This patch depends on kernel-specific ACPICA configuration, can I submit it to ACPICA projects? On 2023/2/2 17:31, Rafael J.

ACPI core subsystem initialization will fail when Kernel disabled PCI but ACPI tables still have PCI config address spaces. Enable ACPI_ADR_SPACE_PCI_CONFIG in acpi_gbl_default_address_spaces only when ACPI_PCI_CONFIGURED is defined.
