I don't know what you mean by 'removes everything emerge won't'.
I'll put it in, but can you clarify?

Make install basically copies the new kernel along with some other files to /boot and relinks vmlinuz to the new kernel. Thus, no files are deleted. (make sure you point to /boot/vmlinuz rather than bzImage)

There's a cheap digital camera around here that I don't know how to use, maybe I'll try messing with it later and see what happens.

only slight problem is when using my camera to upload pictures using mass storage usb device , I can only do it once! , if i disconnect power to camera I cannot use it anymore until reboot, get this on dmesg

I had something similar in test9-loves 1,2 and 3 when I removed my USB zip drive. Its now working in love4, though I still have to try (and fail) to mount /dev/sda before /dev/sda4 will show up and let me mount it using the fstab entry (using hotplug and a modified devfsd.conf to create sda4... it works in 2.4.22).

Its also the only love patch so far that doesn't hard-lock when i shutdown and it comes to unregister USB stuff (I suppose this must be due to the mm patches, gentoo-dev-sources works fine). To be honest I can't really tell if its faster or not, though I haven't used it much yet.

The only strange thing I'm seeing is something to do with unknown keys presumably from something to do with the keyboard. It appears in my root-tail view of /var/log/syslog after I've booted and started X (root-tail is pretty useful for that kind of thing. You get to see nasty errors as they happen so you can do something right away---like reboot to the LiveCD to recover from reiserfs corruption, which just happened not so long ago...)

<EDIT> this is what I'm on about:

Code: Select all

Nov 23 15:59:39 localhost kernel: atkbd.c: Unknown key released (translated set 2, code 0x7a on isa0060/serio0).

I get a couple of them after booting.

'make install' does whatever /sbin/installkernel tells it to do. Or, like me, you may have a ~/bin/installkernel which takes care of your personal needs.

I fixed the not-detecting-grub problem. Edit /usr/sbin/mkboot and in the function

Code: Select all

grubcheck () {
    # Right way in Gentoo to check, but grub is in system profile,
    # so rather check for lilo first....
    if [ -x /usr/bin/qpkg ] ; then
        [ "$(qpkg -nc sys-apps/grub)" = "sys-apps/grub *" ]
    else
        return 1
    fi
}

change the 'qpkg -nc ..' line so that it looks like this:

Code: Select all

grubcheck () {
    # Right way in Gentoo to check, but grub is in system profile,
    # so rather check for lilo first....
    if [ -x /usr/bin/qpkg ] ; then
        [ "$(qpkg -I -nc sys-apps/grub)" = "sys-apps/grub" ]
    else
        return 1
    fi
}

I get those too. They come after the nvidia taint and AGP messages, so I think they're related to xfree startup... dunno any more than that at this point.

Awesome @ test10, hope an mm comes soon (but not _too_ soon, I want to actually use love4 ;) )

Emerge leaves /usr/src/linux-${KERNEL-VERSION} directory. After for example emerge -C mm-sources the directory /usr/src/linux-2.6.0-test9-mm5 still exists.

That is because emerge only knows about the source files, and will only uninstall those; after you built a kernel the object files will still be in the directory, and emerge doesn't delete non-empty directories.

Just rename or copy previous ebuild over i.e

Code: Select all

cp love-sources-2.6.0_beta9-r4.ebuild love-sources-2.6.0_beta9-r2.ebuild

I'm pretty positive

Indeed.
A kludge could be to make mrproper in source trees. This would likely be ALL of the source trees (or all love source trees, whatever) unless you can get a list of what will be pruned. Doing that before you go about the pruning could do the trick, just make sure the .config is stashed in /usr/src/ or something, maybe by picking the latest config based on uname -r

About test10-mm, there is this, which I read before but didn't entirely grok:

Linus Torvalds wrote:Timing-wise Andrew is apparently going to be off for a few weeks, so regardless of whether this turns out to be rock solid or not, we'll have a few weeks of final testing before [final 2.6.0] were to happen.

Which leads me to assume we may not see a test10-mm (instead going straight to final), or it will be some time in coming.
In this light, I may release a love in a couple days based on an early bk or something (it's hard to say what I'll really do, Andrew is still posting on LKML so we'll see if we don't get lucky anyway). Just thought I'd give a heads up.

Lovechild · Post by **Lovechild** » Tue Nov 25, 2003 3:01 am

I have another request - from the highest of places, the mighty Linus Torvalds, fifth most influencial man in technology, bring of the vanilla sources.

if you have a reproducable crash, please try compiling a kernel without the preemptive option enabled as it's still prone to some cornercase errors. If you can still reproduce the crash you have a seperate bug, Robert Love is supposedly working on fixing the PKS but it's a tricky piece of code so don't expect it to be fool proof anytime soon.

In some cases disabling preemptive kernel scheduling will also fix skipping problems so it's worth a shot as a debug option.

antisthenes · Post by **antisthenes** » Tue Nov 25, 2003 3:16 am

The .config issue is taken care of because I use the '/proc/config.gz' interface anyway in the script. So would, for example, a

Code: Select all

for tree in /usr/src/linux-2.6.0-test*-love*; do cd $tree; make mrproper; done

work?

Also, I could just do a

Code: Select all

cp /usr/src/linux-2.6.0-test${1}-love${2}/.config /usr/src/

at the end (or before the mrproper step).

bssteph · Post by **bssteph** » Tue Nov 25, 2003 3:36 am

Ooh, yes, Lovechild brings up an excellent point, again kind of zipped over by me. Linus suspects preempt is turning up race conditions easier than normal. This is not to say "don't use preempt" because it's been working fine for me and plenty of others with no strange oopses. So just be mindful of that.

Yeah, the for loop is what I was thinking. I haven't given it too much thought, what I said was just pondering out loud, but that should do the trick.
It's either that or rm -rf the old trees after the prune, but I think make mrproper makes a bit more sense, and you'd have to be sure not to rm -rf what you just emerged anyway.

/proc/config.gz is probably a better idea too, I'd forgotten all about it.

For what it's worth, the new, slightly amended script is here:

http://antisthenes.dyndns.org/pub/lovebuild.sh

I don't think killing my server should be a problem, I've got thttpd w/ throttling set up.

Mainly, I've just added the cleanup part and removed the pseudo-error message.

The server gives a 403:

Code: Select all

The requested URL '/pub/lovebuild.sh' resolves to a file which is marked executable but is not a CGI file; retrieving it is forbidden.

which is cute.
I think you need to do a chmod a-x lovebuild.sh

Everyone that's been waiting on the edge of their chairs for a test10-love1 (I saw you in the test10 thread!) can breathe a sigh of relief, Andrew just released test10-mm1.

I've been toying with the idea of applying love-sources lately (I've mainly been using vanilla and mm), but I have a really quick question about bootsplash.

Does it decrease performance noticably? I remember reading in 'make menuconfig' that compiling framebuffer support can slow things down. I can live with a couple of seconds extra boot up time, but things should be OK once I boot up XFree/GNOME right? Performance is pretty important to me as I like to multitask and have several multimedia apps going simultaneously (eg ... xmms, gimp, and games

That's why I've been loving mm-sources)

Thanks! With luck, I'll be using test10-love1 when it comes out

Framebuffer and bootsplash don't cause any significant performance drop once you get into X (or at least no one's noticed one, and I think us here are all crazy desktop users). There's likely a bit more RAM being used by the kernel, but that should be it. The performance drop they're probably referring to is that text scrolling can be DOG SLOW in a framebuffer terminal (PgUp, PgDown in less takes a bit). Other than that I don't know of any performance drop.
