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).
Thanks
