[gentoo-user] kernel 2.6 upgrade howto

[gentoo-user] kernel 2.6 upgrade howto

[Maarten]

Hi list,

I'm new to the list (and gentoo) but not to linux.

I just started with gentoo, had to use the 2004.2 image since 2004.3 crashed 
at installtime on my machine (thinkpad 600X)...  
I used stage 2. Since then I succesfully installed a lot of apps like KDE and 
such, but my kernel is still a selfmade 2.4 one.  Now I need to get my 
wireless cards working but I'd rather upgrade the kernel first for fear of 
doing things twice (or wrong) due to the changed pcmcia drivers.

I think I correctly upgraded 2004.2 to 2004.3 but how do I check that to make 
sure?  The machine did not do anything spectacular when I made that change, 
is that expected behaviour ?  Now for the fullfillment of the transition to 
2004.3 I need a kernel 2.6, right ?  Can someone point me to the docs that 
detail that step cause I could not find that very well. 
Or do I just somehow get the sources and start compiling ?  
How do I make sure I retain my current kernel as a second boot option if the 
2.6 kernel will not boot ?

Thanks in advance,

Maarten

Okay let's divide the questions shall we. There isn't really any
revision to gentoo. I think you have switched your profile am I right
? What you have is basically told the system with system package were
recommended and current. This isn't the right answer but is the simple
answer. The date tags are primarily used for the releng team and grp
packages. Profiles are an another thing on it's own but it tells the
system defaults in a nutshell.

>  The machine did not do anything spectacular when I made that change,

If you were up to date with your local portage tree and recently
update your installation there is no reason to anything since you
already up to date. You only switched profile from what I can read.

>  Now for the fullfillment of the transition to 2004.3 I need a kernel 2.6, right ?
Not really, AFAIK gentoo hasn't switched to 2.6 by default. If you
still need to you can run a 2.4 kernel without any problems except you
will miss some goodies. But, if you aren't confortable with 2.6 or
even a linux kernel you might want to stick with a 2.4 kernel. It just
works.

Sure here ya go. It still has that fresh smell from the oven (It has
been updated recently)

http://www.gentoo.org/doc/en/migration-to-2.6.xml

May I suggest you go to www.gentoo.org and look at the left side of
the navbar to see a big category called Documentation. Check out the
user docs section it's pretty good.

> Or do I just somehow get the sources and start compiling ?

To keep up to date a gentoo installation :

emerge sync 
emerge -uDav world

What it does is emerge sync update your local portage tree to have the
latest ebuilds and then you ask portage to check every package on the
system to see if there is something to update and ask you first if
everything okay. Might want to read the man pages of emerge.

> How do I make sure I retain my current kernel as a second boot option if the

What boot loader are you using ? Lilo or grub ? Here's my grub.conf
that you might find useful :

default 1
timeout 5
splashimage=(hd0,0)/grub/ninja-girl.xpm.gz

title=Working Kernel
root (hd0,0)
kernel (hd0,0)/vmlinuz.working root=/dev/hda4 video=vesafb:ywrap,mtrr vga=0x317
initrd (hd0,0)/initrd-1024x768

title=Test Kernel
root (hd0,0)
kernel (hd0,0)/vmlinuz root=/dev/hda4 video=vesafb:ywrap,mtrr vga=0x317
initrd (hd0,0)/initrd-1024x768

title=Old Test Kernel
root (hd0,0)
kernel (hd0,0)/vmlinuz.old root=/dev/hda4 vga=0x317 video=vesafb:ywrap,mtrr
initrd (hd0,0)/initrd-1024x768


Hopes this will help you out

If that is what I think it is, yes. [Changing some symlink somewhere I forgot]

indeed.  So the kernel is not updated with changing profiles ?
(or at least, not when going from 2004.2 to 2004.3)

I run linux kernels since 1996, so I should be "comfortable" with them. ;-)
I (wrongly) assumed gentoo-latest-rev used a 2.6 kernel so I was unsure how to 
transistion to 2004.3.  So, that is cleared up now.  
However, I will still want to run with 2.6, definitely.

Of course I did.  In fact I couldn't have installed gentoo without it. :-)
(Those are real fine docs by the way. Kudos!)
Somehow I overlooked that migration document. I guess it's just all too new 
and confusing and overwhelming the first few visits...  My bad.  Thanks!

Grub.conf will work.  My question was rather, will one kernel not overwrite 
another (as is sadly the case with a lot of other linux distributions).

One last question:  Do you need to re-run grub-install after changing this 
file or is it 'okay to go'.  (you'll note I come from the lilo world ;-)

Yes, I think it did.  Thanks again.

If so yes you changed the profile.

No you have to emerge a different sources like gentoo-dev-sources
instead of gentoo-sources.

If that's the case i'll go less easy on you ^_^ (just joking) . You
might find this page useful :

http://packages.gentoo.org/packages/?category=sys-kernel

You should be able to pick a kernel that fits your needs. I would
suggest using gentoo-dev-sources at first if you just want a 2.6
kernel that works.

There is a resume at the end of the page (
http://www.gentoo.org/doc/en/index.xml#doc_chap7 ) But hey it's monday
for everybody !  The gentoo devs are working on rebuilding the web
site to be more accessible. The main design has been approved a while
ago so I hope this year we'll be able to enjoy the face lift.

That depends on how do you compile your kernel really. I do it this way :

make && make modules_install install

It will build a 2.6.x kernel, install the relevant modules it just
build and copy the bzimage at the root of /boot as vmlinuz (the
.config and System-map is also copied by padding the revision number
at the end). If it already find vmlinuz it will rename the old kernel
as kernel.old ( the old config and System-map too). What I do when I
like a kernel is to copy the working vmlinuz to vmlinuz.working with
it's config and System-map and append .working. That way it's never
clobbered when I don't want too. It's the solution for the lazy people
like me. Here's a snapshot of my /boot since I'm probably not coherent
enough :

ls -l /boot

Nope grub doesn't need to be reinstalled. It scans it's configs on the
fly so you only need to edit grub.conf and that's it. Oh and welcome
to the light side lol.

OK. done that, but first the 'emerge world' proved to be quite a bit longer 
than I expected as it included X and mozilla amongst others. 
I believe my poor old pentium3 500 is still pounding on it, hehe.
So things take way longer than expected (no hurry though).
Does this like happen every other week, having one or the other 'major' 
ebuilds renewed ? I mean of the size of X, or Kde, or OOo, glibc and alike ?
I'm beginning to believe my pentium3 is severely underpowered here... ;)

What is your opinion on the udev vs ... choice ?
Which is best when handling lots of hotpluggable devices (usb-storage etc) or 
is there no real difference there ?  What happens if I need to boot a 2.4 
kernel, will the missing and/or incompatible /dev structure not bite me ?

8-)  
Go right ahead.  I should be quite fluent in linux now, just the gentoo part 
is new. But I've used old slackware, redhat, suse & debian (in that order)
So feel free to skip the basics. The USE flags and some of the paths of config 
structures daunt me for now but that's basically it. And I want to learn 
gentoo the *right* way, not the easy-but-you-will-regret-that-later way.

Yeah, I chose that one.

No, no, you make perfect sense. I get it.  I'm already happy that the install 
script does not munge the bootloader config file (as some do IIRC)

Lol indeed; I fully agree.  Lilo caused me no end of trouble, and quite 
recently even cost me over 2 days work with 480 GB raid5 data at stake, more 
or less.  Well, long story, I'll not bore you with it but suffice to say that 
some new SATA boards' drive mapping will wreak havoc on how lilo will see 
drives (let alone BOOT from any of them). I've seen more L99 99 99 99 and L00 
00 00 00 errors than I really care to remember.  Lilo is dead for me now. 
I'll never touch it again. (Well, after the legacy systems have gone...)

Hey, I already like this list, feels right at home  :-)) 
Thanks for the welcome!

Now to get 2.6 + kismet + gpsd running and I'm truely happy.
All the rest seems to work fine already.

udev, without a doubt. Working with several hot-pluggable devices and
devfs or a static dev is a nightmare, because the name allocated to each
device depends on the order in which they were connected/detected. udev
lets you symlink these names to human-friendly names like /dev/camera,
/dev/mp3player etc.

See http://www.reactivated.net/udevrules.php for a good explanation of
how to do this.

That depends on how often you update. If you do it once a week
probably not. But i'm one of those stupid people who like to update
once per day. Altough my servers don't see a lot of compile time on
stable and at most once per week.

> What is your opinion on the udev vs ... choice ?
Personnally udev is the way to go, most of the troubles of the early
days are gone if not all. Never had any troubles with and as a bonus
you can reserve some blocks to some device like if you like your usb
key to always be /dev/sda. It's pretty flexible, useful, it's not
deprecated and it's maintained.

> Which is best when handling lots of hotpluggable devices (usb-storage etc) or

Hotplug + coldplug (hotplugging at boot)

>  What happens if I need to boot a 2.4

Well, now that modules-init-tools support both kernel series there's
only one thing stopping you : devfsd vs udev :). But there's hope !

Don't know what are the settings available on the stable baselayout
but here's an interesting snippet of my /etc/conf.d/rc :

# Use this variable to control the /dev management behavior.
#  auto   - let the scripts figure out what's best at boot
#  devfs  - use devfs (requires sys-fs/devfsd)
#  udev   - use udev (requires sys-fs/udev)
#  static - let the user manage static nodes

RC_DEVICES="auto"

So in a resume you can run a 2.4 kernel with devfsd and it will be
detected and used. Since udev is a userland program, a 2.4 kernel will
not be bothered with it. That's in theory, I don't know if devfsd and
udev will block each other in portage. If not well run devfsd only
until you switch completly to 2.6.

That's the spirit ! Browse the documentation & tips and trick section
of the forum. It's so juicy with goodies it's unbelievable. Anyway
will all of the doc available, it's pretty to figure it out ;).

Thanks for explaining that.  Thanks Neil, too.  It was always awkward, the 
shifting devicenames under 2.4.  So this solves that.  Great!

That was suse actually, a distro which I really like(d?) but one has got to 
move on. The thing with suse and redhat is, once you _need_ to compile 
something because there is no binary for it, then the trouble really starts.
Good luck getting a promisc-cabable driver for a wifi card into suse without 
hours and hours trial and error.  Well, sometimes you're lucky.

I'm almost ready to reboot to 2.6.9 but a little (but potential showstopper-) 
problem showed up.  I have two wired NICs, both of them 3Com575TX. (not a 
typo, it is a different card than the 3C574 or 3C589 cards) (Cardbus, 100TX)
I know that I need(ed) the 3c575_cb module for it under 2.4.  The thing is, 
that came with pcmcia-cs, not with the kernel. This new kernel has the pcmcia 
built-in but it seems this driver was deprecated; it just isn't there.
Now chances are it is merged into something else, but not knowing gives me the 
creeps. No network -> no nothing. No emerge that is. No emerge no fixing. 
And I have no other brand laying around (except for wireless but that's not 
proven to work yet)
Anyone know what happened to this infamous 3C575 driver ?
A grep for 575 in Documentation/* (including Changes) yields nothing at all. 
The same in .config by the way.

The card is great otherwise, never any problems with it

Did you try out the 3com-drivers in the PCI section? Most PCI drivers work for their correspondent Cardbus Card. Try to insmod them manually if they aren't loaded right from the start. You could then change the settings in /etc/pcmcia to make them recognized. I had the same issue with 8139too drivers.

Never mind that.  I've found the explanation, so the solution can't be far 
off.  It seems all cardbus is hence handled by the PCI driver / bus, thus the 
3C59x driver.  I suppose however that I need to reconfigure the kernel for 
PCI hotplug support so that'll be for tomorrow... 
...gotta catch up some sleep now.

It is misleading to refer to gentoo 'versions'. 2004.2 and 2003.3 are just 
releases of the install cd.  After installing, and running "emerge -u system" 
your system will be up to date with the most recent stable versions, 
regardless of which install cd you choose.

PS you can run any kernel you want...2.4 or 2.6

good to go - you just need to edit grub.conf and thats it

gentoo slots all kernel versions so all you need to do is update the
/usr/src/linux symlink to the newly installed kernel version.

dont forget that gentoo runs with /boot partition unmounted so
you will  need to mount it before you copy the new bzImage over

If you are changing to 2.6 then there is the udev versus devfs choice 
to make, I would choose devfs in the 2.6 setup until your happy then  think
about udev after that.

Re: [gentoo-user] kernel 2.6 upgrade howto

[brettholcomb]

1.  Merge one of the 2.6 kernels - I used gentoo-dev-sources.  
2.  Change the /usr/src/linux symlink to point to the /usr/src/2.6directory
3.  Cd /usr/src/linux and do a make menuconfig
4.  Go through the menu and select the options you want.  I don't recommend taking the 2.4 .config and running make oldconfig on it.
5.  Exit menuconfig (save!)
6.  Run make && make modules_install
7.  Copy the bzImage to /boot - mount /boot first if it's not already.
8.  Set LILO or Grub up so that you have another kernel entry it can boot - I call mine Test.

As for udev I went from 2.4 to 2.6 and just went with udev.  Check the Gentoo docs for some docs on links to other docs on moving to udev.

At least with grub it work fine it copyies all useful files (config, 
System.map, vmlinuz) do the backup of  files already there easy.

The Gentoo docs say for 2.6 simply do make && make modules_install.  I 
think I tried the make install and got an warning message.

Whatever works <G>.  I prefer to mount my boot and copy bzImage by hand as 
I give them new names.  If you're doing that many machines I'd let it copy 
it to!<G>.

in a 2.6 kernel, typing make help gives this information:

"install       - Install kernel using
                   (your) ~/bin/installkernel or
                   (distribution) /sbin/installkernel or
                   install to $(INSTALL_PATH) and run lilo"

/sbin/installkernel is from the debianutils package, so not
surprisinglly it installs the kernel as debian would expect to find it.
man installkernel or head /sbin/installkernel for more info. 

This seems to install the kernel as /boot/vmlinuz-version with a link to
that from /boot/vmlinuz, and the old kernel moved to /boot/vmlinuz.old. 

Is that what you see when you run make install Bastian?

The only warning message I've seen is one saying that
grub.conf may need to be edited, it doesn't.

If you trust the makefile to install the modules, why not the kernel
too? It's a lot easier than manually renaming three files (kernel,
System.map and config), renaming the three symlinks to them, copying
three files and creating three new symlinks.

Well, I don't have to do that much work to install my new kernel.  I just 
copy 3 files over and edit grub.conf.  All my 
config/System.map/kernel/initrd files have suitable extensions, so there's 
never any replacement.

For the few systems I have I just prefer to do it manually.  I copy them over to a new name them like vmlinuz-2.6.9-r1, etc.  I also copy the working kernel to something like vmlinuz-prevgood.  Then I update the test section in LILO to point to the new kernel and it's available for the next time I decide to reboot and try it.

That's exactly what make install does.

Once again, make install links the previous working kernel to
vmlinuz.old. Still, if you prefer to do the leg work when you have a
willing but dumb slave ready to do it for you, that's your choice :)
