Laszlo Ersek 3c23402d40 hw/isa/lpc_ich9: inject the SMI on the VCPU that is writing to APM_CNT ... Commit 4d00636e97 ("ich9: Add the lpc chip", Nov 14 2012) added the ich9_apm_ctrl_changed() ioport write callback function such that it would inject the SMI, in response to a write to the APM_CNT register, on the first CPU, invariably. Since this register is used by guest code to trigger an SMI synchronously, the interrupt should be injected on the VCPU that is performing the write. apm_ioport_writeb() is the .write callback of the "apm_ops" MemoryRegionOps [hw/isa/apm.c]; it is parametrized to call ich9_apm_ctrl_changed() by ich9_lpc_init() [hw/isa/lpc_ich9.c], via apm_init(). Therefore this change affects no other board. ich9_generate_smi() is an unrelated function that is called by the TCO watchdog; a watchdog is likely in its right to (asynchronously) inject interrupts on the first CPU only. This patch allows the combined edk2/OVMF SMM driver stack to work with multiple VCPUs on TCG, using both qemu-system-i386 and qemu-system-x86_64.
