Re: EIDE Problems - fsbn read error

It seems that it sits there trying to recover from this "soft error" but never does, and never maps it in the replacement block table as "bad". Is there a way to "reformat" the drive (low level, perhaps) so that it maps out the appropriate replacement table for the darn fsbn? Or how about a way of adding bad blocks to it? Any help in solving this would be appreciated !! Upgrade to 4.0 or better yet 4.1, the new ATA drivers there has better error recovery... Oh, and there is no idea in reformatting a modern ATA/IDE drive, if they have bad sectors they have used up all their spares, and should be retired asap... -Søren To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

FreeBSD belly up with big config
With 1800 interfaces in the system Freebsd seems to use about 50Mhz of cpu when idle in "interrupts" even when there are no interrupts to process. on a 500Mhz box it uses 10% of the cpu and it seems linear with different speed processors. the 1800 interfaces are 900 DLCIs on a T3 frame with 900 bridge groups (rather common for a DSL delivered via Frame). This with just one line...the same problem could occur with say 8 T1 lines with 100+ DLCIs on each. It seems that there is substantial overhead just scanning interfaces for some routine maintenance...is there any hope of alleviating this deboggle?

Re: How to make *real* random bits.
Thus spake Poul-Henning Kamp ([EMAIL PROTECTED]): between events. Because of this your T3 value can be considered the T1 value for the next random bit you generate. No it cannot. If you did that then the probability would skew from bit to bit. If the (t3-t2) was large bit N == 1 and the probability of bit N+1 == 0 is .5 then. Yes, but you can use the 3rd bit as bit 1 for the next step. With 15 events, that gives 7 bits/second: bit 1: 3 1 (is event 3 of the last bit) bit 2: 2 1st bit 3: 3 1 bit 4: 2 2nd bit 5: 3 1 bit 6: 2 3rd bit 7: 3 1 bit 8: 2 4th bit 9: 3 1 bit 10: 2 5th bit 11: 3 1 bit 12: 2 6th bit 13: 3 1 bit 14: 2 7th bit 15: 3 1 (is event 1 for the next bit) Alex -- cat: /home/alex/.sig: No such file or directory To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

Problem linking/integrating Socket stuff into my driver code
Hi everyone,
I wrote pseudo-device driver for FreeBSD kernel. It safely comes up at boot
time. There is also a corresponding device node "/dev/mydevice" for my code,
so that whenever someone makes an:
fd = open("/dev/mydevice", .. );
ioctl( fd, COMMAND );
the "mydevioctl()" function within my code will take care of the COMMAND
requested.
* NOW , My problem is !! **
I tried to add some networking functionality to my driver. Although I
#include'd every required socket and net related header in my code
sys/socket.h, netdb.h, netinet/in.h and etc. I get the errors
"Undefined reference to socket()" , same for connect(), gethostbyname(),
accept() etc. In my previous life B.K. ( Before Kernel ) I used to link to
socket related libraries ( -lsocket, -lnls ), but this is not a standalone
program and I am not supposed to make explicit linking to any library. This
is KERNEL anyway, it has object code for almost every standard function you
may want to use (e.g.socket() ..) For example: kern/uipc_syscalls.o has the
socket() definition and uipc_syscalls.o is already in the list of object
files to be used in kernel make; all being compiled together.
After including the required header files and after ensuring with ( nm -s
uipc_syscalls.o ) that socket() is defined there, how do I get my code to
see these functions.
Some Bullets that might help

* FUNNY:: I wrote a small client/server chat program (for testing) ;compiled
both client and server code using "cc -o server server.c", "cc -o client
client.c" and DID NOT LINK any special library... IT WORKED ??!! I put
server code on another PC over network and they get to communicate with the
client. "cc" somehow knows where to link I guess (Is there a list of the
libraries that cc links somewhere? or does it just look under /usr/lib)..
And the second funny thing is that, when I do a symbol lookup " nm -s
client" on the client program the functions that I use , socket(),
gethostbyname() still look U ( Unresolved, Undefined ?)
* Kernel Makefile first compile everything with "cc -c " , i.e. "don't link
at this time" option * After everything is compiled, kernel links them
together using linker ld
* cc without any option does all the compiling and linking job, but I am
bound to use the KERNEL's rules "cc -c" first then link everything together.
* Other drivers in the kernel ( e.g. aha SCSI driver) don't have any compile
and linking problem and usually none of them need a special treatment for
linking. Check /usr/src/sys/compile/GENERIC - Makefile . NORMAL_C type of
compilation is enough for them.
