  "message": "hw/isa/lpc_ich9: inject the SMI on the VCPU that is writing to APM_CNT\n\nCommit 4d00636e97b7 (\"ich9: Add the lpc chip\", Nov 14 2012) added the\nich9_apm_ctrl_changed() ioport write callback function such that it would\ninject the SMI, in response to a write to the APM_CNT register, on the\nfirst CPU, invariably.\n\nSince this register is used by guest code to trigger an SMI synchronously,\nthe interrupt should be injected on the VCPU that is performing the write.\n\napm_ioport_writeb() is the .write callback of the \"apm_ops\"\nMemoryRegionOps [hw/isa/apm.c]; it is parametrized to call\nich9_apm_ctrl_changed() by ich9_lpc_init() [hw/isa/lpc_ich9.c], via\napm_init(). Therefore this change affects no other board.\n\nich9_generate_smi() is an unrelated function that is called by the TCO\nwatchdog; a watchdog is likely in its right to (asynchronously) inject\ninterrupts on the first CPU only.\n\nThis patch allows the combined edk2/OVMF SMM driver stack to work with\nmultiple VCPUs on TCG, using both qemu-system-i386 and qemu-system-x86_64.\n\nCc: Paolo Bonzini \u003cpbonzini@redhat.com\u003e\nCc: Gerd Hoffmann \u003ckraxel@redhat.com\u003e\nCc: Jordan Justen \u003cjordan.l.justen@intel.com\u003e\nCc: Michael Kinney \u003cmichael.d.kinney@intel.com\u003e\nCc: \"Michael S.
