Userspace and vhost-net backedn test has been done with upstream kernel
in guest.
v2->v3
v2/01 - drop it since the header has been synchronized from kernel.(mst &
jason)
v3/01 - rename 'avail_wrap_counter' to 'last_avail_wrap_counter',
'event_wrap_counter' to 'avail_wrap_counter' to make it easier
to understand.(Jason)
- revise commit message.(Jason)
v3/02 - split packed ring areas size calculation to next patch.(Jason)
to not break bisect(Jason).
v3/03 - initialize packed ring region with correct size and attribute.
- remove unnecessary 'else' checks. (Jason)
v3/06 - add commit log.
- replace 'event_wrap-counter' with 'avail_wrap_counter'.
- merge common memory cache size check to
virtqueue_get_avail_bytes().(Jason)
- revise memory barrier comment.(Jason)
- check indirect descriptors by desc.len/sizeof(desc).(Jason)
- flip wrap counter with '^=1'.(Jason)
v3/07 - move desc.id/len initialization to the declaration.(Jason)
- flip wrap counter '!' with '^=1'.(Jason)
- add memory barrier comments in commit message.
v3/08 - use offsetof() when writing cache.(Jason)
- avoid duplicated memory region write when turning off event_idx
supported notification.(Jason)
- add commit log.(Jason)
- add avail & last_avail wrap counter difference description in
commit log.
v3/09 - remove unnecessary used/avail idx/wrap-counter from subsection.
- put new subsection to the end of vmstate_virtio.(Jason)
- squash the two userspace and vhost-net migration patches in
v2.(Jason)
v3/10 - reword commit message.
- this is a help not a bug fix so I would like to keep it as a
separate patch still.(Proposed a merge it by Jason)
- the virtqueue_fill() is also not like an API so I would prefer not
to touch it, please correct me if I did not get it in the right
way.(Proposed a squash by Jason)
v3/11 - squash feature bits for user space and vhost kernel/user backends.
- enable packed ring feature bit provision on host by default.(Jason)
