2.6.18-emission1: Pathological Euphoria

vipernicus · 2.6.18-emission1: Pathological Euphoria

E-Mission Sources is based on the Lockless Pagecache by Nick Piggin, GenPatches, and CK.

The main goal of this patchset is to stay updated with genpatches releases,
offer latest features, decrease latencies, decrease overhead, and improve interactivity. Another
goal of E-Mission Sources is stability. We boot test each release and run for an extended amount of time.

/* Notes */
New versions of everything! I decided to go ahead and release -emission1 with execshield for this release. GrSecurity is taking their time in releasing a new version.

Features:
RCU-Preempt: Lower Latencies http://lkml.org/lkml/2006/8/28/179
USB Mouse Polling Revised: Predatorfreak changed the patch up slightly to allow you to change your polling interval in sysctl, at '/proc/sys/kernel/hid_mousepoll_interval'. You now have the option of enabling or disabling polling in favor of the event based system, which is the kernel default.
Adaptive Readahead: New readahead logic, improved speed: http://kerneltrap.org/node/6642
Genetic Anticipatory: Alot of work has been done, and bugs have been fixed. Good for File Servers/Databases. http://kernel.jakem.net/
Thinkpad patches: http://vipernicus.evolution-mission.org/patches/2.6.18/emission1/patches/thinkpad
BadRAM: Work around bad spots in RAM http://rick.vanrein.org/linux/badram/
Libata-git: Latest for SATA and PATA

Attention:
If anyone would like to make requests for new features/drivers, either post here, or join us in #emission-sources on Freenode.

Example of new E-Mission Tunables (All but Custom are preconfigured options):

There is a small typo in your manual instructions

cd /usr/src
rm linux
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.18.tar.bz2
tar -xvjf linux-2.6.18.tar.bz2
mv linux-2.6.18 linux-2.6.18-emission1
ln -s linux-2.6.17-emission1 linux
cd linux
wget http://distfiles.evolution-mission.org/sources/2.6.18/emission1/linux-2.6.18-emission1.bz2
bzcat linux-2.6.18-emission1.bz2 | patch -p1
rm -rf *.bz2 *.patch
make MENUCONFIG_COLOR=blackbg menuconfig

i have this in my dmesg;

Memory: 2073372k/2096320k available (2510k kernel code, 21844k reserved, 923k data, 168k init, 0k highmem, 0k BadRAM)

the high memory was set to off. but i set the 2G/2G split all the same. As the dmesg shows everything went fine.

i just felt viper should know.

Just to make sure.

BadRAM does not work with High Memory Support?

If this is the case, I need to set it up to where it is only selectable in absence of High Mem.

vipernicus, glad to see that I'm not the only one that had issues with the BadRAM patch. I also had it set to high memory support and got an identical error when testing this earlier if you recall.

i'm getting a kernel panic with this one with something like;

maybe I have the same problem with via-sata, I have compiled the kernel smothly, but during the boot process it shows kernel panic while initializing sata, works ok in rad1-sources, maybe there is something wrong in the libata-GIT:(

yeah, I'm going to install it when I get back home

kernelOfTruth · Posted: Fri Oct 06, 2006 10:36 am Post subject:

ok, some more feedback:
it works fine & stable on my laptop (at least 2 hours of lecture), it feels pretty responsible (thanks to preemption

)
I hope that you soon will bring out the fix for badmem-patch

I'm probably going to release two HotFix patches later tonight, one to fix badmem, and one to reverse libata-git for those who have problems with it.

libata working fine here, it's running now on my box (x86), JMicron works so far, no lockups, will try some hard work later [with highmem deactivated] :wink:

ok, I'm going to install it on amd64 now, hopefully unionfs builds fine ... :roll:
