[parisc-linux] 2.4.6-pa20 question about modules

[Joël Soete]

Hi Thomas,

With your tips
(http://lists.parisc-linux.org/pipermail/parisc-linux/2001-July/013081.html)

the cvs 20010717 seems to works fine.
(for b180 still have to unplug re-plug kdb)

I also try to recompile it with the .config file supply with palinux-0.9.2.
It also seems to works well but modules are not install naturally.
Can you explain me how to compile it and install it?

Thanks in advance for help,
     Joel

PS: How is it possible to cvs co a previous kernel release now (f.e.
2.4.0-pa30)?

Nice to know that. But, I think I will deliver a big patch for the
keyboard story. Then, I will need some testers. Thanks to be one of them
:)

First, you must know that some of the drivers are not modularized yet. I
think that it looks like pc modules. But since I am not a guru in this
stuff, I think someone else will tell you

I would like to know. I think, if you read at Paul Bame litterature, he
said that it is broken for 2.4.0.
I can grab old versions with cvs co -r 1.83 linux, for example.
To know the release you want, use this:

Thanks again for reporting, Thomas.

PS: I also hope an explanation of modules on hppa. I will have to write
all the cleanup stuff for the mouse.

If I understand correctly, you are rebuilding the kernel, and want
kernel modules installed correctly under /lib/modules?


cd /usr/src/linux   (or wherever your source tree is)
# save your .config file, if you want it
make distclean
cp <config file> .config
make oldconfig
make dep
make
make modules
make modules_install
cp vmlinux /boot/vmlinux   (or whereever you want it to go)

Hi Richard,

Just to clarify:
does it means that I have to (or I can) recompile my kernel from my
palinux-box?

Is it not possible from i386 linux box and the cross compiler?

Thanks again for support,
     Joel

Re: [parisc-linux] 2.4.6-pa20 question about modules

[Joël Soete]

Richard,

Just a small tips I use on my i386 linux-box: I launch the make in one line
and tacke a log which I can so analyze later like:

make dep clean bzImage modules modules_install 2>&1 | tee
/var/tmp/kl-200107.log

(presently replace bzImage by vmlinux for parisc on a parisc-box seems to
work)

May be, it should be helpfull :))

Joel

ps: but with parisc-box I met a problem which I do not met with the
xcompiler on i386 linux-box:

dmfe.c: In function `dmfe_timer':
dmfe.c:1193: Unable to find a register to spill in class `FP_REGS'.

any idea?

don't do this.  make dep creates dependencies which then need to be taken
into account for later steps.  you might rely on make getting this right,
but i don't.

bug in that driver (it has x * 1.5, which uses fp).  fixed in alan's tree,
though i don't believe it's made its way into linus' tree yet.

consider youself lucky you get compile-time errors instead of random
inexplicable fp corruption.

Safer to run them separately.  You can still easily log them, there are
many possible ways to do this ...

$ for target in clean dep vmlinuz modules modules_install
> do make $target 2>&1 | tee -a /var/tmp/kl-200107.log
> done

$ (make clean ; make dep ; make vmlinux ; make modules ; make modules_install) 2>&1 | tee -a /var/tmp/kl-200107.log

$ script /var/tmp/kl-200107.log
Script started, output file is /var/tmp/kl-200107.log
$ make clean ; make dep ; make vmlinux ; make modules ; make modules_install ; exit
...
Script done, output file is /var/tmp/kl-200107.log
$
