From: Bharat Bhushan <bharat.bhushan@xxxxxxxxxxxxx> This patchset adds the userspace debug support for booke/bookehv. this is tested on powerpc e500v2/e500mc devices. We are now assuming that debug resource will not be used by kernel for its own debugging. It will be used for only kernel user process debugging. So the kernel debug load interface during context_to is used to load debug conext for that selected process. v2->v3 - We are now assuming that debug resource will not be used by kernel for its own debugging. It will be used for only kernel user process debugging. So the kernel debug load interface during context_to is used to load debug conext for that selected process. v1->v2 - Debug registers are save/restore in vcpu_put/vcpu_get. Earlier the debug registers are saved/restored in guest entry/exit Bharat Bhushan (7): KVM: PPC: debug stub interface parameter defined Rename EMULATE_DO_PAPR to EMULATE_EXIT_USER KVM: extend EMULATE_EXIT_USER to support different exit reasons booke: exit to user space if emulator request KVM: PPC: exit to user space on "ehpriv" instruction powerpc: export debug register save function for KVM KVM: PPC: Add userspace debug stub support arch/powerpc/include/asm/kvm_host.h | 8 + arch/powerpc/include/asm/kvm_ppc.h | 2 +- arch/powerpc/include/asm/switch_to.h | 4 + arch/powerpc/include/uapi/asm/kvm.h | 37 +++++ arch/powerpc/kernel/process.c | 3 +- arch/powerpc/kvm/book3s.c | 6 + arch/powerpc/kvm/book3s_emulate.c | 4 +- arch/powerpc/kvm/book3s_pr.c | 4 +- arch/powerpc/kvm/booke.c | 239 ++++++++++++++++++++++++++++++++-- arch/powerpc/kvm/booke.h | 5 + arch/powerpc/kvm/e500_emulate.c | 10 ++ arch/powerpc/kvm/powerpc.c | 6 - 12 files changed, 304 insertions(+), 24 deletions(-) -- 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
