[Qemu-devel] [PATCH 1/2] spapr/xive: rework the mapping the KVM memory regions

2019-06-14 Thread Cédric Le Goater
Today, the interrupt device is fully initialized at reset when the CAS negotiation process has completed. Depending on the KVM capabilities, the SpaprXive memory regions (ESB, TIMA) are initialized with a host MMIO backend or a QEMU emulated backend. This results in a complex initialization sequenc
