PCIe设备在CFG_COMPLETE阶段通过TS2确认已协商好的Link width和Lane numbers并且完成lane deskew,最后在CFG_IDLE阶段发送Idle data,然后进入L0。 4.Recovery 在recovery状态可以实现如下功能:lchange the data raten例如从2.5 GT/s切换到8GT/s、从8GT/s切换到16GT/slre-establish bit lock, Symbol lock or Bloc...
PCIe lane polarity inversion Link width negotiation Dynamic link width change Speed negotiation Support for four DW End-to-End TLP prefixes and a vendor-defined fabric port TLP prefix Power management: Support for ASPM L0s Support for ASPM L1 Support for L1 substates (L1.0, L1.1, and L1.2)...
If so, how will the Retimer handle the link width change on both pseudo-links? L0p will be supported in a Link with Retimers. Retimers supporting the Flit Mode are mandated to support L0p. The L0p width is negotiated between the Ports – both pseudo-ports in the same direction ...
为了启动 8 GT/s EQ,DSP 在 2.5 GT/s 或 5 GT/s 速率的 Recovery.RcvrLock 状态通过Speed Change 位置一的 EQ TS1 请求切换速度,来通知 USP 其想要针对更高速率进行 EQ。USP 在收到 Speed Change 位置一的 EQ TS1 后,若 USP 自身也有意切到更高的速率,USP 应在 Recovery 状态响应 DSP 并提议切...

(3) Speed Change。因为第一次进入L0状态时,速率是2.5GT/s. 当需要进行速率调整5.0GT/s或者8.0GT/s时,需要进入Recovery状态进行Speed Change. 这个阶段,Bit Lock、Symbol Lock等都需要重新获取; (4) 需要重新调整PCIe链路的Width; (5) 软件触发retrain操作; ...
