kernel version 3.0.101-0.35.1 or older Certain system configurations may cause an OS crash during bootup if booted in UEFI and using the pci=pcie_bus_perf kernel parameter. Resolution The kernel update -3.0.101-0.40.1 released October 2014 includes the fix. ...
pcie_bus_tune_off 不对PCIe MPS(Max Payload Size)进行调整,而是使用BIOS配置好的默认值。 pcie_bus_safe 将每个设备的MPS都设为root complex下所有设备支持的MPS中的最大值 pcie_bus_perf 将设备的MPS设为其上级总线允许的最大MPS,同时将MRRS(Max Read Request Size)设为能支持的最大值(但不能大于设备或...
MCE的中断优先级最高,是专为硬件故障诊断而设计的,包含了关于故障的详细信息,有助于定位故障点,它并不能涵盖所有的故障类型,限于 memory, cpu cache 和 system bus。其它常见的故障比如I/O卡通常不触发MCE。 如果软硬件都支持的话,PCIe的故障会触发AER中断,它是专为PCIe硬件故障诊断而设计的,包含了故障的详细...

I could not start the pcie-bus with the function Gen2.Next, I needed to change the bus driver (pci-imx6.c), for fine tuning the bus clock frequency. I add MPLL frequency services functions (Thanks for Charle Powe i.MX6Q: Using an external reference for PCIe ): ... ...
Lew ZealandIt'll be fine, the 6600XT has a PCIe 4.0 x8 and it loses about 2% on average when restricted to PCIe 3.0. The 4060Ti should be a faster GPU so maybe it'll lose 3%. Nobody will notice.Yet people were skewering amd for a low class gpu having a smaller bus. So where'...
We also cover PCIe 6/8-pin melting failures of the past and the differences with 12VHPWR. For this content, we collaborated with Aris of Cybenetics (Hardware Busters), Der8auer, Elmor of Elmor Labs, and others to fact check the research. With the ...
