Upon such\nmachine check exception, if the address in error belongs\nto guest then KVM causes a guest exit with KVM_EXIT_NMI\nexit reason.\n\nThis patch series adds functionality to pass on such\nmachine check exception to the guest kernel by suitably\nhandling KVM_EXIT_NMI exit and building the error log.\n\nThe KVM changes are now part of the upstream kernel\n(commit e20bbd3d). This series contain QEMU changes.\n\nChange Log v5:\n - Handled VM migrations by including rtas_addr in VMSTATE.\n - Migration is blocked while a machine check is in progress.\n\nChange Log v4:\n - Included the RTAS_DISP_FULLY_RECOVERED scenario in\n patch 4/5.\n\nChange Log v3:\n - Rebased to v2.10.0-rc0 (git://github.com/dgibson/qemu)\n\nChange Log v2:\n - Added KVM capability\n - Serialized multiple NMIs with a conditional wait\n\n---\n\nAravinda Prasad (6):\n ppc: spapr: Register and handle HCALL to receive updated RTAS region\n ppc: spapr: Handle \"ibm,nmi-register\" and \"ibm,nmi-interlock\" RTAS calls\n Wrapper function to wait on condition for the main loop mutex\n target/ppc: Handle NMI guest exit\n ppc: spapr: Enable FWNMI capability\n migration: Block migration while handling machine check\n\n\n cpus.c | 5 +++\n hw/ppc/spapr.c | 23 ++++++++++++\n hw/ppc/spapr_events.c | 62 +++++++++++++++++++++++++++++++\n hw/ppc/spapr_hcall.c | 8 ++++\n hw/ppc/spapr_rtas.c | 53 +++++++++++++++++++++++++++\n include/hw/ppc/spapr.h | 23 +++++++++++-\n include/qemu/main-loop.h | 8 ++++\n target/ppc/kvm.c | 92 ++++++++++++++++++++++++++++++++++++++++++++++\n target/ppc/kvm_ppc.h | 20 ++++++++++\n 9 files changed, 292 insertions(+), 2 deletions(-)\n\n--\nAravinda Prasad" }
