Hi list, I'm working on the instrumentation of each (translated) basic block. The host arch is x86_64. At the beginning of each translated basic block, I added some instructions to do some accounting. Then under some conditions I need to raise an NMI inside a translated basic block. The following is (part of ) what I added to tcg_gen_code_common(). /* movq EXCP02_NMI,%rdi */ tcg_out_movi(s, TCG_TYPE_I64, TCG_REG_RDI, EXCP02_NMI); /* callq helper_raise_interrupt(EXCP02_NMI) */ tcg_out8(s, 0xe8); tcg_out32(s, (tcg_target_long)raise_exception - (tcg_target_long)s->code_ptr - 4); It seems that this NMI is not handled properly in cpu_exec(). I also tried cpu_interrupt(), this also did not work. What I want to do is to raise an NMI inside a translated basic block, any suggestions? Thanks, Jiaqing
