Correctable Error Status Register (Offset 10h) 可恢复错误状态寄存器,表示硬件发生了可恢复错误,由硬件自行纠正之后上报错误状态,注意,一般来说,可纠正错误不会影响正常业务。 [0] Receiver Error Status Link errors都可以认为是receiver error,可能原因: 可能是协商过程中出现误码; 可能是由于lane处于L0时的MAC...

Advisory Non-Fatal Error Cases主要由检测agent(Requester,Completer, or Receiver)和特定错误情况来确定。在这种情况下,如果打开AER通过发送ERR_COR,而不是发送ERR_NONFATAL,没有AER的情况不会发送任何错误消息。Completer通常发送一个带有Unsupported Request或Completer Abort (UR/CA)状态的Completion,以表示non-post ...
