Poisoned TLPs can also set the parity error bits in the PCI Configuration Space Status register. Most of the required checks (including several of the optional checks) are carried out by the integrated block. Examples: Poisoned TLP received, I installed a PCIe card from National Instruments that will be used to communicate with hardware. Fortunately, the legacy PCI compatibility concern was taken into account in this issue as well, unless the “relaxed ordering” bit The PCI_EXPRESS_UNCORRECTABLE_ERROR_SEVERITY structure describes a PCI Express (PCIe) uncorrectable error severity register of a PCIe advanced error reporting 文章浏览阅读1. Tests to detect poisoned TLP, wrong TLP sequence Poisoned TLP 通过 TLP Header 中的 EP 位来指示，EP=1 时，即表示当前 TLP 数据被破坏了。注意，是 TLP Data 被破坏了，不是Header，Header 出错可不归他管，Header 出错那就是另外的故事了。 The TD bit (bit 7 of byte 2) indicates whether a TLP digest is pro- vided at the end of the TLP.

There are both correctable and uncorrectable responses to errors such as this. Tried it on win 7 with another PC and it works! A colleague tried it on win 10 Enterprise and it works! Workstation: HP Z4 G4 Workstation I have looked everywhere, chasing the problem but PCIe Spec没有定义对没有Data Payload的TLP，其TLP包头中的EP却为1的情况，应当如何处理。注：需要注意的是，Poisoning操作只能在事务层进行。原因很简单：数据链路层和物理层在任何情况下，都不会检查TLP包头的内容，更不会修改TLP包头。 “ Poisoned TLP ” 是 PCIe 总线错误报告机制中的 Error Forwarding 的方式，具体会在后面详细介绍。 PCIe 总线 Spec 定义了两个错误报告等级。为了兼容PCI总线的错误报告机制（使用PERR#和SERR#），PCIe设备会自动将CA、UR和Poisoned TLP转换为对应的错误信息。具体这里就不详细 PCIe事务层是协议栈中的逻辑通信核心，负责管理设备间的数据传输、路由及服务质量（QoS）。其设计直接决定了PCIe系统的效率与可靠性。一、 TLP事务处理方式TLP很重要，也有很多种类。我们先来个全局的认识，看看PCIe到底定义了多少TLP种类呢？瞅下面的表格~ 这么多TLP啊，每个都是什么 The PCI Express Base Specification identifies a number of errors a PCIe port should check for, and a number of additional optional checks. Recovery from a non-fatal error may or may not, depends on device-specific software associated with the requester that initiated the transaction. The study of The Configuration Space never generates a poisoned TLP; the error/poisoned bit of the header is always set to 0. Completer Only Single Dword Endpoint x A.

PCIe-to-PCI桥接收到针对其连接的PCI设备的请求，但是该PCI设备无法处理该请求，则PCIe-to-PCI桥回复Completer Abort报文给请求者。 PCIe为了兼容PCI的PERR# SERR#, PCIe会自动将CA、UR和Poisoned TLP转换为对应的错误信息将它的错误映射到了原来的PCI的配置空间寄存器上。 An Error Poison occurs when the completion TLP EP bit is set, indicating that there is poisoned data in the payload.

So once I made the effort to figure that out for myself, I decided to write this little guide, which Poisoned TLP 通过 TLP Header 中的 EP 位来指示，EP=1 时，即表示当前 TLP 数据被破坏了。注意，是 TLP Data 被破坏了，不是Header，Header 出错可不归他管，Header 出错那就是另外的故事了。这篇文章主要介绍事务（Transaction）错误、链路流量控制（Link Flow Control）相关的错误、异常的TLP（Malformed TLP）以及内部错误（Internal Errors）等。事务（Transaction ）错误事务错误主要包括不支持的请求（Unsupported Request）、Completer Abort、非预期的Completion和Completion超时。该错误类型主要通过返回的 The PCIe Specification require that a PCIe Endpoint generate a Fatal Error Message Packet if the endpoint receives a Config Write packet that has an EP bit set, and the AER Poisoned TLP Received Severity bit is set to 1. Only data which corresponds to read or write requests (posted or non-posted) is applicable to be considered as a TLP which has been poisoned. 7. Some, however, need to be implemented. PCIe定义ACK在收到TLP数据包之后，在一定时间内必须回应ACK，也就是ACK延迟（ACK Latency）的等待时间。因应ACK/NAK流程的需要，必须实现出重新播送缓冲器（Replay Buffer）。 The document discusses various PCIe error status registers that should be checked during debugging and testing. Type 1コンフィグレーション・スペース・レジスター 5. Regardless of what card I use, everytime I try to use Data link layer的32 bit的LCRC是从data link layer到data link layer的CRC校验，可以保证两个data link layer之间的数据可靠性。但是TLP 通过switch时，switch会改变一些控制bit，但是不能修改其他的字段（Switch需要把TLP包拆开才知道要往哪里路由）。Switch拆包后再组包就会重新生成LCRC字段。在Switch内部路由时， Description: This error occurs when a received TLP has its EP (Error Poisoning) bit set, indicating that the data within the packet is corrupted or invalid. In addition, there is the EP bit, indicating that Error转发在规范中，这种错误还被称为：data poisoning，还是很形象的。这种错误只针对发送TLP或者回复的TLP中携带有数据的情况。并且是中间接收节点（像switch的UP/DP口）检测到TLP包中携带的数据有问题时，会置TLP中“EP”位为1，表示此TLP包携带的数据有问题 The Configuration Space never generates a poisoned TLP; the error/poisoned bit of the header is always set to 0. 64ビットおよび128ビットのAvalon-MM 文章浏览阅读2.
