I would like to ask: on RISC‑V platforms, if we need to manage dependencies between multiple PCI Host Bridges, could this be addressed by adding a call to acpi_dev_clear_dependencies(device) at the end of the acpi_pci_root_add enumeration function? Initialization order dependencies can be defined via the ACPI _DEP method in the DSDT. For example, if host bridge B depends on host bridge A, bridge B should not be enumerated until bridge A is fully initialized. Best regards, Yuye
