[Xen-research] Custom Xen Real-Time Scheduler

["Paul Harvey" <stockingpaul@xxxxxxxxxxx>]

Hi All,

 

I am beginning work on a real time scheduler for Xen. I am wanting to prioritise which domain to run on the outstanding time before a domain will be interrupted, either by the periodic timer in Xen or any outstanding one shot timers that the domain has registered.

 

I have just started and i was wondering if someone could give me an overview of the one shot timer process, ie where the hypercall enters the kernel and stores the outstanding requests from the domains.

 

I realise that this may be obvious to people out there who know the code backwards however as i have just started it is a little daunting at the moment.

 

Thanks

Paul
