While testing our vDPA driver with QEMU we found that vhost_vdpa was missing some support for PACKED VQs. Adding these helped us get further in our testing. The first patch makes sure that the vhost_vdpa vqs are given the feature flags, as done in other vhost variants. The second and third patches use the feature flags to properly format and pass set/get_vq requests. v1: - included wrap counter in packing answers for VHOST_GET_VRING_BASE - added comments to vhost_virtqueue fields last_avail_idx and last_used_idx v0: https://lists.linuxfoundation.org/pipermail/virtualization/2023-April/066253.html - initial version Shannon Nelson (3): vhost_vdpa: tell vqs about the negotiated vhost: support PACKED when setting-getting vring_base vhost_vdpa: support PACKED when setting-getting vring_base drivers/vhost/vdpa.c | 34 ++++++++++++++++++++++++++++++---- drivers/vhost/vhost.c | 18 +++++++++++++----- drivers/vhost/vhost.h | 8 ++++++-- 3 files changed, 49 insertions(+), 11 deletions(-) -- 2.17.1 _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
