Hi, How can the kernel read hardware information for a PCIe card if ACPI in the BIOS doesn't have it? The DSDT/ACPI information doesn't contain information about an external PCIe inserted in the motherboard, so how can the Kenerl discover its hardware information? If the kernel has the rule of not hardcoding hardware information in its driver, what is the method to get hardware information for a PCIe not part of the motherboard? And the same question for ARM device trees. How can the driver find hardware information about a PCIe card that is not in the loaded DTB for the system?
