[Xen-devel] [PATCH] tunable time slice for credit scheduler

[Atsushi SAKAI <sakaia@xxxxxxxxxxxxxx>]

Hi,

This patch intends to add tunablity for time slice on credit scheduler.
Each domain can change time slice. 

for example, 
xm sched-credit -d 0 -s 20
(unit is msec)

Signed-off-by: Atsushi SAKAI <sakaia@xxxxxxxxxxxxxx>

c.f.
1)libxc(pyxc) forgets help message for cap.
I add it on tools/python/xen/lowlevel/xc/xc.c

2)time slice can set from 1 to 100(msec).
I have see VNC connection timeout problem for many domain on one CPU.
For this reason, it can set time slice from 1 to 100 msec.
Of course, default value is 30msec.


Thanks
Atsushi SAKAI
