Don't offline it.\n- CPU hotplug after the machine/main loop has been fully setup\n-- the new CPU comes up, answers and sends emergency signals, but suddenly\n the VM gets stuck. This is strange, as ordinary online/offline works\n just fine.\n-- can be triggered by \"cpu-add 1\" + \"system_reset\". The system will hang\n when trying to online CPUs. (note: in Linux code they are fully up and\n running and already executed code)\n-- also if hotplugging with \"-S\", before anything has run. This is strange,\n as \"-device qemu-s390-cpu\" works just fine.\n-- does not seem to be related to CPU setup/reset code, I checked that\n-- seems to be related to some TCG internals (as broken for single and\n multi threaded TCG).\n-- common code seems to be somehow broken, not sure if this is even\n expected to work (e.g. for single threaded TCG, hotplugged CPUs will\n never get set \"cpu->created = true\". But doesn't seem to be related to\n this)\n\n\nBased on: https://github.com/cohuck/qemu.git s390-next\nAvailable on: git@github.com:davidhildenbrand/qemu.git s390x-queue\n\n\nDavid Hildenbrand (27):\n s390x: raise CPU hotplug irq after really hotplugged\n s390x/cpumodel: fix max STFL(E) bit number\n target/s390x: get rid of next_core_id\n s390x: introduce and use S390_MAX_CPUS\n s390/tcg: turn INTERRUPT_EXT into a mask\n s390x/tcg: injection of emergency signals and extarnal calls\n s390x/tcg: STOPPED cpus can never wake up\n s390x/tcg: a CPU cannot switch state due to an interrupt\n target/s390x: factor out handling of WAIT PSW into handle_wait()\n s390x/kvm: pass ipb directly into handle_sigp()\n s390x/kvm: generalize SIGP stop and restart interrupt injection\n s390x/kvm: factor out storing of CPU status\n target/s390x: proper cpu->be convertion in s390_store_status()\n s390x/kvm: factor out storing of adtl CPU status\n s390x/kvm: drop two debug prints\n s390x/kvm: factor out SIGP code into sigp.c\n s390x/kvm: factor out actual handling of STOP interrupts\n s390x/tcg: implement SIGP SENSE RUNNING STATUS\n s390x/tcg: implement SIGP SENSE\n s390x/tcg: implement SIGP EXTERNAL CALL\n s390x/tcg: implement SIGP EMERGENCY SIGNAL\n s390x/tcg: implement SIGP CONDITIONAL EMERGENCY SIGNAL\n s390x/tcg: implement STOP and RESET interrupts for TCG\n s390x/tcg: flush the tlb on SIGP SET PREFIX\n s390x/tcg: switch to new SIGP handling code\n s390x/tcg: unlock NMI\n s390x/tcg: refactor stfl(e) to use s390_get_feat_block()\n\n hw/s390x/s390-virtio-ccw.c | 17 +-\n target/s390x/Makefile.objs | 1 +\n target/s390x/cpu-qom.h | 2 -\n target/s390x/cpu.c | 40 ++--\n target/s390x/cpu.h | 36 +++-\n target/s390x/cpu_features.c | 2 +-\n target/s390x/cpu_models.c | 2 +\n target/s390x/excp_helper.c | 98 ++++++---\n target/s390x/helper.c | 115 ++++++++--\n target/s390x/helper.h | 4 +-\n target/s390x/internal.h | 15 ++\n target/s390x/interrupt.c | 70 +++++-\n target/s390x/kvm-stub.c | 13 +-\n target/s390x/kvm.c | 470 +++--------------------------------------\n target/s390x/kvm_s390x.h | 3 +-\n target/s390x/misc_helper.c | 114 ++++------\n target/s390x/sigp.c | 504 ++++++++++++++++++++++++++++++++++++++++++++\n target/s390x/trace-events | 4 +-\n target/s390x/translate.c | 6 +-\n 19 files changed, 896 insertions(+), 620 deletions(-)\n create mode 100644 target/s390x/sigp.c"}
