This series introduces a new machine option, spcr=on|off, allowing users to disable the ACPI SPCR (Serial Port Console Redirection) table. By default, SPCR is enabled. Disabling it can help ensure that the guest's console behavior is determined solely by kernel command-line parameters on arch like arm64, avoiding unintended serial console configurations imposed by firmware.
Also add tests on AArch64 and RISC-V virt machines using TCG and UEFI boot. Changes since v1: - Add bios-tables-test for RISC-V and ARM as suggested by - Add Acked-by from Michael S.
