[parisc-linux] Newbie on PA: Trying to compile kernel

[Markus Döhr]

I just installed 0.9.2 on a 712/60 and I'm happy linux'ing ;-)

However, when trying to compile a cvs checked-out kernel I'm always getting
ramdisk.bin not found. I searched the archives, found some notes on where to
find one but on the site specified there are no.

Here's my disk setup:

sda1  Boot   Primary   Linux/PA-RISC boot       24.68
sda2         Primary   Linux ext2             4096.19
sda3         Primary   Linux swap              172.74

I'm not sure if I even need one.

hppaubi:~# cat /etc/palo.conf
# obsolete with palo-0.94 # --bootloader=/boot/iplboot
--commandline=2/boot/vmlinux-2.4.0 root=/dev/sda2 HOME=/
--recoverykernel=/boot/vmlinux-2.4.0
--init-partitioned=/dev/sda

Can anyone please point me to the right direction?

Thanx a lot!

Good to hear that! I hope you enjoy :)

First of all, a reminder about the CVS. You have all the infos about it
at 
 http://www.parisc-linux.org/tools/index.html#anoncvs

After, for the cross-compiling, you need to download the xc here
ftp://puffin.external.hp.com/pub/parisc/binaries/LinuxX86/xc-latest.tgz

You untar the archive from the / and add the path in your $PATH
Something like that:
export PATH=/opt/palinux/bin:$PATH #for bash, of course

then you go in linux directory, you do make menuconfig with the good
choice.

then make dep vmlinux and you upload your kernel on the 712 via ftp.

Till you are not sure of your compiling talents, the good idea is to
copy the vmlinux file in /boot with a name
slightly different of the old one. like that you have in /boot
vmlinux-2.4.0 and vmlinux.2.4.0-new, for example.

At the boot time, you press escape to enter in BOOT_ADMIN and type boot
pri ipl and you modify the 0 entry to point
the good file! That's all.

If you want to know more, try

Good luck, Thomas.

Thanx for you quick answer!

I have :-)

No, I'd like to do a native linux-kernel-on-linux compile.

I'm compiling kernels since 1.9.X (don't remember exactly) on INTEL and
Sparc, but never did on parisc. So I did the following:

hppaubi:/usr/src# export CVSROOT=`cat linux/CVS/Root `

hppaubi:/usr/src# echo $CVSROOT
:pserver:anonymous@puffin.external.hp.com:/home/cvs/parisc

hppaubi:/usr/src# cvs -z5 co linux palo

The documents tell me to use either NFS or a RAMDISK in palo/Makefile and
_here's_ the problem (or the documents are outdated). I'll try the manual
approach and see what'll happen.


PS-OT: I wonder if SAP will port their application server to parisc/Linux...

Hi again,

Damn it, I did well but it was the stuff for you. I am sure it will help
some one else :-)

I hope you have time. Compiling with 712 is fun but long :(

These documents were written at a time when HDD were not so well
supported.
If you just want to update your kernel, you just do 
apt-get update
apt-get upgrade # in order to get the last gcc version

after that, you follow what I said about make menuconfig...

I tested this way of producing kernel a long time ago. I am sure it will
be ok.

FYI, the ramdisk or NFSroot is needed if you do a make palo but you do
only make vmlinux!

I really do not know. Perhaps, Helge Deller will know :)

Good Luck anyway, Thomas.

I would imagine, only until there is a real market demand for palinux, and if large distros
such as SuSE adopt palinux.  ... and of course when palinux becomes stable.

Hi Markus, Thomas and Randall,

That's funny. Right yesterday I got a B180L for my desk and a B2000 in one of the 
server-rooms. Believe me, I'll try to build the R/3 kernel for PA/Linux, but 
this is primarily my private interest and is not related to my job or my daily tasks here.

I asked already at a higher level how SAP's interest for SAP on PA/Linux is.
But as Randall said, SAP wouldn't even think of it, if not one of the big vendors
(SuSE, RedHat, anyone else or even HP itself) would take over customer-support 
for R/3 on PA/Linux.
Furthermore I personally also don't think that SAP on PA/Linux will ever 
happen, mainly because
a) AFAIK HP will or has already stopped their PARISC product line - which is a 
knock-out argument against too much further development on that platform, and
b) SAP will only support one Unix-Platform per processor-architecture. This
would mean that HP would have to drop R/3 on HP/UX - in favour of  R/3 on PA/Linux -
which I think would never happen.

Greetings,
Helge
