Hello,
I am struggling to launch LSI20320IE SCSI controller on my laptop. I have TB3 PCIe enclosure with 2 slots: one is equipped with LSI SAS 2008, other is LSI20320IE. While SAS controller works flawlessly, I can’t seem to make SCSI to work. It uses PCIe-PCI-X bridge PLX 8114 rev. BC. The bridge fails to start with INVALID_DEVICE_REQEST. I already enabled Thunderbolt Pre-Boot support, disabled security. Both bridge and SCSI controller itself are visible in UEFI shell (devtree and pci commands), and it is possible to write PCI registers, however, I noticed that in UEFI I/O space is empty for the bridge BUT HWINFO64 sees the child device just fine. What should I do? During PCI enumeration in pcicfglog I see “NonHotPlugBridgeWithNoChildren”, can this be the cause? Bridge uses standard pci.sys. I also disabled DmaRemapping, i just don’t know what to do. Also, looks like CSM does not launch the SCSI OptionROM, as I don’t see any messages during boot
