[PATCH v3 5/6] KVM: PPC: Add support for nestedv2 guests

A series of hcalls have been added to the PAPR which allow a regular guest partition to create and manage guest partitions of its own. KVM already had an interface that allowed this on powernv platforms. This existing interface will now be called "nestedv1". The newly added PAPR interface will be

[PATCH v3 4/6] KVM: PPC: Book3s HV: Hold LPIDs in an unsigned long

The LPID register is 32 bits long. The host keeps the lpids for each guest in an unsigned word struct kvm_arch. Currently, LPIDs are already limited by mmu_lpid_bits and KVM_MAX_NESTED_GUESTS_SHIFT. The nestedv2 API returns a 64 bit "Guest ID" to be used be the L1 host for each L2 guest. This

[PATCH v3 3/6] KVM: PPC: Add helper library for Guest State Buffers

The PAPR "Nestedv2" guest API introduces the concept of a Guest State Buffer for communication about L2 guests between L1 and L0 hosts. In the new API, the L0 manages the L2 on behalf of the L1. This means that if the L1 needs to change L2 state (e.g. GPRs, SPRs, partition table...), it must

[PATCH v3 1/6] KVM: PPC: Use getters and setters for vcpu register state

There are already some getter and setter functions used for accessing vcpu register state, e.g. kvmppc_get_pc(). There are also more complicated examples that are generated by macros like kvmppc_get_sprg0() which are generated by the SHARED_SPRNG_WRAPPER() macro. In the new PAPR "Nestedv2" API

[PATCH v3 0/6] KVM: PPC: Nested APIv2 guest support

A nested-HV API for PAPR has been developed based on the KVM-specific nested-HV API that is upstream in Linux/KVM and QEMU. The PAPR API had to break compatibility to accommodate implementation in other hypervisors and partitioning firmware. The existing KVM-specific API will be known as the
