config BR2_PACKAGE_HOST_QEMU_SYSTEM_MODE
	bool "Enable system emulation"
	depends on BR2_PACKAGE_HOST_QEMU_SYSTEM_ARCH_SUPPORTS
	help
	  Enables the build of the system emulator, which allows to
	  boot an entire system in Qemu.

config BR2_PACKAGE_HOST_QEMU_LINUX_USER_MODE
	bool "Enable Linux user-land emulation"
	depends on BR2_PACKAGE_HOST_QEMU_USER_ARCH_SUPPORTS
	help
	  Enables the build of the user-land emulator, which allows to
	  run user-space applications.

	  Note that system calls made by the emulated user-land are
	  serviced by the running host kernel. Therefore, if the
	  kernel headers used by your target are more recent than
	  the running host kernel, you may run into invalid system
	  calls, which may yield surprising effects.

	  "plug" both physical and virtual machines in them.
