Hi,
I created my first patch set today. It's based on the ck patch set with some additional patches (lirc, bootsplash, vesafb-tng, win4lin, squashfs, ..)
| Code: |

How to install
Create a portage overlay directory if you haven't done it before:
| Code: |
mkdir /usr/local/portage
|
Edit your /etc/make.conf file and point the PORTDIR_OVERLAY variable to your portage overlay directory:
| Code: |
PORTDIR_OVERLAY="/usr/local/portage"
|
Create the necessary directories if they doesn't exist:
| Code: |
mkdir /usr/local/portage/sys-kernel
mkdir /usr/local/portage/sys-kernel/nitro-sources
|
Now put the ebuild file in /usr/local/portage/sys-kernel/nitro-sources
and do this:
| Code: |
ebuild /usr/local/portage/sys-kernel/nitro-sources/nitro-sources-2.6.8_rc2-r2.ebuild digest
|
Now emerge:
| Code: |
emerge nitro-sources
|
After this, /usr/src/linux-2.6.8-rc2-nitro2 is created. Copy over your old .config file of your previous kernel and make a symlink:
| Code: |
cp /usr/src/linux/.config /usr/src/linux-2.6.8-rc2-nitro2
rm /usr/src/linux
ln -sf /usr/src/linux-2.6.8-rc2-nitro2 /usr/src/linux
|
Go in to menuconfig and enable stuff that wasn't enabled before:
| Code: |
cd /usr/src/linux
make menuconfig
|
Now you can compile. There are different ways to do this, but I still do this in the old way:
| Code: |
make dep && make clean bzImage modules modules_install
|
If the compilation succeed, copy over your bzImage to your /boot partition:
| Code: |
mount /boot
cp /usr/src/linux/arch/i386/boot/bzImage /boot/nitro-sources
|
Edit your boot loader, in my case it's grub:
| Code: |
nano -w /boot/grub/grub.conf
|
and make sure you have something like this:
| Code: |
# For booting nitro-sources
title=Gentoo Linux (nitro-sources)
root (hd0,1)
kernel (hd0,1)/nitro-sources root=/dev/hda4 ro video=vesafb:ywrap,1280x1024@85 splash=silent
initrd=(hd0,1)/initrd-1280x1024
|
Reboot and watch this baby fly!
Feel free to post any comments. The next release will probably use the Hydra scheduler so you can change the scheduler settings at runtime for the ultimate tweaking experience

I see you dropped the preempt optimizations that were in the s7.A_test1 patch, also that softirq thing is bad for performance iirc, voluntary-preempt-H4 is also known to do very little and/or cause errors.
Have a nice day.

Mmm, if you have some information that may help another linux user then it may be an idea to actually help them out.
I seem to recall you doing exactly the same sort of thing with Damouse sources only a few weeks ago before you became embroiled in the ck side of the kernel.
I may remind you that linux is a 'community', not a 'gloat and slag of somebody else because they don't know as much as you'.
What do you suggest as replacements, where do you get your information from, etc, etc.
@ seppe: Good effort for your first one.  |

Thanks for the reply's. Maybe I'll update the patch set with DaMouse's suggestions, although everything runs stable here.
Oh and PickledOnion, I'm looking forward for your guide

What did I do wrong? All I said was which patches were evil and such... I stilll make damouse-sources since its pretty much the -mm version of -ck and I get things wrong, I wasn't trying to take out all his hopes and dreams.. I was just saying that those things were wrong and require correcting.
Oh and on a side note the new voluntary-preempt patches contain the softirqd thingy anyway which is enabled by setting the the /proc var to 2.

Well, I see And it is a 2.6 kernel.
| Quote: | | but I still do this in the old way |
make dep is a really old way
And now seriously - does your patchset have supermount support? If yes then I will give it a try.
BTW, it is nice that we have one more patchset - at least we have more to choose from.

Its based apon the CK patchset so it does. Tho supermount is old and bloated and I think submount or a software implementation such as ivman should replace it.

@ DaMouse:
You did nothing particularly wrong - bad timing on my part as I just saw somebody ripping into a newb (not here) for not knowing how to apply a patch and was feeling defensive about people making an effort and getting slated for it.
Accept my aplogies and see you on #ck and #love |

this release is now updated with newer versions of the staircase scheduler and voluntary preemp. SoftIRQ is left out. Reiser4 will probably be in the next release.
full list:
| Code: |
2.6.8-rc2-win4lin.patch.bz2
from_2.6.8-rc2_to_staircase7.A.bz2
s7.A_test
schedrange.diff
schedbatch2.3.diff
schediso2.3.diff
autotune_swappiness01.diff
autotune_inactivation01.diff
supermount-ng204.diff
defaultcfq.diff
config_hz.diff
patch-i386-irq_enable_spinlocks2
patch-ool-spinlocks
9000_SuSE-117-writeback-lat.patch
BadRAM-2.6.5.2.patch.bz2
lufs-0.9.7-2.6.8-rc2.patch.bz2
akpm_latency_rollup.patch
preempt-timing-2.6.8-rc2
config-nr-tty-devices.patch.bz2
write-barriers.patch
voluntary-preempt-2.6.8-rc2-bk1-ck6-H9.bz2
kernel_preempton.diff
lirc-2.6.5-20040404
menuconfig-NAME-v1.0.patch
vesafb-tng-0.9-rc3-r1-2.6.8-rc1.patch.bz2
bootsplash-3.1.4-sp3-2.6.8-rc2.patch
squashfs2.0-patch
gcloop-2.6-20040527.patch
|
If you already emerged the 'old' version of this release, just do this to remerge the new version:
| Code: |
rm /usr/portage/distfiles/patch-2.6.8-rc2-nitro2.bz2
ebuild /usr/local/portage/sys-kernel/nitro-sources/nitro-sources-2.6.8_rc2-r2.ebuild digest
emerge nitro-sources
|
Now you have to recompile your kernel (instructions are on top of this page)

Why didn't you update to Vol Preempt -I ? he versions them in the following manner: -H1 -H2... -H8 -H9 -I0 -I1 -I2 etc
So -I is more up to date than -H

I've just compiled and tried it and ... Well, the bootsplash refused to work. There was a bunch of errors (not sure - it was like | Quote: | | [something in HEX] Some text |
) before mounting local filesystems- all I managed to read was something about the scheduler. When the system had booted up, everything was sooo slow (xmms took 100% CPU usage, the sound was crappy, etc). Is it something wrong with my setup ?

You had a kernel panic, bit like a blue screen  . Search forums for gensplash

Well, when I had kernel panics with other kernels it was simpler: it wrote "kernel panic" and stopped booting.
Anyway, I an concerned there is something wrong with the scheduler - any app uses 100% CPU. I will try disabling some features and rebuilding the kernel. I hope it helps.

Sorry, I didn't test the latest changes when I posted about it here. I get as well those kernel panics, so don't use this release.

With random kernel versions, my NIC (an onboard Rhine-II, which, obviously, uses the via-rhine driver) driver cannot seem to load due to some very weird error:
| Code: | via-rhine.c:v1.10-LK1.1.20-2.6 May-23-2004 Written by Donald Becker
ACPI: PCI interrupt 0000:00:12.0[A] -> GSI 11 (level, low) -> IRQ 11
Invalid MAC address for card #0
via-rhine: probe of 0000:00:12.0 failed with error -5 |
However, my NIC driver loads fine with my current kernel -- 2.6.7-love7.
| Code: | via-rhine.c:v1.10-LK1.2.0-2.6 June-10-2004 Written by Donald Becker
ACPI: PCI interrupt 0000:00:12.0[A] -> GSI 11 (level, low) -> IRQ 11
eth0: VIA Rhine II (VT8235) at 0xb400, 00:0e:a6:99:d4:33, IRQ 11. |
Maybe this needs to be updated?.. I think I'll do some searching and see if I can find the updated driver.. |

I have an onboard Rhine and it works with all kernels. What motherboard do you have?

An ASUS A7V8X-X. FWIW, here's the relevant output of lspci:

I have the same Rhine II! It always worked for me flawlessly - from the 2.4.x days when I was using mandrake 9.1.
However, if yours works only with certain kernels then try to copy the file usr/src/linux_in_which_it_worked/drivers/net/via-rhine.c to the same subdir of another kernel source tree (not a nice solution and I don't know if it would work).
