This is the framework for using XIVE in a PowerVM guest. The support is very similar to the native one in a much simpler form. Instead of OPAL calls, a set of Hypervisors call are used to configure the interrupt sources and the event/notification queues of the guest: H_INT_GET_SOURCE_INFO H_INT_SET_SOURCE_CONFIG H_INT_GET_SOURCE_CONFIG H_INT_GET_QUEUE_INFO H_INT_SET_QUEUE_CONFIG H_INT_GET_QUEUE_CONFIG H_INT_RESET Calls that still need to be addressed : H_INT_SET_OS_REPORTING_LINE H_INT_GET_OS_REPORTING_LINE H_INT_ESB H_INT_SYNC
So, does this mean there's a PAPR update with the XIVE virtualization stuff? Or at least an ACR? Can we have that available please... -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
