Current kernel (V5.2) have a bug booted with "pcie_aspm=off" will lead native AER driver not loaded. Good news, there is a patch to solve such bug. Please refer the below patch for more detail information. [PATCH v3] PCI/ACPI: Improve _OSC control request granularity [v3] PCI/ACPI:...
没有成功就放弃了 今天再次测试的时候发现可以正常用了 可能最近的几个版本已经修复了这个问题 配置起来...
在收到PME_Turn_Off message之后,设备必须停止传输PM_PME messages,并开始向上游发送PME_TO_Ack Message。 3 ASPM 根据PCI-PM,处于D0状态的下游组件也会让它对应的上行链路处于D0状态。ASPM给组件提供了一种在D0状态下让链路进入低功耗的方式。如前所述,ASPM是芯片自动管理的,在软件使能了ASPM的功能(设备需要支持...
PCI-PM的D状态转换过程由下游组件主导,比如从D0到L1状态,上游组件通过Cfg Wr的TLP改变下游function的PMCSR中的状态,然后由下游组件启动链路状态切换。进入L1状态后,功耗管理软件通过PM_PME消息配置下游组件的PMCSR,设备收到PME_Turn_Off消息后,会停止传输并发送PME_TO_Ack Message。ASPM则在D0状态...
1. 更新`/etc/kernel/cmdline`,在最后追加 `pcie_aspm=off` 2. 执行`proxmox-boot-tool refresh` ## 起因 在零刻 SER7 上全新安装的 Proxmox VE8 持续在报错,看着烦,不知道是否跟长江存储的 Ti600 nvme 有关。报错关键词: ``` AER: Corrected error received ``` 在proxmox 论坛上看到有[同样问题的帖...
ASPM定义的低功耗模式,有两种:L0s和L1 (见下图 – 蓝色部分) 以上各状态的定义如下: L0: 正常工作状态 L0s:低功耗模式,恢复Latency低 L1: 更低功耗模式,恢复Latency较长 L2/L3 Ready: Power off前的过渡状态 L2: Link处于辅助供电模式,极省电

ASPM for GPU can't degrade graphical performance, because OS kernel scheduler decides when to turn off the PCIE link, if inside processes list there is at least one process with opened PCIE session, those particular link won't be shutted down. ...
