[Xen-devel] [PATCH v2 1/5] xen:rtds: towards work conserving RTDS

2017-09-01 Thread Meng Xu
Make RTDS scheduler work conserving without breaking the real-time guarantees. VCPU model: Each real-time VCPU is extended to have an extratime flag and a priority_level field. When a VCPU's budget is depleted in the current period, if it has extratime flag set, its priority_level will increase by
