The XIVE KVM devices now has an attribute to configure the number of interrupt servers. This allows to greatly optimize the usage of the VP space in the XIVE HW, and thus to start a lot more VMs. Only set this attribute if available in order to support older POWER9 KVM. The XIVE KVM device now re

[for-5.0 PATCH v2 0/4] spapr: Use less XIVE HW resources in KVM

On POWER9 systems, the XICS-on-XIVE and XIVE KVM devices currently allocate a bunch of VPs in the XIVE HW to accomodate the highest VCPU id that may be possibly used in a VM. This limits the number of VMs that can run with an in-kernel interrupt controller to 63 per POWER9 chip, irrespectively of i

The XIVE and XICS-on-XIVE KVM devices on POWER9 hosts can greatly reduce their consumption of some scarce HW resources, namely Virtual Presenter identifiers, if they know the maximum number of vCPUs that may run in the VM. Prepare ground for this by passing the value down to xics_kvm_connect() and
