query result to me.
So, after reading the man page several times, I've tried using natd like this:
natd -n fxp0 -redirect_port udp 127.0.0.2:53 192.168.7.251:55
However, doing so simply get's me a connection refused when I send it a query like this:
matt@matt: {102} % dig -p 55 @192.168.7.251 www.foo.com
; >> DiG 8.3 >> -p @192.168.7.251 www.foo.com
; (1 server found)
;; res options: init recurs defnam dnsrch
;; res_nsend to server 192.168.7.251: Connection refused
matt@matt: {103} %
I'm not exactly certain why it's failing. Is this the best approach to solving this problem? Is there a better way to go about this?

build of usbhidctl broken in -stable?
Hi,
I think the build of usbhidctl is broken in stable,
and by this I mean it is not self-contained under /usr/src
but expects to have include files under /usr/include
and the library uder /usr/lib.
If I do a make buildworld I get
=== usr.bin/usbhidctl
cc -O -pipe -c /usr/src/usr.bin/usbhidctl/usbhid.c
/usr/src/usr.bin/usbhidctl/usbhid.c:50: libusbhid.h: No such file or directory
and this is obvious because I don't have /usr/inlcude/libusbhid.h,
I still have to install it.
so I modified src/usr.bin/usbhidctl/Makefile; I added
CFLAGS+= -I${.CURDIR}/../../lib/libusbhid
but this is not enough, now the Makefile expects to have libusbhid.so
already build:
molter@cobweb[/usr/src/usr.bin/usbhidctl]$ make
cc -O -pipe -I/usr/src/usr.bin/usbhidctl/../../lib/libusbhid -o usbhidctl
usbhid.o -lusbhid
/usr/libexec/elf/ld: cannot find -lusbhid
*** Error code 1
I guess this means that src/lib/libusbhid should be built before
src/usr.bin/usbhidctl, but I don't know the Makefile magic to make
this happen.
Am I correct or is my build environment screwed up?
thanks
marco

abstracted in the email.

Right. But the same code works on other BSD systems.

Yes. And edquota (sorta, see below) works OK.

Yes.

1017, which is a valid userid.

Re: read a file from a driver
There's an example of how to do this in the ``digi'' driver. It loads it's firmware module on-the-fly (if it can) and dumps it afterwards. As you can see, this saves a bunch of runtime space (digi is the base driver, digi_* are the firmware modules): $ ls -l /boot/kernel/digi* -r-xr-xr-x 1 root wheel 36911 Mar 29 00:48 /boot/kernel/digi.ko -r-xr-xr-x 1 root wheel 17800 Mar 29 00:48 /boot/kernel/digi_CX.ko -r-xr-xr-x 1 root wheel 69548 Mar 29 00:48 /boot/kernel/digi_CX_PCI.ko -r-xr-xr-x 1 root wheel 68764 Mar 29 00:48 /boot/kernel/digi_EPCX.ko -r-xr-xr-x 1 root wheel 70336 Mar 29 00:48 /boot/kernel/digi_EPCX_PCI.ko -r-xr-xr-x 1 root wheel 11400 Mar 29 00:48 /boot/kernel/digi_Xe.ko -r-xr-xr-x 1 root wheel 72852 Mar 29 00:48 /boot/kernel/digi_Xem.ko -r-xr-xr-x 1 root wheel 73608 Mar 29 00:48 /boot/kernel/digi_Xr.ko Unfortunately, if you want to load digi from loader.conf, you have to explicitly load the firmware module(s) too as the module load function is called before the filesystem is available. FWIW, Solaris has a crude interface that will allow you to open and getc/putc a file. It's smart enough to know that it should talk to the boot prom if roodev isn't yet set. I believe it was required for Solaris' drivers to be able to read their .conf files at boot time, and was sufficient to allow access to other files in the software I was writing. generally the answer is You can't do that BUT you could make a loadable module with the firmware, and load both the module and the driver before booting from the boot blocks.. then you can unload the firmware module after booting (or whenever) On Wed, 3 Apr 2002, Kreider, Carl wrote: I am working on an embedded project running FreeBSD, and my driver for our custom card needs to load an FPGA with code.
