*	tools/virtio: add linux/module.h stub	Michael S. Tsirkin	2012-02-28	1	-0/+0
\| \| \| \| \| \|	Make the tool build again after virtio changes broke it. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
*	virtio: rename virtqueue_add_buf_gfp to virtqueue_add_buf	Rusty Russell	2012-01-12	2	-16/+8
\| \| \| \| \| \| \| \| \|	Remove wrapper functions. This makes the allocation type explicit in all callers; I used GPF_KERNEL where it seemed obvious, left it at GFP_ATOMIC otherwise. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Reviewed-by: Christoph Hellwig <hch@lst.de>
*	virtio: harsher barriers for rpmsg.	Rusty Russell	2012-01-12	2	-1/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	We were cheating with our barriers; using the smp ones rather than the real device ones. That was fine, until rpmsg came along, which is used to talk to a real device (a non-SMP CPU). Unfortunately, just putting back the real barriers (reverting d57ed95d) causes a performance regression on virtio-pci. In particular, Amos reports netbench's TCP_RR over virtio_net CPU utilization increased up to 35% while throughput went down by up to 14%. By comparison, this branch is in the noise.

*	virtio_test: support event index	Michael S. Tsirkin	2011-05-30	1	-2/+17
\| \| \| \| \| \| \|	Add ability to test the new event idx feature, enable by default. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
*	tools/virtio: virtio_test tool	Michael S. Tsirkin	2010-12-09	5	-0/+487
\| \| \| \| \| \| \| \| \| \| \|	This is the userspace part of the tool: it includes a bunch of stubs for linux APIs, somewhat simular to linuxsched. This makes it possible to recompile the ring code in userspace. A small test example is implemented combining this with vhost_test module. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
*	vhost test module	Michael S. Tsirkin	2010-12-09	2	-0/+3
	This adds a test module for vhost infrastructure. Intentionally not tied to kbuild to prevent people from installing and loading it accidentally. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
