From 1a9167a214f560a23c5050ce6dfebae489528f0d Mon Sep 17 00:00:00 2001 From: Fabiano Rosas Date: Wed, 19 Jun 2019 13:01:27 -0300 Subject: KVM: PPC: Report single stepping capability When calling the KVM_SET_GUEST_DEBUG ioctl, userspace might request the next instruction to be single stepped via the KVM_GUESTDBG_SINGLESTEP control bit of the kvm_guest_debug structure. This patch adds the KVM_CAP_PPC_GUEST_DEBUG_SSTEP capability in order to inform userspace about the state of single stepping support. We currently don't have support for guest single stepping implemented in Book3S HV so the capability is only present for Book3S PR and BookE.
