| enable_and_wait | Enable Interrupts and wait for the next interrupt (HLT instruction) According to https://lists.freebsd.org/pipermail/freebsd-current/2004-June/029369.html, this exact sequence of assembly instructions is guaranteed to be atomic. This is important, because another CPU could call wakeup_core right when we decide to wait for the next interrupt. |
