The different XIVE virtualization structures (sources and event queues) are configured with a set of Hypervisor calls : - H_INT_GET_SOURCE_INFO used to obtain the address of the MMIO page of the Event State Buffer (ESB) entry associated with the source. - H_INT_SET_SOURCE_CONFIG assigns a source to a "target". - H_INT_GET_SOURCE_CONFIG determines which "target" and "priority" is assigned to a source - H_INT_GET_QUEUE_INFO returns the address of the notification management page associated with the specified "target" and "priority". - H_INT_SET_QUEUE_CONFIG sets or resets the event queue for a given "target" and "priority". It is also used to set the notification configuration associated with the queue, only unconditional notification is supported for the moment. Reset is performed with a queue size of 0 and queueing is disabled in that case. - H_INT_GET_QUEUE_CONFIG returns the queue settings for a given "target" and "priority". - H_INT_RESET resets all of the guest's internal interrupt structures to their initial state, losing all configuration set via the hcalls H_INT_SET_SOURCE_CONFIG and H_INT_SET_QUEUE_CONFIG. - H_INT_SYNC issue a synchronisation on a source to make sure all notifications have reached their queue. Calls that still need to be addressed : H_INT_SET_OS_REPORTING_LINE H_INT_GET_OS_REPORTING_LINE See the code for more documentation on each hcall.
