To be used on top of: [PATCH 0/4] vhost-user: protocol updates https://lists.gnu.org/archive/html/qemu-devel/2015-07/msg03842.html
v2 -> v3: - Addressed Michael S. Tsirkin's comments: - Fixed a typo in patch 2/3 message - MQ - I left it there for completeness, it will be moved once the "protocol" bits will be 'active' - unit-test - The bits were added to GET_FEATURES, not GET_PROTOCOL_FEATURES, no need to make any changes - Added a new patch (1/3) that removes the unnecessary virtio bits related to vhost-user backend. v1 -> v2: - Addressed Michael S. Tsirkin's comments: - Prefer a white-list of supported features - Add a unit-test to show the problem we are trying to solve (run the unit-test before the patch and it will fail) Currently the vhost-user supported features are not evaluated. The way I see it, and please correct me, the best way to do this is to: 1. Get the backend features on vhost init. 2. Check them one by one (white-list) against all the currently supported virtio features. 3. All other code should remain the same.
