The first 3 patches fix various problems I have encountered with
virtio_test (they may go without this series, but I included to allow you
to test the series).
Patch 4 is in preparation of patch 5, moving the feature negotiation when
we initialize the device.
Patch 5 add the support of vhost-vdpa in virtio_test
Patch 6 add vdpa_test.ko based on vdpa_sim_test.c, so we can reuse most of
the code coming from the vdpa_sim framework.
I tested in this way:
$ modprobe vdpa_sim
$ modprobe vhost-vdpa
# load the vdpasim_test device
$ insmod vdpa_test.ko
# create a new vdpasim_test device
$ vdpa dev add mgmtdev vdpasim_test name dev0
I wonder what's the benefit of using a dedicated test device other
than networking? (already a loopback device anyhow).
The main advantage I was thinking is that we can extend it at will to
try to cover as much as possible all the paths that maybe with net we
can't (indirect, reset, etc.).
Plus it should be easier to test vhost-vdpa this way without using QEMU.
Do you think this is redundant?
Thanks,
Stefano
