摘要： Interrupts are directed to currently idle processors. Which of a number of processors of a computing system that are currently idle is determined. An interrupt is received and directed to one of the currently idle processors for processing. Determining which processors are currently idle can be accomplished by monitoring each processor to determine whether it has entered an idle state. When a processor has entered an idle state, it is thus determined that the processor is currently idle. Where just one processor is currently idle, an interrupt is directed to this processor. Where more than one processor is currently idle, one of these processors is selected to which to deliver an interrupt, such as in a round-robin manner. Where no processor is currently idle, then one of the processors is selected to which to deliver an interrupt.

摘要： A computing device includes a processor, firmware, a hardware component, and a debugging module. The firmware stores error decoding logic particular to the computing device. The hardware component detects an error in the computing device, and responsively issues an interrupt and halts the processor such that the processor cannot execute any more computer-readable code. The debugging module loads the logic from the firmware at reset and executes the logic responsive to the interrupt. The debugging module does not use the processor to execute the logic, the firmware is not part of the debugging module, and the debugging module is not part of the hardware component. The firmware may also store a mapping between registers of the hardware component and field-replaceable hardware units of the computing device, which the debugging module loads at reset and uses when executing the error decoding logic to determine which unit has caused the error.

摘要： The last value of an element of a computing system is continually stored within a first register. The element is cleared during any restart or reset of the computing system. The last value is relevant to debugging of the computing system when the computing system fails to perform as expected and/or as desired. Upon receiving an instruction to reset the computing system via a first reset signal corresponding to pressing of a reset button or a second reset signal corresponding to a baseboard management controller issuing a reset command, the last value of the element as stored within the first register is copied to a second register. The computing system is then reset. The last value of the element as stored within the second register persists within the second register during this type of reset, but is cleared during any other reset or restart of the computing system.

摘要： Internal timestamp counter instructions are instead processed in reference to an external counter. A processor receives an instruction to access an internal timestamp counter of the processor, such as from software code containing the instruction that is currently being executed by the processor. The processor processes the instruction, however, in reference to an external counter apart from the processor, instead of in reference to the internal timestamp counter. The code is thus unaware that the instruction is being processed in reference to the external counter instead of in reference to the internal timestamp counter, and does not have to be rewritten or recompiled to take advantage of the external counter. That is, the code still has instructions that are intended to access the internal timestamp counter, and these instructions are instead executed in reference to an external counter, such as a phase-locked loop (PLL) clock of a Northbridge controller.

摘要翻译： 内部时间戳计数器指令是相对于外部计数器进行处理的。 处理器接收诸如从包含当前由处理器执行的指令的软件代码访问处理器的内部时间戳计数器的指令。 然而，处理器处理指令，而不是参考内部时间戳计数器，而是参考与处理器分离的外部计数器。 因此，代码不知道该指令是在引用外部计数器而不是参考内部时间戳计数器的情况下进行处理的，并且不必重写或重新编译以利用外部计数器。 也就是说，代码仍然具有旨在访问内部时间戳记计数器的指令，并且相对于外部计数器执行这些指令，例如北桥控制器的锁相环（PLL）时钟。
