While many ARM64 devices lack ACPI, the writing seems to be on the wall of UEFI/ACPI potentially taking over. Some common devices may need ACPI table support. Presently I think it is worth removing the dependancy on CONFIG_EXPERT. I am rather tempted to add defaulting enabled, but I'm not yet confident of going that far yet. Signed-off-by: Elliott Mitchell --- I hope a popular ARM device capable of running Xen will soon be running Xen on ACPI/UEFI, but it isn't quite there yet. As such I would like to have "default y", but I don't think that is likely to be accepted yet. --- xen/arch/arm/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/xen/arch/arm/Kconfig b/xen/arch/arm/Kconfig index 2777388265..f43d9074f9 100644 --- a/xen/arch/arm/Kconfig +++ b/xen/arch/arm/Kconfig @@ -32,7 +32,7 @@ menu "Architecture Features" source "arch/Kconfig" config ACPI - bool "ACPI (Advanced Configuration and Power Interface) Support" if EXPERT + bool "ACPI (Advanced Configuration and Power Interface) Support" depends on ARM_64 ---help---
