# UTSM dual-kernel hypercall driver configuration

config UTSM_HCALL
	tristate "UTSM dual-kernel hypercall and IPC driver"
	default y
	help
	  This driver enables communication between the Linux guest and
	  the UTSM monitor kernel in the Deshab dual-kernel architecture.

	  When loaded, it:
	  - Probes for the UTSM monitor via a VMCALL PING hypercall
	  - Maps the IPC shared memory ring buffer
	  - Registers /dev/utsm for userspace IPC message passing

	  If running on bare metal or a non-UTSM hypervisor, the driver
	  loads in passive mode (no /dev/utsm registered).

	  If unsure, say Y for UTSM guest builds, N otherwise.

config UTSM_EARLY_CONSOLE
	bool "Redirect kernel printk to UTSM serial console"
	depends on UTSM_HCALL
	default n
	help
	  Redirects Linux kernel console output to the UTSM monitor's
	  serial port via UTSM_HCALL_CONSOLE_WRITE hypercalls. Useful
	  for early boot debugging when the guest's own serial is not
	  configured.

	  If unsure, say N.
