RE: [expert] SMP newbie
It has to do with how many threads the program is able to start. If the program can work with multiple threads in parallel then it will use both CPU's. However, that is generally a function of the scheduler in the kernel to decide where each process (or thread) will run and when. So I would think that compressing would be hard to parallelize. On the other hand you can probably compress and write an image to the CDR at the same time without much problems. Or maybe even runt setiathome and not cause trouble. -Original Message- From: Steve Philp [mailto:[EMAIL PROTECTED]] Sent: Friday, September 17, 1999 12:00 AM To: [EMAIL PROTECTED] Subject: [expert] SMP newbie Hello all!

Hi there!
I just wondered (again):
If you define aliases in /etc/conf.modules how does the system know which

An example:
If I load

it works. What if I'd type
alias my_yummy_scsi_card [module-name]
?
Valid kernel-parameters are described in kernel-parameters.txt, but what
about valid module-aliases?
Obviously I am missing something. May anyone help me?
[...]
Hi Tom,
in the special case of "alias scsi_hostadapter [module-name]"
this entry is only needed by the shell script "/sbin/mkinitrd"
line 158-165:
--88--
if [ -f /etc/conf.modules ]; then
scsimodules=`grep scsi_hostadapter /etc/conf.modules | grep -v '^[
]*#' | sort -u | awk '{ print $3 }'`
for n in $scsimodules; do
# for now allow scsi modules to come from anywhere. There are some
# RAID controllers with drivers in block/
findmodule "" $n
done
fi
--8-8--
If you change the entry in /etc/conf.modules
alias scsi_hostadapter [module-name]
to
alias my_yummy_scsi_card [module-name]
your initial ramdisk will not contain the module for
your SCSI hostadapter and your machine will not boot
if you are booting from a SCSI drive and have your
SCSI host adapter support not built in the kernel.
Hi Harald,
thanks a lot for your explaination but I still don't understand ;-).
I see the case with mkinitrd, but what if I don't need any SCSI devices on
startup and the card driver is built as a module?
If there is now a request *at runtime* (let's say to a SCSI CD burner)
modprobe looks into /etc/conf.modules and sees the line
alias scsi_hostadapter [module-name]
How does it know that the string 'scsi_hostadapter' refers to a SCSI host
adapter?
Or did I got the wrong way round and modprobe doesn't need to look up
conf.modules since the card has been detected during boot? Does modprobe
query /proc/scsi first? Does your explaination mean that I don't need this
entry at all if I don't need SCSI during init?
Sorry if I seem to look exceptionally dim but I really want to understand
this correctly.
I really hope you take the time to enlighten me about it.
[...]
Hi Tom,
to be honest I didn't think of this case in my previous mail
at all and I don't understand it completely too.
Obviously my statement that the entry
alias scsi_hostadapter [module-name]
is only needed by /sbin/mkinitrd is wrong.
I have looked at the kernel sources and found this in line
3220-3224 of /usr/src/linux/drivers/scsi/scsi.c
(kernel-2.2.29-27mdk)
#ifdef CONFIG_KMOD
if (scsi_hosts == NULL)
request_module("scsi_hostadapter");
#endif
So I think if the kernel detects that it needs
a driver for a SCSI hostadapter and no one is loaded
it requests kmod to load a module "scsi_hostadapter".
Then kmod looks up /etc/conf.modules for a line
alias scsi_hostadapter [module]
and if this line exits kmod loads [module].
If you want to know this precisely you should ask
Bjørn Ekwall [EMAIL PROTECTED] who is the expert
for this.
