14:44<TSquirrel:#uml>hi there
14:45<TSquirrel:#uml>can someone help me with uml?
14:45<caker:#uml>!ask
14:45<linbot:#uml>Don't ask to ask; just ASK
14:46<caker:#uml>also, this better be user mode linux related, or else!
14:46<thomas_adam:#uml>Heh.
14:46<TSquirrel:#uml>i have to classes
14:46<caker:#uml>WRONG
14:46<TSquirrel:#uml>one inherits from the other
14:46<caker:#uml>TSquirrel: check /topic :)
14:47<thomas_adam:#uml>I was just about to ask how common methodology questions were. ;)

14:53<thomas_adam:#uml>Well, I got SKAS3 to compile against 2.6.30.
15:20<caker:#uml>!cyborg jdike
15:20<linbot:#uml>caker: J.D.I.K.E.: Juggernaut Designed for Immediate Killing and Exploration
15:20<jdike:#uml>uh oh
15:20<jdike:#uml>they figured me out

16:42<DHowett:#uml>thomas_adam, SKAS3-2.6.30 you say
16:42<DHowett:#uml>hmm..
16:42<DHowett:#uml>meh, i'd be more interested if I could actually get UML to compile :P
16:42<thomas_adam:#uml>Seemingly. Had to mash up bits of it though. Still compiling.
16:42<DHowett:#uml>ahh
16:44<DHowett:#uml>D'you know if that weird "horrible slowness on 2.6.28 for some reason" bug got fixed in mainline?
16:44<DHowett:#uml>I believe it was a host kernel issue
16:45<thomas_adam:#uml>I'm currently using 2.6.28 with SKAS3, and six UML instances; there's no slowness here.
16:45<DHowett:#uml>hrm :P alright, thanks
16:45<DHowett:#uml>I couldn't get a uml guest to build, so i ended up just building for x86_64 and using qemu :-/
16:46<thomas_adam:#uml>What problems were you haviong?
16:47<DHowett:#uml>It died linking .tmp_vmlinux1:
16:47<DHowett:#uml>/usr/lib/gcc/x86_64-pc-linux-gnu/4.2.4/../../../../x86_64-pc-linux-gnu/bin/ld:arch/um/kernel/vmlinux.lds:1: ignoring invalid character `#' in expression
16:49<thomas_adam:#uml>I am not on a x86_64 machine, alas.
16:49<DHowett:#uml>aye, thanks anyway :)
16:55<thomas_adam:#uml>DHowett: http://www.kuzuore.com/~kuzu/diary/?date=20090411 -- familiar?
16:56<DHowett:#uml>yep, exactly
16:56<DHowett:#uml>I even think the page is ;)

20:22<thomas_adam:#uml>OK, so this SKAS3 patch for 2.6.30 seems to work OK.
20:24<DHowett:#uml>Is there a published skas3 patch for 2.6.29? Or does the one from 2.6.28 work fine
20:25<thomas_adam:#uml>The one from 2.6.28 won't work fine.
20:25<thomas_adam:#uml>Neither will mine for 2.6.30 -- you'll have to bodge your own.
20:27<thomas_adam:#uml>Plus I am not interested in 2.6.29 anyway at this stage.
20:38<DHowett:#uml>hehe
20:38<DHowett:#uml>i could just go to 2.6.30, i love -rc anyway :P
20:52<thomas_adam:#uml>Can't you run in SKAS0 mode?
20:57<thomas_adam:#uml>Why was it the "new" UML pages were ever replaced with the "old site"? At least the old site *has* useful information on it. It should still be the default.
21:06<DHowett:#uml>It looks from the outside like the project is dead
21:06<thomas_adam:#uml>No, it's not dead.
21:06<DHowett:#uml>Oh, I know
21:07<DHowett:#uml>and i'll be honest, i'm not 100% clear on SKAS0 vs SKAS3, I just vaguely remember reading some pages about it
21:10<caker:#uml>a moderm UML kernel will run in skas0 mode on an unmodified host. skas3 is *slightly* more performant, but skas0 works well.
21:11<thomas_adam:#uml>As soon as I get a wiki account I will start updating stuff.
21:11<thomas_adam:#uml>There's so many dead links on the wiki alone it's untrue.
21:13<thomas_adam:#uml>Well, I wouldn't recommend an unpatched host without SKAS3 if it's going to be doing serious work.
21:15<thomas_adam:#uml>I've seen a lot of performance increases from SKAS0 -> SKAS3 on the host, and I use UML daily at work as a "virtualisation" solution.
21:32<thomas_adam:#uml>jdike: I appreciate you're perhaps too busy to reply to email, but... SKAS{3,4} stuff? ;)
