I'll have to give it a try, will it actually break any of the iptables functionality?

I don't think it breaks any iptalbes functionality, as shorewall works fine so far and packets are marked by command name.
It's more a problem with dependencies caused by the command-match configuration and it's not an issue with the iptables code itself.

I'm wondering a little on how to get the best performance out of nitro.

I'm coming from archck fed up with slowness. I'm not really sure if it will help or not. But I was using Reiser4 w/ anticipatory and no preempt. Even with SCHED_BATCH'd portage stuff, when portage stuff ran, the whole system was really slow, especially with big apps like QT4.

Just some general specs:

Abit NF7-S
AMD Athlon XP 2000+ @ 2.14GHz
256MB PC2100 RAM @ >333MHz
Nvidia Geforce2 MX 400 w/ 64MB SDRAM @ 235/195
Maxtor 30GB 7200RPM 2MB Cache HDD

Software side:

~x86
Reiser4 1.0.5
GCC 4.0.2 / Binutils 2.16.1-r1 / Glibc 2.3.6-r3 w/ omitfp and nptlonly
Xorg7
KDE 3.5.1

CFLAGS (now) are CFLAGS="-march=athlon-xp -Os -fno-ident -fomit-frame-pointer -pipe", used to use CFLAGS="-O2 -march=athlon-xp -fno-ident -fomit-frame-pointer -pipe" but I heard Athlon XPs worked better with -Os because of smaller cache as compared to P4s, and so I switched to that in both make.conf and my kernel config.

As you can probably tell I have a need to push my system to the limit and to use the latest and greatest software. But anyway, I'm hoping with this info someone could help me get the most out of nitro. Because having old hardware that feels like old hardware just isn't any fun... I'm probably going to try some experimental stuff like GCC 4.1 and stuff because I use Azureus and it'd probably help me out to have it native with GCJ.

EDIT: One thing I'm noticing that I haven't before is that when I click on different links in Konqueror it starts using a lot more CPU (as high as 15% or so) and seems less responsive than it was on my last kernel. What could this be?

The iptables problem is due to my flawed config. just remove the select lines for now. although
the depends are not all there if you do it, it should work well if you select iptables and then owner match support before command and pid/sid mathing.
I'll revert back to the normal behaviour as most people already figured the Xtables issue (the select lines were __SUPPOSED__ to make the transition more flawless, but i think i messed up a little

)

cheers,

T

PS: lancelott: just use the nitro-optimized setting for slice values. The KDE hang seems to be KDE related, as lags don't seem to appear on other WMs.

PS: sorry that i don't support for now, but i'm at rebuilding my system
so it might last a little until i get out of the console-land...

lancelot: A kernel can only do so much for you. Your problem is ram. More ram will do you more good than any kernel modifications.

It is worth noting, however, that SCHED_BATCH is different in the 2.6.16-rc -ck based patchsets. You need new schedtools (v1.2.6) and use the new SCHED_IDLEPRIO instead.

Even with idleprio things aren't much better. In fact, it's about the same.

This kernel isn't stable at all. I thought it was originally due to -Os, but I tried -O2 and both still caused Konqueror to crash twice. After the crash, it is impossible to start Konqueror again. Even more than this... If I do alt-F2 and start Firefox, the run command thing freezes up and after I terminate that I'm left with a black background as my desktop.

Is this a config issue or is the kernel itself just...crashy? I might try your 2.6.15-based kernel to see if that's any better. This is just not much fun.

I have problems to get fbsplash working with this kernel. When the kernel is loaded the splash is not loaded. It only loads with the init script very late in the boot process. I can't give a lot of information because I have no information. There aren't any error messages. Should there be something related to the splash in dmesg? I can't find anything in my dmesg. I used a lot of different kernel options but nothing works.

This is my grub entry:

I just discovered another problem with iptalbes command matching. I want to mark packets of azureus for later traffic shaping, so i matched the java command and assigned a mark for that. But almost always when I close azureus, my system totally freezes. Took me a long time to find out, that command matching is the reason for that, as no logging output has been created. Perhaps azureus closes right in the middle of the matching-function and the kernel reads data that no longer exists. But that just a thought...

However, in case someone else has similar problems, here's my workaround:
add yourself to the p2p group and use group-matching instead of command matching. Then start azureus -or whatever you need- by invoking

hi...
just tried out the latest sources and since i recently had a gcc upgrade so decided to re-compile the ati-drivers so that thery are under the same gcc (4.1.0-pre20060223), but the package fails to compile and giving me this error message

ok i took metalshark's advice and upgraded to xorg-7 and used some cflags from his make.conf and ati-drivers now compiles fine against the 2.6.16-nitro...i still don't know what solved the compiling problem but i will find out and post the specific flags here...(huge thanks to metalshark

)

Although the drivers compiled successfully i still cannot startx...when using the fglrx or the kernel radeon drivers it says "No matching Device Section for instance (BusID PCI:1:0:1) found" besides that it fails to load the dri and drm modules...claiming that they do not exist, but i think this could very well be some mistake on my xorg.conf...as i'm not too familiar about the xorg-7's config(there seems to be many changes), if it is possible can someone email me any working xorg.conf with ati cards? mine is a r380 X600 Radeon...the email address is dritan30@hotmail.com or dritan30@gmail.com, please PM me if you do so i can check...thanks in advance

EDIT: hmm...it seems like a 100% xorg issue as it does not start with the gentoo-sources which worked fine at xorg-6.8...i'd probably look for a xorg-7 specific post to try to solve this...but of course...if someone could help me from here i'd be more than happy
