2.6.10-morph21 is out. Brief changelog:
- updated -as patch to -as3
- changed kexec patch to kexec3
- updated inotify patch
- made staircase optional
Now staircase has become a USE flag. kexec-tools has made its way into portage ~x86, so I'll just pull it out from morph-overlay. I've also found a kexec patch for sysvinit-2.86, I'll upload the modified 2.86 ebuild on the site soon.
teutzz: I don't know if it is possible to do what you want, but you may take a look here, it seems similar to what you want to do.
nightfrost: what xfree/xorg version are you using? AFAIK kernel 2.6 does not require to install xfree-drm, since those modules are already in.
RogerWilco: I don't know what's going on with Win4Lin  You may want to try on the software-suspend2 mailing list.

I used the x11-drm modules since I thought they might be more up-to-date. Anyway, I'm starting to think that it might have been a software-suspend issue, namely that the module fails after resuming (even though I unload and reload the module, strangely enough). I've switched to vesa driver for now and I must say that your sources are the best I've tried so far. I will try morph21 soon enough and also then try compile r128 in the kernel as well...
anyway, thanks again for great source patches  |

Glad you like it 
With kernel 2.6 it is enough to enable AGP + DRI support in the kernel to have acceleration in XFree/Xorg. I have this kind of setup on my Radeon IGP and everything works ok. You may want to compile the r128 and AGP support statically instead of modularly, it may solve your problems with suspending.

ah, i dunno what happened here. right at the very end of compile :

kernel/built-in.o(.text+0x3c40): In function `panic':
: undefined reference to `crash_kexec'
make: *** [.tmp_vmlinux1] Error 1

Great Job yardbird for this kernel patch set. One thing: what version of inotify is in this kernel? I ask because I'm about to try out beagle and on beaglewiki they said beagle-0.0.5 needs inotify patch 0.17 and beagle-cvs needs 0.18.
thanks and keep the good work up.
regards

From what I know, the version is 0.18.

The problem with kexec will be fixed in the next morph. Meanwhile here's a quick patch: | Code: | --- /home/yardbird/src-kernel/linux-2.6.10-morph21/include/linux/kexec.h 2005-02-03 20:37:02.147324123 +0100

extern struct resource crashk_res;

The problem reported by teutzz is from the inotify patch. Here's a quick fix, it compiles but I've not tested it, reports are welcome: | Code: | --- linux-2.6.10-morph21/include/linux/fsnotify.h 2005-02-03 01:44:13.665631764 +0100

+1
But enabling something without using it is not really interesting => so using kexec becomes ineluctable.

Try the simple patches above, they should take care of the issues.
Sorry about that, it's kinda hard for me to try many possible kernel configurations to spot problems like these

Don't take care about my previous message; it was just a joke. I really want to try this kexec but don't have time for that now; so this "bug" gives me an opportunity to justify time I'll spent on it ...

That's why we are there, no ?? 
You're working to make this (great) patchset (and you add specific USEflags and ebuilds for it => more work). 
Now, it's time for us to test it and report. 
Enjoy!

The sources compiled just fine, but when I try to reboot with kexec, I get a 'Kernel panic: Not sync. No init found . Try to pass init=...". Also, the fbsplash doesn't work when rebooting with kexec.

This may be because boot arguments are not passed to kexec. Are you using the /etc/init.d/kexec scripts?

Yes. I did '/etc/init.d/kexec start' and 'reboot' after that.

Did you configure properly /etc/conf.d/kexec? Mine looks like this: | Code: | # Boot partition
BOOTPART="/boot"
#BOOTMOUNT=1
# Kernel name
KNAME="vmlinuz-2.6.10-morph21"
# Root partition (should be autodetected)
#ROOTPART="/dev/hda3"
# Kernel parameters
KPARAM="`cat /proc/cmdline`"
# Initrd
#INITRD="/boot/fbsplash-emergence-1024x768" |
I have a separate /boot partition. The KPARAM="`cat /proc/cmdline`" makes kexec reboot with the same parameters of the kernel you originally booted in. Everything should work well with something like this, fbsplash is ok here too.

| Code: |
mayday@charlie ~ $ cat /etc/conf.d/kexec
# Boot partition
BOOTPART="/boot"
#BOOTMOUNT=1
# Kernel name
#KNAME="vmlinuz-2.6.9-rc2-mm1"
# Root partition (should be autodetected)
ROOTPART="/dev/hda3"
# Kernel parameters
KPARAM="`cat /proc/cmdline`"
|
And it doesn't work.Also, this is my cmdline:
| Code: |
mayday@charlie ~ $ cat /proc/cmdline
video=vesafb:ywrap,pmipal,1024x768-32@85 splash=verbose,theme:gentoo acpi=irqpoll
|
P.S. What does the "build" flag of the morph-ebuild does?
P.P.S. Why do I need to digest the ebuild after downloading it? And what does 'digest' mean?

Do you not need to pass a root=/dev/your_root_partition option to be able to boot?
I think you should make sure that the rootpartition in /etc/conf.d/kexec matches your real root partition.
yardbird: Do you have a broken-out for morph-sources?
Where did you get the kexec patch from? |

Yes, you were very right; hda3 was my boot partition 
But fbsplash still doesn't work and if I try to pass the Initrd option to kexec I get this error:
| Code: | charlie mayday # /etc/init.d/kexec start
* Loading kernel vmlinuz-2.6.10-morph21 for Kexec... ...
Cannot open `"$INITRD"': No such file or directory |
Added INITRD in /etc/conf.d/kexec
| Code: | charlie mayday # cat /etc/conf.d/kexec
BOOTPART="/boot"
BOOTMOUNT=1
KNAME="vmlinuz-2.6.10-morph21"
ROOTPART="/dev/hda6"

I'll post a link to a broken-out directory tomorrow.
The place where I got the patches is:
http://www.xmission.com/~ebiederm/files/kexec/
I used the tarball named 2.6.10-mm2-kexec3.tgz, dropping out the crashdump patches and doing a (rather simple) backport of the other patches to plain 2.6.10. There's a small patch-fix some posts above to allow kernel compiling also when kexec is _not_ enabled.
You other choice is to get the broken-out tarball of latest -mm kernel and pick up just the kexec patches. But it is more difficult to backport to vanilla 2.6.10 and possibly it is less stable too.
Hope that helps

Great work on morph21, like usual. I must say I love the use flag for the staircase scheduler. Performance is so much better without it. cfq-ts seems to work pretty good though.

Ok, thanks for the report. The inotify patch seems to be a bit flaky this time (fortunately there's an updated one available which will go into morph22).
