Li Chen 54401d5abd acpi: Add machine option to disable SPCR table The ACPI SPCR (Serial Port Console Redirection) table allows firmware to specify a preferred serial console device to the operating system. On ARM64 systems, Linux by default respects this table: even if the kernel command line does not include a hardware serial console (e.g., "console=ttyAMA0"), the kernel still register the serial device referenced by SPCR as a printk console. While this behavior is standard-compliant, it can lead to situations where guest console behavior is influenced by platform firmware rather than user-specified configuration. To make guest console behavior more predictable and under user control, this patch introduces a machine option to explicitly disable SPCR table exposure: -machine spcr=off By default, the option is enabled (spcr=on), preserving existing behavior. When disabled, QEMU will omit the SPCR table from the guest's ACPI namespace, ensuring that only consoles explicitly declared in the kernel command line are registered.
