[Qemu-devel] [PATCHv2 1/3] target-ppc: Split out SREGS get/put functions

Currently the getting and setting of Power MMU registers (sregs) take up large inline chunks of the kvm_arch_get_registers() and kvm_arch_put_registers() functions. Especially since there are two variants (for Book-E and Book-S CPUs), only one of which will be used in practice, this is pretty

fa48b43 "target-ppc: Remove hack for ppc_hash64_load_hpte*() with HV KVM" purports to remove a hack in the handling of hash page tables (HPTs) managed by KVM instead of qemu. However, it actually went in the wrong direction. That patch requires anything looking for an external HPT (that is one

[Qemu-devel] [PATCHv2 2/3] target-ppc: Add helpers for updating a CPU's SDR1 and external HPT

When a Power cpu with 64-bit hash MMU has it's hash page table (HPT) pointer updated by a write to the SDR1 register we need to update some derived variables. Likewise, when the cpu is configured for an external HPT (one not in the guest memory space) some derived variables need to be updated.

[Qemu-devel] [PATCHv2 0/3] target-ppc: Clean up handling of SDR1 and external HPTs

These patches cleans up handling of SDR1 (master page table pointer register for Power) and related cases with an external (i.e. managed by qemu or KVM, rather than the guest) hash page table (HPT). I wouldn't push 1/3 or 2/3 on their own after the soft freeze, except that they simplify 3/3,
