2.6.11-rc2-nitro1: The Bear Necessities

You are mixing up two things:
io-scheduler (ie cfq, deadline anticipatory noop)
and cpu scheduler (O(1)->kernel default, staircase->ck, zaphod->nevermind)

Sorry, i mix them up time to time :oops:

but i guess that clarifies it:)

Hmm,
the answer is rather no, there is no www.realtime-preempt.com or such...

EDIT:
but have you ever wondered why your mouse might jump around the screen instead of smoothly gliding upon cpu-usage > 40% ?
or why it takes sometimes 2-3 seconds after a click on a folder until the window pops up?

the answer to the questions about it is partly in the rt: in doesn't have to be this way....
PS: i'm tearing my eyes out right now so you can try it out without the drawbacks of the first nitro-rt release (aka USE="want-realtime")

Hey all, first time using this type of kernel and i came across a few issues, one in mmap.c, i had to change:

current->rlim to current->signal->rlim this seems to have fixed my non smp systems. and now they boot fine and run. Was this a good way to fix?

BUT my smp systems give me an error on the bzimage building.

LD .tmp_vmlinux1
kernel/built-in.o(.text+0xc91): In function `try_to_wake_up':
: undefined reference to `smp_send_reschedule_allbutself'
kernel/built-in.o(.text+0x11cd): In function `finish_task_switch':
: undefined reference to `smp_send_reschedule_allbutself'
make: *** [.tmp_vmlinux1] Error 1

Can any one help please, i have tried a lot of things to fix this but this one i really do not know how to fix. I have tried a dual a64 and a dual e64t, nothing helped, disabling smp fixes this issue.

Any ideas?

annihilation: You should probably try the non-rt version then. The rt version has been known to be buggy...

the nitro website appears to be down, and i'd like to switch my kernel over. does anyone know if there's a mirror up somewhere or would anyone be able to email/dcc me the file?

Thanks for the links, I was rather begining to think the Nitro patches were dead, since I've been having trouble getting into the main page (anyone else noticed this too?)

Thanks a lot!! I'll give it a whirl on my testing system, and will most likely use the others for my production systems.
