Re: [Xen-users] xl doesn't honour the parameter cpu_weight from my config file while xm does honour it

[Dieter Bloms <dieter@xxxxxxxx>]

Hello Ian,

I've made a little patch to set the cpu_weight for credit, credit2 and
sedf scheduler from the config file.

Btw.: for the sedf scheduler there seems to be some type mismatch.  
The functions xc_sedf_domain_set and xc_sedf_domain_get expect the type
'uint16_t' for variables 'extratime' and 'weight' while the structure
'xen_domctl_sched_sedf' defines the type uint32_t for them.
I think they should be the same, or not ?

Anyway, I've tested this patch for the credit scheduler and it works so
far.
