atropos scheduler params

[Diwaker Gupta <diwakergupta@gmail.com>]

Hi folks,

I'm trying to use the atropos scheduler with Xen. Couple of questions:

- the scheduling param *has* to be specified at boot time right, or
does Xen allow changing the scheduling scheme at run time??

- xm help atropos gives a very vague message at best, perhaps we could
make it more elaborate:

xm atropos DOM SLICE PERIOD LATENCY XTRATIME

o is DOM the vm ID or the vm NAME (as appearing in xm list)
o SLICE, PERIOD are in nanoseconds I believe?
o XTRATIME has to be 1/0 ?
o some examples with typical values would be great

Finally, I'm passing sched param to Xen at boot time as:
kernel /boot/xen.gz dom0_mem=65536 sched=atropos

But the machine failts to boot with a "CPU 0 is toasted" type of
message! :-O If remove the sched param, things work just fine again.
Any ideas?

Thx
