test10 is less than three days old... mm1 about three hours... And coming at you is love1!

http://bssteph.irtonline.org/linux/patches/2.6/2.6.0-test10/2.6.0-test10-love1/2.6.0-test10-love1.patch.bz2
http://bssteph.irtonline.org/linux/patches/2.6/2.6.0-test10/2.6.0-test10-love1/2.6.0-test10-love1_notes.txt
http://bssteph.irtonline.org/linux/patches/2.6/2.6.0-test10/2.6.0-test10-love1/love-sources-2.6.0_beta10-r1.ebuild

There's not much new in this patch aside from the obvious. There's an updated AMD power management patch (which is kind of old, but I never noticed it) and a reintroduction of a patch I should have been including but was getting under the radar. But the big changes are of course test10 and mm1.

This one is fast out the door so I could get it done before the holiday. I'll be in and out for the rest of the week.

Enjoy!

This was fast. Compiling right now... :)

What about the alsa and dvb drivers? Are they up-to-date to the cvs versions? How to find out? Wouldn't this be another area where love could be on the edge? :D

There are a lot of features that I like in 2.6 (especially in-built ALSA), but with desktop-applications I get far better performance with Gaming-Sources, therefore I'll probably not use these new sources for more than a toy :?

Still, I'm going to emerge them as I love new toys :D

I'll ask him next time I mail him, which will be later today.

I suspect it has something to do with his newly announced "class" based scheduling scheme, which will allow one to inherit scheduling schemes to suit special setups like SMT (popularly called hyperthreading), NUMA and SMP.

Having a bit of a problem with this kernel. Before I installed it, i used the gentoo-dev-sources test10 kernel, linked the new kernel to /usr/src/linux and i copied over my .config and did an oldconfig.

then i compiled it with make bzImage && make modules && make modules_install, after that i installed nvidia-kernel and nvidia-glx.

upon reboot, my xf86 refused to start.

http://pieter.dejaeghere.net:9080/XFree86.0.log
http://pieter.dejaeghere.net:9080/lovekernelconfig

My system is an Nforce2 with a gforce4ti4600.

Thanks in advance for any possible help,

Aelus

AFAIK with 2.6 (after symlinking, oldconfig, being on ~x86, using nvidia graphics) following is sufficient:

make && make modules_install && emerge nvidia-kernel

Having nforce2 & gf4ti4200 and no probles expect hd performance regression with si3112a, which I posted in lkml.

I'm getting hard lockups with this kernel when starting X... :?
It doesn't happen with test10-mm1. Thats the first love-kernel I tried, so I can't say if it is test10-specific...

Sounds like exec-shield to me - I heard that it doesn't work with -test10 because of some minor changes, it applies cleanly but has semantic errors.

I would advice you to reverse that patch and the policy change - it might mess with permission bits despite being disabled.

I'm running my own little kernel now, test10 with CFQ, runtime selectable schedulers and nick sched and it doesn't have any of the problems with X on my test machines.

Bssteph, please stop including exec-shield untill we get word from the gentoo-hardened team on their willingness to start supporting it. It's a senitive piece of code and it's pratically useless (according to Linus Torvalds), the only fix is to fix the apps, ensuring none executable stack segments merely.... disguises... overflow problems. However fixing every app on earth will never happen so it might be an acceptable solution to rely on exec-shield and PaX to provide some protection.

Ok, first time I post to a love thread: I have a problem :(
My multimedia don't work anymore; rebooting to test-9-love1, they work. That is, I get a lot of
Code:
atkbd.c: Unknown key released (translated set 2, code 0x9e on isa0060/serio0)
in dmesg (the hex code depends on the key I press). Some other multimedia codes stil work, but their code is different than before...
The keys that give an error in dmesg don't show up at all in xev/showkey...
I really don't have time to try test10 and test10-mm1 to see what it is that causes problems, and both 'cat 2.6.0-test10-love1.patch | grep atkbd.c' and 'cat patch-2.6.0-test10 | grep atkbd.c' showed that there where some changes...

This is quite annoying.. thanks for everything though!

Anyone know if gaming-sources will work with an nforce2 chipset (I'm not using onboard ethernet or onboard audio).

2.6.0-test10-love1 up and running here.
Has anyone messed with framebuffer yet? Is it working? I deactivated framebuffer since test7....

I don't see why they wouldn't.

Give it a try, but keep your old kernel lying around "just in case".

Running here to.

But the framebuffer thing is not working correctly... i think its my config, what do I need in the kernel exactly?

I have:
Code:
Support for frame buffer devices
VGA 16-color graphics support
VESA VGA graphics support

Video mode selection support
Framebuffer Console support

Bootup splash screen


this is my kernel parameters:

Code:
video=vesa:1024x768@85,ywrap,mtrr vga=0x317


But everything is just scrambled... cant read the text even though I something happening.

Another problem...

...is my multimedia keyboard.
I have a Chicony keyboard... worked great with kernel 2.4.xx, but with 2.6 some keys isn't even caught by xev.

Sure. I haven't had any problems (or else I wouldn't have released), but you know how that is. exec-shield was actually going to go on the Axe Candidate list after test10 because my tinker obsession ended with that.
Broken-outs for that provided below.

PrakashKC:
Those aren't being updated in the kernel because of the feature freeze. I believe it's best to leave that to the real kernel guys, I've got enough stuff to deal with as it is. ;)

For multimedia keyboard issues:
Try reverting this, from mm1: atkbd-24-compatibility.patch
This has been around for a bit, but I didn't realize it was breaking anything. I like my vanilla keyboard. :)

jingo:
I would remove VGA 16-color from your config... I don't think it would interfere with vesa, but I could be wrong. Vesa should be all you need. And also get rid of bootsplash until you set up an initrd. I'm 99% sure that bootsplash nicely does nothing if it doesn't have the right kernel parameters and initrd, but for safety's sake...
It's also possible that framebuffer doesn't like you yet, unfortunately. For a while vesa was a total disaster on my laptop.

Random X hangs:
Gut out exec-shield:
http://bssteph.irtonline.org/linux/patches/2.6/2.6.0-test10/2.6.0-test10-love1/broken-out/
Download the two patches, and unapply them to the tree. Unapply change_default_exec-shield_policy.patch first.

In the exec-shield-2.6.0-test8-mm1 patch the part that bumps up the EXTRAVERSION
has to be removed if I am correct :?

As I said earlier it might apply fairly clean the semantics changed so the patch needs revising.

I have been using elevator=as on in my grub.conf file. THis is the one I should be using right? How does the cfq schedular compare to this?

Thanks lovechild, removing the part that patches the Makefile in exec-shield-2.6.0-test8-mm1
made it apply cleanly.

Largely depends on the task, for a desktop I would go with CFQ.

CFQ gives you equal access to IO, which is good for a basic desktop.
