|
||||
Overview:
|
||||
This scheduler provides weighted CPU sharing in an intuitive way and
|
||||
uses realtime-algorithms to ensure time guarantees.
|
||||
|
||||
Usage:
|
||||
-add "sched=sedf" on Xen's boot command-line
|
||||
-create domains as usual
|
||||
-use "xm sched-sedf <dom-id> <period> <slice> <latency-hint> <extra> <weight>"
|
||||
Where:
|
||||
-period/slice are the normal EDF scheduling parameters in nanosecs
|
||||
-latency-hint is the scaled period in case the domain is doing heavy I/O
|
||||
(unused by the currently compiled version)
|
||||
-extra is a flag (0/1), which controls whether the domain can run in
|
||||
extra-time
|
||||
-weight is mutually exclusive with period/slice and specifies another
|
||||
way of setting a domains cpu slice
|
||||
|
||||
Examples:
|
||||
normal EDF (20ms/5ms):
|
||||
xm sched-sedf <dom-id> 20000000 5000000 0 0 0
|
||||
|
||||
best-effort domains (i.e. non-realtime):
|
||||
xm sched-sedf <dom-id> 20000000 0 0 1 0
|
||||
|
||||
normal EDF (20ms/5ms) + share of extra-time:
|
||||
xm sched-sedf <dom-id> 20000000 5000000 0 1 0
|
||||
|
||||
4 domains with weights 2:3:4:2

xm sched-sedf <d1> 0 0 0 0 2

xm sched-sedf <d3> 0 0 0 0 4
|

xm sched-sedf <d4> 0 0 0 0 2
|

|

1 fully-specified (10ms/3ms) domain, 3 other domains share
|
||||
available rest in 2:7:3 ratio:

||||
xm sched-sedf <d1> 10000000 3000000 0 0 0
