Subject: [ANNOUNCE][RFC] PlugSched-6.4 for  2.6.19

This version removes the hard/soft CPU rate caps from the SPA schedulers.

A patch for 2.6.19 is available at:

<http://prdownloads.sourceforge.net/cpuse/plugsched-6.4-for-2.6.19.patch?download>

Very Brief Documentation:

You can select a default scheduler at kernel build time.  If you wish to
boot with a scheduler other than the default it can be selected at boot
time by adding:

cpusched=<scheduler>

to the boot command line where <scheduler> is one of: ingosched,
ingo_ll, nicksched, staircase, spa_no_frills, spa_ws, spa_svr, spa_ebs
or zaphod.  If you don't change the default when you build the kernel
the default scheduler will be ingosched (which is the normal scheduler).

The scheduler in force on a running system can be determined by the
contents of:

/proc/scheduler

Control parameters for the scheduler can be read/set via files in:

/sys/cpusched/<scheduler>/
