Got a black screen when I tried to boot it - it could be that fbsplash didn't work, but I didn't hear the harddrive spin so it sounds like an instant lockup. Yeah correcting scheduler code is propably something that only the author of it can do - I wasn't asking for you to correct it :) (just meant the compile error - which unfortunately didn't help, thanks for taking the time to fix it anyway though). For single CPU systems with reiser4 this release sounds really good though :)

couple of no-sources guys got wind about all their nicksched work that was borrowed. they didn't complain, but they were a bit annoyed that no credit was given to them. anyways, they would like a little bit of credit, if you did borrow some code from them. joecool really spent a lot of time porting nicksched.

BTW: it appears, nick peggin DOES in fact keep his schedular up to date, however only to people who request it.

Nick Piggin was done some syncing. New version is done by Him.
Now I only do little smp fix and BASE_TIMESLICE tune for better interactivity as Nick said for new release. I think new release may be some suprise hehe.
vivid has mm and nom-mm line, I do not have proper time to do every release at the same time

but I think everything is possible and I want to do mm release also

much prior is non-mm release , cause as We see mm is pretty problematic. a lot of vivid mm releases had more problems thatn non-mm.

cheers.

I tried to erase cdrw in k3b. When I pushed a button to erase cdrw my box rebooted.
I use kernel-2.6.11-rc3-vivid1.

kernel-2.6.11-rc1-vv_e4 - this kernel works normaly with erase's operation

As some People see I made also 2.6.11-rc4-love1 release and it`s similar to vivid.
Please test ( If You will

) as this "full working SMP/non-SMP" release.
It not means that I leave vivid - it`s important project for me and Troll, will be next vivid releases also.

Ideas,Concepts,Cooperation as always will be welcome

I will made some stuff for vividserv now.

cheers.

2.6.11-rc4-love1 working fine here with a p4 (SMP/SMT) - seems to have alot less problems with my reiser4 partition. Neat :)

Btw fallow, what's randomisation? Just noticed that it's a new config option, but there's no help available for it (it's also shown @ dmesg). I mean, it obviously randomises something, but what?

edit:

Oops, seems like it was too early to say... It just locked up after about 5 hours of uptime. Nothing strange in any logs. :(

edit: the other 2.6.11-rc based kernel I tried also locked up the same way (ck) - so it's possible that this isn't scheduler related at all.

Fallow, with you now doing both Love-sources and vivid-sources, I dont' know which I should use. (Before I switched to vivid-sources I was a love user.) What's the difference between them? The patchsets look rather similar. Just glancing at the love-sources pathset it would appear it's a bit more aggressive than vivid, but I'm not sure what all those do, so I don't know.

And out of curiosity, what made you decide to get involved with love-sources?

fallow · Posted: Mon Feb 21, 2005 2:12 pm Post subject:

love-sources has a good tradition and long history. is still many of people and users at #love-sources channel and the love-community is really nice. so I think is very nice to continue it and will be many of new releases.

I don`t think that I will have proper time to do paraller both sources,but I want to vivid will exist further.
Maybe Troll or somebody will have proper time for it

?

I think that we will establish overall form at the #

cheers.

About IO Schedulars. I use deadline along with JACK and a mixture of realtime xfs and reiser4fs parititions on a single SATA drive. The machine is a low latency desktop that runs some nippy server software.

I added this to /etc/sysctl.conf after reading up on it on IBM and then playing for a weekend.

vm.dirty_background_ratio = 3
vm.dirty_expire_centisecs = 300
vm.dirty_ratio = 1
vm.dirty_writeback_centisecs = 60
vm.laptop_mode = 0

The vm.laptop_mode doesn't work too well with JACK under Realtime XFS - but I'd recommend giving it a go on non-laptops otherwise.

I also do a

echo 16 > /sys/block/sda/queue/iosched/fifo_batch
echo 1 > /sys/block/sda/queue/iosched/front_merges
echo 300 > /sys/block/sda/queue/iosched/read_expire
echo 300 > /sys/block/sda/queue/iosched/write_expire
echo 16 > /sys/block/sda/queue/iosched/writes_starved

every reboot to sort out my IO Schedular for simultaneous server and low latency (so low latency server which will probably die a DOS death someday - hopefully not before I figure out DOS prevention). Now my question is this: Is there an official place to put my IO Schedular stuff? Like I dunno a config file or boot loader grub config. Not really up for patching my kernel but am used to it now (Unpack IPTables + Nitro3 Recompile then emerge IPTables (patch-o-matic's profile match) + NVidia Kernel + IEEE80211 + Realtime-LSM + Alsa-Driver + NDISWrapper + HAL + ACPI, etc).

PS Try out my settings (insert disclaimer) if you wish + no liability. Try some simultaneous stuff across several windows - take a copy of your settings - echo in these ones - do a hdparm -Tt dev to sync (probably better with the sync command but not consistent accross laptop harddrives). Then try the same number of windows or more and see if the desktop remains nippy. I found the extra overhead negligable and the interface nippier than windows.
