Hash: SHA256<br>
<br>
Hi all,<br>
<br>
with great pleasure, I want to request a coordinated review for<br>
merging feature/qos branch back to master:<br>
<br>
<a href="https://review.openstack.org/#/c/212170/" rel="noreferrer" target="_blank">https://review.openstack.org/#/c/212170/</a><br>
<br>
Since it's a merge patch, gerrit fails to show the whole diff that it<br>
introduces into master. To get over it, fetch the patch:<br>
<br>
$ git review -d 212170<br>
<br>
and then check the difference:<br>
<br>
$ git fetch origin && git diff origin/master...<br>
<br>
I think we should stick to review process originally suggested at [1].<br>
Specifically, since it's not reasonable to expect the whole feature<br>
branch to be reviewed by a single person, I hope multiple people will<br>
assign themselves to the job and split the pieces to review based on<br>
devref document that describes the feature [2] (Note that a new RPC<br>
push/pull mechanism is described in a separate devref section [3]).<br>
<br>
Note that we don't expect to tackle all review comments, however tiny,<br>
in feature/qos. We are happy to handle major flaws there, but for<br>
minor stuff, it's good to proceed in master. Nevertheless we are happy<br>
to get minors too and collect them for post-merge.<br>
<br>
Things we have in the tree:<br>
<br>
- - server: QoS API extension; QoS core resource extension; QoS ML2<br>
extension driver; QoS versioned objects + base for new objects; QoS<br>
supported rule types mechanism for ML2; QoS notification drivers<br>
mechanism to update SDN controllers;<br>
<br>
- - RPC: new push/pull mechanisms for versioned objects to propagate QoS<br>
objects into the agents;<br>
<br>
- - agent side: new L2 agent extensions mechanism, integrated into OVS<br>
and SR-IOV agents; QoS l2 agent extension; OVS and SR-IOV QoS drivers;<br>
ovs_lib and pci_lib changes.<br>
<br>
I suggest to split review into following logical pieces:<br>
<br>
- - API controller + service plugin + API tests;<br>
- - Versioned objects: neutron.objects.*<br>
- - ML2: supported_qos_rule_types mechanism, extension driver, update<br>
for get_device_details payload;<br>
- - RPC mechanism (push/pull), resource manager, registries +<br>
notification drivers integration;<br>
- - l2 extensions (manager, base interface) + qos extension;<br>
- - OVS integration with extension manager + OVS QoS driver + ovs_lib<br>
changes;<br>
- - SR-IOV agent integration with extension manager + SR-IOV QoS driver<br>
+ pci_lib changes;<br>
- - functional tests.<br>
<br>
We will also need to update the spec:<br>
<a href="https://review.openstack.org/#/c/199112/" rel="noreferrer" target="_blank">https://review.openstack.org/#/c/199112/</a><br>
<br>
Included test coverage:<br>
<br>
- - unit tests;<br>
- - API tests;<br>
- - functional tests (more scenarios to come in master);<br>
- - fullstack tests [4] (not in the tree since we need to merge client<br>
and base fullstack patches first).<br>
<br>
We have client patches up for review [5][6] and expect them to go in<br>
after merge of server component.<br>
<br>
We hope that we'll make fullstack in before closing the blueprint in<br>
this cycle.<br>
