In an effort to get KVM on PPC more useful for other userspace users than Qemu, I figured it'd be a nice idea to implement virtualization of the Gekko CPU. The Gekko is the CPU used in the GameCube. In a slightly more modern fashion it lives on in the Wii today. Using this patch set and a modified version of Dolphin, I was able to virtualize simple GameCube demos on a 970MP system. As always, while getting this to run I stumbled across several broken parts and fixed them as they came up. So expect some bug fixes in this patch set too. v1 -> v2: - rename REG_ constants to KVM_REG_ - make mmio sign extension more readable - replace binary patching emulator with function calls - add capability bit - make fpscr 64 bit wide - add secondary htab patch - make fpu work on ps3 again Alexander Graf (21): KVM: PPC: Add QPR registers KVM: PPC: Make fpscr 64-bit KVM: PPC: Enable MMIO to do 64 bits, fprs and qprs KVM: PPC: Teach MMIO Signedness KVM: PPC: Add AGAIN type for emulation return KVM: PPC: Add hidden flag for paired singles KVM: PPC: Add Gekko SPRs KVM: PPC: Combine extension interrupt handlers KVM: PPC: Preload FPU when possible KVM: PPC: Fix typo in book3s_32 debug code KVM: PPC: Implement mtsr instruction emulation KVM: PPC: Make software load/store return eaddr KVM: PPC: Make ext giveup non-static KVM: PPC: Add helpers to call FPU instructions KVM: PPC: Fix error in BAT assignment KVM: PPC: Add helpers to modify ppc fields KVM: PPC: Enable program interrupt to do MMIO KVM: PPC: Implement Paired Single emulation KVM: PPC: Add capability for paired singles KVM: PPC: Enable use of secondary htab bucket KVM: PPC: Simplify kvmppc_load_up_(FPU|VMX|VSX) arch/powerpc/include/asm/kvm.h | 7 + arch/powerpc/include/asm/kvm_asm.h | 1 + arch/powerpc/include/asm/kvm_book3s.h | 7 +- arch/powerpc/include/asm/kvm_fpu.h | 85 ++ arch/powerpc/include/asm/kvm_host.h | 8 +- arch/powerpc/include/asm/kvm_ppc.h | 39 +- arch/powerpc/include/asm/reg.h | 10 + arch/powerpc/kernel/ppc_ksyms.c | 2 + arch/powerpc/kvm/Makefile | 2 + arch/powerpc/kvm/book3s.c | 118 +++- arch/powerpc/kvm/book3s_32_mmu.c | 2 +- arch/powerpc/kvm/book3s_64_emulate.c | 94 ++- arch/powerpc/kvm/book3s_64_mmu_host.c | 9 +- arch/powerpc/kvm/book3s_64_rmhandlers.S | 13 +- arch/powerpc/kvm/book3s_paired_singles.c | 1289 ++++++++++++++++++++++++++++++ arch/powerpc/kvm/emulate.c | 18 +- arch/powerpc/kvm/fpu.S | 274 +++++++ arch/powerpc/kvm/powerpc.c | 54 ++- include/linux/kvm.h | 1 + 19 files changed, 1976 insertions(+), 57 deletions(-) create mode 100644 arch/powerpc/include/asm/kvm_fpu.h create mode 100644 arch/powerpc/kvm/book3s_paired_singles.c create mode 100644 arch/powerpc/kvm/fpu.S -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
