btw I'm putting together a set of scripts that I call "syspart" (for "system
partitioning") which creates cpusets, sets up IRQ affinity, etc at boot. We
can make your init replacement a part of that package. You could then tell
people to
1. Install syspart rpm
2. Change boot opts to "init=/sbin/syspart par0_cpus=0-3 par0_mems=0-2 par0_init"
The thing will then create /dev/cpuset/par0 with cpus0-3 and mems0-2 and put
/sbin/init into that cpuset.
With the exception of the #1 it's as easy to explain as "isolcpus=".
Paul, I beleive you mentioned a while ago that the tools you guys use for this
aren't open source. Has that changed ? If not I'll write my own. I have all
the scripts ready to go but as you pointed out it has to be a standalone
statically linked binary.
Thanx
Max
