default y

depends on XEN && !XEN_DOM0 && !XEN_DOM0LESS
help
Enable Xen ring buffer based hypervisor console driver. Used
for Zephyr as unprivileged domain.
config UART_XEN_HVC_CONSOLEIO
bool "Xen hypervisor consoleio UART driver"
select SERIAL_HAS_DRIVER
depends on DT_HAS_XEN_HVC_CONSOLEIO_ENABLED && (XEN_DOM0 || XEN_DOM0LESS)
default y
help
Enable Xen hypervisor console driver. Used for Zephyr as
privileged domain (Dom0) or for Zephyr DomU in Dom0less
configuration. Dom0less configuration does not have
privileged domain. Thus, there is no console daemon and Xen
manages all domain outputs through the consoleio interface.
config XEN_HVC_INIT_PRIORITY
int "Xen hypervisor console init priority"
depends on UART_XEN_HVC || UART_XEN_HVC_CONSOLEIO
default 55
help
Set init priority for Xen HVC, should be inited before UART
console driver (HVC gets inited on PRE_KERNEL_1 stage).
config XEN_EARLY_CONSOLEIO
bool "Early printk/stdout through console_io Xen interface"
depends on UART_XEN_HVC
help
Enable setting of console_io symbol hook for stdout and printk.
Log output will become available on PRE_KERNEL_1 stage. Requires
Xen, compiled with CONFIG_DEBUG flag.
