	  Lguest is a tiny in-kernel hypervisor.  Selecting this will
	  allow your kernel to boot under lguest.  This option will increase
	  your kernel size by about 10k.  If in doubt, say N.

	  If you say Y here, make sure you say Y (or M) to the virtio block
	  and net drivers which lguest needs.
Move lguest guest support to arch/x86. Lguest has two sides: host support (to launch guests) and guest support (replacement boot path and paravirt_ops). This moves the guest side to arch/x86/lguest where it's closer to related code.

lguest: select CONFIG_TTY to build properly. Fix kconfig warning for LGUEST_GUEST config by selecting TTY: warning: (KVMTOOL_TEST_ENABLE && LGUEST_GUEST) selects VIRTIO_CONSOLE which has unmet direct dependencies (VIRTIO && TTY) Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Joe Millenbach <jmillenbach@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> 2013-02-15 02:55:06 +08:00			`select TTY`
LGUEST_GUEST: fix unmet direct dependencies (VIRTUALIZATION && VIRTIO) Honor the kconfig menu hierarchy to remove kconfig dependency warnings: VIRTIO and VIRTIO_RING are subordinate to VIRTUALIZATION. warning: (LGUEST_GUEST) selects VIRTIO which has unmet direct dependencies (VIRTUALIZATION) warning: (LGUEST_GUEST && VIRTIO_PCI && VIRTIO_BALLOON) selects VIRTIO_RING which has unmet direct dependencies (VIRTUALIZATION && VIRTIO) Reported-by: Toralf F_rster <toralf.foerster@gmx.de> Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> 2011-01-02 03:08:46 +08:00			`select VIRTUALIZATION`
Lguest support for Virtio This makes lguest able to use the virtio devices. We change the device descriptor page from a simple array to a variable length "type, config_len, status, config data..." format, and implement virtio_config_ops to read from that config data. We use the virtio ring implementation for an efficient Guest <-> Host virtqueue mechanism, and the new LHCALL_NOTIFY hypercall to kick the host when it changes. We also use LHCALL_NOTIFY on kernel addresses for very very early console output. We could have another hypercall, but this hack works quite well.
