[Xen-devel] how Change cap when cap != 0U ?

[developerxen <developerxen@xxxxxxxxx>]

Hello,

I examined this code of credit. i have to two question?

1. what mean variable credit_cap?

2. how set cap per-vcpu in this code?!

in computation credit_cap if sdom->cap =20 result credit_cap = 60 :-|

are credit_cap Equal to sdom->cap?! why should credit_cap divide sdom->active_vcpu_coun?!

        if ( sdom->cap != 0U )

       

            credit_cap = ((sdom->cap * CSCHED_CREDITS_PER_ACCT) + 99) / 100;

            if ( credit_cap < credit_peak )

                credit_peak = credit_cap;

            /* FIXME -- set cap per-vcpu as well...? */

            credit_cap = ( credit_cap + ( sdom->active_vcpu_count - 1 )

                         ) / sdom->active_vcpu_count;

        }
