    • In one embodiment of the invention, a method of semaphoring between a system firmware and ACPI subsystem, includes: prior to entering a critical section by a first entity, checking a turn flag to determine if a second entity has a turn to access a critical section; if the second entity has the turn, then checking an In flag of the second entity to determine if the second entity is in the critical section; if the second entity is in the critical section, then waiting for the second entity to exit the critical section; and entering the critical section by the first entity. The method may further include: if the second entity is not in the critical section, then entering the critical section by the first entity.
    • 在本发明的一个实施例中,一种在系统固件和ACPI子系统之间进行信号的方法包括:在由第一实体进入关键部分之前,检查转弯标志以确定第二实体是否具有接近临界部分的转弯 ; 如果第二实体具有转弯,则检查第二实体的In标志以确定第二实体是否在临界区; 如果第二个实体处于临界区,那么等待第二个实体退出临界区; 并由第一实体进入关键部分。 该方法还可以包括:如果第二实体不在临界区,则由第一实体进入临界区。
