Guests accessing emulated MMIO can do so using a wide variety of load and store instructions on PPC machines. However, KVM currently only knows about a subset of the load and store instructions available. This patchset expands the set of load and store instructions that KVM can emulate to include all of the integer loads and stores (except those that trap when used on cache-inhibited mappings), all of the floating-point loads and stores and all of the VSX loads and stores defined in the Power ISA v2.07B (which is the architecture for POWER8). This does not implement Altivec/VMX loads and stores or the new loads and stores defined in Power ISA v3.00. This patch set is against v4.11-rc3. --- arch/powerpc/include/asm/disassemble.h | 5 + arch/powerpc/include/asm/kvm_host.h | 23 ++ arch/powerpc/include/asm/kvm_ppc.h | 10 + arch/powerpc/include/asm/ppc-opcode.h | 58 ++++ arch/powerpc/kvm/Makefile | 2 +- arch/powerpc/kvm/book3s.c | 18 ++ arch/powerpc/kvm/booke.c | 5 + arch/powerpc/kvm/emulate_loadstore.c | 472 ++++++++++++++++++++++++++++++--- arch/powerpc/kvm/powerpc.c | 317 +++++++++++++++++++++- 9 files changed, 862 insertions(+), 48 deletions(-)
