/me wails "All along the watchtowers"

Oh yes... I promised you I would finish -love1 and here it is:

Basically -love1pre updated to -mm4, I added the runtime selectable io scheduler patch, so now you need to add

echo cfq > /sys/block/hda/queue/io_scheduler

to /etc/conf.d/local.start

of course valid options are cfq, anticpatory, deadline and noop - you can query the current scheduler on a block device by catting the same interface.

you can set different schedulers for each block device on your system, just replace the hda bit with the device you need to change.

As usual I picked up a few minor patches on lkml to fix problems and memory leaks.

- ebuild will follow as soon as I recall where I put the damn thing, and get ssh to behave.

The link isn't found.

If you want I can mirror it on my webserver, although it would just get 400 kbps (50kB/s) upstream it would help take the load off your server.

It would be a secondary mirror at best cause it is just on an AMD Tbird 1400 on a DSL line.

I could also see about mirroring it on my univeristies Unix server, I think every student gets a free amount of webspace

Hey, I gotta give back to love sources somehow :p

Great! I will test it when I have time (running 2.6.0-test6-mm4 now).
Unfortunate that the people at namesys won't release a snapshot though. I would love to try it out on a temporary partition, but the latest snapshots won't compile, and further back I won't dare to touch it. I reported the bug, and though it should be fixed upstream, I'm not able to see the results :(

As stated previously supermount is an EVIL implementation of a nice idea - this type of stuff MUST be done in userspace.. so make it apply to love sources and I'll include it, but if I have to do real world to include a feature I don't even like then forget it.

Sorry, but I'm the evil dicator.

It should be as great as ever - mainly the important bit for test6-love1 was getting the runtime selectable IO scheduler stuff in... and I must say it's one of my favorite features ever.

I love that I can set the right scheduler for the right block device - something that doesn't benefit from all this scheduling nonsense like a flash device can just go noop without affecting anything else.. it's so great..

sysfs is the best thing since sliced bread.

I was more of kidding, I already read your reasons for disliking supermount, what do you suggest in the userspace domain which would replace supermount?

hmmm, I found this one, submount, it looks basically the same as supermount but slightly different (if that made any sense) anyone tried it?

ok. compiled it, rebooted. seems to run fine.
passes the browser-window-wiggle-xmms-
no-skip test just fine. i am not sure about
those new options available by passing things
to io_scheduler; i do not know what i may
do with them; i just chose the cfg one as
you suggested.

latest snapshot of submount is as I recall very old - I like the project though... pre kernel 2.6.. not very useful.

it's mainly meant for having seperate schedulers on different devices - stuff that doesn't benefit form scheduling shouldn't be wasted resources upon.

Sorry guys,

I downloaded the patch file, but a dry run on the 2.6.0-test6 source
tree gives

patching file sound/pci/cmipci.c
patching file sound/pci/intel8x0.c
patch unexpectedly ends in middle of line
patch unexpectedly ends in middle of line

Did I miss part of the file! The one I have is
717k

Thanks

let me guess you used the command

bzip2 -dc /home/ryan/Desktop/2.6.0-test6-love1.patch | patch -p1 --dry-run

I got the same error, I just unbzipped it and used.

cat /home/ryan/Desktop/2.6.0-test6-love1.patch | patch -p1 --dry-run

Of course you don't have to cat it but it never seems to work if I do otherwise (will come up asking me a bunch of questions regarding what stuff to stick where that I just don't know).

nope, long standing issue - for some reason my patch gives that output, nobody has been able to spot the mistake.. but it's completely harmless.

Anyone wanna offer up a solution?

Thank you lovechild.

I have mirrored it here:
http://ajax.kfunigraz.ac.at/~gantner/stuff/2.6.0-test6-love1.patch.bz2
Feel free to add as mirror to original post. It's my universities webserver, so I guess no worries about bandwidth.
Note that I untarred and rebzip2ed it, hence the different name (misconfigured webserver corrupts .tar files on download). No need to tar a single file anyway is there ;)

Can someone either give me a very dumbed down description of what the scheduler does/how it works, or point me to a dumbed down version?

I think I get it, but I'm not sure, and I'm just confusing myself now :p.
