tools/virtio: stub out strong barriers

2012-02-28T07:13:16Z

The tool should never use them, abort if it does. Signed-off-by: Michael S. Tsirkin

tools/virtio: add linux/hrtimer.h stub

2012-02-28T07:13:14Z

Make tool build after virtio changes broke it. Signed-off-by: Michael S. Tsirkin

tools/virtio: add linux/module.h stub

2012-02-28T07:13:12Z

Make the tool build again after virtio changes broke it. Signed-off-by: Michael S. Tsirkin

virtio: rename virtqueue_add_buf_gfp to virtqueue_add_buf

2012-01-12T05:14:42Z

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 Reviewed-by: Christoph Hellwig

virtio: harsher barriers for rpmsg.

2012-01-12T05:14:42Z

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

2011-05-30T01:44:15Z

Add ability to test the new event idx feature, enable by default. Signed-off-by: Rusty Russell

tools/virtio: virtio_test tool

2010-12-09T14:00:22Z

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

vhost test module

2010-12-09T14:00:21Z

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
