*	lguest: Add puppies which where previously missing.	Tim Ansell	2008-03-28	1	-0/+8
\| \| \| \| \| \| \|	lguest doesn't have features, it has puppies! Signed-off-by: Timothy R Ansell <mithro@mithis.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
*	Lguest support for Virtio	Rusty Russell	2007-10-23	1	-0/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
*	Remove old lguest I/O infrrasructure.	Rusty Russell	2007-10-23	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	This patch gets rid of the old lguest host I/O infrastructure and replaces it with a single hypercall "LHCALL_NOTIFY" which takes an address. The main change is the removal of io.c: that mainly did inter-guest I/O, which virtio doesn't yet support. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
*	Remove old lguest bus and drivers.	Rusty Russell	2007-10-23	1	-3/+0
\| \| \| \| \| \| \|	This gets rid of the lguest bus, drivers and DMA mechanism, to make way for a generic virtio mechanism. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
*	Move i386 part of core.c to x86/core.c.	Jes Sorensen	2007-10-23	1	-1/+1
\| \| \| \| \| \| \| \|	Separate i386 architecture specific from core.c and move it to x86/core.c and add x86/lguest.h header file to match. Signed-off-by: Jes Sorensen <jes@sgi.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
*	Rename switcher.S to x86/switcher_32.S	Rusty Russell	2007-10-23	1	-2/+4
\| \| \| \| \| \| \| \|	lguest uses a "switcher" shim mapped high to bounce between host and guest. As lguest becomes less i386-centric, we separate this code into a subdir. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
*	Move lguest guest support to arch/x86.	Rusty Russell	2007-10-23	1	-2/+2
\| \| \| \| \| \| \| \| \|	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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Andi Kleen <ak@suse.de>
*	lguest: documentation I: Preparation	Rusty Russell	2007-07-26	1	-0/+12
\| \| \| \| \| \| \| \| \| \| \|	The netfilter code had very good documentation: the Netfilter Hacking HOWTO. Noone ever read it. So this time I'm trying something different, using a bit of Knuthiness.

*	lguest: the Makefile and Kconfig	Rusty Russell	2007-07-19	1	-0/+7
	This is the Kconfig and Makefile to allow lguest to actually be compiled. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
