@strongtz could your share your image without PCIe DXE or describe how you removed it? Best regards

Is this still an issue with latest changes and Linux booted with a device tree?
ACPI-wise with generic OS drivers I'm afraid we can't do much. For anything more complex than a single device on bus 1, I guess custom ECAM accessors are needed (similar to the old PciExpressLib implementation in UEFI, but that was also broken).
I can confirm that PCIe switch works without any problem on Linux 6.2 + devicetree now. Gonna test ACPI later

looks like the switch doesn't get recognized in Linux with ACPI

I can confirm that PCIe switch works without any problem on Linux 6.2 + devicetree now.
Well, I think there are still hidden problems. The NVMe devices are not detected sometimes with device tree boot. 0~4 drives can get detected on each boot. And even if they're all detected, timeouts could occur.

Do the NVME drives behind your switch work in UEFI if you increase the bus range to 15?:
Same can be done for ACPI:
Set both max range and length to 15.
I got my hands on a board with 2x RTL8125 behind an ASM1182e. Both the switch and NICs appear to enumerate correctly, but the Realtek driver does not load (bad resource map?)

Do the NVME drives behind your switch work in UEFI if you increase the bus range to 15?:
No, I don't get anything after patching the code:

Can we close this as fixed now?
ACPI support for switches is going to need OS-specific quirks.
